This service activity is carried out by first explaining the importance of planting trees, greening at school, practicing planting in polybags and watering plants that have been planted. This activity was carried out at the UHO botanical garden nursery house because this activity led to direct practice of seeding plant species into polybags. The types of plants that were seeded were Bitti (Vitex cofassus), Red Jabon (Anthocephalus macrophyllus), Trembesi (Samanea Saman) and Tirotasi (Polyscias nodosa). The result of this activity is that the students look enthusiastic and excited and they can do all stages of this activity well, starting from the explanation of the importance of planting trees, the introduction of planting media such as polybags and soil, the introduction of types of plant seeds, how to plant seeds into polybags, how to water plants in polybags and hand washing activities after planting. The real benefit of this activity is that students can stimulate the sensitivity of cognitive, affective and psychomotor aspects in gaining direct experience that can strengthen their understanding of the importance of biodiversity.

Water can fulfill daily needs through human activities such as washing clothes, water for drinking, bathing, and so on. Well, water is suitable for use if it meets water quality standards. This type of research uses descriptive research methods. This research is located in Baruga Market, Anduonohu Market, Lorong Salangga, and Kendari Permai Kendari City in December 2023. the samples used in this study amounted to 4 wells. The results obtained in this study are that all well water is polluted with E. coli, and Baruga Market well water exceeds the quality standards for Coliform parameters. The presence of E. coli in all well water samples indicates fecal contamination, posing severe health risks such as waterborne diseases. Baruga Market's well water exceeds Coliform standards, likely due to sewage runoff, making it unsafe without treatment. Immediate actions, like improving sanitation and providing clean water alternatives, are necessary to prevent further contamination and protect public health.

Green Open Space (RTH) is essential in supporting ecological balance and improving the quality of the urban environment. Although Law No. 26 of 2007 mandates the allocation of 30% of land for RTH, only about 10% is managed privately and 20% by the public sector. This study aims to evaluate the green space quality of Kendari Botanical Garden, the first conservation space in Southeast Sulawesi, covering an area of 113 hectares, which is a crucial conservation center in Southeast Sulawesi in preserving biodiversity, especially endangered endemic plants. Apart from being a place for research and environmental education, the botanical garden also supports ecotourism, ecosystem restoration, and the provision of seed sources to maintain germplasm sustainability. However, Kendari Botanical Garden experiences accessibility and infrastructure challenges despite physical development. The methods used include interviews, observations, and literature studies, with descriptive analysis of aspects of accessibility, activities, and facilities. The results showed that the accessibility aspect received a good rating, while the activity and facility aspects were fair to good. This research emphasizes the need for improvements to meet the needs of sustainable urban planning and improve visitor comfort so that Kendari Botanical Garden can function optimally as an inclusive and user-friendly RTH; these improvements can be in the form of road infrastructure improvements, additional recreational facilities, and educational programs.

The samples were collected using stratified random sampling methods with a Surber sampler 30 cm x 30 cm, 5 segmented streams, and 200 m with 4 replication. The results show that 19 species of 5 community feeding groups were found, including collector filters, gatherers, predators, scrapers, and shredders. However, the shredders community is very small, at about 2-4 %. The benthic insect aquatic dominance by collector filter with 29 % reflected that input from terrestrial vegetation is Fine Particulate Organic Matter (FPOM). Therefore, it can be deduced that Sampolawa headwaters do not fit with the prediction of the "River Continuum Concept (RCC)"for a typical headwater since the allochthonous energy supply from riparian vegetation is in the form of fine detritus.

Considering that clean water is an unlimited and sustainable need that must be fulfilled every day, it is not only about a sufficient amount of discharge but in quality, it meets a proper standard and in quantity and continuity must be able to meet the needs of the population it serves. In the aspect of economic life, water is also important for agriculture, cultivation, power generation, transportation, and industry. The entire population of Indonesia has the right to obtain adequate, adequate, and affordable clean water infrastructure and facilities. The purpose of this research is to analyze the projections and mapping of the need for clean water sources for the population and the need for facilities and infrastructure to increase the availability of water sources. The research location covers the entire administrative area of Muna Regency which consists of 22 districts that oversee 152 villages/wards, namely Kontunaga, Watopute, Katobu, Lohia, Duruka, Batalaiworu, Napabalano, Lasalepa, and Towea districts (Zone I). Furthermore, the districts of Tongkuno, Tongkuno Selatan, Parigi, Bone, Marobo, Kabawo, Kabangka, and Kontu Kowuna (Zone II). And in the districts of Wakorumba Selatan, Pasir Putih, Pasi Kolaga, Maligano, and Batukara (Zone III). The data obtained are in the form of population data, population projections, projected domestic water needs for the population, projected non-domestic water needs for the population, projected total water needs for the population, and projected drinking water supply system needs which are then analyzed from 2015-2035 in quantitatively descriptive. The results showed that the results of the calculation of the projected water needs of the population according to the Water Source zone of Muna Regency in 2015-2035 showed that the water demand of Muna Regency in 2015 was 8,606 m 3. The water demand for the next five years, namely in 2020 for the entire zone, is 9.600 million m 3. It was further explained that the total water demand for the entire water source zone of Muna Regency in 2025 was 10,709 million m 3. The total water demand for the Prime Archives in Sustainability: 3 rd Edition 3 www.videleaf.com entire water source zone of Muna Regency for the next five years, namely in 2030 is 11.946 million m 3. Furthermore, it is explained that the total water demand in the study area in 2035 is 13,326 million m 3. As for the number of drinking water supply systems in Muna Regency, there are 27 units in Zone I as many as 13 units, Zone as many as 10 units, and Zone III as many as 4 units. The need for drinking water supply systems in Zone I is 19 units, Zone II is 12 units and Zone III is 5 units.

The samples were collected using stratified random sampling methods with a Surber sampler 30 cm x 30 cm, 5 segmented streams, and 200 m with 4 replication. The results show that 19 species of 5 community feeding groups were found, including collector filters, gatherers, predators, scrapers, and shredders. However, the shredders community is very small, at about 2-4 %. The benthic insect aquatic dominance by collector filter with 29 % reflected that input from terrestrial vegetation is Fine Particulate Organic Matter (FPOM). Therefore, it can be deduced that Sampolawa headwaters do not fit with the prediction of the "River Continuum Concept (RCC)"for a typical headwater since the allochthonous energy supply from riparian vegetation is in the form of fine detritus.

We assumed the forest fires caused the reducing of organic allochtnous input to the streams and changed the functional group of benthic insects of the headwaters. This research was study the abundance of the functional group of bentic insects in responding to the allochtonous input the streams post forest-fire due to the pyroclastic flows and eruption. Samples were collected using Surber Sampler of (30x30) cm2 at 5 cm sediment depth along 200m of the stream, which was divided into 5 segments of 20m of straight stream. At each segmnt, smaples were collected with 4 replicates. Results reveal that collector gathers Chironomous sp 99% dominated both streams. The sediment nutrients of NH4NO3, and PO4 were high. Shredder,Prionocera sp. was found only at Kali Boyong, and collector filter, Hydropsyche sp. was present only at Kali Kuning. Thus the forest fire of post pyr...
