Abstract

Screening and Identification of Ligninolytic Microbes in the Natural Decomposition of Oil Palm Empty Fruit Bunch  ABSTRACTOPEFB (oil palm empty fruit bunch)could potentially be utilized as organic fertilizer or animal feed through composting. Information on microorganisms that play important roles in the natural decomposition of OPEFB is to date not much known yet. This research was aimed to obtain and, subsequently, to molecularly identify lignin-degrading microbial isolates responsible for naturally decomposing OPEFB in the Oil Plant Plantation and Palm Oil Refinery Plant, PTPN VIII Cikasungka, Bogor. Screening for active lignin-degrading isolates was carried out on 17 naturally decomposing OPEFB samples. A total of 19 isolates of fungi and 80 isolates of bacteria were obtained. Ligninolytic activity was measured by Sundman and Nase testing methods. Ligninolytic activity was found on 13 fungal isolates and 15 bacterial isolates. The active isolates were subsequently identified molecularly based on ITS sequence in the ribosome DNA area for fungi and in 16S rRNA genes for bacteria. The results showed that the lignin-degrading microorganisms obtained consisted of 5 bacterial isolates from the genus Bacillus and 3 fungal isolates from the genus Rhizopus and Aspergillus. Keywords: composting, lignin, microbes, OPEFB, 16S rRNA ABSTRAKTKKS (tandan kosong kelapa sawit) berpotensi dimanfaatkan sebagai pupuk organik atau pakan ternak dengan cara pengomposan.

Abstract

The Museum of Perjuangan Subkoss Garuda Sriwijaya is a museum that preserves the history of South Sumatra’s struglle against the Dutch and Japanese colonialists. This research aims to obtain the results of an ethnomathematics study from the Museum of Perjuangan Subkoss Garuda Sriwijaya regarding historical, philosophical, and mathematical aspects and implement it in the Merdeka Curriculum in mathematics for elementary schools. This research employs an ethnographic approach with a qualitative descriptive approach, utilizing observation, interviews, documentation, field notes, and data triangulation. The analysis techniques include data reduction, data presentation, verification, and conclusions drawings. The study involved three informants who had direct interaction with the Museum of Perjuangan Subkoss Garuda Sriwijaya. The results of this research shows that ethnomathematics studies offer several insights: the historical aspect introduces local history and culture through artifacts that supported the struggle during the physical revolution; the philosophical aspectteaches the values ​​of caring, cooperation, creativity, and diversity within society; and the mathematical concepts reveals the concept of geometry, including area, perimeter, volume of both two-dimensional figures and three-dimensional figures, and length measurement.

Abstract

Pembangunan berkelanjutan bertujuan untuk meningkatkan kesejahteraan masyarakat dengan mempertimbangkan aspek ekonomi, sosial, dan lingkungan. Dalam rangka mendukung pencapaian tersebut, pemerintah menginisiasi penguatan peran Badan Usaha Milik Desa (BUMDes) sebagai strategi dalam mengembangkan ekonomi berbasis potensi lokal. Desa Ngoran, Kecamatan Nglegok, Kabupaten Blitar, memiliki sumber daya manggis yang belum dioptimalkan pemanfaatannya dengan nilai jual yang relatif rendah. Pengabdian ini bertujuan untuk meningkatkan nilai tambah komoditas manggis melalui inovasi produk berupa sirup manggis. Upaya ini dilakukan dengan mengadakan pelatihan pengolahan sirup sari buah bagi masyarakat setempat. Dalam implementasinya, BUMDes Karya Mandiri berperan sebagai mitra utama dalam proses produksi dan distribusi produk. Berdasarkan hasil pengabdian bahwa formulasi optimal sirup manggis terdiri dari rasio 1:1:2 (air, sari buah manggis, dan ekstrak manggis), dengan tambahan gula sebanyak 50%. Selain itu, sirup manggis ini memiliki aktivitas antioksidan dengan nilai IC50 sebesar 352,95 ppm. Program pengembangan sirup manggis berbasis pemberdayaan masyarakat ini berkontribusi pada peningkatan nilai ekonomi serta kesejahteraan desa. Untuk menjamin keberlanjutan program, diperlukan penguatan rantai pasok, peningkatan efisiensi teknologi produksi, serta penerapan strategi pemasaran yang lebih luas guna memperluas jangkauan pasar.

Abstract

Roads must have safety and comfort, which can be seen through the condition of the pavement. A good pavement is influenced by a good bearing capacity of the subgrade. Not infrequently, road damage that occurs is caused by a lack of bearing capacity of the subgrade (CBR<6). One way to improve the bearing capacity of the subgrade is to stabilize it with polyacrylamide (PAM) synthetic polymer. Subgrade stabilization was carried out on local soil at Jalan Cisasawi, Desa Cihanjuang with a percentage of 4%, 6%, 8%, 10%, and 12% of the dry soil weight. From the results of laboratory CBR testing, calculations were made to determine the effect on the thickness of flexible pavement using the SKBI 1987 method. After the calculation, it can be concluded that the CBR value affects the thickness of the flexible pavement layer. The greater the subgrade CBR value, the thinner the pavement thickness (with 8% polyacrylamide). This has been proven in the calculation where PAM managed to increase the bearing capacity of the soil to the maximum at 8% PAM content (soaked CBR 16.4% and unsoaked CBR 20.5%) and the thickness of the lower foundation layer is 25 cm (the thinnest among other levels).

Abstract

Efforts are needed to accelerate the decomposition of peat fiber to reduce the fiber content through bioaugmentation using Pseudomonas taiwanensis bacteria so that it can reduce the high-water content of peat fiber. The research aimed to determine the effect of adding Pseudomonas taiwanensis bacteria on the decomposition of peat fiber. This research is a laboratory experimental research. The research sampling location was in Bereng Bengkel Village, Palangkaraya. The parameters observed included fiber content, fiber size distribution, and peat fiber decomposition speed following the Peat Testing Manual. The research instrument was an observation sheet for fiber content, size distribution, and peat fiber decomposition speed. Research data was analyzed using descriptive statistical analysis. The results showed that adding 15% Pseudomonas taiwanensis bacteria with a curing period of 28 days in fibrous peat resulted in the highest reduction in fiber content, from the initial condition of 61.14% to 12.33%. This variation also shows a decrease in coarse and medium fiber content and a significant increase in fine fiber content. The decomposition rate for this variation shows good consistency. The conclusion was that adding 15% Pseudomonas taiwanensis bacteria with a curing period of 28 days showed optimal results in accelerating the decomposition of peat fiber through the bioaugmentation method.
