Abstract

Mangifera foetida, commonly referred to as bacang, is a tropical fruit tree of the Anacardiaceae family widely used in traditional medicine throughout Southeast Asia for a variety of therapeutic purposes. Recent scientific studies have validated many of these ethnomedicinal uses by uncovering a diverse phytochemical composition alongside notable pharmacological activities. This review synthesizes current knowledge on the nutritional content, bioactive compounds, and pharmacological effects of M. foetida, with particular focus on its antioxidant, antimicrobial, cytotoxic, antidiabetic, and anti-inflammatory properties. Key secondary metabolites, including mangiferin, phenolic compounds, flavonoids, and essential oils, are believed to underpin its therapeutic efficacy. Moreover, the fruit and other plant parts provide considerable nutritional benefits, supplying essential vitamins, minerals, and dietary fiber. Despite these promising findings, further investigations are needed to clarify underlying mechanisms, improve extraction techniques, and evaluate clinical effectiveness. This review seeks to establish a comprehensive reference to support future research and facilitate the development of M. foetida-derived nutraceuticals and pharmaceuticals.

Abstract

Kampung Mamolo, located in South Nunukan District, North Kalimantan, is one of the key centers for seaweed cultivation in the Indonesia–Malaysia border region. This study aims to explore the seaweed species cultivated by the local community and to examine their morphological characteristics and economic value. A qualitative descriptive method was used, involving field observations, interviews with seaweed farmers, and literature review. The findings identified nine seaweed species from three major divisions: Chlorophyta, Phaeophyta, and Rhodophyta. Among these, three species—Eucheuma cottonii, Eucheuma spinosum, and Kappaphycus alvarezii—are actively cultivated due to their high economic value as sources of carrageenan widely used in food, pharmaceutical, and cosmetic industries. Cultivation is carried out traditionally using the floating-line system, which has proven effective in supporting sustainable production. This research contributes to the documentation of local marine biodiversity and its potential to enhance coastal community livelihoods.

Abstract

This high level of organic waste poses significant environmental risks if left unmanaged. Therefore, there is a need for waste management strategies that are simple, cost-effective, and environmentally sustainable. One such approach is vermiculture the cultivation of earthworms to convert organic waste into nutrient-rich vermicompost. Integrating Effective Microorganisms (EM4) and tomato waste into cattle manure feed has the potential to enhance nutrient bioavailability through microbial fermentation, which in turn supports earthworm metabolism and growth. This study aims to evaluate the productivity of Lumbricus rubellus and the efficiency of vermicompost production under different feed formulations. The experiment was conducted using a completely randomized design (CRD) with four feed treatments: cow manure (P1), cow manure + EM4 (P2), cow manure + tomato waste (P3), and cow manure + tomato waste + EM4 (P4), with three replications per treatment. The observed parameters included earthworm weight, earthworm length, vermicompost production, and proximate analysis of earthworm biomass. This study also assesses the impact of these feed combinations on the growth performance of L. rubellus and the resulting vermicompost yield, within the agroclimatic conditions of Pangalengan. Additionally, the nutritional composition of the harvested earthworm biomass is evaluated to explore its potential as a supplementary protein source for livestock feed contributing to sustainable and circular agricultural practices in dairy farming systems.

Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) remains a major driver of antimicrobial resistance and necessitates precise non-antibiotic therapeutics. This review comprehensively evaluates evidence on bacteriophage therapy against resistant S. aureus and the molecular and structural barriers that limit efficacy. A structured search of PubMed, Scopus, Google Scholar, ScienceDirect, KAKEN, and ResearchGate identified peer-reviewed studies published up to 2025 using predefined keywords. Articles were screened and synthesized thematically across vitro assays, Ex Vivo burn-wound models, and host-range/biofilm studies, with mechanistic mapping of mecA/PBP2a and O-acetyltransferase A (OatA), and appraisal of dosing strategies (single, repeated, prophylactic). Findings show consistent phage-mediated reductions of S. aureus in vitro; in Ex Vivo human/porcine skin, higher doses and repeated application enhanced suppression, and prophylaxis prevented colonization. Activity against biofilm was strain- and phage-specific; some phages reduced biomass while others paradoxically increased it, and narrow host range plus OatA-linked barriers persisted. In conclusion, bacteriophages are promising but require precise strain matching and micro-environmental consideration. The research highlights the importance of biofilm-aware screening, strategic formulation of phage cocktails or lytic enzymes, optimized dosing regimens for repeated or prophylactic use, and the integration of molecular characterization with synthetic phage engineering to broaden host range and accelerate translation into clinical applications.

Abstract

AbstrakAnak berkebutuhan khusus (ABK) sering kali menghadapi hambatan dalam mengembangkan keterampilan bantu diri (self-help skills) dan keterampilan hidup (life skills) yang penting bagi kemandirian dan integrasi sosial mereka. Oleh karena itu, kegiatan pengabdian masyarakat ini dilakukan untuk meningkatkan pemahaman dan kapasitas orang tua dalam melatih kedua keterampilan tersebut pada anak mereka. Kegiatan ini dilakukan melalui seminar parenting, diskusi kelompok, dan penyebaran kuesioner kepada para orang tua ABK. Hasil kegiatan menunjukkan bahwa sebagian besar orang tua telah menyadari pentingnya keterampilan bantu diri sebagai fondasi utama, dan memahami bahwa keterampilan hidup merupakan kelanjutan dari kemampuan dasar yang harus dilatih secara konsisten. Diskusi kelompok juga memperlihatkan praktik-praktik efektif yang digunakan orang tua, seperti pelabelan barang, penggunaan alat bantu visual, dan manajemen perilaku. Kegiatan ini berhasil menciptakan ruang berbagi antar orang tua serta meningkatkan kesadaran akan pentingnya peran keluarga dalam membentuk kemandirian anak ABK. Hasil ini menegaskan perlunya penguatan dukungan berkelanjutan melalui pelatihan lanjutan dan kolaborasi lintas profesi guna memperluas dampak jangka panjang kegiatan serupa. Kata kunci: anak berkebutuhan khusus; keterampilan bantu diri; keterampilan hidup; kemandirian; peran orang tua. AbstractThis community service activity aims to increase parental awareness and competence in teaching self-help skills and life skills to children with special needs. These skills are essential for children with special needs to gain independence and interact with their environment. The method used in this program includes seminars and questionnaires distributed to parents. The data collected from the questionnaires and seminar notes were analyzed qualitatively. The results show that parents understand the importance of self-help skills—such as eating, bathing, and dressing—as the foundation for more complex life skills, including social interaction, communication, and understanding social norms. Several parents shared practical strategies and aspirations regarding their children's future abilities. Through this activity, parents also gained insight into how consistent training and motivation play a key role in developing these skills. The outcomes of the community service indicate a positive change in parents’ perspectives and readiness to support their children. This program demonstrates the importance of providing structured and sustainable support for families with children with special needs. Keywords: children with special needs; independence; life skills; parental role; self-help skills.

Abstract

The utilization of cow manure can reduce environmental pollution around livestock farms. One way to utilize cow manure is by turning it into solid organic fertilizer. The quality of solid organic fertilizer is determined by various factors, including the raw materials, fermentation methods, and composting time. The aim of this study is to improve the quality of solid organic fertilizer using a decomposer. The production of solid organic fertilizer in this study was carried out in two ways: first, by turning the cow manure every 10 days for 40 days (A), and second, using a decomposer with ratio of 1 Liter/3 tons to the cow manure and then turning it every 10 days for 40 days (B). The results showed an increase in C-organic content by 9.56%, nitrogen by 42.02% , phosphate by 19.00% and potassium by 6.56%. This indicates that the addition of a decomposer in the composting process can improve the quality of solid organic fertilizer.

Abstract

Differences in organic matter content and soil pH can cause different fungal spore growth. Soil type is one of the factors that directly affect the presence of fungi. This research was conducted on the Wallace and Weber lines in Ternate, North Maluku. The research location was chosen because it has endemic fungal species, biodiversity that has not been widely discovered, and unique geographical conditions. Data collection was carried out through direct surveys using exploration methods, sampling with purposive random sampling, and direct collection of fungi based on shape, color, stem length, diameter, and type of substrate where they grow (soil, wood, leaves, and others), along with observations of fungal morphology. Qualitative analysis includes determining the order, family, genus, and scientific name presented in the form of tables and images, as well as descriptions of the characteristics of each species based on the identification results. The diversity index was also calculated. Environmental parameters measured included air temperature, soil moisture, light intensity, and soil pH. The results of the study showed that there were 20 species of fungi in the Moya Mabuku Hiking Trail Forest Area, Central Ternate District, Ternate City, North Maluku, Indonesia, with GPS coordinates of 0.8° North Latitude and 127.3630910° East Longitude. These fungi belong to the Ascomycota and Basidiomycota divisions, with the families Helotiaceae, Strophariaceae, Hygrophoraceae, Auriculariaceae, Omphalotaceae, Tremellaceae, Hypoxylaceae, Phyllotopsidaceae, Polyporaceae, Gardonemataceae, Tricholomataceae, Sarcoscyphaceae, Agaricaceae, Mycenaceae, Psathyrellaceae, and Cortinariaceae. The results of environmental parameter measurements on wood, soil, and coconut shell substrates showed that soil pH ranged from 3.85-6.10; air humidity 77.5-91.5% RH; substrate humidity 36.5-99.9%; Light intensity ranges from 93.5 to 7496 cd; air temperature ranges from 27.7 to 33.9°C; and substrate temperature ranges from 27.4 to 33.9°C. These pH conditions, ranging from 3.85 to 6.15, are considered optimal for supporting the growth of macroscopic fungi.
