Abstract

Coral reefs are the most productive and diverse ecosystems. This study aims to determine the condition of coral reefs, using the Line Intercept Transect (LIT) method. Data were collected in October 2018. The results of the study found 18 categories of benthic growth forms crossed by the transect line, where the biotic component was 63.02% and the abiotic component was 36.98%. The biotic component consists of 26.6% hard corals, 0.44% dead corals, 3.54% algae, and 32.44% other fauna while the abiotic component is only dominated by 36.98% sand. Coral cover of 26.6% shows the condition of coral reefs is in a fair condition. The cause of the low percentage of coral cover caused by human activity (anthropogenic impact).Keywords: Coral reef; Line Intercept Transect; Amahusu Village

Abstract

Coral fish is one of the organisms associated with the most coral reefs and is a large organism that can be found in all coral reef habitats. This study aims to determine the diversity of reef fish, community structure, and abundance of reef fish in the Depapre Bay Waters, Jayapura Regency. This research was conducted from September to October 2017 in Serebo and Kampung Tua waters. The method used is the Underwater Visual Census method at a depth of 3 to 5 m with a transect length of 75 m and an observation width of 5 m. A total of 69 species of reef fish found at the study site consisted of 16 reef fish families. The number of reef fish species at Serebo and Kampung Tua stations is 47 species and 38 species, respectively. The diversity index of reef fish ranged from 2.8264 to 2.9615 which was classified in the medium category. The uniformity index ranges from 0.7341 to 0.8142, which indicates that the community is relatively stable. The dominance index at Serebo Station is classified as high (1.00) which indicates that there are certain species (Pomacentrus mollucensis) that dominate, while at Kampung Tua station there are no specific species that dominate with a dominance index value of 0.3256. The abundance of reef fish at Serebo station was higher at 1.8347 ind/m2 than the abundance of reef fish at Kampung Tua station which was 0.5973 ind/m2. The highest abundance of reef fish species at Serebo station was Pomacentrus mollucensis (0.3647 ind/m2), while at Kampung Tua station was Ctenochaetus striatus (0.1333 ind/m2).Keywords: Reef fish; Coral reef; Underwater Visual Census; Community structure; Depapre Bay

Abstract

Cellulose is included in the main polysaccharide group that is widely available in nature. Cellulose is a straight-chain glucose polymer that is bound by β-1,4 glucoside bonds. Cellulase is an enzyme complex consisting of several enzymes that work in stages or together in breaking down cellulose into glucose, by hydrolyzing the β-1,4 glucoside bond in cellulose. Cellulase enzymes have been used in various industries. Industrial applications require enzymes that are stable at high temperatures. Various types of thermostable enzymes can be isolated from thermophilic bacteria, cellulase enzymes are no exception. This study aims to isolate and identify thermophilic bacteria that produce cellulase enzymes from Sila hot springs. The results of isolation and screening of cellulase-producing bacteria from hot water samples obtained by 7 isolates that have the ability to degrade cellulose can produce clear zones on LB-CMC agar selective medium, but CR2 isolates showed the largest zone of 1.5 cm. CR2 isolates were Gram-positive bacteria and were identified as having close relations with Bacillus aryabhattai strain B8W22 using the 16S rRNA method.Keywords: Cellulose; Cellulose enzyme; Thermostable enzyme; Thermophilic bacteria

Abstract

This study aims to determine the diversity, abundance, and economic value of target fish in the mangrove ecosystem of Demta Bay, Jayapura Regency, Papua Province, Indonesia. This research was conducted from August 2019 to January 2020. The research method used was the field observation method, the purposive sampling method, and the method of interviewing the community. The target fish diversity index value at all stations is 1.92. Based on the diversity index criteria it can be seen that the diversity of target fish in the mangrove ecosystem of Demta Bay is classified as moderate. The results of data analysis obtained the value of abundance from all stations is 1086.67. The target fish diversity value and the target fish abundance value indicate that the number of target fish groups in the waters of Demta Bay is quite good. There are several species of target fish that have high prices, namely Ephinephelus quoyanus with the local name Uwga and Cephalopholis microprion with the local name Padamuw. Besides, there are also several species of target fish that have a fairly low selling price, including Pristiapogon fraenatus (Dakai Tipir), Nematolosa come (Pylair), Lactarius lactarius (Lema), Leighnathus equluus (Awara), Valamugil buchanani (Amakai) and Upeneus vittatus (Marep).Keywords: Diversity index; Economic value; Fish target; Demta Bay

Abstract

The waters of Humbolt Bay in Jayapura City have a diversity of habitats in shallow water. The purpose of this study is to map the shallow water habitat in the waters of Humbolt Bay, Jayapura City using Sentinel-2A satellite imagery. This research was conducted from April to May 2019 in several parts of Humbolt Bay, including Kosong Island, Kayupulo Island, and along the coast from Hamadi to Weref. Mapping of shallow water habitat using the supervised classification method with Lyzenga algorithm transformation. The accuracy of the classification results is done by using the confusion matrix method to compare the sample points in the field with the results of the classification of satellite images. Sentinel-2A satellite image data processing results obtained shallow water habitat including live coral, seagrass, dead coral, and sand with an estimated area of about 269.8 Ha, 148.9 Ha, 156.1 Ha, and 87.6 Ha. The results of the accuracy-test analysis showed that the mapping accuracy was 73.77% of the 61 validation points used for the accuracy test.Keywords: Bottom habitat; Sentinel-2A; Supervised; Lyzenga algorithm; Humbolt Bay
