Abstract

AHTS vessels are tasked with performing heavy-duty operations such as towing and deploying anchors, which are critical steps in the installation and relocation of platforms at designated locations. The Dynamic Positioning System (DPS) consists of several separate modules, each performing its specific function, and collectively counteracting environmental disturbances such as wind, currents, and waves. The operation of the dynamic positioning system is carried out by the captain, assisted by ship officers who hold DPO certification. As the DP system operator, the DPO is responsible for monitoring, evaluating, and controlling the performance of the DP system to ensure the vessel remains stable and in the correct position during operations in waters with adverse weather conditions. This study was conducted to investigate Dynamic Positioning (DP) on the AHTS vessel OPS AORA, which was operating suboptimally. The adverse weather conditions caused the vessel to lose its position. This incident disrupted the vessel's operations during DP operations at the Borr Thor offshore rig in the Bukit Tua Field of Petronas. The study was conducted using a qualitative case study approach. The impact of adverse weather conditions on the Dynamic Positioning (DP) system in the context of offshore AHTS vessel operations was explored through interviews with experienced masters and officers. The research findings revealed that sensor and navigation malfunctions, reduced thruster efficiency, and decreased vessel stability caused the DP system to lose accuracy, potentially leading to position failure and increased accident risks. The implementation of technical and procedural mitigation strategies, such as sensor redundancy, real-time monitoring of sea conditions, and enhancing operator competence, can effectively control the negative impacts of adverse weather conditions.

Abstract

Potensiometer dapat digunakan sebagai sensor untuk mengukur derajat putaran kemudi dengan membaca nilai resistansinya untuk diubah ke dalam nilai digital manggunakan analog to digital coverter yang terdapat di arduino. ADC atau disebut juga dengan Analog to Digital Converter merupakan fitur yang di miliki oleh arduino sebagai mikrokontroler guna membaca sinyal analog kemudian di konversikan menjadi sinyal digital (Elgamar, 2018). Kemudi kapal harus memenuhi persyaratan-persyaratan yang diharuskan untuk kepentingan dan keselamatan serta sesuai yang diisyaratkan dalam SOLAS 74 aturan 29 Bab II mengenai perangkat kemudi. Perangkat kemudi utama pada saat kapal melaju dengan kecepatan ekonomis maksimum, harus dapat disimpangkan sebesar 35º ke kiri/ ke kanan dalam waktu 28 detik, dari posisi port 35 derajat ke starboard 35 derajat atau sebaliknya, saat putaran mesin maksimum dan beban maksimum dalam jangka waktu maksimum 28 detik (Yusim, 2021). Hasil pembacaan potensiometer yang sudah dikonversi menjadi digital dikirimkan ke komputer melalui komunikasi serial USB dengan software yang digunakan visual basic. File visual basic dalam komputer ini berbentuk file berextensi .exe yang sifatnya executable atau dengan kata lain dapat langsung digunakan. Potensiometer yang digunakan adalah potensio dengan resistansi 100 k ohm dan tegangan referensi 5 volt dicatu dari tegangan USB komputer, hasilnya dikonversi ke digital digunakan untuk menentukan berapa derajat kemudi kapal akan berbelok ke kanan (starboard side) atau ke kiri (port side).

Abstract

Minyak berat sejenis Heavy Fuel Oil (HFO) memiliki karakteristik berwarna hitam, mengandung partikel padat dan residu, pada suhu rendah sangat kental seperti bitumen. Nilai density HFO berkisar antara 0.92-0.99 kg/L dengan kekentalan yang ada dipasaran 180 dan 380 Cst. Perbedaan tempat bunker seringkali berakibat pada perbedaan technical data bahan bakar yang disuplai ke kapal. Efek yang sering terjadi dari perubahan nilai density adalah terganggunya proses treatment pada purifier. Penurunan efisiensi pengisian HFO service tank karena overflow pada purifier merupakan masalah utama yang sering timbul karena nilai density. Berdasarkan fenomena yang terjadi pada proses purifikasi Heavy fuel Oil pasca bunker maka perlu dilakukan studi dalam menentukan gravity disc pada FO purifier. Studi dilakukan dengan tujuan untuk memberikan solusi kepada engineer yang bertugas di kapal-kapal niaga apabila terjadi masalah serupa. Penelitian dilakukan menggunakaan metode studi kasus terhadap permasalahan riil yang terjadi di atas kapal. Asumsi yang digunakan dalam memecahkan persoalan dengan membatasi tangki tempat proses pencampuran di settling tank. Bahan bakar HFO tersisa dalam storage tank adalah 0%, sedangkan bahan bakar tersisa di settling tank 4 KL dengan specific gravity 0.993 kg/L dari total volume 10 KL. HFO yang disuplai saat bunker dengan specific gravity 0.925 kg/L. Studi yang dilakukan mendapatkan hasil gravity disc yang sesuai untuk HFO dengan specific gravity 0.993, 0.975 dan 0.925 kg/L berturut-turut 66, 75 dan 78 mm. Temperatur pemanasan 80 dan 90OC tidak mempengaruhi ukuran gravity disc. Kinerja purifier dapat ditingkatkan dengan mencegah overflow melalui penentuan gravity disc yang sesuai.

Abstract

Fresh onboard water is required to fulfill the crew's living needs and support the ship's operations. The need for fresh water for the crew and operational support of the boat is fulfilled with fresh water purchased from the land. Water purchases can be made when the ship is in port, either when the ship is at the dock or when the boat is anchored. Additional fresh water supply can be obtained continuously while the ship is sailing. Seawater desalination is a solution to produce fresh water to fulfill the new water needs. Desalination using a freshwater generator (FWG) involves evaporation and condensation processes affected by vacuum and operating temperature. This study was conducted to determine the effect of changes in pressure and temperature parameters on the production capacity of the freshwater generator. The study was conducted using a case study method through observation, and experimentation on board MT.PM REGENT. The vacuum in the FWG chamber was varied based on the suction of the vacuum ejector. Hot water temperature as a heater in the evaporator is taken from the cooling jacket of the main engine. The result of the pump ejector pressure variation greatly affects the vacuum level of the distillation chamber At pump ejector pressures between 8 – 16 Bar, the vacuum rate can reach 99 – 100% after the pump is operated At pressures of 2 and 4 Bar, the vacuum level drops dramatically, reaching only 50 and 80 %, respectively. The lowest production of FWG when operated with 80% vacuum with a heating temperature of 75 OC is 2767 liters/day. In FWG operation with a maximum vacuum of 100% and a heating temperature of 85 OC, it is able to produce the most fresh water around 6879 liters/day. Based on the changes in parameters, it can be concluded that a decrease in the level of vacuum and heater temperature reduces the production of fresh water from the Fresh Water Generator.

Abstract

The paper is The performance of water distribution in buildings is strongly influenced by the relative position of the reservoir and the outlet pipe. This represents an important technology transfer for enhancing building services engineering. This study examines the performance of a hydrophore system under variations in pipe height, water level, and tank pressure. Experiments were conducted using pipe heights of 1, 2, and 3 meters; water levels of ¼, ½, and ¾ of the tank capacity; and tank pressures of 1, 2, and 3 bar. Pressure adjustments were made by adding or releasing compressed air. System performance was evaluated by measuring the mass flow rate through one, two, and three outlet pipes operated individually and simultaneously. The highest mass flow rate for a single outlet pipe was achieved at a ½ water level and 3 bar pressure, yielding 67.87 kg/min through outlet pipe 2. For two outlet pipes, the maximum values were obtained at a ¼ water level and 3 bar, producing 72.75 and 73.25 kg/min. With all three outlets open, the highest flow rate reached 79.69 kg/min at a ½ water level and 3 bar. Overall, water level, tank pressure, pipe height, and the number of open outlets significantly affect distribution performance and must be considered in system design for multi-level buildings

Abstract

The extensive use of split-air conditioning in tropical countries raises environmental concerns because of the high global warming potential of R32 refrigerant. The hydrocarbon refrigerant R290 offers a promising alternative with a very low gross pollutant content (less than 4) and a near-zero ozone depletion potential. However, its flammability and impact on performance at reduced charge densities require further investigation. This study assesses the energy efficiency ratio (EER) of 1 PK split AC retrofitted with 40% charge weight from R32 to R290. The experimental tests were carried out under five operating conditions with room temperature of 23-27 degrees Celsius and ambient temperature of 30-35 degrees Celsius. System parameters including pressures, temperatures, compressor power consumption and the flow rate of the refrigerant were measured. The software REPROP was used for the thermodynamic analysis and the EER calculation. The results show that R32 achieves a higher EER (24.59-26.35 Btu per kWh) than R290 (15.33-17.21 Btu per kWh), resulting in a reduction of efficiency of 30-45 percent. Although R290 showed lower power consumption (0.446-0.476 kW compared to 0.76-0.82 kW in R32), the reduced mass flow rate reduced the cooling capacity. The study concluded that the 40 percent R290 retrofit reduces energy consumption but compromises energy efficiency, which requires further research on optimised weight and system components.

Abstract

Abstract and The Community Service Program (PKM) implemented by lecturers from the Indonesian State Maritime Polytechnic in partnership with the Karang Taruna Youth Association of RW 03, Genuk Village, Semarang Regency, aims to strengthen the capacity of youth organizations to improve social welfare. As a forum for the younger generation, Karang Taruna often faces issues related to governance, low social participation, and limited productive skills. The PKM implementation method employs a problem-based approach through the stages of survey, situation analysis, solution formulation, training, and evaluation. Key activities include training in organizational governance, character building through moral values, Sinoman, and Pranoto Coro, as well as vocational skills in electric welding. The results of the activities showed significant improvements across various aspects: organizational governance increased from 30% to 85%, social awareness of mutual cooperation rose from 40% to 90%, pranoto coro skills reached 70%, electrical welding skills reached 75%, active member participation rose from 25% to 80%, and initiatives for productive activities increased from 5% to 65%. These findings confirm that the PKM program serves not only as a knowledge transfer initiative but also as a catalyst for social and economic change. The provision of technical skills opens opportunities for productive enterprises, while the reinforcement of cultural values strengthens social solidarity. Thus, this PKM program contributes to strengthening the strategic role of Karang Taruna as a driving force for social development, while also underscoring the importance of collaboration between higher education institutions and the community in advancing Indonesia’s vision for 2045.
