Penelitian ini bertujuan untuk mengetahui antibakteri masker kefir susu kambing pada Staphylococcus epidermidis dan menghitung jumlah koloni Bakteri Asam Laktat (BAL) dan khamir. Uji antibakteri dilakukan dengan metode difusi sumuran. Antibakteri masker kefir ditunjukkan dengan adanya zona hambat yang terbentuk di sekitar sumuran. Spread plating dilakukan untuk menghitung koloni bakteri asam laktat dan khamir. Medium MRSA dan PDA diinkubasi pada suhu 37ºC selama 2-3 x 24 jam. Jumlah koloni yang tumbuh dihitung menggunakan metode Standard Plate Count dengan jumlah koloni 30-300, dan dinyatakan dalam satuan CFU/g. Hasil penelitian menunjukkan bahwa masker kefir mempunyai sifat bakteriostatik. Kemampuan antibakteri masker kefir susu kambing pada Staphylococcus epidermidis disebabkan karena di dalam supernatan masker kefir terdapat senyawa antibakteri. Hal ini ditandai dengan terbentuknya zona irradikal. Rerata koloni BAL pada masker kefir susu kambing A dan B adalah 1,5×109 dan 1,2×1010 CFU/g. Rerata jumlah koloni khamir pada masker kefir susu kambing A dan B adalah 2,1×1010 dan >3,0×1010 (3,9×1010) CFU/g.ANTIBACTERIAL OF GOAT’S MILK KEFIR MASK ON Staphylococcus epidermidis IN VITROThis study was aimed at determining the antibacterial goat’s milk kefir mask on Staphylococcus epidermidis and the number of Lactic Acid Bacteria (BAL) and the number of yeast colonies. The antibacterial test was carried out using the diffusion method of the wells. The antibacterial activity in the kefir mask is shown by the presence of inhibitory zones that form around the well. Spread plating was done to calculate the colonies of lactic and yeast acid bacteria. MRSA and PDA medium were incubated at 37ºC for 2-3 x 24 hours. The number of growing colonies is calculated using the Standard Plate Count method with the number of colonies of 30-300 and expressed in units of CFU/g. The results showed that kefir masks had bacteriostatic properties. The antibacterial ability of goat’s milk kefir mask was since the kefir supernatant contained antibacterial compounds. This is indicated by the formation of an nonradical zone. The mean of BAL colonies in goat milk masks A and B was 1.5 × 109 and 1.2 × 1010 CFU/g. The average number of yeast colonies in Goat milk masks A and B was 2.1 × 1010 and> 3.0 × 1010 (3.9 × 1010) CFU/g.

Candida albicans cause opportunistic infection of the oral cavity. Probiotic has health benefits, produces organic acids as anti-C. albicans. The aim of this research was to determine the antifungal activity of commercial fermented milk products against Candida and viability of bacteria in commercial fermented milk products. The antifungal activity was determined using well diffusion method. Viability of lactic acid bacteria was done by plate count method. The results show that commercial fermented milk productshas an activity of anti-C.albicans were shown by irradical zone formed around well containing fermented dairy products. Viability of lactic acid bacteria 107-1010 CFU/mL.

Patties analogs are products made from vegetable protein that is not from meat but resembles the nature of meat. Patties analog has several features, including being made or formulated so that the nutritional value is higher than the original meat. The purpose of the study was to determine the process of making patties analog, to determine the formulation of mung bean flour, kidney bean flour and peanut flour combined with wheat flour, to produce the best patties analog. Moreover, it is to determine the yield’s physical, chemical, and sensory of patties analog produced. The main ingredients used are kidney bean flour, mung bean flour, and peanut flour, as well as additional ingredients such as oyster mushrooms, high protein wheat flour, and seasonings with the same percentage. Based on the analysis of the water content of the three samples, the highest value is the water content of kidney bean flour patties (25.88%). The highest ash content is indicated by mung bean flour patties which is equal to 0.08%. The highest fat content obtained by peanut patties with a value of 0.4% and the highest WHC is found in peanut patties that is 2.9867%. Meanwhile, based on the organoleptic test, the most preferred patty analog by panelists is a patty made of mung bean flour.

Terpentin mengandung α-pinene yang merupakan komponen utamanya yaitu sekitar 75-85% dan sisanya terdiri dari β-pinene (2-3%), champhene (4-15%), limonene (5-15%). Alpha-Pinene sebagai komponen terbesar dalam minyak terpentin dapat ditingkatkan nilai jualnya dengan reaksi hidrasi untuk menghasilkan α-terpineol. Tujuan dari penelitian ini untuk mengetahui pengaruh suhu dan waktu reaksi terhadap konversi α-pinene dan selektifitas α-terpineol pada sintesis α-terpineol dari terpentin dengan menggunakan katalis asam trikhloroasetat. Variabel yang diteliti adalah pada suhu 55oC; 65oC; 75oC dan waktu reaksi 30 menit; 60 menit; 120 menit dan 240 menit. Reaksi dilakukan dalam labu leher tiga yang dilengkapi dengan pemanas, termometer, dan magnetic stirrer. Sintesis α-terpineol dilakukan dengan mereaksikan 0,055 mol minyak terpentin, 0,55 mol akuades, dan 0,32 mol katalis asam trikhloroasetat dengan kecepatan pengadukan sekitar 385 rpm. Analisis hasil sintesis menggunakan Gas Chromatography (GC) untuk mengetahui konsentrasi α-pinene dan α-terpineol yang diperoleh, dan Gas Chromatography-Mass Spectroscophy (GC-MS) untuk mengetahui senyawa yang terkandung dalam sampel. Kondisi optimum diperoleh pada suhu reaksi 65oC dan waktu reaksi 60 menit dengan konversi α-pinene yang diperoleh sebesar 96,293% dan selektifitas α-terpineol 34,429%.
