Abstract

The Bissoloro Educational Forest, covering an area of 75.12 hectares in Gowa Regency, South Sulawesi, serves as a natural research site under the stewardship of Muhammadiyah University of Makassar. Although the forest holds considerable ecological value, comprehensive and systematic data on its faunal diversity are still limited. This study was conducted to explore and evaluate the composition, richness, and community structure of fauna within the area, focusing on three major groups: mammals, reptiles, and birds. Data collection for mammals and reptiles was conducted through both direct sightings and indirect indicators, while avian data were obtained using a 1,700-meter line transect with 17 observation points over a three-day survey period. A total of 39 faunal species were recorded, comprising 4 mammal species, 10 reptile species, and 25 bird species. Among the bird species, Pycnonotus aurigaster was identified as the most dominant, with the highest Importance Value Index (INP) of 38.19%, supported by a relative frequency of 19.61% and relative dominance of 18.58%. The overall bird community diversity, as measured by the Shannon-Wiener index (H'), was 2.59, reflecting a moderate level of biodiversity. The occurrence of endemic and protected species, including top predators and nectar-feeding birds, indicates that essential ecological functions such as pollination and food web dynamics are still maintained. These results highlight the ecological importance of the Bissoloro Educational Forest and its role as a vital site for biodiversity conservation, environmental education, and long-term ecological monitoring in alignment with the Merdeka Belajar Kampus Merdeka (MBKM) framework.

Abstract

Water is a vital resource, yet its quality is increasingly affected by climate change and human activities. Seasonal variations, particularly between dry and rainy periods, may influence river water quality, with pH serving as a key chemical parameter. This study aimed to examine the effect of seasonal differences on river water pH levels using meta-analysis. The objective was to provide evidence of whether rainfall patterns significantly alter pH concentrations in tropical and subtropical regions. Relevant literature was collected from online databases using keywords such as “water pollution,” “dry season,” and “wet season.” Out of more than 40 studies, four articles with complete seasonal pH data were selected. Data were processed using OpenMEE software with a random-effects model, and the log response ratio (lnRR) was applied to compare pH values between dry (control) and rainy (treatment) seasons. The analysis revealed no significant seasonal differences in pH levels. The overall effect size was weak (–0.758), with the 95% confidence interval crossing zero. Heterogeneity among studies was high (I² = 80.325%), yet subgroup analyses by region, climate, and location confirmed consistent results. In conclusion, river water pH in tropical and subtropical areas remains relatively stable across seasons, influenced by steady climate conditions, well-mixed water bodies, and consistent vegetation. Broader datasets, especially from Indonesia, are needed to validate these findings.

Abstract

Bunder Grand Forest Park (Tahura) is a nature conservation area that plays a crucial role in maintaining the sustainability of biological resources and ecosystems in the Yogyakarta region. The development of Bunder Grand Forest Park is not only focused on ecological preservation but also contributes to strengthening Yogyakarta's identity as a center for environmentally conscious education and tourism. This study aims to determine the types of undergrowth, INP and its species diversity. This study was conducted using a quadrat sampling technique, using a double plot method. For observations used PU with a size of 1 m x 1 m. The results of research conducted in the Bunder Forest Park area, found 21 types of undergrowth, which are divided into 2 groups, namely non-grass plants and grass-type undergrowth, with the largest INP value obtained by the type of non-grass plant, namely the Bandotan plant (Ageratum conyzoides L.), with a value of 43.22%, and the grass-type undergrowth, namely the Elephant grass plant (Pennisetum purpuroides) with a value of 84.39% while the undergrowth with the lowest INP value, obtained by the type of non-grass plant, namely Lamtoro (Leucaena leucocephala), with a value of 3.15%, and the grass-type plant, namely the Grepak Grass plant (Paspalum conjugatum Berg.) with a value of 6.57%. In terms of diversity, non-grass understory plants are known to have moderate species diversity, while grass understory plants have low species diversity.

Abstract

The Pengulu Tribe in Limun District, Sarolangun Regency, Jambi Province, has long used the fruit of *Scaphium macropodum*—locally known as "merpayang" or "mempayang"—as a traditional medicine. *Scaphium macropodum* belongs to the Sterculiaceae family and has a broader distribution compared to its seven subspecies. This study investigates the ecology of *S. macropodum* to provide initial information on its use by the Pengulu Tribe, as well as the population and habitat conditions in Sarolangun Jambi's production forest. The study aims to estimate the population of *S. macropodum* in the forest and analyze the ecological factors influencing its habitat. Conducted between December 2023 and January 2024, the research utilized observation, interviews, and literature review methods, with data analyzed descriptively and qualitatively. Ecological factors were examined using the Importance Value Index (INP), diversity and evenness indices, community similarity index (Ward method), and Principal Component Analysis (PCA). The study identified 47 species from 18 tree families within the *S. macropodum* habitat. The dominant species in two research sites, APL NM and HA DM, were *Shorea parviflora* (meranti). At HL DT and APL DM, the dominant species were *Shorea multiflora* (squirrel coconut) and *Canarium* sp. (mosquito legs). The Shannon-Wiener diversity analysis indicated moderate diversity and evenness across the four sites. APL NM and HA DM had significant community similarity (90.81%), while APL DM had a lower diversity index compared to the other sites.

Abstract

Character development for students means working on the nature of the educational cycle and outcomes that lead to the development of students' personalities and honorable ethics in a comprehensive, coordinated and adjusted manner, according to skills guidelines. One of the problems that occurs at the local level and in the school climate is the low interest of the local community (including high school/mama level students) in the waste problem. The method used in this community service activity is the lecture or socialization method, direction and education by researchers to provide information to Hosana Private High School students about the importance of protecting the surrounding environment and the school. From the results of the socialization and presentation about air pollution and concern for the environment, it appeared that students were very enthusiastic about listening to the presentation from the resource person. After the presentation from the resource person, a discussion session was held on these two topics. From the results of the presentation about air pollution by the resource person to students, it shows that students' knowledge about environmental pollution is relatively good, this is obtained from the average test score carried out after the presentation of 78 obtained from 40 students. Hosana Private High School students have used public transportation to reduce air pollution. Some students use public transportation (angkot), accompanied by their parents and cycle, which is an effort to reduce air pollution. Likewise, the behavior of maintaining school cleanliness has been implemented by students. This can be seen when the socialization event is over, students clean the room and tidy up the room that has been used.

Abstract

Cinnamon is an herbal remedy proven to lower blood sugar levels in patients with type 2 diabetes mellitus (DM). Cinnamon contains coumarin, which reduces the blood sugar levels. This study aimed to determine whether administration of a higher dose of cinnamon could lower blood sugar levels in individuals with type 2 diabetes mellitus. Methods: This study employed a randomized controlled trial (RCT) design and was conducted at the Medan Denai Health Center from November to December 2023. Participants were randomly selected and divided into two groups: the intervention group, which received cinnamon extract (n= 15), and the control group (n= 15), which did not receive any treatment. The dose was 10 mg/day. Blood sugar levels were measured using a standardized instrument and data were analyzed using the Kruskal–Wallis test. Results, before receiving cinnamon extract, the average blood sugar level was 238,80 mg/dL in the intervention group and 225,33 mg/dL in the control group. After cinnamon extract administration, the intervention group showed a significant reduction of 127,73 mg/dL, whereas that of the control group remained at 222,20 mg/dL. Statistical analysis revealed a significant difference in the blood sugar levels following cinnamon extract administration (p< 0,001). In conclusion, cinnamon extract supplementation can help lower blood sugar levels in patients with type 2 diabetes mellitus.
