French wine exports to Japan exemplify international relations that blend Western and Eastern cultures. France's prominence as a grape cultivation center has attracted consumers worldwide, including those in Japan. However, the distribution of French wine to Japan often encounters obstacles and challenges, such as high import duties, strict regulations, and complex distribution networks. To address these issues, the Economic Partnership Agreement (EPA) was established, encompassing various provisions to liberalize trade and resolve both tariff and non-tariff barriers. On February 1, 2019, the EPA officially went into effect. This research was conducted using qualitative methods and data collection techniques, primarily through literature studies and official documents from European Union and Japanese government websites. The documents used as references in this research are official documents related to the EPA. This study applies a liberalism perspective, presented in a descriptive and explanatory manner at the nation-state level of analysis, with France as the unit of analysis. The EPA agreement between the European Union and Japan has proven to have a positive impact on French wine exports to Japan in 2018 - 2021. The result is that since the implementation of the EPA and the elimination of tariffs, there has been a decrease of – 11.45% in 2020 due to Covid-19 and the highest increase of 16 .15% in 2021.

ABSTRAKDalam sistem sumber daya hibrida, strategi manajemen energi (EMS) pada dasarnya hanya mengatur pembagian daya tanpa mempertimbangkan optimalisasi kinerja sistem. Oleh karena itu pada penelitian ini dirancang EMS berbasis optimasi pada kereta hibrida dengan sumber daya fuel cell (FC), baterai dan superkapasitor dengan metode External Energy Maximization Strategy (EEMS). Strategi ini dirancang untuk memaksimalkan energi yang disuplai oleh baterai dan superkapasitor melalui state of charge (SOC) baterai dan tegangan DC bus sehingga dapat meminimalisasi konsumsi hidrogen dan meningkatkan efisiensi keseluruhan sistem. Hasil simulasi memperlihatkan bahwa strategi ini mampu memaksimalkan kinerja baterai dan superkapasitor. Efisiensi sistem berhasil ditingkatkan menjadi 86,37% dan konsumsi hidrogen berhasil dikurangi 10% dari strategi pembandingnya. State of charge (SOC) baterai juga mampu dipertahankan untuk tetap dalam rentang batas yang telah ditentukan.Kata kunci: EMS, kereta hibrida, fuel cell, baterai, superkapasitor, optimasiÂ ABSTRACTThe energy management strategy (EMS) in a hybrid system essentially only regulates power sharing without considering system performance optimization. This study developed an EMS based on the optimization of hybrid train with fuel cell (FC), battery, and supercapacitor power sources using the External Energy Maximization Strategy (EEMS). This strategy is intended to maximize the energy supplied by battery and supercapacitor through the SOC of the battery and DC bus voltage, thereby reducing hydrogen consumption and increasing overall system efficiency. The simulation results show that this strategy can maximize battery and supercapacitor. The system efficiency was successfully increased to 86.37%, and the hydrogen consumption was reduced by 10% when compared to the comparison strategy. The SOC of the battery can also be kept within a certain range.Keywords: EMS, hybrid train, fuel cell, battery, supercapasitor, optimization

Hospitals are health care facilities that produce liquid, solid and B3 waste. The high pollutant load of hospital wastewater in Indonesia causes problems for the environment and other living things. Appropriate technology requires high costs (high cost) in manufacture and maintenance, this is one of the factors that hospitals are reluctant to make WWTP according to standards. This study aims to design a simple WWTP using a Moving Bed Biofilm Reactor (MBBR) and determine the reduction efficiency of hospital wastewater. The number of samples used in this study were 3 samples. WWTP tubs are made of PVC pipes with a total of 5 tanks, namely oil/fat separator tanks, equalization tanks, anoxic tanks, aeration tanks and sedimentation tanks. The efficiency of reducing the quality of hospital wastewater using MBBR is at an average concentration of pH of 9%, TSS of 43%, COD of 31%, BOD5 of 29% and Ammonia of 25%. The results of the influent and effluent differences test in hospital wastewater using SPSS software showed that only the concentrations of COD, BOD5 and Ammonia were significantly different, while there were no significant differences in the concentrations of pH and TSS. From the results of research from three government hospitals and private hospitals in Banten Province, it shows that the liquid waste processing system using MBBR can be successful in reducing waste characteristics.
