Abstract

The Ministry of Environment and Forestry designates forest and land rehabilitation (RHL) initiatives as a top priority in national policies. Forest and land rehabilitation refers to the deliberate actions taken to restore, preserve, and enhance the functionality of forests and land. Therefore, this study is to assess the viability of cultivating RHL plants. The methodology employed is the observation approach, which entails gathering data firsthand at the specific site. Plant area measurements are conducted on the physical planting area, quantified in hectares, and then compared to the intended plant area as specified in the design. Plant evaluation and assessment is conducted using the Systematic Sampling with Random Start approach, which involves randomly selecting the first measurement plot and then systematically selecting successive measuring plots. The sampling utilised a 5% interval. Rectangular measurement plots are formed with dimensions of 40 meters by 25 meters, resulting in an area of 0.1 hectares. The number of measuring plots can be determined by multiplying the percentage of interest (5%) by the plot area (in hectares) and then dividing by the area of each measuring plot (in hectares). This calculation results in a total of 43 measuring plots. The research findings indicate that the success rate of plant development varies between 76.33% and 77.17%, with an average value of 76.62%.

Abstract

This research aims to analyze the level of erosion in various planting patterns of agroforestry systems implemented by the community in Lupia Village, Kabangka District, Muna Regency. The background of this research is based on the issue of land degradation due to population pressure on forest areas, which prompts the need for alternative approaches such as agroforestry. The research was conducted from June to July 2012 using field study and laboratory analysis methods. The collected data includes information on rainfall, slope, soil texture and structure, as well as the types of planting patterns used. The calculation of erosion rates was done using the USLE (Universal Soil Loss Equation) method. The research results show that the agroforestry planting pattern consisting of a combination of Teak-Banana-Papaya (with an 8% slope) produced the lowest erosion rate of 17.40 tons/ha/year, while the combination of Teak-Long Beans-Cocoa (with a 12% slope) showed the highest erosion rate of 34.31 tons/ha/year. All observed planting patterns resulted in erosion levels exceeding the tolerance threshold, thus not reflecting a sustainable system. Therefore, it is necessary to apply soil conservation techniques to support the sustainability of the agroforestry system in the area.

Abstract

The Tesbatan region, located in the Amarasi District of Kupang Regency, is rich in biodiversity and local cultural heritage, making it a potential hub for ecotourism development. This study aims to develop a comprehensive strategy for biodiversity conservation and creative economic ecotourism to promote sustainable growth in the region. The primary objective is to combine conservation efforts with local economic empowerment through creative industries such as handicrafts, traditional cuisine, and cultural performances. This research utilizes a systematic approach that includes field surveys, literature reviews, and the application of tools like MICMAC, MACTOR, and ISM for data analysis. Data was collected through observations, interviews, questionnaires, and Focus Group Discussions (FGDs) with local stakeholders. The study identifies key variables, influences, and stakeholders involved in the management of biodiversity and ecotourism. The findings suggest that integrating biodiversity conservation with ecotourism and creative economic activities can enhance both environmental sustainability and local community welfare. The proposed strategies involve strengthening local institutions, promoting participatory resource management, and developing integrated ecotourism attractions. In conclusion, this research provides a practical framework for managing Tesbatan’s natural and cultural assets sustainably, fostering both environmental protection and socio-economic development.

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

Infrastruktur kelautan seperti fasilitas dan kapal sangat penting di Indonesia karena posisinya sebagai negara maritim. Kayu untuk tujuan infrastruktur kelautan ini umumnya bersumber dari hutan alam, sehingga perlu ada alternatif dari hutan tanaman untuk pemenuhan kebutuhan kayunya. Kayu nangka dari hutan rakyat dipilih sebagai objek penelitian ini karena adalah jenis kayu yang digunakan dalam penelitian ini. Kayak ini dipilih karena memiliki keawetan yang baik. Tujuan dari penelitian ini adalah untuk mengidentifikasi serangan marine borer terhadap kayu nangka pada berbagai kedalaman laut dan menentukan sifat fisis mekanis kayu setelah direndam di laut. Penelitian dilakukan di Pulau Rambut, dengan contoh uji 24 buah berukuran 30 cm x 5 cm x 2,5 cm. Semua contoh uji disusun dengan tali tambang dan direndam di laut selama tiga bulan pada kedalaman 5 cm di atas permukaan laut, serta 10 cm dan 42 cm di bawah permukaan laut. Hasilnya menunjukkan bahwa contoh uji yang disusun pada kedalaman 5 cm di atas permukaan laut sangat tahan terhadap marine borer, dan contoh uji yang disusun pada kedalaman 10 cm dan 42 cm di bawah permukaan laut tahan terhadap marine borer. Nilai MOE untuk kontrol adalah 79994 kg/cm2 dan turun menjadi 48714 kg/cm2 setelah direndam di laut; MOR adalah 1329 kg/cm2 untuk kontrol dan turun menjadi 672 kg/cm2 setelah direndam di laut. Berat kayu kontrol adalah 0,55, tetapi beratnya sedikit turun menjadi 0,51 setelah direndam di laut. Nilai mekanis MOE dan MOR antara contoh uji kontrol dan setelah direndam berbeda nyata. Namun, kedalaman perendaman contoh uji tidak berpengaruh nyata terhadap nilai mekanisnya.
