Increased energy consumption can lead to depletion of fossil energy reserves that can pose a threat to energy supply in Indonesia. One way to increase the intensity of energy savings is to make changes in consumer behavior. The development of gender roles, abilities, and attention led most researchers to argue that women are more consistent in attention to environmental change than men. Women are more concerned with environmental quality and participate in environmental activities. Thus, this research tries to determine the influence of psychological factors on the behavior of household electrical energy consumption in term of gender differences. This study used questionnaires distributed using Google Docs to household electrical respondents several in Indonesia. Referring to ABC (Antecedents-Behaviour-Consequences) model of consumer behavior, the total of 808, questionnaires from 526 male respondents and 282 female respondents were successfully collected. The data were processed by the Partial Least Square Equation Modeling Model (SEM-PLS) using Smart-PLS software. The study concluded that,if given the consequences, women have higher influence to the behavior of electrical energy consumption than men. Overall psychological factors have a positive and significant influence on the behavior of electric energy consumption in Indonesia.
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.
We are currently faced with the problem of the Covid 19 pandemic and no cure has been found. One of the efforts made by the community is to implement health protocols to the recommendations from the government and increase the body's resistance to prevent this Covid 19 attack. Indonesia has a wealth of spices that are quite large in number and type. According to some studies that this spice can increase the body's resistance because it contains antioxidants and active compounds that can ward off free radicals. This is one of the business opportunities as well as an effort to increase the body's endurance if consumed. Community service activities organized by ATI Padang Polytechnic, Agro Industry Engineering Study Program aims to provide technology for processing instant spice drinks based on red ginger. The spices used are red ginger, cinnamon, cloves and lemongrass. The product produced is instant red ginger. Partners of this activity are UKM/communities in Bungo Pasang Subdistrict, Koto Tangah District, Padang. The method used is to deliver processing technology through virtual training and practice independently. After attending virtual training and independent practice using equipment and materials that have been assisted by team, participants submitted their products that have been packaged as evaluation materials. It is hoped that with this activity, UKM/communities can produce this product in order to increase the resilience of the family as well as their business choice. The processing of spices into instant beverage products is expected to be widely marketed, more durable and provide added value to spice commodities.

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.
A new technology has been currently developed for the removal of heavy metal waste in water, called biosorption. Biosorption technology has been widely used to remove heavy metals from liquid waste. The potential biomass which can be used as bio sorbent was activated coconut husk waste. By using the continuous flow method and activated coconut husk as bio sorbent, the obtained optimum flow rate and bed height of bio sorbent were 2 mL/min and 0.1 g with adsorption capacity of 188.322 mg/g.
