Abstract

There are several kinds of tourist objects in Jayapura City, one of which is the Hamadi beach tourist attraction. Tourists on Hamadi beach increases anthropogenic activities which can cause the aesthetics of the waters to decrease. Physical and chemical pollution can increase biological pollution, namely the presence of pathogenic bacteria such as coliform bacteria. Tourist beach waters that have been contaminated with Coliform bacteria will have an impact on tourists. The conducted of this study was to determine the density of Coliform bacteria, Nitrate and Phosphate concentrations and the relationship between Coliform bacteria density and Nitrate and Phosphate concentrations. The method used in this study was a survey method with a quantitative descriptive approach, while the data collection technique used a purposive random sampling technique at 3 stations with 3 points at each station. Data analysis used includes analysis of Coliform bacteria density, analysis of water quality based on the quality standard of the relationship between coliform bacteria density and concentrations of nitrate and phosphate using Pearson correlation analysis. The results showed that the average density of bacteria at station I was found to be 494 colonies/100mL, station II was found to be 58 colonies/100mL and station III was found to be 35 colonies/100mL. Nitrate and Phosphate concentrations in the coastal waters of Hamadi tourism were at station I the concentration of nitrate 1.90 mg/L and phosphate 0.045/mg/L. The concentration of nitrate at Station II was 2.4 mg/L and phosphate, which was 0.41, exceeded the water quality standard (0.015). Nitrate and phosphate concentrations at Station III were 4.40 mg/L nitrate and 0.060/mg/L phosphate. Based on the Pearson correlation test, the relationship between the density of Coliform bacteria and the concentration of Nitrate and Phosphate in the waters of the Hamadi tourism beach was found to have an opposite or weak and moderate relationship.

Abstract

Ekosistem terumbu karang merupakan salah satu ekosistem utama di wilayah pesisir dan laut yang memiliki peran yang sangat besar terutama dalam mendukung sektor perikanan dan pariwisata. Perairan pantai Harlen Kampung Tablasupa memiliki ekosistem terumbu karang yang baik dan potensial untuk dimanfaatkan demi peningkatan kesejahteraan masyarakat. Ironisnya, pada beberapa lokasi telah mengalami kerusakan akibat penangkapan ikan yang menggunakan bahan peledak (bom) maupun akar tuba. Oleh karena itu, perlu upaya rehabilitasi yang telah rusak salah satunya dengan transplantasi karang. Transplantasi karang merupakan teknologi memperbanyak koloni dengan memanfaatkan reproduksi aseksual karang secara fragmentasi dari suatu koloni karang. Transplantasi bertujuan untuk mempercepat regenerasi karang yang telah mengalami kerusakan. Metode yang digunakan adalah metode rangka besi yang menyerupai jaring laba-laba sehingga dikenal dengan Metode Spider. Kegiatan ini dilaksanakan oleh Pusat Studi Sumber Daya Kelautan dan Perikanan Universitas Cenderawasih dengan melibatkan beberapa mitra dengan dukungan pendanaan dari PT PLN (Persero) Unit Induk Wilayah Papua dan Papua Barat melalui Program PLN Peduli. Hasil transplantasi menunjukkan bahwa metode Spider sangat berhasil, dimana tingkat kelangsungan hidup mencapai 92%. Tingkat kelangsungan hidup tersebut diduga karena pemilihan lokasi yang tepat dan kemampuan jenis yang ditransplantasi dapat beradaptasi terhadap lingkungan perairan sekitarnya. Coral reef ecosystems are one of the main ecosystems in coastal and marine areas which have a very large role, especially in supporting the fisheries and tourism sectors. The coastal waters of Harlen Kampung Tablasupa have a good coral reef ecosystem and have the potential to be utilized for improving people's welfare. Ironically, several locations have been damaged by fishing using blast fishing and tuba roots poison. Therefore, rehabilitation efforts that have been damaged are needed, one of which is coral transplantation. Coral transplantation is a technology to multiply colonies by utilizing the asexual reproduction of corals by fragmentation of a coral colony. Transplantation aims to accelerate the regeneration of corals that have been damaged. The method used is the Spider Method. This activity was carried out by the Center for the Study of Marine and Fisheries Resources, University of Cenderawasih, involving several partners with funding support from PT PLN (Persero) Unit Induk Wilayah Papua and Papua Barat through the PLN Care Program. The results showed that the Spider method was very successful with a 92% survival rate. The survival rate is thought to be due to the selection of the right location and the ability of the transplanted species to adapt to the surrounding aquatic environment.
