    The CAT Jakarta is a critical water resource that extends across several provinces in Indonesia, covering DKI Jakarta, Banten, and West Java. This basin comprises both recharge and discharge areas that support human settlements and various economic activities. The recharge area in CAT Jakarta covers 321.4 km2 and is densely populated, raising concerns about groundwater contamination. The study used the DRASTIC method to assess groundwater vulnerability, with seven parameters: Depth to Water Table (D), Net Recharge (R), Aquifer Media (A), Soil Media (S), Topography (T), Impact of the Vadose Zone (I), and Hydraulic Conductivity of the Aquifer (C). The vulnerability index obtained that 36.51% of the research area has a low vulnerability level, with values ranging from 101 to 119. The remaining 63.49% has a medium level of vulnerability, with values ranging from 120 to 157. These results suggest that the CAT Jakarta recharge area is at risk of contamination from pollutants with low to moderate intensity. Therefore, it is crucial to monitor and regulate activities that involve the use of groundwater in the area to prevent contamination. This study can guide policymakers and stakeholders in implementing effective management strategies for sustainable groundwater utilization in the CAT Jakarta basin

    Pada masa pandemi, kesehatan itu penting. Mandi uap dengan rebusan rempah di sauna dipercaya dapat meningkatkan kekebalan tubuh dan memperlancar pernapasan. Namun pada umumnya heater di sauna memiliki daya yang sangat besar dan masih menggunakan sumber dari PLN, sehingga penggunaannya dapat menimbulkan biaya listrik yang cukup tinggi. Untuk menekan biaya yang tinggi dapat dimanfaatkan energi alternatif yaitu energi surya. Dengan keluaran PV yang tidak linier sehingga tidak dapat menghasilkan daya yang maksimal, maka dapat menggunakan metode yang disebut maximum power point tracking (MPPT) yang digunakan untuk mencari titik daya maksimum sehingga akan meningkatkan efisiensi daya keluaran pada PV. Oleh karena itu, akan dibuat alat optimasi daya (MPPT) dengan menggunakan metode kendali logika fuzzy untuk mengendalikan DC-DC Cuk Converter. MPPT kontrol logika fuzzy disimulasikan menggunakan MATLAB dengan 2 kondisi yaitu menggunakan 3 fungsi keanggotaan dan 7 fungsi keanggotaan. Didapat hasil bahwa penggunaan 3 Mf hanya dapat meningkat sebesar 97,5% sedangkan penggunaan 7 Mf meningkatkan nilai daya maksimum sebesar 99% pada iradiasi 1000 W/m2, yang mana menghasilkan daya keluaran mendekati daya maksimum pada spesifikasi pada PV
