Abstract

Konservasi satwa liar secara eksitu, terutama bagi Gajah Sumatera, merupakan upaya penting dalam menjaga kelangsungan spesies yang terancam punah di Indonesia. Meskipun berbagai lembaga konservasi di Indonesia telah menerapkan teknik pemeliharaan eksitu, tantangan dalam meniru habitat alami dan memenuhi kebutuhan fisiologis serta psikologis gajah masih menjadi hambatan. Penelitian ini bertujuan untuk mengevaluasi manajemen teknik pemeliharaan Gajah Sumatera di Lombok Wildlife Park dan mengukur tingkat kesejahteraan satwa berdasarkan lima indikator utama kesejahteraan satwa yang ditetapkan oleh Persatuan Kebun Binatang Seluruh Indonesia (PKBSI). Metodologi yang digunakan meliputi observasi lapangan, wawancara, dan studi literatur, dengan analisis data untuk menilai pengelolaan kandang, pakan, kesehatan, dan reproduksi gajah. Hasil penelitian menunjukkan bahwa tingkat kesejahteraan Gajah Sumatera di Lombok Wildlife Park berada pada kategori baik dengan skor rata-rata 75,14, meskipun terdapat aspek yang perlu diperbaiki, seperti pengayaan kandang dan peningkatan fasilitas medis. Implikasi dari penelitian ini adalah perlunya perbaikan dalam fasilitas medis dan pengelolaan lingkungan kandang untuk meningkatkan kesejahteraan satwa, yang akan mendukung keberlanjutan program konservasi eksitu di Indonesia.

Abstract

Bio-charcoal briquettes are a promising alternative to fossil fuels, particularly when produced from biomass waste such as sawdust. This study investigates the effects of varying molasses adhesive concentrations (5%, 10%, and 15%) on the physical and chemical properties of bio-charcoal briquettes produced from sawdust. The briquettes were analyzed for density, moisture content, ash content, volatile matter, fixed carbon, and calorific value. Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were also employed to examine surface morphology and functional groups. The results showed that increasing molasses concentration led to higher density, moisture content, and fixed carbon content, while reducing ash and volatile matter content. The 10% molasses concentration provided the highest calorific value (5,420 cal/g). The results of testing using SEM with a magnification of 2000x, featuring a particle size of 60 mesh, revealed the morphology of the briquette surface with a regular arrangement of cavities. FTIR analysis confirmed the presence of O-H, C-H, and C=O groups, which contribute to molecular bonding. All samples met the SNI 01-6235-2000 standard for wood charcoal briquettes. The addition of 1% potassium chlorate further improved ignition and combustion. The findings demonstrate that molasses, as a low-cost and eco-friendly binder, effectively enhances the quality and energy performance of bio-charcoal briquettes. This study supports the development of renewable energy technologies from underutilized wood waste, promoting sustainable energy solutions and environmental conservation. Keywords: bio-charcoal briquettes, calorific value, combustion performance, molasses adhesive, sawdust waste

Abstract

The Suranadi Nature Tourism Park, a rather well-known location in West Lombok Regency, is one of the conservation places that the NTB administration is presently working on. Up until now, the Suranadi Nature Tourism Park region has been managed primarily with the goal of maintaining the territory's worth and purpose. Therefore, it is necessary to conduct research to determine the form and level of community participation in the management of the Suranadi Nature Tourism Park starting from the planning, implementation, to evaluation stages and to understand the factors that encourage the community to participate in the management of the Suranadi Nature Tourism Park. The method used in this study is a qualitative descriptive method. Data were analyzed using multiple linear regression, then tested the hypothesis, namely with the t-statistical test (t-test) and the F-test. According to the study's findings, there are three stages to the community's involvement in the management of Suranadi Nature Tourism Park: the planning stage, wherein community ideas and opinions are incorporated; the implementation stage, wherein involvement is split into two categories: labor and skill participation and property/investment participation; and the evaluation stage. With a score of 204, the degree of community involvement in the planning, execution, and assessment phases falls into the moderate range. According to the regression model derived for the elements impacting community engagement in Suranadi Nature Tourism Park management, it is separated into two categories: internal factors. Of these, income level, location distance, and employment account for 32.1% of the factors influencing community participation.

Abstract

Forests are one of the largest carbon dioxide absorbers, the forest's function as a carbon dioxide absorber causes an increase in greenhouse gases in the atmosphere, and carbon dioxide is stored in forest biomass. Forest development to increase carbon dioxide absorption can be carried out in state forest areas or private forests, which also include community forests. This research aims to estimate carbon stocks in the Tangga community forest (HKm) , in the Tangga HKm, Lombok utara, NTB. This research uses quantitative methods. The data collected is standing vegetation data. Standing vegetation data includes saplings, poles and trees by measuring diameter and height using purposive sampling collection techniques. Carbon stocks are estimated using the allometric equation formula. The total carbon reserves in the HKm Tangga obtained from each stand were 9.972,11 ton/ha. The highest carbon stock value is at the tree level with a value of 8.785,08 tons/ha, followed by the sapling level at 731,34 ton/ha, and the pole level at 455,69 tons/ha with the highest amount at the candlenut tree level (Aleurites moluccana) at 2.200,63 ton/ha and the lowest was the breadfruit (Artocarpus altilis) with a value of 1,96 ton/ha.

Abstract

The amount of water that enters the soil per unit of time is known as the infiltration rate, whereas infiltration itself is the process by which water flows into the soil, typically via rainfall. The purpose of this study was to determine the infiltration rate and the impact of infiltration and to formulate community efforts to control infiltration in the Ampang Riwo community forest. Determination of the research sampling point using purposive sampling. This study used 4 infiltration rate test points and 4 samples were taken for soil samples, namely Vegetation is not dense, very steep land (V1L1), Vegetation is not dense, rather steep land (V1L2), Vegetation is dense, very steep land (V2L1), and Vegetation is dense, rather steep land (V2L2). Measurements were taken using a double ring infiltrometer. The results of the study showed that there were 3 plots that had a fairly fast classification but had different infiltration rate values. The first plot V1L1 which had an infiltration rate value of 150 cm/hour, the second plot V2L1 had an infiltration rate value of 108 cm/hour, In the third plot V2L2 had an infiltration rate value of 186 cm/hour, in the plot V1L2 had a fast infiltration classification, an infiltration rate value of 204 cm/hour. This study there were 12 respondents, namely farmers who had cultivated land. The characteristics of the respondents included age and education level. Based on the results of the study, the perception of cultivators regarding the infiltration rate was obtained with a total of 13 respondents for 10 questions, on average answering strongly agree and agree. For strongly agree 30.77% and 69.23% agreed.

Abstract

The Javan gibbon (Hylobates moloch) is a primate endemic to Java Island that plays a crucial ecological role as a seed disperser and indicator of rainforest health. This study aims to analyze the daily behavioral patterns of the Javan gibbon (Hylobates moloch) at the ex-situ conservation site Lombok Wildlife Park to assess its expression of natural behaviors and welfare conditions. The research was conducted from September 2024 to January 2025 using the ad libitum observation method on a single male individual. Observations were carried out once daily from 09:00 to 17:00 for seven consecutive days each week. Data were analyzed descriptively and quantitatively through ethogram presentation and frequency percentage calculations of behavioral occurrences. The results showed a dominance of arboreal locomotion behaviors: brachiation occurred 126 times (38.77%), climbing 47 times (14.46%), and descending 43 times (13.23%). Foraging and social behaviors were moderately observed feeding 27 times (8.31%) and playing 26 times (8.00%) while self-maintenance (grooming) occurred 13 times (4.00%) and resting 15 times (4.62%). Excretion frequency was low: urination 6 times (1.85%) and defecation 2 times (0.62%). These findings indicate that the enclosure structure supports natural arboreal behavior, but additional foraging stimulation and enrichment are needed to prevent boredom and enhance long-term welfare. Recommendations include improving environmental enrichment complexity, regular evaluation of vertical structures, and further research on Javan gibbon welfare standards in ex-situ conservation facilities.

Abstract

Green Open Space can be interpreted as a space that maximises the length of the path or what is called a grove. Green open space serves to balance the ecological conditions in an area so that there is a balance between the ecosystem and the development of development in the modern era. In line with this, the government also regulates RTH and makes regulations contained in a regulation and implements programmes aimed at fulfilling the proportion of RTH in the Regency / City, especially in Green Open Space (RTH) as a support for community comfort. Based on Law Number 26 of 2007 concerning Spatial Planning mandates that each city must have a minimum Green Open Space (RTH) of 30%, where the city area must be in the form of RTH consisting of 20% public RTH and 10% private RTH. This research aims to find out, describe, and analyse the implementation of the green open space arrangement policy in Giri Menang City Park. This research was conducted in Giri Menang City Park, Gerung District, West Lombok Regency, West Nusa Tenggara. This research uses purposive sampling technique for determining respondents and snowball sampling for selecting respondents. The variables used here are based on William N Dunn's theory and analysed using qualitative and quantitative analysis. The results showed that the policy implementation of the Giri Menang City Park was reviewed based on William Dunn's theory using 6 criteria, namely effectiveness, efficiency, adequacy and responsiveness, which were included in the high category while equity and accuracy were in the medium category.
