Abstract

Diabetes merupakan salah satu penyakit tidak menular yang prevalensinya terus meningkat di Indonesia. Ketergantungan masyarakat terhadap beras putih sebagai pangan pokok berkontribusi pada tingginya asupan karbohidrat berindeks glikemik tinggi yang berpotensi memicu lonjakan kadar gula darah. Pemanfaatan pangan lokal seperti rumput laut dan sagu menjadi alternatif potensial dalam upaya pencegahan diabetes. Rumput laut memiliki kandungan serat dan senyawa bioaktif yang mampu memperlambat penyerapan glukosa, sedangkan sagu memiliki indeks glikemik rendah serta mengandung pati resisten yang bermanfaat bagi pengendalian gula darah. Program Pengabdian kepada Masyarakat (PKM) ini dilaksanakan untuk memberikan edukasi kepada masyarakat mengenai bahaya diabetes, manfaat pangan lokal, dan pengenalan inovasi beras analog berbahan dasar rumput laut dan sagu. Kegiatan dilakukan melalui sosialisasi, demonstrasi, dan penyebaran kuesioner. Hasil kegiatan menunjukkan peningkatan pemahaman peserta mengenai hubungan pangan dengan risiko diabetes serta meningkatnya minat masyarakat untuk mencoba beras analog sebagai alternatif pangan yang lebih sehat.

Abstract

Selenium (Se) merupakan mikronutrien esensial dalam nutrisi ikan yang berperan dalam pertahanan antioksidan, regulasi sistem imun, fungsi metabolisme, dan peningkatan performa pertumbuhan. Namun, sumber selenium konvensional, baik dalam bentuk anorganik maupun organik, memiliki keterbatasan terkait bioavailabilitas, rentang dosis aman yang sempit, serta potensi toksisitas pada dosis berlebih. Perkembangan nanoteknologi telah memperkenalkan nanopartikel selenium atau selenium nanoparticles (SeNPs) sebagai alternatif suplemen pakan yang menjanjikan karena ukuran partikelnya yang kecil, luas permukaan yang tinggi, dan aktivitas biologis yang lebih baik. Kajian sistematis ini bertujuan mengevaluasi peran SeNPs dalam pakan ikan serta pengaruhnya terhadap performa pertumbuhan, status antioksidan, bioavailabilitas, kualitas daging, dan risiko toksisitas pada spesies akuakultur. Kajian dilakukan dengan pendekatan PRISMA melalui analisis artikel ilmiah bereputasi yang diterbitkan pada periode 2015–2025. Studi yang dianalisis terutama mencakup penelitian in vivo pada berbagai spesies ikan budidaya. Hasil sintesis menunjukkan bahwa suplementasi SeNPs pada dosis rendah hingga sedang meningkatkan laju pertumbuhan spesifik, efisiensi konversi pakan, aktivitas enzim antioksidan seperti GPx, SOD, dan CAT, serta ketahanan terhadap stres oksidatif dan infeksi patogen. Selain itu, SeNPs meningkatkan retensi selenium pada jaringan otot, profil protein, stabilitas oksidatif lipid, dan preservasi asam lemak tak jenuh ganda. Dibandingkan dengan sumber selenium konvensional, SeNPs umumnya menunjukkan bioavailabilitas yang lebih tinggi. Namun, gejala toksisitas dilaporkan pada dosis berlebih, sehingga standardisasi ukuran partikel, formulasi dosis, dan evaluasi keamanan jangka panjang diperlukan sebelum aplikasi komersial skala luas.

Abstract

Penanganan vibriosis menggunakan bahan alami seperti ekstrak Sargassum sp. pada kegiatan budidaya ikan kerapu cantang perlu diteliti. Pengujian efektifitas pelarut dalam menghasilkan senyawa fitokimia sebagai antibakeri dan modifikasi proses ekstraksi menjadi lebih sederhana bertujuan agar dapat ditiru oleh pembudidaya dilapangan. Isolat bakteri uji diisolasi langsung dari ikan yang memiliki gejala vibriosis dari ikan kerapu cantang pembudidaya di Senggarang Besar, Kota Tanjungpinang. Pengujian aktivitas antibakteri dari ekstrak Sargassum sp. dalam menghambat pertumbuhan Vibrio sp. dilakukan melalui uji zona hambat metode difusi kertas cakram (metode Kirby-Bauer). Hasil penelitian menunjukkan penggunaan pelarut alkohol 70% pada proses ektraksi memberikan hasil diameter zona hambat yang jernih dan lebih baik yaitu 13 mm pada konsentrasi tertinggi dari perlakuan (10%) dibandingkan dengan ekstrak yang menggunakan pelarut alkohol 96% pada konsentrasi yang sama yaitu 11.67 mm dengan catatan zona hambat yang terbentuk tergolong parsial karena tidak jernih atau bening sempurna akibat masih terdapat pertumbuhan bakteri yang tipis di dalam zona meskipun bentuk lingkaran zona hambat terlihat cukup jelas. Penggunaan pelarut alkohol 70% dapat digunakan untuk proses ekstraksi Sargassum sp. dengan pertimbang harga yang lebih murah dan hasil yang lebih baik dibandingkan alkohol 96% berdasarkan hasil yang ditunjukkan melalui penelitian ini.

Abstract

Sea cucumber (Holothuria scabra) contains lots of collagen and vitamin E for the pharmaceutical and cosmetic industries. H. scabra have high economic value. The price in the local market is IDR 400,000-1,200,000/kg and internationally it is IDR 500,000-IDR 5,000,000/kg dry weight. The level of exploitation is high, and it is suspected that there has been overfishing in several areas. Cultivation efforts need to be done to maintain the population in nature. The natural rate of gonad maturation and spawning in H. scabra broodstock is relatively slow, so efforts are needed to speed it up, among other things by administering hormones. This study aimed to stimulate (1) gonad maturation and (2) H. scabra spawning. The study used a completely randomized design (CRD) with 3 treatments and 3 replications in 2 stages using broodstock measuring 250-350 g/head. Stage 1: (1) Treatment A: without immersing the H. scabra in hormone solution, (2) Treatment B: immersing the H. scabra in the Oodev®/Oocyte developer dose of 1 mL/kg weight, and (3) Treatment C: soaking sea cucumber broodstock in Oodev® dose of 2 mL/kg weight. Stage 2: (1) without immersion of the broodstock in hormone solution, (2) immersion of the broodstock in Ovaprim® doses of 1 mL/kg weight. The data obtained were analyzed by analysis of variance. The results showed that immersion of H. scabra broodstock in Oodev® and ovaprim® was not successful in stimulating gonad maturation and spawning in H. scabra broodstock. The spawning behavior of sea cucumbers that were successfully observed included body movements such as writhing, coiling like a ball, sticking to walls, partially erecting their bodies, actively crawling, and being more active at night.Keywords: Gonad; Holothuria scabra; Oodev®; Ovaprim®; Spawning; Sea cucumber.

Abstract

The change in color in fish is influenced by the presence of changes in the amount of pigments. The use of carrots to enhance the brightness of color in Black Photon clownfish shows promising potential, considering that clownfish cannot produce color pigments on their own. This research aims to determine the effect of adding carrot powder to the feed and find the optimal dosage of carrot powder for enhancing the color brightness of Black Photon clownfish. The study was conducted from January to February 2023 at the Balai Perikanan Budidaya Laut (BPBL) in Batam, Setokok Island, Bulang Subdistrict, Batam City, Riau Islands Province. The research method employed was an experimental design using a Completely Randomized Design (CRD) with 6 treatments and 3 replications, namely K (control), A (5% carrot), B (10% carrot), C (15% carrot), D (20% carrot), E (25% carrot). The research results showed that the highest change in the black color's RGB index value was found in treatment E (25% powder addition), indicating a decrease in the black color's RGB index value in all treatments, and the addition of carrot powder influenced the change in the black color's RGB index value. On the other hand, the highest change in the white color's RGB index value was found in the Control (without powder addition) treatment, and the white color's RGB index value increased in all treatments, while the addition of carrot powder had a relatively less significant impact on the change in the white color's RGB index value.

Abstract

Silver pompano (Trachinotus blochii) is a fish that is in high demand and requires a large amount of production. The amount of production will be achieved if the fish is in a healthy condition. The health condition of the fish can be seen from its blood profile. Ginger is one of the herbal ingredients that can be used to improve the health of silver pompano, because it can stimulate fish health that can be seen through blood profile. This study aims to determine the effect of ginger on the blood profile of silver pompano and get the best dose. This study used a complete randomized design (CRD) method with 4 treatments, namely Control (without the addition of ginger powder), A (addition of ginger powder 3 gr/kg feed, B (addition of ginger powder 3.75 gr/kg feed and C (addition of ginger powder 4.5 gr/kg feed) each treatment was repeated three times. The silver pompano used were 144 fish with an average weight of 18-19 grams which were reared for 14 days with 2 times a day feeding in Teluk Air, Setokok Island, Batam while blood profile observations were made at the Fish Health and Environmental Testing Laboratory BPBL Batam. The results showed a significant effect on red blood cells, hemoglobin, white blood cells, monocyte percentage at a dose of 3.75 gr/kg feed. While for growth there was no real effect, but the highest average was obtained from treatment C with a dose of 4.5 gr/kg feed. Ginger powder as much as 3.75 gr/kg feed gave the greatest effect on the growth of the fish. Keywords: Silver Pompano, Ginger, Feed, Blood Profile
