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."
