Community service is an important activity in increasing community capacity and welfare. In an effort to support sustainable agriculture, training on making liquid organic fertilizer (POC) with high nitrogen content aims to provide knowledge and skills to the community to use organic waste as a basic ingredient for fertilizer. Liquid organic fertilizer which has a high nitrogen content plays an important role in increasing soil fertility and plant productivity without damaging the environment. This training includes an introduction to organic materials that are easily available and available nearby, fermentation techniques, as well as methods for making appropriate POC to produce fertilizer with high nitrogen levels. This training also explained the ecological and economic benefits of using liquid organic fertilizer compared to synthetic chemical fertilizer. Training participants are taught from basic theory to practical application, so they can apply this knowledge to plants. With this training, it is hoped that the community can increase agricultural productivity, reduce dependence on chemical fertilizers, and create a friendlier and more sustainable environment.

This research aims to examine the state's responsibility in protecting Indonesian migrant workers in an effort to fulfill human rights. Indonesian migrant workers have an important role in the nation's economic development. As a contributor to the country's foreign exchange, legal protection for Indonesian migrant workers abroad is very important. The placement of migrant workers abroad has increased. The increasing interest of Indonesian migrant workers abroad is in line with the growing complexity of problems faced by Indonesian migrant workers in the form of human rights violations, verbal, physical, and sexual harassment, and other violence. The urgency of this research is to determine the role and responsibility of the state in protecting Indonesian migrant workers, especially those abroad, based on existing laws and regulations, such as the existence of Law Number 18 of 2017. This research is normative legal research. Updates and research results carried out by the government regarding the protection of Indonesian migrant workers have been regulated in Law Number 18 of 2017. Forms of protection are carried out starting before placement, during placement, and after placement. From the research conducted, it was concluded that the state's responsibility and protection for Indonesian migrant workers still need to be improved.

Butuh Village is one of the villages in Butuh District,  Purworejo Regency, Central Jawa Province. The villages’s need for awareness of adequate sanitation is still quite low. This can be proven by the fact that there are still many houses that do not have adequate domestik waste processing infrastructure. AS we know, if we dispose of domestik waste in the form of grey water and black water directly into the environment without a good waste processing system, it will pollute the environmen. The aim of this design is to determine the domestik wastewater treatment bulding in Butuh village using the hierarchical method.The final calculation using the hierarchical method resulted in thr selected domestic wastewater treatment being the Anaerbic Buffled Reactor (ABR) using 4 parameters in the form of maintenance operatinal cost, land area used, construction costs and removal efficiency. The Anaerobic Buffled Reactor (ABR) is planned to have 5 compartments with a BOD removal efficiency of 84%, construction cost of Rp. 67.899.607, the land area required is 45 m2, and operational costs are Rp. 2.605.281 and maintenance is relatively easy.
 
 

Early marriage is a significant social problem in Indonesia, including in Cilengkrang District, Bandung Regency. In an effort to address this problem, the Indonesian government issued Law Number 16 of 2019 which sets the minimum age of marriage to 19 years for both men and women. Community service in socializing this law in Cilengkrang Sub-district aims to increase community understanding and compliance with the regulation. The program involves various educational activities, such as counseling, group discussions, and training for community leaders and educators. The methods used include direct approaches through village meetings and indirect methods through social and print media. The results showed that the involvement of community leaders and religious leaders was very effective in conveying messages and reducing resistance to legal change. The main challenges faced were changing entrenched mindsets and problems accessing information in remote areas. Recommendations to improve the effectiveness of this program include increasing the involvement of community leaders, optimizing the use of media, continuous training, inter-agency cooperation, periodic evaluation, and a culturally sensitive approach. With the implementation of these recommendations, it is expected that the socialization of the marriage age limit law in Cilengkrang Sub-district can be more effective, reduce the number of early marriages, and create an environment that supports the optimal development of children and improves the overall welfare of the community.

The construction of a high-rise building is a construction project that can be said to have high risk factors so that it will have a negative effect on the project schedule, quality, and costs needed. Project risk management analysis is needed to control risks and to determine risk handling to prevent the occurrence of dominant risks in construction projects. In this study, primary data collection was carried out by distributing questionnaires, while secondary data was obtained through data from projects and literature studies. The data obtained from the questionnaire will be analyzed for risk variables using the Severity Index (SI) method. Meanwhile, the risk level analysis uses the Probability Impact Matrix (PIM). The results of the analysis show that there is a dominant risk that has the most influence on the time aspect is the risk of delay in material delivery with a high level of risk. The dominant risk that has the most influence on the cost aspect is the occurrence of equipment damage while working with a medium risk level. The dominant risk that has the most influence on the quality aspect is that the quality of the material is not in accordance with the quality specifications with a medium risk level.

Household sewage treatment in Surakarta City depends on the performance of the available domestic wastewater treatment plants (IPAL), including Pucangsawit IPAL, Semanggi IPAL, Mojosongo IPAL, and UNS IPAL. Each of these IPAL’s serves a specific area, such as the UNS IPAL which serves the UNS area and its surroundings, the Mojosongo IPAL which is in charge of the North Area of Surakarta, the Semanggi IPAL which takes care of the South Area of Surakarta, and the Pucangsawit IPAL which serves the Central Area of Surakarta City.

This study aims to analyze the impact of administering commercial probiotic bacteria on the wastewater from tofu industries on changes in Bio-logical Oxygen Demand (BOD) and Dissolved Oxygen (DO) levels. Tofu industry wastewater is known to have high BOD and low DO levels, which pose a potential environmental pollution risk. This study used a pure experimental method with variables including the ratio of tofu industry wastewater to commercial probiotics (1:1, 1:2, 1:3) with an incubation interval of 8 hours. The results showed that the administration of commercial probiotic bacteria significantly reduced BOD levels and increased DO levels in the wastewater. The 1:3 ratio of tofu industry wastewater to commercial probiotics showed the most optimal effect in increasing DO and decreasing BOD. An incubation time of 32 hours showed the most optimal effect in increasing DO and decreasing BOD. The 1:3 volume ratio between tofu wastewater and probiotics (25% tofu wastewater and 75% probiotics) proved to be the most effective, with the highest DO increase of 2.51 mg/L and the largest BOD decrease of 144.20 mg/L. In addition, incubation time also had a significant effect, the longer the incubation time, the more optimal the probiotic activity in reducing BOD levels and increasing DO levels. The conclusion of this study is that the administration of commercial probiotic bacteria at a 1:3 ratio and an incubation time of 32 hours is an effective way to improve the quality of tofu industry wastewater.
