Abstract

Tujuan penelitian ini adalah untuk mengetahui (1) penggunaan karbon aktif dari berbagai bahan alami dalam penjernihan air dan (2) penggunaan biji kelor dalam penjernihan air, dan (3) cara menganalisis logam berat dari hasil penjernihan air. Metode yang digunakan dalam penelitian ini yaitu metode telaah pustaka yang sistematis, atau biasa disebut dengan Systematic Literature Review (SLR) yang dimana hasilnya menggunakan database artikel online yaitu Google Schoolar. Hasil telaah dari artikel yang berkaitan dengan topik diperoleh bahwa penggunaan karbon aktif atau arang yang terbuat dari bahan alami seperti kayu kesambi, ampas tebu, tongkol jagung, kulit buah durian dan eceng gondok sangat efektif dalam penyerapan zat terlarut air, baik organik maupun anorganik dalam menghasilkan air yang jernih. Selain itu, penggunaan biji kelor juga sangat efektif sebagai biokoagulan dan bioflokulan dalam menurunkan pH, kesadahan, kekeruhan dan total padatan tersuspensi, sehingga memungkinkan munculnya rekomendasi bahwa air hasil penjernihan dengan menggunakan karbon aktif dari berbagai bahan alami dan serbuk biji kelor dapat dijadikan air minum.

Abstract

An analytical method was carried out to identify volatile compounds that play a role in the coffee aroma and their stability. Because it is unstable at high temperatures, the effect of the injection temperature on the GC/MS column on changes in compounds profile was observed. The aim of this research is also to develop analytical methods for coffee analysis using TPI-GC/MS method. Samples of Lemar Arabica coffee were taken from the Wonosantri Abadi plantation, Singosari, Malang, and roasted at 210°C. The roasted coffee was extracted using the soxhletation method and methanol as solvent. The compound profiles were analyzed using the GC/MS method with injection temperatures of 40°C, 140°C, and 240°C. The results showed that ketones, esters, furans, and thiazoles play a role in the aroma of coffee. The compounds present in roasted coffee injected at 40°C were less than those at injection temperatures of 140°C and 240°C based on the chromatograms. The profile of the compound at the injection temperature of 240°C is also more diverse than the others because the large injection temperature allows decomposition to occur so that there are many fractional compounds from the thermal decomposition. Toluene is the most stable compound because it appears at all three injection temperatures. Non-volatile caffeine compounds were also detected at an injection temperature of 240°C.

Abstract

The banana plant that is still underutilized compared to the fruit part is the heart of the banana. Even though the heart of the banana has many benefits and nutritional content that is good for health. Seeing the potential of the heart of the banana can improve public health, so food diversification efforts such as flour and substitutes for the basic ingredients of food to produce new forms of product innovation, so research was carried out to test its content, which aims to inform the public that the heart of the banana can be beneficial for health in processing into flour. This research was carried out in March-April 2022 at the Chemistry Education Laboratory of Nusa Cendana University, Kupang. There are four stages in this study, including 1) Manufacture of the heart of banana flour; 2) Proximate Test of the heart of banana flour; 3) Diversification of products based on the heart of banana flour, 4) Organoleptic test of products based on the heart of banana flour on 52 panelists. The results of research on the manufacture of banana heart flour are substituents of flour that have good nutritional content with relatively good character if used as a substitute for wheat flour because many parameters meet the quality requirements of wheat flour, namely the physical characteristics of banana heart flour meet the test requirements for shape. In contrast, the aroma, color, and taste in accordance with the characteristics of the nutritional content meet the moisture content proteins, fats, and carbohydrates. In contrast, the ash content does not complete because the mineral content in each ingredient is different and the manufacture of wheat flour. The result of the diversification of the products made, namely the Genital Widow Cake / Monde chips made from banana heart flour, are also included in the excellent category where the aroma, taste, and acceptance of the product are accepted in the community.
