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. - -## 2.1.4 State of The Art - Perbandingan Penelitian - -Untuk memberikan gambaran yang jelas tentang posisi penelitian ini dalam konteks akademis, berikut adalah perbandingan dengan penelitian-penelitian terdahulu yang relevan: - -| **Aspek** | **Ramesh et al.

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**.

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.

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.

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.

It has the potential to cause severe epidemic outbreaks, drastically affecting the volume of crop yield. The disease specifically targets rice plants (Oryza sativa), causing devastating damage to paddies. The organism causing the disease is a gram-negative, rod-shaped bacterium. Environmental factors like high humidity, temperature, and rain play a critical role in the spread of this disease. Despite its significant threat to global food security, there is a lack of comprehensive knowledge regarding the population dynamics and molecular biology of this pathogen.", - "symptoms": { - "Rotting smell": " Infected plants may produce a rotting smell due to the bacterial infection deteriorating the plant's health.", - "Wilting of leaves": " With disease progression, the leaves begin to wilt and dry out, causing them to look blighted.", - "Leaf discoloration": " The initial symptoms include water-soaked streaks forming on the leaves, turning into yellow to orange leaf lesions.", - "Leaf tip withering": " As the disease progresses, the leaf tips start withering and drying out, giving the plant a burnt appearance.", - "Reduction in yield": " The most severe outcome of bacterial blight of rice is a self-evident drop in the crop's yield, both due to loss of photosynthetic area and poor grain filling.", - "Grain discoloration": " The pathogen can invade the panicle, turning the grains reddish-brown or straw-colored with poor seed filling.", - "Greyish-white lesions": " The formation of greyish-white lesions (dead tissue) surrounded by yellow halo-like areas occur on the leaf blade and leaf sheath.", - "Lesions on leaf sheath": " The bacteria may penetrate the leaf sheath causing an irregularly-shaped, yellow to reddish, water-soaked lesion." - }, - "severity": "This particular plant disease is highly severe, often considered one of the most destructive for the affected crop. It can result in significant yield losses of up to 50%, sometimes completely wiping out fields under favorable conditions for disease development. It classically affects the plant at all growth stages, but infection during the booting stage causes the most drastic crop loss. It's not limited to a particular region or temperature, thus making it a ubiquitous threat to productions worldwide.", - "spreading": "The disease spreads primarily through infected seeds, water splash, and to some extent by wind-blown rain. Once initiated, the disease can spread rapidly under suitable climatic conditions, potentially impacting large swathes of a field within 2-3 weeks. Optimum conditions for its spread include high temperature (26-30°C), humidity, prolonged dew period, and leaf wetness. On the field, water-soaked lesions on leaves and leaf sheaths are indicators of the disease's presence, therefore, standing water enhances the disease progression. Moreover, it has been observed that the presence of free water, brought about by frequent rainfall or irrigation, plays a significant role in the disease spread.", - "treatment": { - "prevention": [ - "Field sanitation: Clean and sanitize your field equipment regularly to prevent the spreading of the bacteria.", - "Proper irrigation: Ensure right irrigation methods to prevent excess moisture, which encourages bacterial growth.", - "Remove infected plants: Promptly remove and destroy any infected plants to prevent disease spread.", - "Avoid overly dense planting: Give your plants enough space for air circulation to reduce disease transmission.", - "Monitor fields: Regularly check your fields for symptoms so that suitable treatments can be applied as soon as possible." - ], - "chemical treatment": [ - "Copper-based sprays: Apply copper-based fungicides to control the spread of the bacteria.", - "Antibiotics spray: Use tetracycline or streptomycin based sprays to inhibit bacterial growth.", - "Zinc and manganese supplements: Apply these key nutrients can help strengthen plants and make them more resistant to disease.", - "Dithiocarbamate sprays: Spray mancozeb or metiram fungicides to control bacterial blight.", - "Bordeaux mixture application: Use a mixture of copper sulfate and slaked lime for preventing bacterial blight." - ], - "biological treatment": [ - "Use resistant varieties: Choose and plant rice varieties that are genetically resistant to Xanthomonas oryzae.", - "Biocontrol agents usage: Employ potent biocontrol agents like Pseudomonas fluorescens and Bacillus subtilis to inhibit bacterial growth.", - "Phage therapy: Use bacteriophages, the viruses that infect bacteria, to control Xanthomonas oryzae.", - "Enhance plant's natural defense: Apply biofertilizers that can strengthen the plant's natural immune system.", - "Crop rotation: Regularly change your crops to prevent the build-up of harmful bacteria in your soil." - ] - }, - "language": "en", - "entity_id": "87d87c7ffbfcb31f" - }, - "scientific_name": "Xanthomonas oryzae pv. oryzae" - } - ] - }, - "crop": { - "suggestions": [ - { - "id": "528aa542ad1ff3fd", - "name": "rice", - "probability": 0.0022, - "similar_images": [ - { - "id": "7a2421ce6b1501577818e6b33194f92a163bf03f", - "url": "https://crop-health.ams3.cdn.digitaloceanspaces.com/similar_images/1/7a2/421ce6b1501577818e6b33194f92a163bf03f.jpeg", - "license_name": "CC BY-SA 4.0", - "license_url": "https://creativecommons.org/licenses/by-sa/4.0/", - "citation": "Juna Mardani", - "similarity": 0.12, - "url_small": "https://crop-health.ams3.cdn.digitaloceanspaces.com/similar_images/1/7a2/421ce6b1501577818e6b33194f92a163bf03f.small.jpeg" - }, - { - "id": "aa489a82745a06a61d01feb3137eebc1bb7d446b", - "url": "https://crop-health.ams3.cdn.digitaloceanspaces.com/similar_images/1/aa4/89a82745a06a61d01feb3137eebc1bb7d446b.jpeg", - "license_name": "CC BY-SA 4.0", - "license_url": "https://creativecommons.org/licenses/by-sa/4.0/", - "citation": "rento rukmawan", - "similarity": 0.102, - "url_small": "https://crop-health.ams3.cdn.digitaloceanspaces.com/similar_images/1/aa4/89a82745a06a61d01feb3137eebc1bb7d446b.small.jpeg" - } - ], - "details": { - "language": "en", - "entity_id": "528aa542ad1ff3fd" - }, - "scientific_name": "Oryza sativa" - } - ] - } - }, - "status": "COMPLETED", - "sla_compliant_client": true, - "sla_compliant_system": true, - "created": 1747031749.229281, - "completed": 1747031749.707866 -} \ No newline at end of file diff --git a/temp_scripts/setup_dart_project.bat b/temp_scripts/setup_dart_project.bat deleted file mode 100644 index da5724f..0000000 --- a/temp_scripts/setup_dart_project.bat +++ /dev/null @@ -1,25 +0,0 @@ -@echo off -echo Setting up Dart project for crop.health API testing... - -REM Create the project directory -mkdir crop_health_test -cd crop_health_test - -REM Create pubspec.yaml -echo name: crop_health_test > pubspec.yaml -echo description: A simple Dart app to test crop.health API >> pubspec.yaml -echo version: 1.0.0 >> pubspec.yaml -echo environment: >> pubspec.yaml -echo sdk: '^3.0.0' >> pubspec.yaml -echo dependencies: >> pubspec.yaml -echo http: ^1.1.0 >> pubspec.yaml - -REM Copy the Dart script -echo Copying Dart script... -copy ..\temp_scripts\fetch_crop_health.dart bin\main.dart - -REM Install dependencies -echo Installing dependencies... -dart pub get - -echo Setup complete!
