Doktrin Hutan Negara Dalam Uu No. 5 Tahun 1967: Awal Sentralisasi Kekuasaan Dan Birokratisasi Hutan Di Indonesia
type: item
description: The transition from colonial rule to independence in Indonesia did not immediately end the paradigm of state control over natural resources. This research examines how the Basic Forestry Law (Law No. 5 of 1967) became a fundamental legal instrument that legitimised the state's authoritarian control over forests. Using qualitative content analysis of Law No. 5 of 1967 and its explanation, this study aims to reveal the legal mechanisms used by the New Order regime to institutionalise the state forest doctrine, as well as to design a highly centralised and bureaucratic management structure. The findings indicate that this law effectively consolidates state power in the hands of the central forestry bureaucracy, marginalises the rights of indigenous communities, and provides legal justification for large-scale forest exploitation. Thus, this article argues that Law No. 5 of 1967 was not merely a product of technical regulation, but a political document that laid the foundation for a state-centric model of forest governance, the impact of which is still strongly felt in contemporary forestry issues. This study confirms the need to understand the historical roots of existing forestry policies in order to formulate future reforms.

Pengaruh Formulasi Serbuk Kayu dan Perekat terhadap Karakteristik Dasar Briket Arang Kayu Ulin
type: item
description: Charcoal briquettes are a type of biomass-based alternative fuel regarded as having greater ecological compatibility and economically advantageous compared to fossil fuels. The present study is intended to transform ironwood (Eusideroxylon zwageri) sawdust waste into charcoal briquettes, utilizing tapioca starch binder in varying proportions. The research methods include the carbonization of ironwood sawdust, charcoal pulverization, mixing with tapioca binder, moulding, drying, and evaluation of the briquettes’ physical and chemical attributes. The findings reveal that the proportion of sawdust to binder has no influence on the density, moisture content, or volatile matter of the briquettes; however, it markedly affects the ash content. The calorific values of all the samples comply with the quality requirements specified in SNI 01-6235-2000, although the volatile matter content exceeds the permissible limit. The briquette with formulation C (formulation of sawdust, tapioca, and water namely 2000 g, 300 g, and 300 ml) demonstrated the most optimal performance, with the highest calorific value. This study confirms that ironwood sawdust waste can be effectively utilized in the manufacture of superior charcoal briquettes, representing a sustainable and economically attractive substitute for conventional energy source.

Keanekaragaman Jenis Burung Di Zona Pemanfaatan Dan Zona Tradisional Resort Musuk Cepogo Taman Nasional Gunung Merapi
type: item
description: A high diversity of bird species in an area indicates that the region has a healthy environmental condition. The natural habitat conditions support various bird species living in the Mount Merapi National Park (TNGM) area. The purpose of this research is to determine the species diversity index, feeding guild types, and conservation status of birds in the utilization zone and traditional zone. This research was conducted in May 2025 at the Musuk Cepogo Resort, Mount Merapi National Park (TNGM). The method used was fixed-radius point count along transects. The distance between counting points was 150 meters with an observation radius of 50 meters. Observations were carried out in the morning and evening, with each counting point observed for 10 minutes. There were 15 counting points in the utilization zone (total effort: 150 minutes) and 20 in the traditional zone (total effort: 200 minutes). To account for unequal sampling effort, rarefaction analysis was performed. The results showed that in the utilization zone, 28 species with 167 individuals from 20 families were found, with a moderate species diversity value (H' = 2.98), high evenness (E = 0.90), no dominant species (D = 0.07), and high species richness (R = 5.28).

Sifat Fisika dan Kimia Tanah pada Tegakan Eucalyptus pellita di Hutan Tanaman Industri PT. Arara Abadi, Distrik Sorek, Provinsi Riau
type: item
description: Eucalyptus pellita is one of the main species in Industrial Plantation Forests (HTI) due to its rapid growth, short harvesting rotation, high productivity, and resistance to pests and diseases. However, land clearing and repeated harvesting activities may degrade soil physical and chemical properties. This study aimed to analyze the characteristics and differences in soil physical and chemical properties under Eucalyptus pellita stands aged 0–4 years in the Industrial Plantation Forest of PT Arara Abadi, Sorek District, Riau Province. A quantitative descriptive approach was applied with purposive sampling, followed by laboratory analysis. The results revealed that the soil physical properties were dominated by sandy clay loam texture with high bulk density (>1.65 g/cm³). This condition limits nutrient-holding capacity and potentially restricts root growth. Based on the chemical analysis, the soil was classified as very acidic (pH 3.92–4.34), with very low until low Cation Exchange Capacity (2.028–6.931 meq/100g), very low C-Organic (0.25–0.62%), very low until low Nitrogen (0.07–0.12%), very low Phosphorus (0.01–0.02%), and very low Potassium (<0.001–0.02%). These findings indicate a decline in soil quality, both physically and chemically, with increasing stand age.

Analisis Peran Kelompok Tani Hutan Konservasi dalam Rehabilitasi Ekosistem di Zona Rehabilitasi Resort Lawe Mamas, Taman Nasional Gunung Leuser
type: item
description: This study aims to analyse the level of effectiveness and contribution of the Conservation Forest Farmers Group (KTHK) as a management partner in supporting ecosystem rehabilitation in the Lawe Mamas Resort Rehabilitation Zone, Gunung Leuser National Park (TNGL). The study used a mixed methods approach with a qualitative approach reinforced by descriptive quantitative analysis through tabulation of KTHK role scores. Data were collected through in-depth interviews, field observations, and questionnaires from 41 informants consisting of government representatives, NGOs, community leaders, and KTHK chairpersons and members. The results of the study show that the educational role has the highest score (2.9), indicating a high level of effectiveness in providing information and raising awareness of conservation, while the economic and social roles are the lowest (2.1) due to limited market access and production facilities. In general, the institutional, participatory, and supervisory roles show fairly strong results with scores between 2.4 and 2.8. These findings confirm that the existence of KTHK contributes significantly to the sustainability of forest area rehabilitation, but requires institutional strengthening and economic support for more sustainable community participation.

Karbonisasi Limbah Biomassa Ampas Sagu Sebagai Bahan Baku Bioenergi
type: item
description: One source of biomass raw material is the sago plant (Metroroxylon sp). Sago (Metroroxylon sp) is vegetation that can produce starch to be used as a food source. Unt il now, sago tree processing waste, especially sago dregs, has not been utilized optimally and only a small portion is used as feed, especially for ruminants. Apart from that, sago dregs are dumped in shelters or along river flows at sago processing locations which results in environmental pollution. Because sago bark waste is biomass waste, it can potentially be used as raw material for bioenergy such as biopellets, biobriquettes, charcoal. The aim of the research is to look at the physical and chemical characteristics of raw materials. The method used refers to the Indonesian National Standard 01-6235 of 2000. The results obtained from this research are the physical properties, namely water content 11.3%, ash content 4.3%, volatile matter content 2.4% and calorific value 6,430 cal. /gram. Meanwhile, the chemical properties analyzed by GCMS contained 18.93% hydrocarbon compounds. Phenol compounds 57.4 %, Benzene compounds 11.41 %

title: Analisis Nonparametrik Laju Deforestasi dengan Model Spline Truncated Berbasis Faktor Sosial Ekonomi di Indonesiaic Analysis of Deforestation Rate with Truncated Spline Model Based on Socio-Economic Factors in Indonesia)
description: Indonesia is known as the "lungs of the world" due to its vast tropical rainforests, which play a crucial role in absorbing carbon dioxide and maintaining global climate stability. However, the sustainability of Indonesia's forests is increasingly threatened by population growth, agricultural land expansion, and the influx of foreign direct investment—defined as capital inflow from abroad into Indonesia in the form of physical assets or corporate ownership—which can lead to land-use changes and potentially accelerate deforestation if not managed sustainably. These factors have caused fluctuations in the deforestation rate over the past twelve years. This study aims to model the deforestation rate by considering relevant social, economic, and environmental variables. The method used is nonparametric truncated spline regression with a single knot point, which satisfies the assumptions of identically distributed, independent, and normally distributed residuals. The model explains 64.20% of the variation in deforestation rates, while the remaining variation is influenced by other factors outside the model. Forest cover area has been proven to have a significant effect on deforestation. These findings highlight the importance of adaptive and evidence-based policies to reduce deforestation, particularly through forest protection and controlling land conversion, in order to preserve Indonesia's ecosystem sustainability and biodiversity.
