The purpose of this research was to evaluate the influences of the sugar addition and the yeast starter concentration used in wine processing on the characteristic of red dragon fruit wine. The research was experimental research that designed using Randomized Block Design. Two factors were experimented, namely the sugar concentrations (22oBrix, 25oBrix and 28oBrix) and yeast starter concentration (5%, 10% and 15%). The experiment was carried out in two block experiment, so that totally was done 18 unit. The result of this research showed that the interaction treatments of the addition of sugar and the addition of yeast starter concentration significantly affected the ethanol content, reducing sugar content and the total phenol of red dragon fruit wine. Otherwise, the interaction treatments did not significantly affect the total soluble solid and the acidity of the wine. The organoleptic test showed that the panelist prefered the wine which produced with 28oBrix sugar content and the addition of 15% yeast starter. The etanol content, reducing sugar content, total soluble solid, pH and the phenol content of this wine were 11.24%; 1.756%; 12.10oBrix; 3.75 and 1.637 mg/100 g, respectively.

Control Application

There are many of rice field which is located near the industrial area. The industrial waste contains heavy metals (chromium) which will cause contamination of rice if the waste isn’t treated properly. The used of chemical fertilizers can cause chromium contamination. It needs an effort to do remediation, such as using phytostabilization mechanism. This research aimed to determine the role of chelator in chromium phytostabilization and its influence on the growth and quality of rice. The study was conducted in Waru village, Karanganyar in May to October 2018. This research was factorial design used completely randomized block design with two factors, namely chemical fertilizers and chelator (Agrobacterium sp. I26, and manure). The parameters observed are chromium content and uptake by plant tissues (roots, shoot and rice), plant height and a number of clumps. Research output was without chemical fertilizer-chelator Agrobacterium sp. I26 that can increase the chromium uptake in roots as big as 95.38 %, increased up to 10 % in the shoot and decreased up to 92.38 % in rice compared to control. Application of Agrobacterium sp. I26 can be recommended to produce good quality and quantity of rice (good growth and free from harmful pollutants such as chromium metal).

Two Factors

Rice is a rice-producing food crop which now plays an important role in economic life in Indonesia. Namely rice as a staple food is very difficult to replace by other staples. Among them are corn, tubers, sago and other carbohydrate sources. So that the existence of rice is now a top priority for the community in meeting the needs of carbohydrate intake that can be filling and is a source of primary carbohydrates that are easily replaced into an energy source. Rice as a staple food is consumed by approximately 90% of the total population in Indonesia for daily essential food (Saragih,2001). How to plant with the jajar legowo system has the advantage that the plants are on the edge so that optimal sunshine can cause plant productivity to be high, facilitate weed control and pests / diseases, use of fertilizer more effectively and the availability of empty space for regulating water channel circulation on land (Sirrapa, 2011). This research was conducted using Factorial Randomized Block Design (RBD) method, which consisted of two factors and each factor consisting of 3 levels repeated 3 times, namely: J1: Conventional,J2: Jajar Legowo 2: 1,J3: Jajar Legowo 4: 1. Factor II: Varieties with 3 levels, V1: Situ Bagendit, V2: Ciherang,V3: IR-64. Of the two factors 9 combinations of treatments were obtained and repeated 3 times. Data obtained from observations were calculated by analysis of variance with the Fisher test (-F test at the level of 5% and 1%), if there were significant differences, it would be followed by the Smallest Significant Difference test (LSD 5%). The treatment of the legowo 4: 1 row system and the ciherang variety (V2J3) produces a better value than other treatments.

This study aims to determine the concentration of starfruit juice and dragon fruit peel on the quality of jam. The experimental design used was a one-factor Randomized Block Design (RAK) with six treatments and three replications to obtain 18 samples. The treatments were the concentration of starfruit juice and dragon fruit peel extract with P1 (100% : 0%), P2 (85% : 15%), P3 (70% : 15%), P4 (55% : 45%), P5 ( 40% : 60%) and P6 (25% : 75%). Parameters observed were vitamin C levels, antioxidant activity, spread, and color as well as sensory tests (color, aroma, and taste). Data analysis results were tested by analysis of variance at a significance level of 5% using Co-Stat software. If there is a significant difference, then the orthogonal polynomial further test is carried out, while the physical and sensory tests are further tested using the Honest Significant Difference test at a significance level of 5%. The results showed that the concentration of star fruit juice and dragon fruit pulp did not have a different effect on vitamin C levels but had a significantly different effect on antioxidant activity, spread, and color. P6 treatment resulted in the highest antioxidant activity of 77.27%, 12.80 mg of vitamin C content, 10.1 cm of smearing power, and sensory properties that were acceptable to the panelists.

There is few people who like goat milk, that is why process of making goat milk into ice cream is needed. Therefore, a research has been done at Animal Production Laboratory of Husbandry Department, Faculty of Agriculture, University of North Sumatera, from April to May 2018. The design which used in this research is Randomized block design (RAK) with two factors: kefir concentration (P): (0%, 10%, 20%, 30%) and aging time (L): (6, 12, 18, 24 hours). Parameters which observed were overrun, melting time and organoleptic test (color, aroma, texture, taste). The results showed that the interaction between kefir concentration and aging time gave a significant effect to organoleptic result of flavor and did not give significant effect to overrun, melting time and organoleptic results (color, texture, taste). The concentration of kefir had given significant effect to melting time and organoleptic results (color, aroma, texture, taste) and did not give significant effect to overrun result. The aging time gave a significant effect to overrun, melting time and organoleptic results (color, aroma, texture), and did not give a significant effect on organoleptic taste result. The best result was obtained in addition of kefir extract of red dragon fruit 30% with aging time aged 6 hours on ice cream made of goat milk.

Penelitian dilakukan mulai bulan Juli sampai dengan September 2010 menggunakan metode eksperimen di laboratorium. Rancangan yang digunakan ialah acak kelompok dengan tiga ulangan. Perlakuan yang diuji terdiri atas 10 klon kentang yaitu (1) 385524.9 x 392639.34, (2) 393077.54 x 391011.17, (3) 393077.54 x 391011.17, (4) 391011.17 x 391580.30, (5) 391011.17 x 385524.9, (6) 393077.54 x 391011.17, (7) 391011.17 x 385524.9, (8) 391011.17 x 385524.9, (9) 393033.54 x 391580.30, dan (10) Granola (kontrol). Hasil uji organoleptik menunjukkan bahwa keripik kentang yang memiliki skor antara 2,00-2,36 (kuning merata) untuk chips kentang ialah klon 7 (391011.17 x 385524.9) dan klon 8 (391011.17 x 385524.9). Kandungan gula reduksi dari kedua klon tersebut, yaitu masing-masing 0,029 dan 0,023% lebih rendah daripada kandungan gula reduksi pada klon-klon lainnya yang keripiknya berwarna gelap. Klon-klon tersebut memenuhi persyaratan kualitas dan berpeluang untuk digunakan sebagai bahan baku industri pengolahan keripik kentang. The objective of the research was to determine the quality of potato clones resulted from selection for potato chips. Quality test of 10 selective clones was determined. The research was conducted from July to September 2010, and was arranged in a completely randomized block design with three replications. Treatments consisted of (1) 385524.9 x 392639.34, (2) 393077.54 x 391011.17, (3) 393077.54 x 391011.17, (4) 391011.17 x 391580.30, (5) 391011.17 x 385524.9, (6) 393077.54 x 391011.17, (7) 391011.17 x 385524.9, (8) 391011.17 x 385524.9, (9) 393033.54 x 391580.30, and (10) Granola (control). The results showed that chips which had a score value between 2.00 to 2.36 (yellow uniform) for potato chips were clone 7 (391011.17 x 385524.9) and clone 8 (391011.17 x 385524.9). The reducted sugar content of these clones was lower (0.029 and 0.023% respectively) than the reducted sugar content of the other potato clones which had dark color.
