Abstract

Minimally processed jackfruits can usually be found in traditional markets, but the fact found that jackfruit is sold unpackaged and the fruit is not fresh, some have even browned and are infested with flies. Refrigerator is usually applied, but this technology is relatively expensive and not all farmers/traders can afford it. Edible film is an alternative that is easily degraded and decomposed by natural composers plus zinc oxide (ZnO) which is a piezoelectric ceramic that has anti-microbial properties. The purpose of this research was to determine the effect of ZnO concentration on the characteristics of edible films and to determine the best concentration of ZnO and its effect on packaging in jackfruit. Variations in the concentration of ZnO used 0%, 3%, 9% and 12%. Observations on jackfruit were carried out at room temperature. Results showed the higher the concentration of ZnO, the better the ability of edible films with ZnO to maintain the quality and shelf life of jackfruit. Edible film with 12% ZnO was able to extend the shelf life of processed jackfruit for at least 5 days at room temperature . Keywords:  Hardness, Weight loss, Total dissolved solid, Microbial test, Water content.

Abstract

Plastic is one of the most widely used packaging materials. Plastic is made of chemicals that are highly toxic, and its use has produced a lot of waste that is bad for the environment and difficult to decompose. The global community is becoming more and more aware of the value of high-quality food, particularly when it comes to packaging that is safe for human health and the environment. Edible films can be used as an eco-friendly alternative to plastic food packaging options. As a material for packaging, edible film made of biopolymers has been created. This material can be made from biodegradable components and has qualities akin to those of ordinary plastics. When combined with zinc oxide (ZnO), a piezoelectric ceramic with anti-microbial properties, edible film degrades and decomposes readily. This study sets out to identify the effects of variations in zinc oxide nanoparticle concentration properties of edible films made from corn starch (Zea mays L.) and to establish the optimal zinc oxide nanoparticle concentration. ZnO concentrations ranging from 0% to 3% to 9% to 12% were used. The outcomes demonstrated that a concentration of 12% provided the optimal treatment for the properties of edible film. With the addition of 12% ZnO concentration, the edible film's properties improved the most in this investigation, showing 81.94% water resistance, 1.434 MPa tensile strength, and 38.46% elongation percent. The lowest biodegradability value was found in edible film with a concentration of ZnO 12%, within 14 days. The resistivity, tensile strength, and % elongation of the edible film increase with increasing ZnO content.

Abstract

Crude palm oil (CPO) is a raw material for making cooking oil that comes from palm oil, which is greatly influenced by the quality of oil palm fresh fruit bunches (FFB). Oil and carotene content in the FFB influence the quality of palm oil. The oil content is usually determined using a chemical method (Soxhlet extraction) which is time consuming and destructive. This research aimed to predict the oil and carotene content contained in oil palm FFB using partial least square (PLS). In this research, the sample used was the Tenera variety with a maturity of 140-160 day after anthesis (DAA) and 200-220 DAA. The nondestructive method involves recording images using an optical camera, which produces RGB and L*a*b* values. Results showed that PLS predicts the relationship between optical properties and oil and carotene content in palm oil. Non-destructive prediction results using PLS provided consistently correlation of L*a*b* values with estimated oil and carotene content in the FFB. Keywords: Non-destructive, Optical properties, Fresh fruit bunch, Oil palm.

Abstract

Gula merah tebu cetak merupakan produk olahan nira tebu yang dihasilkan melalui proses penguapan. Penambahan bubuk kayu manis pada gula tebu memberikan manfaat tambahan bagi kesehatan tubuh. Salah satu kriteria mutu gula merah tebu cetak adalah warna. Warna gula tebu cetak mengalami perubahan selama masa penyimpanan; gula menjadi lebih berwarna coklat. Kinetika reaksi dengan metode Arrhenius digunakan untuk menentukan laju perubahan warna gula tebu cetak dengan penambahan bubuk kayu manis (0,255%) dan tanpa penambahan bubuk kayu manis (0%, kontrol). Gula merah tebu cetak disimpan pada tiga suhu berbeda: 7°C, 27°C, dan 45°C selama periode 30 hari, dengan pengamatan  setiap tiga hari. Hasil analisis kinetika warna gula tebu cetak menunjukkan nilai laju penurunan (k) sebesar         0,1512; 0,1815 dan 0,2177 berturut-turut pada suhu 7°C, 27°C, dan 45°C untuk parameter light. Sementara itu, nilai laju penurunan (k) sebesar         0,7861; 0,8147 dan 0,9747 berturut-turut pada suhu 7°C, 27°C, dan 45°C untuk parameter hue. Hasil penelitian ini menemukan bahwa kualitas gula merah tebu cetak yang ditambahkan bubuk kayu manis berdasarkan parameter warna lebih cepat menurun dibandingkan gula merah tebu cetak kontrol. Hasil ini juga menunjukkan bahwa suhu penyimpanan 7°C memiliki laju penurunan warna gula merah tebu cetak yang lebih lambat dibandingkan dengan suhu 27°C dan 45°C. Persamaan penurunan mutu warna (light) gula merah tebu cetak pada perlakuan  kontrol yaitu k = 28,7489 e^((-407.74)1/T)) dan pada perlakuan gula merah tebu cetak kayu manis yaitu k = 1,9971 e^((-719.54)1/T)). Selanjutnya persamaan penurunan mutu warna (hue) gula merah tebu cetak pada perlakuan kontrol yaitu k = 1,1638 e^((-1276.1)1/T)) dan pada perlakuan gula merah tebu cetak kayu manis yaitu k = 3,3026 e^((-405.54)1/T)).
