Dinamika Indeks Kekeringan Terhadap Perubahan Iklim Di Sub-DAS Upper Brantas, Jawa Timur

Mahmud Zakariyah — 2025-01-30

Drought is one of the significant impacts of climate change that affects water availability, agricultural productivity and ecosystem sustainability. This research aims to analyze the drought index in the Upper Brantas River Sub-Watershed (DAS) area, which plays an important role in the agricultural sector of the local community. The drought index is calculated based on the ratio of annual precipitation to annual potential evapotranspiration, with precipitation and evapotranspiration data obtained from the Global Agro Ecological Zone (GAEZ) V4 Data Portal. This research utilizes the Representative Concentration Pathways (RCP) 4.5 and RCP 8.5 climate change scenarios in four time periods: 1981–2010, 2011–2040, 2041–2070, and 2071–2100. The results show that precipitation tends to decrease under RCP 4.5, while RCP 8.5 shows fluctuations, but remains higher than the RCP 4.5 value. In contrast, potential evapotranspiration shows a significant increase, especially in the RCP 8.5 scenario. The combination of these changes produces a drought index pattern that tends to decrease, so that the Upper Brantas Subwatershed area becomes drier, with worse impacts in the RCP 8.5 scenario. Spatial analysis revealed a strong negative correlation between potential evapotranspiration and drought indices, confirming the role of evapotranspiration in exacerbating drought conditions. This research can be the basis for recommendations by emphasizing the urgency of adaptation to climate change, such as managing water resources, increasing farmer capacity, and optimizing sustainable agricultural practices, in order to minimize the impact of drought on the sustainability of the Upper Brantas Subwatershed area.

Tingkat Perkembangan Wilayah Kabupaten Dan Kota Di Pulau Jawa

Abila Krisna Wardana — 2025-01-30

Java Island has experienced rapid development in Indonesia, with a dense population and a crucial role in the trade, industry, services, culture sectors, as well as being the nation's food basket. Its economic growth has been driven by high urbanization in recent decades, creating new growth centers and increasing the demand for infrastructure. However, urbanization also presents challenges such as the emergence of megaregions, urban bias, and regional disparities. This study aims to determine the development level of regencies/cities in Java Island and the spatial patterns of their development. The method used is quantitative descriptive analysis with scaling techniques, Moran's I, and LISA. The dimensions used include economy, social, infrastructure and services, environmental, and ICT, consisting of 15 variables. The results show that in 2022, 31 regencies/cities on Java Island were classified as having a high level of development, 36 at a moderate level, and 52 at a low level. The regional development index on Java Island shows variations, where the economic and social dimensions are dominated by large cities such as Jakarta and Surabaya, while regions with lower indexes are spread across East Java. The infrastructure and services, as well as the ICT dimensions, show significant disparities, with areas like the Thousand Islands excelling in infrastructure access, while Lebak Regency and Cimahi City face limitations. Most regencies/cities are still at a low level of regional development, requiring interventions to improve infrastructure, the economy, and the quality of life to achieve more equitable development. The emerging spatial patterns show clustering or positive autocorrelation around metropolitan areas. There is a need for equity strategies to reduce disparities between regions, especially those far from metropolitan or megaregion areas.

Geospatial Analysis Of Noise Pollution From Power Plant Operations In Urban Residential Areas: A Study of PLTD Telaga, Gorontalo Province

Irawan Matalapu — 2025-01-30

Seiring dengan pertumbuhan populasi dan urbanisasi yang pesat, kebisingan telah menjadi masalah serius yang terus dalam lingkungan pemukiman perkotaan. Berbagai aktivitas manusia seperti transportasi, konstruksi, industri, serta kegiatan komersial berkontribusi signifikan terhadap kebisingan. Penelitian ini bertujuan untuk menganalisis tingkat kebisingan yang dihasilkan oleh Pembangkit Listrik Tenaga Diesel (PLTD) Telaga, Provinsi Gorontalo, serta distribusinya pada area pemukiman di sekitarnya menggunakan pendekatan geospasial. Kebisingan dari operasional PLTD Telaga berpotensi memberikan dampak negatif pada kualitas hidup masyarakat, terutama terkait gangguan kesehatan fisik dan mental. Penelitian ini menggabungkan metode pengukuran kebisingan dengan analisis spasial berbasis Sistem Informasi Geografis (SIG) untuk memetakan distribusi kebisingan. Pengukuran dilakukan pada berbagai titik di sekitar PLTD dan pemukiman dengan menggunakan Sound Level Meter. Data yang dikumpulkan dianalisis untuk mengetahui tingkat kebisingan pada waktu beban normal dan beban puncak. Hasil penelitian menunjukkan bahwa tingkat kebisingan di area kerja PLTD secara signifikan melebihi ambang batas yang diperbolehkan, yaitu mencapai 109-110 dBA, sementara kebisingan di area pemukiman bervariasi antara 50-77 dBA. Hasil analisis spasial menunjukkan bahwa distribusi kebisingan tertinggi berada di area sekitar mesin PLTD dan sebagian kecil area pemukiman terdekat. Temuan ini menunjukkan perlunya tindakan mitigasi seperti pengaturan jam kerja, penggunaan alat pelindung diri (APD), dan perbaikan tata ruang untuk mengurangi dampak kebisingan terhadap masyarakat sekitar. Penelitian ini diharapkan dapat menjadi acuan dalam perencanaan tata ruang kota dan pengelolaan lingkungan yang lebih baik di sekitar area PLTD Telaga.

Nirmawana Simarmata — 2025-01-30

Forest and land fires are common natural disasters in Indonesia, impacting ecology, economy, and community welfare. This study aims to calculate the spatial risk of Karhutla in Pesawaran Regency as an initial step in disaster management. The data comes from Landsat 8 (OLI) satellite images, slope maps, road maps, rivers, and land cover of Pesawaran Regency. This disaster risk assessment method refers to Decree from the BNPB Head Number 2 on year 2012 with three risk components in the form of vulnerability, hazard, and capacity indices. The hazard index was analyzed using hazard assessment variables, spatial analysis, and attribute analysis. The index of vulnerability is conducted by analyzing the conditions and characteristics of the community and its environment to calculate which factors reduce the ability to cope with disasters. The capacity index is calculated based on five leading indicators: disaster management rules and institutions, early warning systems and disaster risk assessments, disaster education, essential risk factor reduction, and preparedness development at all levels. The calculated hazard, vulnerability, and capacity indices were then combined to assess the risk level of land and forest fire disasters. An analysis from forest and land fire disaster risk assessment results in Pesawaran Regency shows that majority of the area have a medium risk. The largest sub-district with a low-risk level is in Pandan Island Sub-district with an area of 11,332.6 hectare, and the largest sub-district with a high level is in Tegineneng Sub-district of 11,558.3 hectare area, followed by Gedong Meneng sub-district. These sub-districts could be prioritized for a holistic and integrated scheme to add capacity index by all stakeholders.

Mount Muria, located in Kudus Regency, has immense natural potential as a destination for special-interest tourism, particularly hiking. However, its development and utilization remain suboptimal. One major challenge is the lack of structured and accessible information about hiking trails, making it difficult for visitors to plan their hikes. This study aims to analyze the characteristics of hiking trails on Mount Muria. The research focuses on the trails in Rahtawu Village, specifically Natas Angin Peak and Peak 29. Data were collected through field surveys involving direct observation, documentation (travel distance, time, slope, and facilities), and trekking (coordinates of checkpoints and facilities). The analysis employs a percentage descriptive method to evaluate hiking trail scores based on distance, slope, time, and facilities. Results show that the Natas Angin trail is 3,720 meters long with an average slope of 30.33%, leading to a longer travel time of approximately 204 minutes. In contrast, the Peak 29 trail is 5,004 meters long with a gentler slope of 15%, allowing for a shorter travel time of about 192 minutes. While shorter, the Natas Angin trail is more challenging, making it better suited for experienced hikers, whereas Peak 29 is more suitable for beginners. This study provides valuable information for hikers to plan their trips and emphasizes the importance of optimizing trail information to improve safety and comfort during hikes on Mount Muria.
