Abstract

ABSTRACT Karimunjawa National Park is one of the national parks that have the objective to maintain fish populations in the Java Sea, where one of them is grouper. Grouper is one of the target fish in the national park. The objective of this study is to assess the conditions and dynamics of the grouper fishery in Karimunjawa National Park. Fish landing surveys were conducted to collect the data. Fishing gear types, grouper species, and weight of each species were collected. Calculation of Catch per Unit Effort (CPUE) per month and two-way ANOVA statistical tests were used for data analysis. Results of this study indicated that catches of grouper using speargun was significantly higher than the catch using handline. There was a seasonal cycle of the grouper catch, where the value of the highest CPUE occurred in transitional season between the west and east monsoon season, from March to May. Key words: CPUE, grouper fishery, Karimunjawa National Park ------- ABSTRAK Taman Nasional Karimunjawa merupakan salah satu taman nasional yang salah satu tujuannya untuk mempertahankan populasi ikan di Laut Jawa, dimana salah satunya adalah perikanan kerapu. Ikan kerapu merupakan salah satu target penangkapan di perairan Taman Nasional Karimunjawa. Tujuan penelitian ini adalah mengetahui kondisi dan dinamika perikanan kerapu di Taman Nasional Karimunjawa. Survei pendaratan ikan dilakukan untuk pengumpulan data. Data yang dikumpulkan dalam penelitian ini adalah alat tangkap yang digunakan untuk menangkap ikan kerapu, jenis hasil tangkapan, dan berat masing-masing jenis hasil tangkapan setiap trip. Perhitungan nilai Catch per Unit Effort (CPUE) setiap bulan dan uji statistik two ways ANOVA digunakan untuk analisis data. Hasil penelitian ini menunjukkan bahwa hasil tangkapan ikan kerapu dengan menggunakan speargun lebih tinggi dan berbeda nyata secara statistik dibandingkan hasil tangkapan dengan menggunakan pancing. Terdapat siklus musiman hasil tangkapan, dimana nilai CPUE tertinggi terjadi pada musim peralihan antara musim barat dan musim timur yakni dari bulan Maret hingga Mei. Kata kunci: CPUE, perikanan kerapu, Taman Nasional Karimunjawa

Abstract

The increase of exhaust emissions from longline vessels has long-term impacts. Accordingly, management measures are necessary, and therefore, information about the current status of exhaust emissions from longline vessels is required. This research was intended to estimate exhaust emissions of longline vessels based on fuel consumption. The result was presented in Fuel Use Intensity (FUI) per fish production calculated in kg and 1,000 Rupiah income. This research was conducted at Nizam Zachman Oceanic Fishing Port, focusing on longline vessels between 51-100 GT. The result shows that the average fuel consumption is 179 tons per vessel, contributing 1.328 kg of CO, 1.964 kg of NOx, 3.393 kg of SOx, and 54 kg of PM. Furthermore, inaccuracy issues found in statistical reports caused FUI of longline vessels to be remarkably higher than the world FUI for a similar group. This research concludes that the operation of longline vessels was fuel inefficient.
