The objective of this study was to evaluate the effect of molasses as carbohydrate source and inoculums of lactic acid bacteria (LAB) incubated from PO cattle's rumen fluid on the quality of Napier grass (pennisetum purpureum) silages. The research was conducted at Gemawang village Jambu District Semarang Regency. Feed analysis was carried out in Laboratory Biochemical Nutrition, Animal Feed Science, Animal Science Faculty, Gadjah Mada University. This study was assigned into Completely Randomized Design with 4 treatments and 3 replicated.The treatments were addition of molasses and LAB level into the Napier grass; 0, 1, 3 and 5% (w/w) and incubated for 30 days Data were analyzed using analysis of variance (ANOVA) and the significant effect was tested by Duncan ,s Multiple Range Test. The results showed that the addition of 1 -5% molases significantly affected (P<0,05) lactic acid content, pH, and NH3 concentration. Increasing level of molases significantly (P<0,05) increased lactic acid content, decreased pH and NH3 concentration of Napier grass silage. However, among the treatment groups of 1, 3 and 5 % of molases was not significant (P<0,05) different on the lactic acid content, pH and NH3 concentration. Dry matter and organic matter content of Napier grass silage were not significantly (P<0,05) affected by treatments . Peternak pada umumnya sering mengalami permasalahan kekurangan atau sampai kesulitan mendapatkan hijauan makanan ternak segar sebagai pakan ternak. Salah satu cara penanggulangan yang dilakukan peternak adalah dengan memberikan pakan seadanya yang diperoleh dengan mudah di sekitarnya tampa melihat baik buruk kandungan nutrisinya. Pemberian pakan ternak seadanya sangat mempengaruhi prduktivitas ternak seperti pertumbuhan , penambahan berat badan terlambat, rendah tingkat birahi dan terganggunya siklus reproduksi serta turunnya produksi susu (Parakkasi, 1999) Pada musim hujan, dijumpai hijauan makanan ternak yang berlimpah sebaliknya pada musim panas kekurangan hijauanCorresponding author: ismail_jasin@ymail.com makanan ternak, sehingga upaya pengawetan hijauan segar yang disebut silase diharapkan dapat menjadi salah satu solusi untuk mengatasi permasalahan kekurangan hijauan segar pada musim kesulitan pakan. Selain itu, pembuatan silase dimaksud untuk mempertahankan kualitas atau bahkan meningkatkan kualitas hijauan makanan ternak. Hal ini sangat penting karena produktivitas ternak merupakan fungsi dari ketersediaan pakan dan kualitas (Leng, 1991) Kurangnya kadar gula terlarut dalam proses ensilase menyebabkan bakteri asam laktat kekurangan asupan energy untuk melakukan aktivitasnya, sehingga bakteri asam laktat menggunakan zat-zat lain yang terkandung dalam hijauan yang memungkinkan digunakan sebagai sumber energy dan menyebabkan berkurangnya nilai nutrisi hijauan tersebut. Untuk menjamin keberhasilan

The effect of giving cassava meal and inoculums of lactic acid bacteria (LAB) incubated from PO cattles rumen fluid on the quality of napier grass (Pennisetum purpureum) have been done at Ujung ujung village Pabelan, the Semarang district. Analysis of nutritional value was carried out at the Biochemical Nutrition and Food laboratory, Animal Feed Science Faculty, Gadjah Mada University. The research used complete random design consisted of 4 kinds of treatment and 3 replications. There were; T0 = silage control, T1 = silage with cassava meal 1% and inoculum of lactic bacteria from PO cattles rumen fluid 106 cfu/g forages, T2 = silage with cassava meal 3% and inoculum of lactic bacteria from PO cattles fluid 106 cfu/g forage, T3 = silage with cassava meal 5% and inoculum of lactic bacteria from PO cattles fluid 106 cfu/g forages. The study parameters were lactic acid, pH, dry matter, crude protein, and crude fiber. To verify the effect of treatments, data analysis was continued with the Duncan Test. The results showed that the addition of cassava flour had a significant effect on LAB, pH, NH3 the crude protein and crude fiber. While on dry matter there was not a significant effect. The best treatment was napier grass silage with 5% of cassava meal.

The objective of this study was to evaluate the effect of cassava meal as carbohydrate source and inoculums of lactic acid bacteria incubated from PO cattle's rumen liquid on the quality of Napier grass (pennisetum purpureum) silages. The research was conducted at Ujung-ujung village Pabelan District Semarang Regency. Feed analysis was carried out in of Biochemical Nutrition, Animal Feed Science, Animal Science Faculty, Gadjah Mada University. This study was assigned into Completely Randomized Design with 4 treatments and 3 replicated. The treatments were addition of cassava meal and inoculums of lactic acid bacteria level into the Napier grass; 0, 1, 3 and 5% (w/w) and incubated for 30 days. Data were analyzed using analysis of variance (ANOVA) and the significant effect was tested by Duncans Multiple Range Test. The results showed that the addition of 1 -5% cassava meal significantly affected (P<0,05) lactic acid content, pH, and NH3 concentration. Should be revised However, among the treatment groups of 1, 3 and 5 % of cassava meal was not significantly (P<0,05) different on the lactic acid content, pH and NH3 concentration.

The objective of this study was to study the effect of isolated lactic acid bacteria (BAL) addition on lactic acid production and pH of tofu waste and for improving the expired tofu waste industry. Inoculum from liquid media as starter was applied anaerobically for 0%; 5% and 10% and different incubation time were 0; 3; 6; 12; 24; 48 and 72 hours. Variabel measure in this study were lactic acid production and pH.The different level addition level of inoculum percentage applied in tofu waste improve expired date of tofu waste industry, and incubation time very significantly increase lactic acid production (P<0.01). As a conclusion of this study showed that 10% of inoculum and 24 hours incubation perform an optimum of tofu waste industry fermentation.
