Social media has proven to be quite effective in raising awareness and anti-corruption movements in society. This research aimed to analyze the use of social media Twitter as a means of the Corruption Eradication Commission (KPK) in conducting anti-corruption campaigns in Indonesia. The research employed a qualitative content analysis on the KPK's official Twitter account. The data were processed using the NVIVO 12 Plus software to answer research questions. This research revealed that the KPK's Twitter account is quite active in carrying out anti-corruption campaign activities, although in general it is not optimal. It can be seen from the low intensity of communication and limited communication network so that it is considered as less collaborative. Improving the problems is needed by KPK as it must also show good performance so that public trust continues in high condition. However, this research has limitations in looking at all anti-corruption campaigns carried out by the KPK because it only used Twitter as the reference. Therefore, further research is suggested to analyze all KPK social media such as Youtube and Instagram.

The purpose of this study is to examine how Information and Communication Technology (ICT) affects village development performance, which is measured through the Developing Village Index (VDP). This index is made up of three dimensions: Social, Economic, and Environmental Resilience Indexes. By using quantitative methods and cross-sectional data from 1,842 villages in the Central Sulawesi Province in 2021, the study concludes that ICT has a positive impact on the development performance of villages overall. The study found that the quality of internet signals and the number of cell phone users, as well as the presence of technology devices and internet facilities in village offices, have a positive influence on village development performance. However, the existence of internet facilities for the public has no effect on village development performance, including economic, social, and environmental development in rural areas. By examining the effectiveness of both the community and the village government's utilization of ICT, this study contributes to understanding the impact of ICT in improving village development performance. To reduce the digital divide and continue to support rural development, it is important to enhance ICT facilities and infrastructure for rural communities and improve the quality of their implementation governance. Furthermore, to support the delivery of public services and the implementation of village development programs, both the government and Regional Government need to encourage the effectiveness of the use of ICT.

With an ongoing progress in industries and technologies, most firms and businesses highly depend on cooperation and collaborations within a supply chain. In today’s competitive business environment, customer satisfaction plays an important role for the business survival. These matters can be secured by “supply chain”, a chain consists of various companies working together to maintain customers’ satisfaction. If various stages of different chains cooperate with each other, “supply chain network” (SCN) will be the outcome. In order to have a supply chain network or just a supply chain-operation in its best possible way, some optimization techniques are needed. In this paper, we present a close look at previous studies in the field of SCN optimization techniques and classify them based on the relative important characteristics.
