Abstract

Coral reef fish is one of the main components making up the ecosystem of coral reefs. There is a strong mutual dependence between reef-forming corals and fish that inhabit coral reefs. Various fish species use coral as a food source and habitat. This article describes the impact of coral bleaching on the diversity, density, and biomass of coral reef fish in the waters of Sekotong Bay, West Lombok. Underwater visual census (UVC) methods are used to obtain data on species, the number of individuals per species, and fish size at transect length 70 meters and width 5 meters. Simple linear regression analysis that is used to assess the impact of coral bleaching on the condition of coral reef fish shows that coral bleaching affects the diversity and density of reef fish. This analysis also showed that coral bleaching affected herbivorous fish biomass but not carnivorous fish. This study concludes that the degradation of coral fish in the Sekotong Bay of West Lombok occurs due to various factors, especially the declining health conditions of coral reefs

Abstract

This study aims to explain the phenomenon of motion in hamsters moving in a rolling wheel. Motion is one of the materials taught at the 7th-grade junior high school. The study can be used in learning with the practicum method, namely animal motion. Hamster (Cricetinae) motion is analyzed using a video tracker analysis application with a javascript program. This study used a direct experiment using a hamster using four reference points, namely the forelegs, head, middle body, and hind legs. The results of data analysis from the tracker application were processed using the Microsoft Excel program to obtain a graph of changes in the position and velocity of the hamster. Hamster motion on the rolling wheel is a type of translational motion, namely uniform linear motion.  Changes in the hamster's position indicate motion on a horizontal line. The velocity obtained in the tracker application is more accurate than manual calculations.

Abstract

Pulau Ay is an island located west of the Banda Islands, Central Maluku Regency, Maluku Province. Nearly 85% of the soil structure on Ay Island is filled with coral reefs, so it is very difficult to get clean water and the people of Ay Island only rely on rainwater to get clean water. The purpose of this research is to innovate to purify seawater into drinking water in the village of Pulau Ay and test the quality of the water produced. This research was conducted by designing a seawater purification device called Tampayang (Ay Island's drinking water station) consisting of a water storage barrel, a simple filter, a seawater distillation apparatus and a reverse osmosis (RO) membrane machine. The water produced from the purification of seawater is then analyzed in a laboratory according to Indonesian national standard and the regulation of the Minister of Health of 2010 concerning drinking water quality requirements. The results showed that the Tampayang tool produces 2 types of water, namely clean water and drinking water. After being tested both types of water meet the water quality requirements for consumption based on physical, chemical and biological parameters. The clean water and drinking water produced can be useful and consumed by the people of Ay Island as a solution to seawater utilization

Abstract

Breast cancer is among the diseases with the highest mortality rate in women in the world. The triple negative cancer subtype with aggressiveness and metastatic ability causes the sufferer to be difficult to treat. Targeted treatment efforts of natural ingredients such as limonene and its derivatives are more profitable due to their easy excretion process. Screening the activity of compounds through docking specifically provides convenience in the synthesis process in the laboratory. Limonene compounds and their derivatives will be interpreted against the enzymes MMP-2 (PDB ID: 3AYU), MMP-9 (PDB ID: 4H1Q) and Cyclin A2 (PDB ID: 2V22) involved in the cellular function of triple-negative breast cancer using PyRx 9.0 software. The docking results showed that the limonelyl salicylate compound provided the best binding affinity value against the enzymes MMP-2, MMP-9, and Cyclin A2 with successive values of -7.7, -8.8, and -6.7 kcal/mol.
