Pengaruh penambahan pati talas (colocasia esculenta) sebagai stabilizer terhadap viskositas dan uji organoleptik yogurt

The aim of this research was to know effect of adding the taro starch (Colocasia esculenta) as a stabilizer on viscosity and organoleptik test. The research method used was a laboratory experiment using a completely randomized desing (CRD), which consists of 4 treatments (P0= without the addition of taro starch, P1= addition of taro starch 0,5%, P2= addition of taro starch 1%, P3= addition of taro starch 1,5%) and 3 replications, then continued by Least Significant Difference (LSD). The result showed that the addition of taro starch as a stabilizer provides highly significant effect (P< 0,01) on the viscosity and texture yogurt. Result showed the highest viscosity values by adding starch 1,5%=8230 cP and the lowest score without the addition of starch is 0%=830 cP. An texture of yogurt on the highest volue with the addition of taro starch 1,5% with a score of 9 and the lowest rate of 0% was 6,8. While adding starch not have the effect of (P>0,05) in color, taste and flavor. The highest score is of a favorite by adding starch 0,5% = 7,4 and the lowest 1% =7,0. Favorit yogurt on the highest score is adding starch 0,5% = 6,47 and the lowest 1,5% =5,53. On fondnes scent highest score by adding starch 0% and 0,5% =7,4 and the lowest value adding starch 1% and 1,5% =7,3. It was concluded that the addition of taro starch as a stabilizer of 1.5% produces yogurt optimum quality in terms of viscosity and texture of yogurt.

Frekuensi penyiraman larutan urin domba terhadap tinggi tanaman, jumlah daun dan produksi segar hidroponik fodder jagung (zea mays)

The purpose of this study was to determine the effect of watering frequency of sheep urine solution on plant height, number of leaves and plant production on corn fodder (Zea mays). The material used in this study was 3.750 corn, sheep urine and water. The method used in this study was a field experiment using a Completely Randomized Design (CRD) consisting of 3 treatments and 5 replications. The research treatment consisted of P1 (watering 1 time /day), P2 (watering 2 times /day) and P3 (watering 3 times /day) with 10% sheep urine solution. The variables observed in this study were plant height, number of leaves and plant production. The analysis used was analysis of variance if there was an effect then continued with the LSD test. Based on the results of the study showed that the frequency of watering the urine solution of sheep gave no significant effect (P> 0.05) on plant height, number of leaves and gave a very significant effect (P <0.01) on plant production. The highest plant height in P2 (36.76 cm), the highest number of leaves in P2 (3.40 strands) and the highest plant production in P2 (374.80 grams). The conclusion of this study is the watering of sheep urine solution 2 times a day giving the best results on plant height, leaf number and fresh hydroponic production of corn fodder (Zea mays).

Hubungan lama masa kering terhadap produksi susu dan puncak laktasi pada sapi perah

Penelitian ini bertujuan untuk mengetahui hubungan lama masa kering dengan produksi susu dan puncak laktasi pada sapi FH. Materi yang digunakan adalah data sekunder dari pencatatan recording 189 ekor sapi FH pada PT. Greenfields Indonesia di Desa Babadan Kecamatan Ngajum Kabupaten Malang. Analisis pengaruh lama masa kering terhadap produksi susu dan puncak laktasi dilakukan dengan menggunakan analisis regresi linier. Hasil analisis regresi menunjukkan bahwa hubungan lama masa kering terhadap produksi susu berpengaruh signifikan (P<0,05) dengan persamaan regresi Y = 28,31 – 1,26 X sedangkan dengan puncak laktasi menunjukkan hubungan yang tidak berpengaruh (P>0,05). Lama masa kering menentukan produksi susu pada sapi perah dengan masa kering yang ideal 55- 60 hari dimana semakin lama masa kering maka produksi susu akan menurun. Kata kunci : masa kering, produksi susu, regresi, sapi FH ABSTRACT The objective of this study was to evaluate the effect of dry period length on milk production and peak milk yield of the Friesian Holstein (FH) dairy cows. Data on milk production from 189 FH cows raised at PT. Greenfields Indonesia were collected and subjected to linier regression analysis. The results showed that dry period length significantly (P<0.05) on affected milk production with regression equation of Y = 28.31 – 1.26 X, but had no significant effect (P.0.05) on peak milk yield. The optimal length of dry period was observed between 55 and 60 days. Milk production decreased with the increasing length of dry period above 55-60 days. Key words : dry period, milk yield, regression, FH cows

Penampilan Produksi Kelinci Fase Pertumbuhan Menggunakan Wafer Ransum Komplit Berbahan Tepung Inti Biji Karet

Rubber seed is agricultural waste can used for alternatif feed. Rubber seed use not enough for make ends meet rabbit, additional feed is needed to complete it to mix the ingredient needed technology, technology that can be used, one of which is wafers. This study aims to determine the performance of the growth phase of rabbit production by using a complete wafer ration with the addition of 0%, 3%, 6% and 9% rubber seed core flour.

Kualitas spermatozoa ayam kampung pada suhu 50C dengan lama simpan yang berbeda

Tujuan penelitian adalah untuk mengetahui kualitas spermatozoa ayam Kampung pada suhu 50C dengan lama simpan yang berbeda. Materi yang digunakan dalam penelitian adalah semen ayam kampung berasal dari 2 ekor ayam Kampung. Penelitian terdiri atas perlakuan lama simpan 0,3,6,9 jam dan diulang 10 kali setiap perlakuan. Data yang diperoleh dalam penelitian dianalisis menggunakan analisis of variance. Metode penelitian yang dilaksanakan menggunakan Rancangan Acak Lengkap (RAL). Hasil penelitian menunjukan bahwa perlakuan memberikan hasil yang berbeda sangat nyata (P<0,01) terhadap motilitas, viabilitas dan abnormalitas spermatozoa pada suhu 5 0C. Standar untuk IB pada motilitas, viabilitas dan abnormalitas (40:80:20). Penurunan setiap perlakuan 0,3,6 dan 9 jam pada motilitas (100±0d, 26,2±2,62c, 17,6±2,45b dan 5,9±0,99a) dan viabilitas (100±0d, 73,4 ± 5,81c, 63,9 ± 5,25b dan 45,9 ± 4,95a). Pada abnormalitas terjadi peningkatan setiap perlakuan dengan nilai 0 ± 0a, 0,3±0,48a ,0,6±0,69a dan 1,2±0,78b. Perlakuan lama simpan 0 jam lebih baik dari 3, 6 dan 9 jam. Berdasarkan hasil penelitian dapat disimpulkan bahwa kualitas semen ayam Kampung yang disimpan pada suhu 5 0C dengan lama simpan yang berbeda yang meliputi motilitas, viabilitas dan abnormalitas spermatozoa yang digunakan untuk IB dan sesuai standar hanya mampu bertahan sampai lama simpan kurang dari 3 jam. Kelayakan untuk IB hanya bertahan pada lama simpan kurang dari 3 jam, oleh karena itu perlu dilakukan penelitian lanjutan untuk mengetahui tepatnya pada jam ke berapa semen layak untuk dilakukan (IB).
