Riparian forest is a source energy and matter for the aquatic ecosystem. The abilities of riparian forest are to control and recycle the allochthonous inputs from the upland drainage basin and the river itself. This processess are a fundamental aspect of river ecology. We studied the riparian forest in karst ecosystem setting, at the protected forest of Sampolawa headwaters river, Baubau, Southeast Sulawesi. We focussed on the structure and composition of species richness of the forest. Data were collected using quadrate methods, 20mx20m, with 4 replicates placed at each river side. Results reveal that the forest compossed of 7 growth-forms, trees, saplings, seedlings, palm, herbs, liana, and spike moss. The tree species richness of tree and sapling was 33 and 37 species in consecutively. The tree species of Sphatolobus sp., Aglaia silvestris, and Canarium asperum dominated this riparian forest. Similarly the sapling dominance were Sphatolobus sp., Aglaia sp., and Chrysophyllum lanceolatum, as well as the seedlings of Sphatolobus sp., Palaquium obovatum and Chrysophyllum lanceolatum. Thus, the Sphatolobus sp. will be the future tree. However, Anthocephalus macrophyllus saplings were not found, thus this tree was endangered. Soil nutrients of NO 3 , NH 4 , PO 4 , and C organic were high, which indicated that the litterfall decomposition occurred at the forest riparian floor. The Riparian forest was a primary forest and very diversed in species richnes but had low densities. All the tree, sapling, and seedling species characterized the riparian forest of karst ecosystem at the headwaters of Sampolawa River in the karst ecosystem setting.
The workshop business will produce waste that is not managed properly, it will have an impact on the environment and humans. Knowledge and attitude of workshop mechanics can influence the behaviour of workshop mechanics in managing B3 waste generated from motorcycle repair businesses. This study aims to determine the level of knowledge of mechanics, mechanical attitudes, and patterns of reducing waste in two-wheeled motor vehicle workshops in Kendari City. The method used in this research is a survey method through interviews using a questionnaire. Data analysis is by using the Gutman scale and then the results will be analysed using quantitative descriptive analysis. The results showed that the mechanics of the workshops located in Kendari City in 11 sub-districts mostly had knowledge that was in the doubtful category. Mandonga sub-districts 62%, Kambu sub-districts 61.66%, West Kendari sub-districts 38.66%, Poasia sub-districts 46.33%. Wua-Wua sub-districts 33%, and Puuwatu sub-districts 56.66%. The attitude of mechanics tends to be willing to manage B3 workshop waste, which is found in 8 sub-districts which include Abeli sub-districts 77.97%, Mandonga sub-districts 51.06%, Kambu sub-districts 63.63%, Baruga sub-districts 54.73%, Kendari sub-districts 76.47%, Puuwatu and Kadia sub-districts 57.14%, and Nambo sub-districts 70.27%. There are only 3 sub-districts that carry out the management process for B3 waste, namely Kambu sub-districts 66.66%, Kendari Barat sub-districts 58.81%, and Puuwatu sub-districts 75%.
The Nipa-Nipa Grand Forest Park is a conservation forest area in Southeast Sulawesi. This park has potency of hydrological function and serves as the lungs of Kendari City. Its existence is currently used by residents for agriculture, clean water sources, settlements, and tourism without proper regulation and supervision. Therefore, it has potentially caused monopoly, unilateral control, and conflicts. In line with that, the lack of awareness and initiative from the community and stakeholders in maintaining the sustainability of the Nipa-Nipa Forest triggers uncontrollable damage. This study aims to restore hydrological function and conservation of the Nipa-Nipa by redefining role of stakeholders involved in its governance by using the Participatory Action Research (PAR). This method’s actions consist of participatory mapping, planning, and agreements. The outputs of this approach were an increase of community participation in Nipa-Nipa management, the improved capacity building of Forest Conservation Farmers Groups (KTPH), the enactment of new regulations of the implementation of the Nipa-Nipa Forest Park, and the ratification of the MoU between the Farmers Group (KTPH) and the Nipa-Nipa Forest Management Unit (UPTD). The results of this study were developing a strategy for a better governance system, involving stakeholders in decision making, developing equal and harmonious government-community relations, and developing land-use planning that meets environmental conservation, and small sustainable business development.
The social media phenomenon increasingly widespread and uses as a references news, information and knowledge. The development of social media also gave birth to many phenomena including the emergence of a phenomenon called buzzer. Twitter as an identical media uses buzzer activities because it has a grand gait on enlivening dialogue and as trendingtopic, a news categorize according to key terms or exclusive topics through fence syndication (#) to move social media users.This research related to the tendency of content exchanged buzzer and followers. The research results are presented in the form of descriptive qualitative research, which aims to describe the character of the message contained in the information exchanged by the buzzer. The samples used in this study were 15 tweets about #ILCPanggungProvokasi and 13 tweets about #StopAcaraILC.This study does not prioritize the size or sampling. If the data collected is in-depth and can explain the phenomenon being studied, there is no need to look for other sampling. The emphasis here is on the problem of depth (quality) of data, not quantity of data. The research period focuses on buzzer content in the period from February 18 to February 20, 2020, which is a trending topic and is discussed openly by the public, giving rise to a certain understanding that is widespread. The Result of this reaserch show that The interaction of buzzer information on Twitter social media is a deliberate relationship because of the formation of manipulated content in political discourse through the hashtag #ILCPanggungProvokasi as an early advocate of discourse. The buzzer then creates a counter-discourse via #StopAcaraILC, which is offensive in nature with agitative and monotonous discourse.transactions on Twitter social media as an activity are not of high quality but are able to attract attention and are widely responded to by the public.
Clean water is a basic need of the community to live properly following the targets of development policies to realize the Cipta Karya program 100 -0 -100, namely 100% access to clean water, 0% slum settlements, and 100% access to good sanitation. 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 www.videleaf.com entire water source zone of Muna Regency for the next five years, namely in 2030 is 11.946 million m 3 .
