Abstract

This study aims to evaluate the nutritional balance of adult female dairy cows at UPTD Puskeswan PadangPanjang. The livestock used in this study were all adult female dairy cows (who had given birth) from the FriesHolland breed that were kept in the breeding cage of UPTD Puskeswan Padang Panjang City with physiologicalstatus, namely 1 pregnant lactation, 5 non-pregnant cows and dry pregnant cages as much as 2 tails. The variablesmeasured in this study were the consumption of dry matter (DM) feed, consumption of TDN, consumption of crudeprotein (CP) and consumption of calcium (Ca). The data obtained every day were then tabulated based on the range ofconsumption of DM, the range of TDN consumption, the range of CP consumption and the range of Ca consumptionfor dairy cows / head / day and then compared with the standards from the National Research Council (NRC) 1978table. The analysis was carried out descriptively. Descriptive analysis was used to explain nutrient balance. From theresults of the study it can be concluded: 1) dry matter consumption of all lactating cows and dry cows in pregnantcows is higher than the need, 2) consumption of TDN and calcium for lactating cows with milk production below 5 kg /head / day and dry cows with pregnant cows with body weight 400 kg is higher than the need, while the consumptionof TDN and calcium from lactating cows with milk production above 5 kg / head / day and pregnant cows with a bodyweight of 500 kg is lower than the need and 3) consumption of crude protein (CP) of all lactating cows and pregnantpen dry cows with a body weight of 500 kg lower than the need, however the consumption of CP for pregnant cowswith a body weight of 400 kg is higher than the need. In order to increase the productivity of the dairy cows that arekept, it is recommended that the managers of the UPTD Puskeswan Padang Panjang City improve the balance offorage and concentrate. To achieve a balance of 60% forage: 40% concentrate, fresh forage was given as much as30.78 kg / head / day and concentrate was given as much as 20.52 kg / head / day.

Abstract

Endophytic fungi originating from mangroves are potential sources of secondary metabolites with varying bioactivities. This research explores the bioactive metabolites produced by endophytes derived from mangrove plants. Endophytic fungi were collected from various parts of several mangrove plants (roots, stems, and leaves, as well as the surrounding mud). A total of 17 endophytics fungi were obtained. The isolates were derived from the leaves (1 isolate), stems (8 isolates), roots (5 isolates), and surrounding mud (3 isolates). A single fungal colony was cultured using solid-state fermentation for 14 days. The fermented fungal biomass was extracted using ethyl acetate (EtOAc) and evaluated for its antibacterial activity against clinical pathogenic bacteria. In the preliminary screening, the EtOAc extract of the CB07RF1 isolate exhibited notable growth-inhibitory effects against Pseudomonas aeruginosa. The isolate was verified by molecular identification using a study of the rDNA internal transcribed spacer (ITS) sequence, revealed that isolate CB07RF1 was very similar to Fusarium equiseti (99% similarity). Isolate 20CB07RF1, obtained by solid-state fermentation using a rice medium indicated as peptide compound group, and featured active components that exhibited potent growth inhibitory activity against Pseudomonas aeruginosa at a concentration of 12.5 mg/mL. This study demonstrates, for the first time, that Fusarium equiseti extracts grown in a rice medium contain antimicrobial compounds that can inhibit the growth of P. aeruginosa, an important clinical pathogen known for its antibacterial resistance. These findings accent mangrove endophytic fungi as important sources of bioactive compounds and will advance related research in the fields of biotechnology, pharmacology, and life sciences.

Abstract

Fucoxanthin is an anticancer, antioxidant, antimicrobial, and anti-inflammatory bioactive compound. Unfortunately, the conjugated double bonds of the fucoxanthin structure make it unstable, posing issues for product development, particularly with regard to shelf life. This research study aims to synthesize nano chitosan–pectin and encapsulate isolated fucoxanthin by nano chitosan–pectin using an ionic gelation method. Fucoxanthin was obtained through isolation of microalgae species Cyclotella striata. The best result of nanoparticle size using a particle size analyzer was chitosan:pectin 1 : 2 of 172 nm. Fourier transform infrared analysis showed that there was an interaction between chitosan–pectin and fucoxanthin, which was characterized by a shift in the C O absorption fucoxanthin from 1736 to 1632 cm-1. The result of morphological analysis of nano chitosan–pectin–fucoxanthin using a scanning electron microscopeshows a spherical morphology with a size between 140 and 265 nm. The result of encapsulation efficiency was 75.18%, whereas encapsulation stability increased fucoxanthin oxidation half-life 4.7 times longer than that of unencapsulated fucoxanthin. The nano chitosan pectin could be utilized as a matrix conjugate to increase the stability of fucoxanthin significantly by encapsulation. This information is expected to be useful in developing encapsulation applications for unstable compounds.

Abstract

This study aimed to assess glucosamine production through enzymatic activity, utilizing actinomycetes sourced from shrimp shell waste (SSW) in a solid-state fermentation (SSF) process. A total of 16 actinomycetes underwent chitinase activity screening, and the strain exhibiting the highest chitinolytic index was chosen for subsequent morphological and phylogenetic analyses. High Performance Liquid Chromatography (HPLC) was employed to analyze glucosamine produced from the bioconversion of SSW via SSF. Optimal conditions for glucosamine production were determined by varying time, pH, and temperature. Isolate 18D36-A2 showed the highest chitinolytic index of 1.02 in the 32-mm clean zone. Phylogenetic analysis revealed 97% similarity to the genus Micrococcus, identifying it as a novel Micrococcus unila strain 18D36-A2 and deposited in GenBank. This isolate effectively converted shrimp shells. The findings showcase the bioconversion of SSW to glucosamine through SSF using the Micrococcus unila 18D36-A2. Furthermore, this study establishes a foundation for future research on environmentally friendly and sustainable designs for glucosamine production.

Abstract

Hutan Kemasyarakatan (HKm) termasuk hutan negara. Pemanfaatannya adalah untuk pemberdayaan masyarakat sekitar hutan. Untuk itu dalam pengelolaannya masyarakat harus dilibatkan agar tujuan dari pemberdayaan itu dapat tercapai. Peningkatan pendapatan menjadi tolak ukur untuk melihat kesejahteraan masyarakat, diantaranya adalah dengan pemberian stup (kotak) lebah Trigona (Apis trigona). Pemberian stup lebah ini bertujuan untuk membantu petani lebah di Hutan Kemasyarakatan Kecamatan Pagar Dewa Lampung Barat guna menambah pendapatannya. Hal itu disebabkan karena kurangnya stup lebah yang tersedia serta kurangnya sumber pakan menjadi hambatan dalam meningkatkan hasil panen madu oleh petani. Disini, artikel ini memberikan gambaran dan penjelasan tentang pelaksanaan program kerja Hutan Kemasyarakatan melalui pemberian stup lebah Trigona kepada Kelompok Tani Hutan (KTH) Wonorejo di Pekon Basungan, Lampung Barat. Pemberian stup lebah dilaksanakan menggunakan pendekatan kualitatif dimana modelnya adalah model naratif. Hasilnya, Kelompok Tani Hutan Wonorejo mendapatkan tambahan stup lebah dan tambahan sumber pakan untuk meningkatkan hasil panen madu. Artikel ini lebih lanjut diharapkan dapat menambah wawasan dalam bidang pertanian dan kehutanan khususnya petani untuk mengembangkan hasil hutan bukan kayu berupa pembudidayaan lebah madu. Kata Kunci: Hutan Kemasyarakatan, Peningkatan Pendapatan, Lebah Trigona, Hasil Hutan Bukan Kayu  Community Forests (Hutan Kemasyarakatan/HKm) are state forests. The use is for empowering communities around the forest. For this reason, in its management, the community must be involved so that the goals of empowerment can be achieved. Increasing income is a benchmark for assessing community welfare, including providing trigona bee stup. The aim of providing bee stup is to help bee farmers in the Pagar Dewa District Community Forest, West Lampung, to increase their income. This is because farmers are unable to increase their honey output due to a shortage of feed sources and bee stup. Here, this article provides an overview and explanation of the implementation of the Community Forest work program by providing Trigona bee stup to the Wonorejo Forest Farmers Group (Kelompok Tani Hutan/KTH) in Pekon Basungan, West Lampung. The provision of bee stup is carried out using a qualitative approach where the model is a narrative model. As a result, the Wonorejo Forest Farmers Group received additional bee stup and additional food sources to increase honey yields. It is intended that this essay will deepen readers' understanding of the domains of forestry and agriculture, particularly helping farmers create forest-based products that are not timber by raising honey bees.

Abstract

The majority of people in Pisang Indah Village, Bumi Agung District, Way Kanan Regency, Lampung Province, are farmers. In farming, they use chemical fertilizers. Unfortunately, continuous use of chemical fertilizers can result in decreased soil quality and damage to soil structure. In order to replace chemical fertilizers with more affordable and ecologically friendly alternatives, socialization is being carried out on the manufacturing of Liquid Organic Fertilizer (Pupuk Organik Cair/POC) based on Local Microorganisms (Mikroorganisme Lokal/MOL). POC which comes from the fermentation of natural organic materials has become the main focus in efforts to increase plant productivity in a sustainable manner. This activity uses a descriptive-explanatory qualitative approach so that it presents practical steps to produce environmentally friendly and effective POC based on banana stems and rice washing water as an alternative fertilizer. The focus on the use of local organic materials, such as banana stems and rice washing water, is driving the adoption of sustainable agricultural practices in various agricultural communities. Through outreach activities and practical training, this article highlights farmers' interest and enthusiasm for POC as an alternative fertilizer that has the potential to provide good crop yields without damaging the environment. With the use of POC, it is hoped that in the future it can become the basis for efforts to empower farming communities in sustainable natural resource management to strengthen sustainable food security.
