Abstract

Psettodes erumei yang dikenal di Indonesia sebagai ikan sebelah memiliki sumber protein yang tinggi, namun seratnya terbatas. Moringa oleifera Lam adalah tanaman yang kaya serat pangan. Tujuan dari penelitian ini adalah untuk mengeksplorasi potensi ikan sebelah dalam bakso dengan perlakuan dan tanpa perlakuan tambahan Moringa oleifera Lam serta korelasi fisikokimia dengan perlakuan bakso ikan. Perlakuan yang dilakukan yaitu bakso ikan tanpa tambahan daun kelor dan tambahan daun kelor kukus 10%. Hubungan korelasi antara parameter-parameter fisikokimia antar perlakuan bakso ikan dianalisa dengan menggunakan principal component analysis (PCA) dan hierarchical clustering analysis (HCA). Hasil penelitian menunjukkan ikan sebelah segar berbobot 737,32 ± 257,39 g dan memiliki kadar air 78,69 ± 0,13% bb, protein 83,95 ± 7,49 % bk, serta lemak 2,49 ± 0,13% bk. Kadar air bakso ikan (79,32 ± 0,24%) lebih tinggi dibandingkan bakso ikan daun kelor 10 % (78,72 ± 0,24%), meskipun kadar protein keduanya tidak berbeda nyata (tanpa daun kelor 54,96 ± 0,74% dan daun kelor 55,28 ± 1,62%). Lightness bakso ikan daun kelor 10% (43,42 ± 0,30) paling rendah dan cenderung kehijauan. Gumminess dan chewiness dari ikan sebelah turun setelah dibuat menjadi bakso ikan, dan bakso ikan daun kelor 10% memiliki nilai paling rendah (gumminess 1672,31 ± 21,72 dan chewiness 1427,67 ± 58,77). Panelis lebih menyukai bakso ikan tanpa tambahan daun kelor. PCA menunjukkan bahwa kadar air, abu, yellowness, dan kekenyalan berkorelasi positif dari dua perlakuan bakso, namun berkorelasi negatif dengan kadar protein. HCA mempresentasikan adanya korelasi positif antara perlakuan bakso pada tekstur, protein, dan lemak.

Abstract

Coffee is a superior plantation commodity playing an important role in Indonesian economic growth, as a contributor to income and provider of employment. The handling process of coffee, particularly at roasting stage, has a significant impact on the quality of the final product. The Research Center for Appropriate Technology, National Research and Innovation Agency, has developed fluid-type roasting machine with a capacity of 750 grams (g) and fueled by LPG (liquefied petroleum gas). Therefore, this research aimed to determine the characteristics of robusta roasted coffee through performance tests of fluid-type roasting machine. Performance tests were carried out to determine the static characteristics of temperature sensor and ensure accurate provision as well as consistent readings in effectively controlling roasting process. Some of the characteristics that were determined included moisture content by thermogravimetric method, color, texture, caffeine, and microscopic analysis. The results showed that fluid-type roasting machine had a high-temperature sensor accuracy of 1.3% and repeatability of 0.69. The physical and chemical analysis showed that roasting temperature significantly affected the characteristics of roasted coffee beans. Additionally, higher temperature caused an increase in cracking of coffee beans, ash content, texture, caffeine content, and darker color, along with lower moisture content.
