Abstract

Batang tanaman jagung merupakan salah satu limbah hasil pertanian yang mengandung selulosa, hemiselulosa dan lignin. Tujuan dari penelitian ini untuk mengetahui pengaruh konsentrasi  NaOH pada proses ekstraksi selulosa dari batang tanaman jagung terhadap rendemen dan sifat fisik selulosa.Tahap dan metode penelitian meliputi: ekstraksi selulosa batang tanaman jagung melalui proses delignifikasi, pencucian, blanching, pengeringan dan pembuatan serbuk selulosa. Percobaan menggunakan waktu ekstraksi selama 60 menit dengan konsentrasi NaOH (K) dengan 5 tarafperlakuan yaitu K1= 10%, K2= 15%, K3= 20%, K4= 25% dan K5= 30%. Masing-masing perlakuan diulang tiga kali dan masing-masing dianalisis dengan dua ulangan. Sehingga diperoleh unit percobaan  3x5x2 = 30 unit percobaan. Analisis produk selulosa secara fisik meliputi pengukuranrendemen, pH, Water Holding Capacity (WHC) dan Oil Holding Capacity (OHC). Hasil penelitian menunjukan bahwa penggunaan NaOH konsentrasi 25% pada proses ekstraksi selulosa batang jagung menghasilkan rendemen tertinggi sebesar 35,61%; nilai pH rata-rata sebesar 8,66. Kemampuan mengikat air (WHC) tertinggi sebesar 8,21 g/g dan kemampuan mengikat minyak (OHC) sebesar 9,76g/g. Keywords: Selulosa, batang tanaman jagung, Ekstraksi, Natrium Hidroksida

Abstract

Fluctuations in blood glucose levels in Diabetes Mellituspatients to be the main cause of developing complications, due to the formation of free radicals which can lead to oxidative stress. Many studies have been done, but it is still rare that utilize food that can be consumed daily as a source of vegetable-based therapy. Vitaral mix is the formula of food sourced watercress and black rice bran. Watercress contains vary nutrients vitamins B1, B2, C, E, provitamin A, folic acid, protein, glucosinolates, minerals iodine, iron, calcium, and phosphorus. Black rice bran contains anthocyanins were shown to have strong antioxidant activity. This study aimed to analyze the effect of vitaral mix diet to changes in the levels of HDL and LDL cholesterol, which treated on animal models. The results showed that the levels of HDL in the control group is 44.7 ± 2.19 mg / dl during the study, as well as LDL (59.6 ± 2.89 mg / dl). HDL levels in the group of diabetic rats increased 3.4 ± 2.99 mg / dL, while elevated LDL levels is 19.6 ± 11.33 mg / dl. HDL levels of diabetic rats with vitaral mix diet increased significantly during the study amounted to 53.9 ± 3.59 mg / dl, but LDL levels decrease with 9.9 ± 5.72 mg / dl.Keywords:vitaral mix, HDL, LDL

Abstract

The regency of Jepara in Central Java Province has a special food called “oven peanut”, it is peanut which is roasted by using beach sand. One of the significant problems of the producer of this food is the production process which still be done in traditional method. This research attempts to overcome this problem by introduce the usage of machine to roast this food. The specification of this machine are made by the stainless steel, move in rotation with the motor of 0,25 PK equivalent with the electricity of 180 watt, and the heater is a LPG two burner stove, the temperature inside the machine can be controlled by the thermostat which has been installed to this machine. This research modifies the common grain roasted machine, in order to be fit to process the “oven peanut”, several modifications are applied. First to prevent the peanut breaks because of collision with the inner side of machine, the speed of machine rotation is decelerated; second to prevent the beach sand seep from the gap of material intake/exit valve, the front part of the machine is lifted up with lever. Several experiments in temperature setting then done to produce the best product, the result is the temperature of 60 Celsius degree produce the best product with the white color appearance and a good taste of peanut.Keywords: oven peanut, grain machine, modification

Abstract

This research is a quasi-experimental research and research design used is pretest post-test control group design. This study aims to determinethe outcomes of learning physics by learners who taught conventionally, to determine the outcomes of learning physics by learners who the taught cooperative learning model type pair checks and to determine significant difference between the result of physics learning by learners who taught in a conventional and are taught by cooperative learning model type pair checks. The sample of this study were 48 students, consist of 24 students in the experimental class and 24 students in the control class. The average value of the experimental class students is 84.58. For the average value of the control, class students are 80.33.The results of the analysis carried out by using the t-test obtained t value of 4.2 with Sig. (2-tailed) of 0,000 with a significant level of 5%. Therefore the value of Sig. (2-tailed) <0.05, it can be said that there are significant differences in physics learning outcomes between the control class and the experimental class that use the cooperative learning model type pair checks.

Through archival work experiences is expected to connect between universities, especially Open University and field employment.The demands of the field employment are not only for the theory but also the students ‘outstanding characters;such as honesty, discipline, work ethic, competitiveness, and  loyalty. Based on the observations on archival work experiences, the instruments still emphasize only the knowledge aspect which is less able to measure anddevelop the student’ characterist ics. This research was conducted at UPBJJ-UT Semarang by taking samples ofthree regencies / cities; such as Semarang, Batang, and Pati. The research uses descriptive research based onCIPP evaluation model. The CIPP model has a special component in the evaluation of context, input, process,and product. The result shows that the implementation of archival work experiences had been done well.Lecturers and advisors have built character education to students either directly or indirectly. In contrast, it hadnot been clear character assessment. Therefore, it is necessary to plan the student’ character assessmentinstrument clearly and precisely which is integrated in final assessment. The characters building that can be builtin archival work experiences are discipline, honest, creative, curiosity, passion, hard work, friendly / communicative, responsibility, and environment awareness. In conclusion, it is expected that there is an instrument of student character education assessment in archival work experiences. Keywords: character education, archival work experiences, CIPP model
