Sikturah — Sustainable Forestry Multi-business Optimization

About the ResearchTentang Penelitian

Indonesia's Forestry Multi-business policy (Law No. 11/2020, Government Regulation No. 23/2021, MoEF Regulation No. 8/2021) shifts production-forest management from a single-timber regime toward an integrated business portfolio. This research answers the key question: how should combinations of forestry businesses be selected and scheduled on every compartment so that ecological, economic, and social sustainability are achieved simultaneously? Kebijakan Multi Usaha Kehutanan (UU No. 11/2020, PP No. 23/2021, Permen LHK No. 8/2021) menggeser pengelolaan hutan produksi dari rezim kayu tunggal menuju portofolio usaha terintegrasi. Penelitian ini menjawab pertanyaan kuncinya: bagaimana memilih dan menjadwalkan kombinasi usaha kehutanan pada setiap petak agar kelestarian ekologi, ekonomi, dan sosial tercapai sekaligus?

Study 1 — Indicator FrameworkStudi 1 — Kerangka Indikator

45 strong-sustainability indicators across ten dimensions; 24 imperative indicators classified through ISM-MICMAC; hybrid AHP weighting; BOCR scenario assessment in three forest management units (KPH). 45 indikator strong sustainability lintas sepuluh dimensi; klasifikasi 24 indikator keharusan melalui ISM-MICMAC; pembobotan AHP hybrid; penilaian skenario BOCR pada tiga KPH.

Study 2 — Simulation & Dynamic BOCRStudi 2 — Simulasi & BOCR Dinamis

A 30-year stand- and business-dynamics simulation model; per-period BOCR scores with discounted, worst-period, and threshold-violation metrics. Model simulasi dinamika tegakan dan usaha berhorizon 30 tahun; skor BOCR per periode dengan metrik terdiskonto, periode terburuk, dan pelanggaran ambang.

Study 3 — Schedule OptimizationStudi 3 — Optimasi Penjadwalan

A multi-objective genetic algorithm (constrained NSGA-II) builds per-compartment MUK option schedules that optimize the three sustainability pillars simultaneously under imperative-indicator thresholds. Algoritma genetika multi-tujuan (constrained NSGA-II) menyusun jadwal opsi MUK per petak yang mengoptimalkan tiga pilar kelestarian sekaligus di bawah ambang indikator keharusan.

What the Application DoesApa yang Dilakukan Aplikasi

The Sikturah application accepts planning data in the Excel format KPH planners already know, then runs the entire analysis engine on the server. Aplikasi Sikturah menerima data perencanaan dalam format Excel yang sudah dikenal para perencana KPH, lalu menjalankan seluruh mesin analisis di server.

Catalog of 100 MUK OptionsKatalog 100 Opsi MUK

Ten planting patterns × ten species/commodities — from teak monoculture to coffee agroforestry and ecotourism–environmental-services overlays — complete with rotation, minimum harvest age, and site suitability. Sepuluh pola tanam × sepuluh jenis/komoditas — dari monokultur jati hingga agroforestri kopi dan overlay wisata-jasa lingkungan — lengkap dengan rotasi, umur panen minimum, dan kesesuaian tapak.

30-Year Simulation per CompartmentSimulasi 30 Tahun per Petak

Installed options, cutting decisions, stand age, and managed area are simulated annually for every compartment of the sustainability unit. Dinamika opsi terpasang, keputusan tebang, umur tegakan, dan luas kelola disimulasikan tahunan untuk setiap petak unit kelestarian.

BOCR AssessmentPenilaian BOCR

Every scenario is scored on four merits — Benefits, Opportunities, Costs, Risks — with indicator weights from an expert panel. Setiap skenario dinilai pada empat merit — Benefits, Opportunities, Costs, Risks — dengan bobot indikator hasil panel pakar.

NSGA-II OptimizationOptimasi NSGA-II

Thousands of schedule alternatives are evaluated per second; the result is a set of best-compromise (Pareto) solutions with per-compartment MUK schedules, downloadable back as Excel. Ribuan alternatif jadwal dievaluasi per detik; hasilnya himpunan solusi terbaik (Pareto) beserta jadwal opsi MUK per petak yang siap diunduh kembali sebagai Excel.
