Abstract

Understanding the vulnerability of livelihoods is very important in identifying and developing alternative livelihoods for communities to achieve their welfare. Alternative livelihoods are intended so that people do not depend their livelihoods entirely on the use of natural resources. Thus, the exploitation pressure on natural resources, especially the coast and the sea can be minimized. The purpose of this study is to analyze the level of livelihood vulnerability of the people in Depapre Bay using the Livelihood Vulnerability Matrix method. The results of the analysis showed that the level of vulnerability of people's livelihoods is in the vulnerable category (2.44), where the variable value is still low in terms of disaster disruption, social networks, savings, means of production, production costs, and fulfillment of basic needs.Keywords: Vulnerability; Livelihood; Coastal Community; Exploitation Pressure; Natural Resources; Teluk Depapre; Papua

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

This study aims to determine the diversity, distribution, and ecological index of coral fish from the Pomacentridae family in the coral reef ecosystem of Jayapura City. Reef fish observations were carried out in April 2020 at seven study sites. The fish observation was carried out at a depth of 3 to 5 m using the Underwater Visual Census method. Ecological indices were determined using PAST software (PAleontological Statistics) version 4.01, while the similarity index between study sites was determined using PRIMER 7 software. The results showed that the number of coral fish species of Pomacentridae family was 35 species with a total of 346 individual fish. The species distribution was very diverse and no fish species were found at all study sites. The diversity index ranges from 0.572 to 2.215 (low to moderate category), the evenness index ranges from 0.431 to 0.886 (medium to high category), and the dominance index ranges from 0.145 to 0.616 (low to moderate category). The diversity index at Base-G, Pulau Kayupulo, and Lampu Merah sites shows the fish community is classified as medium diversity with high evenness. There are similarities between study sites, where the species N. filamentosus contributed to the formation of group A (Base-G and Argapura 1 sites), while P. moluccensis, C. margaritifer, and P. taeniometopon species contributed to the formation of group B (Argapura 2, Pulau Kosong 1, Pulau Kosong 2, Pulau Kayupulo, and Lampu Merah sites).Keywords: Coral reef; Reef fish; Ecological index; Community structure; Similarity index

Abstract

Sedimentation can be one of the factors that limit coral life because it can cover coral polyps, in high numbers it can even cause coral death. The purpose of this study was to determine the rate of sedimentation in the coral reef ecosystem and to determine the condition of coral reef cover in the waters of Kampung Yakore. This research was carried out from January to May 2021. The method used in this study was to collect sediment in a sediment trap for 14 days and the LIT (Line Intercept Transect) method to observe the condition of live coral cover. Data were collected at 3 stations at a depth of 3 m and 5 m. The results showed that the sedimentation rate in the waters of Kampung Yakore was moderate to very heavy where the highest sedimentation rate was at station 3 with a depth of 5 m. The sedimentation rate ranged from 30.28 – 67.74 mg/cm²/day at a depth of 3 m. Meanwhile, at a depth of 5 m, the sedimentation rate ranged from 68.30 – 133.21 mg/cm²/day. This shows that the sedimentation rate in the waters of Kampung Yakore is at a very heavy impact level. It is suspected that the high sedimentation rate is caused by the time when data collection is carried out during the rainy season so that the river discharge is getting bigger and carrying sediment to the sea. The percentage of live coral cover in the waters of Kampung Yakore was classified as "moderate" to "good" with percentages ranging from 39.28% - 71.76% at a depth of 3 m and ranging from 30.7% - 56.12% at a depth of 5 m. The highest percentage of the cover was at station 2 with a depth of 3 m, which was 71.76%.Key Words: Sedimentation Rate; Coral Reef Ecosystem; Coral Cover; Yakore VIllage

Abstract

Kearifan lokal merupakan pengetahuan yang mengandung nilai-nilai luhur dan dipedomani, diterapkan dan ditaati oleh masyarakat secara turun-temurun dan telah terbukti berhasil dalam pengelolaan sumber daya pesisir dan laut, sehingga masih sangat relevan digali dan diadopsi dalam sistem pengelolaan modern yang seringkali tidak dapat menjawab tujuan dari pengelolaan tersebut. Tujuan penelitian ini adalah untuk menggali sistem kearifan lokal di Kampung Muris Besar, guna mendukung pengelolaan sumber daya pesisir dan laut berkelanjutan sebagai model pengelolaan. Penelitian ini menggunakan tiga metode pendekatan, yakni studi literatur, survei, dan wawancara mendalam. Berdasarkan hasil penelitian, didapatkan bahwa sistem kearifan lokal Dabom memiliki nilai-nilai yang sangat tinggi terkait dengan pengelolaan sumber daya pesisir dan laut, yang masih dipegang teguh oleh masyarakat Kampung Muris Besar. Oleh karena itu, praktik Dabom tidak hanya menjadi model pengelolaan di kampung Muris guna mempertahankan sumber daya pesisir dan laut yang ada, tetapi juga telah menjaga eksistensi masyarakat Kampung Muris Besar sebagai Masyarakat Adat dalam mengelola sendiri sumber daya yang dimilikinya.Local wisdom is knowledge that contains noble values and is guided, applied and adhered to by the community from generation to generation and has been proven to be successful in managing coastal and marine resources so that it is still very relevant to be explored and adopted in modern management systems. The purpose of this study is to explore the local wisdom system in Muris Besar Village in order to support sustainable coastal and marine resource management as a management model. This research uses three approach methods, namely literature study, survey, and in-depth interviews. Results indicated that the Dabom local wisdom system had very high values related to the management of coastal and marine resources which the people of Muris Besar Village still adhere to. Therefore, the practice of Dabom has not only become a management model in Kampung Muris Besar to maintain existing coastal and marine resources, but has also maintained the existence of the people of Kampung Muris Besar as Indigenous Peoples in managing their own resources.

Abstract

Teluk Depapre  telah ditetapkan sebagai kawasan strategis nasional penunjang pembangunan di Provinsi Papua dan juga akan diusulkan sebagai pencadangan kawasan konservasi perairan dipastikan telah memberikan dampak terhadap masyarakat khususnya masyarakat lokal di sekitar kawasan. Tujuan dari penelitian ini, yakni mengidentifikasi, menentukan dan merumuskan strategi pengembangan mata pencaharian alternatif. Penelitian ini menggunakan empat pendekatan yaitu: studi kepustakaan, observasi dan survei serta Participatory Rural Appraisal (PRA). Metode analisis data yang digunakan adalah analisis deskriptif, Coastal Livelihood System analysis,  analisis Rating Scale dan analisis kelayakan usaha. Berdasaran analisis rating scale, didapatkan sebanyak tiga mata pencaharian alternatif yang teridentifikasi yang sangat potensial dikembangkan, yakni usaha pembuatan ikan asap, penyewaan pondok wisata dan penangkapan ikan dengan bantuan rumpon. Kemudian hasil analisis kelayakan secara finansial dari didapatkan rasio pendapatan terhadap total biaya (BCR) dari ketiga jenis mata pencaharian alternatif tersebut, maka rasio pendapatan tertinggi yakni usaha pembuatan ikan asap (3,70), kemudian usaha penyewaan pondok wisata (2.64), dan penangkapan ikan dengan bantuan rumpon (1,62). Berdasarkan efisiensi penggunaan investasi (ROI), maka usaha ikan asap lebih efisien yakni (90%), usaha penyewaan pondok wisata (85%), dan penangkapan ikan dengan bantuan rumpon (58%). Berdasarkan Payback Period (PP), yakni berdasarkan tingkat pengembalian investasi yang lebih cepat dalam satu tahun yakni tercepat usaha ikan asap (0.04), usaha penyewaan pondok wisata (2.17), dan usaha penangkapan ikan dengan bantuan rumpon (2,32). Mengingat kendala-kendala yang ada dalam pengembangan usaha mata pencaharian tersebut khususnya, ketersediaan bahan baku, modal, dan minat serta penguasaan teknologi yang masih rendah maka perlu strategi pelatihan dan pendampingan oleh stakeholder yang terkait.

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.
