Abstract

The aims of this research were to determine the hatching performance of snakehead fish egg which incubated at different water temperature. This research had been conducted in the Fish Breeding Unit “Batanghari Sembilan”, Indralaya South Sumatera Indonesia. This research was an experimental research with 5 treatments of water temperature P1 (26 ± 0.5°C), P2 (28 ± 0.5°C), P3 (30 ± 0.5°C), P4 (32 ± 0.5°C), P5 (34 ± 0.5°C) and 3 repetitions. The results showed that incubation period needed at P1: 30.01 hours, P2: 28.02 hours, P3:23.13 hours, P4: 21.03 hours, P5: 20.12 hours. The best treatment for hatching rate, normality and survival rate were P2 treatment, 86.33%, 100% and 97.3%, respectively.  Even though the fastest incubation period was the P5 treatment (20.12 hours). Water quality of the research was intolerance range, pH (4.17-5.32) and Dissolved Oxygen (6.23-6.71 mg.L-1). Based on the results acquired, incubation temperature at 28 ± 0.5°C produced the best hatching rate, normality, and survival rate.

Abstract

Organic liquid fertilizer is the source of nutrients.  This fertilizer can be used to improve the water quality.  It is enviromentally friendly  and relatively cheap.  Application of the fertilizer has been done on aquaculture.  At the tidal lowland areas, application of this fertilizer is mostly as soil improvement agent.  It is limited to be used as water quality improvement agent.  Tidal lowland has an acid soil with a low fertility level characters. The objectives of the study are to know the effect of liquid organic fertilizer to the water quality (temperature, pH, dissolved oxigen, ammonia) and to the amount of plankton in the ponds. This research was done at the reclaimed tidal lowland in Banyuasin District of South Sumatera, Indonesia.  The organic liquid fertilizer was made by fermentation of  both animals manures and vegetable waste with the percentage of N : P2O5 : K2O were 0.120 : 0.023 : 0.750.  Water quality data was taken three times in every three days (plankton) from the ponds that was added by liquid fertilizer with dose of 4.35 L /pond (P1) and 8.7 L/pond (P2).  All the water quality data were analyzed qualitatively.  The results show that on treated  ponds pH dropped slightly since the beginning with pH 6.0 and remain 6.4 - 6.8 in the last day.   The value of  Ammonia ranges 0.06-0.15 mg.L-1 and Dissolve oxigen range 1.9-2.5 mg.L-1‑.    Phytoplankton and zooplankton amount increased and reached the peak on day 12 (12033 ind.L-1 and 364 ind.L-1 respectively), and finally turned down slowly.  Therefore, liquid fertilizer addition should be given to the ponds more than once during fish rearing period.  It is  in order to increase the amount of  plankton and to manage the water quality in the reclaimed tidal lowlands ponds

Abstract

ABSTRACT Soybean meal is plant protein sources that often used in fish feed. However, availability of soybean meal still depend on imports. Therefore, need an alternative to reduce dependence on soybean meal. Tofu waste can be used as alternative plant protein source. The aim of this research was to determine the best percentage of  fermented tofu waste meal in feed formulation for optimal growth and feed efficiency of catfish (Pangasius hypophthalmus) juvenile. This research was conducted at Laboratorium Dasar Perikanan, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University on August to October 2014 and the feed proximate analysis conducted in Laboratorium Bioproses, Department of Chemical Engineering, Faculty of Engineering, Sriwijaya University, Indralaya. The method of this research used Completely Randomized Design (CRD) with 6 treatments and 3 replications, consist of A (commercial feed), B (0% fermented tofu waste meal : 20% soybean meal), C (5%  fermented tofu waste meal : 15% soybean meal), D (10% fermented tofu waste meal : 10% soybean meal), E (15% fermented tofu waste meal : 5% soybean meal), F (20% fermented tofu waste meal : 0% soybean meal). The result showed that the use of fermented tofu waste in the feed had not signifficant on the growth of weight and length, specific growth rate, feed convertion ratio, feed efficiency, and survival rate of catfish juvenile for each treatment. The best result was obtained by treatment D which used  fermented tofu waste meal 10%.   Keywords : Pangasius hypophthalmus, fermented tofu waste, soybean meal, feed efficiency, growth

Abstract

Tidal lowland is a potential land for aquaculture, however it should be manage intensively in order to give a good and sustainable contribution for society. Tidal fenomenon and rainfall will interacted with water quantity and quality which will used as fish media culture. Fish need optimal water to support its growth and survival. Based on measure and water analysis in two locations, at Mulyasari village, Tanjung Lago District, Banyuasin Regency, South Sumatera, tidal and rainfall gave effect to physical, chemical and biological of water quality and quantity. Related to the change of weather where in the second year (2016) the dry season was longer than rainy season since 2015,the rainfall was only about 200 mm- 310 mm/month. The lower of rainfall effected to the water level in canals and influent the brightness and turbidity, sea intrution that brought salinity about 5-15 ppt in the water.Acidity was also decline about 3.5-5 with ammonia- free reached 0.25 mg/L. Nitrate and nitrite were in common such a natural water condition, yet pyrite oxidized that caused the water and land tobe reddish yellow and looked like greasy in the surface. These condition would be harmfull for fish. The tidal and rainfall was also effect plankton abundance. The data shows that fitoplankton and zooplankton were higher in the canals than in the pond.

Abstract

Climbing perch is one of fresh water fish that has been started to be cultured, howeverthere are some problems occur such as low growth rate and high price of feed. Biofloc is atechnology that use bacteria which is able to destroy the waste and to maintain the water quality.Floc can be used as feed as well. This technology is capable to be applied even in the highdensity of fish rearing.T he aim of this research was to study the effect of biofloc technologyfor climbing perch culture with different densities. This research was conducted in the Muliasarivillage, Banyuasin District, South Sumatera Province since February to April 2015. TheCompletely Randomized Design (CRD) with five treatments and three replications wasapplied. The treatments were A : 100 fish/m2of density without biofloc technology, B : 100fish/m2of density with biofloc technology, C : 200 fish/m2of density with biofloc technology,D : 300 fish/m2of density with biofloc technology, E : 400 fish/m2of density with biofloctechnology. Results shown that the addition of biofloc provide significantl effect on floc, fishgrowth and feed conversion ratio. The best density was 400 fish/m2 with 5.8 mL/L of floc andfood conversion ratio 0.81, survival rate 73%, growth weight 2.77 gram and legth of 1.87 cm.

Abstract

Andini A, Cahya A, Ningsih AO, Iqbal M, Sugiarti S, Fitrani M.  2021. Intensive system fish farming waste conversion to biogas household scale. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 400-410.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Intensive system fish farming with high protein artificial feeding in a limited scope produces waste that can negatively impact if it is directly discharged to the waters. This study aimed to examine whether intensive fish farming waste can be converted into biogas, especially on a household scale, as an alternative in processing aquaculture waste. The method used by the researcher in the literature review method is due to the Covid-19 pandemic situation, which limits researchers from taking data. The results of the literature study state that aquaculture waste has the potential for methanogenic bacteria as the main component of biogas with an anaerobic decomposition process. The content of nitrogen (N2) and hydrogen sulfide (H2S) in aquaculture waste is also an additional component in biogas production. Household-scale biogas production was formed on day 4‒30 which consists of several processes such as hydrolysis, acetogenesis, acetogenesis, and methanogenesis. Biogas production results from fish farming waste can also be used as organic fertilizer for plants or agricultural land. Therefore, converting fish farming waste into biogas can be done as an effort to treat aquaculture waste. Suggestions from this research are necessary to re-examine directly in producing biogas to obtain more relevant data.
