Abstract

Johar (Senna siamea) is a plant commonly planted in reclaimed land. It was chosen because of its ability to adapt to infertile soil conditions such as reclaimed land. Next, an experiment was conducted to plant johar plants with a planting medium of soil, compost and cocopeat plus certain fungi and microbes that are useful for accelerating growth. A total of 60 johar plants were planted in these media in polybags (30 cm x 18 cm) with the treatment of Johar A (soil: compost = 70: 30 + fungi + bacteria), johar B (soil: compost = 40: 60 + fungi + bacteria), Johar C (soil: compost: cocopeat = 1: 1: 1 + fungi) and johar D (soil: compost = 1: 1) as a control. Plants were maintained for 12 weeks and observed every week for the growth of stem height and stem diameter. The test was carried out 15 replications. The results obtained in all observations with statistical tests were not significantly different (p <0.05). The conclusion of this experiment is that this factory-made compost can be used as a growing medium for johar, so that all compost media formulas are still suitable as growing media for growing young johar plants.

Abstract

Research has demonstrated the treatments using sawdust–cement ratios of A1 (1:1.5), A2 (1:2), A3 (1:2.5), and A4 (1:3) in the manufacture of red meranti wood particle cement boards based on the SNI 03-2105-2006 standard. The results showed that the physical and mechanical properties of red meranti sawdust cement boards met the standards for moisture content, density, and thickness swelling. However, the modulus of elasticity (MoE) and modulus of rupture (MoR) did not meet the SNI 03-2105-2006 requirements. The analysis of variance indicated that the sawdust–cement ratio treatments had no significant effect on moisture content, density, and thickness swelling, but had a significant effect on the modulus of elasticity (MoE) and modulus of rupture (MoR), with the best treatment being A1 (1:1.5). The quality of the red meranti sawdust cement board falls under the ordinary type 1 particle cement board with a thickness of 13 mm and medium density, and is therefore recommended for non-structural uses such as interior partition walls, ceilings, decorative purposes, and tabletops.

Abstract

The success of revegetation in post-coal mining areas is generally evaluated through manual field surveys, which are time-consuming, costly, and often subjective. This study offers an alternative quantitative approach using the Red-Green-Blue Vegetation Index (RGBVI) calculated from high-resolution drone imagery to monitor canopy cover in coal mine reclamation areas. The research was conducted on a 1-hectare reclamation site located in Tabalong District, South Kalimantan, Indonesia. UAV flights were carried out using a DJI Phantom 4 Pro at an altitude of 100 meters and analyzed with QGIS 3.34. Vegetation cover was classified using the RGBVI formula with a threshold value of 0.30 and validated through field measurements of canopy diameter. The results showed that canopy cover derived from image analysis reached 69%, while the ground check data indicated 75%, yielding an accuracy level of 92%. The RGBVI effectively distinguished between vegetated and non-vegetated areas and demonstrated a strong correlation with field data. These findings confirm that RGB drone imagery is a reliable, efficient, and low-cost ecological monitoring tool that supports the development of digital reclamation evaluation systems in tropical mining regions.

Abstract

Pulang Pisau Regency in Central Kalimantan is known for its extensive peatland ecosystems, which are rich in biodiversity. Peat ecosystems function not only as major carbon sinks but also as habitats for various local non-timber forest product (NTFP) species that have long supported the socio-economic livelihoods of local communities. This study was conducted to identify local NTFP species that grow within the peatland ecosystems of Pulang Pisau and to assess their ecological and economic utilization potential. Through field surveys, vegetation inventories, and interviews with Indigenous communities and local artisans, the research identified several key species such as swamp jelutung (Dyera polyphylla), purun (Eleocharis dulcis), rattan (Calamus spp.), tengang (Shorea balangeran), various medicinal plants, forest honey, and peat swamp food plants. Each species offers diverse utilization prospects, ranging from handicraft industries and traditional medicine to local food resources and peatland restoration efforts. These findings indicate that NTFPs hold strategic potential as a foundation for a green economy and as a contributor to the sustainability of peatland ecosystems in Pulang Pisau Regency.

Abstract

This study investigates the spatio-temporal changes in land surface temperature (LST) patterns in Jambi  City, Indonesia, between 2013 and 2024 using Landsat 8-9 OLI/TIRS imagery. The research employs thermal band analysis (bands 10 and 11) and geographical information systems to evaluate urban heat  island (UHI) effects across 68 sub-districts. Results demonstrate significant thermal    landscapetransformations, with surface temperatures expanding from 21.5-26.20°C in 2013 to 19.02-27.33°C  in 2024. Highly urbanized areas, particularly in Jambi Selatan, Jelutung, and Paal Merah districts, experienced the most substantial temperature increases (up to 1.13°C), while areas maintaining vegetation cover and proximity to water bodies showed remarkable thermal stability. The study reveals strong correlations between land use changes and temperature variations, with built-up areas exhibiting significantly higher temperatures compared to vegetated regions and water bodies. These findings provide crucial insights for urban planning and climate adaptation strategies, emphasizing the importance of preserving green spaces and water bodies as natural cooling mechanisms in rapidly developing tropical cities.

Abstract

Coastal plant genetic resources (CPGR) are strategic assets for food security, local livelihoods, and climate resilience in Indonesia’s lowland and estuarine landscapes. However, coastal ecosystems in Central Kalimantan are increasingly threatened by land conversion, abrasion, and the rapid diffusion of uniform high-yield varieties. This study analyses the composition, spatial distribution, and management of CPGR in three coastal sub-districts—Teluk Sampit (Kotawaringin Timur), Seruyan Hilir (Seruyan), and Kumai (Kotawaringin Barat)—and formulates strategic directions for their sustainable management. A descriptive–analytical mixed-methods design was applied, combining field observations, soil sampling, semi-structured interviews with farmers, local customary leaders, government agencies, and NGOs, as well as analysis of secondary data and spatial information. Soils across the three sites are dominated by sandy clay loam and loam with strongly to moderately acidic pH (4.4–5.4), high cation exchange capacity, very high exchangeable K, but low Ca–Mg, indicating leached acid coastal soils that favour tolerant crops yet require careful management for intensive agriculture. Coastal plant genetic resources are dominated by mangroves (Rhizophora, Bruguiera, Avicennia), nipah (Nypa fruticans), local coconuts, tidal rice landraces (e.g. Siam Epang and Sekonyer), and emerging horticultural crops such as watermelon and avocado. Each sub-district shows distinct configurations: Teluk Sampit as a mangrove–tidal rice–coconut landscape with a registered geographical indication of Siam Epang; Seruyan Hilir as a nipah–rice–pond mosaic with growing nipah sugar enterprises; and Kumai as a conservation–production mosaic linked to Tanjung Puting National Park and coastal ecotourism. These CPGR underpin household income, employment, and local food systems but face pressures from oil-palm expansion, ageing coconut stands, aquaculture, and infrastructure constraints. Institutional arrangements remain fragmented, with multiple actors but weak formal coordination. Strengthening CPGR management in Central Kalimantan requires integrating in situ conservation with productivity improvement and value addition, recognition and protection of local varieties, and the establishment of an inclusive multi-stakeholder forum and regional action plan to support collaborative governance and long-term coastal resilience.

Abstract

In today's digital era, training and professional competency development in using mobile applications is crucial. To help the public understand their Community Preparedness Index (CSI), the government has created an application called InaRISK Personal. This online application, available for Android and iOS, provides information on the hazard level of an area and provides action recommendations for participatory anticipation. This application was developed jointly by the government and other parties experienced in disaster education in Indonesia. In its development, InaRISK Personal includes several additional features to support disaster risk reduction efforts, including vulnerability surveys and household-level preparedness. The results of this training are also expected to serve as a basis for village officials and the community regarding disaster management at the regional and village levels. Therefore, we took a role in initiating the activity "Training on Using the InaRisk Personal Application to Determine Community Preparedness in Disaster Mitigation in Katingan Regency."

Abstract

The large contribution of the kelulut honey business to the income of households or farmer families can help family income. Bahu Palawa Village has formed a Social Forestry Business Group (KUPS) that cultivates kelulut honey, but until now it is not clear how the contribution of the kelulut honey business to the income of farmer groups in Bahu Palawa Village. This study was conducted to see how much contribution kelulut honey cultivation makes to the household income of farmers in Bahu Palawa Village. This study aims to analyze the contribution of income from the kelulut honey business and analyze the problems faced by the Kelulut honey KUPS in Bahu Palawa Village. The method used is a census of KUPS members as many as 17 respondents where their income and income will be analyzed. The results obtained from the research conducted are the income of members in KUPS with an average of Rp. Rp.1.088.259/family/year with a total of 17 members. The income of members outside the KUPS is honey kelulut with an average of Rp.6.294.118/family/year. The contribution of income in KUPS from 17 members of the contribution group of 1.74% is included in the very insufficient category. The problems faced include uncertain weather factors such as high rainfall that reduces bee activities, obstacles in marketing due to lack of market reach and effective promotional strategies, and business management that is still simple with limitations in production planning, human resources, raw materials, and business capital.

Abstract

Peatlands are important ecosystems that play a crucial role in maintaining environmental balance, particularly in tropical regions such as Palangka Raya, Central of Kalimantan. This study aims to identify the physical and chemical characteristics of peat soils surrounding the Laboratorium Terpadu area at Palangka raya University, to support sustainable land management and campus environmental conservation. The results indicate that the peat soils at the site have a high water content (111.1%) and low bulk density (0.22 g/cm³), reflecting saturated, porous soil with a potential risk of subsidence if hydrological conditions are altered. Soil chemical properties show a pH of 4.3, indicating high acidity with low nutrient availability, and reflecting a relatively natural ecosystem. These physical and chemical characteristics have important implications for land use planning, vegetation cultivation, and campus spatial development, emphasizing the need for amelioration strategies, proper fertilization, and construction techniques that account for soil subsidence risks. This study provides a scientific basis for the wise and sustainable management of peatlands within the campus environment.
