+<VirtualHost *:80>
+    ServerName system.local
+    DocumentRoot /var/www/project
+    <Directory /var/www/project>
+        AllowOverride All
+        Require all granted
+    </Directory>
+</VirtualHost>
+```
+
+### Using Nginx
+```nginx
+server {
+    listen 80;
+    server_name system.local;
+    root /var/www/project;
+    
+    location ~\.php$ {
+        fastcgi_pass 127.0.0.1:9000;
+        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+        include fastcgi_params;
+    }
+}
+```
+
+## 📊 Performance
+
+- **Page Load:** < 3 seconds (on 10 Mbps connection)
+- **API Response:** < 500ms for most endpoints
+- **Map Rendering:** Real-time interactivity
+- **Scoring Computation:** < 1 second for 100 households
+
+## 🛠️ Development Guide
+
+### Adding New Endpoint
+1. Create new file in `/api/` folder: `your_endpoint.php`
+2. Include `config.php` for database access
+3. Use `requireLogin()` or `requireRole()` for access control
+4. Return JSON response
+
+Example:
+```php
+<?php
+header('Content-Type: application/json');
+require_once 'config.php';
+
+requireRole(['Admin', 'Petugas']);
+
+// Your code here
+
+die(json_encode(['success' => true, 'data' => $result]));
+?>
+```
+
+### Modifying Frontend
+1. Edit `js/app.js` for logic changes
+2. Edit `css/style.css` for styling
+3. Edit `index.html` for structure/layout
+4. Refresh browser to see changes (no build required)
+
+## 🐛 Troubleshooting
+
+### Login Issues
+- Verify email: `admin@system.local`
+- Verify password: `admin123`
+- Check browser cookies are enabled
+- Clear cache and try again
+
+### Map Not Loading
+- Check browser console for errors (F12)
+- Verify internet connection (for Leaflet CDN)
+- Try refreshing page
+
+### Database Issues
+- Ensure `/db/` folder has write permissions
+- Check PHP error logs
+- Delete `db/markers.db` to reset (will lose data)
+
+### Performance Issues
+- Check browser performance (F12 > Performance tab)
+- Monitor server CPU/memory usage
+- Consider adding pagination for large datasets
+
+## 📝 Changelog

+LAPORAN RANCANGAN SISTEM GEOSPASIAL UNTUK PENGENTASAN KEMISKINAN
+Studi Kasus: Integrasi Data Masjid, Poin Berkebutuhan, dan Wilayah Administratif Pontianak
+
+
+ABSTRAK
+Kemiskinan merupakan persoalan multidimensi yang memerlukan intervensi terarah berbasis bukti. Laporan ini merancang sistem geospasial untuk mendukung pengentasan kemiskinan pada tingkat kota melalui integrasi titik layanan komunitas (masjid), titik rumah tangga/penerima berkebutuhan, data aksesibilitas jalan, dan batas wilayah administratif. Fokus utama laporan adalah analisis pihak-pihak yang terlibat serta rancangan atribut data yang dibutuhkan oleh masing-masing pihak agar proses perencanaan, verifikasi, penyaluran bantuan, dan evaluasi program dapat berjalan terukur. Rancangan dilengkapi kerangka kuantitatif berupa skor kerentanan, skor aksesibilitas, skor prioritas intervensi, dan indikator kinerja program. Hasil rancangan menunjukkan bahwa pendekatan geospasial dapat mengurangi salah sasaran, mempercepat verifikasi lapangan, dan meningkatkan transparansi lintas pemangku kepentingan.
+
+Kata kunci: kemiskinan multidimensi, geospasial, targeting bantuan sosial, Pontianak, manajemen data, evaluasi kuantitatif.
+
+
+1. PENDAHULUAN
+1.1 Latar Belakang
+Program pengentasan kemiskinan sering menghadapi tiga masalah utama: (1) ketidaktepatan sasaran rumah tangga prioritas, (2) keterlambatan verifikasi data lapangan, dan (3) lemahnya evaluasi spasial dampak program. Pada konteks perkotaan, masalah tersebut semakin kompleks karena heterogenitas kondisi sosial-ekonomi dan disparitas akses layanan antarwilayah.
+
+Sistem geospasial memberi peluang untuk menggabungkan dimensi lokasi (where), kebutuhan (what), aktor (who), waktu (when), dan intervensi (how much). Dalam studi kasus ini, titik masjid diposisikan sebagai simpul komunitas untuk menjangkau titik berkebutuhan dalam radius layanan tertentu, kemudian dipadukan dengan batas wilayah administratif dan indikator kepadatan/infrastruktur.
+
+1.2 Rumusan Masalah
+1. Data atribut apa yang diperlukan masing-masing pihak agar pengentasan kemiskinan berbasis geospasial dapat berjalan efektif?
+2. Bagaimana merancang atribut data yang konsisten untuk kebutuhan operasional lapangan dan kebutuhan analitik kebijakan?
+3. Bagaimana membangun kerangka kuantitatif formal agar prioritas bantuan dapat ditetapkan secara objektif dan terukur?
+
+1.3 Tujuan
+1. Menyusun rancangan sistem data geospasial untuk pengentasan kemiskinan berbasis komunitas.
+2. Menganalisis pihak terlibat dan kebutuhan informasi spesifik per pihak.
+3. Merancang atribut data inti, pendukung, dan strategis untuk setiap pihak.
+4. Menyusun model kuantitatif formal untuk penetapan prioritas intervensi dan evaluasi hasil.
+
+1.4 Batasan
+1. Laporan berfokus pada rancangan data dan tata kelola informasi.
+2. Laporan tidak membahas implementasi penuh dashboard baru.
+3. Rancangan mengacu pada konteks data yang sudah tersedia pada sistem (masjid, poin berkebutuhan, jalan, wilayah administratif, statistik area).
+
+
+2. LANDASAN KONSEPTUAL
+2.1 Kemiskinan Multidimensi
+Kemiskinan tidak cukup diukur oleh pendapatan semata, melainkan juga keterbatasan akses pendidikan, kesehatan, perumahan layak, infrastruktur dasar, dan perlindungan sosial. Karena itu, desain data harus mendukung indikator multidimensi agar keputusan bantuan lebih adil.
+
+2.2 Peran Data Geospasial
+Data geospasial memungkinkan:
+1. Pemetaan konsentrasi kerentanan antarwilayah.
+2. Analisis jarak dan aksesibilitas terhadap titik layanan.
+3. Verifikasi konsistensi lokasi terhadap wilayah administrasi.
+4. Monitoring cakupan intervensi dari waktu ke waktu.
+
+2.3 Prinsip Tata Kelola Data
+1. Akurat: data tervalidasi, dapat ditelusuri sumbernya.
+2. Terkini: pembaruan periodik dengan jadwal jelas.
+3. Konsisten: definisi atribut dan satuan baku.
+4. Aman: perlindungan data pribadi (khusus NIK/identitas sensitif).
+5. Akuntabel: jelas siapa input, verifikasi, dan persetujuan.
+
+
+3. PIHAK TERLIBAT DAN PERAN KEPUTUSAN
+Bagian ini memetakan pemangku kepentingan utama dan jenis keputusan yang didukung data.
+
+3.1 Pemerintah Daerah (Pemda/Bappeda)
+Peran:
+1. Menetapkan prioritas wilayah intervensi.
+2. Menyusun alokasi anggaran lintas kecamatan/kelurahan.
+3. Mengawasi kinerja program secara makro.
+
+Keputusan berbasis data:
+1. Wilayah prioritas tinggi untuk penambahan program.
+2. Penyesuaian anggaran berdasarkan beban kerentanan.
+3. Evaluasi efektivitas kebijakan antarperiode.
+
+3.2 Dinas Sosial
+Peran:
+1. Menetapkan rumah tangga sasaran.
+2. Mengelola program bantuan (jenis, nilai, jadwal, frekuensi).
+3. Menjamin verifikasi administrasi penerima.
+
+Keputusan berbasis data:
+1. Daftar penerima prioritas dan waiting list.
+2. Jenis bantuan paling relevan per rumah tangga.
+3. Jadwal distribusi dan monitoring kepatuhan.
+
+3.3 Kelurahan/RT/RW
+Peran:
+1. Verifikasi kondisi faktual rumah tangga.
+2. Validasi domisili, komposisi keluarga, kondisi hunian.
+3. Pelaporan perubahan cepat (migrasi, bencana, kehilangan pekerjaan).
+
+Keputusan berbasis data:
+1. Validasi kelayakan calon penerima.
+2. Rekomendasi perubahan status prioritas.
+3. Eskalasi kasus mendesak ke Dinas Sosial.
+
+3.4 Pengelola Masjid (Simpul Komunitas)
+Peran:
+1. Menjadi titik koordinasi bantuan berbasis radius layanan.
+2. Menyediakan informasi kebutuhan lokal berbasis komunitas.
+3. Memantau sebaran penerima dalam cakupan layanan masjid.
+
+Keputusan berbasis data:
+1. Penjadwalan distribusi bantuan komunitas.
+2. Penetapan relawan dan wilayah jangkauan.
+3. Rujukan kasus rentan ke dinas terkait.
+
+3.5 Petugas Lapangan/Enumerator
+Peran:
+1. Input geolokasi dan atribut rumah tangga.
+2. Verifikasi berkala kondisi sosial-ekonomi.
+3. Dokumentasi bukti lapangan (foto, catatan observasi, tanggal kunjungan).
+
+Keputusan berbasis data:
+1. Konfirmasi valid/tidak valid data calon penerima.
+2. Klasifikasi tingkat kerentanan lapangan.
+3. Rekomendasi tindak lanjut cepat.
+
+3.6 Lembaga Penyalur Bantuan (Pemerintah/CSR/NGO/Baznas)
+Peran:
+1. Menyalurkan bantuan sesuai daftar terverifikasi.
+2. Mencatat nilai bantuan, jenis bantuan, waktu penyaluran.
+3. Memonitor coverage dan gap distribusi.

+
+
+6. KERANGKA KUANTITATIF FORMAL
+6.1 Normalisasi Nilai
+Semua indikator dinormalisasi ke skala 0 sampai 1 agar dapat digabungkan.
+
+Rumus normalisasi min-max:
+X_norm = (X - X_min) / (X_max - X_min)
+
+Untuk indikator negatif (semakin besar semakin buruk), gunakan:
+X_norm_neg = 1 - ((X - X_min) / (X_max - X_min))
+
+6.2 Skor Kerentanan Rumah Tangga (SKR)
+SKR = 0.25*I + 0.20*E + 0.15*D + 0.15*H + 0.15*A + 0.10*S
+
+Keterangan komponen:
+I: Deprivasi pendapatan.
+E: Kerentanan ketenagakerjaan.
+D: Beban tanggungan (anak, lansia, disabilitas).
+H: Kualitas hunian dan sanitasi.
+A: Akses layanan dasar (air, listrik, kesehatan, pendidikan).
+S: Riwayat guncangan sosial-ekonomi.
+
+Rentang SKR: 0 sampai 1.
+
+6.3 Skor Aksesibilitas Geospasial (SAG)
+SAG = 0.40*J + 0.35*R + 0.25*T
+
+J: Jarak ke titik layanan bantuan (dinormalisasi negatif).
+R: Kualitas akses jalan (berdasarkan condition_status dan road_density lokal).
+T: Estimasi waktu tempuh layanan.
+
+Interpretasi:
+Nilai lebih tinggi = aksesibilitas lebih baik.
+
+6.4 Skor Prioritas Intervensi (SPI)
+SPI = 0.60*SKR + 0.30*(1 - SAG) + 0.10*K
+
+K: Faktor kejadian guncangan terbaru (0 atau 1, atau skala 0 sampai 1).
+
+Klasifikasi:
+1. SPI >= 0.75: Prioritas sangat tinggi.
+2. 0.60 <= SPI < 0.75: Prioritas tinggi.
+3. 0.45 <= SPI < 0.60: Prioritas menengah.
+4. SPI < 0.45: Prioritas rendah.
+
+6.5 Indikator Kinerja Program (IKP)
+1. Coverage Ratio (CR) = jumlah RT terbantu / jumlah RT prioritas.
+2. Targeting Precision (TP) = RT sasaran benar / total RT yang menerima bantuan.
+3. On-Time Delivery (OTD) = bantuan tepat waktu / total bantuan tersalurkan.
+4. Outcome Improvement Rate (OIR) = RT dengan delta outcome positif / total RT yang dievaluasi.
+
+
+7. PEMETAAN EXISTING DATA VS GAP DATA
+7.1 Atribut yang sudah tersedia
+1. Titik masjid dan radius layanan.
+2. Titik berkebutuhan beserta relasi ke masjid.
+3. Batas wilayah administratif (kecamatan/kota).
+4. Statistik area (kepadatan penduduk/jalan/kerusakan jalan).
+5. Data infrastruktur jalan (jenis dan kondisi).
+
+7.2 Atribut yang belum tersedia (gap utama)
+1. Profil sosial-ekonomi rumah tangga detail.
+2. Status kemiskinan multidimensi tingkat rumah tangga.
+3. Riwayat bantuan per rumah tangga (jenis, nilai, frekuensi).
+4. Status verifikasi, bukti lapangan, dan confidence score.
+5. Data outcome pasca-bantuan (30 hari, 90 hari, semester).
+6. Data pengaduan dan kepuasan layanan.
+
+7.3 Dampak jika gap tidak ditutup
+1. Penetapan sasaran rentan bias.
+2. Sulit membedakan rumah tangga prioritas antarwilayah.
+3. Evaluasi program hanya berhenti pada output, bukan outcome.
+4. Risiko kebocoran dan duplikasi bantuan meningkat.
+
+
+8. TAHAP IMPLEMENTASI DATA (REKOMENDASI)
+Tahap 1 (0-3 bulan): Pendataan dasar dan verifikasi spasial
+1. Tambah atribut rumah tangga inti.
+2. Validasi koordinat dan area administrasi.
+3. Integrasi relasi RT-ke-masjid dalam radius layanan.
+
+Tahap 2 (3-6 bulan): Operasional penyaluran dan audit
+1. Tambah modul riwayat bantuan dan status distribusi.
+2. Tambah atribut verifikasi lapangan dan confidence score.
+3. Jalankan dashboard monitoring coverage dan ketepatan sasaran.
+
+Tahap 3 (6-12 bulan): Evaluasi outcome dan optimasi kebijakan
+1. Tambah atribut outcome 30/90 hari.
+2. Hitung IKP rutin per wilayah.
+3. Lakukan evaluasi pembobotan SPI dan revisi kebijakan.
+
+
+9. RISIKO DAN MITIGASI
+9.1 Risiko kualitas data
+Risiko: data tidak mutakhir atau tidak konsisten antarpetugas.
+Mitigasi:
+1. SOP input baku.
+2. Validasi otomatis pada rentang nilai.
+3. Audit sampel bulanan.
+
+9.2 Risiko privasi data
+Risiko: kebocoran data identitas sensitif.
+Mitigasi:
+1. Simpan identitas sensitif dalam bentuk hash/token.
+2. Batasi akses berbasis peran.
+3. Log akses dan log perubahan data.
+
+9.3 Risiko bias penargetan
+Risiko: ketergantungan pada satu indikator.
+Mitigasi:
+1. Gunakan indikator multidimensi.
+2. Verifikasi silang RT/RW dan petugas lapangan.
+3. Review bobot skor secara periodik.
+
+
+10. KESIMPULAN
+Rancangan sistem geospasial pengentasan kemiskinan pada studi kasus ini menempatkan data sebagai fondasi keputusan lintas aktor. Dengan merinci atribut per pihak, sistem dapat menjembatani kebutuhan operasional lapangan dan kebutuhan strategis kebijakan. Kerangka kuantitatif yang diusulkan (SKR, SAG, SPI, IKP) memberi landasan formal untuk prioritisasi intervensi, peningkatan akurasi sasaran, dan evaluasi hasil program secara objektif.
+
+Rekomendasi utama:
+1. Prioritaskan penutupan gap atribut rumah tangga dan riwayat bantuan.
+2. Terapkan verifikasi spasial dan audit data berkala.
+3. Gunakan indikator outcome agar kebijakan tidak hanya mengejar jumlah bantuan, tetapi juga perubahan kesejahteraan nyata.
