Abstract

This community service (PPM) program was conducted on Kabung Island, Karimunting Village, Sungai Raya Kepulauan District, Bengkayang Regency, West Kalimantan. The partners involved were community groups representing the northern, southern, western, and eastern parts of Kabung Island. The partners were vegetable and plantation crop farmers who experienced difficulties in controlling pests on their crops. This PPM activity aimed to provide partners with additional knowledge and skills in pest control using local natural resources. The program consisted of several stages: coordination, outreach, technical training, and activity evaluation. 100% of participants experienced increased knowledge and skills in making and applying pest traps. Furthermore, increased productivity and crop quality were observed several months after using the pest traps. Based on these results, it can be analyzed whether partner income will increase if the pest trap application is implemented sustainably in crop cultivation on Kabung Island.

Abstract

Edible films represent biodegradable food packaging. Potential material used as an edible film is biocellulose nata de coco, but flour made from purple yams needs to be added to increase the solubility of composites in water. The purpose of this research was to study the effects of purple yam flour and glycerol concentrations on moisture, ash content, thickness, barrier properties (WVTR), and mechanical properties biocellulose based edible film. Edible films made with the proportion of slurry biocellulose and purple yam flour were 100: 0; 98: 2; 96: 4% and glycerol were added 0, 1, and 2% and aquades was added to the total volume of 200 ml. The suspension is put in a mould and dried in a 40 ° C oven for 24 hours. Increased concentrations of purple yam flour at biocomposite and glycerol reduce tensile strength and modulus of elasticity, increase the thickness of the edible film. Interaction between biocellulose-purple yam flour and glycerol at high concentrations reduced mechanical strength as a result of network integrity disruption. Interaction between biocellulose-purple yam flour and glycerol reduced moisture content but increased ash content. Glycerol concentrations that were too low and high cause antiplastizicer properties that affected the elongation at break and WVTR edible film. This study demonstrated that proportion of biocellulose-purple yam flour 98:2% and glycerol 1% has good potential for producing the edible films
