Abstract

Selai merupakan produk makanan berupa pasta yang terbuat dari buah, sayuran atau umbi-umbian yang dihancurkan menjadi bubur dengan penambahan gula, asam, bahan pengental, serta bahan tambahan pangan yang diijinkan. Ubi ungu merupakan komoditas yang dapat dikembangkan menjadi selai. Substitusi bubur nanas dilakukan untuk meningkatkan cita rasa pada selai yang diproduksi. Tujuan pengujian ini yaitu untuk mengkaji pengaruh variasi substitusi bubur nanas terhadap karakteristik kimia selai. Metode yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dengan 3 kali ulangan. Perlakuan yang dilakukan yaitu substitusi bubur buah nanas yang terdiri dari P0 (0%), P1 (35%), P2 (40%) dan P3 (45%) dengan 3 kali pengulangan. Pengolahan data menggunakan ANOVA, yang dilanjutkan dengan Uji DNMRT taraf signifikan 5%. Hasil penelitian menunjukkan substitusi bubur buah nanas yang berbeda memberikan pengaruh yang nyata terhadap karakteristik kimia selai. Perlakuan terbaik dihasilkan dari sampel P3 dengan kandungan substitusi nanas sebesar 45% dengan karakteristik kadar air: 38,98±0,47d, pH: 4,29±0,01a, TPT: 8,00±0,10d%, TAT: 2,13±0,11d%, dan Vitamin C: 119,68±0,00d mg/100g.

Abstract

Aerva sanguinolenta leaves contain anthocyanis that can be utilized as a borax detector in food products. This study aimed to determine the charateristics of Aerva sanguinolenta leaf extract and evaluate its effectiveness as a natural color indicator for borax detection. The research employed a Completely Randomized Design (CRD) with four treatments of borax concentrations (0%, 1%, 2%, and 3%) with three replications. The paramaters observed included the yield and pH of the extract, as well as the reaction of the extract and the natural color indicator when exposed to varying borax concentration treatments. Data were analyzed using ANOVA and followed by DMRT at a 5% significance level. The result showed that the leaf extract yield was 79% with a pH of 4,93. The extract reacted positively to borax, producing varying color intensities across treatments. The natural color indicator reacted with borax and exhibitied significant differences (P<0,05) in red and yellow color parameters. The higher the borax concentration resulted in darker indicator color, indicating that natural color indicator from Aerva sanguinolenta leaves are effective for borax detection.

Abstract

This research examined the potential of essential oil–based bio-additives derived from citronella, clove, and patchouli to enhance the physicochemical properties, engine performance, and emission characteristics of Pertalite fuel. The study utilized Response Surface Methodology (RSM) with a Central Composite Design (CCD) to assess additive concentrations between 0.1 and 0.3 mL per liter of Pertalite. Findings indicated that these low-level additions did not significantly affect density, which remained similar to pure Pertalite. Likewise, power output and exhaust emissions (CO2 and O2) showed no notable improvements. Statistical evaluation using Design Expert® revealed all regression models were non-significant (p > 0.05), and optimization attempts failed to identify a valid optimum, with desirability values below 0.5. The minimal impact is attributed to the very low additive dosage, insufficient to influence atomization, combustion, or emission reduction. Additionally, gasoline’s non-polar nature limits sensitivity to parameters such as pH, while operational variations during engine testing (temperature, RPM, and load) may have masked minor effects. In summary, essential oil bio-additives at concentrations below 0.03% by volume are ineffective for measurable improvements. Future studies should investigate higher concentrations, purification of active compounds, improved blending techniques, and stricter engine testing protocols. The contribution of oxygenated compounds to combustion enhancement also merits further exploration.
