Abstract Traditional medicine such as saffron-colored rice is still in great demand in Indonesia. If the production process is not carried out in accordance with the method of making and processing herbal medicine, it can cause microbial contamination. The preparation of herbal medicine must meet the requirements for the Total Plate Number (ALT). The aimof this study was to determine the amount of microbial contamination in the liquid herbal rice kencur which is produced by the traveling herbal medicine seller. The study used an experimental method using samples of saffron-colored rice (A, B, and C). Microbial testing went through the stages of homogenization, dilution, mixing with the mediumsnd incubation. Homogenization was initiated by adding 25 ml sample with 225 ml 0.1% Buffered Peptoned Water with a stomacher for 2 minutes. Suspension dilution was carried out in order to obtain colonies that grew separately so that they were easy to count. Mixing with the medium is done by pour plate inoculation method. The solid medium used for ALT is Nutrient agar. Based on the results of the study, the ALT results were obtained, sample A 2.2 x 104 colonies/ml, sample B 2.6 x 104 colonies/ml, and sample C 8.0 x 107 colonies/ml. The results are not in accordance with the requirements stated in the Regulation of the Head of the Drug and Food Control Agency of the Republic of Indonesia Number 12 of 2014 about Quality Requirements for Traditional Medicines.AbstrakObat tradisional seperti jamu beras kencur masih banyakdiminati di Indonesia.

Terbinafine hydrochloride is a synthetic allylamine drug with a broad spectrum of antifungal properties. The purpose of this study was to identify terbinafine hydrochloride in whitening cosmetic products using High Performance Liquid Chromatography (HPLC). The first stage starts with dissolving cosmetic samples (A, B, C) and blanks, diluted with 25 ml of methanol. Then the solution was vortexed for 2 and centrifuged for 10 minutes at 4000 rpm. The supernatant layer formed was filtered through a 0.45 m membrane filter. Then the filtrate obtained was tested by the HPLC method. Based on the results of the system suitability test of the sample and blank, the concentration was 16????????/ml, the average retention time was 8.934 minutes and the average area was 2163340. The standard deviation of the relative retention time was 0.3098% and the area was 0.0721%. The follow-up factor and theoretical plate obtained automatically from the HPLC tool obtained an average follow-up factor value of 0.9515 and an average theoretical plate value of 217.7531. The results of the HPLC system suitability test and the terbinafine hydrochloride blank were identical, but the retention time was different, obtained from each different sample. All cosmetic samples contained Terbinafine hydrochloride as they did not meet the requirements. Regulation of the Minister of Health of the Republic of Indonesia Number 3 of 2021.

The high value of COD (Chemical Oxygen Demand) is one of the indicators of the burden of organic substance pollution in the wastewater food flavoring industry. COD values can be lowered by converting to biogas. In this study biogas was made through a two-stage fermentation system. At the first stage organic material is conditioned in an acidic state (pH = 4) with variable fermentation time: 2 days, 4 days, 6 days and 8 days. Then at each time fermented for 18 days at second stages. As a result, the amount of biogas volume produced is the same, namely: 7,5 L. However, the most amount of methane is produced at the time of fermentation phase one for 2 days, namely: 83%. While the lowest value is produced at the time of fermentation phase one for 8 days, namely: 70%. At the time of fermentation phase one for 8 days produced the highest hydrogen composition, namely: 9,023 %. The composition of methane at stage one for 4 days produces a higher value, namely: 81.431% compared to the single stage fermentation system, namely: 78.9 %.

Activated charcoal of Arabica coffee grounds with different activators (HCl and H3PO4) has the potential as an adsorber for chromium in artificial textile waste. Coffee grounds can be used as raw material for activated charcoal because it has a fairly high carbon content. Waste is made using Chromic Acid powder with a ratio of 1:10 to Aquadest. The concentrations of HCl and H3PO4 activators used were respectively 0.1 N. Activated charcoal is made by drying coffee grounds for 24 hours and the carbonization process is carried out in a furnace at a temperature of 200 oC. Charcoal formed is activated with HCl and 0.1 N H3PO4 activator for 48 hours. The characteristics tested were ash content, water content, absorption of iodine, and absorption of chromium solution. The chromium absorption test used AAS (Atomic Absorption Spectrophotometry) and SEM-EDX (Scanning Electron Microscope - Energy Dispersive X-Ray) tests. The results showed that Arabica coffee grounds had the potential as chromium adsorbent and the best activator used was HCl with the characteristics of activated charcoal as follows: water content of 8.1175%, ash content of 4.5981%, absorption of iodine of 401.7964 mg /g and the absorption capacity of chromium solution is 800 mg/g.
