Corrosion control on petroleum pipe wells can only be done through the addition of corrosion inhibitors. In this study, the corrosion inhibitors studied were sourced from marine microorganisms, namely the type of microalgae Tetraselmis chuii sp. The aim to be achieved in this study was to determine the mechanism and efficiency of inhibition of the extraction of microalgae biomass in corrosion of carbon steel in an environment of petroleum conditions. To achieve this goal, a potentiodynamic polarization method (Tafel extrapolation) was used and the Electrochemistry Impedance Spectroscopy (EIS) method used the galvanostat-potentiostat device (Voltalab 40, PGZ 301). The results obtained from this study indicate that API 5L X65 carbon steel in the petroleum environment is very significantly corroded, caused by acidic media derived from acetic acid and dissolved CO2. The inhibition ability of the Tetraselmis chuii sp. Biomass extract. in line with the increasing extraction concentration reaching optimum at a concentration of 250 ppm with inhibition efficiency reaching 70%. The mechanism of inhibition takes place through the formation of a protective layer adsorbed on the surface of carbon steel. The protective membrane formed is uneven and tends to be porous.

This study aims to examine and analyze and determine the implementation of local government policies in Bekasi Regency in alleviating community poverty (descriptive study in Cipayung Village, East Cikarang District). This research is a descriptive qualitative type with data collection techniques carried out using triangulation which includes interviews, observations and documentation studies, then the data is analyzed by reducing, presenting and drawing conclusions. The theory used is Edwards III's Policy Implementation in Putra (2001:9) in which there are four dimensions, namely nature, organizational structure, communication and resources. The results of this study indicate that the policies made by the Bekasi Regency Government have not gone well because the communication between the Regional Government Apparatus and the Cipayung Village Government has not been coordinated and has not been implemented and has not been implemented by the regional government in implementing poverty alleviation policies against the Bekasi Regency Regional Regulations. Number 10 of 2012 concerning the organizational structure has not yet created characteristics that are able to encourage Small and Medium Micro Business actors to develop better.

In carrying out bureaucratic reform, of course, it is necessary to have potential and competent government officials which are expected, with their presence, to create good governance. And, for the realization of all this, principles, principles and strategies must be applied by the government apparatus. Meanwhile, in reorganizing a bureaucracy, there are several models among which there are 3 (three) models, namely strengthening government regulations and policies, implementing e-government and e-governance, and collaborative governance.

This study discusses the Village Government Strategy in Overcoming the Spread of the Covid-19 Virus in Sukaluyu Village, Karawang Regency. The purpose of this study is to find out and examine what kind of strategy the Sukaluyu Village Government is implementing in tackling the spread of the Covid-19 virus. This study uses a qualitative method with a descriptive approach. The author uses data collection techniques in the form of literature studies, observations, interviews, and documentation studies. This study was analyzed using the Theory of Strategic Management which was bought by Fred R. David (2017:4) with three indicators namely, strategy formulation, strategy implementation and strategy evaluation. The results of the research regarding the Village Government's Strategy in Overcoming the Spread of the Covid-19 Virus in Sukaluyu Village, Karawang Regency have not run optimally starting from the stages of strategy formulation, strategy implementation and strategy evaluation. This is due to the absence of a written vision and mission and the absence of village regulations in handling Covid-19 made by the village government as a supporting initial capital in developing strategies. The dissemination of socialization on prevention of Covid-19 was uneven and irrational, and the evaluations carried out did not produce constructive changes.

The government continues to innovate in providing satisfactory public services. One of these innovations is SP4N-LAPOR!, a technology-based public complaint management system. Bekasi city is one of the regions that has implemented SP4N-LAPOR!, managed by the Communication, Informatics, Statistics, and Encryption Office (Diskominfostandi). This research aims to determine the effectiveness of the SP4N-LAPOR! application in Bekasi City using Budiani (2007) as cited in (Purnamawati et al., 2022) effectiveness theory, which includes four indicators: program targeting, program socialization, program objectives, and program monitoring. This research uses a descriptive qualitative method with data collection techniques through interviews, observation, and documentation. The results show that the effectiveness of SP4N-LAPOR! in Bekasi City is not yet fully optimal. This is due to lack of socialization by the local government, limited human resources. The conclusion of this study is that the use of SP4N-LAPOR! in Bekasi City is quite effective, but it still requires improvements in terms of socialization, evaluation, and technical support.

This research aims to analyze the role of Karawang Regency Government in encouraging collaborative action on the implementation of Karawang Regent Regulation Number 22 of 2021 concerning Reduction of Plastic Bags. The approach used is qualitatively descriptive with Emerson and Nabatchi's 2015 Collaborative Governance theory, with a focus on collaborative action dimensions. The data was collected through in-depth interviews with the Regional Apparatus Organization (OPD), business actors, environmental communities, and communities, as well as through documentation studies and field observations. Research results show that collaborative action has emerged in the form of socialization by local governments and education by environmental activists. However, this collaboration has not been strategic, unified, and has not touched the main target group evenly. Many business actors and the public are not aware of the existence of the regulation, which shows weak communication across sectors. Actions taken are more formal and not accompanied by participatory feedback mechanisms. This study concluded that collaborative efforts in policy implementation still need to be strengthened, both in terms of inclusion, sustainability of participation, and cross-sectoral strategy design. In this case, the local government needs to form a collaboration forum across actors to organize a more adaptive joint program and reach policy targets directly.
