Abstract

A healthy coral reef ecosystem will be used as a place for spawning and foraging for various marine biota. With high primary productivity and diversity, coral reef ecosystems will become ecosystem that has a lot of useful potential. Abang Island and Abang Besar Island, Batam, are two of the locations with a good coral reef ecosystem. Unfortunately, these ecosystems have been disturbed by marine tourism activities. Therefore, observations are needed to determine the condition of coral reefs in Abang and Abang Besar Islands. Coral Point Count with Excel Extensions (CPCe) is a software that helps to identify and know the condition of coral reefs in an area. Data processing in this CPCe program will generate data in the form of Excel files that show the results of identification analysis. Based on data processing using the CPCe program, the results of the percentage of coral cover at the six stations varied (32.67 - 51.33%) from the bad to good categories. At Station 1 or BTMC01, the highest coral cover is 51.33% and the lowest is at Station 2 or BTMC02 at 32.67%. The condition of coral reefs with good categories is only found in BTMC01, the rest has the condition of coral reefs in the medium category. The percentage of coral cover obtained is a combination of Acropora and Non-Acropora coral group species. Good or bad coral cover in an area is strongly influenced by anthropogenic activities.

Abstract

Indonesia is known as one of the world's marine biodiversity centers with its rich coral reefs. Coral growth depends on environmental conditions, which in reality do not always remain due to disruptions originating from nature or human activities. The growth of coral reefs in a sea water is strongly influenced by the quality of its waters such as chemical oceanographic factors namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The waters of Damas Beach are located in Karanggandu Village, Watulimo District. The purpose of this study was to determine the condition of coral reefs in Damas Waters, to determine the effect of water quality on artificial reefs in chemistry in Damas Waters and to determine the relationship of quality parameters of chemical waters with artificial coral reefs in Damas Waters, Trenggalek, East Java. The sampling method is done by purposive random sampling that is determining the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results obtained that in all stations found good water conditions for the life of coral reefs, and also the analysis of the relationship of each parameter and coral reefs influence each other.

Abstract

Damage to coral reefs is generally caused by destructive fishing activities, they were the usega of explosives, cyanide toxic materials, coral mining for building materials, anchor boat anchors, and the results of sedimentation. Efforts to speed up the process of coral reef recovery, several methods of rehabilitation that can be done include coral transplantation and sinking of artificial reefs. The artificial reef is an alternative to reduce the pressure caused by fishing and destruction of natural coral reefs through the creation of new productive fishing grounds. The purpose of this study was to determine the relationship of water parameters (physical oceanography) for biota around artificial reefs based on Geographic Information Systems. The results of identification of oceanographic parameters in the waters of Damas Beach, Trenggalek Regency consist of: (a). depths range from 0-45 meters, (b). brightness ranges from 2 - 6 meters, (c). water temperature ranges from 25.18-29.59ºC, (d). water turbidity ranges from 0.3-4.32 NTU, (e). type of substrate base waters of Damas Beach fine black sand, (f). current speed ranges from 0.1-0.4 m/s, (h). the average wave height of Damas Beach in the morning, afternoon and evening is 5.6 cm, 8.14 cm and 6.2 cm, (i). the total suspended solid waters of Damas Beach range from 35-351 mg/L. The physical oceanographic parameters are still safe for the growth and development of biota in the waters of Damas Beach, Trenggalek Regency.

Abstract

Total suspended solids (TSS) are sediment material that floats in the water column that moves without touching the water bed, influenced by input from land, river flow, and water oceanography factors. TSS is closely related to sedimentation, which can harm aquatic ecosystems, especially coral reefs. This research was conducted using TSS data as well as flow data for each season (May, June, October 2019, February and March 2020) to know the distribution of suspended solids concentration, knowing the dynamics of changes in TSS concentrations on Damas Beach by season, and to determine the relationship TSS with the growth of coral reefs at Damas Beach. TSS levels in Damas waters are quite high, which can be indicated by the turbid waters. TSS levels in March 2020 showed dominating results with a range of 37.8–72.6 mg/L and an increase in the range of 72.7-145 mg/L. The highest distribution of TSS on Damas Beach is found in the Rainy season.

Abstract

Teluk Prigi mempunyai potensi perikanan laut dengan jumlah produksi perikanan tangkap mencapai 4.108,57 ton/tahun. Potensi perikanan teluk Prigi ini diimbangi juga oleh pergerakan nutrient yang disebabkan oleh pergerakan arus. Pergerakan nutrient di dalam perairan tentu saja tidak lepas dari faktor arus permukaan suatu perairan. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana pola persebaran suhu yang mempengaruhi pergerakan arus yang ada di Teluk Prigi dari kedalaman 1 meter hingga kedalaman 5 meter. Pergerakan arus ini akan menentukan bagaimana persebaran kualitas air yang ada di perairan Teluk Prigi. Kondisi arus di perairan teluk prigi pada umumnya bergerak menuju ke arah timur laut dengan kecepatan ±0,8-1,4 km/jam. Suhu perairan teluk prigi di permukaan laut dan pada kedalaman 1 meter pada kisaran 28 hingga 29oC. Adanya perbedaan suhu akan menyebabkan adanya perbedaan tekanan, sehingga menyebabkan munculnya angin. Keberadaan angin menyebabkan massa air berpindah dari suatu tempat ke tempat yang lain. Persebaran klorofil-a di wilayah Teluk Prigi pada umumnya berada di perairan yang relatif dangkal, yaitu 2,13 hingga 3,66 mg/m3, dimana ini menunjukkan adanya potensi perikanan yang baik guna mendukung ketahanan wilayah pesisir, terutama dalam memenuhi kebutuhan pangan dan finansial dari keluarga Nelayan di Teluk Prigi.
