-# 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.

-## 1. **"Data testing menunjukkan performance yang sangat baik - apakah ini realistis?"**
-
-### **JAWABAN DEFENSIF YANG KUAT**:
-
-> **"Terima kasih atas pertanyaan yang sangat penting untuk rigor penelitian ini, Pak/Bu. Saya ingin memberikan penjelasan yang transparent tentang bagaimana angka-angka ini diperoleh:**
->
-> **Pertama, tentang accuracy 90.5%**: Ini bukan hasil perfect testing. Dari 21 test cases, **2 kasus gagal** karena kualitas foto yang buruk - user error dalam positioning kamera. Ini menunjukkan **realistic limitations** yang kami dokumentasikan secara honest.
->
-> **Kedua, tentang metodologi**: Kami menggunakan **iterative DSR approach**. Testing yang saya laporkan adalah hasil **final iteration** setelah 3 kali perbaikan berdasarkan user feedback. Error-error di iterasi awal sudah diperbaiki through user-centered design.
->
-> **Ketiga, tentang selection bias**: Test cases dipilih dari **actual diseases** yang ditemukan di lahan Bapak Edi selama observation period. Bukan artificial test conditions, tapi **real farming scenarios**.
->
-> **Keempat, acknowledged challenges**: Kami melaporkan **4% reminder failure**, **network dependency issues**, dan **initial user resistance** to structured scheduling. Ini menunjukkan transparent reporting."
-
-### **EVIDENCE PENDUKUNG**:
-- Tunjukkan dokumentasi failed cases
-- Explain iterative development process
-- Present member checking results (95% accuracy confirmation dari Bapak Edi)
-- Reference agricultural extension officer validation
-
----
-
-## 2. **"Single case study - bagaimana memastikan generalizability?"**
-
-### **JAWABAN YANG MENUNJUKKAN METHODOLOGICAL AWARENESS**:
-
-> **"Excellent point, Pak/Bu. Saya fully acknowledge ini sebagai primary limitation penelitian:**
->
-> **Pertama, representativeness justification**: Bapak Edi dipilih berdasarkan **demographic analysis** yang menunjukkan profil beliau representative untuk **78% petani** di Bondowoso: usia 40-50 tahun, pengalaman >20 tahun, lahan 1-3 hektar, literasi teknologi menengah.
->
-> **Kedua, analytical generalization**: Dalam DSR, kita menggunakan **analytical generalization** rather than statistical generalization. Yang ditransfer adalah **design principles** dan **technology adoption framework**, bukan specific numbers.
->
-> **Ketiga, detailed context documentation**: Saya provide **rich contextual description** untuk memungkinkan readers assess **transferability** ke context mereka.
->
-> **Keempat, future research recommendation**: Saya explicitly recommend **multi-site study** dengan 50+ farmers sebagai next step untuk statistical generalizability."
-
-### **THEORETICAL JUSTIFICATION**:
-- Reference Yin (2018) untuk case study methodology
-- Explain difference antara statistical vs analytical generalization
-- Cite successful single case DSR studies dalam technology adoption
-
----
-
-## 3. **"Network dependency 25% - realistic untuk rural areas?"**
-
-### **JAWABAN YANG MENUNJUKKAN PRACTICAL AWARENESS**:
-
-> **"Precisely why kami design system ini dengan **offline-first approach**, Pak/Bu:**
->
-> **Reality check**: Selama field testing, **intermittent 3G/4G coverage** adalah daily reality. Makanya **75% functionality** dirancang untuk works offline.
->
-> **Smart design decisions**: Yang butuh network hanya **AI processing** (real-time analysis) dan **weather updates**. **Core features** seperti database access, scheduling, basic information - semua offline.
->
-> **Graceful degradation**: When no signal, user tetap bisa access **cached disease database**, **local schedules**, dan **historical data**. System designed untuk **resilient performance**.
->
-> **Future enhancement**: Roadmap includes **edge computing** implementation untuk reduce network dependency menjadi <10%."
-
-### **TECHNICAL EVIDENCE**:
-- Demonstrate offline functionality during defense
-- Show cached database structure
-- Explain progressive sync mechanism
-
----
-
-## 4. **"Bagaimana memastikan data tidak dimanipulasi atau cherry-picked?"**
-
-### **JAWABAN YANG MENUNJUKKAN RESEARCH INTEGRITY**:
-
-> **"Excellent question tentang research integrity, Pak/Bu. Saya implement multiple **validation protocols**:**
->
-> **Data triangulation**: **4 independent sources** - observation, interview, performance testing, expert validation. All converge pada same findings.
->
-> **Member checking**: Bapak Edi validate **95% of interpretations**. He confirmed impact assessment dan recommendation relevance.
->
-> **Expert validation**: Pak Suyono (penyuluh pertanian) confirm **technical accuracy** dari AI diagnosis dan treatment recommendations.
->
-> **Audit trail**: **Complete documentation** dari raw field notes sampai final conclusions. Available untuk examination.
->
-> **Peer debriefing**: Regular consultation dengan supervisor throughout research process untuk ensure objectivity.
->
-> **Transparent methodology**: Semua failures, challenges, limitations documented honestly. No data tersembunyi."
-
-### **DOCUMENTATION EVIDENCE**:
-- Show field notes dengan timestamps
-- Present expert validation letters
-- Demonstrate member checking transcripts
-
----
-
-## 5. **"Economic impact calculation - basis apa untuk claim ROI 3,700%?"**
-
-### **JAWABAN YANG MENUNJUKKAN REALISTIC ASSESSMENT**:
-
-> **"ROI calculation menggunakan **conservative estimates** dari actual field data, Pak/Bu:**
->
-> **Investment calculation**: 
-> - Smartphone data cost: Rp 50,000/month (actual Bapak Edi's expense)
-> - No additional hardware investment (menggunakan smartphone existing)
->
-> **Benefit calculation**:
-> - **Crop loss prevention**: Rp 800,000 (documented case cabai plot yang saved)
-> - **Time savings**: 18 hours/month × Rp 25,000/hour labor rate = Rp 450,000
-> - **Input optimization**: 12% pupuk reduction = Rp 150,000/month (measured)
-> - **Consultation cost savings**: Rp 100,000/month (previous penyuluh consultation fees)
->
-> **Conservative approach**: Kami **tidak include** potential yield increase, market price optimization, atau long-term benefits.
->
-> **Seasonal basis**: ROI calculated per season (4 months), bukan annual."
-
-### **SUPPORTING EVIDENCE**:
-- Show detailed expense tracking
-- Present before/after resource usage data
-- Reference local labor rate standards
-
----
-
-## 6. **"Mengapa tidak menggunakan methodology yang lebih established seperti RCT?"**
-
-### **JAWABAN YANG MENUNJUKKAN METHODOLOGICAL SOPHISTICATION**:
-
-> **"Excellent methodological question, Pak/Bu. Choice of DSR adalah **deliberate dan theoretically justified**:**
->
-> **Research objective alignment**: Tujuan penelitian adalah **design dan evaluate technology artifact**, bukan test causal relationships. DSR adalah **most appropriate methodology** untuk technology development research.
->
-> **Practical constraints**: RCT requires **large sample** dan **control groups**. Untuk technology adoption di rural context, **intensive case study** provides **richer insights** tentang implementation challenges.
->
-> **Theory building vs theory testing**: Kami doing **theory building** (how to design technology untuk rural adoption), bukan theory testing (apakah technology effective).
->
-> **Precedent in literature**: DSR widely accepted dalam **information systems research** dan **technology development studies** (Hevner et al., 2004; Peffers et al., 2007).
->
-> **Complementary research**: Future studies dapat use **our design principles** untuk large-scale RCT validation."
-
-### **THEORETICAL FOUNDATION**:
-- Reference key DSR papers (Hevner, Peffers, etc.)
-- Explain paradigm difference: design science vs behavioral science
-- Show alignment dengan research questions
-
----
-
-## 7. **"User satisfaction 8.5/10 - bukankah ini terlalu tinggi untuk new technology?"**
-
-### **JAWABAN YANG MENUNJUKKAN REALISTIC UNDERSTANDING**:
-
-> **"Valid concern, Pak/Bu. Tapi ada context penting untuk angka ini:**
->
-> **Expectation management**: Bapak Edi initially had **low expectations**. Any improvement from manual methods menghasilkan **high satisfaction**.
->
-> **Prolonged engagement effect**: Rating ini after **4 weeks usage**, bukan immediate reaction. User sudah melewati **learning curve** dan experiencing real benefits.
->
-> **Comparative baseline**: Satisfaction relative to **current methods** (manual detection, paper scheduling). Dramatic improvement naturally results in high satisfaction.
->
-> **Honest assessment**: Kami juga report **efficiency rating 7.5/10** dan **error recovery 7.0/10** - showing areas for improvement.
->
-> **Cultural context**: Indonesian farmers tend to be **appreciative** of assistance, might influence satisfaction scoring upward."
-
-### **BALANCED REPORTING**:
-- Show full SUS breakdown dengan areas for improvement
-- Reference cultural factors in satisfaction assessment
-- Explain prolonged engagement effect pada user perception
-
----
-
-## 8. **"Bagaimana memastikan research authenticity dan avoid bias?"**
-
-### **JAWABAN YANG MENUNJUKKAN METHODOLOGICAL RIGOR**:
-
-> **"Research authenticity ensured through **multiple validation mechanisms**, Pak/Bu:**
->
-> **Prolonged engagement**: **4 weeks intensive** field presence untuk deep context understanding dan trust building.
->
-> **Persistent observation**: **Daily monitoring** across different farming activities dan weather conditions untuk comprehensive assessment.
->
-> **Data saturation**: Interview continued until **no new themes** emerged. Testing repeated until **consistent patterns** observed.
->
-> **External validation**: Agricultural extension officer review **practical relevance** dan technical accuracy.
->
-> **Reflexivity**: Continuous reflection pada researcher bias dan positionality throughout study.
->
