Abstract
Ketersediaan air bersih merupakan kebutuhan vital bagi masyarakat maupun operasional pelayaran, sehingga diperlukan teknologi pengolahan air yang efisien dan dapat diandalkan. reverse Osmosis (RO) menjadi salah satu solusi yang efektif untuk mengubah air payau atau air laut menjadi air yang dapat digunakan untuk kebutuhan sehari hari . Namun, sistem RO membutuhkan suplai energi listrik yang stabil, sementara pada beberapa wilayah pesisir ketersediaan listrik masih terbatas. Pemanfaatan panel surya sebagai sumber energi alternatif menjadi pilihan menarik karena sifatnya terbarukan, namun efisiensi panel surya menurun signifikan ketika suhu modul meningkat akibat paparan radiasi matahari. Penelitian ini mengusulkan integrasi panel surya berpendingin dengan sistem RO untuk meningkatkan produksi air bersih. Pendinginan panel dilakukan melalui pipa tembaga pendingin dengan fluida air pada permukaan panel surya guna menurunkan suhu operasional, sehingga daya listrik keluaran meningkat. Air hasil pendinginan yang mengalami peningkatan temperatur kemudian dimanfaatkan sebagai air umpan RO,kemudian hasil dari pendinginan tersebut diharapkan dapat meningkatkan produktivitas energi Listrik yang digunakan sebagai suplai energi utama sistem reverse osmosis,serta untuk mencapai energy balance yakni energi yang dibutuhkan untuk mengolah air bersih pada sistem reverse osmosis Penelitian ini bertujuan (1) mengetahui peningkatan performa panel surya berpendingin dalam menghasilkan listrik berdasarkan kondisi intensitas cahaya matahari serta suhu operasi , (2)Pengaruh suhu air umpan terhadap produktivitas air permeate (3) mengetahui nilai specific energy consumption pada sisrem reverse osmosis yang diintegrasikan dengan panel dalam memproduksi air permeate (4) mengetahui keseimbangan energy atau energy balance antara integrasi kedua sistem panel surya dengan sistem reverse osmosis,(5) mengetahui kapasitas sistem sumber energi yang dibutuhkan agar integrasi sistem reverse osmosis dan panel surya dapat beroperasi secara optimal. Hasil penelitian menyatakan peningkatan produktivitas daya Listrik pada panel yang menggunakan pendingin yang memanfaatkan air brine dari sistem reverse osmosis mampu meningkatkan efisiensi produksi Listrik sebesar 3,9% dibandingkan panel dengan non pendingin,pendinginan panel tersebut juga menyebabkan kenaikan suhu pada air umpan hingga 30 C° hingga 40 C°,suhu air tersebut memberikan efek pada specific energy consumption reverse osmosis semakin tinggi suhu semakin rendah nilai Specific energy consumption dan juga berpengaruh terhadap recovery rate membrane Dimana pada suhu air paling rendah 30 C° menghasilkan persentase recovery rate 16,67% dan recovery rate pada suhu 40 C° 15,38% penurunan recovery rate diakibatkan pada suhu air umpan yang mempengaruhu pori pori membrane sehingga air bersih lebih sedikit diproduksi ketika suhu air umpan yang lebih tinggi,kemudian pada nilai energy balance antara reverse osmosis dengan panel surya perlu penambahan produktivitas Listrik untuk memenuhi kebutuhan Listrik sistem desalinasi air reverse osmosis selama seharian kemudian didapatkan proyeksi panel surya berjumlah 9 unit panel 200 WP dan 2 buah batterai 100 ampere hour untuk memenuhu kebutuhan Listrik sistem reverse osmosis

The availability of clean water is a fundamental necessity for both communities and maritime operations. Therefore, an efficient and reliable water treatment technology is essential. Reverse Osmosis (RO) is one of the most effective technologies for converting brackish water or seawater into water suitable for daily use. However, RO systems require a stable electrical power supply, while access to electricity remains limited in many coastal areas. The utilization of photovoltaic (PV) solar panels as an alternative renewable energy source is a promising solution. Nevertheless, the efficiency of PV panels decreases significantly as the module temperature increases due to prolonged exposure to solar radiation. This study proposes the integration of a cooled photovoltaic (PV) system with a Reverse Osmosis (RO) system to enhance clean water production. The PV panel is cooled using a copper pipe cooling system with water as the cooling fluid to reduce the panel's operating temperature, thereby increasing its electrical power output. The heated cooling water is subsequently utilized as the RO feed water. This integrated approach is expected to improve the electrical energy productivity of the PV system, which serves as the primary power source for the RO unit, while also achieving an energy balance between the electrical energy generated and the energy required for freshwater production. The objectives of this study are: (1) to evaluate the performance improvement of the cooled PV panel in generating electrical power under varying solar irradiance and operating temperature conditions; (2) to investigate the effect of feed water temperature on permeate water production; (3) to determine the Specific Energy Consumption (SEC) of the integrated Reverse Osmosis system in producing permeate water; (4) to analyze the energy balance between the integrated photovoltaic and Reverse Osmosis systems; and (5) to determine the required energy source capacity to ensure the optimal operation of the integrated PV–RO system. The results of this study are expected to demonstrate the improvement in photovoltaic energy efficiency through panel cooling as well as the enhancement of Reverse Osmosis productivity through the utilization of heated cooling water as feed water. Furthermore, the findings are expected to provide an integrated and sustainable solution for clean water supply in coastal areas with limited access to conventional electricity.The results of this study indicate that the photovoltaic (PV) panel equipped with a cooling system utilizing brine water from the Reverse Osmosis (RO) process achieved a 3.9% improvement in electrical power generation efficiency compared with the uncooled PV panel. The cooling process also increased the feed water temperature from approximately 30°C to 40°C before entering the RO system.The elevated feed water temperature had a significant effect on the Specific Energy Consumption (SEC) of the RO system. As the feed water temperature increased, the SEC decreased, indicating that less electrical energy was required to produce a unit volume of permeate. However, the increase in feed water temperature also affected the membrane recovery rate. At the lowest feed water temperature of 30°C, the RO system achieved a recovery rate of 16.67%, whereas at 40°C, the recovery rate decreased to 15.38%. This reduction is attributed to changes in membrane characteristics and transport behavior at higher temperatures, which resulted in a lower proportion of feed water being converted into permeate despite the reduction in energy consumption. Furthermore, the energy balance analysis between the photovoltaic system and the Reverse Osmosis unit showed that the electrical energy generated by the existing PV system was insufficient to satisfy the daily energy demand of the desalination process. Based on the projected daily energy requirement, the system would require approximately nine 200 Wp photovoltaic panels and two 100 Ah batteries to provide sufficient electrical energy for continuous operation of the Reverse Osmosis desalination system throughout the day
