Abstrak — Water Treatment Plant adalah unit proses pengolahan air yang berada di Pembangkit Listrik Tenaga Uap Palabuhanratu dimana terdapat 4 tahap pengolahan yaitu penyaringan, penjernihan, penghilangan garam dan demineralisasi. Pada proses penjernihan air yaitu pada tanki klarifier nilai kekeruhan berada di atas standar >5 NTU yang melebihi standar Manual Book China Huadian Power Plant Palabuhanratu hal ini menyebabkan beban proses selanjutnya menjadi lebih berat. Penelitian ini bertujuan untuk menentukan nilai optimum koagulan dan flokulan dengan sistem batch eliminasi sampel. Koagulan yang digunakan adalah Poly Alumunium Chlorida dan flokulan yang digunakan adalah Poly Akril Amid. Sampel air laut di analisa sebelum optimasi dan sesudah optimasi dengan turbidity meter, Spektrofotometer Uv-Vis, pH meter dan TDS meter. Hasil optimum didapatkan nilai turbidity/kekeruhan 1.49 NTU dengan kombinasi koagulan PAC dengan dosis 50 mg/L, flokulan PAM dengan dosis 1 mg/L dan kecepatan pengadukan pada 110 rpm.

Inflation is a monetary event that results in a decrease in the value of currency for certain goods. This incident causes disruption to the function of money, distorts prices, destroys output, undermines efficiency and productive investment, and causes social injustice. The method in writing this article is to use a literature study with a descriptive-analytic qualitative approach, namely research that is emphasized on tracing and analyzing. written sources and other reading material related to the theme discussed for further study and in-depth study. This research was conducted to examine inflation and how to overcome it in Islam. Inflation is a condition where there is an increase in prices in general and it takes place continuously. Inflation is also a state of continuous decline in the value of currency. In general, inflation is caused by: the large number of public demand for an item, an increase in production costs, and the very high circulation of money in society. Meanwhile, according to Al-Maqrizi Taqyudin in the Islamic economy inflation is caused by natural inflation (naturally) and human error inflation (by humans). According to its nature inflation is divided into creeping inflation, medium inflation (galloping inflation), high inflation (hyper). inflation). According to the cause of inflation, it is divided into Demand Pull Inflation and Cosh Push Inflation. According to the origin, inflation is divided into inflation originating from within the country and from abroad. Meanwhile, according to public expectations it is divided into Expected inflation and Unexpected inflation. In conventional economies the way to overcome inflation is by implementing monetary policy, fiscal policy, non-monetary / non-fiscal policies. Whereas in Islam inflation is overcome by printing low / minimal amounts of money, implementing the Dues Idle Fund strategy, and implementing fiscal policy.

Subangjaya Village, in Cikole District, Sukabumi City, faces significant air pollution issues that impact the cleanliness of clothing and the health of its residents. This pollution increases the risk of respiratory disorders, especially for those with pre-existing health conditions. To address this issue, this community service program aims to raise awareness about the importance of cleanliness and provide training on making household care products, such as liquid laundry soap and aloe vera-based shampoo. The program targets TP-PKK administrators through educational methods and training, which include distillation techniques, product labeling, and the production of soap and shampoo. The education focuses on the importance of maintaining environmental and clothing cleanliness to reduce the impact of air pollution. This training is expected to improve family skills and economic conditions, as the products created can be used independently or sold, reducing dependence on commercial products. Additionally, the program involves lecturers and students from the Muhammadiyah University of Sukabumi, fostering synergy between academics and the community. The expected outcomes include improved health, skills, and economic conditions for the community, as well as a reduction in the impact of air pollution. This program also supports the achievement of Key Performance Indicators (KPI) by enhancing environmental awareness and collective well-being. Overall, the program contributes to better health, cleanliness, and family economy, as well as an improved quality of life for the residents of Subangjaya.

The biological reaction to tissue damage known as inflammation is typified by the production of mediators including cytokines and prostaglandins. Long-term usage of non-steroidal anti-inflammatory medicines (NSAIDs) can have negative effects, despite their widespread use. This study explores the potential of Terminalia mantaly H. perrier (ketapang kencana), a plant known to contain various bioactive compounds, as a natural anti-inflammatory agent. The aim of this study was to analyze the phytochemical content and evaluate the anti-inflammatory activity of ethanol extracts of T. mantaly leaves using the Bovine Serum Albumin (BSA) protein denaturation method. 70% and 96% ethanol were used in the maceration process for extraction. The 70% ethanol extract included flavonoids, tannins, saponins, triterpenoids, terpenoids, and alkaloids, according to phytochemical screening. With an IC₅₀ value of 27,86 ppm Terminalia mantaly etanol extract 70%, the anti-inflammatory test revealed that the 70% ethanol extract at 400 ppm reduced protein denaturation by 92,29%, which was comparable to the inhibition by sodium diclofenac (84,04% at 50 ppm). These results suggest that polar compounds in the 70% ethanol extract significantly contribute to its anti-inflammatory effect. Therefore, T. mantaly leaf extract demonstrates promising potential as a natural phytopharmaceutical candidate for inflammation therapy.

This study aims to analyze the management of Al-Qur’an memorization (tahfidz) learning at a Quran-based elementary school in Bandung City, focusing on the planning, implementation, and evaluation aspects of the program. This research applied a qualitative case study approach, involving the school principal, tahfidz teachers, students, and parents as informants. Data were collected through observation, in-depth interviews, and documentation, and analyzed using the Miles and Huberman model with data triangulation. The findings indicate that program planning is carried out through annual meetings with tiered memorization targets for each grade, but the involvement of tahfidz teachers in planning remains limited. The tahfidz learning process utilizes talaqqi, tikrar, and murojaah methods, but faces challenges due to limited facilities and low parental support. Evaluations are conducted daily, monthly, and per semester but have not fully accommodated the diverse abilities of students. This study recommends increasing teacher-parent collaboration, improving learning facilities, and adjusting memorization targets to enhance the effectiveness and inclusivity of the program.

Eco-Enzyme merupakan larutan hasil fermentasi limbah organik seperti kulit buah, gula, dan air yang menghasilkan cairan multifungsi ramah lingkungan. Penelitian ini, bertujuan mengkaji potensi kulit buah nanas sebagai bahan baku pembuatan Eco-Enzyme yang dimanfaatkan sebagai pupuk organik cair (POC). Penelitian menggunakan pendekatan kualitatif dengan metode deskriptif-eksperimen melalui teknik observasi dan dokumentasi untuk menganalisis proses fermentasi dan perubahan karakteristik larutan. Fermentasi dilakukan selama tiga bulan dengan rasio 3:1:10 (kulit nanas, gula merah, dan air). Hasil menunjukkan bahwa Eco-Enzyme efektif menyegarkan warna daun tanaman singkong setelah diencerkan dengan air dalam perbandingan 1:10. Selain sebagai pupuk alami, larutan ini berpotensi menjadi solusi pengelolaan limbah dapur yang ramah lingkungan dan ekonomis. Penelitian dilakukan oleh lima mahasiswa PGSD Universitas Djuanda di Kampung Lembur Situ, Cianjur tanpa keterlibatan warga yang mendukung pencapaian Tujuan Pembangunan Berkelanjutan (SDGs) poin 6 (air bersih dan sanitasi layak), 12 (konsumsi dan produksi yang bertanggung jawab), dan 15 (menjaga ekosistem daratan). Temuan ini memperkuat bahwa limbah dapur memiliki nilai guna tinggi jika diolah tepat dan dapat diterapkan sebagai praktik Pendidikan lingkungan berbasis rumah tangga.
