Abstract

Banana flour is one of the semi-finished products which processed aims to maintain shelf life, provide goods for diver food products, facilitate packaging and transportation. This research aimed to determine and compare the physical characteristics of flour from three banana species, i.e., Kepok (Musa acuminata x balbisiana), Talas (Musa acuminata Colla var. Talas), and Cavendish (Musa acuminata Colla var. Cavendish). This research is a single factor experiment arranged in a completely randomized design with three (banana species) treatments and five replications. Data were analyzed by ANOVA except for wettability data, and gelatinization profile is processed using the Kruskal-Wallis test. The experimental parameters were swelling power, starch solubility, bulk density, water absorption capacity, oil absorption, and color. The results showed that swelling power and oil absorption of the banana flour from the three banana species are not significantly different (p > 0.05) but significantly different (p < 0.05) for solubility, bulk density, wettability, water absorption capacity, and color. Gelatinization temperature for Kepok, Talas, and Cavendish banana flour was 79.45°C, 81.45°C, and 78.20°C, respectively. In this research, we found that the physical properties of Talas banana flour are in between the physical properties of Kepok and Cavendish banana flour.

Abstract

This study aimed to determine the patchouli oil (PO) business in the province of East Kalimantan based on data on the yield and quality of PO produced from several PO production centers in East Kalimantan. Bangun Rejo Village in Kutai Kartanegara Regency, Sepaku I Village and Argo Mulyo Village in Penajam Paser Utara Regency were selected as samples in this study. PO extraction from plant samples from each village was carried out using a laboratory-scale wet distillation method (3 kg leaves, branches) per batch. Each batch was carried out with six replications using different samples. The sample of PO produced by farmers was used as a control. The results showed that the yield of PO from the three villages reached 1.25-1.76%, while the quality of the oil showed an acid number of 2.407-4.747%, ester number 11.843-16.768%, PO content 33.670-43.693%, iron content 1.096-8.538 mg/kg, density 0.614-0.822 g/cm3, refractive index 1.509 nD20 and light-yellow to yellow. PO produced by farmers has an acid number of 6.311-11.920%, ester number 16.269-19.822%, ethanol solubility 1:5-1:9, patchouli alcohol content 31.96-40.89%, iron content 0.460-1.105 mg/kg, density 0.946-1,509 g/cm3, refractive index 1.508-1.510 nD20 and yellow to dark yellow in colour. Techno-economic analysis (using laboratory-scale extraction yield data) shows that PO refining business in the two villages is feasible to be carried out with B/C values of 3.62 and 6.37 for Sepaku I Village and Bangun Rejo Village. Still, it is not feasible for Argo Mulyo (B/C value of 0.842)

Abstract

Minuman herbal menjadi semakin penting setelah senyawa-senyawa metabolitnya diperoleh fungsinya bagi kesehatan. Penelitian ini bertujuan untuk mengetahui pengaruh metode pengeringan terhadap profil FTIR, sifat fisiko kimia, antioksidan dan sensori minuman herbal tiwai. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) Non Faktorial dengan 3 perlakuan yaitu pengeringan dengan oven, matahari dan pengeringan dengan sangrai. Data dianalisis sidik ragam dan uji lanjut BNT (taraf 5 %). Hasil dari FTIR serapan ikatan O-H diperoleh pada bilangan gelombang 3261-3270 cm-1, serapan ikatan O-H merupakan pembentuk senyawa fenol/flavonoid yang merupakan antioksidan pangan.  Metode pengeringan minuman herbal tiwai berpengaruh tidak nyata terhadap sifat sensoris hedonik dan mutu hedonik warna, aroma maupun rasa. Pembentukan warna minuman herbal tiwai paling cepat dengan metode pengeringan oven yaitu 3.67 menit. Intensitas warna tertinggi terdapat pada pengeringan sangrai dengan nilai 0.563. Aktivitas antioksidan tertinggi juga dihasilkan pada pengeringan sangrai 185,24 ppm.
