Abstract

The presence of birds in Gili Meno has a positive impact on environmental aspects as birds serve as bioindicators of environmental quality, pest controllers, and aid in pollination processes. Based on research conducted in 2010, 2011, 2012, and 2015, there has been an increase in bird populations in the Gili Meno area, particularly birds from the Ardeidae family. With rapid development currently underway, it is suspected to affect the presence of birds in Gili Meno, necessitating monitoring of bird diversity and conservation status in the area. This study aims to assess the diversity and conservation status of birds in the Gili Meno area. The research was conducted on Gili Meno from May to June 2022. Data collection utilized snowball sampling for interviews and transect methods combined with point counts. Observational data were analyzed using the Shannon-Wiener diversity index. The results indicate a total of 29 bird species found in the Gili Meno area, belonging to 22 families, with a diversity index of 2.8. The conservation status of most birds (97%) in the Gili Meno area is categorized as "least concern" according to IUCN criteria and classified as "unprotected" species under P.106/MENLHK/Setjen/Kum.1/12/2018. Acridotheres javanicus is listed as vulnerable by IUCN, while Thallaseus bergii is protected under P.106/MENLHK/Setjen/Kum.1/12/2018.

Abstract

Betta fish is a freshwater ornamental fish with a unique body shape and the brightness of its color is one of the attractions among its fans. The increase in color intensity and growth in betta fish is greatly influenced by the nutrient content in the feed and genetics. Adding Spirulina platensis flour to feed is expected to increase feed nutrients such as beta carotene, which is known to increase the intensity of color and growth of betta fish. This study aims to prove whether adding Spirulina platensis flour to feed can increase the intensity of color and growth of betta fish. The experimental research used a Complete Random Design (RAL) with 4 treatments and 3 replicates, namely P0 (0%), P1 (3%), P2 (5%), P3 (7%) for 3 months. The parameters measured were color intensity and growth. Test F to determine the effect of treatment on parameters, if there is a real influence, the Duncan test is carried out The test fish in the study is a one-month-old, blue, and male betta fish seed. The results showed that the addition of Spirulina platensis flour to P1 treatment feed (3%) experienced the highest increase in color intensity (P<0.05) followed by P2 treatment (5%), then P3 treatment (7%) and finally P0 treatment (0%). The P1 treatment (3%) was shown to be optimal in increasing the intensity of the color of betta fish but was not followed by an increase in growth.

Abstract

There is an endemic animal in West Nusa Tenggara namely the Timor Deer (Cervus timorensis). However, the population has decreased over time, and the Timor deer species is categorized as an endangered species by the IUCN. The decline of the Timor Deer population in Lombok island is due to lose its natural habitat in the forest. And one of the causes that is deforestation. Deforestation is the conversion of forests into land for use, such as clearing land for agriculture and plantations. Therefore, to maintain the Timor Deer population in Lombok island, it is also important to balance it with providing knowledge about conservation to the community through conservation education. This research aims to analyze the relationship between the deforestation phenomenon and the decline of the Timor Deer population and the importance of conservation education for the community in Lombok island, West Nusa Tenggara. Using a systematic literature review method by collecting data and literature from several journals. The results show that there is a relationship between the deforestation phenomenon and the decline of the Timor Deer population in Lombok and the importance of conservation education to the community to increase public awareness to protect endemic animals.

Abstract

Waste is an environmental problem caused by the activities of living things. The synthetic waste group or what is often found in the form of plastic and the like is a group of waste that is very difficult to degrade. This can be overcome by using lipolytic bacteria. This research aims to analyze lipolytic bacteria which can be used to biodegrade plastic waste in the Bonoloyo TPU, Makam Haji TPS, and the Bengawan Solo river flow. This research uses quantitative descriptive methods. Screening for lipolytic bacteria degrading polystyrene (PS) showed that the highest population of lipolytic bacteria isolated from public burial places of 15.6 x 104. Meanwhile, lipolytic screening with the highest average clear zone formed was 0.641 cm which came from TPS 1, then average -The highest average lipolytic index came from SBS 2 with a figure of 1.6525 cm, the largest average colony diameter came from TPS 1 soil samples at 0.45 cm. The degradative nature of bacteria on plastic above shows that the Bengawan Solo river has microbes with the highest ability compared to microbes from TPS and TPU, namely 22.42%. The degradation between TPU, SBS, and TPS is significantly the same. PS degradation in Bonoloyo TPU shows significant physical changes.

Abstract

This research aims to determine the physical and chemical quality of dug well water in the area where shrimp paste (terasi) is produced at Jor Hamlet, Jor Village, Jerowaru Subdistrict, East Lombok Regency. The research method used was experimental, focusing on parameters such as temperature, pH, TDS, and hardness based on the Indonesian National Standard (SNI) guidelines. Three sampling points of community dug well water were selected with sampling conducted twice, considering the sampling points based on the distance between the dug wells and the shrimp paste production area being less than 10 meters, and due to the absence of proper wastewater disposal systems at the shrimp paste production site. From the results of the examination of the physical and chemical water quality around the shrimp paste production area in Jor Hamlet, Jor Village, Jerowaru Subdistrict, East Lombok Regency, it was found that several parameters met the requirements according to the Indonesian Ministry of Health Regulation Number 32 of 2017 concerning the Standard of Environmental Health Quality and Health Requirements for Hygiene, Swimming Pools, Solus Per Aqua, and Public Bathing. Parameters such as temperature, pH, and TDS met the standards. However, the examination revealed that the hardness of the dug well water exceeded the standard in one out of the three sampling points. Specifically, samples A and B met the standard for hardness, whereas sample C did not meet the standard because it exceeded the established quality standard of 500 mg/l.

Abstract

Bileh fish (Rasbora sp.) is a fish that lives in freshwater and can be found in the waters of Ie Sayang West Woyla West Aceh District. Excessive exploration has caused the population of bileh fish in nature to decrease and be limited. The first step that needs to be done in aquatic resource management is to identify the type of bileh fish to adopt its cultivation techniques. Fish identification can be done morphologically or molecularly. Morphological identification refers to morphometric studies. This study aims to identify bileh fish species from Ie Sayang waters based on morphometric characteristics. The bileh fish was obtained from community catches in September-November 2023. Morphological identification was done by visualizing and measuring morphometric characters. Data were analyzed descriptively, and the relationship between morphometric characters was analyzed by linear regression. The morphology of bileh fish has a fusiform body shape, terminal mouth type, forked caudal fin, and linea lateralis visible from the operculum to the caudal part. Total length (TL) ranged from 36.94-65.78 mm and standard length (SL) 29.01-52.49 mm. The length-weight correlation of allometric fish was negative. TL characters were closely correlated with SL, HL, DFD, ED, CPD, and VFL.

Abstract

Efforts to cultivate snakehead fish (Chanidae) still experience many problems, especially the availability of high-quality fry. To improve the quality of fry, improving the quality of broodstock is important. Genetic factors play an important role in the selection and breeding of snakehead fish parents. Therefore, it is necessary to explore sources of superior parents with good genetic characteristics. To achieve this goal requires studies from various fields such as ecology, biology, and genetics. Genetic studies can be started by examining the identity and relationships of snakehead fish from Merauke, as a first step in finding a source of germplasm that has high diversity. The aim of this research is to analyze the cytochrome oxidase subunit 1 (COI) gene fragment of snakehead fish from Merauke, Papua. DNA isolation was carried out using the Promega kit with standard protocols, amplification of the COI gene with primers F2 and R2 with the Go Taq Green amplification kit. A total of 653 base pairs of the COI gene fragment were obtained from the sequencing process, with a nucleotide composition of T (29.9%), C (28.8%), A (24.0%), G (17.3%). BLAST results on the NCBI database show that this sequence has 100% similarity to the Channa striata sequence from Papua with sequence ID OQ405388.1. This shows that the identification results of the snakehead fish from Merauke are Channa striata. Phylogenetic tree analysis also showed consistent results, namely the formation of a clade that was the same as the Channa striata fish group derived from GenBank data.
