PELATIHAN MANAJEMEN KESEHATAN DAN KESELAMATAN KERJA (K3) DI PUSKESMAS OESAPA
Full text linkCommunity Health Centers are the front guard in providing health services to the community, where the government has designated them as First Level Health Facilities (Level 1 Health Facilities) which are the reference for obtaining health insurance at the next level (Hospital). Therefore, community health centers must provide the best services and complete education, so that the goals of public health can be achieved. Occupational Health and Safety is an important element in protecting ourselves both from the service provider side (employees/staff) and from the service recipient side (patients/community). Occupational Health and Safety itself consists of several elements that must be understood, including: Occupational Diseases, Personal Protective Equipment, Psychology and Ergonomics, Comfort (Noise and Vibration), Dangers (Mechanical and Electrical) and ultimately can be intertwined in the Safety Management System and Occupational Health. All of these things have not been fully realized and applied in everyday life, even in health facilities. With this activity, it is hoped that the implementation of good Occupational Health and Safety will automatically increase the health figures of the community itself.
Evaluasi dan Retrofitting Seismik Bangunan Asrama Menggunakan Steel Panel Damper: Studi Kasus Gedung Jieshou, Taiwan
Full text linkBangunan asrama yang terletak di area rumah sakit dan dibangun sebelum diberlakukannya standar desain gempa modern di Taiwan umumnya memiliki kapasitas seismik rendah dan rentan terhadap kerusakan saat terjadi gempa besar. Penelitian ini mengevaluasi performa seismik Gedung Jieshou, sebuah bangunan asrama di kawasan Tri-Service General Hospital, serta merancang strategi retrofit menggunakan Steel Panel Damper (SPD) untuk meningkatkan kapasitas strukturnya. Pemodelan dan analisis dilakukan dengan perangkat lunak ETABS menggunakan pushover analysis nonlinier berbasis metode TEASPA, yang memungkinkan konversi kurva kapasitas menjadi spektrum kapasitas untuk menentukan titik performa dalam bentuk percepatan puncak tanah (PGA). Hasil analisis menunjukkan bahwa kapasitas eksisting belum memenuhi standar CPAMI, dengan rasio gaya geser terhadap berat bangunan (V/W) sebesar 0,234 dan Ap=0,201g pada arah X. Setelah penerapan SPD berkapasitas 75 ton pada 8 titik sampai dengan lantai 7 bangunan, performa meningkat menjadi Ap=0,274g dengan rasio V/W sebesar 0,292. Evaluasi sendi plastis menunjukkan bahwa SPD efektif menyerap energi gempa. Studi ini menyimpulkan bahwa penggunaan SPD secara signifikan meningkatkan kapasitas lateral dan performa seismik tanpa mengganggu fungsi utama bangunan ketika diimplementasikan. Kata kunci: steel panel damper, analisis pushover, kapasitas gempa, performa struktur, retrofittin
Analisis Pengaruh Perbandingan ΔT terhadap Optimasi Energi dengan Metode Problem Table
Full text linkProblem table analysis adalah metode kuantitatif dalam teknologi pinch untuk menghitung kebutuhan minimum panas (hot utility) dan pendinginan (cold utility) pada sistem termal industri. Dengan menyusun data suhu dan entalpi dalam bentuk tabel, metode ini membagi fluida ke dalam interval suhu berdasarkan ΔTmin, lalu menghitung surplus atau defisit energi di setiap interval melalui neraca entalpi. Hasil divisualisasikan sebagai heat cascade untuk menentukan titik pinch dan batas pemanfaatan panas internal. Analisis pada ΔTmin 10–28°C menunjukkan bahwa semakin besar ΔTmin, semakin besar kebutuhan hot utility, sementara cold utility mengalami fluktuasi akibat variasi distribusi panas, karakteristik stream dan konfigurasi aliran. Pemilihan ΔTmin yang tepat penting untuk menyeimbangkan efisiensi energi internal dengan konsumsi energi eksternal, guna mencapai desain jaringan penukar panas yang optimal, efisien dan ekonomis. Kata kunci: problem table, optimasi, suh
Review: Modern Extraction Methods for Extraction Proanthocyanidins from Natural Products
Full text linkProanthocyanidins are widely distributed in many plant species and are recognized for their beneficial health effects, particularly their antioxidant and anti-inflammatory activities. This literature review aims to evaluate modern extraction techniques used to isolate proanthocyanidins from natural sources. Conventional methods, such as maceration and Soxhlet extraction, often result in reduced yields because proanthocyanidins are heat-sensitive and susceptible to oxidation. To address these limitations, this review explores alternative modern extraction approaches. Relevant peer-reviewed articles were identified through a comprehensive search of five academic databases: ScienceDirect, PubMed, Google Scholar, NCBI, and BMC. The modern extraction techniques examined include Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE), Enzyme-Assisted Extraction (EAE), and Pressurized Liquid Extraction (PLE). Evidence from 23 selected studies shows that UAE and MAE are among the most effective and efficient methods for extracting proanthocyanidins from natural matrices. These findings underscore the potential of modern extraction technologies to improve both the yield and quality of proanthocyanidins, supporting their broader application in pharmaceutical and nutraceutical fields
HUBUNGAN ASUPAN ASAM LEMAK OMEGA-3 DENGAN KUALITAS TIDUR LANSIA
Full text linkLatar Belakang : Gangguan tidur sering terjadi pada lansia dan dapat menurunkan fungsi fisiologis serta kualitas hidup. Asam lemak omega-3, khususnya alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), dan docosahexaenoic acid (DHA) berperan dalam modulasi neurotransmiter, sintesis melatonin, dan proses antiinflamasi yang memengaruhi regulasi tidur. Namun, bukti ilmiah mengenai hubungan asupan asam lemak omega-3 dengan kualitas tidur lansia masih bervariasi.Tujuan : Menganalisis hubungan antara asupan asam lemak omega-3 dengan kualitas tidur pada lansia.Metode : Penelitian ini adalah penelitian cross sectional yang dilaksanakan di Posyandu Bulusan, Semarang, pada Mei 2025. Sampel adalah 47 responden lansia berusia > 60 tahun yang diambil menggunakan metode consecutive sampling. Asupan asam lemak omega-3 diambil dengan Semi Quantitative Food Frequency Questionnaire (SQ-FFQ), sedangkan kualitas tidur diambil dengan Pittsburgh Sleep Quality Index (PSQI). Variabel perancu dalam penelitian ini meliputi aktivitas fisik dan tingkat depresi, yang diukur dengan International Physical Activity Questionnaire Short Form (IPAQ-SF) dan Geriatric Depression Scale 15 (GDS-15). Analisis bivariat dilakukan menggunakan uji korelasi Spearman. Hasil : Sebanyak 20 responden (42,6%) memiliki asupan asam lemak omega-3 dalam kategori kurang, 14 responden (29,8%) dalam kategori lebih, dan 13 responden (27,7%) dalam kategori baik. Sebanyak 26 responden (55,3%) memiliki kualitas tidur baik, sedangkan 21 responden (44,7%) memiliki kualitas tidur buruk. Hasil analisis bivariat menunjukkan adanya hubungan yang bermakna antara asupan asam lemak omega-3 total dan kualitas tidur (p = 0,022). Hubungan serupa juga ditemukan pada asupan ALA (p = 0,032) dan EPA (p = 0,043). Namun, asupan DHA (p = 0,313), aktivitas fisik (p = 0,476), dan tingkat depresi (p = 0,314) tidak menunjukkan hubungan yang signifikan dengan kualitas tidur.Kesimpulan : Asupan asam lemak omega-3 total, ALA, dan EPA menunjukkan hubungan yang signifikan serta berkorelasi positif dengan kualitas tidur, sedangkan asupan DHA, aktivitas fisik, dan tingkat depresi tidak menunjukkan hubungan yang signifikan secara statistik terhadap kualitas tidur
Process Optimization of Heating Ovens for Energy Saving and Emission Reduction in Industrial Electrodeposition Painting
Full text linkThis study discusses efforts to improve the heating oven system in the painting process to increase energy efficiency, reduce operational costs, and lower CO₂ emissions without compromising product quality, including the deactivation of the Recuperative Thermal Oxidizer (RTO) to reduce energy consumption and CO₂ emissions. Prior to improvement, the heating process consisted of three separate stages—pre-heat, heat-up, and keep zone—with a total processing time of approximately 60 minutes. This configuration resulted in annual LNG consumption of 230,866 m³, significantly impacting energy costs and the carbon footprint of the production process. Through process engineering, these stages were simplified into a single rapid-heating phase up to a peak temperature of 180°C, followed by stabilization at 150°C with a total duration of around 18 minutes. This operational redesign reduced cycle time by nearly 50% while optimizing heat distribution inside the oven. The implementation produced significant results: LNG consumption decreased by more than 50%, energy costs dropped from IDR 1.49 billion to IDR 0.71 billion per year, and total CO₂ emissions were reduced from 417.87 tons to 199.56 tons within two years. Product quality evaluation confirmed that the process changes did not affect performance or compliance with specification standards. Additionally, this study recommends further development through data-driven optimization, integration of sensors and IoT for more precise automatic control, and opportunities to utilize renewable energy as part of sustainable manufacturing strategies

Full text linkMilkfish (Chanos chanos) cultivation faces challenges related to high feed costs and disease outbreaks caused by Vibrio bacteria. The use of natural ingredients containing bioactive compounds, such as Sonneratia alba mangrove leaves, as feed additives may serve as an effective solution. This study aimed to determine the effect of adding Pidada (S. alba) leaf extract at different doses to feed on growth performance and survival rates after infection with Vibrio harveyi. The experiment used a Completely Randomized Design (CRD) consisting of four treatments and three replications. The treatments included: A (control, artificial feed without extract), B (75 ppm per 500 g feed), C (125 ppm per 500 g feed), and D (170 ppm per 500 g feed). Treatment B produced the best biomass gain of 8.4 g, the best feed conversion ratio (FCR) of 1.16, and a feeding efficiency of 86.52 percent. The addition of S. alba leaf extract significantly improved growth and survival of milkfish infected with V. harveyi, with treatments B, C, and D maintaining a 100 percent survival rate after infection. Treatment A showed the lowest growth and survival, indicating that S. alba leaf extract positively supports fish health and enhances milkfish cultivation outcome
The Influence of Entrepreneurship Motivation and Self Efficacy on Agribusiness Students’ Entrepreneurial Intention
Full text linkThe growing number of university graduates in Malang, Indonesia, is not matched by the availability of formal job opportunities, encouraging many individuals to pursue entrepreneurship as a feasible career choice. Within the agribusiness sector, this opportunity remains largely untapped despite the abundance of local resources and market opportunities. The objective of this research is to examine how entrepreneurship motivation and self-efficacy affect the intention to become entrepreneurs among Agribusiness students at Brawijaya University. The research was conducted between October and December 2024 using a quantitative approach. Data were obtained from 80 active students with entrepreneurial experience using a structured questionnaire based on a Likert scale. The data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results reveal that both entrepreneurship motivation and self-efficacy have a significant and positive influence on entrepreneurial intention, with an R-squared value of 0.637. This implies that 63.7% of the variance in entrepreneurial intention is explained by the two independent variables. The most influential factor within entrepreneurship motivation is the influence of social conditions, while the strongest indicator of self efficacy is the belief in achieving business goals. These results suggest that a combination of strong internal drive and self-confidence is essential in fostering entrepreneurial behavior among students. The implication of this study is the need for universities to strengthen entrepreneurship programs by integrating real-world experiences, mentoring, and exposure to successful role models in agribusiness. Enhancing these elements may better prepare students to become innovative entrepreneurs who contribute to sustainable economic development.
Does healthy-chilli farming result in higher productivity and better farmers' term of trade than conventional farming?
No full textHealthy chilli farming has the potential to increase both the output and income of farmers in improving farmer’s welfare through GAP implementation. The welfare of farmers encompasses more than just income and production, hence, the Farmer’s Terms of Trade (FTT) serve as a reference point for household prosperity in Indonesia. This research aims to: (1) compare the productivity of chilli farmers, (2) examine the farmer’s terms of trade, and (3) analyze the impact of productivity and other factors on the farmer’s terms of trade associated with three farming methods: healthy, semi-healthy, and conventional farming systems. The study was conducted in Sleman Regency, Indonesia, a region that has been implementing healthy-chilli farming system since 2021. A total of 106 farmers were interviewed, distributed across 6 areas known for their significant chilli production. The respondents were selected through a simple random sampling approach. The FTT is assessed through household income and subsistence terms of trade. The comparison of farmer productivity was analyzed using a Kruskal-Wallis H test. The findings indicate that the productivity of healthy-farming is higher than other two chilli farming systems. The FTT for healthy- farming is higher and classified as prosperous, while others do not yet reach prosperous level. Moreover, subsistence terms of trade of healthy and conventional farming statistically different. The increase of FTT was significantly affected by productivity, planting area, and price of chilli, while the number of family member, non-family labor cost, and household expenditures can decrease the FTT
Analisis Morfometrik Dan Estimasi Tingkat Eksploitasi Ikan Hiu Yang Tertangkap Di Perairan Balikpapan Kalimantan Timur
Full text linkIkan hiu umumnya ditemukan di wilayah pesisir hingga kedalaman 200 meter sehingga rentan tertangkap oleh nelayan. Penelitian ini bertujuan mengidentifikasi spesies ikan hiu melalui analisis morfometrik serta mengestimasi tingkat eksploitasi Ikan Hiu Sirip Hitam (Carcharhinus limbatus) yang tertangkap di Perairan Balikpapan. Penelitian ini dilaksanakan selama periode bulan Desember 2024 hingga Mei 2025 dengan menggunakan metode purposive sampling yang bersumber dari hasil tangkapan nelayan setempat. Lokasi pengambilan sampel bertempat di Tempat Pendaratan Ikan (TPI) Filial Klandasan, Balikpapan, sedangkan analisis data dilakukan dengan menggunakan aplikasi FiSAT II. Hasil penelitian berhasil mengidentifikasi empat spesies ikan hiu yang tertangkap di perairan tersebut, yaitu Carcharhinus amblyrhynchos, Sphyrna lewini, Rhynchobatus australiae, serta Carcharhinus limbatus yang merupakan spesies dengan jumlah tangkapan terbanyak dibandingkan spesies lainnya. Mayoritas individu ikan hiu yang tertangkap masih berstatus juvenil atau belum dewasa, dengan total tangkapan terdiri atas 79 ekor betina dan 21 ekor jantan. Analisis hubungan panjang dan berat yang dilakukan pada spesies C. limbatus menunjukkan korelasi yang sangat signifikan dengan nilai koefisien korelasi r > 0,92, yang berarti terdapat keterkaitan yang erat antara panjang dan berat tubuh ikan. Estimasi tingkat eksploitasi pada spesies C. limbatus menghasilkan nilai E = 0,45, yang mengindikasikan bahwa spesies ini masih berada dalam kondisi underfishing atau tingkat eksploitasi yang tergolong rendah dan belum melampaui ambang batas optimal yang diperbolehkan, sehingga populasinya masih relatif aman dari ancaman penangkapan berlebihan
