Abstract

The purpose of study was to determine kinetic parameters and inhibitory effect of Mg2+ ions on pectinase. Activity test performed at pH 4,5 temperature 55oC for 50' with 10 mm concentrations of each ion 0-10mm. Galacturonic acid content, as product of pectin substrate hydrolysis, was used as basis for determining activity and analyzed by visible spectrophotometry. At concentrations 2 and 4 mm Mg2+ act as an activator, but at concentrations 6, 8, and 10 mM as inhibitors. The value of KM with and without inhibitors is almost same, that is 0.3145% and 0.3105% but value of Vm from both are different, that is 80,645 ?g.ml-1.minute-1 and 62,112 ?g.ml-1.minute-1. The conclusion that type of inhibitory pectinase with Mg2+ is a non-competitive inhibition. The inhibition constant value (Ki) is 26,84.

Abstract

One form of efficiency that can be done by palm oil mill companies so that production targets are achieved is to reduce the number of oil losses or loss of oil in the process of making their products, in this case, are CPO and PKO. This is because the lower the amount of oil losses, the higher the CPO and PKO that will be produced. This study aims to analyze oil losses in the processing of Palm Kernel Oil or PKO with the seven tools method. Data collection techniques in this study used case studies based on literature studies and field studies. Data were analyzed descriptively qualitatively. The conclusion of this research is the analysis of oil losses in the process of making palm kernel oil using check sheets and histograms, the data obtained shows high oil losses in the company PT. XYZ with an average of 8.92% for 4 months, so it is necessary to make improvements that at improving the quality of good palm kernel oil (PKO). Analysis of PKO oil losses at PT. XYZ is also performed using a cause-and-effect diagram. This aims to identify the causes of oil loss which include raw materials, human resources (HR), machinery, and the environment in order to fulfill the oil loss standard designed by the company, which is less than 8.00%, and also prevent high oil losses. which may happen again in the future.

Abstract

Papaya fruit is one source of vegetable protein. This fruit is often cultivated because of its considerable benefits for health. In addition to cultivating papaya plants, farmers also often ripening papaya fruit that has been harvested using ethrel solution. This study aims to describe the effect of The Addition of ethrel solution on the quality of papaya fruit. This research is an experimental study consisting of 5 treatments and 3 replications with a test model that is an organoleptic test to measure the quality of papaya fruit. Research data presented descriptively. The results showed that administration of Ethrel solution affected the quality of papaya fruit with optimal concentration in the treatment of P3 or 0.6% Ethrel per liter of water. Papaya fruit has the best color, texture, and taste in the P3 treatment when compared with the P0, P1, P2, P4, and P5 treatments. The best length of days in the ripening process is five days.

Abstract

Jackfruit skin often considered as by product immediately after the fruit being used or consumed. However, if processed further this jackfruit skin can actually be fermented and has the potential to be a biofuel. Traditionally wastewater from fermented jackfruit skin can produce bioethanol. Bioethanol is ethanol (ethyl alcohol) whose production process uses natural raw materials and biological processes. Considering the current condition, namely fossil fuels in Indonesia are getting scarce, especially motor vehicle fuel, so naturally this bioethanol from fermented jackfruit skin has the opportunity to become a substitute energy. This study aimed to determine the ethanol content of jackfruit skin fermentation. Anaerobic fermentation was done with the addition of 600 ofater and one month incubation. The resulting bioethanol levels were measured with an alcohol meter. The results showed that different levels of salt produced an amount of ethanol which was also different from the fermentation of jackfruit skin. The difference in the amount of ethanol produced is thought to be due to the influence of the growth of lactic acid bacteria.

Abstract

The research was conducted to determine the effect of methanolic extract of manggarsih stem (Parameria laevigata) into the weight of mice’s testicles. The research was carried out by giving methanolic extract of manggarsih stem to Swiss white mice orally, each mice was force-fed 0,5 milliliter / 25–30 g for 35 days with 5 treatments, namely P0 (control with distilled water), P1 (concentration of 5%), P2 (concentration of 10%), P3 (concentration of 15%), P4 (concentration of 20%), and four times repetition. In the day of 36th the mice was dissected to take the testicles, then the testicles weight was measured above analytical balance. Data were analyzed by normality test of Kolmogorov Smirnov, Homogenity test, Analysis of Variance test, and Duncan test. The results showed that parameter of testicles weight was not significant (sig < 0,05). It is concluded that methanolic extract of manggarsih stem can not decrease the mean number of testicles weight.Keywords: manggarsih stem (P. laevigata), methanolic extract, weight of mice’s testicles

Abstract

Abstrak Pandemi COVID–19 memberikan dampak di semua aspek kehidupan salah satunya adalah aspek pendidikan. Seluruh pengajar di semua jenjang pendidikan harus bisa mengajar dalam kondisi tidak bertatap muka secara langsung dengan peserta didik yang diajar. Hal ini tentunya juga akan berpengaruh pada sistem pengajaran saat di kelas yang biasanya dilaksanakan secara offline maka sekarang harus dilaksanakan secara online. Materi ajar yang disampaikan juga harus dimodifikasi agar kompetensi yang didapat oleh peserta didik tetap sama meskipun tidak ada pertemuan face to face. Pembelajaran dengan kelas praktikum juga terkadang harus dilakukan oleh peserta didik sendiri di rumah mereka masing–masing. Oleh sebab itu pengajar harus mampu membuat bahan ajar yang bisa dipahami dengan cukup baik oleh perserta didik. Selain itu, bahan ajar tersebut sebaiknya mendapat tanggapan yang baik juga dari peserta didik. Penelitian ini bertujuan untuk mendeskripsikan respon mahasiswa terhadap modul praktikum berbasis inkuiri terbimbing pada pembelajaran daring mata kuliah teknologi pengolahan limbah. Penelitian ini menggunakan instrumen angket atau kuesioner yang disebar ke 30 mahasiswa untuk mengetahui bagaimana respon mereka terhadap nilai kepraktisan penggunaan modul praktikum daring mata kuliah teknologi pengolahan limbah. Hasil penelitian menunjukkan bahwa pilihan jawaban rata–rata sebesar 90% atau masuk kategori “baik sekali” untuk respon peserta didik terhadap nilai kepraktisan penggunaan modul praktikum daring mata kuliah teknologi pengolahan limbah. Kata kunci : inkuiri terbimbing, modul, praktikum, respon, teknologi pengolahan limbah. Abstract The COVID-19 pandemic has an impact on all aspects of life, one of it is the education aspect. All educators in all levels of education must be able to teach in conditions that are not being able to talk face to face with the students. This will also affect the teaching system when in class which is usually carried out offline so now it must be carried out online. The teaching materials delivered must also be modified so that the competencies gained by students remain the same even though there is no direct meeting. Learning with practical classes also sometimes has to be done by students themselves in their homes. Therefore, educators must be able to make teaching materials that can be understood quite well by students. In addition, these teaching materials should also get a good response from students. This study aims to describe student responses to guided inquiry-based practical modules in online learning for Teknologi Pengolahan Limbah course. This study uses a questionnaire instrument which is distributed to 30 students to find out how they respond to the practical value of using the online practicum module for Teknologi Pengolahan Limbah course. The results showed that the average answer choices were 90% or included in the "very good" category for student responses to the practical value of using the online practical module for Teknologi Pengolahan Limbah course. Keywords : guided inquiry, learning, modules, response, teknologi pengolahan limbah.
