2024-10-25T09:41:22+00:00

Laboratory mice are widely used in biomedical research due to their genetic similarities to humans. The dietary needs of mice in Indonesia. However, they are frequently not satisfied by commercially available feed. This indicates the necessity for locally obtained, customized feed formulations, like those that include mung beans, which are high in vital nutrients and promote sustainable agriculture. This study aims to compare the effect of various mung bean-based feeds on the weight gain of female mice and their feed conversion value. Four feed formulations with varying concentrations of mung beans (85%, 75%, 65%, and 55%) were compared to commercial Broiler II feed, using 20 female mice over two months. The study involved daily feeding, weighing consumed feed, and mice’s body weight to determine the Feed Conversion Ratio (FCR), and the Kruskal-Wallis test for statistical analysis. The results show no statistical difference between treatments, which means all treatments are comparable to the control groups in promoting mice growth in all the parameters observed. Nevertheless, a certain trend was observed where the higher the mung bean content, the more similar the results to the control group. Thus, treatments MB85 containing 85% mung beans might have the greatest potential to promote mice growth.

2024-10-14T11:17:34+00:00

Indonesia is home to 449 of the 7,757 Anura species that exist worldwide. An important component of the ecosystem, amphibians play a crucial role in maintaining environmental stability. Amphibians are quite vulnerable to changes in their environmental quality. The Durian Luncuk II Nature Reserve is an amphibian habitat in Batanghari Regency, Jambi Province. Covering 41.37 hectares of forest, this nature reserve was designated by the Minister of Forestry in 1997. Its lowland habitat and vegetation structure create an ideal environment for various amphibian species. This study aims to identify the amphibian species in the Duruan Luncuk II Nature Reserve and to determine the biological index. The research employs the Visual Encounter Survey (VES) method combined with the Line Transect system. The biological indices analyzed include the Diversity Index, Evenness Index, and species Richness Index. Data collection identified 11 amphibian species across four families. The Diversity Index was classified as moderate (2.1), while the Evenness Index indicated an almost uniform distribution (0.9). The species Richness Index was classified as low (2.8). Not all regions of CA Durian Luncuk II have been surveyed for this study. Therefore, a comprehensive survey in habitats that support amphibian encounters is still needed.

Potensi Pengembangan Koridor Siamang (Symphalangus syndactylus) Melalui Pendekatan Lansekap Ekologi dan Kearifan Lokal Lubuk Larangan di Perkebunan Kelapa Sawit

2025-03-05T10:18:36+00:00

One of the key strategies for developing habitat corridors for the Siamang (Symphalangus syndactylus) is by connecting conservation forest plots within oil palm plantation concessions to forested areas outside the concession boundaries. This approach allows Siamangs to access larger movement areas, increasing their chances of long-term survival. This study was conducted at PT. Kencana Sawit Indonesia (PT. KSI), located in Solok Selatan District, has allocated 1,800 hectares as conservation areas within its concession. Since 2014, PT KSI, in collaboration with the Natural Resources Conservation Agency (BKSDA) and Kalaweit Indonesia Foundation, has implemented a Siamang reintroduction program in 800 hectares of its conservation area, with 18 individuals released and six recorded births. This study employed a vegetation analysis to assess the habitat's carrying capacity along river buffer zones, and Focus Group Discussions (FGDs) to explore the distribution and cultural values of lubuk larangan (community-protected sacred river pools). A landscape conservation approach has been initiated by utilizing four river buffer zones as potential corridors connecting forest plots within the concession, and possibly linking them to forest areas within the Kerinci Seblat National Park (TNGKS). Results indicate a high vegetation Diversity Index within the concession and a Moderate Index for the outside. The Lubuk Larangan approach highlights the role of local communities in protecting riparian forests, contributing to ecosystem and fish resource conservation. This landscape model has strong potential to be adopted in corridor development initiatives beyond the concession area, ensuring sustainable habitat connectivity between PT. KSI’s conservation zones and TNGKS.

Optimasi Proses Biodrying: Penggunaan Formulasi Konsorsium Mikroorganisme dalam Bahan Pembawa

2025-03-07T02:53:40+00:00

Household organic waste generated daily holds potential for conversion into bioenergy through biodrying technology. Biodrying is a biological drying process that relies on microbial activity to reduce the moisture content in organic waste, producing solid fuel. This study aimed to formulate a microbial consortium for biodrying applications and to compare the effectiveness of solid (talc-based) and liquid (molasses-based) carriers on biodrying performance and inoculant stability. The consortium comprised Lysinibacillus halotolerans, Bacillus soronensis, Lactobacillus rhamnosus, Pichia manshurica, and phosphate-solubilizing bacteria. Isolate rejuvenation was performed using selective culturing followed by characterization. Microbial formulations were developed in both solid and liquid forms and applied to organic waste. Key parameters observed included moisture content, temperature, pH, and inoculant viability over a three-month storage period. The results showed that both talc and molasses carriers were more effective than commercial controls, as indicated by higher temperatures (44.1°C and 43.66°C), lower moisture content (44.5% and 45.25%), and favorable pH values (5.8 and 6.35), which supported mesophilic and thermophilic microbial activity during the biodrying process. Peak microbial activity occurred on day four, predominantly driven by Bacillus species during the thermophilic phase. Inoculant stability was also higher in the talc-based formulation, potentially due to its magnesium and silicon content, which contributed to maintaining microbial viability during storage.
