Abstract

Kolang kaling merupakan salah satu produk dari tanaman aren. Peningkatan nilai ekonomi usaha pengolahan kolang kaling dapat dilakukan melalui diversifikasi produk kolang kaling dalam bentuk permen jelly kolang kaling. Penambahan kolang kaling pada formulasi pembuatan permen jelly kolang kaling merupakan salah satu usaha untuk mengurangi penggunaan senyawa pengental yang selama ini digunakan dalam proses produksi permen jelly. Kajian kelayakan usaha produksi permen jelly kolang kaling memiliki peran stategis dalam pengembangan usaha diversifikasi produk kolang kaling. Hasil perhitungan analisa finansial menunjukkan bahwa dari perhitungan laba/rugi rencana investasi usaha akan menghasilkan laba bersih sebesar Rp 592.035,00/bulan. Hasil perhitungan menunjukkan bahwa usaha permen jelly kolang kaling akan mencapai titik impas (BEP) apabila memproduksi dan menjual permen jelly kolang kaling sebanyak 41,7 kemasan atau senilai Rp 687.925 Kata kunci: permen jelly, kolang kaling, analisis financial

Abstract

Negara Indonesia memiliki banyak biomass sebagai salah satu sumber energi. Satu diantaranya limbah kulit nanas memiliki kandungan selulosa cukup besar yang bisa dimanfaatkan sebagai sumber bahan baku energi terbarukan. Akan tetapi adanyan lignin dalam kulit nanas menjadi penghambat dalam proses degradasi sel. Sehingga perlu dilakukan penelitian mengenai proses optimasi selulosa limba kulit nanas dengan dengan metode delignifikasi MAE (microwave asissted extraction). Metode MAE memanfaatkan pancaran gelombang mikiro terhadap bahan polar sehingga terjadi interaksi antar molekul atau rotasi dipol yang menghasilkan panas sehingga dapat membantu memecah struktur bahan yang komplek menjadi struktur yang lebih sederhana. Dari hasil penelitian yang telah dilakukan dengan memvariaskan suhu operasi pada 70oC, 80oC dan 90oC didapatkan hasil bahwa kelarutan lignin meningkat seiring dengan kenaikan suhu operasi. Sampel kontrol yang digunakan sebagai pembanding memperoleh kelarutan lignin dan selulosa sebesar 2,68% dan 17,39% dari berat sampel. Sedangkan pada sampel yang dilakukan proses delignifikasi MAE mampu menaikan kelarutan lignin dan selulosa mencapai 9,04% dan 29,42% dari berat sampel pada suhu operasi 90oC, waktu 20 menit dan rasio 1:20 (b/v) yang menjadi kondisi optimum operasi delignifikasi MAE dengan variabel suhu. Sedangkan pada suhu 700C dan 800C secara berurutan mampu melarutkan  28.1955 %, 28.1389 % selulosa dan 7.4248 %, 7.3909 lignin.

Abstract

Amberlyst-15, a strong acidic ion-exchange resin, has showed as a potential and an effective catalyst for the glycerolysis process of urea to glycerol carbonate. In this work, the kinetic model of the urea glycerolysis over Amberlyst-15 catalyst was investigated. The kinetic model was developed by considering simultaneous steps of urea dissolution in glycerol, mass transfer of urea and glycerol from the bulk of the liquid into the outer part of the catalyst, diffusion of urea and glycerol into the inner part of the particle through the catalyst pores, and irreversible second order reaction of urea and glycerol on the active sites. The irreversibility of second order reaction of urea glycerolysis was validated and proven. The proposed kinetic model was simulated and validated with the experimental data. The kinetic studies show that mechanism proposed works well. Furthermore, the activation energy was found to be 145.58 kJ.mol−1 and the collision factor was in 8.00×1010 (m3)2.kg−1.mol−1.s−1. The simulation result shows that the predicted liquid temperatures were close to the experimental temperature data. It also gave glycerol concentration profile inside the catalyst particle as a function of glycerolysis time and position. Copyright © 2021 by Authors, Published by BCREC Group.

Abstract

Apocarotenoids are the degradation product of the enzymatic and or non enzymatic cleavage of carotenoids. Apocarotenoids are present in plants, fungi, bacteria and a certain animal species. There have been large numbers of apocaretonoids identified as the consequence of the great variety of naturally occurring carotenoids. Apocarotenoids can be found as volatile, semi-volatile or non-volatile compounds based on their chemical structures, while based on the number of the carbon atoms contained in their structure, apocarotenoids is classify into triporoids, cyclofarnesoids and methylhexanoids. Bibliometric analysis performed on publication having “apocarotenoids” keywords informs that crocin, pirocrocin, saffron and crocus sativus nodules appear in the overlay visualization. The appearance is attributed to the great potential application and commercialization of crocin which is originated from saffron. The bibliometric analysis also shows that there is food additive nodule appear which imply the strong correlation and potential application of apocarotenoids as food additive. The potential utilization and the commercial production of apocarotenoids are challenged by the the genetic diversity as well as the high cost, time consuming and seasonal production of natural apocarotenoids isolation process. Chemical synthesis, engineering biosynthesis and bio-manufacturing using microbes provide a promising and economical alternative.
