Abstract

Nitrates are used as fertilizer to fulfill nutrients for plants. Anodic plasma electrolysis technology can be an effective and environmentally friendly solution in nitrogen fixation into nitrate compounds. This research aimed to determine the effect of controlling voltage and power in nitrate synthesis using plasma electrolysis with air as the raw material injected at the anode. The material used is an electrolyte solution of 0.02 M K2SO4, the electrodes used are in the form of tungsten and stainless steel, and a nitrate reagent is used for the nitrate test. The results of the study showed that at 400 W, the optimal rate was 0.8 L men-1 with 1889 mg L-1 of nitrate formed. While at 500 W and 600 W, the optimal rate of 1 L men-1 with nitrate formed was 2213 mg L-1 and 2453 mg L-1. The emission intensities of reactive species N, N2*, N2+,•OH, •H, and •O at an optimal rate of 0.8 L men-1 400 W 700 V in 20139 au, 28540 au, 18023 au, 30863 au, 12547 au, 49800 au. The addition of air injection will increase the oxygen input into the plasma zone, which can produce reactive species •O and nitrogen produces reactive species N, N2*, N2+ forms NO. The formed NO compounds can be oxidized to NO2, and the reaction between NO2 and reactive species •OH forms nitrates.

Abstract

Salah satu kewajiban seorang guru adalah membuat karya ilmiah dan mempublikasikannya melalui jurnal atau seminar baik nasional maupun interasional. Namun masih banyak guru yang tidak punya keterampilan dalam penulisan karya ilmiah, sehingga kegiatan pegabdian ini bertujuan untuk memberikan pelatihan penulisan karya ilmiah agar guru dapat menulis dengan baik bahkan mempublikasikannya melalui jurnal. Sasaran dari kegiatan pengabdian ini adalah 25 guru SDN Negeri Pudak Payung 01 Semarang. Kegiatan dilakukan melalui tiga tahap yaitu, observasi dan koordinasi pada mitra, pelatihan penulisan karya ilmiah, monitoring dan evaluasi kegiatan pengabdian peningkatan tingkat pemahaman peserta, yang diukur oleh tim melalui instrumen pretes dan posttes. Sebelum program dijalankan, tingkat pemahaman peserta mengenai penulisan hanya mencapai 20%, namun setelah program berjalan, angka tersebut melonjak tajam menjadi 95%. Pemahaman peserta terkait langkah-langkah dalam publikasi karya ilmiah juga mengalami peningkatan yang signifikan, dari awal hanya 10% menjadi 90% setelah program dilaksanakan. Data ini mengindikasikan bahwa pelaksanaan program oleh tim telah berhasil secara sangat nyata dalam meningkatkan pemahaman peserta mengenai penulisan dan publikasi karya ilmiah. One of the obligations of a teacher is to make scientific work and publish it through journals or seminars both nationally and internationally. However, there are still many teachers who do not have skills in writing scientific papers, so this service activity aims to provide training in writing scientific papers so that teachers can write well and even publish them in journals. The targets of this community service activity were 25 teachers at SDN Pudak Payung 01 Semarang. Activities are carried out through three stages, namely, observation and coordination with partners, training in writing scientific papers, monitoring and evaluating community service activities to increase the level of understanding of participants, as measured by the team through pretest and posttest instruments. Before the program was run, the participant's level of understanding of writing only reached 20%, but after the program was running, that figure jumped sharply to 95%. Participants' understanding of the steps involved in publishing scientific papers also experienced a significant increase, from only 10% initially to 90% after the program was implemented. This data indicates that the implementation of the program by the team has been very successful in increasing participants' understanding of the writing and publication of scientific papers.

Abstract

High consumption of cooking oil has an impact on the availability of used cooking oil. Used cooking oil can cause pollution if the processing is not sound. So we need an alternative as a solution for handling cooking oil waste. Adsorption using avocado seed adsorbent is the choice because the morphological structure and other characteristics meet the specifications for the adsorption of used cooking oil. This study aimed to determine the acid number, viscosity, density and isothermal adsorption from avocado seeds as an adsorbent in used cooking oil. The method used was by varying the adsorbent doses of 100, 200 and 300 mg    L-1 with contact times of 30, 60, 90, 120 and 150 minutes. Adsorption was carried out at a temperature of 70oC and a stirring speed of 200 rpm. The results obtained for the acid numbers at various adsorbent doses at 150 minutes reached 6.22, 4.98 and 3.12 mg KOH      g-1. Viscosity at different adsorbents reached 54.2, 46.23 and 45.44 mm2 s-1, while the density reached 898.92, 897.17 and 896.55 kg m-3. Langmuir isothermal adsorption obtained R2 value in the equation reached 0.9365 and Freundlich reached 0.9496, so the Freundlich equation model is more recommended for use in the adsorption process because the regression value is close to 1.

Abstract

Rice Bran Oil (RBO) is an oil extracted from rice bran with unsaturated fat content according to World Health Organization (WHO) standards. The enzymatic extraction process of rice bran for oil extraction using cellulase enzymes is considered effective because it is capable of producing oil. Parameters of temperature and incubation time have an influence on the yield of oil produced. So that research is needed regarding the optimum conditions of the enzymatic extraction process including temperature and incubation time on the yield and levels of FFA RBO.Software Design Expert was used in this study to optimize RBO extraction with cellulase using the Response Surface Methodology (RSM) method in the Central Composite Design (CCD) factorial experimental design. The selected independent variables consisted of incubation temperatures, namely 35, 50, and 65 0C and incubation time for 2, 3, and 4 hours. The results show that the RBO yield is 1.7% and the minimum target for FFA levels is 8.4% at a temperature of 51.5 0C with an incubation time of 4 hours. Processing data with Design expert software produces an analysis of ANOVA experimental data. Incubation time has a significant level (p0.05) on RBO yield and incubation temperature has a significant level (p0.05) on RBO FFA.

Abstract

The COVID-19 pandemic has affected the residents of Ngijo, a sub-district in Gunungpati District, Semarang. This community service activity aims to empower the Ngijo Family Welfare Development (PKK), Gunungpati, Semarang, as a solution for making aromatherapy candles from waste orange peel, jasmine flowers, and lemongrass. The methods of community service carried out include preparation, outreach, and evaluation. Preparations included signing a letter of cooperation with partners, making aromatherapy candles through six trials where the aroma smelled very good, and socializing with demonstrations where the team explained the consequences of product failure. Posters were given to residents to strengthen their understanding of this activity. The activity's success was seen in the residents' enthusiasm during the question-and-answer session regarding their understanding of making aromatherapy candles. The empowerment of PKK Ngijo, Gunungpati, and Semarang is successful because this activity is exciting and valuable, especially orange peel, which contains essential oils and has a refreshing aroma.
