Abstract

Pectin is an essential polysaccharide that is usually found in the skin of various fruits and vegetables. It acts as a gelling agent and stabilizer in many food and pharmaceutical industries. This study focuses on the potential of grapefruit peel as a source of pectin. Pectin is isolated from hot grapefruit peel powder (albedo). The aim of this study was to extract pectin from grapefruit peel (albedo), and central composite design (CCD) together with the numerical optimization method of response surface methodology (RSM) was used to optimize the processing parameters, including temperature (60, 80 and 100 ° C), pH (1.5, 2.0 and 2.5 ) and time (60, 90 and 120 min) The findings show that the studied parameters have a major impact on the pectin yield. The resulting second-order polynomial model thoroughly explains the relationship between input and output variables and how the data is varied. The highest pectin yield was 28.45% at optimal conditions achieved: temperature: 100° C; pH: 1.5; and extraction time: 120 minutes. Temperature, pH, and extraction time have their own large impact on pectin yield which has a significant effect.

Abstract

The diversification limitation of exploiting tempe as an alternative nugget raw materials, substitution of meat and fish, and also to optimalize the very abundance resource, so it is necessary to do the right processing to the alternative food resource, which meant to give an additional point. Produce a liked product, also the adjustment of technology, and the cost that reached by the society. The aim of this reseach is to know the kind of glue material which can produce nugget tempe with the best chemical and organoleptic propertics. This research consit of 4 treatment; A1 (tempe nugget from bread powder), A2 (tempe nugget from tapioca), A3 (tempe nugget from sagu), A4 (tempe nugget maizena powder). Water convcentration analyse using oven method. Product was tested by organoleptic test (taste, smell, and tecsture). The result on water concentration analyse, that the smallest water concentration shown by A2 about 161,55% between from treatment A1 abaout 191,75%, A3 abaout 180,02% and A4 182, 45%. The result on organoleptic the teste of A1 product is the most like (75 %) between A2, A3 and A4 treatment. The smell of A2, A3 and A4 is the must like (67 %). And the best tecsture is all treatment.The result of this research is expected to give benefit in supporting the effort saking the alternative nugget glue material by using tempe which owning a high nutrition value. This research it is expected to find a kind if nugget tempe with the good glue, good taste and high nutrition value.

Abstract

The important reason is that botanical insecticides didn’t cause environmental damage and not harmful to human health. As we know, tobacco leaf extract is one of many plant extract that use as botanical insecticides. It can kill fruit fly (Drossophyla melanogaster) that suck domestic plant. On the other hand tobacco leaves extract use as wound therapy also. Those effects are caused of the chemical compound such as alkaloid, saponyn, flavonoid and polyfenol.The objective of this study is to know the impact of tobacco leaf extract to development of D. melanogaster. Beside that, we observe the effective volume that causes optimal impact. Therefore we mix four type of tobacco leaf extract on D. melanogaster medium. In this case we apply 10 ml (P1), 20 ml (P2), 30 ml (P3) and 0 (P0). Then we observe the mortality. Further the mortality data is compiling by F analysis and LSD.The result shows that tobacco leaf extract caused negative impact to development of fruit fly on all stage of D. melanogaster (larvae, pupae, adult). The most effective impact seems on P3. Hopefully, the result of this study might useful to farmer that use botanical insecticide especially tobacco leaf user. So, user will have more advantages, because it didn’t harmful to human health and environmental.

Abstract

The growth rate of Hermetia illucens larvae in the bioconversion of organic waste is influenced by the media and environmental conditions where the BSF lives. This study aims to determine the effect of the feed formula on the growth of Hermetia illucens larvae in the bioconversion of organic waste. This research method was carried out by rearing BSF larvae, making BSF feed formulas, determining larval length, determining the weight and weight of BSF cassava. The results showed that the feeding formula from fish waste, tapioca waste with a chopped diameter of 10,20,30 mm gave a significant effect on the growth of BSF larvae (larval length, larvae weight) and BSF maggots. The provision of 20 and 30 percent fish waste has a higher weight and length with a chopped diameter of 20 and 30 mm.

Abstract

This study aims to synthesize nanoparticles of Javanese bark extract (Lannea coromandelica) coated with chitosan and characterization of the synthesis results. The extraction of Javanese bark (Lannea coromandelica) was carried out by the maceration method using a 70% ethanol solvent. The bark extract of the Javanese wood plant (Lannea coromandelica) was synthesized to form chitosan-coated nanoparticles using the ionic glassing method and the synthesis results were characterized using X-Ray Difraction (XRD). The results showed that the synthesis of nanoparticles of the bark extract of the Javanese wood plant (Lannea coromandelica) coated in chitosan has a nanoparticle size of 24.9 nm.
