Increased population growth must be followed by the availability of clean and healthy water. This research is to find out the amount of water needs of PDAM customers for South Cikarang and Cibarusah areas. The purpose of this paper is to find out the clean water needs of customers of PDAM Tirta Bhagasasi South Cikarang Branch in 2020 and find out the increase in population and number of customers and how much those needs are. So that PDAM Tirta Bhagasasi can serve the community at present and in the future for its distribution evenly, so that the community can obtain clean water smoothly. From the analysis using the realization of needs analysis, it is obtained the need for clean water for customers of PDAM Tirta Bhagasasi, Cikarang Selatan Branch for 2020, amounting to 394, 5 liters / second. Estimated clean water debit needed for 2020 in the Cibarusah region is Q = 169.1 liters / sec. The volume of additional customers for 2020 South Cikarang and Cibarusah Branches is 0.283 m3 / second. With this debit, it is possible to add 31,067 customers to PDAM Cikarang Selatan Branch. In the analysis of the pipe capacity for the next five years 2020 for the South Cikarang Branch the dimension of the pipe is still able to flow water from the Tegal Gede reservoir to the villa Mutiara reservoir.

Plastik LDPE merupakan salah satu jenis plastik sintetis yang sulit terurai di lingkungan. Proses pirolisis sampah plastik merupakan proses dekomposisi senyawa organik yang terdapat dalam plastik melalui proses pemanasan dengan sedikit atau tanpa melibatkan oksigen. Pada proses pirolisis senyawa hidrokarbon rantai panjang yang terdapat pada plastik dapat diubah menjadi senyawa hidrokarbon rantai pendek dan dapat dijadikan sebagai bahan bakar alternatif. Penelitian ini bertujuan untuk mengetahui pengaruh suhu terhadap perolehan minyak hasil pirolisis, mengetahui pengaruh suhu dan jenis plastik terhadap sifat fisik dan sifat kimia dari minyak hasil pirolisis. Pirolisis sampah plastik ini dilakukan dengan umpan yaitu sampah plastik jenis LDPE (Low Density Polyethlene). Proses pirolisis dilaksanakan selama 60 menit dengan variasi suhu 200Â°C, 300Â°C, 400Â°C, 500Â°C dan 600Â°C. Minyak hasil pirolisis terbanyak dari sampah plastik LDPE diperoleh pada suhu operasi 600Â°C sebanyak 90 ml. Viskositas minyak hasil pirolisis mendekati nilai viskositas dari bensin. Densitas minyak hasil pirolisis mendekati nilai densitas dari solar dan minyak tanah. Nilai kalor minyak hasil pirolisis mendekati nilai kalor dari solar dan minyak tanah.

Entering the industry 4.0 stage, more industries are developing in Indonesia, one of which is PT Puradelta Lestari. PT Puradelta Lestari as a developer of the Deltamas city area that serves industrial, commercial and residential customers produces industrial liquid waste. Preliminary studies have shown that the ammonia content of wastewater in the PT has exceeded the threshold of 25 mg / L amonia. This study aims to determine the effect of adding activators to activated carbon from coconut shells with variations of immersion time on decreasing total ammonia levels in wastewater at PT. Puradelta Lestari. Activation of activated carbon is carried out with activators HCl, NaCl, and KOH with a concentration of 4%, with a volume ratio of activator 1: 6 and variations in the immersion time for 12 hours, 16 hours, 20 hours, 24 hours. The optimum condition was obtained at the time of immersion with KOH activator for 24 hours obtained a decrease in ammonia levels that is equal to 87.6%.

Efek Penggunaan Iradiasi Microwave Dalam Pembuatan Biodiesel Minyak Nyamplung (Calophyllum Inophyllum Linn) Nisa Nurhidayanti

Abstrak Penggunaan biodiesel dilakukan untuk menggantikan penggunaan bahan bakar fosil yang persediaannya semakin berkurang. Bahan baku biodiesel yang baik menggunakan bahan non pangan sehingga penggunaannya tidak berkompetisi dengan kebutuhan pangan. Nyamplung (Calophyllum inophyllum Linn) adalah satu tanaman nonpangan yang berpotensi menghasilkan randemen biodiesel yang tinggi. Minyak nyamplung dalam penelitian ini memiliki kandungan FFA sebesar 27,498%, oleh karena itu diperlukan proses pretreatment yang terdiri dari degumming untuk menghilangkan getah, esterifikasi dan netralisasi untuk menurunkan FFA < 2% agar minyak dapat dilanjutkan pada proses transesterifikasi. Tujuan penelitian ini untuk mengkaji pengaruh daya microwave, waktu dan suhu reaksi terhadap yield biodiesel. Transesterifikasi dilakukan dengan menggunakan variasi daya (100, 200 dan 400W), variasi waktu (5, 7, 10, 12 dan 15 menit) dan variasi suhu (50, 55, 60, 65 dan 70 oC). Hasil penelitian menunjukkan kondisi terbaik menggunakan power microwave 200W pada suhu 65 oC selama 5 menit, yield biodiesel maksimal sebesar 84,62% dan sifat fisik biodiesel telah memenuhi standar SNI 04-7182-2006, ASTM 6751-02 dan EN-14214. Hasil penelitian menunjukkan penggunaan iradiasi microwave dapat mengurangi waktu reaksi transesterifikasi menjadi 1/6 kali lebih cepat dibandingkan metode konvensional. Kata kunci: Efek, biodiesel, microwave, minyak nyamplung

PENGELOLAAN LIMBAH B3 PT YTK Indonesia Nisa Nurhidayanti; Cici Arinih

PT. YTK Indonesia is one of the automotive industries in Indonesia that does not yet have a permit related to processing hazardous and toxic waste, so that the resulting hazardous and toxic waste is handed over to third parties for further processing. The presence of hazardous and toxic waste produced from various production activities requires special attention, because the losses that will be caused if the waste is not managed and not properly treated. The purpose of this study was to determine the type of hazardous and toxic waste and hazardous and toxic management produced and to assess the suitability of hazardous and toxic waste management with Government Regulation No. 101 of 2014. Data analysis was carried out by conducting a literature study of the research objects and basic concepts of hazardous and toxic waste management systems. hazardous and toxic wastes produced are used drums, used buckets, contaminated mounds, contaminated cloth gloves, iron scrab, grinding sludge, contaminated wood powder, aluminum powder, NG parts, waste material, contaminated gloves, used oil, and domestic hazardous and toxic waste. Hazardous and toxic waste Management carried out includes reduction, storage, storage, internal transportation, external transportation and utilization. The processing of hazardous and toxic waste is left to a third party, namely PT. Menembus Batas Langit and PT. Karya Nusa Bumi Persada. All hazardous and toxic waste management processes at PT. YTK Indonesia as a whole has complied with government regulations, but there is a discrepancy with PP No. 101 of 2014 which is about hazardous and toxic waste packaging that does not have labels and symbols and there is a storage area for hazardous and toxic waste that has rust.

Waste water analysis that has been done for PT. Puradelta Lestari has exceeded the ammonia threshold of 25 mg / L. The research objective was to determine the effect of activated carbon by determining the optimum size, optimum time, optimum thickness, and efficiency needed by activated charcoal in reducing ammonia levels of liquid waste. The research method uses a quantitative descriptive approach. The results of the study prove that activated carbon can absorb ammonia in wastewater quite well, from the research that has been done, to determine the optimum condition of activated carbon in absorbing ammonia by varying the mesh size (0.1 mm, 0.25 mm and 0.5 mm) , Media Height (20%, 25%, 30%, 35% and 40%), detention time (10, 15, 20, 25 and 30) minutes in decreasing ammonia, the optimum condition obtained at Mesh size is 0.25mm with Efficiency 78.6%, Media Height at 40% with Efficiency 67.6%, contact time 20 minutes with Efficiency of 78.6%.
