Abstract

Studi ini menganalisis keberlanjutan angkutan umum penumpang dengan studi kasus di Kota Bogor. Tujuan studi ini adalah untuk menilai kondisi saat ini tingkat keberlanjutan angkutan umum penumpang berdasarkan dimensi ekonomi, sosial, lingkungan, dan kinerja pelayanan angkutan umum serta untuk mendapatkan atribut-atribut pengungkit (leverage attributes). Teknik Multidimensional Scaling dengan pengembangan aplikasi Rap-Rbptrans digunakan untuk menilai tingkat keberlanjutan angkutan umum penumpang dan mendapatkan atribut-atribut pengungkit (leverage attributes) tersebut. Hasil analisis terhadap Trayek 03 (Bubulak-Baranangsiang) menunjukkan bahwa kategori keberlanjutan dimensi ekonomi adalah tidak berkelanjutan; dimensi sosial cukup berkelanjutan; dimensi lingkungan kurang berkelanjutan; dimensi kinerja pelayanan kurang berkelanjutan; dan secara multidimensi adalah kurang berkelanjutan. Hasil analisis terhadap Trayek 01 (Baranangsiang-Ciawi) menunjukkan kategori keberlanjutan dimensi ekonomi adalah kurang berkelanjutan; dimensi sosial cukup berkelanjutan; dimensi lingkungan tidak berkelanjutan; dimensi kinerja pelayanan cukup berkelanjutan; dan secara multidimensi adalah kurang berkelanjutan. Secara agregat, hasil analisis menunjukkan kategori keberlanjutan dimensi ekonomi adalah kurang berkelanjutan; dimensi sosial cukup berkelanjutan; dimensi lingkungan kurang berkelanjutan; dimensi kinerja pelayanan cukup berkelanjutan; dan secara multidimensi adalah kurang berkelanjutan. Secara umum tingkat keberlanjutan angkutan umum penumpang tersebut adalah tergolong rendah atau belum berkelanjutan. Terdapat atribut-atribut pengungkit (leverage attributes) yang memerlukan intervensi dengan strategi kebijakan yang tepat agar menjadi lebih berkelanjutan.

Abstract

Pemanfaatan ekosistem mangrove untuk ekowisata sejalan dengan pergesaran wisatawan old tourism yaitu wisatawan yang datang dengan tujuan hanya untuk berwisata, menjadi new tourism yaitu wisatawan yang datang selain tujuan berwisata juga untuk pendidikan dan konservasi didalamnya. Taman ekowisata mangrove kacepi bertujuan meningkatkan pendapatan ekonomi masyarakat sekitar sebagai pengelola obyek wisata, yang pertama kali dibuka pada tahun 2019. Tujuan dari penelitian ini adalah untuk mengetahui jumlah jenis mangrove, kerapatan jenis mangrove, persentase kerapatan mangrove dan indeks kesesuaian wisata mangrove di taman ekowisata mangrove kacepi, Desa Kacepi. Metode yang digunakan pada penelitian adalah metode line transect untuk mengukur kerapatan dan mengamati jenis-jenis mangrove, metode Hemispherical Photography untuk menghitung persentase tutupan kanopi mangrove serta metode pembobotan/skoring untuk menentukkan nilai indeks kesesuaian wisata. Hasil penelitian ini menujukkan persentase tutupan kanopi adalah 73%, Jumlah jenis mangrove yang teramati adalah 5, kerapatan mangrove di TEMK adalah 17 ind/100m2, pasang surut air laut adalah 1,9 m, dan ketebalan mangrove adalah 183,45m. Secara keseluruhan, kesesuaian wisata mangrove di TEMK adalah 3,22 yang menunjukkan kesesuaian wisata mangrove di TEMK adalah cukup sesuai

Abstract

Rice food availability is increasingly challenged by paddy field conversion driven by socioeconomic development and land-use transformation. However, reductions in paddy field extent do not necessarily indicate decreased food availability, as agricultural systems may respond through intensification and productivity improvement. This study evaluated rice food availability resilience under paddy field land-use change in Sukabumi Regency, West Java, Indonesia, during 2000–2020 by integrating Landsat-based spatial analysis with agricultural production indicators. Paddy field dynamics were analyzed using multi-temporal Landsat imagery through Object-Based Image Analysis (OBIA) and Random Forest classification. Agricultural responses were assessed using harvested area, cropping intensity, productivity, rice production, and the Production Efficiency Index (PEI).The results showed that paddy field area declined from 71,641.44 ha in 2000 to 65,982.15 ha in 2020, representing a 7.9% reduction, with the largest decline occurring in rainfed paddy fields. Despite this reduction, rice production increased from 622,189 tons to 931,328 tons, supported by increases in harvested area, cropping intensity, and productivity, particularly within irrigated paddy field systems. The PEI increased from 8.68 to 14.12 ton ha⁻¹, indicating improved production efficiency relative to available land resources. These findings indicated that rice food availability resilience in Sukabumi Regency was supported by agricultural adaptation strategies, particularly through intensification and productivity enhancement rather than land expansion.Nevertheless, productivity improvements may not indefinitely compensate for continued paddy field conversion due to ecological and biophysical limitations. Integrating remote sensing-based land-use change analysis with agricultural performance indicators provides a useful framework for evaluating food availability resilience and supporting sustainable paddy field management.

Abstract

Background: Paddy is a staple food that is essential for global food security. Paddy land suitability evaluation is key to optimizing land resource management and productivity. Existing land evaluation techniques are manual and rigid, making them less representative of land physical data uncertainty and expert judgment reluctance. Most recent spatial decision support system and fuzzy logic-based techniques use one-dimensional models (membership) without considering expert hesitation.  Objective: This study aimed to develop a conceptual model for an Intelligent Spatial Decision Support System (ISDSS) for evaluating the suitability of paddy by integrating contextual user requirements with Soft System Methodology (SSM) and numerical examples.  Methods: This research methodology integrates SSM to identify problems and numerical examples based on Spherical Fuzzy Set (SFS) for land suitability assessment. The criteria weights are determined using the Spherical Fuzzy Analytical Hierarchy Process (SF-AHP), which represents each criterion through membership (μ), non-membership (ν), and hesitancy (π) degrees to capture hesitation in expert judgment. The findings of the weighing and evaluation were combined using Weighted Overlay Analysis (WOA) to produce a land suitability index.  Results: The SSM approach organizes complex and unstructured problems into a systematic conceptual framework. An example of an SFS calculation demonstrates computational feasibility based on expert validation, yielding an overall accuracy of 90% and a Cohen’s kappa coefficient of 0.861, indicating promising conceptual agreement.  Conclusion: The integration of SSM and numerical examples provides a conceptual foundation for developing ISDSS for evaluating paddy land suitability. Further research will focus on implementing a prototype to test spatial performance and the validity of results at the operational level.  Keywords: ISDSS, Numerical Example, Paddy Land Suitability, Spherical Fuzzy Set, SSM
