With the increase in population, mainly in urban sprawls, the available vegetation decreases due to land conversion into the residential area. At the same time, the rise in population is proportional to the increase in air pollution, which is characterized by the Greenhouse Gases (GHG) problems. However, naturally, vegetation can absorb greenhouse gas emissions as a component in the photosynthesis process. Increasing space for housing is balanced with spatial regulations for the use of built-up land so that some of the carbon emissions from daily activities are reduced. Based on the research, there is still a difference between carbon absorption and carbon emissions; therefore, increasing the amount of vegetation as a Green Open Space (GOS) needs to be maximized based on the number and type of plants. The air pollution problem is attempted to be done naturally so that the ecosystem will naturally reduce the existing pollutants. The Community Service (CS) stages starting from land preparation, seed preparation, pathway construction, monitoring plantation, can be a solution to answer the problems of city dwellers on a housing scale. The overall implementation of the community services has gone well, such as constructing access pathways, planting trees and flower plants, and using land for public housing facilities into parks. The environment will be safer from wild and dangerous animals to create a better environment.

Exploration of the use of medicinal plants to lower uric acid levels has been widely practiced. Stages of new drug development research is a preclinical test using experimental animals, therefore the manufacture of an animal model of hyperuricemia is necessary. This study aims to determine the optimal induction of uric acid to increase blood uric acid levels by administering high purine foods such as cow’s liver, cow’s spleen, Gnetum gnemon, emping and fried peanuts. Eighty male white rats were used individuals to be divided into 4 groups, they were: (I) cow’s liver, (II) cow’s liver and cow’s spleen, (III) cow’s liver, cow’s spleen and boiled gnetum gnemon beans, and (IV) cow’s liver, cow’s spleen, emping and fried peanuts. This study using easy touch GCU to measure blood uric acid level. The result of statistical analysis of uric acid level means with 5 times repetition using One Way ANOVA showed that there was a very significant difference between treatments (p <0,01). The results concluded that high purine diet in group I, II and III had not been able to increase uric acid levels significantly. High purine diet group IV was able to increase blood uric acid levels significantly to make the rats experiencing hyperuricemia with the level of 6.54 mg/dL on day 7 and 13.79 mg/dL on day 14.

Uric acid is an oxidation product of the xanthine oxidase enzyme found in extracellular fluid, and when it exceeds, uric acid will build up and cause hyperuricemia. TNF-α is released by epithelial cells and mesangial cells when inflammation occurs and causes apoptosis in epithelial cells, causing damage to kidney structures and initiating acute kidney poisoning. Green tea extract (Camellia sinensis L.) contains many antioxidants, especially flavonoids with potent antioxidant properties such as lipid peroxidase and free radical absorbers, inhibiting xanthine oxidase. This study expresses the potential of green tea extract on kidney repair caused by HUA. Twenty-four male albino rats (175-225 g) of Wistar strain being fed a high purine diet in 60 consecutive days and divided into six groups randomly, I: negative control, II: positive control, III: allopurinol, IV: green tea extract 150mg of body weight, V: green tea extract 300mg of body weight, and VI: green tea extract 600mg of body weight. Treatment was done for 14 days and measured by total creatinine levels, malondialdehyde levels, and kidney histopathology. The statistical analysis using One Way ANOVA and Post Hoc Tukey analysis by SPSS 23.0 proved that green tea extract with a dose of 600 mg/kg of body weight green could lower levels malondialdehyde of the kidney as much as 58.85% (p<0.01), decreased creatinine level by 24.5% (p>0.05), and improved kidney histopathology. This study proved that green tea extract is a promising alternative for hyperuricemia while improving kidney tissues and lowering malondialdehyde and creatinine levels.

Liver has an important role in detoxification of toxins such as xenobiotic which could interfere the function of liver. Chloramphenicol is an antibiotic widely used,despite of its toxicity potentials. The enhancement of free radicals in the body could suppress antioxidant activity. Propolis of Trigona sp. has been known to contain very high amount of antioxidants. The enhanced serum glutamic oxaloacetic transaminase (SGOT) and alkaline phosphatase (ALP) levels in serum is used as marker of liver damage due to the increase of free radicals. The purpose of this study was to observe the effect of Trigona sp. propolis ethanolic extract on SGOT and ALP levels in rats (Rattus novergicus) pretreated by chloramphenicol to induce liver damage. Test animals used for this research were male rats aged 8-12 weeks divided into five treatment groups: negative controlgroup (normal), positive control group (induced by 400 mg/kgBW chloramphenicol), first therapy group, second therapy group, third therapy group induced by chloramphenicol with and propolis extract with the dose of 8 mg, 16 mg, and 24 mg, respectively. Chloramphenicol was injected subcutaneously for 14 days, whereas propolis extract were administered orally for 21 days. The level of SGOT and ALP was determined using spectophotometry. The results showed that propolis extract could reduce levels of SGOT and ALP. Dose of 24 mg/kg was the effective dose to decrease levels of SGOT and ALP significantly (p<0.01). Hence, it may be concluded that the ethanol extract of propolis could be used as herbal therapy in rats model of liver damage.Keywords : ALP, liver, chloramphenicol, propolis, SGOT

Heart disease is a disease with the second-highest mortality rate in the world. This happens because of an unhealthy human lifestyle. This unhealthy lifestyle affects the performance of the body's organs in carrying out their functions. Stroke can be prevented by exercising regularly, eating nutritious foods, not consuming alcohol, and not consuming tobacco. One way to find out if someone is free from stroke or not can be done by medical check-ups. However, this method is quite expensive. Given these problems, this study aims to design an early identification system for detecting early-stage stroke. The system is designed by utilizing the condition and history of the subject for identification. This study uses a back propagation neural network for the classification process. Variations in the use of hidden layers in each experiment were used to obtain the highest accuracy in the training process. From the results of the study, it was found that the system designed can detect early stroke with an accuracy rate of 97.8%.

The provision of electricity is crucial, so efficiency must be done because electrical energy is a top priority for residential, industrial, and outdoor lights. All tiers of society must support the government's efforts to ensure the stability of the nation's energy supply through initiatives to boost supply and conserve energy. The public, particularly the lower middle class, do not yet understand the existing technology well; the information of its benefits and drawbacks have not been equally spread. Energy researchers and experts assert that the domestic or household sector's contribution to the attempt to cut power usage is very significant due to the comparatively high share of residential consumers. A project must be carried out to provide counseling in the form of instruction on cost savings when utilizing electrical and electronic gadgets in homes and schools. The counseling results revealed that the teachers of SDN 09 Pontianak Timur were genuinely interested in what they were hearing and in the presented curriculum. Through the counseling technique it is observed that the community is becoming more conscious of the need to utilize electrical energy more intelligently and is gaining new insights into how to do so. These insights help the community promoting energy efficiency in daily life.

The transformer is one of the critical pieces of equipment for distributing electrical energy from the generator connected to the transmission to the consumer of Diesel and Gas Power Generation Service Units (ULPLTD/G). Therefore, the existence of insulation is essential due to its function as a separator among the transformer core and as a transformer cooler to minimize the heat that arises in the transformer. Hence, the objective of this research was to evaluate the transformer oil quality. The procedure was executed by observing the transformer and collecting data directly from the diesel machine of SWD 2, SWD 3, and SLZ 5. The results revealed that the breakdown voltage of transformer oil categorized as good was SLZ 5 oil with an average of 59,983, and the less good was SWD 2 oil with an average of 34.516. Furthermore, by observing the test results for new and used transformer oil, the breakdown voltage value for new transformer oil was always higher than used oil. Eventually, the transformer efficiency achieved was 95.58%.
