Oil palm trunks can produce quite a lot of sap water, which is approximately 10 per day for 1 month for 1 oil palm tree that is uprooted, currently, there is not much optimal processing of palm oil with an economical selling price, for this reason, it is necessary to develop functional foods. This study aims to determine whether palm sap can be used in the manufacture of symbiotic beverage products with optimum chemical, microbiological and organoleptic qualities. The study was arranged using a non-factorial Completely Randomized Design (CRD) method with 3 treatments of incubation time, namely 12 hours, 24 hours, and 36 hours with each treatment using 6 replications so that 18 experiments were carried out. The best treatment by SNI 2981:2009 was obtained at an incubation time of 24 hours, namely with a pH of 5.2, water content is 82.50%, total dissolved solids is 17.33%, the lactic acid content is 0.81%, a total lactic acid bacteria of 2.8 x 108 and produces a minimum dense texture with sufficient acidity. The organoleptic aspect of taste and aroma at 24 hours of incubation time was favored or acceptable to consumers with a taste score of 3.3b and aroma of 3.3ab (scale 1-5) in the hedonic rating test. Meanwhile, at 36 hours of incubation, consumers did not like it with a taste score of 2.2a and aroma of 2.1a. This is because the longer the fermentation time can increase the acidity of the product which causes the distinctive taste and aroma of palm sap to increase.

Indonesia is a large world coffee producer, which is currently followed by the proliferation of coffee shops that provide specialty coffee. Arabica coffee is a type of coffee that is considered to have the better taste among other types of coffee. Sidikalang is one of the coffee producing areas in North Sumatra but has not been fully explored. Traditional processes are still widely used, even though the standard post-harvest process for Arabica coffee is divided into two, namely the wet process and the dry process. This research aims to analyze and compare the sensory and physicochemical characteristics of traditional processing with standard processing of Arabica coffee, especially Sidikalang Arabica coffee. The physical quality of the traditional process and natural process is in category 2 while the wet process is in category 1 based on the Indonesian National Standards (SNI) 2008 for coffee beans. The caffeine content of all treatments meets the 2004 SNI standard of below 2%. Carbohydrate levels are relatively low, with an average value below 30%. The Percent Extraction (PE) in espresso meets standard values ranging from 18% to 22%. Wet processes tend to be very popular in terms of fragrance, acidity, bitterness, and body, while natural processes and traditional processes are dominant in terms of fragrance.

Processing palm fruit produces crude palm oil. Crude palm oil levels continue to increase during the fruit ripening process. The parameters used in determining the maturity criteria for palm oil harvest are color change and fruit breaking off from the bunch. Harvest quality is determined by the mature fraction. One of the problems that occurs in palm oil factories is the selection of palm fruit bunches (FFB), which are divided into three classes, namely unripe, ripe and over ripe. Selection of FFB is done manually, namely visually. The quality of palm oil is greatly influenced by the level of ripeness of the fruit at the time of harvest and post-harvest handling until the mill. This research aims to evaluate the use of variations in palm fruit maturity used in PKS which are related to yield and quality as well as oxidative stability and color. The research results showed that the variation in palm fruit maturity used resulted in the highest yield, namely 17% in P2. The quality of crude palm oil obtained from variations in fruit maturity shows different results, where the highest free fatty acid content of 2.57% is located in P2, namely a mixture of ripe and overripe fruit, while the highest water content is found in P2, namely 0.65 %. P3 has the highest impurity content of 0.68%. The oxidative stability and color obtained from using variations in fruit maturity that were heated for 24 hours decreased in value to red and yellow

Arabica coffee (Coffea arabica L.) is a coffee with the best taste compared to other types of coffee. The most ideal altitude for cultivating Arabica coffee is between 1200 mdpl -1400 mdpl, but Arabica coffee grows and produces well at an altitude of 900 mdpl - 1700 mdpl which is an ideal habitat for cultivating Arabica coffee. If Arabica coffee is planted in the lowlands, especially at an altitude of 600 - 700 mdpl, usually the production and quality are low and susceptible to leaf rust disease. This study aims to analyze the characteristics of the physicochemical properties, namely reducing sugar, extract content and caffeine content of Gayo Arabica coffee at an altitude of 1500 mdpl and 1600 mdpl. This study uses the Completely Randomized Design (CRD) Non-Factorial method with 2 levels of altitude treatment, namely 1500 mdpl and 1600 mdpl with 4 replications. The results of this study indicate that an altitude of 1500 mdpl has an average of 43.49013% and 1600 mdpl has an average of 51.10553% significantly affecting the coffee extract content. At an altitude of 1500 mdpl, it has an average of 0.3504% and 1600 mdpl has an average of 0.3792% which has no significant effect on coffee reducing sugar. At an altitude of 1500 mdpl, it has an average of 0.74625% and 1600 mdpl has an average of 0.5095% which has a very significant effect on coffee caffeine content.
