This research aims to determine the rate of manure bokashi addition on growth and production in the first harvest of King grass (Pennisetum purpureophoides). The observed parameters consisted of plant height, number of tillers, fresh weight production, dry weight production, dry matter production. This research method used non factorial Randomized Block Design (RBD), consisting of 6 (six) treatments with 4 (four) replications. As for the treatment performed is P0: Not using manure bokashi (control). P1: 50g / Polybag. P2: 75g / Polybag. P3: 100g / Polybag. P4: 125g / Polybag. and P5: 150g / Polybag. From 6 treatment levels and 4 replications we got 24 experimental units with 3 sample plants each, so the total sample used were 72 experimental units. To know the effect of treatment, the data obtained were analyzed by analysis of variance and real honest difference (RHD) advanced test. Based on the result of research that the level of addition of manure bokashi significantly affect on plant height, number of tillers, fresh weight production, dry weight production and dry material production. The additional level of cow dung bokhasi of 30 tons/ha (P5) was able to give the best effect on all observed variables.

Penelitian ini bertujuan untuk mengetahui level ekstrak buah nanas (Ananas comosus L. Merr) dan lama perendaman terhadap kualitas daging itik afkir. Parameter yang diamati adalah pengaruh penambahan ekstrak buah nanas yang mengandung bromelin, lama perendaman dan interaksi antara kedua faktor terhadap susut masak, pH, kadar protein, kadar lemak dan kadar air daging itik afkir. Itik yang digunakan adalah 18 ekor itik Tegal umur 84 minggu. Sampel yang digunakan untuk uji susut masak, pH, kadar air,kadar lemak, dan kadar air adalah daging paha. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) Pola Faktorial 3 × 3, dengan faktor pertama penambahan ekstrak buah nanas (0%, 10%, 20%) dan faktor kedua lama perendaman (15, 30, 45 menit). Terdapat interaksi antara penambahan ekstrak buah nanas dan lama perendaman (P<0,01) pada kadar lemak dan (P<0,05) pada kadar protein. Penambahan ekstrak buah nanas dan lama perendaman dapat meningkatkan kadar protein daging itik afkir dan menurunkan kadar lemak daging itik afkir. Penambahan ekstrak buah nanas 10% dan waktu perendaman 30 menit menghasilkan kualitas daging itik yang terbaik karena mampu menurunkan kadar lemak dan meningkatkan kadar protein.

he purpose of this study was to see the success rate of Artificial Insemination on beef cattle  in Purwodadi district, Musi Rawas Regency. The parameters observed is Service per Conception (S/C), Conception Rate (CR), Non Raturn Rate (NRR) and Calving Interval (CI).  Survey method isused  in this study by taking all area of Purwodadi district as the observed area because of its livestock population then analysed by using Slovin Formula to obtain 93 samples. The results of this study concluded that the Conseption Rate (C/R) in Purwodadi District was very good because it was obtained 70.96%. Figures for   S/C in Purwodadi sub-district showed an average of 1.4. As for the NRR value in Purwodadi Subdistrict, NRR(0-30) obtained a percentage of 70.96%. NRR(31-60) obtained 93.54% and NRR(61-90) obtained 100%. The value of the Calving Interval (CI) is very good, reaching an average of 14.7 or 14 months 7 days.Keywords: Artificial insemination, Purwodadi district, Beef Cattle, Success Rates

This study aimed to determine and examine the effect of the addition of soursop leaves flour in fermented rice straw-based rations on the digestibility value of dry and organic matter conducted by In Vitro. The design used was a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The treatments tested consisted of: P0 = basal ration, P1 = P0 + Soursop leaves flour 1%, P2 = P0 + Soursop leavesflour 2%, P3 = P0 + Soursopleaves flour 3%. Basal ration consisted of 45% fermented rice straw, Mini Elephant Grass 30%, bran 10%, coconut cake 10%, milled corn 4%, and Premix 1%. Variables observed were dry matter digestibility (DMD) and organic matter digestibility (OMD). The data obtained were analyzed using Variance Analysis followed by Duncan's Multiple Range Test (DMRT). The results of the study of the addition of soursop leaves flour in fermented rice straw-based rations had a significant effect (P<0.05) on DMD and OMD. The highest DMD and OMD values were shown by the treatment of P3 (3% Soursop leaves flour) respectively which were 60.43% and 61.76%. The conclusion of this study is the digestibility value of dry matter and organic matter increases with the higher addition of soursop leaves flour in the ration. The addition of soursop leaves flour in fermented rice straw-based rations did not have a negative impact on the digestibility of dry matter and organic matter and could be added up to 3% in the ration.

Penelitian ini bertujuan untuk mengetahui nilai pH, VFA, dan NH3 ransum yang diberi penambahan tepung daun sirsak secara In Vitro. Penelitian dilakukan melalui beberapa tahapan yaitu persiapan ransum perlakuan yang dilaksanakan di Laboratorium Fakultas Pertanian dan  pelaksanaan pengukuran pH, VFA, dan NH3 secara In Vitro dilakukan di Laboratorium Nutrisi Ternak Perah IPB.  Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Perlakuan terdiri : T0 = Ransum basal, T1 = Ransum basal + Tepung daun sirsak 1%, T2 = Ransum basal + Tepung daun sirsak 2%, T3 = Ransum basal + Tepung daun sirsak 3%. Peubah yang diamati pH, VFA dan NH3. Data yang diperoleh dianalisis menggunakan analisis ragam dan uji lanjut  jarak berganda Duncan. Hasil penelitian menunjukkan bahwa perlakuan penambahan tepung daun sirsak dalam ransum secara In Vitro berpengaruh nyata (P<0,05) terhadap nilai pH, VFA, dan NH3. Nilai pH tertinggi ditunjukkan T0 (6,95) dan terendah T3 (6,73), nilai VFA tertinggi T3 (130,95 mM) dan terendah T0 (73 mM), serta nilai NH3 tertinggi ditunjukkan T3 (10,90 mM) dan terendah T0 (8,73). Kesimpulan dari penelitian ini adalah bahwa penambahan tepung daun sirsak dalam ransum hingga 3% signifikan menurunkan nilai pH, meningkatkan nilai VFA dan NH3
