Abstract

Purple sweet potato (Ipomoea batatas L. Poir) anthocyanins is a source of natural colorant which has functional characteristic such as antioxidant, antibacterial, antimutagenic and anticarcinogen functions. The weaknesses of purple sweet potato anthocyanins are easily to degradation by pH, temperature, and light, but it can be improved by adding carrier agent. Acetilated starch is one of modified starch that has potential to be a carrier agent because of its ability to minimize decreasing active compound. The methodologies of the research were preparation and characterization of raw material, determination of the ratio of slurry and starch acetate carrier agent (10: 1; 10: 2 and 10: 3), application of starch acetate as anthocyanin carrier agent of slurry, filtrate and purple sweet potato pulp, and powder anthocyanin stabilized test to temperature and pH. The composition raw based material contained moisture content (79.09 - 93.51%), carbohydrates (5.63 - 20.18%), starch (4.96 - 19.22%), and anthocyanin content of 7.74 - 11.58 mg/100 g. The ratio of slurry and starch 10:1 gave Chroma of 18.48 and oHueof  334.75.

Abstract

Knowledge is an important asset that is easily lost. This loss process has a significant impact on plantation research organizations whose research takes a long time. This research aimed to develop an ontology model for recording knowledge about oil palm varieties. In order to save knowledge, in this research nine oil palm varieties were modeled into ontology using the Web Ontology Language (OWL). Any information in oil palm varieties can be sorted and grouped into classes, object properties, data properties, or data expressions. The relationship between data in oil palm varieties can be well represented using ontology. Based on the results from HermiT reasoners, the ontologies with 43 classes are consistent. Information in the ontology of oil palm varieties can be easily rediscovered using the description logic query (DL-Query). The model produced from this research can be used as an initial model in designing knowledge management systems and ontology-based oil palm expert systems.Keywords: ontology, OWL, oil palm seed, knowledge management

Abstract

From a crop production perspective, plastic mulches can increase yields, extend the growing season, reduce weed pressure, increase fertilizer use efficiency, conserve soil moisture, and increase soil temperature. A major limitation of polyethylene mulch involves disposal of mulch material following use. Recently, biodegradable mulch films have been viewed as a more sustainable ecological alternative to plastic polyethylene mulch. In an effort to cope up with the severe and continuously growing agricultural plastic waste problem, biodegradable film was fabricate using natural waste (corn husk) as reinforcing agent and the film fabricated was used to produce biodegradable mulching fim (Biomulch). In this research, the biomulch of the corn husk and Linear Low Density Polyethylene (LLDPE) produced by extrusion and calandering method with a width of 25 cm has been made. Biomulches were made of corn husksby concentration of: 5, 10 and 15% (% w/w). Proximate and fiber analysis were conducted to determine the composition of corn husks. The biomulches were produced were analyzed by mechanical, thermal, microstructure, morphological, and functional group properties.The results showed that the mechanical characteristics decreased with the addition of cornhusk concentration on biomulches, and concentration 5 %  had the highest mechanical characteristics with tensile strength of 14.52 MPa, elongation at break of 358.10% and modulus of elasticity of 0.37 GPa.

Abstract

Sikka District is an area with a dry tropical climate. Most of the plants especially food crops in Sikka District depend on rainfall. The lack of rain coupled with the weather anomalies occurring in Sikka District make Sikka District categorised in the area threatened by food insecurity.  Food crop cultivation often experiences obstacles, one of which is in determining the suitability of agricultural land for the advancement of certain food crops because the productivity of food crops depends on the quality of the area used. Therefore, this study aimed to develop a smart decision support system to determine land suitability with food crops. This study used a fuzzy analytic hierarchy process to determine the value of alternatives based on parameters that affect the relevance of the land with the type of food crop.  The results showed that corn food crops were the best alternative crop with a value of 0.339 of the three alternative food crops studied and then use the method fuzzy inference system to calculate the amount of land suitability. Kopong Village and Geliting Village were the best villages with land suitability values 81.Keywords: fuzzy analytic hierarchy process, fuzzy inference system, intelligent decision support systems, land suitability

Abstract

Areca catechu contains tannins compounds acting as antioxidants. Extraction process is required to obtain these compounds from areca nut. Pretreatment before extraction using Pulsed Electric Field (PEF) has shown improvement of yield as well as the quality of antioxidant extracts compared with control. The experimental design of this research was Factorial Random Design with two factors. The first factor was frequency of PEF with three levels of 1, 1.5, and 2 kHz and the second factor was PEF application time with three levels of 20, 25, and 30 seconds. The extract of areca seed from PEF extraction with combination of frequency and time of PEF using magnetic field 450 v/cm did not provide significanty different yield and quality. The selection of best treatment was based on the economic aspects and analysis of variance, since there was no significant difference between each parameter and treatment. The best frequency and duration of PEF on yield and antioxidant quality of areca nut extract were 1 kHz and 20 second with a yield of 5.6%; moisture content of 7.78%; IC50 value of 277,56 ppm; and tannins content of 442.36 mg GAE/g. FTIR spectrophotometric analysis results showed that the resulting absorption has a functional group that supports the presence of tannins.Keywords: fresh areca nut, electroporation, electrical pulse
