Abstract

Indonesia is characterized by a diverse topography and low to very high rainfall intensity.  In addition, the population density in fertile Indonesian hilly areas is also increasing.  These conditions translate to high potential for landslide hazard in Indonesia with threats of loss ranging from economic, social, to fatalities.  One of the areas with a high level of landslide hazard is Padalarang Subdistrict, West Bandung Regency, West Java Province.  The purpose of this research is to identify the landslide hazard in Padalarang Subdistrict, West Bandung Regency.  Geographic Information System Analysis was used in this study by using an overlay technique presented on the map.  The analytical method used was a survey-exploratory analysis with descriptive analysis techniques.  The results showed that the landslide hazard in Padalarang Subdistrict could be divided into three categories; having landslide hazard in the north, having landslide potential in the north to the west and southeast, and having no landslide hazard in the central to southern parts which are alluvial plains.  Analysis of the landslide hazard in Padalarang Subdistrict provided a spatial picture so that it could be potentially employed to be part of disaster mitigation to minimize material and non-material losses.

Abstract

The development in the city has caused urban areas to experience significant growth due to increased activity. One of the visible changes is the change in the use of vegetated land for built-up land. The research location is in a peri-urban area of Depok and Mlati subdistrict, Sleman Regency. This research analyzed land use conversion in 2015-2020 and modeled land change predictions for the next 20 years (2025-2045) using Artificial Neural Network - Cellular Automata (ANN-CA). The ANN method used multiple output neurons to determine the probability of land use transition. CA was used to model land use change by applying transition probabilities. The source of land use data came from extracting SPOT images, and then the modeling process used QGIS Desktop 2.18.11 on the MOLUSCE plugin. The results showed that the peri-urban area experienced a decrease in agricultural and livestock land by 152.62 ha (2.52%) while building land increased by 148.74 ha (2.46%). The 2025-2045 land use conversion prediction shows that the reduction in agricultural land, plantations, and livestock will continue, and the land area for buildings and roads will increase.

Abstract

The Central Sleman area is a peri-urban area directly adjacent to Yogyakarta, making land conversion increasingly prevalent and unavoidable. In comparison, the Central Sleman area has a role as one of the food barns due to fertile land conditions and is suitable for agriculture. Intensive conversion of agricultural land to non-agricultural land will result in the loss of productive agricultural land, resulting in decreased rice production. This will result in high rice imports and reduced employment in the agricultural sector. This research aims to analyze the development of agricultural land use, its projection, and the carrying capacity of agricultural land in the Central Sleman Region. The calculation of the agricultural land carrying capacity is based on Odum, Howard, and Issard. The results showed that the Central Sleman Area has a decreasing rate of change in the agricultural land area every year in Kapanewon. The calculation results of agricultural land's carrying capacity show that in 2020, land's carrying capacity exceeded 0.83. The results of the projection calculation in 2024 found that 4 out of 5 Kapanewon in the Central Sleman Region cannot achieve food self-sufficiency. Therefore, efforts are needed to increase the carrying capacity of agricultural land, mainly through increasing the productivity of food crops and protecting agricultural land from land conversion.

Abstract

Kulon Progo Government plans to make Pasir mendit and Pasir kadilangu areas agro-tourism of shrimp ponds. The success of a regional development program is usually associated with technical problems and socialization. However, the readiness and ability of the community and the positive perception of the community affect the success of regional development programs. This study aims to assess the socio-economic conditions, determine the public perception of agro-tourism shrimp pond development, and determine the factors that affect public perception of agro-tourism shrimp pond development. Primary data were obtained using a survey method with observation and interview techniques. Descriptive-qualitative analyzed the data through frequency tables, cross tables, and images, while quantitative analysis was carried out based on the regression and multiple linear regression results. The results showed that social and economic conditions are pretty good and rising after the development of shrimp pond farming in Pasir mendit and Pasir kadilangu. In this regard, the public perception of agro-tourism development of shrimp farming areas can be pretty high and agreed on the construction of several considerations. The factors that significantly affect the public perception of agro-tourism products are general knowledge about agro-tourism and income levels.

Abstract

Kekeringan yang terjadi secara periodik di wilayah Soe menimbulkan tekanan besar terhadap kebutuhan dan ketersediaan air baku, sehingga diperlukan strategi pengelolaan airtanah yang berkelanjutan. Penelitian ini bertujuan untuk mengidentifikasi potensi dan arah aliran airtanah melalui integrasi metode resistivitas dan pemetaan hidrogeologi. Pengukuran dilakukan menggunakan konfigurasi Schlumberger pada 14 titik sounding dengan bentangan maksimum 500 meter. Hasil pengolahan menunjukkan tiga sistem akuifer, yaitu menggantung, bebas, dan tertekan. Akuifer produktif utama terdapat pada batuan karbonat dengan nilai resistivitas 30–150 Ohmmeter, sedangkan lapisan penutup berupa napal memiliki resistivitas rendah (<10 Ohmmeter). Berdasarkan peta muka airtanah dan analisis anisotropi, aliran airtanah bergerak dari bagian utara menuju selatan daerah penelitian serta sebagian mengarah ke tenggara dan barat daya mengikuti gradien topografi. Integrasi hasil geolistrik dan hidrogeologi ini efektif untuk menentukan zona konservasi dan pemanfaatan airtanah berkelanjutan sebagai langkah mitigasi kekeringan.
