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.

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). Keywords: sheep urine, corn fodder, plant height, number of leaves and plant production

Tujuan dari penelitian untuk mengetahui pengaruh penambahan stabilizer pati talas lokal (Colocasia esculenta) terhadap sineresis dan sensori yogurt pada masa inkubasi 18 jam suhu ruang.Materi yang digunakan dalam penelitian ini adalah susu sapi segar, pati talas, susu skim, dan starter (Lactobacillus bulgaricus,Streptococcus thermophillus dan Lactobacillus acidhopilus). Metode penelitian yang digunakan adalah percobaan Laboratorium  dengan menggunakan Rancangan Acak Lengkap (RAL). Perlakuan penelitian yakni penambahan pati talas, yaitu: P0 (0%), P1 (0,50%), P2 (1%), P3 (1,50%), P4 (2%) masing-masing perlakuan diulang sebanyak 4 kali. Data yang diperoleh dianalisis dengan analisis ragam, apabila terdapat perbedaan maka dilanjutkan dengan uji duncan. Variabel yang diamati meliputi: Sineresis dan Sensori yogurt. Hasil penelitian menunjukan bahwa penambahan level pati talas lokal (Colocasia esculenta) yang berbeda sebagai stabilizer memberikan pengaruh perbedaan yang sangat nyata (P<0,01) terhadap sineresis dan tekstur yogurt. Nilai Sineresis tertinggi dengan penambahan pati P0 (0%) sebesar 4,5% kemudian berturut-turut P1 (0,50%), P2 (1%), P3 (1,50%), P4 (2%) sebesar 4,23%, 4%, 3,72%, 3,48%. Pada kesukaan tekstur yogurt nilai tertinggi pada P3 dengan skor 3,8% dan nilai terendah yaitu P0 dengan skor nilai 3,13%. Penambahan pati tidak memberikan pengaruh (P>0,05) terhadap warna, rasa dan aroma yogurt. Berdasarkan hasil penelitian dapat disimpulkan bahwa penambahan pati talas 1,50% pada masa inkubasi 18 jam suhu ruang dapat menghasilkan yogurt yang optimal ditinjau dari sineresis dan sensori yogurt.

The purpose of this study was to determine the concentration of urine solution as a watering medium and organic fertilizer on the productivity of hydroponic corn fodder. The research materials were corn, sheep urine, and water, while the method used was field experiments. The treatments, namely T0 (0% urine), T1 (5% urine), T2, (10% urine), T3 (15% urine), T4 (20% urine). The variables were the percentage of germination, percentage of normal sprouts, number of leaves, plant height, fresh production and dry matter production. The data obtained were analyzed using analysis of variance, if there is an effect, then continue with the LSD test. The results showed that the treatments had a very significant effect (P <0.01) on the percentage of germination, percentage of normal germination, number of leaves, plant height, fresh production, and dry matter production. The highest germination percentage was found in T1 (91.60%), normal germination percentage T1 (86.78%), number of leaves T1 (3.0), plant height T0 (31.6 cm), forage production T1 (646.6 grams), dry matter production T1 (568.41 grams). Based on the results, it was concluded that watering with 5% concentration of sheep urine solution gave the best value for the productivity of hydroponic corn fodder.

The material of this research were corn and water. The method used was experimental field using Completely Randomized Design (CDR) with 3 treatments and 5 replications. The treatment used is P1 (1 time watering / day), P2 (2 times watering / day) and P3 (3 times watering / day). The variables observed in this study were. Percentage of germination, percentage of  normal germination, flant production, dry material production, organic matter  production, crude protein production and gude fiber production. Based on the results of the research shown that the productivity of corn feed with various watering treatments gives a very real effect (P <0.01) on the percentage of germination, normal germination, plant production, DM production, OM production, CD production and CF production. The highest percentage of germination on treatment P3 (95.80%), highest percentage of  normal germination on P2 (94.63%), highest plant fresh production on P3 (420.80 gram), highest dry matler production on  P3 (364.82 gram), highest OM production on P3 (357.68 gram), CD production  on P3 (66,51 gram) and CF production on P3 (82,74 gram). The conduded of this research were seed watering frequeney 3 times/day gave highest productivity of corn fodder (Zea mies) by hidropinic system.
