Abstract

The disproportionate growth between the transportation fleet and the infrastructure causes congestion, pollution, inconvenience and poor service. However, the high growth in transportation fleets managed by the private sector more than those managed by the government is not effective, on the other hand the government does not have enough funds to provide adequate public transportation facilities, so the concept of Allocation Cheap Sourcing is needed which is a collaboration between fleets managed by the private sector and the government. The method used in this study is Evidence based policy . The results of the study show that the effectiveness of collaboration can be in the form of partnerships and new forms of organization (NFO).

Abstract

The State Polytechnic of Madura (POLTERA), located in Sampang Regency, East Java, was established in 2012. Its location outside the city of Sampang and directly on the coast means that the groundwater source at POLTERA is brackish. Meanwhile, the municipal water supply (PDAM) has not yet reached the coastal area. Consequently, to meet its clean water needs, POLTERA has been purchasing three tanks of clean water each day. This water supply is not intended to meet consumable needs.This research will analyze the daily clean water needs at POLTERA and design the pump and pipeline for a sea water reverse osmosis (SWRO) system. The outcome of this research is a plan for the SWRO pump and piping lines based on a case study at the POLTERA campus. The research found that the daily clean water requirement at POLTERA is 170.33 m³.The pump and piping system in the SWRO works by flowing brackish water from a well into a pretreatment tank. The water is then filtered in stages through a 5-micron sediment filter, a 1-micron sediment filter, and a Granular Active Carbon (GAC) filter to remove particles and harmful substances. It is then pumped at a pressure of 10–15 bar to meet the requirements of the RO process. Next, the water enters the RO membrane to produce fresh water, which is stored in a storage tank. The water then passes through a post-carbon filter to improve its smell and taste before finally being ready for consumption.

Abstract

Sistem perpipaan gas bertekanan tinggi pada fasilitas Floating Production Storage and Offloading (FPSO) merupakan komponen kritis yang memiliki risiko tinggi terhadap kebocoran dan ledakan yang dapat mengancam keselamatan awak kapal serta instalasi . Penelitian ini bertujuan untuk merancang sistem proteksi otomatis sebagai langkah preventif terhadap bahaya kebakaran dan kebocoran gas pada pipa discharge gas FPSO. Metode penelitian yang diterapkan adalah Research and Development (R&D) dengan mengintegrasikan sensor gas MQ-2 dan sensor api (flame sensor) berbasis mikrokontroler ESP32 sebagai pusat kendali . Sistem ini dirancang untuk melakukan pemantauan kondisi abnormal secara real-time dan memberikan respons mandiri melalui mekanisme fail-safe. Ketika kadar gas atau keberadaan api terdeteksi melebihi ambang batas aman, sistem secara otomatis memicu alarm buzzer, menyalakan indikator LED merah, dan mengaktifkan mekanisme shutdown dengan memutus aliran gas melalui solenoid valve. Hasil pengujian menunjukkan bahwa sistem mampu bekerja secara responsif dengan titik kritis shutdown otomatis pada kadar gas 415 PPM . Deteksi maksimal pada sensor gas tercapai pada jarak 5 cm dengan nilai 987 PPM (4,92 V), sementara sensor api menunjukkan kecepatan respons instan sebesar 0,52 detik pada jarak dekat. Meskipun analisis perhitungan menunjukkan nilai error sebesar 20% pada sensor gas akibat faktor hysteresis dan kondisi lingkungan terbuka, sistem secara keseluruhan memiliki tingkat keberhasilan fungsional sebesar 80% . Implementasi perangkat ini memiliki potensi besar sebagai solusi teknis untuk meningkatkan standar keselamatan kerja maritim dan mencegah kecelakaan kerja fatal pada instalasi pipa gas di lingkungan operasional kapal FPSO

Abstract

As an important means of sea transportation for the distribution of goods and human mobility between islands, ships require a reliable prime mover to avoid wear or damage, especially when overspeeding occurs which can result in fire. Therefore, a prototype was created that uses an IR Obstacle sensor to monitor the RPM speed of the rotating engine. By using Arduino Uno as a processor, this prototype is able to display the RPM value on the LCD and provide a signal in the form of a green light if the speed is below 4000 Rpm, as well as a red light and buzzer sound if overspeed occurs above 4000 Rpm, followed by the engine turning off after 15 seconds. Testing shows that this prototype has a high level of accuracy, with a difference between 0.08% to 2.73% and an average difference of 1.003%.

Abstract

The shipping industry faces challenges in reducing environmental impact and increasing operational efficiency. Among them are the expansion tanks on ship engines which play an important role in maintaining the pressure and water quality of the engine cooling system, which is still run manually on some ships. This can result in the risk of engine damage due to overheating or unstable pressure. Manual water filling that requires crew supervision can cause operational instability. This research designed a prototype of an automatic water filling system for expansion tanks, using microcontroller-based automation technology and an Internet of things system to make monitoring easier. This system aims to increase efficiency and reduce the risk of engine damage, thereby supporting the sustainability of ship operations in the future. In the trials that have been carried out, this tool is able to operate the expansion tank filling automatically and efficiently. The distance sensor used has high accuracy with a largest error of 1.6%, and an average error of 0.01%. Integration with the Internet of Things system can run well and reliably with 100% success and latency of 0.5 – 1 second. The system's overall success rate is 80%. So the system can be used in real working conditions
