Abstract

The implementation of the ship maintenance management system on Rear Admiral Jhon Lie's training ship did not run optimally, which impacted the less-than-optimal condition of various training ship equipment because the crew did not carry out the ship maintenance system according to the procedure, resulting in the incident that the ship's anchor winch operation did not function optimally when the ship was anchored in Belang Port, Southeast Minahasa. This study aims to identify and analyze the positive and significant effect of the planned maintenance system on shipping safety. The primary data collection methods used in this study were questionnaires and interviews. In this study, data processing and presentation were in the form of diagrams and path analysis with structural equation modeling (SEM-PLS) using SmartPLS. From the results of the data analysis, the R-square value of shipping safety (Y) is 0.307, which means that the planned maintenance system (X1) and ship maintenance (X2) can affect shipping safety (Y) by 30.7%. Ship maintenance (X2) has a significant effect on sailing safety (Y), with P-values = 0.033 0.05 (hypothesis accepted). The planned maintenance system (X1) has a significant effect on sailing safety (Y), with a P-value of 0.037 0.05 (hypothesis accepted). As a result of the analysis, it was found that the planned maintenance system has a significant effect on shipping safety.

Abstract

Global weather phenomena cannot be separated from the interaction between the ocean and the atmosphere. El Nino and La Nina are phenomena that were related to the interaction of the sea and the atmosphere which affects many aspects, including the fertility of waters. Indicators of the fertility of water could be determined from the distribution of sea surface temperature and chlorophyll-a concentration. This study aims to analyze variations in the distribution of sea surface temperature and chlorophyll-a in the Maluku Sea when the El Nino and La Nina phenomena are activated. The results showed that when the El Nino phenomenon was activated, there was a decrease in sea surface temperature and an increase in the concentration of chlorophyll-a from normal conditions. Besides, when the La Nina phenomenon was activated, there was an increase in sea surface temperature and a decrease in the concentration of chlorophyll-a from normal conditions. Spatial interpretation when El Nino and La Nina are activated showed low values with a distribution indicating the mixed proceed for the sea surface temperature parameter and showed higher values with an even distribution for the chlorophyll-a parameter. Keywords: Sea Surface Temperature, Chlorophyll-a, El Nino, La Nina. Abstrak Fenomena cuaca secara global tidak bisa lepas kaitannya dengan interaksi antara laut dan atmosfer. El Nino dan La Nina merupakan salah satu fenomena yang berkaitan dengan interaksi laut dan atmosfer yang berpengaruh terhadap banyak aspek termasuk kesuburan suatu perairan. Indikator kesuburan suatu perairan dapat ditentukan dari distribusi suhu permukaan laut dan konsentrasi klorofil-a. Penelitian ini bertujuan untuk menganalisa variasi distribusi suhu permukaan laut dan klorofil-a di perairan Laut Maluku saat fenomena El Nino dan La Nina aktif. Hasil penelitian menunjukkan bahwa saat fenomena El Nino aktif terjadi penurunan suhu permukaan laut dan peningkatan konsentrasi klorofil-a dari kondisi normal. Sebaliknya saat fenomena La Nina aktif terjadi peningkatan suhu permukaan laut dan penurunan konsentrasi klorofil-a dari kondisi normal. Interpretasi spasial saat El Nino dan La Nina aktif menunjukkan nilai yang rendah dengan sebaran yang menunjukkan proses mixing untuk parameter suhu permukaan laut, dan menunjukkan nilai yang lebih tinggi dengan sebaran merata untuk parameter klorofil-a. Kata kunci: Suhu Permukaan Laut, Klorofil-a, El Nino, La Nina.

Abstract

Sulawesi waters are directly affected by the dynamics that occur in the Pacific Ocean. The ENSO phenomenon that occurs in the Pacific Ocean can also be felt in the waters of the Sulawesi Sea. The dynamics of oceanographic parameters can cause climate change. The extreme impact of climate change is mainly the occurrence of rising temperatures and seasonal shifts. The purpose of this study is to analyze the variability of spatial and temporal anomalous distribution of sea surface temperature and chlorophyll-a. This study used monthly AQUA Modis image data, conducted by analyzing the spatial and temporal distribution of sea surface temperatures during the two decades of the period 2003 - 2022. This analysis is based on abnormal values obtained from subtracting parameter values from historical values (the average value of all data). The results of spatial variability analysis of sea surface temperature and chlorophyll –show anomalous variations occur in the western and transitional season periods I, while in the eastern season and transition II positive anomalous values dominate the eastern waters negative anomalies dominate the western waters opposite to chlorophyll – a. This study showed that there was an increase in sea surface temperature slope by 0.000840C / year while in chlorophyll - a there was a decrease in slope by 0.00072mg / m3 / year.

Abstract

An optimization study of the KLT eluent composition was carried out on the ethanolic extracts of 3 ascidian samples (Ascd-2, Ascd-3, Ascd-4) and 2 sponge samples (Spons-2 and Spons-3). The Ascidia and Sponge marine invertebrate samples were collected from Malalayang, Manado City's coastal waters, and were not identified. This research is a preliminary test to determine the best eluent composition to separate the compounds in the ascidian and sponge sample extracts. Extracted samples with ethanol solvent using the maceration method for 3 x 24 hours at room temperature followed by evaporation at 400C to obtain a thick ethanol extract. The composition of the eluent used is as follows: Hexane: Ethyl Acetate = 3: 7, Hexane: Ethyl Acetate = 2: 3, Hexane: Ethyl Acetate = 1: 9, Methanol: Ethyl Acetate = 1:1, and 100% Methanol. KLT analysis of the extracts from the ascidia and sponge samples showed that most of the variations in eluent composition used could not separate the compound components in the extracts, except the 100% methanol composition which could separate the compounds in the spongs 3 samples.

Abstract

Indonesia is a tropical country with high marine biodiversity, including sea cucumber. The high demand for sea cucumber has led fishermen to catch sea cucumber regardless of the type or size suitable for harvesting. The lack of cultivation and regulations governing the protection of sea cucumbers has caused some species to be endangered. Sea cucumber species with high selling prices are increasingly difficult to find in West Likupang District. This study aims to identify strategies for managing sea cucumber fisheries sustainably and provide policy recommendations for their sustainable management in West Likupang District. This study used a survey method and then analyzed it with a SWOT analysis (strengths, weaknesses, opportunities, threats). The SWOT analysis reveals several strategies for achieving sustainable sea cucumber fisheries: legislation, conservation efforts, aquaculture development, regulated fishing, proper post-harvest handling, and educating fishermen on regulations. Keywords: Management, regulation, conservation, sea cucumber, SWOT Abstrak Indonesia merupakan negara tropis yang mempunyai keanekaragaman hayati laut yang tinggi, salah satunya ialah sumber daya trepang (Holothuridea). Permintaan pasar yang tinggi terhadap trepang, menyebabkan nelayan menangkap trepang tanpa mengindahkan jenis dan ukuran yang layak panen. Belum adanya budi daya dan regulasi yang mengatur perlindungan terhadap trepang menyebabkan beberapa spesies sudah terancam punah. Spesies trepang dengan harga jual yang tinggi makin sulit ditemukan terutama di Kecamatan Likupang Barat. Penelitian ini bertujuan untuk menentukan strategi pengelolaan sumber daya perikanan trepang, untuk mencapai perikanan trepang yang berkelanjutan, dan membuat rujukan atau rekomendasi kebijakan untuk pengelolaan sumber daya perikanan trepang (Holothuroidea) yang berkelanjutan secara umum Di Provinsi Sulawesi Utara, khususnya di Likupang Kabupaten Minahasa Utara. Penelitian ini menggunakan metode survei kemudian dianalisis dengan analisis SWOT (kekuatan, kelemahan, peluang, dan ancaman). Berdasarkan hasil analisis, terdapat beberapa strategi yang dapat dikembangkan untuk mencapai perikanan trepang yang berkelanjutan, yakni: regulasi berupa peraturan perundangan, upaya konservasi, pengembangan usaha budidaya, penangkapan yang terukur, penanganan pasca panen/penangkapan dari alam, dan sosialisasi kepada nelayan terkait peraturan Kata kunci: Pengelolaan, regulasi, konservasi, trepang, SWOT
