Housing procurement for low to middle-income people in Palembang is carried out by the government and developers with the direction of housing development towards the outskirts of the city. One of the directions of development is the Talang Kepuh area, Ilir Barat 1 district. Housing development in this area is carried out in a wetland area where some of the condition of the area is swampland so that in its construction it must have its characteristics because the land has been piled up. In addition, the problem of housing development is the difficulty of the need for clean water. Simple housing design that is environmentally sound with rainwater harvesting system as an alternative solution to problems in water supply, so that it can meet the residential needs of the community. The results of the analysis discussion are outlined in the form of a simple concept of planning and designing a simple house with an environmental perspective. Rainwater harvesting is an important use to reduce excess surface runoff that causes flooding, land subsidence, and dryness of groundwater reserves. Where rainwater from the roof of the house will be dispensed into the distribution pipes which will then be forwarded and accommodated in water tanks. Meanwhile, if the excess water is accommodated, it will be dispensed to the retention pond. The calculation is done by calculating the discharge from the rainwater covering the roof of the house, then the volume of the water tank will be obtained to get the dimensions. After getting the dimensions of the water bath will be calculated the necessary costs. The costs calculated are excavation and backfill of soil, concrete materials, pipelines, and workers' wages. So that a water reservoir can be made with concrete material that will be used for water needs. The stored water will be used as raw water. For use as cooking or drinking water, further research is needed.

Infection is a disease that is easily found in tropical areas such as Indonesia. The causes of infection that are easily found include infections due to fungi. One of the fungi that causes many infections is the Candida fungus. Tropical drugs commonly used to treat cutaneous candidiasis include nystatin, clotrimazole, miconazole, ketoconazole and other azoles. However, antifungal drugs have limitations, such as severe side effects, poor penetration into certain tissues, and the emergence of resistance. To overcome the negative effects caused by these synthetic antifungal drugs, it is necessary to explore natural antifungal drugs. One of the plants that has the potential as a medicinal plant is the mango parasite plant (Dendrophthoe pentandra (L.) Miq) which is a parasitic plant that attaches to the host which has the potential as herbal medicine. Research on the potential of active compounds in the leaves of mango parasite (Dendrophthoe pentandra (L). Miq) as antifungals has been carried out from November 2020 to June 2021 at the Genetics and Biotechnology Laboratory, Biology Department, FMIPA Sriwijaya University. The purpose of this study was to obtain fractions that had antifungal activity, to obtain isolates that had antifungal activity, what active compounds were present in the leaves of the mango parasite as antifungal, and to determine the minimum inhibitory concentration of the fungus Candida albicans. Based on research that has been carried out with methanol, n-hexane and ethyl acetate extracts that are active as antifungals, namely n-hexane and ethyl acetate extracts with an n-hexane inhibition zone diameter of 12 mm while ethyl acetate is 10 mm. Then purification of the n-hexane and ethyl acetate fractions was carried out using gravity column chromatography and the n-hexane fraction obtained two pure compounds that were active as antifungals, namely isolate N-1 with a diameter of 12 mm and N-4 with a diameter of 10 mm. Two pure acetate fractions were obtained which were active as antifungals, namely isolates E-1 with a diameter of 10 mm and E 5 with a diameter of 12 mm. Furthermore, the results of the eluate were tested by MIC and thin layer chromatography (TLC). The MIC results on isolates N-1, N-4, and E-1 were able to inhibit at a concentration of 500 ppm and were classified as strong. Meanwhile, isolate E-5 was able to inhibit at a concentration of 1000 ppm which was classified as moderate. The TLC results showed color spots on isolate N-1 which were blue, namely terpenoids, while in isolate N-4 which was orange in color were alkaloids, while in isolate E-1, the color was phenolic yellow, while in isolate E-5, which was purple, it was group terpenoids. The results of the bioautography of isolate N-1 with R¦ value: 0.9, isolate N-4 with R¦: 0.6, isolate E-1 with R¦ value: 0.8, and isolate E-5 with R¦ value: 0,9.

Planting glutinous corn on peatland must be treated using ameliorant ingredients of manure fermented with EM4 and growth regulators. Ameliorated peatland can accelerate the supply of organic and mineral compounds which is easily absorbed by plants so that production can be optimized. This study aims to see the response of ameliorant ingredients and growth regulators on the growth and production of glutinous corn of Arumba (Zea mays L. Ceratina) variety on peatland. This study used a randomized block design (RAK) in factorial consisting of two factors, and three replications. The first factor was the ameliorant material (A), namely A0 = without ameliorant (control), A1 = cow manure fermented with EM4, A2 = chicken manure fermented with EM4, A3 = goat manure fermented with EM4 and he second factor is the type of Growth Regulatory Substance (ZPT), namely Z0 = without ZPT (control), Z1 = Superior Plant Hormone Growth Regulator (Ghost), Z2 = Harmonic Growth Regulatory Substance, Z3 = Atonic Growth Regulator Substance. The variables observed included plant height (cm), stem diameter (cm), weight of wet bean (g), weight of ear (g), length of ear (cm) diameter of ear (cm). The results showed that the ameliorant material from chicken manure fermented with EM4 and the use of superior plant hormone growth regulators (phantoms) provide optimal growth and production of glutinous corn because it corresponds to the description of glutinous corn of the Arumba variety, and is the best treatment.

The landfill environment in Palembang City produces various types of waste so that people keep free-range chickens around the environment, which is potentially harmful to livestock health. This study aims to determine the color morphology of the internal organs (liver and heart) and the relationship between body weight and organ weight. The number of free-range chickens used was 30, with one year. The morphological description of organ color was carried out by direct observation, and sampling was carried out by weighing free-range chickens body weight and organ weight. This study used the Pearson correlation statistical test, and secondary data was collected on waste data in the landfill environment. The results showed that the relationship between body weight and liver weight was 0.694, and the correlation value between body weight and heart weight was 0.663 in native chickens in the landfill environment. The results of the two values have a strong correlation interpretation, which means that when the chicken's body weight increases, the weight of the liver and heart of the chicken will also increase. The liver is faded red with normal size in native chickens in the landfill environment in the morphological picture. While the color of the heart is red, and the size is normal.
