Abstract

Ramuak cracker is one of the main product of Toboh Mandailing, Balai Baru, VII Koto Sungai Sariak, Padang Pariaman, West Sumatera. One of the obstacles faced by the cracker industry players is the amount of used cooking oil produced. Used cooking oil is leftover frying oil that has been repeatedly used. If it continues to be consumed, it will be harmful to health. If discharged into the environment, it will cause environmental pollution. Therefore, the Community Partnership Program Team of the Politeknik ATI Padang provided counseling about the dangers of used cooking oil and efforts to process used cooking oil into something useful, namely producing bar soap with used cooking oil as its raw material. The step of making bar soap from used cooking oil is to slowly dissolve the NaOH solution into 500 grams of used cooking oil, then stir using a stainless steel stirrer until evenly distributed and there are no more lumps. The next step is to add dyes and fragrances and stir again to form a soap mixture. Do the printing of the soap dough in the mold by coating it with parchment paper. Let stand for 24-48 hours until the saponification process is complete. PKM activities carried out well and smoothly and in accordance with the expected results. Each participant was able to make bar soap from used cooking oil very well. This activity is expected to provide insight, knowledge and input to partners regarding the process of making bar soap from used cooking oil so that it can be used for daily needs and can even be sold as an additional source of income for the community.

Abstract

Soffell is a mosquito repellent product in the form of lotions and sprays. Soffell can be used to protect the body from mosquito bites with an effective protection of up to 8 hours because it contains DEET in it. Determination of the level of DEET active substances in Soffell Spray products used the gas chromatography method. Gas chromatography is a method of separating a mixture into its constituent components based on the interaction of the stationary phase and the mobile phase. The stationary phase used is the dimethyl polysiloxane column while the mobile phase is N2 gas. N2 gas used because it is inert (does not react with analytes) is also easily obtained and inexpensive. In this gas chromatography, the column used is the RTX-1 column which contains dimethyl polysiloxane. The injection system used is a split injector for samples that have high concentrations. The incoming sample volume is only what is needed while the remainder is discarded. The detector used is FID (Flame Ionization Detector) so it requires H2 gas as a combustion gas and O2 as an oxidizer to produce a flame. DEET active substances levels obtained from Soffell Spray products are Soffell Spray Geranium 12.815 %, 12.518 %, 12.543 % and Floral Spray 11.900 %, 12.043 %, 12.067 % respectively. The analysis results obtained from Soffell Spray products are still included in the standard company specifications are for Soffell Geranium Flowers 11.97-13.78 % and Floral Spray 11.05-12.72 %.

Abstract

Coal is one of the fossil fuels which in general are sedimentary rocks that can be burned, formed from organic deposits, mainly are plant remnants and are formed through coalification processes. Coal has each characteristic that is different from each other depending on the level of the coal itself. The quality of coal is the nature of the physical and chemical properties of coal which affect its potential usefulness. Parameters used to determine coal quality include calculating water content, ash content, levels of flying and fixed carbon substances. From the test results of coal samples carried out the value of the water content can range from 6.26-12.42 %: ash content values obtained 3.06-7.87 %; the value of the flying substances obtained 36.94-44, 23% and the fixed carbon values obtained ranged from 41.96 to 48.86% with a standard water content of 1.29-21.66 %, ash content of 2.93-16.73 %; flying substance levels of 22.38-46.42 % and fixed carbon 37.8-98% . From the analysis data, it can be concluded that the water content, ash content, and flying substances contained in the sample have met the standards of the ASTM (American Society for Testing and Materials) used by PT. Coal Mine Bukit Asam (Persero) Tbk, Tanjung Enim.

Abstract

Research on dissolution determination of Ketoprofen compounds by Spectrophotometry. Ketoprofen is a non-steroidal anti-inflammatory drug compound (NSAID) that works as an anti-inflammatory. Anti-inflammatory here is a group of drugs used to reduce inflammation and relieve pain. The dissolution test is a method used to determine the content of active compounds that dissolve in drugs, where the time, temperature and media are set according to the human stomach and intestines, and can find out how much the content of active compounds dissolves in the human intestines and stomach. This dissolution test, then the ketoprofen drug is read by spectrophotometry. Test the dissolution by spectrophotometer at a wavelength of 260 nm using HCl 0.1 N and buffer pH 7.4. The results of the determination of the dissolution test of the active substance on ketoprofen at the acid stage obtained an average of 0.009% and at the pH 7.4 buffer stage obtained an average content of 86.4155%. It can be concluded that the determination of the ketoprofen dissolution test in the sample meets the requirements (MS), in accordance with the specifications of the Internal Standard of PT Novell Pharmaceutical Laboratories, namely at the acid stage not more than 10% of ketoprofen dissolved in 2 hours, and at the pH 7.4 buffer stage it has a requirement of 75%. ketoprofen dissolved in 45 minutes. In the dissolution of acidic media, 0.1 N HCl is used because its condition resembles that of the stomach.

Abstract

Research on determination of Profenofos Pesticide Residue Levels on Agafha Tomatoes Using Gas Chromatography Method has been carried out. The purpose of conducting research on samples of tomatoes that are often consumed by the community is to find out whether the tomato plants are suitable for consumption by the community or whether they have a negative impact if consumed frequently and to find out whether the tomato samples reach the maximum residue limit that has been set. After analyzing the Agaftha tomato samples in the pesticide laboratory, data was obtained that the Agaftha tomatoes contained prefenofos pesticide residues with a concentration of 0.0805 mg/kg, and the results of this test stated that the Agaftha tomato samples could be consumed properly because the concentration did not exceed the maximum residue limit. Prefenofos residue is regulated in the Regulation of the Minister of Agriculture of the Republic of Indonesia Number 55/PERMENTAN/KR.040/11/2015. The maximum residue limit (BMR) for the active ingredient profenofos is 10 mg/Kg. Hence, it can be concluded that the Agaftha tomato sample is suitable for consumption because the concentration of residue levels in the Agaftha tomato sample is lower than the BMR which has been regulated in the Regulation of the Minister of Agriculture of the Republic of Indonesia.

Abstract

This study aims to determine a suitable medium for the growth Trichoderma harzianum. The treatments tested were rice media (M1), bran media (M2), corn media (M3), potato media (M4), and rice husk mixed media (M5). The parameters observed in this study were the quality test of conidia density using a microscope and haemacytometer, macroscopic observation of the media for 7 days and microscopic observation of the media to evaluate the media that had the best effectiveness as a medium for propagation of Trichoderma harzianum. The initial isolate of Trichoderma harzianum used had a conidia density of 2,9x109conidia/ml. The results showed that the propagation of Trichoderma harzianum in various media affected the macroscopic, microscopic and conidia density changes of Trichoderma harzianum. Trichoderma harzianum can grow on all treatment media. The bran media is the medium with the highest conidia density compared to other media.
