Abstract

Bacteria are agents that can be used widely and are genetically easy to manipulate and reproduce. Many studies related to the isolation and identification of bacterial isolates from Indonesia have been carried out for various purposes. This research is still ongoing and has never been informed about the abundance of data from previous studies. The purpose of this study is to provide an overview of research topic trends related to the isolation and identification of bacterial isolates from Indonesia. The method used in this review is by setting inclusion and exclusion criteria and selecting a random sample of articles for analysis. The results of a review of research trends in isolation and identification of bacterial isolates from Indonesia showed four main topics discussed, namely the topics of food processing, agriculture, health, and bioremediation. Analysis of 41 articles shows that the most common discussion is the exploration of Lactate Origin-producing bacteria, the role of improving food quality. Furthermore, it was identified that the most isolated bacterial isolates came from food and plants, with 14 publications from a total of 41 articles. It can be concluded that exploratory research on Lactic Acid Bacteria for improving the quality of food products is currently the most studied topic by researchers in Indonesia.

Abstract

The Sumatran elephant (Elephas maximus sumatranus) is a large mammal protected species and categorized as endangered according to the IUCN Red List. Habitat management includes control and regulation forest vegetation, open areas, water sources, salting sites, and resting areas for good animal welfare. The Seblat Elephant Training Center (SETC) is a conservation area to protect the Sumatran Elephant from extinction and is an ecotourism destination. This study aimed to analyze the welfare level and management of the Sumatran elephant in the SETC. This research used structured interview method to determine the indicators of the animal welfare level. Calculation of feed productivity and secondary data collection were used to improve the welfare level of the Sumatran Elephant. The research result stated that the welfare level of Sumatran elephant was classified as excellent (the implementation achievement value is 74.3%). In addition, the development of observations suggests that freedom from environmental discomfort needs to be improved by providing quarantine cages and reproductive cages to support natural behavior. Environmental conditions also support the welfare level of the Sumatran elephant.  In conclusion, this facility is properly conducive to the welfare of Sumatran elephants.

Abstract

Salak is typical Indonesian fruit commonly found in tropical countries. This fruit can fill global fruit market via exports to various countries.  One of the varieties is "salak madu" ("honey salak"), whose scientific name is (Salacca edulis Reinw), which has higher economic value than "salak pondoh super". Some of the characteristics of honey salak are thick flesh, high water content, and sweet taste. Due to its high water content, honey salak rots quickly, resulting in useless waste and causing unfavorable smell. As such, utilization of overripe salak fruit (ripe close to rotten) can be done with implementation of biotechnological approach using Acetobacter xylinum to make nata. This study is aimed at utilizing overripe honey salak (ripe close to rotten) by processing it into Nata de salaca and identifying the factors affecting the production of Nata de salaca. The study used systematic review method by reviewing and examining previously published journal articles. The results of this study suggest that overripe salak can be utilized to make Nata de Salaca with the help of Acetobacter xylinum. Based on ratio of salak substrate to water, a good Nata has the ratio of 1 : 4. 1. Whereas, based on the factor of sprout extract additive material, it is  3%. Dan Whereas based on optimum duration of fermentation, it is 10 minutes.

Abstract

The application of botanical pesticide is a positive long term approach to control S. frugiperda. Shallot leaves contain acetogenin compound, hence it has the potential to become botanical pesticide. This study is aimed at finding out the effects of ethanolic extract of shallot leaves on S. frugiperda larvae in vitro. Extract is prepared using maceration method with ethanol solvent. The method of treatment is Leaf Dipping. The study applies Completely Randomized Design with concentration of shallot leaf extract as treatment at 0 ppm, 250 ppm, 500 ppm, 750 ppm dan 1000 ppm. Each treatment consists of four repetitions. Examination is conducted for 24 hours. Examination parameter is mortality of larvae and LC50. Data are analyzed with One Way ANOVA (proceeded with LSD) and Probit analysis. The results suggest that shallot leaf extract at the concentration of 1000 ppm appears to be the most effective on the mortality of larvae. The obtained LC50 value is 263,02 ppm. The study indicates that shallot leaf extract can be applied as an alternative synthetic insecticide to control ini S. frugiperda.

Abstract

The Estuaries of Progo and Opak rivers, being the terminus of all rivers flowing through the Special Region of Yogyakarta, are highly susceptible to pollution which results in decreased water quality. The use of meiofauna as a bioindicator to assess water quality in the estuaries of Progo and Opak rivers has never been made. This study aims to determine the diversity of meiofauna at the estuaries of Progo and Opak rivers. Stations and sampling points are determined using purposive sampling method. Extraction is conducted using water ice treatment method. The meiofauna obtained from the sediment screening are then identified, calculated and analyzed to find out the index values ​​of abundance, dominance, diversity, and evenness. The results showed that the highest meiofauna abundance index was 247,333 ind. m-2 at the estuary of Progo river station 1 at the time of the first pick-up. While the lowest meiofauna abundance was 13,333 ind. m-2 at station 2 of Opak river estuary during the first take. The dominance at the estuaries of Progo and Opak rivers is in the moderate category. The meiofauna diversity in both river estuaries is categorized as low to moderate. Evenness in both estuaries is uneven at several stations. The meiofauna diversity at the estuaries of Progo and Opak rivers is low to moderate, although the water quality still meets the quality standards.
