Abstract

Gerakan tanah merupakan suatu peristiwa alam yang pada saat ini frekuensi kejadiannya semakin meningkat. Penelitian ini bertujuan untuk (1). Memetakan daerah rawan bencana gerakan tanah di Kabupaten Sinjai (2). Mengevaluasi arahan struktur dan pola ruang berdasarkan sebaran daerah rawan bencana gerakan tanah di Kabupaten Sinjai. Penelitian ini dilaksanakan di Kabupaten Sinjai Propinsi Sulawesi Selatan, periode bulan Agustus-September 2012. Penelitian ini merupakan penelitian deskriptif dengan melakukan analisis dokumen terhadap Rencana Tata Ruang Wilayah (RTRW), observasi dan wawancara. Analisis data menggunakan metode overlay (tumpang tindih) dengan Sistem Informasi Geografis (SIG) terhadap parameter kemiringan lereng, geologi, struktur geologi, curah hujan penggunaan lahan dan infrastruktur menghasilkan sebaran zonasi kerawanan gerakan tanah, serta overlay peta rawan bencana gerakan tanah  dengan peta rencana tata ruang wilayah untuk menghasilkan rekomendasi perencanaan pengembangan wilayah. Hasil penelitian menunjukkan bahwa daerah penelitian terbagi atas empat zona kerentanan gerakan tanah, yaitu (1) Zona kerentanan gerakan tanah tinggi, (2) Zona kerentanan gerakan tanah menengah, (3) zona kerentanan gerakan tanah rendah dan (4) Zona kerentanan gerakan tanah sangat rendah. Sedangkan evaluasi pemanfaatan ruang  terdiri atas daerah yang sudah sesuai dan daerah yang belum sesuai peruntukkannya berdasarkan sebaran daerah rawan gerakan tanah. Kesimpulannya adalah Pada wilayah Kabupaten Sinjai  terdapat empat zona kerentanan tanah yaitu zona kerentanan tinggi seluas 1352 Ha (1,6% dari luas wilayah kabupaten) lokasi dominan yaitu : Tompobullu, Bontokatute, Bijinangka, Gunung Perak, Pattongko, Kompang,  zona kerentanan menengah seluas  37403 Ha (45,7% dari luas wilayah kabupaten) lokasi dominan yaitu: Bullupoddo, Barambang, Barania, Bonto, Bontolempangang, Lamatti rilau, zona kerentanan rendah seluas 43055 Ha (52,5% dari luas wilayah kabupaten) lokasi dominan yaitu : Biringere, Kampala, dan zona kerentanan sangat rendah seluas 186 Ha (0,2% dari luas wilayah kabupaten) lokasi dominan yaitu: Bongki, Lappa.

Abstract

Land use conversion affects the water management of a watershed, leading to flooding, erosion, and sedimentation. Tallo Watershed located in South Sulawesi is considered critical due to frequent flooding. This study aims to change the land use of the Tallo River Watershed (DAS) and its influence on watershed performance in terms of water management aspects. The methods used include spatial analysis with supervised classification to examine land cover changes and the Ministry of Forestry Regulation No. P61 of 2014 for water management evaluation. The largest land use conversion occurred in paddy fields, which decreased by 3,731.37 hectares, shrubs decreased by 1,484.87 hectares, mixed dryland agriculture by 1,017.29 hectares, water bodies by 317.60 hectares, mangrove forests by 218.27 hectares, and swamp shrubs by 26.99 hectares. These areas were converted into settlements covering 4,348.42 hectares, dryland agriculture 2,070.95 hectares, plantation forests 155.63 hectares, secondary dryland forests 34.01 hectares, airports 93.80 hectares, fish ponds 68.16 hectares, open land 19.16 hectares, and savannas 6.25 hectares. From the water management aspect, Flow Regime Coefficient value was >110, classified as very high, Annual Flow Coefficient was >0.5, also very high; sediment load and flooding were categorized as very high, and Water Usage Index value was <1700, categorized as very poor. As a result, the water management of the Tallo Watershed is classified as very poor, with a score of >130. The water management carrying capacity of Tallo Watershed falls into very poor classification from 2003 to 2022, mainly due to land use conversion and forest area covering only 11% of the total Tallo Watershed area.

Abstract

The Bajo Mola Raya settlement on Wangi-wangi Island, Wakatobi Regency, is experiencing development that does not align with spatial planning aspects. This research aims to analyze the development of existing residential land use in the Mola Raya area in accordance with the Regional Spatial Plan (RTRW) of Wakatobi Regency; to identify the factors causing the development of residential land use in the Mola Raya area in accordance with the Regional Spatial Plan (RTRW) of Wakatobi Regency, which consists of external and internal factors. External factors include: (a) population growth; (b) community economy; and (c) community socio-culture, while internal factors consist of (d) supervision; (e) licensing; and (f) enforcement. The method used is the map overlay technique. This analysis begins with the results of on-screen digitization of Google Earth imagery from 2018. Then, an overlay technique was performed with the spatial planning map of the Wangi-Wangi Island residential area and a descriptive presentation of the results from the FFA analysis, interviews, and FGDs. The results of this study indicate that the development of residential areas not in accordance with the RTRWK is found in Mola Utara Village with a conformity of 76.53% and Mola Nelayan Bakti Village with 76.87% conformity to the spatial planning of the Wangi-Wangi Island residential area. Furthermore, the factors most influencing the development of the Bajo Mola Raya settlement were found to be the increase in population, the economy of the community, and the socio-cultural aspects of the society. The internal factors indicate a lack of supervision, licensing, and enforcement from the local government.

Abstract

Pertumbuhan kawasan permukiman di Kota Makassar menghadirkan tantangan dalam pengelolaan lanskap yang berkelanjutan, terutama dalam penerapan prinsip green concept sebagai bagian dari pembangunan berwawasan lingkungan. Penelitian ini bertujuan untuk mengevaluasi pengelolaan lanskap permukiman berbasis green concept dalam perspektif urban sustainability, serta menganalisis perbedaannya berdasarkan strata sosial masyarakat dan tipe pengelolaan kawasan. Pendekatan yang digunakan adalah kuantitatif dengan paradigma positivisme, melalui pembobotan dan skoring indikator-indikator manajemen lanskap, kegiatan fisik pemeliharaan, dan peremajaan tanaman. Pengumpulan data dilakukan melalui kuesioner dan observasi pada empat kawasan permukiman dengan total 120 responden. Hasil penelitian menunjukkan bahwa secara umum pengelolaan lanskap berada pada kategori cukup (skor 2,98), dengan skor tertinggi pada aspek manajemen (3,16) dan terendah pada aspek peremajaan (2,93). Pengembangan lanskap lebih optimal ditemukan pada kawasan yang dikelola oleh developer dan dihuni masyarakat strata sosial menengah ke atas. Sebaliknya, kawasan yang dikelola oleh pemerintah/masyarakat serta dihuni oleh masyarakat menengah ke bawah menunjukkan kualitas lanskap yang lebih rendah. Temuan ini menunjukkan pentingnya peran tata kelola, dukungan kelembagaan, dan keterlibatan masyarakat dalam mewujudkan lanskap permukiman yang berkelanjutan, serta memberikan rekomendasi untuk penguatan kebijakan pengelolaan lanskap berbasis green concept di tingkat lokal.

Abstract

This study investigated the lateral distribution of geochemical parameters in peatlands within the Punggur Besar River–Kapuas River Peat Hydrology Unit (KHG) in Kubu Raya District, West Kalimantan Province, Indonesia. Peatland degradation in this area is primarily caused by land clearing, uncontrolled drainage, and forest fires, which adversely impact the soil's physical and chemical properties. Key geochemical parameters analyzed include nitrogen (N), phosphorus (P), potassium (K), pH, organic carbon, and cation exchange capacity (CEC). Spatial distribution was mapped using GIS technology. The results showed significant variation in nutrient content and soil pH across the study area. Nitrogen content varied between 0.1% and 1.6%, indicating areas of high and low vegetation productivity. Low phosphorus levels in most regions suggest nutrient deficiencies, while potassium concentrations exhibit variability, indicating a potential need for fertilization. Predominantly acidic soil pH (2.8-6.3) challenges vegetation growth and increases fire risk. These discoveries contribute to a fundamental understanding of the geochemical dynamics of peatlands, indispensable for leading sustainable management and restoration efforts. By recognizing areas of high fertility and those requiring restoration interventions, this research assists effective land-use planning and climate mitigation strategies in degraded peatland ecosystems.
