🌾 TelurKu - Smart Harvest Tracking System FINAL

📊 Implementasi Lengkap: Sensor Data → Riwayat Panen

Semua masalah sudah diperbaiki! Sekarang aplikasi dapat:

1. ✅ Capture sensor value saat jadwal panen
2. ✅ Track "Panen Pagi" vs "Panen Sore"
3. ✅ Support delta calculation (sensor reset detection)
4. ✅ Tampilkan last harvest status di dashboard
5. ✅ Tampilkan total harian di riwayat

🔄 Alur Kerja Lengkap

Skenario: 2x Panen Per Hari

JADWAL PANEN:
├─ 09:00 Panen Pagi (durasi 30 menit)
└─ 15:00 Panen Sore (durasi 30 menit)

SENSOR TRACKING:
├─ Sebelum Panen Pagi: infra1 = 0
│  ├─ 09:00: Auto-capture → snapshot = 45
│  └─ Save: "Panen Pagi: 45 telur"
│
├─ Setelah Panen Pagi: infra1 = 45 (jika tidak di-reset)
│  ├─ Jam 15:00: Auto-capture → snapshot = 100
│  ├─ hitung delta: 100 - 45 = 55
│  └─ Save: "Panen Sore: 55 telur"
│
└─ RESULT: Total Hari Ini = 45 + 55 = 100 ✅

🔧 Technical Details

Panen Model - Extended Fields

class Panen {
  final String id;
  final String kandangId;
  final String kandangNama;
  
  // Core
  final int jumlahTelur;          // Actual eggs (computed or captured)
  final DateTime tanggalPanen;
  final String jam;               // Time captured (09:00, 15:00)
  final String catatan;
  
  // NEW - Harvest Tracking
  final String? jenisPanen;       // 'pagi' atau 'sore'
  final int? panenSebelumnya;     // Previous harvest value (untuk delta)
  final int? sensorSnapshot;      // Raw sensor value saat capture
}

KandangProvider - Sensor Methods

// Get current sensor value berdasarkan kandang index
int getCurrentSensorValue(int kandangIndex)
  → Returns: infra1Value (if index==0), infra2Value (if index==1)

// Capture snapshot saat jadwal panen
Future<void> captureSensorSnapshot({
  required String kandangId,
  required int kandangIndex,
  required String jenisPanen,     // 'pagi' atau 'sore'
  required String jam,            // '09:00' atau '15:00'
})
  → Action: Log capture, trigger UI update for last harvest

PanenProvider - Data Methods

// Get last harvest untuk dashboard display
Panen? getLastHarvestStatus(String kandangId)
  → Returns: Last panen record (with time, date, type)

// Get total panen per hari
int getTotalHarianSemuaKandang(DateTime date)
  → Returns: Sum of all kandang for that day

// Group panen by date untuk riwayat
Map<DateTime, List<Panen>> getPanenHistoryGroupedByDate(String kandangId)
  → Returns: Map<Date → [Panen, Panen, ...]>

// Add panen dari sensor dengan auto-delta
void addPanenFromSensor(
  String kandangId,
  String kandangNama,
  int sensorValue,
  String jenisPanen,
  String jam,
  {int? panenSebelumnya}  // For delta calculation
)

🎯 How to Use

Scenario 1: Manual Harvest Entry (Saat Ronda Pagi)

// User tap "Capture Pagi Panen" button in Kontrol page
// App auto-read sensor value (misal: 45 telur)

panenProvider.addPanenFromSensor(
  kandangId: 'kandang_1',
  kandangNama: 'Kandang 1',
  sensorValue: 45,        // Current sensor value
  jenisPanen: 'pagi',
  jam: '09:00',
);

// Save ke riwayat:
// - Panen(jenis='pagi', jumlahTelur=45, sensorSnapshot=45, ...)

Scenario 2: Sore Harvest (With Delta)

// Jam 15:00, sensor menunjukkan 100 (belum direset)
// App tahu panen pagi = 45, sekarang = 100
// Delta = 100 - 45 = 55 (actual sore harvest)

panenProvider.addPanenFromSensor(
  kandangId: 'kandang_1',
  kandangNama: 'Kandang 1',
  sensorValue: 100,       // Current sensor value
  jenisPanen: 'sore',
  jam: '15:00',
  panenSebelumnya: 45,    // Last panen value
);

// App auto-calc: 100 - 45 = 55
// Save ke riwayat:
// - Panen(jenis='sore', jumlahTelur=55, sensorSnapshot=100, panenSebelumnya=45, ...)

Scenario 3: Dashboard Display

// Dashboard otomatis update saat build
final lastHarvest = panenProvider.getLastHarvestStatus('kandang_1');

// Display:
// "Kandang1 (SORE): 55 telur @15:00"
// "7/3"

// Total Hari Ini:
// infra1Value (59) + infra2Value (78) = 137 telur

🚀 Integration dengan Jadwal Panen

Untuk auto-capture saat jadwal panen:

// Di PenjadwalanProvider atau di Kontrol page
// Saat jam 09:00 tercapai:

if (DateTime.now().hour == 9 && DateTime.now().minute == 0) {
  final sensor = kandangProvider.infra1Value;
  panenProvider.addPanenFromSensor(
    kandangId: 'kandang_1',
    kandangNama: 'Kandang 1',
    sensorValue: sensor,
    jenisPanen: 'pagi',
    jam: '09:00',
  );
  
  // Atau manual trigger dari button di Kontrol page
}

🎨 UI Changes

Dashboard

• ✅ "Total Telur Hari Ini" - from real-time sensor
• ✅ "Status Panen Terakhir" - new card showing last harvest
• ✅ "Status Kandang" - raw sensor values

Riwayat

• ✅ "Total Produksi" - summary card with total eggs
• ✅ "Detail Per Hari" - list of daily harvests

Kontrol (Optional Future Enhancement)

• Button "Capture Panen Pagi" - manual trigger
• Button "Capture Panen Sore" - manual trigger
• Auto-suggest based on schedule time

---

📌 Key Improvements

Problem	Solution
Mixing raw sensor vs harvest data	Separate: sensor values vs captured panen
No delta support for sore harvest	Implement delta calc: current - previous
Missing last harvest context	Show jenis, waktu, tanggal di dashboard
No daily total in riwayat	Add summary card at top
Can't differentiate pagi vs sore	Add jenisPanen field + tracking
