Talking about the sustainability of life, humans cannot be separated from their dependence on energy needs. Most of the energy sources that we have used so far are fossil energy sources that are non-renewable. With the high dependence of humans on energy, innovation is needed to minimize energy limitations. One form of new renewable energy that can overcome this is Biogas. Biogas is a gas that can be obtained from the fermentation of livestock waste through technology in the form of an airtight tube called a biodigester which is useful in processing livestock waste into biogas energy. Through research that the group conducted using the literature review method, we found one village in Riau that has succeeded in utilizing biodigester technology to make biogas, namely Mukti Sari Village, Tapung District, Kampar Regency, which has now succeeded in becoming an energy independent village.

This study uses a qualitative method to describe the infestation of Oryctes rhinoceros beetles in oil palm plantations and its impact on crop productivity. This pest poses a major threat to oil palm cultivation due to its ability to damage the growing points of both young and mature plants, resulting in a significant decline in yield. The study was conducted through field observations and in-depth interviews with farmers and field technicians at an oil palm plantation in Sumatra. The findings reveal that Oryctes infestations are more prevalent in plantations with poor sanitation and limited implementation of regular biological control systems. Farmers predominantly rely on mechanical and chemical control methods, which have proven to be less effective due to the lack of coordinated and sustainable application. Therefore, an ecologically-based integrated pest management strategy is needed, combining biological control, cultural practices, and farmer education to effectively suppress pest populations and ensure the sustainability of oil palm production.

Education plays an important role in shaping the character and intelligence of the younger generation, with discipline as a key value that must be instilled from an early age, especially in elementary schools. Discipline not only maintains order during the teaching and learning process but also shapes students' personalities comprehensively. This study uses a descriptive qualitative approach through observation, interviews, and documentation to understand student discipline practices and the role of teachers in instilling this value in the classroom. The results show that discipline significantly contributes to students' academic success and is developed through consistent habituation. The teacher’s role as a behavioral model is crucial in fostering discipline awareness, with strategies involving students in rule-making as well as the implementation of educational rewards and punishments. Conversely, a lack of discipline causes disruptions in the learning process and lowers academic achievement. Therefore, sustainable discipline development involving multiple stakeholders is necessary to create an effective learning environment and strong student character

Poverty is a multidimensional problem that is not only related to economic aspects, but also social, cultural, and political, which affects the welfare of poor families. The Family Hope Program (PKH) in Makassar City is designed as a conditional social assistance program that aims to improve the welfare of poor families through the provision of financial assistance and increased access to basic services. This study aims to explore the role of social companions in building trust, factors that affect the participation of poor families, and obstacles in the implementation of PKH. The method used was descriptive qualitative with subjects of 10 beneficiary families and 3 social companions, data was collected through semi-structured interviews and participatory observations, then analyzed thematically using an inductive approach. The results of the study show that social companions play a crucial role as communication mediators who build trust through an empathetic and familial approach, which strengthens the sense of belonging to the program. Family participation is influenced by social capital, local cultural norms, education levels, as well as bureaucratic constraints and access to services. Barriers such as social stigma, complicated bureaucracy, and limited companion training hinder the effectiveness of the program. Habermas's theory of communicative action and Durkheim's social solidarity support the finding that open dialogue and harmonious relationships between companions and families are key to successful social empowerment. It was concluded that strengthening the capacity of companions, simplifying bureaucracy, and increasing participatory dialogue spaces are needed to increase the effectiveness and sustainability of PKH in Makassar.

The problem that often arises now is the increase in living costs while income remains constant. With empty land in the household that is not being utilized optimally, this should be an opportunity for housewives to help improve the household economy. One solution to utilize this empty land is through hydroponic plants. This hydroponic plant uses organic fertilizer so that the hydroponic plant is good for family consumption and distribution in supermarkets. By utilizing hydroponic plants, housewives can help improve the family's economy so that the family's needs can be fully met. In this research, the researcher conducted an interview with one of the housewives who had used her yard through hydroponic plants that she had developed herself since 2017. The aim of the research was to determine the economic improvement experienced by housewives after using the hydroponic system.

The legal protection of well-known trademarks in Indonesia still faces various challenges, especially in overcoming passing off actions that can harm trademark owners and mislead consumers. The doctrine of likelihood of confusion becomes the main instrument in determining the extent to which the similarity of a brand can cause confusion among consumers. This research aims to analyze the implementation of legal protection of well-known trademarks from the act of passing off in Indonesia, focusing on the Golden Goose case. The research method used is doctrinal legal research with a statute approach and case approach. The data used is secondary data obtained through a literature study of legal regulations, court decisions, and relevant academic literature. The results show that although Indonesia has adopted the doctrine of likelihood of confusion in the Trademark Law, its application still faces various obstacles. The first to file system adopted in trademark registration opens up opportunities for parties with bad intentions to register trademarks that resemble well-known trademarks. This can be seen in the Golden Goose case, where another party registered a similar mark before the legal owner registered in Indonesia, triggering a legal dispute. The court eventually canceled the mark based on significant similarity and potential consumer confusion. This study confirms that it is necessary to strengthen the legal protection mechanism of famous marks, including increased supervision in trademark registration as well as strengthening regulations to prevent passing off.
