Bioremediasi memanfaatkan aktivitas mikroba untuk mereduksi bahaya limbah menjadi sedikit bahaya atau bahkan menjadi tidak bahaya sama sekali. Limbah oli bekas yang dibuang begitu saja dapat menyebabkan pencemaran air dan pencemaran tanah. Penelitian ini dilakukan untuk mengetahui pengaruh variasi waktu dan penambahan nutrien terhadap penurunan TPH pada tanah tercemar limbah oli. Penelitian dilakukan dalam skala laboratorium selama 28 hari (500 gram) secara buatan. Bioremediasi tanah tercemar limbah oli menggunakan metode biostimulasi dengan pupuk NPK dan pupuk kompos sebagai nutrien. Variasi yang dilakukan adalah pemberian jenis pupuk sebagai nutrien kedalam tanah tercemar (kombinasi pupuk NPK 5% + pupuk kompos 5%, pupuk NPK 10%, pupuk kompos 10% dan sampel kontrol) dan waktu pengujian sampel (hari ke-0, ke-7, ke-14, ke-21 dan hari ke-28). Parameter yang diuji adalah kadar TPH. Hasil penelitian menunjukkan bahwa penurunan terbaik rata-rata di hari ke 14-hari ke 21 yaitu dengan rata-rata penurunan sebesar 8,25%, penambahan nutrisi pupuk NPK 22% + pupuk kompos 19% memberi hasil terbaik dalam penelitian ini yaitu penurunan kadar TPH sebesar 36%.

Detergent waste that is disposed of without prior processing can contaminate the waters so that it interferes with the life of aquatic biota and humans around the waters. Detergent waste treatment needs to be done to minimize this impact, one of which is the adsorption method using coconut shell charcoal. The purpose of this study was to measure the efficiency of reducing the levels of COD, BOD, TSS and pH of detergent wastewater using the adsorption method by coconut shell charcoal. This study used a completely randomized design (CRD) with 1 independent variable factor (charcoal thickness) consisting of 4 levels of treatment, namely control (without charcoal), treatment 1 (100cm thick charcoal), treatment 2 (110cm thick charcoal), treatment 3 (120cm thick charcoal), each treatment was repeated three times. The test parameters (bound variable) in this study were COD, BOD, pH, and TSS. The results showed that the A120 treatment had the best reduction efficiency in reducing COD, BOD, TSS and pH levels to 197 mg/L (75%), 101 mg/L (86%), 35 mg/L (69%) and 7 mg/L. However, this grade value does not meet the quality standards of Permen LHK 68/2016. Based on U Mann Whitney's statistical analysis, it is known that there is no significant difference in the thickness variation of coconut shell charcoal on decreasing levels of COD, BOD, TSS and pH.

The rapid increase in population resulted in the use of non-renewable fossil energy is increasing and its availability is dwindling. So its dependence must be immediately reduced by using renewable alternative energy sources such as biomass energy. This research aims to find out the potential of fruit seeds (durian, mango, jackfruit) as raw materials for making bioethanol, to find out the fruit seeds (durian, mango, jackfruit) that produce the highest levels of bioethanol, and to find out the effectiveness of adding seeding solution to the fermentation process. The research was conducted in the Laboratory of the Faculty of Engineering, Malahayati University, on a laboratory scale (300 ml). The methods used include the pretreatment stage, namely the collection of materials, the hydrolyse stage, namely the addition of a solution of 2.5% H2SO4, the seeding stage of seeding bacteria in yeast with the addition of a solution of brown sugar, the fermentation stage, and the distillation process. The results showed mango seeds provided the best bioethanol levels (4%) compared to bioethanol levels from durian seeds and jackfruit seeds. Yeast tape gives better results than bread yeast.

Salipiger bermudensis (DQ 178660) is one of soil bacterium that produce biosurfactant as a secondary metabolite. It was isolated and identificated for its capacity to utilize the fraction of hydrocarbons. The purpose of this research is to analyze degradation activity of Salipiger bermudensis (DQ 178660) on hydrocarbon contaminated soil. Salipiger bermudensis (DQ 178660) was used as a model to degrade hydrocarbon and it was detected by GC-MS. Adding of fertilizer as a nutrient into soil is believed to enhanced in situ biodegradation by stimulating the growth of bacterium to degrade hydrocarbon contaminated soil. Analysis of Gas Chromatography – Mass Spectroscopy showed that degradation of hydrocarbon by Salipiger bermudensis (DQ 178660) has been successed respectively. It means that Salipiger bermudensis (DQ 178660) was be able to degrade hydrocarbon contaminated soil.

This research was conducted in a school area that has a conventional drainage system that is prone to flooding. To deal with flooding in the area, a new drainage system will be planned. The purpose of this study was to plan the main drainage system at SMKN 1 Kragilan, Serang Regency. The data or information used is primary data obtained from SMKN 1 Kragilan. The data processing method uses manual calculations according to the rational method for calculating rain discharge, and Manning's formula for channel discharge. After the calculation, the dimensions of the economic channel are obtained, because the channel can pass the maximum discharge for a certain wet, rough, and slope cross-sectional area. The main drainage channel is with a base width B = 0.77 m, water level h = 1 m and a height guard w = 0.50 m. The cross section of the channel is rectangular.

Keberhasilan isolasi dan kristalisasi senyawa aktif Bioflokulan-DYT dari tanaman tropis Indonesia, membuktikan tanaman ini berpotensi menjadi bahan baku produksi flokulan alami yang ramah lingkungan. Selama ini penggunaan flokulan dalam pengolahan limbah masih didominasi oleh flokulan sintesis, yang terbukti berdampak negatif terhadap lingkungan. Dengan ditemukannya Bioflokulan-DYT berpeluang menjadi alternatif pengganti flokulan sintetis. Potensi tersebut telah dibuktikan pada penelitian sebelumnya, yang menunjukkan kecenderungan penurunan nilai hantaran molar Bioflokulan-DYT seiring dengan kenaikan nilai konsentrasinya. Untuk memperkuat penelitian sebelumnya, maka dilakukan penelitian lanjutan terkait sifat fisik dari senyawa aktif Bioflokulan-DYT. Salah satunya yang dilakukan pada penelitian ini, yaitu menganalisis kemampuan senyawa aktif Bioflokulan-DYT dengan ion logam yang diukur dari harga konduktivitasnya. Larutan kristal senyawa aktif Bioflokulan-DYT direaksikan dengan larutan ion logam yaitu Ni(NO3)2, Co(NO3)2, dan Ca(NO3)2. Kemudian masing-masing campuran tersebut diuji nilai konduktivitasnya menggunakan konduktometer. Hasil pengukuran dan perhitungan konduktivitas campuran senyawa aktif Bioflokulan-DYT dengan larutan ion logam menunjukkan terjadinya interaksi. Pengaruh panambahan larutan Bioflokulan-DYT pada konsentrasi rendah (250 ppm, 500 ppm dan 750 ppm), mengakibatkan nilai hantaran molar pengukuran lebih tinggi dibandingkan dengan nilai hantaran molar perhitungan. Kondisi ini mengindikasikan senyawa aktif Bioflokulan-DYT dapat berperan sebagai polielektrolit. Sedangkan pengaruh panambahan larutan Bioflokulan-DYT pada konsentrasi tinggi (1000 ppm, 1250 ppm, 1500 dan 1750 ppm), menyebabkan nilai hantaran molar pengukuran lebih rendah dibandingkan dengan nilai hantaran molar perhitungan. Kondisi ini mengindikasikan bahwa senyawa aktif Bioflokulan-DYT berperan sebagai ligan yang dapat berinteraksi dalam pembentukan senyawa kompleks dengan ion logam.
