Abstract

Calamansi orange is a superior fruit that is being promoted for planting in Bengkulu Province. Calamansi citrus preparations have only a few variations, generally made into calamansi orange syrup. This research was conducted to make a new processed variation from calamansi orange juice to Nata de Citrus products and to optimize the nata fermentation medium based on glucose and nitrogen concentrations. This study used a factorial completely randomized design (CRD) with 2 factors. The first factor is the variation of glucose in the medium by diluting orange juice 0 times ( no diluting); 0.5 times; 1 times; 1.5 times and 2 times. The second factor is the variation of nitrogen in the medium obtained by adding 0.6% Ammonium Sulfate; 0.7% and 0.8%. The results were analyzed using ANOVA and for significantly different variables, further analyzed using orthogonal polynomial order 2. The optimum results were obtained at a glucose concentration of 1.76% (dilution of calamansi orange juice 1.65 times) and a nitrogen concentration of 0.17% (ammonium sulfate 0.8%).

Abstract

The objectives of primary education is to give students basic competence to develop their life as an individual, as part of a community and as citizen. On the other hand, the objective of a nature science in primary education is to give students competencies to develop their knowledge, skill, and attitude that is useful in their daily life. Nature science in primary education refers to knowledge rather science. It means that what is teach in primary education are practice things, useful to the living and then in any circumstances and any life aspects. The mission and objectives in teaching nature science in primary education is related to the environment problems in school environment as well as community environment problems in school environment around the students. The environment around the kids should have been used by the teacher to teach natural science because the environment itself the objective, source, and learning facilities. The manufacture of teaching natural science in primary education can be obtained by doing a meaningful learning process.
