Abstract

The lack of community involvement poses a significant obstacle that may impede the achievement of success in the conservation partnership program between the Mount Merbabu National Park (MMNP) authority and the local community. This study serves a purpose and presents a new approach by investigating the impact of human and social capital on community engagement in the conservation partnership program, with the mediation of the extension worker’s role. This location was determined using a purposive method, focusing primarily on three villages surrounding MMNP, Indonesia. The sampling technique employed was simple random sampling, where 30 respondents were chosen from each village, resulting in a total sample size of 90 respondents. This study examines the variables using the Structural Equation Model (SEM) - Partial Least Squares (PLS) approach. Social capital has a positive and significant impact on community engagement through forestry extension workers, while human capital does not affect community conservation partnership involvement through the same workers. This study recommends enhancing social capital to increase community participation in conservation initiatives. Forestry extension officers should improve communication, social networks, and environmental competency to encourage greater community involvement in environmental protection. Keywords: community engagement, extension workers role, forest conservation, human capital, social capital

Abstract

Increasing ambient temperatures due to climate change have significantly impacted workers’ physical and mental workloads, affecting their health and safety. Promoting precautionary behaviors, especially among outdoor workers, is an effective strategy widely recommended for addressing these challenges. Precautionary behavior represents an essential protective mechanism that can be adopted at the individual level. This study explores the connections among Occupational Safety and Health (OSH), risk perception, and precautionary behavior. Descriptive statistics and Structural Equation Modeling with the Partial Least Squares approach were used to analyze the data. This study was conducted at two forest management units in Central Java and East Java, Indonesia, where daily air temperatures are relatively high. The research involved 100 respondents, comprising 50 indoor and 50 outdoor workers. The findings of this investigation reveal that OSH-related knowledge among indoor workers predicts their precautionary behavior. Nevertheless, according to the model, attempts to improve precautionary behavior through knowledge enhancement are estimated to be unsuccessful among outdoor workers. Nonetheless, OSH-related knowledge can facilitate workers in developing a more realistic perception, especially regarding the “dread risk factor” among forestry workers, which can positively impact their precautionary behavior.

Abstract

The mangrove ecosystem faces significant challenges, as its quality and quantity are threatened with decline. This study aimed to analyze the mangrove density and macrobenthos diversity in the Ampekale Ecotourism Village, Indonesia. This research utilizes remote sensing image analysis through the Normalized Difference Vegetation Index (NDVI) method. Complementary ground-check surveys were conducted to ascertain the density and diversity of mangrove and macrobenthos species. The overall mangrove density in the Ampekale area was relatively high, with some areas displaying moderate density. The sequence of mangrove species, from most common to least common, includes Rhizophora mucronata, Avicennia marina, Avicennia alba, Rhizophora apiculata, Sonneratia alba, Bruguiera gymnorhiza, and Acanthus ilicifolius. The most prevalent macrobenthos belong to the Crustacea class, such as Uca sp., Sesarma, Metaplax sp., and Scylla serrata. Moreover, the most diverse macrobenthos belong to the Gastropods class. The distribution of this biodiversity depends on their location (coastal or inland), tidal fluctuations, and river estuaries. Mangrove ecosystems situated in estuaries with high densities exhibited elevated macrobenthos abundance. This correlation suggests that areas characterized by dense mangroves also harbor stable ecosystem conditions with abundant macrobenthos. In contrast, ecosystems featuring lower biodiversity demonstrated reduced stability. These findings contribute valuable insights into the conservation and sustainability of mangrove ecosystems. Keywords: ecotourism, macrobenthos, mangrove density, mangrove ecosystem, NDVI

Abstract

Lampung is the third largest producer of nutmeg (Myristica fragrans) in Sumatra Island, Indonesia. Most nutmeg essential oil refining industries in Lampung process nutmeg seeds, but not many distill nutmeg leaves. Therefore, it is necessary to identify the chemical compounds of nutmeg essential oil to determine the potential for further processing products and the quality of nutmeg essential oil. The leaf essential oil samples were obtained from a refining industry in Pesawaran, Lampung, Indonesia. The chemical compounds of the essential oils were identified using gas chromatography-mass spectrometry. Nutmeg leaf essential oil quality was then evaluated according to SNI 06-2388-2006 as standard testing for nutmeg oil. The data were then analyzed descriptively. The results identified 28 active compounds in nutmeg leaf essential oil. Compounds with high relative abundance were streptamine (76.46%), aquinolizine (4.67%), boron (3.73%), kaurene (2.03%), pyrrole (1.95%), and naphthalene. There were also terpenoid compounds that produced aromas, such as guaiol, borneol, cedrene, cubenol, and spathulenol. The quality assessment of leaf nutmeg essential oils also fulfilled the requirement of SNI 06-2388-2006. However, the optical produced rotation towards the left, namely -9.48°, and a specific gravity of 0.87, less than the SNI 06-2388-2006 requirement of 0.88. Nutmeg leaf essential oil has the potential to become a raw material for health and beauty products. Keywords: agroforestry, essential oil, nutmeg leaves, streptamine, terpenoid compounds

Abstract

Cuscus (Spilocuscus maculatus) in captivity that were given a dominant fruit diet needed additional feed from their natural habitat because of the higher nutritional potential and fiber components. This study aims to determine the palatability of cuscus to the feed based on organic value. An experimental method was used, consisting of 4 treatment groups: 100% banana (Musa paradisiaca) as control, 70% banana mixed with 30% matoa (Pometia pinnata) leaves, 70% banana mixed with 30% ironwood (Pongamia pinnata) leaves, and 70% banana mixed with 30% crickets (Gryllus bimaculatus). The results showed that banana was the most preferred feed ingredient, either alone or as a supplementary feed mixture. In terms of quantity, its mixture with matoa leaves had a higher consumption level than ironwood leaves and crickets. The consumption level of organic matter was higher in the treatment with 100% banana than in other treatments. This information will help support ex-situ and in-situ conservation programs formulated by the government and other parties, including the community. Keywords: cuscus, feed, organic matter, palatability, Spilocuscus maculatus

Abstract

The microfibril angles (MFAs), relative crystallinity index (RC), and crystallite width (CrW) of compression wood (CPW), lateral wood (LTW), and opposite wood (OPW) in Agathis (Agathis loranthifolia) and Sumatran Pine (Pinus merkusii) stem wood were observed and compared to obtain valuable information on wood quality for effective utilization. The iodine staining method and optical microscopy were applied to measure the MFA in the tangential section. RC and CrW were analyzed with an X-ray diffraction technique. CPW had the largest MFA and the smallest RC in both species. In Agathis, LTW and OPW had comparable MFA, RC, and CrW, whereas the CrW of CPW was the smallest. In Sumatran pine, there was a significant difference in MFA and RC between LTW and OPW. CPW, LTW, and OPW showed comparable CrW. The MFA decreased and RC increased from near the pith to bark in both species. The CrW increased from near the pith to the bark of Sumatran pine, whereas it was constant in Agathis. In conclusion, MFA and RC could be used to identify CPW, LTW, and OPW in both species. There were distinctive MFA and RC properties between reaction wood in both species.

Abstract

Studying leaf trait variation and relationships along elevational gradients will enhance our understanding of how plants respond to changing environmental conditions. Thus, we analyzed the leaf traits variation in ecologically and economically important Parashorea malaanonan and the potential influence of environmental covariables (rainfall, relative humidity, and air temperature) on leaf traits along an elevational gradient in Mount Makiling Forest Reserve (MMFR). Three sampling sites were selected based on elevation, i.e., low (400–500 masl), mid (500–600 masl), and high (> 600 masl). The leaf samples were collected from seedlings, saplings, and adult trees of P. malaanonan. There was no significant variation in most of the measured leaf traits, leaf area (LA), specific leaf area (SLA), leaf thickness (LT), leaf length-to-width ratio (L:W) across sampling sites, except vein density (VD). The SLA and LT at high elevations are significantly and negatively correlated (r2 = 0.7396). The environmental covariables had a significant (p < 0.05) impact on the leaf traits of P. malaanonan. The observed variation in some leaf traits may have been influenced by the elevation gradient and its associated environmental conditions. Thus, P. malaanonan may have developed adaptive mechanisms to cope with the changing environment.

Abstract

Mount Merbabu National Park (MMNP) is a conservation area that provides environmental services (water) to surrounding villages spread across its area; however, the community has not realized its essential role. The study aims to calculate the economic benefits of water environmental services in MMNP, which the surrounding community utilizes for household needs. Primary data collection was conducted by interviews using structured questionnaires. Samples were determined using the purposive sampling method on 39 MMNP water sources. Data analysis was carried out by calculating public perceptions of water use and assessing willingness to pay for water use for household needs. The study results showed that the economic value of household water is IDR 10,700,681,768 per year, with the value of the willingness to pay the community for water utilization and conservation IDR 4,360,408,000 per year. The total economic benefit of water in the MMNP area is IDR 15,061,089,768 per year. The views and dynamics of water source management on Mount Merbabu are diverse. The water on Mount Merbabu has been a blessing, a source of conflict, a source of life, and can be a tool of political intimidation. It is necessary to make the public aware of water sources, recharge areas, and better water utilization because water has economic value.

Abstract

One of the wood sources in Indonesia is derived from private forests managed with agroforestry systems. The harvesting operation in these forests will produce harvesting residues. The study aimed to quantify the harvesting residue volume and to construct a prediction model for harvesting residue volume in a private forest managed with an agroforestry system. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The method employed for quantifying harvesting residue was a whole-tree method. The harvesting residue was classified into stumps, butt ends, top logs, and branches. Harvesting residues with dbh >= 4 cm were measured after harvesting. The best model was selected based on the Root Mean Squared Error and the adjusted coefficient of determination values.   The number of sample trees was 31 trees, which were chosen by farmers to be felled. The study found that the harvesting residues were 6% of the total harvested volume. The harvesting residue was predominantly the stumps. The best model for estimating harvesting residue volume in agroforestry private forests was V = 0.042VolTot1.248. The study concluded that harvesting operations in private forests managed with agroforestry systems produced a small number of harvesting residues. The harvested volume was the most significant indicator for estimating the harvesting residue volume.     Keywords: agroforestry, harvesting residue, private forests, predicting models

Abstract

Agroforests in many tropical countries have long been acknowledged as substantially necessary to contribute to biodiversity conservation and community livelihood. The importance of agroforest biodiversification is now overlooked and replaced by a simplified structure due to the impact of agricultural commercialization. Land use changes have occurred in the Upper Citarum Watershed over time, converting traditional agroforests into monoculture plantations at the expense of their socio-ecological function. This paper aimed to analyze land use change dynamics and the effect of biodiversity loss on the socio-economy aspect of the rural agricultural landscape in the Upper Citarum Watershed. We conducted a survey of 95 respondents of community farmers in the agricultural landscape in Sukapura and Resmi Tingal Village using questionnaire guidelines and direct interviews to gather information. There was a significant decrease in plant diversity in some plot agroforests, which, in the previous study, was dominant to be reduced even to local extinctions. The results also show that the farmer poverty index according to BPS criteria is 12.63% of respondents who are below the poverty line. Our results imply that preserving mixed-garden (talun) patches in a landscape dominated by cash-crop gardens is one of the strategies that could conserve landscape biodiversity and increasingly a sustainable livelihood. Keywords: agriculture commercialization, agroforestry, land use change, poverty index, rural development
