Abstract

The prevalence of landslides has resulted in great losses, including the loss of human lives, the loss of property, and the disruption of natural ecosystems, especially in Enrekang District, Enrekang Regency. This study aims to identify landslide-prone areas and the level of landslide risk by using a landslide-prone map in Enrekang District. This study uses quantitative descriptive method techniques, spatial analysis with GIS analysis tools, and assessment analysis is carried out by multiplying the weight values and scores for variables such as slope, rainfall, soil rock type, and land use. The results of the study showed that three classes of vulnerability were obtained in Enrekang District, namely, high vulnerability with an area of 128.80 Ha, medium vulnerability with an area of 24033.26 Ha, and low vulnerability with an area of 3817.16 Ha.

Abstract

This community service activity is expected to increase the knowledge and insight of beef cattle farmers in Bamba Puang Village, Anggeraja District, Enrekang Regency, regarding artificial insemination (AI) technology. Through a series of education, farmers are given an understanding of the importance of choosing good feed, how to detect estrus in acceptors, and proper maintenance management to support the success of AI. This activity was carried out on December 13, 2024, attended by local farmers and organized by Thematic KKN students of Muhammadiyah Bone University. The results of this activity show that farmers increasingly understand important aspects in the implementation of AI, which is expected to increase the productivity of beef cattle. In addition, this activity is also expected to reduce negative issues circulating regarding AI, and encourage farmers to be more confident in adopting this technology. It is hoped that with further training from the government, farmers can be more experienced and successful in their livestock business.

Abstract

Along with the development of industry and the increase in population, the need for chilies has also increased. This shows that more than half of the chilies that have been harvested have the potential to be wasted or not utilized optimally. So the dryer designed and made is a type of bulb heat-based dryer, namely a chili dryer that can use heat energy from the light rays of the bulb. With this dryer, it is hoped that there will be an increase in production capacity. Apart from that, the product obtained will be of good quality, namely having relatively clean chili quality. The research design used in this research is to use one treatment, namely for 10 hours from 08:00-18:00 and testing the specified parameters at a time interval of 120 minutes. In this research, the method used was an average calculation with one treatment repeated 3 times, symbolized P1= chili product 1, P2= chili product 2, P3= chili product 3. Bulb heat-based dryers can work well according to their use. This tool produces an average temperature of 52.44°C, and the highest temperature reaches 60°C. The capacity of this bulb heat-based dryer has 6 shelves and can accommodate 4,800 g of chili, with each shelf able to accommodate 800 g of chili.. Based on tests on the parameters that have been carried out, the average water content in chilies is 57.3354%. This result is still very high compared to the SNI for the water content in dried chilies of 11%.

Abstract

Artikel ini mengkaji tentang deforestasi taman hutan raya (TAHURA) Abdul Latif di Sinjai dalam perspektif hukum Islam. Artikel ini berkontribusi dalam diskusi mengenai hutan yang mengalami deforestasi akibat pengelolaan hutan yang tidak mengedepankan konservasi. Pertanyaan utama dalam penelitian ini adalah bagaimana kerusakan hutan atas pembangunan bumi perkemahan TAHURA dalam perspektif hukum Islam? Untuk menjawab pertanyaan tersebut, penelitian ini menggunakan studi kualitatif melalui observasi dan wawancara. Penelitian ini juga menggunakan data netnografi yang sumber data diperoleh melalui penelusuran data online dan observasi partisipan online. Hasil penelitian ini menunjukkan bahwa, kerusakan hutan atas pembangunan perkemahan TAHURA Abdul Latief Kabupaten Sinjai masih tergolong kecil jika dibandingkan secara kuantitatif 1,2 Ha tambah akses jalan sekitar 400 meter, dengan jumlah luas TAHURA sekitar 720 Ha hanya sekitar 0,3% luas area. Selain itu, kerusakan atas pembangunan bumi perkemahan dan track sepeda di TAHURA Abd. Latief pada dasarnya mendatangkan manfaat atas peserta perkemahan dan manfaat bagi masyarakat (penjual kelontongan) jika ada kegiatan perkemahan. Namun, manfaat tersebut terbilang kecil jika dibandingkan dengan kerusakan hutan akibat pembukaan lahan, dikarenakan bukan sesuatu yang urgen untuk dilakukan

Abstract

Educational Forests are greatly needed by higher education institutions, especially those studying forestry. Various activities can be carried out by students, lecturers, and related parties to be involved in research in order to develop science and knowledge so that they can make real contributions, and empower communities around forest areas to be competitive so that they do not have a high enough value for forest resources, especially wood forest products. In addition, the existence of educational forests is considered capable of mitigating climate change at a micro level. The research was conducted in the Tadulako University Educational Forest as shown in the picture above. The stages of this research consist of two, namely a ground check by taking random samples of trees. Then the second is to identify local community wisdom using qualitative methods with the Rapid Rural Appraisal approach. This research was conducted in the Tadulako University Educational Forest with a direct observation approach. The results of this study found that the land in the forest is still maintained by implementing a forestry system in the form of, where the community utilizes the forest by taking non-timber forest products, rattan, and air ecosystem services.

Abstract

Micro, Small, and Medium Enterprises are one of the important pillars in a country's economy. Despite their strategic role, MSMEs often face a number of challenges, such as intensifying competition, changing consumer tastes, evolving technology, and access to a wider market. This study aims to analyse product and service innovation strategies to expand the MSME market. This research employs a qualitative research approach, more precisely, a literature review, where data will be examined and explained by drawing upon information and textual materials collected from a variety of sources. The study results show that innovation in products and services plays a key role in the growth and sustainability of micro, small and medium enterprises. MSMEs play a vital role in the economy by creating jobs and contributing to sustainable economic growth. Innovation differentiates MSMEs from their competitors in an increasingly globalised and dynamic business environment. Innovative products and services can attract customer attention, provide a competitive advantage, improve product quality, and build long-term relationships with customers.

Abstract

Oil palm empty fruit bunch (OPEFB) is a common solid waste from palm oil industry that requires proper handling to be processed into bio-ethanol as new bio-energy source to substitute fossil fuel, oil, gas, and coal. Microbial applications have been considered an effective way to degrade a lignocellulosic biomass into simple sugars as a critical material for bio-ethanol production. It efficacy to degrade cellulose was determined by cellulase production from CMC as medium. Actinomycetes isolate 11.2.A showed high cellulase activity on carboxylmethyl cellulose (CMC) broth. After incubation for 5 days at 30oC, pH 7 and 150 rpm agitation rate the highest cellulase activity generated by the isolate 11.2.A was 0.62 U/ml on CMC as medium. Actinomycetes isolates 11.2.A was proved to be the effective producer of cellulase specific for CMC. The isolate 11.2.A was also selected to be used in liquefaction of OPEFB. Actinomycetes isolate 11.2.A gave a better performance for being able to degrade the OPEFB with cellulase activity at 0.42 U/ml. This microbial and its enzymes should be very useful in the process of turning the solid waste like OPEFB into value products such as reducing sugar, sugar alcohol and bio-ethanol.
