Abstract

Cucumber (Cucumis sativus L.) has a fairly good nutritional content and is in great demand by the public. Cucumber production in NTT continues to increase, but it is still low when compared to national production data. One of the efforts made is to use liquid organic fertilizers that are cheap and easy to get around us because they come from natural ingredients, namely plant residues or animal remains. Lamtoro leaf extract (Leucaena leucocephala, Ssp) is an organic fertilizer made from plants that is environmentally friendly. In addition to the fertilization factor, pruning activities are also needed to increase the weight of cucumber production. Pruning is a common cultivation action to limit excessive vegetative growth in plants so that nutrients or nutrients can be absorbed by the parts of plants that need them optimally. These nutrients can be provided by lamtoro leaf extract, then pruning is also carried out in order to reduce photosynthetic competition in order to increase cucumber production. Based on this description, it is felt that it is necessary to conduct research on the effect of giving concentration of lamptoro leaf extract and pruning on cucumber plant production. The purpose of this study was to determine the interaction of giving lamptoro leaf extract concentration and pruning on cucumber plant yields. This research was conducted from May to June 2022. This study was arranged using a randomized block design (RBD) in a factorial pattern with two factors. The first factor was the application of lamtoro leaf extract fertilizer consisting of four levels, namely: L0: control (without lamtoro leaf extract), L1: 400 cc of lamtoro leaf extract liter of water-1 plot-1, L2: 450 cc of lamtoro leaf extract liter of water-1 plot-1, L3: 500 cc of lamtoro leaf extract liter of water-1 plot-1. The second factor is pruning (P) consisting of three treatment levels, namely: P0: No pruning, P1: Pruning one leaf and one branch on segments 6–12, P2: Pruning two leaves and two branches on segments 6–12. The results obtained: administration of 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on segments 6–12 of cucumber plants had a very significant effect on cucumber plant yields, concentration of 500 cc of lamtor leaf extract lamtoro liter of water-1 plot-1 and pruning two leaves and two branches on 6–12 plant nodes produced the best growth and yield of cucumber plants, the interaction between lamtor leaf extract and pruning resulted in plant length 79.33, fruit weight 284.83 g, fruit length 30 cm and fruit diameter of 4.48 cm. Recommendation: for cucumber cultivation, it is better to use POC of lamtor leaf extract 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on internodes 6-12 plants. There needs to be further research on the use of POC concentrations of lamtoro leaf extract with higher concentrations to reduce the use of inorganic fertilizers.

Abstract

Closed house waste which has so far been considered a contributor to environmental pollution if processed professionally, can be reused as a component of non-ruminant rations. The purpose of this study is to determine the production (potential, quantity, and quality) of broiler farm waste that is maintained in a closed house system. The cost of production of non-ruminant livestock (pig) 70-80% is still occupied by the cost of feed. The price of commercial concentrate is relatively expensive, which is a reason to look for alternative feed sources. The discovery of potential closed house chicken farm waste and innovative products as a source of protein in rations for non-ruminant (pig-poultry) is expected to the feed problem. Innovative product protein concentrate chicken farm waste of closed house (WCH) system that is cheap and competitive is produced through three stages of research: identify the type and availability of waste, its nutrient content, formulate various protein concentrate formulas, and small-scale tests on pigs with metabolic cage to determine metabolized energy content and digestibility. The results showed that the type of closed house waste (WCH) that has the potential as alternative animal feed is the waste of dead-refused chickens, and litter mixed with scattered feed. Production data in 4 periods of rearing, obtained the number of dead and rejected chickens weighing 850.7 kg (212.7 kg/period), and litter weight of 4000 kg (1000kg/period). Nutrient content of flour mixed with closed house waste (WCH), protein: 36.58%, crude fat: 4.42%, gross energy Kcal/gram. aboratory test of WCH was negative for Eschericia colli and Salmonella shigella, Coliform < 3.0 CFU/g, mold 200 CFU/g. The conclusion of this study is that the waste from closed house (LCH) broiler farms has the potential as a source of protein in alternative feeds for rumonants (chicken and pig).

Abstract

Bioinformatics has become a buzzword in today's world of science. About twenty or thirty years ago, people saw biology and computer science as two completely different fields. However, at present, it seems that a new bridge has been built that connects these two fields, and this new field is called bioinformatics. Bioinformatics is an challenging and exciting new multidisciplinary field. This field combines methods of statistics, mathematics, computer science and information technology to solve problems based on biological data. Advances in experimental technology have generated large amounts of data. Therefore, managing and extracting useful information from these sources is essential if we are to discover new knowledge to advance our understanding of life. In this article, we try to discuss what is bioinformatics?, The basic knowledge needed to understand bionformatics and the reasons that are very important for biologists to learn and apply bioinformatics. In addition, we also discuss an introduction to biological terminology that will be widely used in the field of bioinformatics. We are confident that this review will provide valuable insights and serve as a starting point for researchers to become acquainted with and study bioinformatics.

Abstract

Horses are livestock which are used as a source of meat for the people in Jeneponto Regency. Horse rearing is still traditional where horses are kept in a semi-intensive system and consume local forages. Slaughtering of horses in this area was carried out at slaughterhouses that produce carcasses as a product. Horses slaughtered, both stallions and mares, range in age from 3-7 years. Based on this background, it is necessary to conduct research because it is not yet known how horse carcasses are produced from this feeding system when viewed from sex differences. The research was carried out from August to September 2022 at slaughterhouses spread across the Jeneponto Regency, South Sulawesi. The types of horses slaughtered and examined for their carcasses were Sumba horses, Sulawesi/Bugis horses. Carcass weight data were tested using one-way ANOVA and H-test in SPSS 2020. The results showed that male carcass weight was higher than female carcass weight. The male horse carcass weight was 120.20 ± 6.38 kilograms, while the female body weight was 107.4 ± 6.19 kilograms. The correlation between sex and carcass weight in horses fed local feed showed a significant relationship (p<0.05). Based on the results of the study, it can be concluded that there is a significant difference in carcass weight between stallions and mares by feeding local forages and there was a correlation between the sex of horses fed with local forage and the weight of the carcass produced.

Abstract

Mangroves have an important role in mitigation and a significant contribution to the wealth of macrofauna. The success of mangrove management has significantly affected the diversity of macrofauna which are associated biota. The research objectives were to investigate the composition of mangroves and mollusc communities, the ecological conditions of the waters, and evidence of mangrove ecosystem services in mitigation. The research data sources are faunal, ecological, and social data. The research method uses purposive sampling and data analysis using descriptive statistics. The results showed that 7 mangrove species were found in the Cemare mangrove area. Avicennia marina, Bruguiera gymnorriza, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, and Sonnetaria alba. The dominant mangroves were Rhizopora stylosa (201 ind/Ha) and Rhizopora apiculata (146 ind/Ha). Meanwhile, the highest abundance of mollusc species was obtained by Cerithidea cingulate (38.94%) and Nerita undata (29.20%) from the gastropod class, while from the Bivalvia class, Anadara grandis (36.07%) and Anadara granosa (19.67%) were found). The condition of the aquatic environment at the research site is still within the tolerance range required for the growth and development of mollusk species. Furthermore, the majority of respondents know or are aware that mangroves have an ecological function (habitat/habitat for animals), an economic function (a livelihood location), a physical mitigation function (abrasion resistance), a non-physical mitigation function (reducing environmental heat) Good category. These results indicate that efforts need to be made to increase mangrove revegetation, given its significant benefits in mitigation.
