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.

AbstractWastewater has the potential to cause water pollution which causes water quality to decrease due to imperfect sewage treatment, it can cause poisoning in fish and other aquatic biota both from organic waste and accumulation of inorganic heavy metals such as cadmium (Cd), manganese (Mn) and zinc (Zn). Control of water pollution is necessary so that the wastewater complies with the wastewater quality standards based on the Regulation of Permen Lingkungan Hidup RI No.5 (2014) Quality control of each test parameter is carried out by linearity test on wastewater, the value of linear regression correlation coefficient (r) on heavy metals is obtained. Cd, Mn, Zn were 0.9998; 0.9999; 0.9999. In the precision test of the wastewater test sample, the %RSD value was 2.01%, 5.21%, 2.58%. The %recovery values were 100.98%, 100.00%, 99.99%. The results of research showed the Cd, Mn and Zn metal using a spectrometer Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) Cd metal content in wastewater is 0.0070- 0.0504 (mg/L), Mn metal content is 0.0661 -0.9270 (mg/L), and Zn metal content 0.1823-1.1202 (mg/L).

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.

Indonesia has various sources of graphite in large quantities. One of them is palm oil waste. Palm oil is a horticultural crop that acts as the largest non-oil and gas foreign exchange contributor in Indonesia. This study aims to synthesize graphite from oil palm trunks with a catalyst through the pyrolysis method. This is an experimental research which eventually generated qualitative data to be analyzed. Oil palm trunks are dried in the sun, then crushed into powder with a grinder and sieved to 200 mesh. Graphite was synthesized using a carbonization step at 500°C. Impregnation using 3M ferric chloride (FeCl3), with a concentration variation of 10% and 30%. Further activation at a temperature of 900°C for 3 hours. The results synthesis of graphite powder were washed with hydrochloric acid (HCl) and distilled water repeatedly to obtain relatively pure graphite. Graphite characterization includes Fourier Transform Infrared Spectroscopy (FTIR). The results of FTIR analysis showed that graphite contains functional groups O–H, C–H, C–O, C?C, and C=C.
