Abstract

Title (Bahasa Indonesia): Rasio C:N pada media kultur cacing sutra, Tubifex sp. This study aimed to determine the C:N ratio on each medium for the growth of the sludge worm. This study used mud and soybean curd residue (treatment A), mud and chicken manure (treatment B), mud and pig manure (treatment C), and control (mud only) (K) as culture media of the sludge worm (Tubifex sp.). The decomposition process was proceeding for six days, and then the sludge worms were stocked with initial weight of 30 grams per container. Culture period was 21 days in running water systems. The resulting C:N ratio was 60.5 for treatment A, 45.8 for treatment B, 36 for treatment C and 35 for K. The soybean curd residue and mud medium gave the highest influence on the growth of the sludge worm, followed by pig manure and mud, chicken manure and mud, and then mud (control). Penelitian ini bertujuan untuk menentukan perbandingan C:N ratio dalam media budidaya untuk pertumbuhan cacing sutra. Penelitian ini menggunakan lumpur dan ampas tahu (perlakuan A), lumpur dan kotoran ayam (perlakuan B), serta lumpur dan kotoran babi (perlakuan C) dan perlakuan K (kontrol: hanya lumpur) sebagai media kultur cacing sutra (Tubifex sp). Proses dekomposisi dilakukan selama 6 hari, kemudian dilakukan penebaran cacing sutra dengan berat awal 30 gram/wadah penelitian. Waktu pemeliharaan dilakukan selama 21 hari dalam sistem air mengalir. Hasil penelitian menunjukkan rasio C:N sebesar 60,55 untuk perlakuan A, 45,85 untuk perlakuan B, 36,08 untuk perlakuan C, dan 35,25 untuk K. Media yang menggunakan ampas tahu dan lumpur memberikan pengaruh tertinggi terhadap pertumbuhan cacing sutra, kemudian disusul oleh media kotoran babi dan lumpur, media kotoran ayam dan lumpur dan terendah media lumpur (kontrol).

Abstract

Eels (Anguilla marmorata) can adapt to the temperature of 12-31 ° C but require an optimum temperature to support growth due to their slow growth. Low water temperature could also influence their appetite and be susceptible to disease. The water heater is needed in the location where source water is abundant but low temperature, such as Tatelu Freshwater Aquaculture Center with 22-25°C. This activity was aimed to increase the  the water temperature of eel enlargement treatment tank. The design began with making an easily operated-water heating working block system diagram and detailing low cost budget for good equipment production. This application gave a fairly good impact on the eel rearing, in which the eels were not susceptible to disease and  had stable appetite. The  temperature could be adjusted as desired by installing a microcontroller to save energy and prevent  overheating the media. For 1 ton of water with initial temperature of 25°C takes about 2 hours to produce a water temperature of 28 ° C.  To make a prototype water heater costs about  IDR 3 million for 450 watts of power and water flow of 25 liters/min. Ikan sidat (Anguilla marmorata) membutuhkan suhu optimal dalam budidaya agar mendukung pertumbuhannya yang cenderung lambat. Suhu air rendah dapat juga mempengaruhi nafsu makan dan potensi munculnya penyakit. Pemanas air dibutuhkan pada lokasi yang sumber airnya melimpah tetapi bersuhu rendah, seperti BBAT Tatelu yang memiliki kisaran suhu air 22 - 25°C. Kegiatan ini bertujuan untuk meningkatkan nilai suhu air pada bak treatment pembesaran ikan sidat. Perancangan dimulai dengan membuat diagram blok sistem kerja pemanas air dengan operasional yang mudah dan merinci anggaran agar didapatkan biaya yang murah dibandingkan peralatan sejenis produksi pabrikan. Hasil penerapan memberi dampak yang cukup baik dalam menunjang pemeliharaan ikan sidat. Selama masa pemeliharaan, benih sidat tidak mudah terserang penyakit dan nafsu makan stabil. Suhu yang dihasilkan dapat disesuaikan dengan keinginan dengan adanya penambahan alat mikrokontroller yang berfungsi memutus arus jika suhu mencapai batas yang diinginkan sehingga dapat menghemat energi dan mencegah terjadinya panas berlebih pada media pemeliharaan. Kisaran suhu yang dihasilkan untuk 1 ton air dengan suhu awal 25°C membutuhkan waktu sekitar 2 jam untuk menghasilkan suhu air 28°C. Untuk membuat prototipe pemanas air ini membutuhkan biaya sekitar 3 juta rupiah dengan daya 450 watt dan kecepatan aliran 25 liter /menit.

Abstract

This study aimed to 1) determine the best combination between ketapang and banana peels for the propagation of life feed mosquito larvae; 2) determine the culture media that can produce mosquito larvae optimally. The containers used in this study were 24 buckets with a size of 5 litres. Some of the materials used in the study were dried ketapang leaves, goroho banana peels, kepok banana peels and water. This study used a factorial Completely Randomized Design (CRD) consisting of two factors and three replications. The first factor was the difference in the number of ketapang leaves. The second factor was the difference in banana peels types. The first factor included the difference in the number of ketapang leaves, consisting of: Treatment 0 = without ketapang leaves, Treatment 1 = 50 grams of ketapang leaves, Treatment 2 = 75 grams of ketapang leaves, Treatment 3 = 100 grams of ketapang leaves. The second factor included differences in banana peels, which consist of: Treatment 1 = one kepok banana peel, Treatment 2 = one goroho banana peel. The results were different types of banana peels affected the numbers of mosquito larvae, where the best was kepok banana peels; the difference in weight of ketapang leaves did not have a significant effect on the number of mosquito larvae. The container used in this study was a bucket with a volume of 5 L. The banana peels used were goroho banana peels and ripe yellow kapok banana peels. Ketapang leaves were preapared with a weight 0f 0, 50, 75, and 100 grams, respectively. Shoe banana peels and  goroho banana, one skin eachand ketapang leaves 0, 50, 75, and 100 grams, respectively, put together wit the jalah used to wrap between ketapang leavesand spatu banana peels and goroho banana, then put into a container that has been filled wit 3 L of water.

Abstract

This study aimed to analyze the use of fermented rice bran media for the propagation of Alona sp. The method used is an experimental method, using one-way ANOVA, with three treatments, namely fermented rice bran media, unfermented rice bran media, and water. Each treatment was repeated 3 times, so that 9 experimental units were obtained. The observed variable was the density of Alona sp. The results showed that the density of Alona sp. that were cultured on fermented rice bran media was significantly different from that of unfermented rice bran and water.

Abstract

The purpose of this study was to examine the density of life feed Alona sp. on the media of water hyacinth leaf fermented with effective microorganism-4 (EM-4) solution. The method used was an experimental, using one-way ANOVA, with four treatments, namely fermented water hyacinth leaf media, unfermented water hyacinth leaf media, horse manure media, and water, each with three replications. The parameter observed was the density of Alona sp. The result showed that the density of Alona sp. cultured using fermented water hyacinth leaf media was significantly different from those cultured on unfermented water hyacinth leaf media.  It had also been found that the density of Alona sp. high in horse manure media. However, it is recommended to use fermented water hyacinth leaf media, because it is more hygienic. In addition, the availability of horse manure is increasingly rare

Abstract

This study aimed to determine the effect of different doses of EM-4 in feed on the growth and survival of tilapia. This research was conducted at the Center for Freshwater Aquaculture (BPBAT) Tatelu. The study was carried out from June to August 2021. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and each treatment had 3 replications. The treatment used was Probiotic EM-4 with different doses consisting of: A: 0 ml/kg feed, B: 15 ml/kg feed, C: 20 ml/kg feed, D: 30 ml/kg feed. The results of the study used the Analysis of Variance (ANOVA) using the SPSS application (22). Giving different doses of EM-4 in the feed gave a significantly different effect on the absolute weight growth of tilapia, but the results also showed that the administration of different doses of EM-4 in solid had no effect on absolute length growth, daily length growth rate, FCR and tilapia survival. The treatment that had an effect on the absolute weight growth of tilapia was found in the treatment with a dose of EM-4 15 mL/kg of feed with an absolute weight growth of 23.89 g.
