Abstract

This study aims to determine the catch and development of CPUE from catches landed at the Kema Dua Fish Landing Base. The method used in this study is the Descriptive Method. The data collected is in the form of primary data by observation and interviews and secondary data in the form of catches and fishing efforts from 2017-2021. The data obtained will be analyzed using graphs and CPUE calculations to determine the development between production (catch) and capture effort (effort). Based on the results of the research carried out, it can be concluded that the bottom fishing catch landed at the Kema Dua Fish Landing Base consists of 9 types of demersal fish, namely Saramia fish (Etelis Carbunculus) 526,990 kg (25.5%), Lolosi (Caesio cuning) 459,855 kg (22.2%), Tola (Pristipomoides filamentosus) 404,490 kg (19.5%), Tariasan (Aphareus rutilans) 323,910 kg (15.6%), and Kurisi (Nemipterus sp) 213,675 kg (10.3%), Rahiang (Etelis coruscans) 53,300 kg (2.6 %), Kuwe (Carangoides coeruleopinnatus) 42,285 kg (2.0 %), Snapper (Lutjanus sp) 27,100 kg (1.3 %), Grouper (Epinephelus sp) 18,390 kg (1.0 %). The development of the Catch value per Unit Effort (CPUE) for 5 years (2017-2021) based on the catch landed at PPI Kema Dua fluctuates every year. The highest CPUE value occurred in 2021 at 3,452 kg/trip and the lowest CPUE value occurred in 2019 at 2,670 kg/trip.

Abstract

ABSTRACT The focus of this research is the Main Dimension Characteristics of Purse Seine Vessels based at the Tumumpa Coastal Fishing Port in Manado City, which includes the ratios or comparisons of the vessel's main sizes (LOA/BOA, LOA/D, and BOA/D), the relationships between the main sizes of the vessel (LOA vs BOA, LOA vs D, and BOA vs D), and the relationship of the main size of the vessel (LOA) with the carrying capacity (GT) and engine power (HP).The data analysis method was carried out using descriptive analysis through cross-tabulation and data presentation in the form of a curve of the relationship between the main ship sizes, the relationship between the main ship sizes, and the relationship between the main size of the ship's length (LOA) with load capacity (GT) and propulsion engine power (HP). Data analysis used the 'Curve Expert' application with a mathematical model: (1) the relationship between the main ship sizes using linear regression analysis Y=a+bx, and (2) the relationship between LOA with load capacity (GT) and propulsion engine power using non-linear regression analysis. The results of this study indicate that the comparison of the main dimensions of purse seine vessels in PPP Belang still has vessels that do not comply with the standard values proposed by Fyson (1985). There is a positive relationship between the main dimensions of the vessel (LOA/BOA, LOA/D, BOA/D) and between the main dimensions of the vessel (LOA) with load capacity (GT) and engine power (HP).

Abstract

This research aims to determine the effect of redesigning the hull of a small purse seine ship on its motion resistance. The research was carried out using a small purse seine ship prototype in Manado by changing the length-breath-depth ratio based on the main dimensions of the ship, resulting in three new hull designs coded K-0 (prototype), K-1, K-2, and K- 3. Maxsurf modeler and Maxsurf resistance were used to run a simulation set of three loading conditions (light, half, full) and speed (low, medium, high). The research results show that changes in ship hull design affect the resistance and thrust of the ship. There is a difference in resistance between the ship with the redesigned hull and the prototype, where the smallest difference is shown by K-3. In addition to changes in hull design, changes in ship loading conditions, Froude number, and ship speed lead to increases in ship resistance and thrust. Based on the average allowance (sea margin or service margin) in shipping lanes, the need for propulsion power and the number of propulsion power vessels K-0 (prototype) and K-3 are still better than K-1 and K-2. Keywords: purse-seiner, resistance, speed, propulsion

Abstract

The Java Sea plays a strategic role in supporting maritime transportation and trade in Indonesia, particularly as a key connector between Java Island and surrounding regions. However, the high intensity of maritime activity in this area is accompanied by a significant risk of maritime accidents, often triggered by high waves and extreme weather conditions. This study aims to analyze the characteristics of high wave events in the Java Sea to support maritime safety and disaster risk mitigation, in accordance with the SOLAS (Safety of Life at Sea) international standards. The analysis utilizes numerical wave model data from Wavewatch III and wind speed data from the Semarang Maritime Meteorological Station for the period of 2004–2023. The results reveal a bimodal annual pattern, with two peaks and two troughs in both wave height and wind speed cycles. Monthly occurrences of high wave events are most frequent in January and August. Annual trend analysis shows an increase of 1–2 events per year for waves with heights of 1.25–1.5 meters, and 1–3 events per year for waves of 1.5–2.5 meters. Meanwhile, waves exceeding 2.5 meters exhibit either a constant trend or statistically insignificant changes. These findings are expected to contribute to the development of early warning systems and policy frameworks aimed at enhancing maritime safety in the Java Sea region. Keywords: Java sea, high wave, wind speed, numerical model, SOLAS ABSTRAK Laut Jawa memiliki peran strategis dalam mendukung pelayaran dan perdagangan laut di Indonesia, khususnya sebagai penghubung utama Pulau Jawa dengan wilayah sekitarnya. Namun, tingginya intensitas aktivitas maritim di kawasan ini juga disertai dengan tingginya risiko kecelakaan laut, yang salah satunya dipicu oleh kondisi gelombang tinggi dan cuaca ekstrem. Penelitian ini bertujuan untuk menganalisis karakteristik kejadian gelombang tinggi di Laut Jawa sebagai upaya mendukung keselamatan pelayaran dan mitigasi bencana maritim, sejalan dengan standar internasional SOLAS (Safety Of Life At Sea). Analisis dilakukan menggunakan data model numerik Wavewatch III serta data kecepatan angin dari Stasiun Meteorologi Maritim Semarang selama periode 2004–2023. Hasil menunjukkan adanya pola dua puncak maksimum dan dua minimum dalam siklus tahunan tinggi gelombang dan kecepatan angin. Kejadian gelombang tinggi bulanan tertinggi terjadi pada Januari dan Agustus. Tren tahunan memperlihatkan peningkatan kejadian gelombang dengan ketinggian 1,25–1,5 m sebanyak 1–2 kejadian per tahun, serta gelombang 1,5–2,5 m sebanyak 1–3 kejadian per tahun. Sementara itu, gelombang lebih dari 2,5 m menunjukkan tren yang cenderung konstan atau tidak signifikan secara statistik. Temuan ini diharapkan dapat menjadi dasar dalam pengembangan sistem peringatan dini serta kebijakan keselamatan pelayaran di wilayah Laut Jawa. Kata kunci: laut Jawa, gelombang tinggi, kecepatan angin, model numerik, SOLAS

Abstract

Hull line determines the ship motions in adapting to the ocean conditions, and therefore, ships require a flexibly appropriate hull line to have a highly safe sailing trip.   This study aims to determine influence of small purse-seiner hull line redesign on the ship's motion, namely rolling, heaving, and pitching which can be observed as a Response Amplitude Operator (RAO) due to the sea conditions. The hull lines were redesigned by manipulating the ship's breadth (B) and depth (D) based on the Manado prototype, resulting in three new hull forms (ships B, C, D) and one prototype control (ship A). Data input and simulation used the Maxsurf Modeler Advanced and Maxsurf Motions Advanced applications to analyze motion responses at different wave angles (head sea 180°, bow quartering sea 135°, and beam sea 90°) under average load and service speed conditions. The findings demonstrated that each ship had a unique RAO for heave, roll, and pitch motion. In heave and pitch motion, ship D had a best RAO, but in roll motion, ship C had the best RAO. The rolling and pitching motions of all ships have met the minimum standard of the general operability limiting criteria for ships at all conditions, while the rolling motion at the wave coming of 90° was met at the slight and moderate conditions. Keywords:       Heaving motion, North Sulawesi-Indonesia, pitching motion, rolling motion, ship motion
