The study aims to examine the improvement in the quality of fermented wheat pollard added with vitamins and minerals seen from total bacteria, gram positive and negative. The research material consisted of wheat pollard, fermented cabbage waste, aquades, salt, molasses, vitamins minerals there are CoSO4 , KAI(SO4)2, Na2SeO3, H3BO3, Na2MaO4 , vitamin C, vitamin E, vitamin B Kompleks, CO(NH2)2, NaCl, MgSO4, MnSO4, ZnSO4, CaCl2, FeSO4, CuSO4, MSG. The research method was started by smoothing cabbage waste by adding 8% salt and 6.7% molasses by the weight of cabbage, then fermented for 6 days. Fermented cabbage waste is then mixed with wheat pollard which has been previously heated at 121 ° C for 15 minutes and mixed with vitamins and minerals and then fermented for 4 days. Research design uses a Completely Randomized Design (CRD) of directional patterns with 5 treatments and 3 replications. The treatment given is the difference in the addition of vitamins and minerals by 0% (T0), 2,5% (T1), 5% (T2) and 7,5% (T3). The results showed that total bacteria was significantly different (P< 0.05) in all treatments, gram positive bacteria were not significantly different (P> 0.05) in all treatments and gram negative bacteria were not significantly different (P> 0.05) in all treatments. The conclusion of the study was that the addition of vitamins and minerals to fermented wheat pollard reduced total bacteria, gram-positive and gram-negative bacteria from the microbial population

The vinegar production needs two steps, the sugar changing to alcohol by yeast and then alcohol changing to vinegar by acetic acid bacteria. The vinegar could be produce by slow methods. The purposed of this study were to determine the influence of yeast and sugar using against the quality of fermentation result in first step (anaerobic), analyzing the influence of fermentation time against the vinegar quality based on SNI 01-3711-1995, and study the influence of fermentation time against the acetic acid content in second step (aerobic) with slow methods. This research used completely randomized design, the adding sugar (3 level) and yeast (3 level) as treatment. Each treatment was repeated three times. While the observation of vinegar quality used experiment research without the difference of treatment and repetition, used single error design. Result of research showed that vinegar quality have been suitable with SNI 01-3711-1995 about vinegar, include form, smell, acetic acid content, formic acid and oxalic acid. If the fermentation time be longer, the acetic acid content be lower in aerobic fermentation with slow methods, it was showed by the exponential regression formula ?= 20,695e-0,088x.

Metode penelitian menggunakan percobaan lapang dengan rancangan acak lengkap dengan tiga perlakuan pemberian MO sebesar 0 kg/ekor/hari (P1); 0,05 kg/ekor/hari (P2) dan 0,1 kg/ekor/hari (P3). Analsis data menggunakan one way analysis of variance. Masing-masing perlakuan terdiri atas empat ekor dengan tiga periode pengamatan sebagai ulangan, yaitu periode pertama dan ketiga tanpa MO, dan periode kedua diberikan MO pada P2 dan P3. Hasil penelitian menunjukan bahwa volume dan pH semen perlakuan P1, P2 dan P3 tidak berbeda semua periode pengamatan. Motilitas massa spermatozoa P2 dan P3 periode kedua dan ketiga menunjukan nilai +++ berbeda nyata (P<0,05) dibandingkan dengan P1 (++); motilitas individu  perlakuan P1 menunjukkan nilai terendah 60,56±2,94 % (P<0,05) dibandingkan P2 dan P3 pada periode kedua dan ketiga (75,50±2,29 dan 72,50±2,34%). Konsentrasi spermatozoa P2 dan P3 periode kedua dan ketiga menunjukkan rata-rata  >1.350 juta/ml berbeda nyata (P<0,05) daripada P1 (876±152juta/ml), sedangkan total spermatozoa motil menunjukkan nilai tertinggi 5.647±829 juta/ml pada P3 periode kedua.Viabilitas spermatozoa P2 dan P3 menunjukkan nilai >88-89 % beda nyata (P<0,05) daripada P1 (<84 %) pada periode kedua dan ketiga, sedangkan nilai abnormalitas spermatozoa yang terbaik adalah P2 sebesar 4,30% pada periode kedua dan P3 sebesar 5,33% pada periode ketiga.

The research method used was a field experiment with a completely randomized design with three treatments giving MO of 0 kg/head/day (P1); 0.05 kg/head/day (P2) and 0.1 kg/head/day (P3). Each treatment consisted of four heads with three periods of observation as replications, namely the first and third periods without MO, and the second period was given MO on P2 and P3. Data analysis used a one-way analysis of variance. The results showed that the volume and pH of semen treated P1, P2, and P3 didn’t different in all observation periods. The second and third period spermatozoa mass motility of P2 and P3 showed that the value of +++ was significantly different (P<0.05) compared to P1 (++); Individual motility of P1 treatment showed the lowest value 60,56±2,94 % (P<0.05) compared to P2 and P3 in the second and third periods (75,50±2,29 and 72,50±2,34%). The second and third periods of P2 and P3 spermatozoa concentrations showed an average of >1,350 million/cc significantly different (P<0.05) than P1 (876±152 million/cc), while the total motile spermatozoa showed the highest value of 5,647±829 million/cc in the second period P3. The spermatozoa viability of P2 and P3 showed values >88-89% significantly different (P<0.05) than P1 (<84%) in the second and third periods, while the best spermatozoa abnormalities were P2 at 4.30% in the second period and P3 at 5.33% in the third period. It was concluded that the giving of MO leaf powder at a dose of 0,1 kg/head/day could improve the quantity and quality of semen (viability and total motile spermatozoa) of Ongole Crossbreed bulls.

Soybean (Glycine max (L) Merr) is needed as an alternative diversification in order to increase protein consumption. Soybean can be processed into variety of foods and drinks. The most popular drink from soybean is soya milk which is made from soybean extract yielded from the addition of water. The amount of water added determine the quality of soya milk due to its effect on the chemical and physical properties of soya milk. This research was intended to find out the proper ratio of soybean and water in the processing of soya milk to yield the best quality. A completely randomized design was used with eight treatments of soybean and water ratio as follows, ratio of 1 : 6, ratio of 1 : 8, ratio of 1 : 10, ratio of 1 : 12, ratio of 1 : 14, ratio of 1 : 16, ratio of 1 : 18 and ratio of 1 : 20. Result showed the soybean and water ratio 1 : 10 in the processing of soya milk yielded milk having good quality according to its chemical with protein content of 2.53%, fat of 1.20%, sugar total of 1.60%, pH of 7.1, and organoleptic characteristies of both somewhat sweet taste and viscous texture.
