Abstract

Limbah sayuran, meskipun potensial mencemari lingkungan, dapat diubah menjadi sumber nutrisi yang bernilai dengan mengolahnya menjadi pupuk organik cair (POC) yang dapat mendukung pertumbuhan mikroalga Chlorella sp. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi POC limbah sayuran terhadap kepadatan sel Chlorella sp. Melalui rancangan acak lengkap dengan lima variasi konsentrasi (4 mL L-1, 5 mL L-1, 6 mL L-1, 7 mL L-1 dan 8 mL L-1) dan tiga ulangan, kami mengevaluasi efeknya selama 20 hari terhadap parameter seperti kepadatan sel, laju pertumbuhan spesifik, biomassa, serta penyerapan nutrien dan kualitas air. Hasilnya mengungkapkan bahwa konsentrasi POC limbah sayuran secara signifikan memengaruhi kepadatan sel Chlorella sp., dengan perlakuan terbaik tercapai pada konsentrasi 5 mL L-1. Pada hari ke-14, kepadatan sel mencapai 893,33 ± 5,78 ×104 sel mL-1, dengan biomassa sebesar 0,38 ± 0,00 g L-1 dan laju pertumbuhan spesifik sebesar 0,09 hari-1. Kesimpulan dari penelitian ini menegaskan bahwa konsentrasi POC limbah sayuran 5 mL L-1 optimal untuk kultur Chlorella sp., memberikan kontribusi penting dalam pengembangan solusi berkelanjutan untuk pengelolaan limbah dan produksi biomassa mikroalga.Vegetable waste, despite its potential environmental pollution, can be transformed into a valuable nutrient source by processing it into liquid organic fertilizer (LOF) that can support the growth of the microalga Chlorella sp. This study aims to analyze the effect of vegetable waste LOF concentration on the cell density of Chlorella sp. Through a completely randomized design with five concentration variations (4 mL L-1, 5 mL L-1, 6 mL L-1, 7 mL L-1, and 8 mL L-1) and three replicates, we evaluated its effects over a period of 20 days on parameters such as cell density, specific growth rate, biomass, nutrient uptake, and water quality. The results revealed that the concentration of vegetable waste LOF significantly influenced the cell density of Chlorella sp., with the best treatment achieved at a concentration of 5 mL L-1. On day 14, the cell density reached 893.33 ± 5.78 ×104 cells mL-1, with a biomass of 0.38 ± 0.00 g L-1, and a specific growth rate of 0.09 day-1. The conclusion of this research confirms that a concentration of 5 mL L-1 of vegetable waste LOF is optimal for Chlorella sp. culture, providing a significant contribution to the development of sustainable solutions for waste management and microalgae biomass production.

Abstract

Salah satu ikan air tawar yang bernilai ekonomi tinggi di Asia Tenggara adalah ikan baung (Hemibagrus nemurus). Namun dalam memenuhi permintaan masyarakat, permasalahan yang sering dihadapi pembudidaya adalah besarnya biaya pakan, sehingga perlu adanya pemberian pakan buatan berbahan dasar lokal yang murah dan mudah didapat. Tujuan dari penelitian ini untuk melihat pengaruh pemberian pakan buatan berupa kombinasi fermentasi ampas sagu dan tepung kepala ikan teri (Stolephorus indicus) dengan persentase yang berbeda terhadap kelulushidupan dan pertumbuhan benih ikan baung. Percobaan ini menggunakan rancangan acak lengkap (RAL) satu faktor dengan empat tingkat perlakuan, yaitu P1 pemberian pakan sebanyak 6%, P2 (8%), P3 (10%), dan P4 (12%) dari bobot tubuh ikan uji dengan tiga ulangan. Hasil penelitian menemukan bahwa persentase pemberian pakan uji kombinasi fermentasi ampas sagu dan tepung kepala ikan teri hingga 10 % dapat meningkatkan pertumbuhan benih ikan baung, namun bila ditingkatkan menjadi 12% pertumbuhan mengalami penurunan. Secara statistik persentase pemberian pakan uji berpengaruh nyata (P<0,05) terhadap bobot mutlak dan laju pertumbuhan harian benih ikan baung. Dari hasil penelitian dapat disimpulkan bahwa persentase pemberian pakan fermentasi ampas sagu dan tepung kepala ikan teri sebanyak 10% dari bobot tubuh ikan baung optimal untuk meningkatkan pertumbuhan karena sesuai dengan kebutuhan nutrisi ikan baung. Pakan ini dapat dikembangkan sebagai pakan berbahan baku lokal untuk ikan baung karena mudah diperoleh, harganya murah, dapat menekan biaya produksi, dan tersedia berkesinambungan.One of high value freshwater fish in Southeast Asia is the Asian redtail catfish (Hemibagrus nemurus). However, to meet the public demand, the frequently problem faced by farmers is the high cost of feed, so it is necessary to provide artificial feed based on local ingredients that are cheap and easy to obtain. The aim of this study was to determine the effects of feeding of an artificial feed in the form of a combination of fermented sago dregs and anchovy head meal (Stolephorus indicus) at different percentages on the survival and growth of the Asian redtail catfish. This study used a one-factor completely randomized design (CRD) with four treatment levels, namely P1 feeding as much as 6%, 8% (P2), 10% (P3), and 12% (P4) of the test fish's body weight triplicates. The results of this study showed that feeding of the test feed up to 10% could increase the growth of Asian redtail catfish fry, but when it was increased to 12%, growth decreased. Statistically, the percentages of feeding of fermented sago dregs and anchovy head meal as much as 10% of Asian redtail catfish body weight was optimum to increase, because it meets the nutritional requirements of Asian redtail catfish (P<0.05). From the results of the study, it can be concluded that the percentage of feeding fermented sago waste and anchovy head meal as much as 10% of the body weight of Asian redtail catfish is optimal for increasing growth because it is in accordance with the nutritional needs of Asian redtail catfish. This feed can be developed as the feed based on local ingredients for Asian redtail catfish because it is easily obtained, the price is cheap, it can reduce production costs, and it is available continuously.

Abstract

Perikanan budidaya merupakan salah satu sektor yang memiliki peluang dalam peningkatan ekonomis masyarakat. Keberhasilan usaha budidaya ikan salah satunya bergantung terhadap pengendalian penyakit ikan. Penyakit infeksi dapat menimbulkan gangguan, baik secara langsung maupun tidak langsung hingga menyebabkan kematian pada ikan. Dalam pengobatan penyakit ikan yang disebabkan oleh mikroba selalu menggunakan antibiotik, namun penggunaan antibiotik ini dapat menimbulkan efek negatif pada ikan dan lingkungan. Alternatif yang dapat dilakukan untuk mengurangi penggunaan antibiotik ini adalah menggunakan bahan alami dari tanaman yang memiliki senyawa antibakteri seperti tanaman daun senduduk bulu (Clidemia hirta). Tujuan pelatihan ini adalah memberikan pengetahuan bagaimana mengekstrak bahan antibakteri dari tanaman kepada siswa SMK 1 Bengkalis. Metode pelatihan yang diberikan kepada para siswa ini adalah pemberian materi secara teori dan praktek. Hasil pelatihan diperoleh ekstrak daun senduduk bulu mengandung senyawa fenolik, terpenoid, saponin, dan flavonoid. Hasil uji daya hambat ekstrak daun senduduk bulu dapat menghambat pertumbuhan bakteri Edwarsiella tarda sebesar 21,5 mm, Aeromonas salmonicida 20,5 mm, dan Pseudomonas aeruginosa 23,5 mm. Hasil kegiatan ini menunjukkan peningkatan pemahaman dan pengetahuan siswa terhadap proses ekstraksi pada tanaman.
