Abstract

The conversion of forest land to agriculture has affected the ecosystem in the upstream area of Way Betung Watershed, including Tanjung Agung Village. This study aims to analyze the relationship between knowledge, community participation, and agroforestry land conservation. The study was conducted on 30 respondents using a structured questionnaire, the results of which were analyzed using the Spearman Rank correlation test. The results showed that the level of community knowledge was in the moderate category (mean score 2.3), while the level of participation was high (mean score 3.7). The level of agroforestry land conservation was recorded in the moderate to high category (mean score 3.3). Correlation analysis showed a significant relationship between knowledge and community participation (ρ = 0.414, p = 0.023) with sufficient closeness, but no significant relationship was found between knowledge and land conservation (ρ = 0.219, p = 0.245) or participation and land conservation (ρ = 0.291, p = 0.119). This study highlights that increasing community participation has great potential to support the success of agroforestry conservation, although the contribution of knowledge needs to be strengthened. The novelty of this research lies in the in-depth analysis of the level of relationship between social variables in supporting agroforestry-based conservation in the strategic upstream area of the Way Betung Watershed.

Abstract

Bamboo is one of the most abundant non-timber resources, flourishing globally across tropical and subtropical regions. Its increasing appeal lies in its environmental sustainability, robust mechanical properties, and high recyclability. Nonetheless, bamboo's inherent hydrophilicity presents significant challenges, particularly in achieving optimal compatibility for applications such as construction materials. Economic and environmentally friendly heat treatment techniques have emerged as pivotal strategies for improving bamboo's surface properties. This article comprehensively reviews the effects of varying thermal treatment conditions, including temperature, duration, and medium, on bamboo's structural characteristics.

Abstract

The conversion of land in urban areas, especially Green Open Space (GOS), into development land causes green land to decrease, coupled with the increasing volume of vehicles. The rapid activity of manufacturing plants and excessive energy consumption are contributing factors to the increase in CO2 in the air, and the quantity and quality of O2 is declining. Green Open Space or city park is an open space that has ecological benefits, the space is filled by trees that form vegetation, socio-cultural benefits as a forum for interaction between visitors, architectural and aesthetic benefits for the beauty of the city that can provide benefits in the form of recreational and tourist spaces for the community. The existence of RTH will improve air quality and comfort in densely populated areas. The method used is to calculate the Temperature Humidity Index (THI). The research aims to analyze the temperature and humidity that affect the comfort level of GOS in Gedong Tataan. Data is taken in October 2023. The results showed that the highest temperature was found in Gedong Tataan Park, which was 34.4 oC, and the lowest temperature was found in Jejama Sidototo Park, which was 25.8 oC. The difference in temperature and air humidity in the two RTHs in Gedong Tataan District is caused by differences in the composition of vegetation types. The diversity of vegetation types can reduce air temperature and increase humidity to provide comfort in both GOSs.

Abstract

The government has an important role in implementing conservation partnerships as an effort to balance sustainable forest utilization. The purpose of this study is to analyze the role of government in implementing the conservation partnership program in KTH Sumber Sari, Pesawaran Regency. The collected data were analyzed descriptively and the measurement of the government's role used a Likert scale. The results showed that the government's role in implementing the conservation partnership was considered to be quite instrumental with an average overall score of 3.22 or 80%. However, there are several aspects that need improvement, especially in involving farmers in the planning process, monitoring and evaluation activities, and responding to constraints faced by farmers. The government is expected to improve collaboration with forest farmers to ensure the implementation of conservation partnerships can run more effectively and sustainably.

Abstract

Eucalyptus pellita is a type of fast-growing plant (fast-growing species). The advantage of this plant is that it is a short rotation or fast-growing plant, with fewer disease attacks. The benefits of the plant are quite numerous and it has high economic value. Considering that the optimal light intensity for eucalyptus seedling growth is not yet known, it is necessary to test the effects of various light intensities using shade in the form of paranet. This research was conducted using a factorial Completely Randomized Design (CRD) with a split-plot experimental pattern consisting of 4 treatment levels. Each treatment was repeated 3 times, The results of the study on the effect of NPK fertilizer and light intensity on the growth of eucalyptus seedlings indicate that the interaction of 5g NPK fertilizer per seedling and 100% light intensity is a better treatment compared to other treatments. This is suspected because eucalyptus is a plant that requires sufficient light intensity to experience the growth of eucalyptus seedlings. The growth of eucalyptus seedlings is influenced by light intensity, which supports the increase in height, stem diameter, and number of leaves. Based on the results of this study, it can be concluded that the treatment with NPK fertilizer and light intensity has a significant effect on increasing stem diameter. In the treatment P2C0, which is NPK fertilizer 7g/seedling and light intensity 100%, there is no significant difference compared to treatments P1C0 and P3C0, which are NPK fertilizers 5g and 9g/seedling at 100% light intensity.

Abstract

The sawmill industry produces sawdust waste that is still not utilized optimally. Currently, the processing of wood waste in the form of sawdust is still carried out in an inappropriate way such as disposal into rivers and incineration, even though the waste has the potential to be used in various products of economic value such as oyster mushroom planting media. For this reason, the purpose of this study is to find out the percentage of sawdust waste that can be used and analyze the level of financial feasibility of developing an oyster mushroom cultivation business. The data collection methods used are observation, interviews, and documentation with data analysis using percentage analysis and economic feasibility analysis using NPV, IRR, BCR, Payback Period, and sensitivity analysis criteria. The results showed that the percentage of sawdust waste utilization reached 89.60% (3,000 kg) of the total production, with details of 44.80% (1,500 kg) for oyster mushroom planting media, 29.90% (1,000 kg) for cowshed floor mats, and 14.90% (500 kg) for fertilizer. The analysis of the financial feasibility of the business is considered feasible to be developed, with an NPV of IDR 43,336,430, IRR of 49.6654%, BCR of 2.64, and a Payback Period of 2 years and 20 days. For this reason, efforts to utilize sawdust waste need to be increased.

Abstract

A tree is a woody plant with a main trunk and branches that grow upwards. Trees play an ecological role as carbon reserves and habitats for various fauna. This research is important to provide references related to tree diversity and natural forest ecosystems as a basis for policy-making to support ecosystem sustainability. Research on tree vegetation has never been conducted in the Girimanik Wonogiri Natural Forest Area, therefore, this study aims to observe the structure and composition of trees in this area. Data was collected using the one-hectare plot method, with 25 plots each measuring 20 x 20 cm. To meet the plot criteria for vegetation analysis, plot placement was carried out using the purposive sampling method. The results of this study show that the Girimanik Natural Forest Area has 40 species from 24 families, with the tree species having the highest importance value index are Quercus lineata and Ficus padana. The plant with the largest diameter is Trema orientalis. Natural forests have the highest tree diversity compared to artificial forests or agroforestry systems.

Abstract

The presence of birds can indicate whether the environment supports the life of an organism or not because it has a reciprocal and interdependent relationship with its environment. The diversity and abundance of bird species can indicate how the area is doing. This study aimed to determine birds' diversity, richness, evenness, dominance, feeding groups, and conservation status in the Simpang Rusa Ecosystem Recovery Area (SRERA). Data collection was done by direct observation in the field using the point count method. A total of 47 bird species from 24 families with a species diversity value (H') of 3.11 in the high category, species richness value (R) 7.62, species evenness value (E) of 0.8 in the good category, and species dominance (C) of 0.07 in the low category. 6 feeding groups were identified, namely insect eaters (53%), fruit eaters (18%), animal material eaters (12%), fish eaters (7%), seed eaters (6%) and nectar eaters (3%). Four protected bird species were found, namely Elanus caeruleus and Spilornis cheela, Gorsachius melanolophus and Rhipidura javanica. Based on the IUCN Redlist, there are two bird species with Near Treatened status, namely the Phaenicophaeus diardi and Cyornis turcosus, one species with Vulnerable status, namely the Acridotheres javanicus, and 42 other species with Least Concern status. Based on CITES, two bird species have Appendix II status. Annual monitoring is needed to monitor the population and mitigate threats as a conservation effort.

Abstract

Wood extraction using human power is a popular wood extraction technique in private forest harvesting in Indonesia. The method is used for transporting short logs over a short distance in flat or steep areas, which do not have adequate transport roads. The study aimed to analyze time consumption, productivity, and costs of wood extraction using human power in private forests. The study was conducted in a private forest in Probolinggo, East Java. The study was carried out in two cutting blocks. The first cutting block was 50 m from the landing, while the second was 250 m. The data collected included working time, productivity, and costs of wood extraction using human power. Working time data were obtained through video analysis, diameter, and tree height data were collected through direct measurements in the field, and cost data was obtained through direct measurements and interviews. Work time analysis was carried out for 73 cycles for cutting block 1 and 57 cycles for cutting block 2. The results showed that the workers spent most of their time on loaded trips, followed by empty travel, and for personal purposes. The lowest working time was placing and arranging the wood at the landing. The average wood extraction time per cycle was 4.49 minutes for a skidding distance of 50 m and 16.30 minutes for a skidding distance of 250 m. The results showed that the productivity of wood extraction using human power varied from 0.45 to 1.75 m3/hour. The cost of wood extraction using human power in private forests was IDR. 13.33/m3 for a skid distance of 50 m and IDR 51.85/m3 for a skidding distance of 250 m

Abstract

Geothermal Power Plants are one of the geothermal energies that can be used as a source of electricity. One of the geothermal powers in Lampung is the Ulubelu PLTP located in Tanggamus Regency. As an energy-producing agency, Ulubelu PLTP also contributes to preserving flora and fauna in their work area. This is shown through the planting of several types of wood plants to improve the flora in their work area. This study aims to record the types of plants that exist, the abundance of their types, climatic and edaphic factors, as well as recommendations for types that can be used for the enrichment of flora types in the Ulubelu PLTP work area. The vegetation analysis method used to collect flora data is a census method divided into 5 observation lines. The dominant and codominant types found at the tree level are Acacia mangium and Erythrina variegata, at the pole level Leucaena leucocephala and Toona sureni, at the pile level Gliricidia sepium and Syzygium myrtifolium, and at the lower plant level are Imperata cylindrica and Mikania micrantha. In addition to commercial types, some types have the potential to be invasive in the Ulubelu PLTP. The study also recommends that plant species be restored to increase species diversity and vegetation density. The types recommended for restoration based on vegetation analysis data are those that have aesthetic value, those that produce fruit or flowers that can present animals, and the protected types or types that can be used in addition to their wood.
