Abstract

ABSTRACTDaluga (Cyrtosperma merkusii Hassk) Schott is one type of plant tubers that have a highcarbohydrate content, but its use is limited because of limited tecnohologi owned by the public.Analog Rice is one of the solutions can be developed either in terms of the use of a new food source orto diversify food. The research objective is to get the right concentration of CMC in the manufactureof analog rice flour daluga bulbs. The first phase of the treatment of the old flour soaking slicedtubers daluga the pristine 1 % NaCl solution for 60 and 120 minutes. Further analysis of oxalic acid,oxalic acid treatment followed pads low second stage of rice manufacturing are analog to thetreatment CMC concentration addition. Treatment A = (100% flour daluga : 0% CMC), B = (99.6%flour daluga : 0.4% CMC), C = (99.2% flour daluga: 0.8% CMC), D = (98.8% flour daluga : CMC1.2%), E = (98.4% flour daluga : 1.6% CMC). Organoleptic test results, treatment was continuedwith an analysis of selected physical and chemical properties. Results for flour daluga an average of0.35-0.52% oxalic acid content and chemical composition of the water content of 11.97%, ash contentof 2.4%, 0.89% fat content, protein content 1.11% and carbohydrates conten of 83, 65. Analog Forrice, the chosen treatment CMC concentrations are treatment B = (99.6% flour daluga: 0.4% CMC).nalisis With the results of physical and chemical properties of the analog rice yield 53.52%, colorsrice 70% , 43%, 179.96% water absorption, rehydration time of 7 minutes, water content 7.88%, ashcontent of 2.6%, 5.42% fat content, protein content 0.66%, and carbohydrates conten of 83, 44%.Keywords: Bulbs daluga, oksalate, analog rice, food security

Abstract

ABSTRACTDrinks snacks is one product with a sweet taste that can be found, one in the traditional market town ofManado. In the manufacturing procces, manufacturers often use artificial sweeteners to replace naturalsweeteners in order to lower production costs. Artificial sweeteners are the most widely used is the cyclamateand saccharin. In some studies it was found that the use of artificial sweeteners that do not qualify will causecarcinogenic diseases. This study aims to analyze the levels of artificial sweeteners as food additives inbeverages snacks sold in the traditional market town of Manado. The study uses survey. The samples used weresnacks beverages like cendol ice, teler ice, coconut ice, and syrup ice sold in six traditional market town ofManado. This location is chosen according to the overall market located in the market town of Manado PerumPaniki, Paal 2, Tuminting, Bersehati, Karombasan, and Bahu. Sampling as many as 16 samples in whichsamples cendol ice, teler ice 4 samples, coconut ice 1 sample, and syrup ice 2 samples. Conducted a qualitativeanalysis of samples for the presence of cyclamate and saccharin in content of the sample followed by aquantitative analysis to measure the level of artificial sweeteners contained in the sample. The results showedthat in 16 samples of drinks snacks that are six traditional market town of Manado, containing no artificialsweeteners saccharin and two samples of syrup containing artificial sweetener cyclamate. Samples containingcyclamate syrup is red syrup and yellow syrup. Cyclamate levels found in red syrup of 931.98 mg / kg andyellow syrup of 848.65 mg / kg. According to the ISO limit of safe consumption of cyclamate in similar syrup is500 mg / kg, so it can be concluded that cyclamate levels have exceeded the allowed threshold value.Keywords: Snacks drinks, artificial sweeteners, cyclamate, syrup ice

Abstract

ABSTRACTThis research aims to study techniques bioethanol production from cassava to produce ethanol from cassava and determines the quality of the bioethanol produced by analyzing the ethanol content and pH as well as knowing the yield of bioethanol produced from the process is used. The results have been known to a variety of constraints in the production process from raw material storage, fermentation and distillation that can affect the end result in obtaining bioethanol from cassava. By using 5 kg of cassava feedstock with 3 times distillation process which has produced 215 ml of ethanol to 53% ethanol content and pH 6.902; 185 ml of ethanol to 74% ethanol content and pH 6.927, and 130 ml ethanol with 49% ethanol content and pH 6.573.Keywords: Bioethanol.

The sample collecting by purposive sampling with thenumber of respond is 40 women farmer. Data were analyzed descriptively and are presented intabular form.The results of this research showed the contribution of working women in the palm sugarfarming family in the Rambunan and Sawangan village more devoted to work in farming thanoutside of farming. This is evident from the percentage of total working time of women infarming palm sugar in those villages which shows the results greater than jobs outside palmsugar farm.Based on an average flow of time and the percentage of women working in farming palmsugar obtained showed the greatest results, the contribution of the highest female labor in palmsugar farms in the Rambunan and Sawangan village is the sales activities (print sugar).Contribution of working woman in palm sugar farming activities in the rambunan andsawangan is the filtering activities with average of time obtained from the event shows thesmallest results.Suggested considering women workers in palm sugar farming give contributes largeenough, Processing of farm products more developed (variable) to increase farm family incomeand be able to utilize labor from outside the family, so the women farmers with her family willalso be increased. Needs to be continue, especially regarding the effect of contribution of theworking women to farm families income.
