Uwi memiliki kandungan pati cukup tinggi dengan ukuran granula pati cukup besar berada pada kisaran 25-45μm. Ukuran granula pati diketahui berpengaruh terhadap aplikasi pati dalam industri. Ukuran granula pati yang kecil lebih disukai karena memiliki rasio luas permukaan terhadap volume yang besar sehingga meningkatkan interaksinya dengan komponen lain dalam sistem pangan. Untuk mendapatkan granula pati yang berukuran lebih kecil dapat dilakukan modifikasi dengan menggunakan metode presipitasi. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi pati dan jenis pelarut terhadap sifat fisik pati uwi putih yang dimodifikasi menggunakan metode presipitasi serta untuk mendapatkan konsentrasi pati yang dapat menghasilkan pati modifikasi dengan ukuran paling kecil. Penelitian ini dilakukan dalam 2 tahap yaitu ekstraksi pati uwi, modifikasi pati uwi dengan metode presipitasi. Penelitian ini didesain menggunakan 3 taraf konsentrasi pati yaitu 1%, 3%, dan 5% dengan 2 jenis pelarut berbeda yaitu pelarut akuades dan pelarut campuran akuades dan etanol dengan perbandingan 1:1. Hasil penelitian menunjukkan bahwa pelarut akuades menghasilkan pati modifikasi dengan karakteristik terbaik dan konsentrasi pati pada taraf 3 % menghasilkan pati modifikasi dengan ukuran terkecil yaitu (3.848- 33.273 μm), rendemen tertinggi (87,11% ± 0,18), swelling Power sebesar 18,91 (65oC), dan 21,89 (85oC), Solubility sebesar 1,08% (65oC), dan 0,55% (85oC), Nilai daya serap air tertinggi (995%) dan daya serap minyak tertinggi (617,5%).

Pyrolysis is the one solution to recycle hydrocarbon-based waste material such as used lubricant and cooking oil. The aim of this research was to determine the effect of temperature and sample ratio on the liquid yields of a mixture of used lubricant and cooking oil. The semi batch reactor was used with a constant nitrogen flow rate of 5 mL/min. Three different ratios of sample mixture were applied in this experiment: 0.5:1, 1:1, and 1.5:1, and three different temperatures: 4000C, 4500C, and 5000C. The thermal pyrolysis of a mixture of used lubricant and cooking oil was deemed as the most effective pyrolysis to produce liquid fraction was obtained from reaction condition with the sample mixture ratio of 0.5:1 at 5000C. At this reaction condition, the liquid yield was 58.90% which consist of 64.12% were C1-C3 and 29.54% were C5-C15. Liquid fraction is predicted to increase as the temperature increase and the ratio of used lubricant to cooking oil decrease. When the ratio is increased , more gas fraction is produced.

Current petroleum energy sources have been starting to diminish along with the increasing a demand in industries and transportations. In the next few years Indonesia is predicted to experience a fuel crisis. One way to solve this problem is to find the alternative energy sources from renewable raw materials. This study was conducted to obtain alternative renewable energy sources through catalytic cracking of used cooking oil-derived methyl ester into biofuel using active charcoal catalyst. The active charcoal was made out of solid waste (shells) of the oil palm industry. Nickel solutions of varying concentrations (1%, 2%, 3%) ware impregnated into active charcoal to produce the Ni- charcoal catalyst. This catalyst was then used for catalytic cracking of methyl esters with variations in the reaction temperature of 400oC, 450oC and 500oC. The Methyl ester was produced from filtered used-cooking oil by transesterification method. SEM-EDX analysis showed that Nickel metal was successfully embedded into active charcoal where the highest concentration of Nickel (18.4%) was found at a impregnation treatment using 2% of Nickel solution. From the SEM image, it can also be seen that the catalyst produced unique pores. The gravimetric analysis of the catalytic cracking product showed that the highest fraction of oil liquid resulting from catalytic cracking at 400oC using Ni-charcoal catalyst impregnated with 3% Nickel solution.

The potency of yam starch (Dioscorea alata) as film-forming material together with the potency of chitosan and clove oil as antibacterial materials has led the authors to produce active bioplastics based on these materials. This research was performed to determine the effect of chitosan and clove oil on the physical, mechanical, and barrier properties of yam starch’s active bioplastics. The best bioplastics produced were further tested for their antimicrobiological properties. This study used a completely randomized design with five levels of chitosan concentration (1%, 1.2%, 1.4%, 1.6%, and 1.8%) and five levels of clove oil concentration (0.3%, 0.6%, 0.9%, 1.2%, and 1.5%). Each treatment was repeated four times. The results showed that the concentrations of chitosan and clove oil had a significant effect on the thickness and water vapor transmission rate of film but did not affect its solubility and compressive strength much. The use of 1% chitosan or 1.5% clove oil produced biofilms with the lowest water vapor transmission rate. Both plastics also exhibited strong antibacterial activity against Staphylococcus aureus with chitosan bioplastics having a larger inhibition zone than that of clove oil bioplastics.

Purple water yam flour modified by Lactobacillus plantarum fermentation may be used as an ingredient in flour-based functional food. The purpose of this research is to determine the effect of fermentation time on the functional properties of purple water yam flour modified using L. plantarum. This research used a randomized block design with six treatments: without fermentation (control) and 12, 24, 36, 48, and 60 h of fermentation. Results showed that lactic acid bacteria initially grow well with increasing viability over 48 h of fermentation. Growth and viability rates began to decrease as the organisms entered the declining or dying phase. Statistical analysis showed that fermentation time affects the solubility at 75 °C, chromatic color values L* and b*, and antioxidant activity of flour. Fermentation for 36 h produced the best modified purple water yam flour with an antioxidant activity of 69.82%, bulk density of 0.817 g/mL, water absorption capacity of 3.31 g/g, oil absorption capacity of 1.20 g/g, solubility of 0.45%, L* of 80.33, a* of 16.33, and b* of −5.33. The results indicate that purple water yam flour modified by L. plantarum fermentation for 36 h could be developed as a functional food ingredient.

The existed edible films made of water yam starch tend to have a low quality which is indicated by high WVTR value and low mechanical strength. Addition of modified starch can decrease the WVTR value and improve the mechanical properties. The purpose of this study is to obtain the ratio of starch paste volume to ethanol volume which produces modified water yam starch and to improve the quality of the edible film by adding modified water yam starch. This research was conducted in 2 stages, which are the modification of water yam starch using the precipitation method and the making of edible films using several levels of modified water yam starch concentration. The first stage of the study was designed to produce modified starch using the treatment of the ratio of starch paste volume to ethanol volume. There are 5 treatment ratios used, which were 1:5, 1:7.5, 1:10, 1:12.5, and 1:15. The results showed that the different ratios of starch paste volume to ethanol volume resulted in different sizes of modified starches. The ethanol volume ratio of 1:5 resulted in a granular starch with the most damage in its morphology, and the smallest particle size detected was 1.135x1.767 µ, with the yield of modified starch was 80.5%. The addition of modified water yam starch of as much as 20%, which was modified using a ratio of paste volume to ethanol volume of 1:5, succeeded in improving the quality of the edible film of water yam starch by reducing the value of the water vapor transmission rate and increasing the compressive compressive strength.
