This research to determine the effect of grinding and addition of activator on biogas production from restaurant foodwaste. Variations that were used in this study is grinded and not grinded. The second variations is by adding Green Phoskko® 0%, 0,1%, 0,25%, and 0,5%. Each variation is load 7 liters substrate. The study was conducted for 30 days. Parameters observed during the study are Chemical Oxygen Demand, pH, temperature, moisture content, Total Solid,Volatile Solid and volume of biogas in manometer. At the end of the study, biogas tested by Gas Chromatography to determine methane gas. The best reactor conditions on producing biogas is substrate with grinded materials and 0,25% of activator added. Materials that grinded has plenty volume of biogas and a fairly methane content. It was showed in the highest cumulative volume of biogas produced by the reactor B1 with a volume of 202.41 mL, methane content 42 μL / 1mL and B3 with a volume of 171.666 mL, methane content 1,12 μL / 1mL. Grinded material and addition of activator has effect but not significant on the biogas production. This occurs because of an imbalance of anaerobic processes caused by the rate of pH decrease. Using of Green Phoskko® as an activator is not enough to provide optimal results.

UKM Jamur Raya is one of the industries that produce oyster mushrooms and is located in the village of Gesikan, Subdistrict of Gantiwarno, Regency of Klaten. The production carried out by UKM Jamur Raya is the manufacture of mushroom seeds until the planting of mushroom seeds in baglog. During the planting process, it will produce waste as a leftover baglog. Baglog waste, if only disposed of, will cause environmental problems and problems for mushroom cultivation. For this reason, it is necessary to treat baglog waste, and when viewed from the content of baglog waste, one thing that can be done is to process baglog waste into compost. The composting method used in this research is vermicomposting, which is making compost by adding worms. There are several factors in composting, one of which is the ratio of C/N values. If the organic matter is still not appropriately decomposed, then the C/N value is large and vice versa. Nitrogen content in baglog waste is very small at 0.6%, so additional materials are needed that can be used as a nitrogen source, one of which is cow dung. The most optimal vermicomposting results are found in the comparison of the composition between baglog waste and cow dung of 5 kg of baglog waste : 2.5 kg of cow dung with a C content value of 0.522%, a N content value of 20.18%, and a C/N ratio value of 20.18%.

Pengolahan air yang tercemar zat warna sintetik paling sederhana dan biaya murah adalah pengolahan secara kimia dengan adsorpsi zeolit. Mengandalkan adsorpsi menggunakan zeolit dalam menurunkan kandungan zat warna sintetis dalam air tidak cukup efektif dikarenakan setiap adsorben memiliki kapasitas penjerapan tertentu. Melihat hal tersebut, adsorpsi dengan zeolit perlu dikombinasikan dengan metode fitoremediasi agar proses penurunan logam berat kromium lebih signifikan. Penelitian ini bertujuan mengetahui pengaruh kombinasi kayu apu (Pistia Stratiotes) dan zeolit terhadap pengurangan warna, COD, TSS pada limbah pewarna sintetik Remazol Red B. Penelitian ini menggunakan empat bak percobaan berbahan dasar PVC (polivinil klorida) vol. 7 liter yang telah disiapkan masing–masing diisi air simulasi cemaran sebanyak 6 liter. Masing-masing perlakukan dilakukan dengan sistem batch dengan perlakuan masing-masing bak yaitu : Perlakuan A menggunakan 0 g kayu apu dan 150 g zeolit, Perlakuan B menggunakan 50 g kayu apu dan 100 g zeolit, Perlakuan C menggunakan 100 g g kayu apu dan 50 g zeolit, serta Perlakuan D menggunakan 150 g kayu apu dan 0 g zeolit. Pengambilan sampel air limbah dari outlet dilakukan setiap setiap tiga hari sekali (hari ke-0,3,6,9,12) sebanyak 600 mL sampai hari ke 12, tanpa penambahan larutan zat warna sintesis Remazol Red Rb. Pengukuran kadar pH dilakukan dengan pH meter, kadar COD diukur dengan menggunakan metode analisis Dichromate Oxidation (SNI 6989.2:2009), kadar TSS diukur dengan metode analisis Gravimetri (SNI 06-6989.3-2004 ), analisis kadar warna menggunakan metode spectrophotometry (APHA Method 8025. Hasil dari penelitian ini menunjukan penurunan zat warna, kadar COD, dan TSS. Penurunan maksimal didapatkan pada hari ke-6 dengan hasil Warna 1216,7 PtCo, TSS sebesar 4,4 mg/L dan COD sebesar 68,73 mg/L. Pada parameter Warna masih melebihi baku mutu limbah sehingga diperlukan pengolahan lebih khusus. Efisiensi penurunan ketiga parameter tertinggi ada pada KA dan KB daripada KC dan KD.
