Psychosocial Health: Hidden Effects in the Water Supply and Sanitation Environment
Full text linkThe conceptualization of water and sanitation as the foundation of life is the key to the success of sustainable development in the health sector. Fulfilling water and sanitation needs often encounters obstacles in the environment of certain family groups that touches the complexity of psychosocial health problems. The facts show that attention is often neglected to the impact of inadequate fulfillment of clean water and sanitation on psychosocial health. It is very important to further explore the impact of water availability and sanitation on psychosocial health in order to achieve sustainable health development. This qualitative research was carried out with a phenomenological study approach, involving 5 families living on the riverbank in Palembang, South Sumatera Province. The in-depth interview method is carried out until it reaches data saturation, observation and field notes are carried out during the data collection process. The results of data collection were analyzed using the Colaizzi method to obtain four themes including: stress due to not getting access to clean water, economic difficulties that cause emotional distress in accessing clean water, compulsion to use available water and inconvenience to use public sanitation facilities. The implication of this research is the need for policies to facilitate certain groups of people to access their needs for clean water and sanitation by paying attention to the psychological aspects of the community. Collaboration of community leaders is needed in accelerating access to clean water and sanitation that is more respectful of community dignity
Rice Demfarm Financing Model in Trial Of Excelent Variety on New Operating Land Cooperation Between Stakeholders and Partners
Full text linkRice productivity can be increased by expanding the number of inputs or through the application of new technologies. Demonstration Farm (Demfarm) is one of the methods used for the adoption of agricultural technology according to the developed potential commodities. This study intended to determine the financing model for lowland rice located in Sungai Dua Village, Rambutan District, Banyuasin Regency based on the variety used in relation to rice field construction. The method used was a trial or experiment. This research was conducted on an outdoor laboratory area of the University of South Sumatra in collaboration with partners (IPB University, PT ATS Inti Sampoerna, PT PUSRI, BPTP). There are 3 superior varieties used consisting of IPB3S, Inpari 32 and Ciherang covering an area of 6 hectares in 2021. The population of this study are all farmers who participate in the new rice field printing program that will be formed into the Rice Estate Community (KEP), as many as 15 people who own land and farm laborers by using the census method considered that the entire population as the sample. The analysis used is qualitative and quantitative analysis. The results showed that the income earned by the University of South Sumatera in the first period was Rp.(7,3977,235)/0.5 Ha/MT for the IPB3S variety, Rp.(6,638,485)/0.5 Ha/MT for the IPB3S variety. Inpari 32 and p(5,949,235) /0,5 Ha/MT for Ciherang variety. Constraints faced were soil pH <4, pH of water between 2-3 and still contains pyrite, shallow swamp land type endanger to flooding, inappropriate irrigation and land conditions that still had a lot of tree trunks left. The feasibility analyses used were the B/C ratio and R/C ratio, the results of which showed that based on superior varieties the B/C ratio for the IPB3S variety was (0.80), the Inpari 32 variety was (0.79 ) and Ciherang variety was (0.74). While the R/C ratio in the IPB3S variety was 0.20, the Inpari 32 variety was 0.21 and the Ciherang variety was 0.24. The B/C ratio and the R/C ratio value < 1 indicated that the activities of this model of financing of new rice farming for the first planting period were not feasible due to natural hazard, technical and inappropriate facilities. This research showed that the better resistance and adaptation were shown by the Ciherang variety
