Abstract

This research was conducted in Isimu Raya Village to assess the geotechnical conditions of the study area using quantitative field mapping methods and data analysis. The analysis encompassed the characterization of the physical and mechanical properties of soils, as well as rock analysis. The mapping results indicate that the study area comprises packstone limestone, elastic silt soil units, and low-plasticity sandy clay. Based on laboratory testing of soil physical properties, the elastic silt exhibited a liquid limit of 47.86% and plasticity index values of 48.89% and 54.08%. In contrast, the low-plasticity sandy clay showed a liquid limit of 48.61%, a plastic limit of 15.48%, and a plasticity index of 33.13%.

Abstract

Pengetahuan tentang perilaku kelompok jenis tuna dan cakalang pada areal rumpon merupakan bagian yang tidak terpisahkan sebagai strategi penangkapan optimal untuk mendapatkan ukuran ikan layak tangkap. Pengumpulan data di mulai tahun 2020-2024 dengan mengacu pada Prosedur Protokol Sampling untuk Pancing Tuna Artisanal Indonesia yang dikembangkan oleh United States Agency for International Development – Indonesia Marine and Climate Support (USAID-IMACS) bekerjasama dengan enumerator dari Masyarakat dan Perikanan Indonesia (MDPI). Kriteria ukuran tuna layak tangkap dianalisis berdasarkan length at first maturity (Lm). Hasil penelitian mengungkapkan bahwa prosentase hasil tangkapan dan ukuran layak tangkap pada areal rumpon menggunakan pancing ulur didominasi oleh tuna madidihang (Thunnus albacares) 76,32% dengan ukuran yang layak tangkap sebesar 44,27%, tuna mata besar (Thunnus obesus) 10,05% dengan ukuran layak tangkap 55,60%, dan cakalang (Katsuwonus pelamis) 5,09%  dengan ukuran layak tangkap 48,40%.  Sedangkan hasil tangkapan pancing ulur tanpa menggunakan rumpon atau di luar area rumpon berbeda jauh prosentase proporsi ukuran layak tangkapnya, yaitu 87,7%  untuk tuna madidihang; 97,65 %  tuna mata besar; dan cakalang layak tangkap sebesar 90,00%. Untuk mengurangi prosentase tertangkapnya ikan ukuran tidak layak tangkap, selain dengan strategi tanpa menggunakan rumpon juga dapat menerapkan metode pengaturan kedalaman penurunan alat tangkap, pengaturan waktu penangkapan, dan pengaturan ukuran mata pancing. Informasi ini sangat dibutuhkan dalam pengelolaan spesies tuna dan cakalang secara berkelanjutan khusunya untuk penangkapan pada areal rumpon.

Abstract

This community service program aims to develop Tongke-Tongke Tourism Village in Sinjai Regency through potential mapping and the utilization of local natural resources. The main problems identified include limited accessibility and the suboptimal use of local resources such as palm sugar and coffee. The implementation method employed a participatory approach involving observation, focus group discussions (FGD), and hands-on training in processing coffee drinks with palm sugar. The results show an improvement in community understanding and skills in managing tourism potential, as well as emerging initiatives to develop local beverage businesses. This activity contributes to enhancing community capacity in sustainable village tourism management and strengthens the local economy through innovation based on locally sourced natural resources.

Abstract

This study was conducted in Kalasari Village, Salawati District, Sorong Regency, Southwest Papua, within the Contract of Work area of PT Megapura Prima Industri. The research integrated field geological observations, detailed lithological and outcrop descriptions, drill core logging and correlation, and laboratory proximate analysis to characterize coal occurrence and quality. Stratigraphic analysis indicates that the study area is composed of two principal lithological units: the Sele Claystone Unit, deposited in backswamp to swamp environments, and the Sele Sandstone Unit, representing floodplain facies. Borehole correlation reveals coal seam thicknesses ranging from 0.3 to 1.82 m, with a general westward thickening trend, reflecting microtopographic variation and peat stability during deposition. The roof and floor of the coal seams are dominantly claystone or clayey sandstone, indicating overbank flood sedimentation that facilitated peat preservation. Proximate analysis shows that the coal is low rank, characterized by calorific values of 3220–3619 kcal/kg (adb), low ash content (1.7–3.8%), very low sulfur content (0.2%), and high total moisture (32–37%). These characteristics are typical of freshwater swamp–backswamp facies within an upper delta plain depositional environment with limited clastic input. The relatively thin overburden further constrained coalification, resulting in low calorific values. Overall, the results demonstrate that coal distribution, seam thickness, and coal quality in the study area are strongly controlled by upper delta plain depositional dynamics, particularly swamp and backswamp facies that governed peat accumulation and preservation.

Abstract

This study examines the geomorphological characteristics of Tilangobula Village in East Suwawa District, Bone Bolango Regency, Gorontalo Province, Indonesia, located within the tectonically active Limboto Zone. Through integrated field observations and geospatial analysis—including topographic maps, slope gradients, and drainage patterns—the research identifies structural hills as the dominant geomorphological unit, covering 2.356 km² with elevations ranging from 200 to 600 meters above sea level. The area exhibits two distinct drainage patterns (parallel and trellis) and variable slope gradients (2–140%). Morphogenetic analysis reveals the landscape has been shaped by both endogenic processes (notably oblique faulting, specifically a Normal Left Slip Fault) and exogenic factors (erosion of diorite and quartz diorite intrusions). The lithology comprises intrusive igneous rocks (diorite and quartz diorite), with structural features such as shear joints and faults further influencing the terrain. The findings highlight the interplay between tectonic forces and surface processes in forming the region’s unique structural hills, characterized by V-shaped valleys and steep slopes. This study provides critical baseline data for understanding understudied tectonic landscapes in eastern Indonesia and supports applications in regional geological research and land-use planning. The results underscore the importance of integrating morphographic, morphometric, and morphogenetic analyses to decipher complex geomorphological evolution in tectonically active regions.

Abstract

One of the regions in Indonesia with potential laterite nickel deposits is North Morowali, where the MTosu Formation, composed of Cretaceous-aged ultramafic rocks, is found. This study aims to identify the distribution of laterite and nickel content using data from Hand Auger analysis. The methods used include field observations, Hand Auger sampling, and geochemical analysis through X-Ray Fluorescence (XRF). The research area features two main geomorphological units: structural steep hills and structural gentle hills. Its stratigraphy consists of lherzolite and serpentinite units. The dominant geological structure trends northeast-southwest, following a linear pattern. Laterite distribution in the area is controlled by topography. Nickel content is categorized into three zones: high, medium, and low. XRF analysis of Hand Auger samples indicates that high nickel concentrations are located in the southwest and extend northeast across the study area.
