The research aims to observe the effect of addition wild honey (Apis dorsata Fabr.) on pH and organoleptic values of ultra high temperature milk (UHT). The research was  done using an experimental method using a non-factorial completely randomized design with five levels using SPSS 16. Different concentrations of wild honey (A1= control; A2= 5%; A3= 10%; A4= 15% and A5=20%) were used. The data was statistically analyzed using analysis of variance (ANOVA) with 5% significance level and further processed with Duncan's Multiple Range Test (DMRT). Organoleptic tests for colour, taste and overall preference were also done using qualitative tests (scores). The value of pH gave a significant value (P<0,01) between treatment. The higher the use of  wild honey concentration, the lower the pH value produced. The higher the concentration of wild honey, the higher the organoleptic value. The best treatment in terms of colour, taste, and level of preference was observed in the sample with the 20% honey concentration, each of which resulted in an average score of 4.

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

The effect of durian flesh on the characteristics of Gayo Arabica wine coffee quality by fermentation methods has been investigated. This study aims to determine the effect of giving durian flesh to the characteristics of the Arabica Gayo wine coffee and to determine the optimum addition amount of durian flesh. This study used a completely randomized design (CRD) with 5 treatments and 3 replications. Data analysis using ANOVA was then continued with Duncan's New Multiple Range test (DNMRT) at a significance level of 5%.  The treatments were: the addition of durian flesh 0, 25, 50, 75, and 100 g to 1000 g of a coffee cherry. Based on the sensory test, the highest score was obtained by adding 0 g of durian flesh to 1000 g coffee cherry (Score: 76.5)  which was followed by the addition of 75 g of durian pulp to 1000 g coffee cherry (score: 72.75).  The results showed that the addition of durian pulp had a significant effect on the ash content and caffeine content but did not significantly affect the water content.

According to BPOM (2006), soymilk is an emulsion product that is extracted from boiled and ground soybeans with the addition of water. Soymilk is a food product that has several advantages including being cheaper than cow's milk and high nutritional value. The process of making soymilk will affect the quality produced. Soaking soybeans aims to soften the cellular structure of soybeans so that they are easy to grind, provide better dispersion and suspension of soybean solids at the time of extraction and make it easier to peel the soybean skin and result in mold that can ferment soybeans without skin. The research design used was factorial completely randomized design (RALF) with two treatment factors and three replications. The first factor is the immersion temperature (A) consisting of A1 = 30 ° C, A2 = 50 ° C. The second factor is the immersion time (B) consisting of B1 = 9 hours, B2 = 12 hours and B3 = 15 hours. The data obtained were analyzed using the Analysis of Variance (ANOVA) statistical test at a 5% level of confidence using version 9 of the SAS (Statistical Analysis System) program. The treatment that had a significant effect was followed by the Duncan Multiple Range Test (DMRT) difference test. The laboratory examination results showed that the average value of total dissolved solids of soymilk 10.33-15.67% (SNI TPT min 11.50%); the average pH value of soymilk is 6.03-7.02 (SNI pH 6.5-7.0); and soymilk total protein average value 1.07-1.50% (SNI protein min 1.0%). A1B1 treatment (30 ° C, 9 hours) is the best treatment because it meets SNI standards for soybean juice (pH 7.02; TPT 15.67%; protein 1.27%)

The sour taste of kefir ice cream is less attractive with consumers, so it is necessary to add sweeteners. Dates can be used as a natural sweetener in making kefir ice cream. The aims of this research is to determine the effect of sugar substitution with dates puree on overrun, melting rates, viscosity, pH value and organoleptic properties of kefir ice cream. The method used in this research was an experimental with Completely Randomized Design (CRD) with 5 treatments and 4 replications. Overrun, melting rates, viscosity and pH values were analyzed by ANOVA test and followed by Duncan Multiple Range Test, meanwhile organoleptic characteristic were analyzed by Kruskall Wallis test and followed by Mann-Whitney test. The results showed that the substitution of sugar with dates puree as a sweetener had a significant effect (p<0.05) on overrun, melting rates, viscosity and pH value of kefir ice cream. Substitution of sugar with dates puree had a significant effect (p<0.05) on sweetness, sourness, brownish color and softness of kefir ice cream. The sugar substitution with dates puree 25%: 75% (T1) had the best overrun, melting rate as well as the organoleptic characteristic because it was able to reduce the sour taste of kefir ice cream

The study aimed at evaluating the functional performance of a developed portable ginger rhizomes slicing machine. The study was conducted at various levels of impeller speed, impeller gang and slicing compartment in the Department of Agricultural and Bioresources Engineering, Ahmadu Bello University, Zaria, Nigeria between April 2018 and June 2018. A  factorial experiment in a Completely Randomized Design (CRD) was used.  The indices for the performance evaluation were the Slicing Efficiency and Throughput Capacity. The machine was powered by one horse power petrol engine and ginger moisture content of 77.44%. Data collected were subjected to statistical analysis using Analysis of Variance (ANOVA) to test the significance level of the experimental factors and their interactions; and those found significant were further subjected to Duncan Multiple Range Test (DMRT) for mean separations at (P = .05), respectively.  The results showed that, the ANOVA for all the factors evaluated and their interactions on Slicing Efficiency were highly significant at (P ≤ .01). However, the ANOVA for the factors evaluated on Throughput capacity were highly significant but interaction between type of compartment and speed of impeller was not significant at (P =.05).

Abstract Tilapia is a freshwater fish species are widely cultivated in Indonesia. Tilapia production continues to grow every year, the average increase in the number of experienced production tilapia reaches 22.24% in the 2010-2011 range. Tilapia production in 2011 reached 567.449 tons and was second aquaculture production by major commodity after seaweed. This study aimed to determining differences in extract ether digestibility, organic matter, and energy on feed derived from different factories in tilapia (Oreochromis niloticus) using surgery techniques. The research design is using completely randomized design. The variables were measured extract ether digestibility, organic matter, and energy in tilapia feed. Analysis of the data processed using Analysis of Variance (ANOVA) to determine differences in treatment given. If there is a difference then followed by Duncan's Multiple Range Test with a significance level of 5%. Based on the findings that there were no significant differences (p>0.05) in extract ether , organic matter, and energy digestibility of the feed value of tilapia. The results stated that the feed treatments A, B and C efficiently digested by tilapia.
