The Corporate Social Responsibility (CSR) literature has advanced beyond its long-standing emphasis on a firm's financial performance to include its social impact. However, it has fallen short of offering insight into how effective CSR is in the event of a disaster. This study investigated the community's perception of CSR in wetland farmers communities after flood disasters. Data were from 49 farmer groups in South Kalimantan Province, Indonesia. The research hypotheses were drawn: Perceived benefits of CSR initiatives affect farming community resilience, farming community wellbeing, and perceived competence of wetland farmers; Community resilience affects community wellbeing; Community wellbeing and community resilience affect perceived competence of farmers. The structural equation modeling (SEM) analysis showed that CSR initiatives positively affected community resilience and community wellbeing but had no effect on the perceived competence of farmers; Community resilience had a positive effect on community wellbeing. However, both community wellbeing and resilience did not affect perceived competence. This study sheds light on the complex link between the community and the individual. Triple bottom line and community psychology theories were applied, and this study contributes to the social impact of CSR by focusing on both community and individual, especially in the face of natural disasters in wetlands.

The production of mocaf flour in MSME scale in South Kalimantan area was not feasible considered from its business feasibility hence the multiple effect was unmeasured based on its industry existence. Mocaf flour production derived from cassava, which is a plant that not only match on dry land but also in the wetlands of South Kalimantan, can not be oriented consumer as a substitute for wheat flour for common food products in the society. Therefore, further research refers to aspects mocaf flour premium for health. This objective of this research was to increase the society consumption of mocaf flour for the healthy reason related to the trend on negative effect from high level of gluten in wheat flour. The laboratory test showed the result that supports mocaf product for health. With this consideration then mocaf processed product have potentials to bedeveloped though serious marketing effort is required due to infamiliarity of the mocaf flour especially in South Kalimantan area. Difference test result showed that prospects, indeed, haveintention to purchase mocaf-based processed products for healthy reason.

This study aims to determine the level of students' understanding of each indicator of the buffer solution material and to determine the most difficult indicator in understanding the buffer solution material using the Four-Tier Multiple Choice diagnostic test. This type of research uses a descriptive type of research using a qualitative approach. The subjects of this study were students of class XI Madrasah Aliyyah Swasta Darul Ihsan as many as 15 students who were selected using the simple random sampling technique. The research instrument used was the Four-Tier Multiple Choice diagnostic test instrument sheet and student interview sheets. The results of this study showed that the average percentage of students who understood the concept was 32.3%, did not understand the concept was 38.1%, misconception was 20.6% and the error was 9%. Based on this research, it was found that the most difficult indicator to understand is the indicator to determine the relationship between the buffer solution and the concept of chemical equation and the indicator to calculate the pH of the acid buffer solution. So it can be concluded that the students of class XI Madrasah Aliyyah Private Darul Ihsan have difficulty in understanding the material of the buffer solution.

The quail egg business is a type of business that is now popular with the community. Good quail care is also an important thing for the community to pay attention to, including feeding that should not be late, because if it is too late to feed, the quail can no longer produce eggs. Quail is capable of producing 10 to 20 eggs in one egg. The majority of people raise about 300 to 500 quails. Automatic feeding is one of the important things in this study. The time of feeding is morning, afternoon, evening and night. Researchers also use a microcontroller, nodemcu and the Internet of Things (IOT). The function of the IOT is as a remote control media on off feeding time and control the opening and closing of the door to the quail feed.
