Abstract

The purpose of this research is to determine the optimum properties of biodegradable plastic made from banana weevil starch with the addition of straw cellulose as reinforcement. This research was conducted using Completely Randomized Method (CRD) with four treatments and four replications. In this study were the addition of straw cellulose with a ratio of starch and cellulose 1:0; 1:0,5 ; 1:1 and 1:1,5. Tests were carried out on strong tensile strength, elongation at break, biodegradation, swelling and water vapor transmission rate. The data obtained were analyzed statistically using analysis of variance (ANOVA). The addition of straw cellulose had a significant effect on the manufacture of biodegradable plastics. The result were biodegradable plastic increase tensile strength, decreases elongation at break, increase biodegradation and air resistance, reduces the rate of water vapor transmission. Biodegradable plastic with the best treatment is the ratio of starch starch ratio of 1 : 1.5 cellulose. The best result biodegrabable plastic has for tensile strength value of 9.56 MPa, elongation 6.8%, complete biodegradation on day 6, swelling 41.51% and WVTR 0.0156%.

Abstract

Penelitian dilaksanakan untuk mengetahui karakteristik dari plastik biodegradable berbahan dasar pati bonggol pisang dengan selulosa jerami. Penelitian dilakukan dengan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Pada penelitian ini melakukan penambahan selulosa jerami dengan perbandingan pati dan selulosa 1:0; 1:0,5 ; 1:1 dan 1:1,5. Pengujian dilakukan terhadap kuat tarik, perpanjangan putus, biodegradasi, pengembangan dan laju transmisi uap air. Data dianalisis secara statistik dengan menggunakan analysis of variance (ANOVA). Penambahan selulosa jerami berpengaruh terhadap pembuatan plastik biodegradable. Hasilnya adalah plastik biodegradable meningkatkan kekuatan tarik, mengurangi perpanjangan putus, meningkatkan biodegradasi dan hambatan udara, mengurangi laju transmisi uap air. Plastik biodegradabel dengan perlakuan terbaik adalah rasio perbandingan pati pati 1 : 1,5 selulosa. Plastik biodegrabable hasil terbaik memiliki nilai kekuatan tarik 9,56 MPa, perpanjangan 6,8%, biodegradasi lengkap pada hari ke 6, pembengkakan 41,51% dan WVTR 0,0156%.

Abstract

One efficient method to prevent infections spread by mosquitoes is to use repellent. However, when used regularly over an extended period, insect repellents containing DEET commonly available on the market may induce adverse effects such as hypersensitivity, irritation, and hives. Pineapple and sweet orange peels can be utilized as natural ingredients in mosquito-repelling lotions because they contain various secondary metabolites, including tannins, saponins, flavonoids, alkaloids, steroids, and essential oils. This study aimed to find the optimal concentration of pineapple peel extract based on the characteristics of the produced mosquito repellent lotion. The experiment used a completely randomized design (CRD), producing 15 experimental units with five treatments—pineapple peel extract concentrations—each with three replications: 2%, 3%, 4%, 5%, and 6%. The lotion with a 6% concentration of pineapple peel extract (LNJ5) was selected due to its homogenous physical characteristics, pH of 7.89, spreadability of 6.98 cm, viscosity of 2131.02 cP, and mosquito protection rate of 88.64%. The lotion had a yellowish-brown color, a faint pineapple and orange scent, and a descriptive organoleptic evaluation that panelists found pleasing
