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.

Abstract

CpG DNA is a kind of DNA synthetic immunostimulant containing CpG motifs consisting of short sequences containing one or more CpG motifs which act as a danger signal to the natural and innate immune systems. This study aimed to analyze the ability of CpG DNA to increase Interleukin 1β (IL1β) gene expression in tiger grouper so that it could be used as immunostimulant. Analysis of the expression level was carried out by extracting RNA- from the cephalic kidney which was treated with CpG DNA or with PBS as a control. Complementary DNA (cDNA) synthesis was carried out using the Ready To Go You Prime First Strand Beads (GE Healthcare) kit using the RT-PCR technique. The PCR product was analized by measuring the photostimulated luminescence value using UN SCAN IT software based on the thickness of the DNA fragments. The gene expression level and photostimulated luminescence value of the IL1β gene were higher than that of the PBS treatment used as a control. The luminescence value of the photostimulated IL1β gene in CpG DNA treatment was 113684 while the PBS treatment as a control was only 95610.

Abstract

This study aims to determine the body weight gain in the consumption of dry matter, the efficiency of the use of dry matter, blood glucose levels and blood urea levels of local goat which were fed with different frequencies. The test organisms were 15 local female goats aged 10 months and body weight of 14–20 kg. This research was an experimental study using a completely randomized design (CRD) with three treatments and 5 replications. The treatments tried were: P1 = Feeding 1.5% concentrate and 1.5% dry matter forage given once at 07.00 (UTC+8) based on body weight; P2 = 0.75% concentrate and 0.75% dry matter forage given at 07.00 (UTC+8), 13.00 (UTC+8) given 0.75% concentrate and 0.75% dry matter forage based on body weight; P3 = Feeding 0.5% concentrate and 0.5% forage dry matter is given at 07.00 (UTC+8), and at 13.00 (UTC+8) given 0.5% concentrate and 0.5% and at 19.00 (UTC+8) given 0.5% concentrate and 0.5% for dry matter based on body weight. The results of this study indicated that the frequency of feeding did not have an effect on dry matter consumption and blood urea levels, however, 2 times feeding significantly increased body weight gain, ration efficiency and blood glucose levels of local goat.

Abstract

The research aimed to sex ratio and size at first maturity of snakehead gudgeon at Bolano Sau Lake. The research was conducted at Bolano Sau Lake from August to December 2019. Snakehead gudgeon samples were obtained from the fishermen using a gillnet with a mesh size 2½-3½ inches. Sample analysis was carried out at the Water Quality Laboratory, State College of Fisheries and Marine, Palu. The difference in sex ratios of snakehead gudgeon used the Chi-square test, while the size at first maturity was estimated based on the Spearman - Karber method. Snakehead gudgeon caught on a gillnet in Bolano Sau Lake measuring 79-163 mm. The sex ratio between males and females is not balanced where males are more dominant in females. The size at first maturity was 119.19 mm. Suggestion minimum legal size > 120 mm. The use of gillnets in snakehead gudgeon fishing activities has an effect on the balance of male and females, but is very selective with size.
