Abstract

This study aims to determine the immunity response of  Carassius auratus infected with Aeromonas hydrophila bacteria and post-treatment with propolis solution by measuring total leukocytes and phagocytosis index. The method used is experimental by applying a completely randomized design (CRD) with five treatments and three replications. The treatments were Kn (not infected with A. hydrophila and not treated with propolis), Kp (infected with A. hydrophila but not treated with propolis), while fish infected with A. hydrophila were treated with propolis doses P1 (700 ppm), P2 (800 ppm), and P3 (900 ppm). Treatment was done by injecting 0.1 ml of propolis into fish infected with A. hydrophila intramuscularly. The test material was 150 fish of 8-10 cm in size. The results showed that propolis significantly gave an immune response to the C. auratus infected with A. hydrophila (p<0.05). The 800 ppm propolis dose was the most effective, as indicated by a total leukocyte count of 3.70×104 cells/mm3, a phagocytosis index value of 28.33%, and a survival rate of 83.33%. This study highlights that propolis has potential as a natural immunostimulatory agent in enhancing non-specific defense mechanisms in C. auratus infected with pathogenic bacteria

Abstract

Chaetomorpha sp is a type of green marcoalgae that is rich in bioactive compound that function as antibacterial, anti-inflammatory and can increase fish immunity. This study aims to determine the immunostimulating effect of Chaetomorpha sp macroalgae extract on the leukocyte profile of Tilapia infected with A. hydrophila. The experimental method used a completely randomized design (CRD) with four extract dose treatments (0, 25, 50, 75 mL/kg feed) and three replicates. The test fish used were 2.63 0.26g, reared in black tanks with a size of 60x30x30 cm, a volume of 80 L with a stocking density of 1 fish/4 L, and a recirculation system. Maintenance was carried out for 60 days with a frequency of feeding three times a day, namely 08.00 AM, 01.00 PM, and 05.00 PM, as much as 5% of body weight. The parameters observed were total leukocytes, leukocyte differentiation, and phagocytosis index. The results showed that the administration of Chaetomorpha sp extract significantly increased total leukocytes, lymphocyte differentiation, and phagocytosis index (p0.05). The dose of 50 mL/kg feed is the optimal dose that affects the leukocyte profile of Tilapia. T0 (without extract) experienced 100% mortality, while the treatment group showed increased resistance to infection. Bioactive compounds such as sulfated polysaccharides and flavonoids in Chaetomorpha sp are thought to play a role in stimulating the innate immune system. This study highlights the potential of Chaetomorpha sp as an alternative to antibiotics in sustainable tilapia aquaculture.

Abstract

Ketimpangan distribusi sarana kesehatan di Indonesia masih menjadi persoalan dalam mewujudkan pemerataan layanan kesehatan. Penelitian ini bertujuan untuk memetakan visualisasi ketersediaan sarana kesehatan di tingkat desa/kelurahan per provinsi di Indonesia tahun 2024 dengan menggunakan analisis biplot. Data yang digunakan bersumber dari Badan Pusat Statistik (BPS) dan mencakup enam jenis sarana kesehatan di 38 provinsi. Hasil analisis Principal Component Analysis (PCA) menunjukkan bahwa dua komponen utama mampu menjelaskan 93,3% total variasi data. Komponen pertama (86,5%) didominasi oleh jumlah rumah sakit, rumah sakit bersalin, puskesmas, pustu, dan apotek. Komponen kedua (6,8%) mengindikasikan variasi pada persebaran puskesmas pembantu. Hasil biplot menunjukkan bahwa Provinsi Jawa Barat dan Jawa Timur memiliki ketersediaan sarana kesehatan yang tinggi, tercermin dari posisinya yang jauh ke arah positif pada Dim1. Sebaliknya, Papua Selatan, Papua Pegunungan, dan Gorontalo berada dekat titik pusat atau kuadran negatif, menandakan rendahnya jumlah fasilitas kesehatan. Provinsi Jawa Tengah terlihat sebagai outlier pada Dim2, yang mengindikasikan distribusi fasilitas yang tidak biasa. Hasil ini memberikan informasi visual yang berguna untuk mendukung kebijakan pemerataan sarana kesehatan nasional

Abstract

Pertumbuhan sektor akuakultur yang pesat telah menjadi respons terhadap meningkatnya permintaan protein hewani global, namun ekspansi yang tidak terkendali menimbulkan dampak negatif terhadap lingkungan, sosial, dan ekonomi. Konsep Blue Economy menawarkan kerangka pembangunan alternatif yang mengintegrasikan pertumbuhan ekonomi dengan pelestarian ekosistem kelautan. Review artikel ini bertujuan mensintesis literatur terkini mengenai penerapan pendekatan Blue Economy dalam manajemen budidaya ikan berkelanjutan. Kajian ini mengeksplorasi berbagai sistem produksi berkelanjutan seperti Integrated Multitrophic Aquaculture (IMTA), Recirculating Aquaculture Systems (RAS), dan aquaponik yang terbukti mampu mengurangi limbah, meningkatkan efisiensi sumber daya, dan mendiversifikasi produk. Implementasi Blue Economy juga mencakup dimensi sosial-ekonomi melalui pemberdayaan masyarakat lokal, pengembangan kapasitas, peningkatan akses pasar dan pembiayaan, serta penciptaan lapangan kerja. Hasil kajian menunjukkan bahwa pendekatan ini mampu mengurangi beban nitrogen hingga 40-50% dan fosfor hingga 30-40% melalui sistem IMTA, serta menghemat konsumsi air hingga 99% melalui RAS. Meskipun menjanjikan, implementasi masih menghadapi hambatan berupa keterbatasan investasi, kompleksitas regulasi, dan kurangnya kapasitas pembudidaya. Kajian ini memberikan kontribusi konseptual dalam memperkuat integrasi Blue Economy pada praktik budidaya ikan di Indonesia melalui tata kelola berbasis teknologi dan inklusivitas sosial

Abstract

Lift-net fishermen in Gampong Lhok Layeun, Leupung Sub-district, Aceh Besar District, still use mercury lamps which are energy-intensive, require high operational costs, and are less effective in attracting fish. This condition leads to low profits for fishermen. To address this problem, a community service program was conducted in the form of training and assistance in the development of underwater light emitting diode (LED) as an alternative technology that is more energy-efficient and effective. This activity aimed to enhance fishermen’s capacity in mastering appropriate technology and reducing fishing operational costs. The program was held on August 23–24, 2025, at the Layeun Village Office Hall, involving 15 fishermen, three lecturers, and three students from Universitas Syiah Kuala. The implementation method applied an applicative and participatory approach through several stages: preparation, training, hands-on practice, and evaluation. Participants received materials on the concept and advantages of underwater LED, followed by direct assistance in assembling the devices and conducting simple trials. The results showed an increase in fishermen’s understanding of the differences between lighting technologies as well as their ability to assemble underwater LED devices independently. Fishermen expressed their readiness to adopt this technology because it is more energy-efficient, reduces operational costs, and has the potential to increase fish catches. In conclusion, this program successfully improved fishermen’s knowledge and skills in utilizing underwater LED technology, which can serve as an alternative solution to enhance the welfare of coastal communities and support sustainable fisheries resource management.

Abstract

Chaetomorpha sp. is a green macroalgae that contains various bioactive compounds with antibacterial and anti-inflammatory activities, as well as the potential to improve the physiological health of fish. This research investigates how incorporating Chaetomorpha sp. extract into the diet influences the hematological parameters of Tilapia (Oreochromis niloticus) challenged with Aeromonas hydrophila. The study used a completely randomized design (CRD) with four levels of extract supplementation (0, 25, 50, and 75 mL/kg of feed), with each treatment replicated three times. The hematological parameters analyzed included total erythrocytes, hematocrit, hemoglobin, and blood glucose. The findings indicated that adding Chaetomorpha sp. extract to the diet significantly (p<0.05) improved all hematological indicators relative to the control, with 50 mL/kg of feed as the most effective dosage. The highest erythrocyte count 1.89 x106 cells/mm3, hematocrit value 35.67%, and hemoglobin concentration 6.87 g/dL were observed in fish fed 50 mL/kg extract. This increase in hematological values indicates improved oxygen transport capacity, physiological condition, and metabolic response in fish. Bioactive constituents, including sulfated polysaccharides and flavonoids, are believed to enhance the hematological condition of fish. These findings confirm the potential of Chaetomorpha sp. as a natural supplement to support Tilapia health in sustainable aquaculture systems.

Abstract

CORRESPONDENCE ANALYSIS OF THE RELATIONSHIP PATTERN BETWEEN DISASTER TYPES AND VICTIM STATUS IN SUMATERA IN 2024 This study analyzes the relationship between provinces, types of disasters, and types of disaster victims in 10 provinces on Sumatra Island using correspondence analysis. The data includes seven disaster types and five victim categories from Aceh, North Sumatra, West Sumatra, Riau, Riau Islands, Jambi, Bengkulu, South Sumatra, Bangka Belitung Islands, and Lampung. Descriptive results show floods as the most frequent disaster, while the "suffering victims" category appears most often. The chi-square test yields a p-value < 2.2e-16, indicating significant relationships between all variable combinations. The correspondence plot reveals distinct patterns: Lampung often faces extreme weather and earthquakes; West Sumatra and Riau are prone to landslides; Riau Islands and Aceh to forest and land fires; and Bengkulu to drought. Victim distribution also varies, West Sumatra reports more displaced victims, while most other provinces have predominantly suffered victims. In terms of disaster impacts, landslides are linked to fatalities, forest and land fires to displacement, and floods to suffering and missing victims. These findings highlight the interconnectedness of regions, disaster types, and victim impacts, offering important insights for disaster risk management and mitigation efforts across Sumatra.

Abstract

The coastal areas of Aceh Besar have high fisheries potential, but traditional fishermen using bagan boats in Gampong Lhok Layeun are facing declining catches due to technological limitations. The conventional lights used have limited light coverage and high fuel consumption. This service activity aims to improve the knowledge and skills of fishermen through education on energy-efficient underwater Light Emitting Diode (LED) technology as an alternative solution. The implementation method includes four stages: initial survey, socialisation, discussion, and evaluation and monitoring. The activity involved 25 participants consisting of fishermen, Panglima Laot, academics, and village officials. The results showed an increase in participants' understanding of underwater LED technology, with an average pre-test score of 57 increasing to 84 in the post-test. A total of 100% of participants expressed interest in adopting this technology, and showed high enthusiasm during the socialisation and discussion. This activity proves that participatory and educative approaches can strengthen traditional fisheries innovation at the local level.
