Community Approaches to Total Sanitation (CATS) programmes, like the Sanitasi Total Berbasis Masyarakat (STBM) programme of the Government of Indonesia, have played a significant role in reducing open defecation though still little is known about the sustainability of the outcomes. We assessed the sustainability of verified Open Defecation Free (ODF) villages and explored the association between slippage occurrence and the strength of social norms through a government conducted cross-sectional data collection in rural Indonesia. The study surveyed 587 households and held focus group discussions (FGDs) in six ODF villages two years after the government’s ODF verification. Overall, the slippage rate (i.e., a combination of sub-optimal use of a latrine and open defecation at respondent level) was estimated to be 14.5% (95% CI 11.6–17.3). Results of multivariate logistic regression analyses indicated that (1) weaker social norms, as measured by respondents’ perceptions around latrine ownership coverage in their community, (2) a lack of all-year round water access, and (3) wealth levels (i.e., not being in the richest quintile), were found to be significantly associated with slippage occurrence. These findings, together with qualitative analysis, concluded that CATS programmes, including a combination of demand creation, removal of perceived constraints through community support mechanisms, and continued encouragement to pursue higher levels of services with post-ODF follow-up, could stabilize social norms and help to sustain longer-term latrine usage in study communities. Further investigation and at a larger scale, would be important to strengthen these findings.

Opinions about the government’s response to forest fires have drawn many opinions from the community. One way for people to express their opinions is to use social media Twitter. This study conducted a sentiment analysis process on the government’s response to handling forest fires in Indonesia in 2019 with data sources from Twitter. The analysis was carried out on 6325 datasets written on Twitter on September 20, 2019, and then through the process of pre-processing, automating labeling and classification. The automate labeling process uses a Vader that automatically detects the negative or positive polarity of each data and then goes through the classification process using the KNN algorithm. The test results that were built using rapidminer tools showed an accuracy level of the KNN algorithm of 79.45%, the highest if compared to other classifier algorithms such as decision trees, naïve Bayes and random forests. The sentiment analysis process can almost run automatically without human touch because there is already automated labeling using Vader. Testing sentiment analysis related to the government’s response to forest fires can be analyzed using the KNN algorithm and lexicon polarity detection Vader can be done properly.

The purpose of this study was to analyze the application of e-government through Samsat Mobile Jawa Barat at the Regional Revenue Agency of West Java Province. The theory used in this study uses e-government theory which includes (1) content development, (2) competency building, (3) connectivity, (4) cyber law, (5) citizen interface, and (6) capital. The research approach used is a qualitative approach. Data collection techniques by interview, observation and documentation. The data analysis technique is based on Creswell's thinking with a bottom-up hierarchical approach model. The results of this study indicate that the implementation of e-government through Samsat Mobile Jawa Barat in the Regional Revenue Agency of West Java Province has been running quite well. Although based on Idrajati's e-government theory, there are several criteria that need to be improved. Such as content development criteria that still do not provide an iOS-based Samsat Mobile Jawa Barat application, competency building criteria have not yet produced employees who are experts in managing the appearance of the Bapenda West Java website design and content. The connectivity criteria are good because they are in the West Java region. Cyber law criteria must be added specifically, because it only follows the rules of the central government, the citizen interface criteria still need to be developed because it only has two channels, namely the website and the android application. While the criteria for capital is sufficient, it only needs additional sources of capital apart from the APBD.

Partners realize that the production of cultivated fish can still be increased, one of which is by monitoring water quality by providing aeration to maintain water health. Partners need a technological assistance that can improve the quality of results and production levels in a shorter time, and of course not incur large electricity costs from using this technology. This community service program activity is designed to solve partner problems. The proposal team provided a technology product called E-Ox Level, a proven technology to monitor pond water quality and control the aerator engine to keep it at optimum water quality standards. This technology is energy efficient, because it utilizes solar energy. This product can reduce operating costs and increase production yields. This program shows positive results. The results of its installation in the Budikdamber pond showed that the growth rate of fish length and weight was faster than the pond without the help of technology, and the mortality rate was recorded to be lower. These results are similar when the technological device is applied to larger biofloc ponds.
