Abstract

Chlorella sp. as a source of nutrition for aquatic organisms. Chlorella sp. is one way to meet the needs of aquatic organism feed. In the culture of Chlorella sp., light plays an important role in the process of photosynthesis. The photoperiod of the light will affect the density of cells and chlorophyll produced by Chlorella sp. Therefore, it is necessary to analyze cell density and chlorophyll content with different lighting periods. The purpose of this study was to determine cell density and chlorophyll-a content with different light photoperiode in Chlorella sp. culture laboratory scale. This study was used a complete randomized design with 3 treatments (A (12T: 12G), B (16T: 8G), and C (20T: 4G) and 6 replications. The results show that treatment B (16T: 8G) produces the highest cell density ( 1733.5 x 104 cells / ml) while the highest chlorophyll-a content in treatment A (12T: 12G) was 9.76 μg / ml.

Abstract

This study aims to determine the perception of fisheries business operators on the performance of fisheries extension workers needed by fisheries business operators in Bontoa District, Maros Regency. The method used is descriptive survey method with a purposive sampling approach. The results obtained indicate that the existence of fisheries extension workers in the Bontoa District of Maros Regency is still highly expected by fisheries businesses in this region, so that fisheries extension workers must have the ability, and be prepared to respond to the needs of fisheries business operators. In addition, fisheries instructors must be able to master and utilize information, communication and education technology, so that its existence has meaning for fisheries businesses in their working area. The method of fisheries extension that is in demand by fishery business actors from fisheries extension is to provide examples of businesses that have succeeded as a form of motivation for fisheries businesses to improve the production capabilities of fisheries businesses in Bontoa District, Maros Regency.

Abstract

Soaking beef jerky can improve chemical quality, flavor and consumer acceptance of the products produced. Liquid smoke functions as a preservative, a specific flavor and aroma. The research aims to analyze the chemical quality and antioxidant activity of beef jerky that has been soaked with the addition of liquid coconut shell smoke. The study used a Completely Randomized Design (CRD) with 5 treatments (D0 = jerky without soaking and adding liquid smoke, D1 = jerky with 2 hours soaking and adding 1% liquid smoke, D2 = jerky with 4 hours soaking and adding 1% liquid smoke, D3 = beef jerky with 6 hour soaking and 1% liquid smoke addition, D4 = jerky with 8 hour soaking and 1% liquid smoke addition) and 3 replications. Levels of protein, fat, water and antioxidant activity of beef jerky were observed in this study. Data were analyzed variance (ANOVA) with Duncan's further test. Immersion treatment and addition of coconut shell liquid smoke on beef jerky showed a chemical quality that was not statistically different in all treatments, but an increase in protein content (34.28% - 39.28%), fat content (3.98% - 5 , 25%), water content (11.02% - 12.33%) and antioxidant activity (355.23% - 201.98%).

Abstract

The research aims to analyze the income and business feasibility of selling chicken fodder in Palu City. The study was conducted in Palu City, from January-Februari 2019. The study used a model of revenue analysis and business feasibility analysis with R / C (Revenue Cost Ratio) and Break Event Point (BEP) criteria. The results showed that the average business income of selling chicken feed in Palu City was Rp10,133,419,048/year. The feasibility test of the average chicken feed sales business in the city of Palu by using criteria (RC Ratio)> 1, then the business was declared feasible with a value of R / C = 25.5 and the Break Event Point (BEP) resulted in a positive value.

Abstract

Kaledo is a byproduct of cow, which is a leg bone that contains fat and calcium, but some people avoid kaledo fat for health reasons. The purpose of this study was to determine the profile of fatty acids, calcium (Ca) and the level of organoleptic preference of blackheads. This study consisted of 2 treatments and 3 replications (Ka = kaledo without the fat layer removed) and Kb = the layer of fat kaledo removed). The parameters observed were the profile of fatty acids, calcium (Ca) and organoleptic tests. The results showed the profile of Ka fatty acids consisted of SFA (butyrate, laurate, tridecanoate, myristate, pentadecanoate, palmitate, margarate, stearic, arachidate, heneicosanoate, and behenate), Kb did not have laurate and heneicosanoate; MUFA Ka (miristoleate, cis-10 pentadecanoate, palmitoleate, cis-10 heptadecanoate, oleate, cis-11 eicoceneoate, erucate, nervonate and elaidate), Kb does not have erukate and PUFA (linolelaidat, linoleat, linolenat, eikosadinoat, eikosatrinoat, EPA dan DHA). The average calcium Kb (0.35%) is higher than Ka (0.03%). Panelists like the same aroma, color, texture and taste as Kb. Cooling for 2 hours at 7ºC showed an increase in SFA (palmitate and stearate) and organoleptic quality similar to Ka. SFA is dominated by palmitate and stearate, MUFA is oleic and elaidate, PUFA is linoleic and EPA. The highest calcium Kb is still below the standard for total adult consumption. Panelists like all treatments of blackheads (Ka and Kb)

Abstract

Seaweed is one of the coastal resources that has high economic value and is an export commodity of Indonesian fisheries. The problem that is often faced in seaweed cultivation is the availability of quality seeds and available continuously. One effort to meet the needs of seedlings is to apply tissue culture techniques. The purpose of this study was to study and determine the growth of seaweed (Eucheuma cottonii) by giving various doses of PES (Provasol Enriched Seawater). This research was conducted in August to September 2017 at the Network Culture Laboratory, Lombok Aquaculture Fisheries Center (BPBL), Gili Genting Sekotong Barat Hamlet, West Lombok Regency, West Nusa Tenggara Province. The research method was an experiment with 5 treatments of PES fertilizer doses (A: 0 ml; B: 3.5 ml; C: 6 ml; D: 8.5 ml; E: 11 ml) and 4 replications that were designed using a Randomized Complete Design (CRD). Data were analyzed using ANOVA. The results showed the highest specific growth rate, absolute weight and absolute length in treatment D (8.5 ml dose) with a value of 0.030% / week, respectively 0.35 g and 1.41 cm.

Abstract

This study aims to identify the diversity (polymorphism) of the Growth Hormone (GH) gene in Palu sheep as a potential candidate gene that controls the nature of growth. Sheep blood samples from the location of community farms (Palu, Central Sulawesi) which were used as many as 55 animals, were extracted to obtain genomic DNA samples. The detection of diversity in the GH gene was carried out using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP approach with the HaeIII enzyme). The DNA genome was extracted using the phenol-chloroform protocol and amplified with the polymerase chain reaction (PCR) technique, then the product PCR was cut with enzymes. Fragment fragments of the GH-HaeIII locus GH gene (GG-CC) were detected by the silver staining method. A base with a length of 288 bp (PB) from the GH gene was successfully amplified from Palu local sheep. The HaeIII cutting enzyme cuts the PCR product into two different fragments sequentially at 192 and 96 and is expressed as the B allele or BB genotype (homozygous). In conclusion, GH-HaeIII BB locus (homozygous). The restriction results for all PCR products obtained uniform results (no polymorphism) in other words all samples of Palu sheep in a monomorphic state. The DNA pattern in the GH gene is not appropriate for use as a Marker Assisted Selection, because it is monomorphic.
