Sanrobone is a coastal village with tourism potential, including cultural heritage sites and mangrove forests. However, most of the forests have been converted into fish ponds and seaweeds, resulting in abrasion that erodes the village and damages several historical sites in the area. The program aims to empower millennial generation in preserving the cultural reserves and mangrove forests, which in turn can become a community income sector. The millennial generation of Sanrobone is participating in repairing the Sanrobone Fort (Benteng), the Sanrobone King’s Graves, and the mangrove forests through the development of cultural and mangrove-based tourism. This outreach activity employed an active participatory method, namely: (1) Socialisation of the Culture and Mangrove Tourism concept to the community and local government; (2) Training in mangrove planting and management; (3) a comparative study trip to developed cultural tourism and mangrove-based tourism areas. The results showed the millennial awareness of the tourism potential of the region is getting higher, and they can already see various opportunities to manage these tourism potentials as a source of income. What needs to be done next is to improve the skills of the millennial generation in the promotion of regional tourism through digital marketing, which is needed for effective sustainable tourism development in the industrial era 4.0.

Makassar is one of the cities with the largest population in Indonesia so that the volume of waste that goes to the landfill is quite large. The most common type of waste is organic waste, which generally comes from households. Therefore, the target of this activity is women in the household as the controller of domestic affairs. The purpose of this activity is to know the transformation of the role of women in reducing and handling their household waste. The method used is qualitative descriptive method conducted through interview, observation and document study. The activities were carried out in the form of: (1) Household waste management socialization, (2) Training on reducing and handling household waste, (3) Practice of making composter and Biopore Infiltration Holes (LBR), (4) Assistance in the use of compost and processing of anorganic waste into useful items in the household. The results of the activity show that transformation of knowledge and the role of household women regarding household waste management, as well as increasing creativity and innovation of household women in processing waste so that it has economic value.

Tilapia is one type of freshwater fish that has economic value. This type of fish has good adaptability and fast growth. One of the problems in tilapia cultivation is that probiotics have not been utilized in the maintenance media with a biofloc system. This study aimed to determine the dose of probiotic supplementation in the formation of bioflocs on the growth and survival of tilapia. The research was conducted at the Educational Pond, Bosowa University, Maros Regency. The test animals used were tilapia seeds measuring 2-3 cm long. The stocking density of 3 seeds/L were kept in a basin with a capacity of 80 L filled with 60 L of water. The treatment tested was GDM probiotic supplementation in media with doses of A 5%, B 6%, C 7%, and D 0 %. The study used a completely randomized design with 4 treatments and 3 replications so that there were 12 experimental units. Seeds were reared for 60 days by feeding Hi-Pro-Vite FF-99 as much as 3% of body weight biomass per day. The results showed that GDM probiotic supplementation with different doses significantly affected the growth and survival of tilapia. Supplementation of GDM probiotics 5%, 6% and 7% in the media gave the same effect on the growth and survival of tilapia but significantly different from the treatment without probiotics. The highest growth and survival rate of tilapia was obtained at a dose of 5%, 4.27g and 65%, respectively, while the lowest was in the treatment without probiotics, namely 3.27g and 48.33%. Based on the results of the study, it is recommended that 5% GDM probiotic supplementation in tilapia rearing containers is recommended.
