Abstract

Feeding broiler chickens will have an impact on meat quality. One feed that can be used as a substitute feed is tofu dregs, because it contains crude protein, fat, crude fiber, and BETN. The peanut content per 100 grams contains protein, fat, carbohydrates, water, ash, and of fiber, making it an excellent source of protein. The aim of this research was to determine the effect of providing additional feed with tofu dregs and green bean flour on the chemical quality of meat from 35 day old broiler chickens. This research used a Completely Randomized Design (CRD) method with 4 treatments and 5 replications. The treatment consisted of P0 (treatment feed without additional feed); P1 (90% commercial feed, 5% tofu dregs, and 5% green bean flour); P2 (80% commercial feed, 10% tofu dregs, and 10% green bean flour); P3 (70% commercial feed, 15% tofu dregs, and 15% green bean flour). Data analysis used analysis of variance (one way ANOVA) and continued with the Duncan test. The results of the research showed that supplementary feeding with tofu dregs and green bean flour had a significant effect on the water content, fat content and protein content of broiler chicken meat. Providing the best feed composition to produce quality broiler chicken meat is a commercial feed composition of 80%, additional feed 10% each.

Abstract

The floodplain river in Riau is inhabited by various types of vertebrate animals including fish from the genus Ompok. The rapid development of species in the Ompok genus can cause ambiguity in species identity due to inaccurate identification processes. This research aims to analyze the molecular characteristics of two types of selais fish, namely danau selais fish (O. hypophthalmus) and kaporeh selais fish (O. eugeneiatus) from Riau based on 12S rRNA sequences. Methods included sampling of fishes from the Kampar, Tapung and Indragiri Rivers, the total DNA isolation, PCR, electrophoresis, sequencing and data analysis. In this study, the 12S rRNA DNA sequence of the selais fish studied was 939 bp in size. The sequences consisted of 803 bp of conserved sites (86.15%), 127 bp of variable sites (13.52%), 53 bp of parsimony sites (5.64%) and 73 bp of singleton sites (18.57%), with the composition of Adenine 31.7 %, Cytosine 26.9%, Thymine 20.9% and Guanine 20.4%. The average genetic distance between the two species was ±0.034, with the lowest genetic distance identified in the species O. hypophthalmus and O. eugeneiatus from the Indragiri River with a value of ±0.032, while the farthest genetic distance was identified in the species O. eugeneiatus from the Kampar River and the species C. gariepinus (Out group) with a value of ±0.092. Transition substitution (19.50%) occurs more frequently than transversion (10.94%). Phylogenetic reconstruction showed that the two species can be separated into distinct groups based on 12S rRNA sequences.

Abstract

Broiler chickens are good genetic quality as seen from their fairly fast growth. An intensive and controlled cage system can be found in the closed house cage system. Based on the research, the average weight of harvested chickens is not uneven, possibly unequal distribution of fresh air entering through the inlet. This research aims to determine the effect of maintenance distance from the cooling pad on the average body weight growth of broiler chickens kept in closed house cages with a size of 98 X 14 m. as many as 16,000 broiler chickens of the CP 207 strain are randomly allocated into 4 groups or flocks. The distance of flocks 1, 2, 3 and 4 from the cooling pad is 0 -24.5, 24.6 - 49.5 and 49.6 - 73.5, and 73.6 - 98m respectively. The results showed a marked difference (P<0.05) in final body weight. The highest body weight was obtained at the closest distance to the cooling pad and the lowest weight was obtained in the chicken that was in the flock farthest from the cooolig pad. It was concluded that the chicken's body weight is lower the farther the flock is from the cooling pad.

Abstract

The Kepel plant (Stelechocarpus burahol) has garnered research interest due to its diverse secondary metabolites like alkaloids, flavonoids, polyphenols, saponins, triterpenoids, and quinones, thought to impact fertility. This research aims to determine the effect of kepel fruit extract on the number of spermatogenic cells in mice (Mus musculus), consisting of spermatogonia cells, spermatocyte cells, and spermatid cells. Employing a Posttest-Only Control Design, Kepel extraction used 95% ethanol via maceration. 25 mice were divided into groups: positive control, negative control, groups I, II, and III exposed to 50, 100, and 150 mg/kgBW Kepel extract for 36 days. Randomized group design determined sample selection, assessing seminiferous tubules via four fields of vision. Statistical analysis involved one-way ANOVA (5% significance) and LSD test for disparities. Data were analyzed using SPSS 25. ANOVA revealed no significant difference (p > 0.05) in mean spermatogonia and spermatocyte cell counts between control and treatment groups (I, II, III). However, groups I, II, and III exhibited significant spermatid cell reduction. In conclusion, Kepel fruit extract at 50 mg/kgBW, 100 mg/kgBW, and 150 mg/kgBW could lower spermatid cell count, indicating potential as an antifertility agent.

Abstract

Anthropogenic activities in Nypa palm (Nypa fructicans) forests directly leave a lot of residual nipa fronds, which take longer to decompose. The decomposition process involves decomposer organisms, one of which is Arthropods. Nevertheless, information regarding the composition of decomposition fronds is still limited. This study aims to obtain data and information regarding the composition of Arthropods and their relationship to the decomposition period. Arthropod sampling was carried out by hand collecting methods at 15, 25, 35, and 45 days after placement. The laying of the nipa palm fronds was determined randomly with a vertical position at 20 cm above the ground surface. Arthropod eggs, larvae, pupae, and imago samples were sorted and preserved in 70% Alcohol. Arthropod data obtained were analyzed descriptively. The results showed that the composition of Arthropods consisted of the class Crustacea and Insecta, each with one order (2 genera) and six orders (32 genera). The orders Diptera (Psychoda, Eristalinus) and Amphipoda (Allorchestoides) were dominant. The average number of individuals found increases with the decomposition period. The role of different arthropods influences their composition in the decomposition process of the nipa palm fronds. It is necessary to study the composition of microbes in each decomposition period.

Abstract

Coronavirus disease 2019 (COVID-19) is a disease of the respiratory system that spreads rapidly throughout the world with significant mortality and morbidity rate. This literature review aims to provide related information, so as to find out how SARS-CoV-2 is transmitted, the latest control, prevention, and treatment strategies. We searched from online databases and used review articles, research, guidelines from professional organizations, such as Ministry of Health Republic of Indonesia. SARS-CoV-2 spreads rapidly through droplets and attacks the respiratory system by binding to the ACE-2 receptor. This virus spreads from symptomatic or asymptomatic people. Diagnostic accuracy can be improved by combining clinical evidence with results from CT-scans and RT-PCR. Management for COVID-19 patients is carried out based on severity. Understanding pathogenesis can help determine the next step in treatment and prevention of COVID-19.

Abstract

One source of nutrients that influences how a plant grows and produces is fertilizer. fertilization that is possible with both inorganic and organic fertilizers. The purpose of this study is to ascertain how the development of bok choy is impacted by vermicompost, NPK fertilizer, and their combination. Design using RAL two components with five fertilization levels each, repeated three times, such that the experimental unit employed up to 75 plants. The first factor is the dose of vermicompost organic fertilizer consisting of K 0 = 0  gr (control), K1  = 50 gr, K2 = 100 gr, K3 = 150 gr and K4 = 200 gr. The second factor is the dose of NPK fertilizer (16:16:16) consisting of N 0 = 0 gr (control), N 1 = 0.3 gr, N2 = 0.6 gr, N3 = 0.9 gr and N4  = 1.2 gr. The ANOVA test was used to evaluate the data. The findings revealed that the vermicompost treatment had no appreciable impact on the plant's height, number of leaves, leaf area, wet weight, or dry weight characteristics. The use of NPK fertilizer has a sizable influence on plant properties such as height, leaf count, leaf area, wet weight, and dry weight. Vermicompost and NPK fertilizer together have a considerable influence on the metrics of plant height, leaf count, wet weight, and dry weight.
