The cost of biodiesel production process is still a challenge, it needs to explore any raw material which is economically inexpensive and effective technologies to overcome the problem. CPO off grade is deemed economically potential to be processed into biodiesel because its inexpensive cost . Membrane reactor is an alternative technology that need to be developed to address this challenge . The research aimed to study the effect of oil to methanol mole ratio and transmembrane pressure on biodiesel production from CPO Off Grade . The study was conducted using two- step process , namely the process of esterification and transesterification process . Esterification process was carried out with variation of oil to methanol mole ratio of 1:12. The amount acid catalyst used is 2 % by weight of oil and reaction time of 2 hours . Transesterification process is carried out on membrane reactor with variation of oil to methanol mole ratio of 1:12 , 1:16 and 1:20 and transmembrane pressure of 1 bar , 1.5 bar , 2 bars and a catalyst concentration of 1 wt% base oil and process temperature of 60 º C. The results showed the highest conversion reached 80.14 % at the mole ratio of 1:20 and transmembrane pressure of 2 bar Keywords : Biodiesel, CPO Off Grade, Membrane Reactor, Mole ratio, Transmembran Pressure.

National education aims to develop the potential of students to become individuals who are faithful, devout, have noble character, knowledge and creativity. In this digital era, teachers are required to be innovative, especially in utilizing learning media such as e-modules. At SMP Negeri 6 Sukabumi City, it was found that students had difficulty learning football material and needed additional interactive learning resources, such as flipbook-based e-modules. This research aims to develop, test the validity and measure the practicality of a soccer e-module, as well as observe its impact on student learning motivation. The method used is Research and Development (R&D) with the ADDIE model, which includes the Analyze, Design, Develop, Implement and Evaluate stages. The research was conducted at SMP Negeri 6 Sukabumi City involving 35 class IX students. Data was collected through observation, interviews, questionnaires and documentation. The research results show that the football e-module developed has been assessed as very valid with a percentage of 85% from material experts, 85% from learning experts, and 82.5% from media experts. This e-module is also practical to use in learning, with an increase in practicality from 71% in the first meeting to 80% in the second meeting. This flipbook e-module has proven to be effective in supporting PJOK learning, especially regarding soccer material.

The global financial crisis that occurred in 2008 had a significant impact on the Indonesian economy. To face these challenges, Bank Indonesia has implemented various monetary and macroprudential policies aimed at maintaining the stability of the financial system and national economy. These policies include adjusting benchmark interest rates, strengthening foreign exchange reserves, controlling inflation, and implementing macroprudential policies that focus on managing systemic risk.In an effort to maintain the stability of the rupiah exchange rate, Bank Indonesia has intervened in the foreign exchange market and increased foreign exchange reserves. Apart from that, Bank Indonesia also strives to keep inflation at a low and stable level through controlling liquidity and implementing appropriate monetary policy. To overcome systemic risks, Bank Indonesia has implemented macroprudential policies which include strengthening banking regulations, supervision of non-bank financial institutions, and increasing coordination with the government and related authorities.The success of Bank Indonesia's policies in dealing with the global financial crisis has helped maintain the stability of the Indonesian financial system and economy. However, new challenges continue to emerge, so Bank Indonesia needs to continue to make adjustments and evaluate policies on an ongoing basis to ensure financial system resilience and sustainable economic growth.

This study aims to analyze the level of basic futsal technical skills, including dribbling, passing, and shooting, among players at the Deco Futsal Club in Sukabumi Regency. The background of this study is based on the importance of mastering basic techniques in determining game effectiveness and team achievement. Basic techniques such as dribbling, passing, and shooting are fundamental elements that influence the overall quality of the game. This study used a descriptive quantitative method with a survey approach through skills tests on 20 players. Each player was tested on their abilities in these three basic technical aspects and the results were analyzed to determine their respective skill level categories. The results showed that the majority of players were in the sufficient category for all three techniques tested. Among the three, passing skills showed relatively better results compared to dribbling and shooting. This finding indicates that although passing skills are quite good, there is a need to improve the quality of the players' dribbling and shooting. Based on these conditions, this study recommends the need for a more focused and structured basic technique training program. Coaches are expected to design training sessions that focus on improving speed and control in dribbling, accuracy in passing, and accuracy in shooting. The practical implication of this research is the need for regular evaluation of players' basic technical abilities to monitor skill development. Thus, it is hoped that the quality of play and the achievements of the Deco Futsal Club can be significantly improved by strengthening the technical aspects of individual players.
