# TaniSMART Community Chat Feature
## Deskripsi Fitur
Fitur Komunitas TaniSMART memungkinkan pengguna aplikasi untuk saling berkomunikasi, berbagi pengalaman, dan mendiskusikan topik-topik terkait pertanian. Fitur ini menggantikan fitur Harga Pasar yang sebelumnya ada di aplikasi.
## Fungsionalitas
- Pesan realtime menggunakan Supabase
- Kategorisasi pesan (Umum, Pertanian, Teknologi, Bantuan)
- Tampilan pesan yang membedakan pesan pengirim dan penerima
- Informasi waktu pengiriman pesan
- Dukungan multi-baris untuk pesan panjang
## Cara Penggunaan
1. Buka halaman Komunitas dari menu utama aplikasi
2. Pilih kategori diskusi yang diinginkan dari dropdown di bagian atas
3. Lihat pesan-pesan yang ada atau refresh dengan menarik layar ke bawah
4. Kirim pesan baru dengan mengetik di kolom input dan menekan tombol kirim
## Setup Database Supabase
Untuk mengaktifkan fitur chat komunitas, ikuti langkah-langkah berikut di Supabase:
1. Login ke dashboard Supabase project Anda
2. Buka SQL Editor
3. Jalankan perintah SQL yang terdapat pada file `supabase_setup.sql`
4. Verifikasi bahwa tabel `community_messages` dan `profiles` telah terbuat
5. Pastikan Row Level Security (RLS) dan kebijakan (policies) sudah diaktifkan
6. Verifikasi bahwa realtime replication sudah diaktifkan untuk tabel `community_messages`
## Struktur Kode
Fitur ini menggunakan Supabase untuk menyimpan dan menampilkan pesan secara realtime:
- `CommunityScreen` berisi implementasi UI dan logika untuk chat
- Messages disimpan dalam tabel `community_messages` di Supabase
- Realtime subscriptions digunakan untuk memperbarui pesan secara otomatis
## Teknologi yang Digunakan
- Flutter untuk UI dan logika aplikasi
- Supabase untuk autentikasi dan database
- Supabase Realtime untuk fitur chat realtime
- PostgreSQL untuk penyimpanan data
## Catatan Penting
- Pengguna harus login terlebih dahulu untuk menggunakan fitur ini
- Fitur ini menggunakan free tier Supabase, jadi tidak ada biaya tambahan
- Batasan pada free tier Supabase: 500 ribu baris database, 5GB storage, dan 2GB bandwidth per bulan

# BAB 2 - LANDASAN TEORI DAN PENELITIAN TERDAHULU
## 2.1 Penelitian Terdahulu
Perancangan tugas akhir memerlukan beberapa referensi untuk dijadikan pedoman dalam perancangan tugas akhir ini. Membaca literatur serta referensi yang berkaitan akan mempermudah perancangan dan pengerjaan tugas akhir dengan baik dan terstruktur. **Dalam konteks Design Science Research**, penelitian terdahulu memberikan dasar teoritis dan praktis untuk merancang solusi teknologi yang sesuai dengan kebutuhan pengguna. Karya tulis ilmiah yang berkaitan serta telah diteliti sebelumnya:
### 2.1.1 AI dalam Deteksi Penyakit Tanaman untuk Desain Solusi
**Ramesh, B. E. et al. (2025)** dalam penelitian terbaru yang dipublikasikan di IJIRSET memperkenalkan **AI Plant Doctor: An AI-Powered Leaf Disease Scanner for Sustainable Agriculture using Deep Learning and Mobile Computing**, sebuah solusi Android inovatif yang mengintegrasikan Convolutional Neural Networks (CNN) untuk klasifikasi penyakit daun dengan akurasi 92%. Model CNN tersebut kemudian dioptimasi ke format TensorFlow Lite guna memungkinkan inferensi on-device secara real-time (≤200 ms per citra) pada smartphone berdaya komputasi terbatas, tanpa bergantung koneksi internet.
Sebelum klasifikasi, tiap citra daun dipra-proses menggunakan OpenCV meliputi resize ke 224×224 piksel, normalisasi saluran RGB, serta filtrasi noise seperti bayangan dan pencahayaan tidak merata. Hasil diagnosa disajikan melalui antarmuka Streamlit dengan alur **"Capture, Diagnosa, Tindakan"** yang mudah diikuti, serta dilengkapi fitur offline untuk penggunaan di lapangan dan opsi cloud untuk penyimpanan dan skalabilitas. Aplikasi juga mengarahkan petani ke sumber-sumber pengobatan terkini melalui Google API.
**Evaluasi penerapan** menunjukkan bahwa 85% petani menilai antarmuka intuitif, dan 90% memanfaatkan mode offline untuk mempercepat diagnosa hingga 30% dibanding inspeksi manual. Secara keseluruhan, AI Plant Doctor diperkirakan dapat menurunkan kehilangan hasil panen hingga 15% serta mengurangi pemakaian pestisida berlebih.
**Keterbatasan penelitian** ini antara lain cakupan dataset yang terbatas pada 14 spesies tanaman tanpa variasi regional, ketahanan pra-prosesing dalam kondisi citra ekstrem, serta basis pengetahuan offline yang bersifat umum.
**Relevansi dan Penyesuaian untuk Penelitian Saat Ini** dalam konteks DSR terletak pada pemanfaatan pembelajaran dari artefak yang sudah ada untuk merancang solusi yang lebih baik. Penelitian tugas akhir ini akan mengadopsi **Gemini API** yang merupakan layanan AI mutakhir dengan tingkat akurasi tinggi untuk identifikasi penyakit tanaman via citra daun. Gemini API menyediakan model vision yang terlatih pada korpus data internasional lebih luas, sehingga mampu mendeteksi gejala penyakit yang lebih variatif dan regional. **Gap yang diatasi** adalah adaptasi teknologi AI untuk konteks petani Indonesia dengan mempertimbangkan kemudahan penggunaan dan penerimaan teknologi.
### 2.1.2 Framework Adopsi Teknologi untuk Analisis Kebutuhan
**Kevin Mallinger et al. (2024)** memperkenalkan kerangka kerja untuk **"Breaking the barriers of technology adoption: Explainable AI for requirement analysis and technology design in smart farming"** yang dipublikasikan dalam Smart Agricultural Technology. Penelitian ini tidak membahas deteksi penyakit tanaman secara langsung, melainkan fokus pada bagaimana Explainable AI (XAI) dapat digunakan untuk menganalisis kesiapan dan hambatan adopsi teknologi pertanian cerdas, khususnya di sektor peternakan presisi (Precision Livestock Farming).
**Metode penelitian** yang digunakan meliputi survei terhadap 266 petani di Uni Eropa dan Timur Tengah mengumpulkan 20 pertanyaan terkait infrastruktur, sikap, dan akses pasar. Data diklaster menjadi tiga kelompok kesiapan ("Not Ready", "Partially Ready", "Ready") menggunakan k-means dan divalidasi dengan metrik rCIP dan WB Index. Sebuah model Random Forest digunakan untuk memprediksi klaster kesiapan berdasarkan jawaban survei. Teknik XAI—termasuk Partial Dependence Plots (PDP), Individual Conditional Expectation (ICE), SHAP, dan LIME—diterapkan untuk mengungkap fitur mana (pertanyaan survei) yang paling mempengaruhi prediksi kesiapan teknologi.
**Hasil dan temuan utama** menunjukkan bahwa akses informasi tentang teknologi dan distributor serta kemudahan memperoleh perangkat di pasar adalah hambatan paling signifikan di semua klaster. Ketersediaan bantuan teknis dan pelatihan krusial untuk memindahkan petani dari klaster "Not Ready" ke "Ready". Persepsi bahwa teknologi dapat mengatasi kekurangan tenaga kerja dan kemudahan operasional terbukti mempengaruhi tingkat adopsi.
**Keterbatasan penelitian** ini adalah fokus pada peternakan presisi, belum diuji pada konteks pertanian tanaman (termasuk diagnostik penyakit daun).
**Relevansi dalam Design Science Research** terletak pada framework analisis adopsi teknologi yang dapat diadaptasi untuk **tahap identifikasi masalah dan analisis kebutuhan** dalam penelitian saat ini. Penelitian Mallinger memberikan dasar metodologis untuk memahami faktor-faktor yang mempengaruhi penerimaan teknologi oleh petani, yang menjadi input penting untuk merancang aplikasi TaniSMART yang mudah diterima dan digunakan oleh petani di Desa Sumbersalam.
### 2.1.3 Konteks Adopsi Smart Farming Technology di Indonesia
**Agussabti et al.** dalam penelitian **"Farmers' perspectives on the adoption of smart farming technology to support food farming in Aceh Province, Indonesia"** memberikan gambaran spesifik tentang perspektif petani terhadap adopsi teknologi smart farming untuk mendukung pertanian pangan di Indonesia. Penelitian ini menganalisis kesiapan adopsi smart farming technology (SFT) pada tiga komoditas pangan utama di Provinsi Aceh, yaitu **padi, jagung, dan kentang**.
**Metodologi penelitian** menggunakan quota sampling dengan total **258 responden** yang terdiri dari 210 petani (70 petani per komoditas) dan 48 penyuluh pertanian. Pengukuran kesiapan adopsi SFT dilakukan dengan memperkenalkan berbagai model, gambar, video, dan aplikasi RITX kepada responden. Data yang terkumpul dianalisis menggunakan Mann-Whitney dan Kruskal-Wallis untuk dua atau lebih kategori.
**Temuan utama penelitian** menunjukkan bahwa baik petani maupun penyuluh memiliki persepsi positif terhadap penerapan smart farming technology. Namun, dari segi kesiapan, petani memiliki tingkat kesiapan yang relatif lebih rendah dibandingkan penyuluh karena kapasitas mereka yang terbatas. Faktor-faktor yang menghambat penggunaan SFT pada komoditas pangan, khususnya di komunitas petani kecil, meliputi perubahan iklim global, kualitas sumber daya manusia petani yang rendah, dan terbatasnya akses terhadap modal serta input pertanian.
**Penelitian ini mengidentifikasi** bahwa petani kecil umumnya memiliki lahan yang relatif kecil, akses terbatas terhadap modal dan input pertanian, serta menanam berbagai jenis komoditas sesuai musim. Hasil penelitian menekankan pentingnya fokus pada pembangunan ekonomi dan kapasitas petani dengan menyediakan perangkat SFT yang sesuai untuk mengatasi biaya investasi yang tinggi dan memberikan keterampilan teknis untuk aplikasinya.
**Relevansi untuk Design Science Research** terletak pada pemahaman mendalam tentang **readiness gap** dan **capacity constraints** yang menjadi input kritis untuk **tahap identifikasi masalah** dan **definisi objektif solusi** dalam penelitian saat ini. Penelitian Agussabti memberikan konteks empiris tentang karakteristik petani Indonesia yang mempengaruhi penerimaan teknologi, khususnya terkait kemudahan penggunaan, affordability, dan kebutuhan capacity building. Hal ini menjadi dasar penting untuk merancang aplikasi TaniSMART yang sesuai dengan kondisi dan kemampuan petani di Desa Sumbersalam, Bondowoso.

**Design Science Research** adalah paradigma penelitian yang fokus pada penciptaan dan evaluasi artefak teknologi yang inovatif untuk memecahkan masalah praktis yang penting (Hevner et al., 2004). Dalam konteks penelitian ini, DSR digunakan sebagai kerangka metodologis untuk merancang, mengembangkan, dan mengevaluasi aplikasi TaniSMART.
**Framework DSR** terdiri dari enam tahapan utama:
1. **Identifikasi Masalah dan Motivasi**: Mengidentifikasi masalah spesifik dalam adopsi teknologi AI untuk deteksi penyakit tanaman di Desa Sumbersalam
2. **Definisi Objektif Solusi**: Menetapkan tujuan yang jelas untuk aplikasi TaniSMART berdasarkan kebutuhan petani
3. **Perancangan dan Pengembangan**: Merancang arsitektur aplikasi dan mengimplementasikan fitur-fitur menggunakan Gemini API dan Flutter
4. **Demonstrasi**: Menunjukkan bahwa artefak dapat digunakan untuk memecahkan masalah yang diidentifikasi
5. **Evaluasi**: Menilai tingkat penerimaan dan kemudahan penggunaan aplikasi melalui pengujian dengan petani
6. **Komunikasi**: Menyampaikan hasil penelitian kepada komunitas akademis dan praktisi
**Relevansi DSR** untuk penelitian ini adalah memberikan legitimasi akademis untuk pengembangan teknologi dengan pendekatan studi kasus tunggal, yang sesuai dengan fokus penelitian pada Desa Sumbersalam sebagai konteks spesifik.
### 2.2.2 Technology Acceptance Model (TAM)
**Technology Acceptance Model** yang dikembangkan oleh Davis (1989) menjelaskan faktor-faktor yang mempengaruhi penerimaan teknologi oleh pengguna. Model ini sangat relevan untuk mengevaluasi penerimaan aplikasi TaniSMART oleh petani.
**Komponen utama TAM** meliputi:
- **Perceived Usefulness** (Kegunaan yang Dirasakan): Sejauh mana pengguna percaya bahwa teknologi akan meningkatkan kinerja mereka
- **Perceived Ease of Use** (Kemudahan Penggunaan yang Dirasakan): Sejauh mana pengguna percaya bahwa teknologi mudah digunakan
- **Behavioral Intention** (Niat Perilaku): Kecenderungan pengguna untuk mengadopsi teknologi
- **Actual System Use** (Penggunaan Sistem Aktual): Perilaku penggunaan teknologi yang sebenarnya
**Dalam konteks penelitian ini**, TAM digunakan sebagai kerangka evaluasi untuk mengukur tingkat penerimaan aplikasi TaniSMART oleh petani di Desa Sumbersalam, khususnya dalam aspek kegunaan dan kemudahan penggunaan.
### 2.2.3 Computer Vision dan Pengenalan Citra untuk Deteksi Penyakit Tanaman
**Computer Vision** adalah bidang kecerdasan buatan yang memungkinkan komputer untuk memahami dan menginterpretasi informasi visual dari dunia nyata. Dalam konteks pertanian, teknologi ini berperan penting dalam identifikasi penyakit tanaman melalui analisis visual terhadap gejala yang muncul pada daun, batang, atau bagian tanaman lainnya (Liu et al., 2021).
**Teknologi pengenalan citra** menggunakan algoritma deep learning, khususnya Convolutional Neural Networks (CNN), untuk mengekstrak fitur-fitur spesifik dari gambar dan membandingkannya dengan pola yang telah dipelajari untuk menghasilkan diagnosis yang akurat. Penelitian oleh Barbedo (2019) menunjukkan bahwa sistem otomatis berbasis computer vision dapat mencapai akurasi deteksi penyakit tanaman hingga 95% pada kondisi terkontrol.
**Gemini API** yang digunakan dalam penelitian ini merupakan implementasi advanced computer vision yang memanfaatkan Large Language Models (LLM) dengan kemampuan multimodal. API ini mampu menganalisis citra tanaman dan memberikan deskripsi diagnosis dalam format teks yang mudah dipahami petani, menggabungkan teknologi vision dengan natural language processing (Google AI, 2024).
### 2.2.4 Mobile Application Development dengan Flutter Framework
**Flutter** adalah framework open-source yang dikembangkan oleh Google untuk membangun aplikasi multi-platform dengan satu basis kode (single codebase). Framework ini menggunakan bahasa pemrograman Dart dan menawarkan performa tinggi serta antarmuka pengguna yang konsisten di berbagai platform (Google Flutter Team, 2023).
**Keunggulan Flutter** dalam pengembangan aplikasi pertanian meliputi:
- **Cross-platform compatibility**: Kemampuan deployment pada Android dan iOS secara bersamaan
- **Hot reload**: Fitur pengembangan yang mempercepat iterasi desain UI/UX
- **Native performance**: Kompilasi langsung ke kode native untuk performa optimal
- **Rich widget ecosystem**: Perpustakaan komponen UI yang ekstensif
- **Camera integration**: Dukungan native untuk akses kamera dan pemrosesan gambar
**Arsitektur aplikasi TaniSMART** mengimplementasikan pattern Model-View-ViewModel (MVVM) dengan Flutter sebagai presentation layer, yang memungkinkan separasi yang jelas antara business logic dan user interface. Hal ini mendukung maintainability dan scalability aplikasi sesuai dengan prinsip software engineering yang baik (Martin, 2017).
### 2.2.5 Backend as a Service (BaaS) dengan Supabase
**Backend as a Service (BaaS)** adalah model layanan cloud yang menyediakan infrastruktur backend siap pakai, memungkinkan pengembang fokus pada pengembangan frontend tanpa mengelola kompleksitas server-side infrastructure (Mell & Grance, 2011).
**Supabase** merupakan platform open-source yang menyediakan ekosistem backend lengkap sebagai alternatif modern untuk Firebase. Platform ini dibangun di atas PostgreSQL dan menawarkan fitur-fitur enterprise-grade seperti:
- **Real-time database**: Sinkronisasi data secara real-time menggunakan WebSocket

- **Auto-generated APIs**: RESTful dan GraphQL API yang ter-generate otomatis
- **Edge Functions**: Serverless functions untuk business logic kustom
- **File storage**: Penyimpanan file dengan CDN global
**Implementasi dalam TaniSMART** memanfaatkan Supabase untuk mengelola data pengguna, riwayat diagnosis, komunitas petani, dan analisis hasil panen. Arsitektur ini mendukung skalabilitas horizontal dan memastikan data consistency melalui ACID transactions yang disediakan PostgreSQL (Supabase Inc., 2024).
### 2.2.6 Human-Computer Interaction dalam Konteks Rural Technology Adoption
**Interaksi Manusia-Komputer (HCI)** dalam konteks rural memiliki karakteristik khusus yang harus dipertimbangkan dalam perancangan aplikasi untuk petani. Medhi et al. (2007) mengidentifikasi bahwa desain teknologi untuk pengguna rural memerlukan pendekatan yang berbeda dibandingkan urban users.
**Faktor-faktor kritis dalam rural HCI** meliputi:
- **Digital literacy variance**: Heterogenitas tingkat literasi digital yang memerlukan interface design yang adaptif
- **Contextual constraints**: Penggunaan dalam kondisi lapangan dengan keterbatasan konektivitas dan daya baterai
- **Cultural appropriateness**: Adaptasi terhadap norma sosial dan bahasa lokal
- **Economic accessibility**: Pertimbangan cost-effectiveness dan ROI untuk adopsi teknologi
**Prinsip Universal Design** yang diterapkan dalam TaniSMART mengacu pada framework dari Norman (2013) tentang design for everyone, dengan implementasi konkret berupa:
- **Visual affordances**: Penggunaan ikon dan metafora yang familiar dalam konteks pertanian
- **Progressive disclosure**: Penyajian informasi bertahap untuk menghindari cognitive overload
- **Error prevention & recovery**: Mekanisme feedback yang jelas dan opsi undo untuk kesalahan pengguna
- **Accessibility compliance**: Dukungan untuk berbagai kemampuan fisik dan kognitif
**Evaluasi usability** dalam penelitian ini mengadopsi framework dari Nielsen (2012) dengan metrik spesifik untuk konteks rural: effectiveness (task completion rate), efficiency (time on task), dan satisfaction (subjective user experience) yang diukur melalui post-interaction interviews dengan petani di Desa Sumbersalam.
## 2.3 Dataset dan Metodologi Pengumpulan Data
### 2.3.1 Dataset Citra Tanaman untuk Training dan Validation
**Dataset** dalam konteks machine learning untuk deteksi penyakit tanaman merupakan kumpulan terstruktur dari gambar tanaman yang telah dilabeli sesuai dengan kondisi kesehatan atau jenis penyakit yang diderita. Kualitas dan diversitas dataset secara langsung mempengaruhi akurasi model AI yang dihasilkan (Mohanty et al., 2016).
**Karakteristik dataset berkualitas** untuk deteksi penyakit tanaman meliputi:
- **Representativeness**: Mencakup variasi kondisi pencahayaan, sudut pengambilan, dan stadium penyakit
- **Balance**: Distribusi yang merata antar kelas untuk menghindari bias model
- **Scale adequacy**: Volume data yang cukup untuk generalization (minimal 1000 sampel per kelas)
- **Annotation quality**: Labeling yang akurat dan konsisten oleh domain experts
**Dalam implementasi TaniSMART**, penelitian ini menggunakan pendekatan hybrid dataset yang menggabungkan:
1. **Primary dataset**: Koleksi citra tanaman padi dari sawah Bapak Edi Puryanto di Desa Sumbersalam, Bondowoso
2. **Secondary dataset**: Repository publik seperti PlantVillage dan dataset yang dikurasi untuk tanaman tropis Indonesia
3. **Validation dataset**: Sampel khusus dari kondisi lapangan lokal untuk testing performance
**Metodologi pengumpulan primary dataset** mengikuti protokol standardized image acquisition dari Arsenovic et al. (2019), dengan spesifikasi teknis resolusi minimal 1024x1024 pixels, format JPEG/PNG, dan metadata lengkap termasuk timestamp, GPS coordinates, dan kondisi cuaca saat pengambilan.

## 3.10 Justifikasi Metodologi dan Limitasi Penelitian
### 3.10.1 Justifikasi Penggunaan Gemini API sebagai Knowledge Source
**Rasional akademis** penggunaan Gemini API sebagai sumber utama informasi penyakit tanaman dalam penelitian ini dapat dijelaskan melalui tiga aspek utama. Pertama, paradigma Design Science Research fokus pada pengembangan dan evaluasi artefak teknologi, bukan pada creation of new knowledge domain, sehingga penelitian ini mengevaluasi efektivitas implementasi teknologi AI existing (Gemini API) dalam konteks spesifik petani Indonesia. Kedua, penelitian ini termasuk kategori applied research yang menguji integrasi teknologi dalam solving real-world problems, bukan basic research yang membangun knowledge base dari scratch. Ketiga, dengan scope single case study di Desa Sumbersalam, penelitian ini tidak bertujuan untuk menghasilkan comprehensive database penyakit tanaman, melainkan menganalisis user acceptance dan usability aplikasi dalam konteks spesifik.
### 3.10.2 Limitasi dan Keterbatasan Penelitian
**Keterbatasan yang diakui** dalam penelitian ini meliputi tiga aspek utama. Pertama, dependency pada external API dimana akurasi diagnosis bergantung pada quality dan training data Gemini API, tidak ada kontrol terhadap algorithm dan knowledge base yang digunakan API, serta potential bias dari training data global yang mungkin tidak sepenuhnya representatif untuk kondisi Indonesia. Kedua, limited ground truth data karena penelitian ini tidak membangun dataset validasi yang comprehensive, dan validasi akurasi dilakukan melalui comparison dengan pengalaman empiris petani serta logical assessment hasil diagnosis. Ketiga, scope geografis terbatas dimana penelitian terbatas pada satu desa dengan karakteristik agroekosistem spesifik sehingga generalizability hasil mungkin terbatas untuk wilayah dengan kondisi berbeda.
### 3.10.3 Mitigasi Limitasi
**Strategi mitigasi** keterbatasan penelitian meliputi triangulasi dengan expert knowledge melalui cross-validation hasil Gemini API dengan pengalaman petani lokal serta consultation dengan penyuluh pertanian untuk logical validation diagnosis. Focus on user experience diterapkan dengan emphasis pada usability dan user acceptance sebagai primary metrics, serta evaluation utility aplikasi dari perspektif end-user bukan absolute accuracy. Transparent limitation acknowledgment dilakukan dengan clear documentation keterbatasan dalam hasil penelitian dan recommendation untuk future research dengan larger dataset dan validation.
### 3.10.4 Justifikasi Akademis
**Kontribusi akademis** penelitian ini terletak pada beberapa aspek penting. Pertama, implementation science yang menjelaskan bagaimana teknologi AI dapat diimplementasikan effectively dalam konteks rural Indonesia dengan segala keterbatasannya. Kedua, technology adoption yang menganalisis faktor-faktor yang mempengaruhi acceptance teknologi oleh petani tradisional dalam era digital. Ketiga, user-centered design yang mengembangkan design principles untuk aplikasi pertanian yang user-friendly untuk context rural dengan karakteristik unik. Keempat, case study methodology yang memberikan deep analysis adoption pattern dalam specific geographical dan cultural context Indonesia.
**Note untuk Defense**: Penelitian ini **tidak mengklaim** untuk menghasilkan new AI model atau comprehensive disease database, melainkan fokus pada **practical implementation** dan **user acceptance evaluation** existing technology dalam real-world context.
