Regeneration Gas Heater (RGH) merupakan komponen penting dalam proses regenerasi katalis sebelum gas memasuki unit kriogenik. Efisiensi termal RGH dipengaruhi oleh rasio udara-bahan bakar (AFR), yang menentukan kualitas pembakaran dan besarnya kehilangan energi. Penelitian ini bertujuan menganalisis pengaruh AFR terhadap efisiensi termal RGH berbahan bakar metana. Percobaan dilakukan pada heater kapasitas 1001 kW dengan variasi AFR dari 16,1 hingga 17,5 (interval 0,1), di mana dilakukan pengukuran temperatur masuk dan keluar gas, konsumsi bahan bakar, serta analisis termodinamika dan emisi. Hasil menunjukkan efisiensi maksimum sebesar 83,99% terjadi pada AFR 17,2:1. Analisis regresi kuadratik menunjukkan koefisien determinasi (R²) sebesar 0,906 dengan nilai p < 0,01, menandakan hubungan yang signifikan antara AFR dan efisiensi. Optimasi AFR tidak hanya meningkatkan efisiensi energi, tetapi juga menurunkan emisi CO dan NOx secara signifikan.

Nausea and moting affect most women in early pregnancy. Up to 80% of women experience nausea and vomiting to some degree during the first trimester, and for some, these symptoms typically resolve by 12 to 14 weeks. Nausea and vomiting can occur due to elevated levels of estrogen and HCG (human chorionic gonadotropin),but psychological factors also play a role in this condition. Complaints of nausea and vomiting are physiological in nature; however, if not promptly addressed, they can turn pathological and lead to pregnancy complications. Non-pharmacological methods, such as lemon-infused water, can effectively tackle nausea and vomiting. This quantitative research determined the effect of lemon-infused water on relieving nausea and vomiting in pregnant women during the first trimester with a pre-experimental design and a one-group pretest-posttest design. The population of this study consists of pregnant women in their first trimester suffering from nausea and vomiting at the Kedungmundu Public Health Center. The chosen sampling technique was purposive sampling yielded a sample size of 30 pregnant women in their first trimester. The Wilcoxon statistical test and the result show a p-value of 0.000 (p<0.05), accepting the alternative hypothesis (Ha) and rejecting the null hypothesis (Ho). This indicates that giving pregnancy women lemon-infused water relieves nausea and vomiting during the first trimester.

The Tanjungpura University Hospital building is located in the city of Pontianak, which is situated on the equator and often faces the potential of lightning strikes, thus requiring the installation of an external lightning surge protection system. This study aims to design an external lightning surge protection system capable of protecting the Tanjungpura University Hospital building using the rolling sphere method. In the rolling sphere method, calculations will be made for the lightning strike distance (R), protection radius (Rp), protection area (Ax), and determination of protection angle (?). The University Tanjungpura Hospital building is at protection level IV, with a current strength of I = 16 kA and a lightning strike distance to the ground of 60.63 meters. The results obtained for using finials with the same height, hp = 1 meter, require hundreds of finials, while using a combination of finials and towers requires 68 finials. In the case of tower finials with a height hp = 10 meters, additional conductor wires are added or the catenary method is used with 14 conductor wires connecting 28 tower finials with a height of 10 meters, due to the areas outside the protection zone between these 28 final towers, necessitating the addition of conductor wires to expand the protection area of the rolling sphere method to protect the areas of the Tanjungpura University Hospital building.

The Jelekong landfill was a temporary landfill site following a landslide at the Leuwigajah landfill. TPA Jelekong was officially closed at the end of 2005 because it was no longer able to accommodate the increasing volume of waste. However, the impact of activities from the former landfill still has the potential to pollute the environment, especially groundwater sources. The research aimed to identify the physical and chemical parameters of water in the Jelekong ex-landfill case study area and the surrounding area, and to compare the physical and chemical parameters of water between the Jelekong ex-landfill and the landfill that is still operating (Sarimukti landfill). Data were obtained from 4 water sample points and tested using several test methods, namely Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Ion Chromatography (IC), alkalinity, and stable water isotopes. The results showed that the physical characteristics of the Jelekong area generally have a neutral pH with one point having an alkaline pH (JL-02) due to interaction with andesite lithology and the highest DO concentration at point JL-02. While the Sarimukti landfill has a pH value of 7.89-8.27 indicating the result of high bicarbonate concentrations, the TDS value of 15700-18200 ppm indicates the large number of ions and solutes derived from organic and inorganic waste. Piper diagrams show two water facies in the Jelekong area, Ca-HCO3 and Na-HCO3. Sample JL-03 indicates a mixture with landfill leachate due to high Cl and SO4 concentrations. Sample JL-01 still indicates leachate because when compared to the sarimukti sample, the Cl and SO4 concentrations are still quite high indicating a result of both organic and inorganic waste. Stable isotope test results indicated that the water was derived from local precipitation.
