Abstract

Susu kelapa mengandung lemak dan protein serta kadar air yang tinggi sehingga menyebabkan produk ini mudah rusak. Untuk mendapatkan susu kelapa yang awet atau tidak mudah rusak, maka perlu ditambahkan bahan pengawet alami seperti vitamin E. Penelitian ini bertujuan untuk mengetahui ada atau tidaknya pengaruh penambahan vitamin E terhadap bilangan peroksida , pH, dan kadar protein dengan variasi waktu. Perubahan kualitas yang diamati berupa bilangan peroksida ditentukan dengan cara titrasi, pH ditentukan dengan pHmeter dan, kadar protein ditentukan dengan metode kjedhal dengan variasi waktu 0 (kontrol), 4, 8, dan 12 hari pada suhu 30C. Kualitas susu kelapa yang ditambah dengan vitamin E 100 IU dengan variasiwaktu 0 (kontrol), 4, 8, dan 12 hari masing-masing adalah: bilangan peroksida 0,3740; 0,4760; 0,6120; 0,6800 meq/kg , pH 6,1700; 5,9066; 4,7167 dan 4,0333, kadar protein 2,6657%; 2,3492%; 1,7163%; 0,8630%. Sedangkan kualitas susu kelapa tanpa penambahan vitamin E dengan variasiwaktu 0 (kontrol), 4, 8, dan 12 hari masing-masing adalah: bilangan peroksida 0,3400; 0,5440; 0,8840; 1,1560meq/kg, pH 6,1767; 4,6266; 3,1333; 2,2166, dan kadar protein 2,6561%; 1,5917%; 0,9876%; 0,4123%.

Abstract

  Traditional medicine from drug crop has more than a pharmacological effect so that its use should be acurate and correct. The mistake in traditional medicine usage and or drug crop can be dangerous for health. Therefore, it is required a complete scientific information to avoid it. It had been done the research of anti-bacteria activity test from crude extract of ethyl acetate and ethanol from skin and seed of Pulasan to bacterium Staphylococcus aureus and Escherichia coli with dilution method to determine Minimum Inhibitory Concentration (MIC) and Minimum Bakterisidal Concentration (MBC). The biggest MIC and MBC was respectively obtained from ethyl acetate extract that was 0,76 mg/ml, and ethanol extract that was 156,13 mg/ml. In general, skin and fruit seed extract of pulasan (Nephelium mutabile) has bigger resistance ones to bacterium Staphylococcus aureus compared to Escherichia coli.

Abstract

Along with the increasing need for non-perishable foodstuffs, hazardous chemical food additives (FA) such as borax and formalin are widely used in the food industry, such as in making wet noodles, meatballs, rice cake, tofu, and others. This dangerous chemical FA is usually used as a food preservative, even though these chemicals are poisonous and dangerous to human health so that their use is strictly prohibited by the government. In order to anticipate the wider negative impact of the use of hazardous chemical FA added to foodstuffs, it is necessary to carry out counseling and socialization activities regarding healthy food free of hazardous chemical FA by mastering the technology for identifying food additives and handling them. This activity uses a method of mentoring the community learning process in the form of counseling and training. The target of the socialization activity was the majelis taklim of Babussalam Mosque, Tampan District, Pekanbaru City. The overall implementation of the activity exceeded the desired target because 96% of the participants understood food additives, 83.3% understood tips on recovering healthy and hazardous FA-free food, and 84% were interested in making hazardous chemical FA detection tools.

Abstract

Abstract Modeling and laboratory simulation can help overcome of cost obstacle, time, safety and other constraints in laboratory experiments. Many skills also had the opportunity to be fostered and promoted, especially in connection with the construction of thinking skills. However, the implementation of this program required an evaluation, in order to decided whether the program will be continuing or not, in addition its needed to found the focused of on overall quality of learning in order to make a recommendation in the decision making. This research was conducted by the mixed-method approached with triangulation design, in order to evaluate the effectiveness, problems or any obstacles of the implementation of the program. The population in this study was the third semester of pre-service chemistry students at UIN Syarif Kasim Sultan Riau, which was supported by lecturers, assistant laboratory and staf. The sample selection was done using random sampling techniques. Program evaluation in this study was conducted by the CIPP model (Context, Input, Process, Product). The results showed that the program was running quite effective when viewed from the overall average grades. The evaluation about context, inputs, processes and products had the good and very good score, in which the evaluation score of context and input, get the better score than process and product evaluation. This study recommends to be a continuing improvement program of modeling and simulation laboratories, both as an exercise before the experiments or replace the real experiments. Keywords: modeling; simulation lab; chemistry experiment Abstrak Pemodelan dan simulasi laboratorium dapat membantu mengatasi kendala biaya, waktu, alasan keselamatan dan kendala lainnya dalam praktikum di laboratorium kimia. Beragam kemampuan lain juga berkesempatan untuk ditumbuh-kembangkan terutama dalam kaitannya dengan konstruksi berfikir. Meskipun demikian, implementasi pelaksanaan program ini memerlukan evaluasi, guna memutuskan apakah program ini layak dilanjutkan ataukah tidak, selain karena diperlukannya penemuan terhadap fokus peningkatan kualitas pembelajaran secara menyeluruh guna menghasilkan rekomendasi dalam menentukan keputusan. Penelitian ini dilakukan dengan menggunakan pendekatan mixed-method desain triangulasi, guna mengevaluasi sebab-sebab efektifitas, kendala ataupun kegagalan pelaksanaan program. Populasi dalam penelitian ini adalah mahasiswa semester III jurusan Pendidikan Kimia UIN Sultan Syarif Kasim Riau, yang didukung oleh dosen, asisten laboratorium dan laboran dan pemilihan sampel dilakukan menggunakan teknik random sampling. Evaluasi program dalam penelitian ini dilakukan menggunakan model CIPP (Context, Input, Process, Product). Hasil penelitian menunjukkan bahwa program ini berjalan cukup efektif jika dilihat dari rata-rata keseluruhan nilai, mulai dari context, input, proses dan produk yang berada pada skor baik dan sangat baik, di mana skor evaluasi context dan input, lebih baik dibanding proses dan produk. Penelitian ini memberikan rekomendasi untuk terus meningkatkan penggunaan pemodelan dan simulasi laboratorium kimia, baik sebagai latihan sebelum praktikum maupun menggantikan praktikum yang sesungguhnya.
