Industrial waste in Depok still a problem raised because its contents were not following the government’s quality standards. Contaminants were considered pollutant are Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Suspended Solids (TSS) were quite high. One of these wastes was tofu wastewater which produced a foul odor and pollutes the environment when discharged directly into water bodies. Lack of industrial owners' education of the economic value of the waste caused direct disposal without being utilized first. Therefore, this Community Service activity aims to determine the feasibility of tofu industrial wastewater as a Spirulina sp. culture medium and provided education to the tofu factory owners, to utilize their liquid waste. In the implementation several stages are carried out, namely literature studies, sampling, implementing wastewater assessments, counseling also training. The result of this activity is tofu industrial wastewater can be utilized as a medium for cultivating Spirulina sp. which added economic value while reducing the environmental pollution. This can be seen from the results of Spirulina cultivation on the 10th day where the Optical Density (OD) continues to increase and harvested for further use.

The continues dynamics as the object of observation in studying the milestones that any company or industry should consistently achieve in long-term growth expected to be stable. The same applies to the natural gas distribution sector or known as city gas. The movement of data from year to year continues to depict an increasing trend with regard to the city gas sector in Indonesia. The objective of this particular study is to provide a better understanding of the city gas distribution sector in Indonesia and to provide a clearer picture of a number of latent variables that must be accommodated to optimize the distribution of natural gas to cities in Indonesia. The methodology used in this study is the Structured Equation Method (SEM). In a more specific description, path analysis developed from multivariate regression is used to analyze the correlation between indicators and latent variables so as to determine the validity of the multiple regression model. Still related to the research method, by sorting the data collection released from the Indonesian Central Statistics Agency and grouping data from indicators of city gas distribution companies during the period 2010-2020 divided into income, number of workers, wages, the volume of city gas distributed, and costs associated with operations. The results of this work are to provide input to the authorities and other stakeholders in order to optimize the growth of Indonesia's gas distribution sector. The value or originality of this study is to reveal the impact of latent variables that have the status of moderating variables. Study limitations - Due to the inaccessibility of non-disclosure primary data and limited data availability, it is assumed that the data obtained from the Indonesian Central Statistics Agency is valid to describe the explanatory variables of the city gas distribution sector in Indonesia.

In oil, gas, and geothermal drilling activities, the casing cementing process is always carried out in order to fulfill its function properly and safely. Therefore, everything that supports these activities must be carefully thought out. Before the actual cementing process is applied in the oil, gas, and geothermal field, laboratory-scale simulation must first be carried out by conducting experiments and testing several formulations of cement, water mixture, and additives to be used. The author chooses thixotropic additives, besides functioning as an accelerator, thixotropic can also strengthen the cement itself. With a number of experiments, an optimal cement slurry composition formulation will be obtained, in the sense that by using as few additives as possible, the requirements of the physical characteristics will meet the required standards for conditions (temperature and pressure) of the formation in the well to be cemented. All cementing activities are expected to run well, smoothly, and on time.
