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.
Dry Landslide in Sarwodadi Village, Pejawaran Sub-Regency; An Untypical Landslide in Banjarnegara Regency, Central Java Province, Indonesia Ahmad Rif&#039;an Khoirul Lisan; Muhammad Gazali Rachman; Tiara Sarastika; Oki Kurniawan

Abstract

Banjarnegara is known as a regency highly susceptible to landslides, with over half of its territory classified as having a high to very high level of landslide hazard. Mass movements in Banjarnegara, particularly within the Merawu Sub-watershed, are predominantly categorized as slides. Rainfall stands out as the primary triggering factor for landslides in this region. This study aims to dissect the causes and mechanisms behind a unique landslide event that occurred in Sarwodadi Village, Pejawaran Sub-regency, Pejawaran Regency, Central Java Province, on July 6, 2022, around 10:30 PM. Unlike typical occurrences, this landslide was not propelled by precipitation, which is commonly the principal catalyst for landslides in Banjarnegara. Employing a three-stage methodology involving secondary data collection, field observation, and data analysis, we have identified two potential explanations for the landslide event: the loss of support from the stress barrier and mass sliding. Given that the area remains an active mining site with inherent dynamics, proactive measures are imperative to mitigate the risk of future landslides. This is essential for safeguarding the safety of local mining activities, which constitute the primary source of income for many households in Sarwodadi and its environment. A comprehensive mapping and assessment initiative targeting areas with geological characteristics akin to those in Sarwodadi should be undertaken across Banjarnegara. Such endeavors would not only diminish the occurrence of landslides but also enhance public awareness concerning atypical landslide occurrences.

Abstract

The phenomenon of environmental degradation threatens various sectors, including agriculture in coastal ecosystems, thereby weakening the land’s carrying capacity. On the other hand, information about soil resources in fluvial-marine landscapes has formed a complex, unique system that influences geomorpho-pedological characteristics. This study aims to (1) investigate variations in soil morphological characteristics under different agricultural practices and (2) interpret the results of soil genesis processes within the framework of geomorpho-pedological evolution in fluvio-marine landscapes. The research was conducted in Tobo Ino Village, Wasile Subdistrict, Subaim, East Halmahera Regency, North Maluku Province, Indonesia. The methodology used was a stratified sampling method to identify soil profiles based on USDA standards for two different land-use practices. This was followed by laboratory-scale physicochemical analysis of the soil in accordance with the Agricultural Instrument Standardization Agency, Ministry of Agriculture, Indonesia. The results show that land use activities affect soil morphology and classification. Fluvaquentic Endoaquepts soil classification is found in rice paddy field practices, while Typic Eutrudepts is found in mixed plantations. Along with similar geomorphological conditions but different soil evolution processes, this results in different land resource management practices. This approach offers a process-based understanding that is essential for sustainable agricultural planning in dynamic coastal-alluvial landscapes in wet tropical regions to achieve the Sustainable Development Goals (SDGs) and the Eight Goals of the Unitary State of the Republic of Indonesia.
