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.

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%)
