Abstract

This study analyzes the quality of  meranti tembaga wood from natural forests with a maximum diameter of 50 cm as a material for the timber management industry. Furthermore, the study also examined the quality of meranti tembaga wood (Shorea leprosula Miq.) from silin engineering plants with diameters of 28 cm, 36 cm, 43 cm, and 51 cm.  This study also examines the diversification of the use of copper meranti wood from silin engineering plants to explore the potential applications of this wood in various industries. Meranti tembaga wood samples were taken from natural forests and plantation forests (intensive silviculture/silin) of PBPH PT Dwimajaya Utama, Central Kalimantan. Furthermore, wood anatomy testing was carried out at the Forest Hasi Technology Laboratory, Gadjah Mada University. The quality of Copper meranti wood from natural forests with a minimum diameter of 50 cm for the wood processing industry was studied. The results of the analysis of the quality of  meranti tembaga wood from Silin engineering plants showed significant variations based on diameter. For a diameter of 28 cm, the cell wall thickness is 1.675 and the lumen diameter is 22.752. For a diameter of 36 cm, the cell wall thickness is 1,633 and the lumen diameter is 20,739. For a diameter of 43 cm, the cell wall thickness is 1.592 and the lumen diameter is 2.268. For a diameter of 51 cm, the cell wall thickness is 1,738 and the lumen diameter is 21,066.

Abstract

Katingan Regency is recorded as one of the regions with a significant production of Non-Timber Forest Products (NTFP), specifically rattan. In managing Community Forests, baseline data containing the potential resources within is required. This rattan potential data is used to formulate the Community Forest Management Plan. This study aims to estimate the potential of rattan in the Community Forest area of Tumbang Habangoi, Katingan Regency. Forest stand stratification was processed using the Forest Canopy Density (FCD) Model. The FCD is a vegetation index transformation developed by Rikimaru from the International Tropical Timber Organization – Japan Overseas Forestry Consultant Association (ITTO – JOFCA) and P.S. Roy from the Indian Institute of Remote Sensing in 1999, using Landsat TM imagery data as the primary input. The FCD results can distinguish canopy coverage with an accuracy of nearly 90%, enabling differentiation in canopy density. The FCD will be evenly distributed across 30 sample plots in the field. The number of sample plots, set at 30, is based on literature suggesting that a sufficient number of clustered image samples is around 25 evenly distributed sample plots. The rattan in the Community Forest of Tumbang Habangoi has an estimated total potential of approximately ±7,786.4 tons, averaging ±4.2 tons/ha. The growth of rattan heavily depends on the structure of the forest stands and the climbing trees supporting the rattan. The Forest Canopy Density Model is effective in mapping the horizontal structure of stands in Lowland Tropical Forests

Abstract

Studi ini dilakukan dengan penggabungan dua metode analisis yaitu teknik pengukuran di lapangan nondestructive dan Interpretasi foto udara menggunakan UAV, yang berfokus untuk mengetahui Jumlah Pohon, Biomassa dan Stok C pada tegakan S. balangeran di kawasan Hutan Kota Pulang Pisau. Hasil studi menunjukan Jumlah Pohon tegakan S. balangeran sebanyak 3.278 pohon dengan luas area penanaman 5,62 Ha, serta Biomassa dan Stok C secara berurut sebesar 1.444,30 ton dan 678,82 ton. Jika diakumulasi kedalam hektar maka tegakan S. balangeran memiliki potensi Biomassa 256,99 ton/ha dan Stok C 120,78 ton/ha. Hasil tersebut menunjukan bahwa kombinasi dua metode analisis dalam studi mampu mempermudah proses estimasi Biomassa dan Stok C tegakan.

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

This study analyzes the growing challenges of municipal solid waste management in Palangka Raya, driven by rapid population growth and limited landfill capacity. The research aims to develop an integrated dynamic system model combining population dynamics and waste management performance to project future conditions and evaluate policy interventions. Using a system dynamics approach, the study models population growth, household waste generation, landfill accumulation, and waste reduction strategies. Primary data were collected through field measurements of existing waste volumes and landfill capacities, while secondary data were obtained from official statistics and relevant reports. Model validation demonstrates high accuracy in projecting population growth, a key driver of increasing waste generation. Simulation results indicate that, under the current conditions, the Bukit Tunggal landfill will reach overload in 2018, revealing an unsustainable system. Moderate interventions produce minimal improvement, while an optimistic scenario delays landfill overload only until 2026. The findings demonstrate that achieving long-term landfill sustainability requires an extreme waste reduction strategy of at least 85% through significant enhancement of recycling, composting, and waste diversion efforts. The study concludes that incremental policies are inadequate to address the worsening waste crisis. Instead, a transformative shift toward high-performance waste processing and decisive policy intervention is essential to maintain landfill functionality and support sustainable urban development. The integrated model developed in this research provides a valuable tool for policymakers to design effective and long-term waste management strategies.

Abstract

The frequent forest fires along the Sebangau River in Central Kalimantan, particularly during the dry season, have emerged as a significant environmental issue, driven by human activities such as the burning of wild pandanus on the riverbanks to facilitate the deployment of fishing equipment. This study examines the correlation between community behavior, particularly among fishermen, and the occurrence of forest fires in the Sebangau watershed, while also investigating the causes of these fires. The research methodology employs a combined approach, using remote sensing analysis (MODIS) to map forest fire patterns spatially, alongside observations from local groups to gather qualitative data on land-burning practices. The study's findings indicated that forest fires along the Sebangau River were predominantly caused by fishermen burning wild pandanus, often leading to uncontrolled spread. The El Niño phenomenon exacerbates drought conditions that instigate fires. This study underscores the significance of a community-oriented strategy for forest fire mitigation and the necessity of sustainable management practices that foster collaboration between governmental entities and communities to reduce the likelihood of future forest fires.
