Abstract

Bigeye tuna (Thunnus obesus) and Yellowfin tuna (Thunnus albacares) are a marine commodity that has high nutritional content and economic value in the market. However, based on data from Palabuhanratu Archipelago Fishing Port, there has been a high decrease in the catch of Bigeye tuna and Yellowfin tuna since 2016 although slightly increased in the following year, so it is necessary to analyze the size trends of them as a target fish of many fishermen at the port. The purpose of this study is to determine the size trend of Bigeye and Yellowfin tuna for the next few years and to determine the steps to maintain their sustainability. The method used in this research is a case study and analyzed using regression analysis. The results showed that the size trend of Bigeye tuna and Yellowfin tuna catch until 2022 will tend to decline. This indicates the occurrence of overfishing so that it does not provide opportunities for fish to grow and develop. Therefore, catch control efforts are needed to maintain the sustainability of fish stocks.

Abstract

The increasing number of tourist visits and activities of coastal communities affects the distribution of marine waste on the Pangandaran coast, resulting in waste generation that pollutes the coastal environment. This is due to a lack of awareness in disposing of waste in its proper place, a lack of cleaning facilities and a waste transport fleet by the Pangandaran district government. The aim of this research is to provide an evaluation regarding the distribution of marine waste and its management on Pantai Timur, Pantai Barat and Pantai Madasari. Using Survey Method and Driving Force-Pressure-State-Impact-Response data analysis. The research location was carried out in three locations, namely on the Pantai Timur, Pantai Barat and Pantai Madasari. The results of this research are that the distribution of marine debris on Pantai Timur, Pantai Barat and Pantai Madasari is categorized as moderate. This causes pressure on coastal areas where there is waste generation at several research stations. The most common type of waste is plastic waste with a percentage of 45-54% on Pantai Timur, 36-55% on Pantai Barat and 43-51% on Pantai Madasari. The type of waste that is least found is rubber with a percentage of 2-3%. The actions taken by Pangandaran Village and the Pangandaran Regency Environment and Hygiene Service (DLHK) are waste management using a collect-transport-dispose system, community service to clean the beach with the community on Fridays, and the availability of several rubbish bins at every distance of 10 meters. Waste management on Pantai Madasari is managed by the village government, where this authority is handed over to Village-Owned Enterprises using a collect-transport-dispose system and burned directly at the temporary disposal site (TPS).Keywords: Coastal; DPSIR; plastic; pollution; waste distribution

Abstract

Comparison between the usages of fisheries resources and the allowable catch in Indonesia is in the fully exploited category, which means that fishing efforts are maintained with close monitoring. This study aims to analyze whether fisheries management practices, especially in Palabuhanratu Nusantara Fishing Port, have been managed sustainably or not based on indicators in the Ecosystem Approach to Fisheries Management (EAFM), and identify strategies for developing and strengthening fisheries management in the area according to the results of the EAFM evaluation. The method used is a survey method using composite analysis and flag modeling visualization techniques. This method will assess the EAFM indicator as a multi-criteria system that ends in a composite index in the form of a score of values related to the level of achievement or sustainability of fisheries management by EAFM principles. The results show that the mean composite value for all EAFM domains is 66.72 with a good category. Then the strategies for developing and strengthening the sustainability of fisheries management at Palabuhanratu Nusantara Fishing Port are through increasing the status of the port to become an Ocean Fishery Port, increasing the added value of the economy of fishery products, strengthening the regulations with fair law enforcement, optimizing the usage of technology in fisheries management, and strengthening the system fishery business capital. It is hoped that similar research can be carried out at least at the coastal fishing port to ocean fishing port, as one of the bases for determining the sustainability of fisheries management at a wider level.

Abstract

Bojong Salawe is a coastal area with unique characteristics due to a confluence of three rivers that flow through Cijulang, Cijalu, Cialit and into the Indian Ocean. With complex oceanographic conditions, the sediment transport patterns at Bojong Salawe needs to be contemplated, especially the coastal’s utilization which is quite productive. This study aims to determine the sediment types, the sediment transport patterns and the effect of sediment transport on abrasion or accretion which are supported by hydrodynamic parameters modelling such as wind, currents and tides in the west and east monsoons using hydrodynamic modules and sediment transport in MIKE 21. The results showed that the sediments in this study is 80% sandy silt and 20% sand. The sediment transport pattern models in both the west and east monsoons tend to be influenced by tidal currents, sediment types and the season itself. West monsoon has a higher sediment concentration which ranges from 0 to 8.4 kg/m3 compared to the East Monsoon with a range of 0-4 kg/m3. The effect of sediment transport on the average bed level was 0.71861 m in the west monsoon and 0.37586 m in the east monsoon whereas in the estuary (research station), the average change in West Monsoon is 0.00861 m (ST 1) and 0.07107 m (ST 2) and in the East Monsoon, it is 0.01003 m (ST 1) and 0.01147 m (ST 2). This bed level change tends to increase, indicating that the Bojong Salawe coast has experienced sedimentation (accretion).

Abstract

Coastal areas have an important role and have high natural resources that can be utilized for human life. Over time, the increase in population is directly proportional to the activities and utilization of coastal areas, which puts great pressure on coastal areas. One of the pressures that occur in coastal areas is heavy pollution. This research aims to see the distribution of heavy metals especially Cd, Cu and Pb in the coastal areas of Jakarta Bay and Semarang Bay and to see the differences in heavy metal content from the two gulfs. The data used in this study is secondary data, which consists of data on heavy metals, current velocity, pH and water temperature. The period of data used in this research are from 2016 to 2019, The method used in this study is the GIS method with descriptive analysis. The comparison of concentrations from two bays shows a higher mean of concentration value of heavy metals cadmium (Cd) in Semarang Bay (2016, 2017, 2019) and heavy metals of copper (Cu) in Jakarta Bay (2016 and 2018). Meanwhile, the concentration value of heavy metal lead (Pb) was higher in Jakarta Bay (2016, 2017, 2018), yet in 2019, the two locations have the same concentration value of heavy metal lead (Pb).Keywords:Coastal areaDistributionHeavy metalsJakarta BaySemarang Bay

Abstract

Pemenuhan kebutuhan gizi pada remaja erat kaitannya dengan konsumsi protein hewani, salah satunya adalah konsumsi ikan. Pola konsumsi remaja yang beragam membuat asupan pemenuhan gizi yang tidak maksimal. DKI Jakarta merupakan provinsi padat penduduk yang memiliki potensi sumberdaya perikanan yang besar. Sebagai wilayah pesisir, Kepulauan Seribu dan Teluk Jakarta menjadi wilayah potensi perikanan DKI Jakarta. Namun, tingkat produksi perikanan yang tinggi tidak menjamin masyarakatnya juga memiliki tingkat konsumsi ikan yang tinggi. Sehubung dengan itu, data informasi mengenai tingkat konsumsi ikan di satu wilayah sangat diperlukan. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berpengaruh dengan tingkat konsumsi ikan pada remaja. Metode analisis yang digunakan adalah analisis regresi linear berganda dan analisis deskriptif menggunakan program SPSS (Social Package of Statistics Software). Data yang didapatkan bersumber dari data primer dengan penyebaran kuisioner melalui Google Formulir yang disebar melalui media sosial. Teknik pengambilan sampel yang digunakan pada penelitian ini adalah cluster random sampling. Responden berjumlah 360 responden yang masing-masing terbagi menjadi 60 responden di 5 kotamadya dan 1 kabupaten. Keempat faktor yaitu kebiasaan makan di masa kanak-kanak, pengetahuan gizi, pendapatan orang tua, dan preferensi konsumen berpengaruh nyata terhadap tingkat konsumsi ikan pada remaja di DKI Jakarta.
