Abstract

Nitrogen dioxide (NO2) contributes greatly as a precursor to a number of harmful secondary air pollutants including nitric acid, the nitrate portion of secondary inorganic aerosols and oxidants including ozone. Nitrogen dioxide gas (NO2) is an ambient air pollutant along with the element nitrogen monoxide (NO) which is usually produced from human activities such as burning vehicle engine fuel, burning rubbish, burning coal and industry. This research aims to monitor the quality of air pollution in industrial areas in East Jakarta. The NO2 content in the air can be determined using the UV-Vis spectrophotometer method based on SNI 7119-2: 2017. The principle of NO2 testing uses a UV-Vis spectrophotometer based on SNI 7119-2: 2017. From the results of the tests carried out, it can be concluded that the NO2 level obtained in sample 1 was found to be 25,153 µg/Nm3, in sample 2 the NO2 level was 28,371 µg/Nm3, in sample 3 the NO2 level was 107,022 µg/Nm3, in sample 4 the NO2 level was 29,720 µg/Nm3. Nm3, and in sample 5 the NO2 level was 83.446 µg/Nm3. Based on PP RI No. 22 attachment VII of 2021 concerning air pollution control, the quality standard for NO2 is 200 µg/Nm3 for 1 hour. So it can be concluded from the results of the tests that have been carried out that the NO2 levels in the environment are still below the quality standard, which means that it is not a source of NO2 pollution, is safe and meets the requirements for human health and the environment.

Abstract

The development of the food and beverage industry has led to an increasing demand for the availability of liquid sugar. To ensure the hygiene of liquid sugar products, quality control is necessary, one of which is through microbiological analysis. This study aims to identify the presence of Salmonella sp. in liquid sugar produced by PT XYZ using microbiological and genetic analysis methods. The methods applied include bacterial inoculation on Xylose Lysine Deoxycholate (XLD) agar as a specific medium and Real-Time Polymerase Chain Reaction (RT-PCR) to detect bacterial DNA. The results showed no color changes in the XLD medium that would indicate the presence of Salmonella sp. Additionally, the RT-PCR results did not show amplification in the samples, except for the positive control. This indicates that the tested liquid sugar products are free from Salmonella sp. contamination, demonstrating the effectiveness of good sanitation and storage practices during production.

Abstract

Palm oil mill effluent can pollute the environment and endanger human health. Test parameters that can indicate the quality of palm oil mill effluent are pH, Chemical Oxygen Demand, and Total Suspended Solid. The purpose of this study is to determine the pH using pH meter, COD and TSS values using spektrofotometer UV – Vis in each palm oil mill effluent pond before discharging into the river so as not to pollute the environment. The results of three weeks of testing showed that the pH value of the palm oil mill effluent pond tended to increase from the fat fit pond to the outlet of pond V while the COD and TSS values tended to decrease from the fat fit pond to the outlet of pond V. The pH value of the waste discharged into the river is in the range of 6-9, the COD value is below 350 mg/L and TSS is below 250 mg/L. The results obtained are in accordance with the regulation of the Minister of Environment Number 5 of 2014.  The resulting palm oil mill effluent is safe to be discharged into the river.

Abstract

Curcuma can be used to maintain and improve body health as well as treat disease. Instant powdered curcuma drink is one of the curcuma plant's processed products.People in the Lubuk Minturun Koto Tangah District, Padang City have natural and human resources that can be utilized through training programs for creating instant powdered curcuma. This exercise drew a total of 25 women, including housewives and teenagers. There are three steps to this community service activity: lectures, demonstrations, and practice. Because the production method is simple and the tools and materials required are readily available, more than 90% of the participants in this activity were able to comprehend the process of making instant powdered curcuma. It is intended that by participating in this activity, the community would be able to increase entrepreneurial prospects and so boost the economy.

Abstract

Pemanfaatan alat pengeringan ikan tanpa sinar matahari telah banyak dikembangkan dan terbukti dapat menghasilkan produk ikan kering yang kualitasnya sama dengan ikan kering hasil pemgeringan sinar matahari, bahkan beberapa produk menunjukkan produk yang lebih baik. Melakukan pengawetan ikan dengan pengeringan menggunakan alat pengering ikan yang menggunakan bahan bakar Biomassa. Hasil pengeringan menghasilkan ikan kering yang lebih higienis dan mempunyai cita rasa tinggi. Hasil tangkapan ikan dari masyarakat nelayan diharapkan mempunyai nilai jual yang tinggi. Oleh karena itu, untuk mengatasi permasalahan mitra sasaran dalam hal produksi ikan teri kering, maka tim pelaksana pengabdian akan melatih mitra sekaligus menerapkan teknologi pengeringan ikan menggunakan alat pengering ikan alternatif tanpa menggunakan sinar matahari. Kegiatan ini dilakukan pada kelompok tani nelayan di Kel. Pasia Nan Tigo Kec. Koto Tangah. Pelaksanaan kegiatan mencakup berupa Motivasi Usaha, Pelatihan Manajemen Usaha, dan Training penggunaan Alat Pengering.

Abstract

Shortening is a solid plastic fat product that is widely used as a raw material in the production of food products such as biscuits, cakes, bread, and pastries. PT X produces shortening from the interesterification reaction of Refined, Bleached and Deodorized Palm Oil. (RBDPO). In the shortening production process using the interesterification method, it will be influenced by the amount of catalyst added and the heating time. The objective of this research is to analyze the effect of the amount of sodium methoxide catalyst and heating time on the interesterification process of RBDPO on the quality of shortening products. By considering the parameters of Solid Fat Content (SFC) and Slip Melting Point (SMP), an optimal method can be developed to improve the quality and stability of the shortening product. The variations of sodium methoxide catalyst used are concentrations of 0.050%; 0.100%; 0.125%; 0.25%; 0.375%; 0.500%, while the variations in heating time are 50 minutes, 40 minutes, and 30 minutes. The results of the research conducted show that the interesterification process of RBDPO into a shortening product with very good quality is achieved by using sodium methoxide catalyst with a concentration of 0.250% and a heating time of 40 minutes, in accordance with the standards set by PT X for Solid Fat Content (SFC) and Slip Melting Point. (SMP).

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.
