Abstract

The reason for the low productivity of cashew in the Indonesian province of West Nusa Tenggara is that they are never cared for and the land between the cashew tree rows is not intensively cultivated. The first factor is the type of organic fertilizer: cow, horse, and chicken manure; a mixture of cow + horse manure, cow + chicken manure, and horse + chicken manure. The second factor is the dosage ratio of organic fertilizer: 35 tons + NPK 0 kg ha-1, 25 tons + NPK 250 kg ha-1, 15 tons + NPK 500 kg ha-1, and 0 tons + NPK 750 kg ha-1. The application of organic fertilizer from a mixture of cow and chicken manure at a dose of 15-25 tons + NPK 250-500 kg ha-1 significantly increases soil fertility status and reduces the rate of soil erosion. When applying the best type of organic fertilizer, the dosage ratio of 35 tons + NPK 0 kg ha-1 and 0 tons + NPK 750 kg ha-1, the effect is not significantly different for all parameters. Applying a dose of 15 to 25 tons per hectare can replace the role of NPK fertilizer by 33.33 to 66.67% of the 750 kg per hectare dose and significantly increase the cattle breeding capacity of cashew plantations by up to 5,875 livestock unit hectare-1 season-1

Abstract

Sajang Village, located near Mount Rinjani National Park in West Nusa Tenggara, has significant potential for agro-tourism due to its biodiversity, traditional culture, and unique yard-based agricultural landscapes. Despite this potential, previous initiatives have overlooked the critical role of tourist perceptions and the conservation of home yards in shaping effective agrotourism strategies. This research aims to incorporate tourist preferences and yard conservation into the sustainable development of agro-tourism in Sajang Village. This descriptive qualitative study, conducted in June–July 2025, surveyed tourists and used SWOT analysis to evaluate the village’s strengths, weaknesses, opportunities, and threats. Findings reveal that 54.7% of tourists consider yard plant diverse, 24.6% rate it as very diverse, and 20.7% as quite diverse. Fruit and vegetable plants dominate the yards (86.7%), with ornamental plants comprising 13.3%. All surveyed tourists supported developing Sajang Village for agro-tourism, valuing its natural diversity, authentic experiences, and traditional use of home yards for ornamental, vegetable, and spice plants. The research underscores the importance of diversifying tourism activities such as fruit picking, coffee plantation tours, and local product promotion alongside conservation measures that prioritize native species and maintain traditional yard layouts. Collaboration among communities, authorities, and stakeholders is crucial for infrastructure and effective promotion. Integrating visitor perspectives with yard conservation offers a replicable model for sustainable agro-tourism, strengthening both local livelihoods and environmental stewardship.

Abstract

The Gorontalo region is one of the regions on the island of Sulawesi that is quite significant in terms of tectonic activity due to earthquakes. This is because Gorontalo is located in a tectonic environment, with a subduction zone in the Sulawesi Trench north and the Balantak Thrust and Batui Thrust south of the Gorontalo Fault. To further understand Gorontalo's seismic activity, we conducted a seismotectonic analysis in the form of identifying the number of earthquakes from 1994 to 2025, interpreting the results of the focal mechanism distribution by classifying them in the Kaverina diagram, and analyzing the results of earthquake hypocentre relocation from 2015 to 2022. The study results show that 2.317 earthquake events over 30 years spread across all areas of Gorontalo, categorised as shallow, medium, and deep earthquakes. The Gorontalo area is dominated by reverse faulting focus mechanisms, which are commonly found at shallow to intermediate depths. This is interpreted as being due to the presence of a subduction zone. A different situation occurs at deep depths, where the focal mechanism is normal faulting, indicating the presence of extensional forces due to the rollback slab process. The distribution of earthquake mechanisms also shows that a combination of strike-slip and reverse mechanisms occurs around active fault zones. In contrast, strike-slip mechanisms with standard mechanisms are more dominant in extensional zones.

Abstract

This study aims to analyze the learning profiles of students with intellectual disabilities, focusing on their learning styles in studying the basic laws of chemistry using e-LAPD based Liveworksheets. The participants were three students with intellectual disabilities from SMAN 10 Surabaya. A mixed-method approach with a concurrent embedded model was employed. Qualitative data were collected through interviews and observations and analyzed using Nvivo 11 software, while quantitative data were obtained from pretest and posttest results and analyzed using bar charts and N-Gain scores to measure improvement in learning outcomes. The quantitative data also supported the qualitative analysis of the relationship between learning style tendencies and learning outcomes. The results show that student DA exhibited a kinesthetic learning style, whereas E and RY demonstrated visual learning styles. Students engagement with e-LAPD activities reflected variations in learning style preferences. Quantitative analysis indicated an increase in learning outcomes, with N-Gain scores categorized as high. Therefore, a learning style that matches students characteristics can enhance learning outcomes. Based on these findings, it can be concluded that e-LAPD based liveworksheets can assist in analyzing learning profiles, particularly learning style tendencies that influence the learning outcomes of students with intellectual disabilities.

Abstract

Inflammation is a protective response of the body caused by tissue damage due to abnormal physical conditions, harmful chemical compounds, or microbiological agents. The protein denaturation method for anti-inflammatory testing aims to determine whether the ethyl acetate and ethanol–water fractions of cashew (Anacardium occidentale Linn) stem bark exhibit anti-inflammatory activity using the protein denaturation method, and to determine the IC₅₀ values of both fractions. The anti-inflammatory activities of the ethyl acetate and ethanol–water fractions, along with the positive control, were tested using a UV–Vis spectrophotometer at concentrations of 100 ppm, 200 ppm, 400 ppm, 800 ppm, and 1600 ppm. The results showed that the ethyl acetate fraction of cashew stem bark (Anacardium occidentale L.) had an IC₅₀ value of 531.74 µg/mL, the ethanol–water fraction had an IC₅₀ value of 101.31 µg/mL, and the positive control had an IC₅₀ value of –70.85 µg/mL. These findings indicate that the ethanol–water fraction exhibited moderate anti-inflammatory activity, while the ethyl acetate fraction showed weak activity.
