Hazard Analysis Critical Control Point (HACCP) ia a quality control system from the preparation of raw maerials to the product and accepted by consumers. HACCP is a requirement for guaranteeing the safety of food products produced according to company quality standards.PT. X produces packaged coconut milk as one of the main products and has implemented HACCP in every production process of its products. The packaged coconut milk that is produced often gets bloated in the finished product warehouse before the product is distributed. Therefore it is necessary to analyze the application of HACCP in the production of packaged coconut milk. HACCP application in the packaged coconut milk production process has set 4 Critical control points. CCP 1 (UHT Sterilization System & Aseptic Tank), CCP 2 (Filtration 500 micron), CCP 3 (Product Sterilization at 140-148ºC) and CCP 4 (Filling with Astepo Filler Filling Machine). Each Critical Control Point has physical and biological hazards, which must be controlled to ensure food safety. The research objective was to analyze the implementation of HACCP plan for coconut milk products based on SNI No. 01-4852-1998 regarding the HACCP system and analyzing the causes of product defects (bloating) in the determination of the CCP. Based on the analysis of HACCP application and the causes of product defects in packaged coconut milk, product defects due to bloating are not defects in the production process but defects caused by cross-contamination of microbes after filling. Cross contamination occurs due to cracks in the neck of the aseptic bag cup that cannot be detected directly, and the use of tools that should not be used during the filling process.

The increase in household electrical energy causes shrinkage of energy so that efforts are needed to conserve energy, especially electrical energy. One attempt to reducing the scarcity of electrical energy is by changing behavior. Changes in the behavior of electricity consumption can be influenced by psychological factors (norms, awareness, etc.), demographic factors (age, gender, income, etc.), and other factors such as regulations or policies from the government to conserve energy. This study seeks to determine the effect of psychological and regulatory factors on the behavior of household electricity consumption based on age. The method used was to conduct a survey by distributing questionnaires, the respondents obtained were 808 respondents. The results of the questionnaire were processed using the Structural Equation Model Partial Least Square (SEM-PLS) using the Smart-PLS software. The results of this study indicate that psychological and regulatory factors can explain their effect on the behavior of electrical energy consumption for ages <30 years of 50.9%. For 30-50 years old it is 49.5% while those> 50 years old are 59.3% and the rest is explained by other factors / variables outside those that have been studied so that it can be concluded that psychological factors and regulatory factors have a significant and significant influence. positive behavior towards household electrical energy consumption at all ages. it is expected that the results of this study can become the basis for making stronger regulations or policies in the field of energy conservation.

The rapid development of the palm oil industry, which cannot be denied, has an impact on the amount of industrial waste, particularly wastewater, requiring proper and effective treatment to reduce the impact of the damage. Wastewater treatment of Palm Oil Mill Effluent (POME) in an aerobic pond requires an adequate supply of oxygen so that its quality improves and becomes disposable, so it requires assistance from aeration media. A fine bubble diffuser was used as the aeration medium in this study. The aeration medium in this study was a fine bubble diffuser. The purpose of this research is to investigate the impact of installing a diffuser on the quality of the final wastewater, particularly the COD and BOD values, in the palm oil industry wastewater treatment. The analysis results for the wastewater parameters after the installation of the fine bubble diffuser revealed a significant reduction in the waste's COD and BOD values to 130 – 175 mg/L and 67 – 78 mg/L, respectively, making it more suitable for disposal to the environment.

The oil palm empty fruit bunch (OPEFB) as solid biomass of palm oil mill industry is available in abundance and has the potential to be utilized as the raw material of nanocrystalline cellulose (NCC). This research aims to investigate the effect of bioprocess treatment (bio-delignification, bio-bleaching, and enzymatic hydrolysis) on the nanocrystalline cellulose synthesized from OPEFB. The bio-delignification of OPEFB fiber was carried out using white-rot fungi (Tremetes versicolor and pre-bleaching pulp with xylanase. Trichoderma reesei, a cellulase enzyme type was used to hydrolyze the OPEFB fiber into nano-sized cellulose. The result exhibits that the cellulose content of OPEFB pulp using bio-delignification increased significantly compared to chemical treatment. Furthermore, the concentration of enzyme and hydrolysis time in the synthesis treatment affect reducing average particle size and increasing the crystallinity index while decreasing the yield of NCC produced. The synthesis process was under optimal processing conditions at 1% enzyme concentration and 3 days of hydrolysis time resulting in the NCC product with 155 nm of average particle size, 66.78% of crystallinity index, and a yield of 38.28%. The bioprocess technology applied in this study could improve the cellulose yield of OPEFB and enhance the quality parameters of NCC products such as particle size and crystallinity index.
