Biogas is a mixture of gases formed from the decomposition of organic materials with the help of bacteria through an anaerobic fermentation process (airtight) to produce biogas in the form of methane gas (CH4) that can be managed. In biogas production, pH is one of the factors that affects the production process where an inappropriate pH will cause the performance of microorganisms in degrading organic matter into biogas to be less than optimal. This can be seen from the COD reduction produced, namely COD reduction will increase when operating conditions are at optimal pH, for this reason, conditioning the operating process according to the optimum pH is needed. So that in order to maximize the production of biogas produced, research was conducted to determine the optimum pH in the biogas production process carried out at PT AMP Plantation. In this study, biogas production data was collected so that the optimum pH in the production process carried out was known. From the research that has been carried out, the optimum pH for the biogas production process is 7, which produces the highest COD reduction of 91.78%.

Chronic Kidney Disease (CKD) is a clinical condition characterized by an irreversible decline in kidney function to a degree that requires permanent renal replacement therapy, in the form of dialysis or kidney transplantation. One of the clinical syndromes that occurs in kidney failure is uremia. This is caused by decreased kidney function. CKD disease will cause kidney function and role to continue to decline (progressive) and cannot return (irreversible) (Sherwood, 2016). This study aims to determine the effect of Murotal Al-Qur'an distraction therapy on reducing anxiety levels in CKD patients undergoing hemodialysis at Toto Kabila Regional Hospital. This research uses a quantitative research design with a Quasy Experimental research design involving an intervention group and a control group. The population in this study were all CKD patients undergoing hemodialysis at Toto Kabila Regional Hospital. The sample in this research consisted of 15 respondents, the data collection technique was making observations and using a questionnaire sheet. Based on the results of the analysis in the treatment group, the results showed that the level of moderate anxiety was 5 respondents (62.5%), and mild anxiety was 3 respondents (37.5%). In the control group, the results showed that the level of moderate anxiety was 5 respondents (71.4%), and the results of severe anxiety were 2 respondents (28.6%). The results of statistical tests in the treatment group obtained a P-value of 0.01 and in control group 0.03 which means <0.05 so it can be concluded that Ha is accepted which means there is an effect of Murotal Al-Quran Distraction Therapy on reducing anxiety levels in CKD patients undergoing hemodialysis at Toto Kabila Regional Hospital.

The processing of garden products, namely cassava as an effort to develop the community's economy and increase the creative economy of the Sumur Village community is one of the leading work programs of post 94 in completing the community service process. This community service activity is a form of training for the community in the implementation of cassava garden product processing in Sumur Village, Brangsong District, Kendal Regency. The factor that encouraged group 94 to process garden products in Sumur Village was the abundance of cassava plants that were not optimally utilized. So it needs to be optimized as a food ingredient that is ripe and ready to be. The implementation of the community service above also has a mission to create new innovations in the processing of garden products, namely cassava can be processed into cassava rengginang, cassava layer, cassava brownies, cassava dodol, mocaf flour, and cheese cendol (cheese cassava). The implementation of this community service uses a training method for the community whose majority livelihood is as a farmer. The stages carried out are starting preparations, namely recording data on residents who work as farmers and the availability of cassava harvests on the Plantation. Next, start the implementation stage by involving extension workers from the Kendal Regency UMKM Service to help provide processing training on the potential of cassava harvests from raw to cooked. This service aims to improve the creative economy through cassava processing training for the people of Sumur Village.

Personal Protective Equipment (PPE) is essential for worker safety, especially in oil palm harvesting activities. PT Langkat Nusantara Kepong faces major challenges related to work safety, with analysis showing that work accidents still occur frequently in the Padang Brahrang Plantation. This indicates the need for an in-depth evaluation of the use of Personal Protective Equipment (PPE) to reduce the risk of work accidents. By using the clustering method to group data based on the type of Personal Protective Equipment (PPE) used and aims to provide recommendations for optimizing the use of personal protective equipment based on risk management and reducing the incidence of work accidents. From testing the results of cluster 3, cluster 4 and cluster 5 it can be concluded that clustering with 5 clusters provides the most efficient and precise results, followed by 4 clusters, while 3 clusters provide greater variation within clusters, indicating that clustering with fewer clusters is less able to capture subtle differences in the data.

The Indonesian Sugar Plantation Research Center (P3GI) plays a crucial role in the development of the sugar industry in Indonesia. Currently, the contribution extends not only to the sugarcane industry but also begins to branch out into the field of education by providing educational tours for the public. The educational tourism activities at the Indonesian Sugar Plantation Research Center (P3GI) not only offer tours but also include accompaniment. The main objective of this accompaniment is to enhance tourists' knowledge by accompany and educating them during their visit to P3GI. Guides will take tourists through several educational spots, including the library, museum, explant area, garden, and plantation. After the tour, tourists are invited to taste natural sugarcane juice (STA). The outcomes of the educational tourism guidance activities at the Indonesian Sugar Plantation Research Center (P3GI) have beneficial effects for all parties involved, especially tourists.

The purpose of this research was to find out the Influence of the Composite of the Planting Media on the Growth of Angsana Plant and the composition of a good plant media for Angsana plantation. This research uses a single Design (DK) factor, with a medium dose treatment of M0 = Topsoil Each Polybag, M1 = Media 100 Gram Each Polybag, M2 = Media 200 Gram Each Polybag, M3 = Media 300 Gram Each Polybag. As a result, it will continue to be analyzed using the DMRT (Duncan Multiply Class Test) tasks 95% with the application of Statistics tools for Agriculture Research. The length of plant observation, for treatment with less control in each unit with a value of (A0) of 19.33cm, has no significant influence on the treatment of each unit. In addition to treatment (A1) 10 Treatment by (A3) 100.33cm and (A3) 40.33cm had a significant influence on treatment (A0) 19.33cm. of treatment A1, A3 and A2 showed that the influence of organic breastfeeding or animal waste on the supply of Angsana plants increased in length or height in each unit.
