Abstract

The existence of components that did not represent the concept of ecotourism and the decline in the number of visits was very significant. This research evaluated tourism performance based on tourists’ perspectives to determine the components that need improvement. The respondents in this study were 100 tourists, who were obtained by applying the Slovin formula. This study used primary data collected through research questionnaires distributed to respondents. The research instrument was tested to ensure its validity and reliability. The collected data were analyzed using the Customer Satisfaction Index (CSI), Gap Analysis, and Importance-Performance Analysis (IPA). Petengoran Mangrove Tourism does not match tourists’ expectations. The attributes that become the main priority because their performance is considered not to have met tourists’ expectations are the availability and diversity of tourist activities, accessibility conditions, implementation of educational activities, and several facilities that do not meet tourist satisfaction, even though these components are what tourists highly expected. Keywords: customer satisfaction index, mangrove tourism, Petengoran, tourism performance, tourist perception

Abstract

Tree felling is an important component of the forest harvesting system. A skyline-assisted felling technique (locally known as the ‘sandat’ felling technique) is used in private forest harvesting in Probolinggo, East Java, Indonesia, as an alternative to the conventional felling technique. This felling technique is used in private forests planted with an agroforestry pattern. Private forest farmers have recognized the technique as an effective way to protect multi-purpose tree species, especially coffee plants, but the technique’s efficiency is not yet known. The study analyzed the costs and productivity of sandat felling techniques in private forests planted with agroforestry patterns in Probolinggo. Working time studies, branch-free height, and breast height diameter measurements were carried out to calculate felling costs and productivity. The present value cost function was developed to compare the costs of sandat felling techniques with conventional felling techniques. The study showed that the productivity of sandat felling techniques was lower than conventional felling techniques. In contrast, the operating costs of sandat felling techniques were higher than those of conventional felling techniques. The operating cost per m3 rose by 20%. Additional operating costs for sandat felling techniques were incurred for procuring ropes and installing and uninstalling skyline. The felling costs will decrease with the felling team's increasing experience and skill. Keywords: agroforestry, costs analysis, felling techniques, private forests, sandat felling

Abstract

Gall rust disease poses a significant threat to falcata (Falcataria moluccana [Miq.] Barneby & J.W. Grimes), particularly in different elevation ranges. This study aimed to assess the gall rust disease incidence and severity at low (0–200 masl), moderate (201–400 masl), and high (401–600 masl) elevations. Results showed a significant correlation between gall rust disease incidence and severity and elevation based on Spearman rho correlation analysis. Higher elevations were associated with increased gall rust disease incidence and severity. This suggests that environmental conditions specific to these elevations may aggravate gall rust development. Based on the findings, temperature and relative humidity, which vary with elevation, play a role in gall rust disease incidence. Conversely, light intensity significantly influences gall rust disease severity across elevation ranges. These findings signify the importance of elevation-related factors in disease management strategies in falcata plantations. By identifying the relationship between gall rust disease and elevation, this research provides insightful information that can be used to improve disease management strategies and create focused control measures. The results provide an in-depth understanding of gall rust disease dynamics and offer recommendations for reducing its impact. Keywords: disease incidence, disease severity, elevation, Falcataria moluccana, gall rust

Abstract

Forest land conversion has caused global climate change, reducing biodiversity and food security challenges. Climate change’s influence on food security must be anticipated promptly by adopting an adaptable agricultural cultivation system, such as agroforestry. The Bangka community is one of many that continue to practice agroforestry. In the Bangka community, agroforestry is known as kelekak. This research aims to learn about the history, variety of species, challenges, and conservation strategies of kelekak. This study's data was gathered through interviews, field observations, and literature studies. Kelekak is a woodland region historically used by the community to produce dryland rice (ume), which later became kelekak agroforestry land. Several fruit plant species are commonly found on kelekak land, including durian (Durio zibethinus), mangosteen (Garcinia mangostana), cempedak (Artocarpus integer), and ketapi (Sandoricum koetjape). The community utilizes various plant species in the kelekak as food, medicine, building materials, and firewood. Kelekak’s survival is threatened by land conversion to monoculture plantations, limiting community resource access. Efforts to revive the kelekak can be achieved through the Tri Stimulus Amar Pro-Konservasi approach by integrating natural, benefit, and religious willingness stimulus. Efforts to reinvigorate kelekak must begin immediately, with mapping activities for the remaining kelekak in the Central Bangka area to provide primary data for future kelekak development and local government regulations to conserve kelekak. Keywords: agroforestry, conservation, food, forest, kelekak

Abstract

Mitigation actions to address climate change are essential to prevent future adverse impacts, with woody species in forests playing a pivotal role in carbon storage, as exemplified by the agroforestry systems commonly practiced in community forests of Bogor Regency, which integrate woody species and crops. This study aimed to analyze changes in vegetation density using the Normalized Difference Vegetation Index (NDVI) approach, analyze stand structure and composition, and estimate above-ground carbon stocks in the agroforestry land of community forest in Tenjolaya Sub-District, Bogor Regency. The methods used were spatial analysis with NDVI, vegetation analysis, and carbon stock estimation using allometric and destructive methods. The plot size was 50 m × 50 m, totaling 21 plots. NDVI analysis resulted in low density (0.59–0.67), moderate density (0.67–0.78), and high density (0.78–0.85). This study found 178 plant species across 40 families, with Fabaceae and Myrtaceae being the most dominant. The carbon stock is 27.69 tons carbon/ha. Carbon stock is significantly influenced by tree density, number of species, and basal area values. A well-managed community forest has high ecological, economic, and social potential through the development of agroforestry, which can maintain biodiversity and environmental sustainability while storing carbon stocks. Keywords: above-ground carbon, agroforestry, community forest, normalized difference vegetation index, vegetation density

Abstract

Plant canopies can protect the soil surface from raindrops and rooting activities that cause changes in biophysical properties. A low infiltration rate will reduce the soil’s capacity to store water to be low, resulting in a high soil erodibility value. This research aims to obtain infiltration values on different land cover, analyze the effect of land cover on soil infiltration rate, and analyze the effect of soil infiltration rate on soil erodibility. The research includes exploratory, descriptive research with a purposive sampling method. The study results show an increased soil infiltration rate can reduce soil erodibility. The infiltration rate of 74-year-old mahogany land cover ranged from 1.94–3.03 cm/hour, 50-year-old mahogany 1.61 cm/hour, old pine 1.53–1.89 cm/hour, old tapped pine 1.54–3.43 cm/hour, young pine 0.48–1.60 cm/hour, young pine 0.37–0.61 cm/hour, and 5-year-old sonokelling 0.56–0.73 cm/hour. The highest infiltration value is in 74-year-old mahogany and the lowest in young pine. The highest soil erodibility value is in young tapped pine and the lowest in 50-year-old mahogany. Erodibility is the sensitivity of soil to erosion. It is easier to erode if its erodibility value is higher; conversely, erosion is less likely to occur if its erodibility value is lower. An increase in soil infiltration rate can reduce soil erodibility. Keywords: Horton method, land cover, Mount Bromo, soil erodibility, soil infiltration rate

Abstract

Coffee is commonly cultivated under agroforestry systems, including dry-field and homegarden. These systems were differentiated based on their proximity to the settlements, which might influence the species composition. This study aimed to observe plant composition, diversity, vegetation structure, and microclimate in coffee agroforestry systems and the physiological conditions of coffee. The experimental design was based on purposive sampling. A total of 100 nested plots were established in Glagaharjo and Balerante of Yogyakarta, each consisting of a dry-field and homegarden. Higher diversity and potential products were observed in dry-field agroforestry. There was no significant difference in microclimate between both systems. However, a significantly higher number of poles (p < 0.001) and trees (p < 0.001) in dry-field compared to homegarden contributed to lower light interception, higher humidity and temperature in dry-field, which could be associated with the higher physiological performance of coffee despite the non-significant difference between the systems (p > 0.05). Therefore, microclimate conditions under dry-fields were considered suitable for improving coffee growth performance.   Keywords: agroforestry, coffee, dry-field, eco-physiology, homegarden

Abstract

Cajuput (Melaleuca cajuputi Powell) plants are essential oil-producing plants that have ecological and economic benefits. The ideal pruning life is one way to optimize the productivity of cajuput stands. This study aims to analyze the productivity of cajuput stands at various age levels in Telawa Forest Management Unit by considering shoots, stem diameter, shoot diameter, biomass, and land suitability analysis. Data was collected by making three temporary survey plots by simple random sampling at 5, 9, 13, 17, and 21-year-old stands. The results showed that cajuput stands experienced increased productivity, as seen in stem diameter, shoot diameter, and biomass. In addition, the higher the stand density, light intensity, and humidity positively affect the total biomass, with an increase in the life of the stand. Based on the study’s results, the best cajuput productivity occurred at 17-year-old stands, with an average biomass of 1,031.43 kg/ha and an allometric equation of 18.40 kg. The decrease in cajuput productivity occurred at 21-year-old stands, 40% compared to the 17-year-old stands, and the 21-year-old stands have the lowest land index value. Despite the decline in productivity, the main effects still need to be studied over a more extended period. Keywords: biomass, cajuput, optimal lifespan, productivity

Abstract

The study uncovers the promising anti-termite properties of Eucalyptus pellita bark extract, a resource often discarded as industrial waste in the pulp and paper manufacturing industry. It investigates the anti-termite efficacy of various extracts from E. pellita bark and identifies the extract with the highest activity, followed by a comprehensive phytochemical analysis. Samples of E. pellita inner bark, outer bark, and mixed bark were ground into 40–60 mesh powder and subjected to extraction using soxhletation techniques with successive extraction in increasingly polar solvents (n-hexane, ethyl acetate, and methanol solvents). The anti-termite activity of these extracts was evaluated using no-choice bioassays to determine the termite antifeedant activity through the weight loss percentage of test samples and the mortality rate of Coptotermes sp. Furthermore, Py-GCMS analysis was conducted on extracts exhibiting the highest anti-termite activity to elucidate their chemical composition. The findings revealed that methanol extracts from all three parts of E. pellita bark exhibited the most potent anti-termite activity against Coptotermes sp., as evidenced by the highest mortality rate (100%) and cellulose paper weight loss of 9.57 ± 6.66 mg. These methanol extracts were predominantly composed of phenolic compounds, particularly condensed tannins, suggesting a potential breakthrough in termite control. The findings indicate that E. pellita bark may be a sustainable and eco-friendly alternative to chemical pesticides for termite control. Furthermore, its utilization may facilitate waste valorization in the pulp and paper industry, thereby supporting environmental sustainability and economic efficiency.

Abstract

Pongamia (Pongamia pinnata) is a non-food plant that has the potential to be developed as a biofuel because its seeds’ oil content is up to 40%. Therefore, it is necessary to study the characteristics of seeds for germination in relation to mass cultivation and information on oil content as a production consideration. This paper aimed to describe the sensitivity of pongamia seed moisture content to germination and its oil content and also to understand the seed category. Variations in moisture content were obtained from storing seeds at ambient temperature for up to 5 months. Moisture content, morphological characters, oil content, and germination rate were examined for each storage period. Data were analyzed using analysis of variance to determine the treatment effect. The results showed that storing seeds at ambient temperature caused a decrease in moisture content. A decrease in moisture content of 29.36% in the first month’s storage significantly affected the reduction of morphological characters and seed weight. Meanwhile, during the 2–5 months storage period, the decrease in moisture content was only 2–5% and did not affect seed length. Reducing moisture content (MC) increased oil recovery but was not statistically significant. The best germination rate was 84.67%, obtained from fresh seeds (MC of 46.64%); the germination rate decreased as the moisture content decreased during storage. Pongamia should be categorized as an intermediate seed based on the seed moisture content characteristics and germination test results. Keywords: germination, moisture content, oil content, Pongamia pinnata, storage
