One of domestic wastewater treatment in Bogor City is by using communal WWTP (Wastewater Treatment Plant) system. The communal WWTP treats domestic wastewater with an anaerobic baffled reactor configuration (ABR). This study aims to determine the effluent quality of communal WWTP so that it can be used as reference for related institutions in managing communal WWTP. The effluent from 3 communal WWTPs namely KSM Amanah, Rosella, and Cipendek Indah measured the content of TSS, COD, oil and grease, ammonia, and total coliform. The secondary data of effluent from 40 communal WWTP were obtained from Environment Agency of Bogor City. The result of the effluent analysis is compared with the Minister of Environment and Forestry Regulation No. P.68/2016 on the Quality Standard of Domestic Wastewater. The study showed that the total coliform parameter did not meet the quality standard in 3 communal WWTP locations, COD exceeded the quality standard in KSM Rosella and Cipendek Indah, and TSS above the quality standard in KSM Cipendek Indah. The communal WWTP in Bogor city has not been effective in reducing the pollutant content in domestic wastewater especially BOD and total coliform. The communal WWTP management needs to be improved in order for better effluent.Keywords: domestic waste, communal WWTP, effluent, quality standard, bogor cityABSTRAKSalah satu pengolahan air limbah domestik di Kota Bogor yaitu menggunakan sistem IPAL komunal. IPAL komunal mengolah air limbah domestik dengan konfigurasi anaerobic baffled reactor (ABR). Penelitian ini bertujuan untuk mengetahui kualitas efluen IPAL komunal di Kota Bogor sehingga dapat dijadikan acuan bagi instansi terkait dalam mengelola IPAL komunal. Efluen dari  3 IPAL komunal yaitu KSM Amanah, Rosella, dan Cipendek Indah diukur kandungan TSS, COD, minyak lemak, amonia, dan total coliform. Data sekunder efluen  dari 40 IPAL komunal diperoleh dari Dinas Lingkungan Hidup Kota Bogor. Hasil analisis efluen tersebut dibandingkan dengan baku mutu PermenLHK No. P.68/2016 tentang Baku Mutu Air Limbah Domestik. Penelitian menunjukkan bahwa parameter total coliform tidak memenuhi baku mutu di 3 lokasi IPAL komunal yang diteliti, COD melebihi baku mutu di KSM Rosella dan Cipendek Indah, serta TSS diatas baku mutu teridentifikasi di KSM Cipendek Indah. IPAL komunal di Kota Bogor belum efektif dalam menurunkan kandungan polutan dalam air limbah domestik terutama BOD dan total coliform. Pengelolaan IPAL komunal perlu ditingkatkan agar kualitas efluen yang dihasilkan lebih baik. Kata kunci: limbah domestik, IPAL komunal, efluen, baku mutu, kota bogor

Pijat merupakan salah satu metode pengobatan tertua di dunia. Pijat meliputi seni perawatan kesehatan dan pengobatan yang mampu melemaskan sendi yang terlalu kaku dan menyatukan organ tubuh dengan gosokan yang kuat. Penelitian ini bertujuan untuk mengetahui pengaruh pijat bayi terhadap berat badan bayi pada umur 2-6 bulan pada kelompok perlakuan dan kontrol. Metode penelitian ini adalah quasi experiment dengan  non equivalen kontrol design yang terdiri dari 30 bayi yang berumur 2-6 bulan yang terdiri dari 15 sebagai kelompok intervensi dan 15 sebagai kelompok kontrol. Teknik pengambilan sempel menggunakan teknik purposive sampling. Data dianalisa menggunakan paired t-test dan Independen t-test. Hasil penelitian menunjukan bahwa ada efek pijat bayi dengan peningkatan berat badan bayi. diperoleh  p value (0,029) < 0,05.  Dapat disimpulkan bahwa ada pengaruh berat badan bayi setelah dilakukan pemijatan. Hasil penelitian ini diharapkan dapat meningkatan pengetahuan pada ibu tentang pentingnya pijat bayi untuk meningkatkan berat badan bayi.

Innovations in the biofiltration process can provide effective solutions to overcome crucial water pollution problems. The elimination of pollutants is a result of the combined effects of biological oxidation, adsorption and filtration processes. This research aims to evaluate the performance of quartz sand biofiltration for removing total suspended solids, turbidity, color, organic matter, and ammonium from polluted river water and develop an empirical model for designing quartz sand biofilters for the treatment of polluted river water. Experiments were conducted using two biofilter units filled with quartz sand as filter media. A set of experiments were performed to evaluate the effect of hydraulic retention time on biofilter performance in removing water contaminants. The kinetics of organic matter removal were also determined to describe the performance of the biofilter. The results show that biofiltration can significantly remove river water pollutants. Removal efficiency depends on the applied hydraulic retention time. At a hydraulic retention time of two hours, removal efficiencies of total organics, ammonium and total suspended solids were up to 78%, 82%, and 91%, respectively. A model for designing quartz sand biofiltration has been developed from the experimental data.

Indonesia, as the largest palm oil producer in the world, also produces palm oil mill effluent (POME). While the latter is a liquid waste that is hazardous for the environment, with proper processing, it can be a potential energy source. The objective of this study was to study the performance of biogas production from POME at various temperatures. The POME and sludge mixture was fermented, according to the treatment, at 27-28
