Abstract

Cooking oil was one of the basic needs which consumed by the whole of Indonesian society. The high price of palm cooking oil and the lack of knowledge caused the repeated using of palm cooking oil which is harmful to health. The objective was to determine the physicochemical changes of used palm oil (Jelantah) on chicken frying. This research was using purposive sampling method. The experimental design used completely randomized design with one factor of frying frequency which were 0, 3, 7 and 10 times. Statistical analysis showed that the physicochemical tests (color analysis, peroxide value, acid value and moisture content) in each test was significant or significantly different, from the linear regression predicted that the frying frequencies which were used in fried chicken vendors were 16-54 times. In addition, it can be seen the characteristic qualities of used palm oil on chicken frying namely: color analysis L from 39.40% to 46.49%, a from 5.80% to 9.26%, b from 16,57% to 22.82%; peroxide value from 1.599 meq/kg to5.623 meq/kg; acid value from 0.076% to 0.153%; and water content from 0.021% to 0.267%. The physicochemical tests of used palm oil sample from fried chicken vendors namely: color analysis at L of 27.11%, a of 9.63%, b of 18.02%; peroxide value of 10.07 meq / Kg; acid value 0.434%; and water content of 0.166%.

Abstract

African catfish flour can be used for making pempek from premix flour. The objective was to study the effect of the catfish flour and compare tapioca and wheat flour to the texture and hedonic profiles of pempek lenjer from premix flour. The methods consisted of making catfish flour and pempek from premix flour. The treatments were catfish flours of 15%, 20%, and 25% and a comparison of tapioca and wheat flours of 1:1, 2:1, and 3:1, respectively. Analysis on catfish flour was yield and proximate characteristics, as well as analysis on pempek lenjer, were texture profiles of hardness, springiness, and stickiness, and hedonic profiles of color, aroma, taste, and springiness texture. A complete two-factor random design and Duncan’s post hoc analysis were used in the research. The results showed that catfish flour has a yield of 20%, moisture of 6,6%, ash of 1,54%, protein of 50,94%, fat of 16,75%, and carbohydrate of 24,17%. In addition, the more the catfish flour and the less the tapioca used led to the lower the hardness and the higher the springiness of pempek lenjer. However, it did not significantly affect the stickiness. The hedonic analysis showed that this pempek has a high preference value on all parameters. The texture profiles and hedonic test produced a combination of catfish flour of 20% and a comparison of tapioca and wheat flour of 2:1 as the chosen product in this research.

Abstract

Pempek merupakan salah satu jenis makanan tradisional masyarakat Sumatera Selatan dengan bahan utama daging ikan dan tepung tapioka serta ditambahkan air dan garam. Penelitian ini bertujuan untuk mempelajari pengaruh penambahan bahan lokal tepung talas Bogor dan penggunaan ikan lele dumbo terhadap profil tekstur dan kesukaan pempek lenjer serta kadar protein dan seratnya. Metode penelitian yang digunakan meliputi proses pemfilletan daging ikan lele, pembuatan adonan dengan campuran tepung tapioka dan talas, pembentukan pempek lenjer, dan perebusan. Perlakuan yang digunakan adalah perbandingan tepung tapioka dan tepung talas Bogor sebesar 100g:0g, 85g:15g, dan 70g:30g serta penggunaan daging ikan lele dumbo sebanyak 90g, 100g, dan 110g. Pempek yang telah dihasilkan kemudian diuji profil tekstur yang meliputi kekerasan, kekenyalan, dan kelengketan serta uji hedonik yang meliputi warna, aroma, rasa, dan tekstur kekenyalan. Hasil menunjukkan bahwa penggunaan ikan lele dumbo dan tepung talas Bogor yang lebih banyak menyebabkan kecenderungan semakin menurunnya tingkat kekerasan dan meningkatnya tingkat kekenyalan pempek lenjer yang dihasilkan serta tidak berpengaruh secara nyata terhadap tingkat kelengketan. Uji hedonik menunjukkan bahwa penambahan tepung talas dan ikan lele cenderung memiliki nilai kesukaan yang masih rendah terhadap parameter aroma, rasa, dan tekstur kekenyalan walaupun nilai kesukaan terhadap parameter warna cenderung memiliki nilai kesukaan yang lebih tinggi. Selain itu, uji hedonik menghasilkan kombinasi perlakuan perbandingan tepung tapioka dan talas 85g:15g dan ikan lele sebanyak 100 g sebagai perlakuan terpilih dalam penelitian ini. Pempek terpilih memiliki kadar protein dan serat pangan sebesar, berturut-turut, 7,06% dan 2,16%.

Abstract

The Roselle petals contain anthocyanin pigment which functions as an antioxidant and a natural food colorant. The objective of this research was to study the effect of three enzymes: pectinase, cellulase, and glucoamylase, on the quality of the extract of the Roselle petals. The fresh and dried Roselle petals were extracted using distilled water in a ratio of 1:4 and divided into five parts, in which each part was added by pectinase (P) of 1000ppm; pectinase and cellulase (PC) of 500:500ppm; pectinase and glucoamylase (PG) of 500:500ppm; and pectinase, cellulase and glucoamylase (PCG) of 333:333:333ppm, and without enzyme (TE) as a control. Furthermore, 1% of citric acid was added to all treatments. Determination of the chosen treatment used was based on residue extract, anthocyanin analysis, and the pH value. The results showed that fresh Rosella extract with PC has a yield value of 7.60% and it was not significantly different from the extract with PCG which yielded 7.37%.  Dried Rosella extract with PCG had the highest yield of 22.10% compared to the control (without enzyme) of 12.96%. However, the PCG addition generated a sticky product. Both fresh and dried Roselle extracts with PC contained the highest anthocyanin content of 156.64±1.30mgL-1 and 35.09±0.04 mgL-1, respectively. The pH values of fresh and dried Roselle extracts were 2.65 and 2.24, respectively. This research showed that the treatment of fresh and dried Roselle petals with the addition of  P, PC, or PCG increased the extraction yield value. Additionally, these enzymes could also increase the anthocyanin content of the extracts.

Abstract

Background: The X’s bakery industry makes banana chiffon using fresh banana fruit as a raw material; however, fresh bananas were prone to rot. Research purposes: to apply overripe banana flour in making chiffon and study the characteristic differences with fresh banana chiffon. Method: This research consisted of making overripe banana flour using foam mat drying and making banana chiffon. The chiffon cake was made by adding 20g, 40g, and 60g banana flour (150g flour base) and control of 50g fresh ripe bananas. The yield, color, repose angle, and moisture content of overripe banana flour were analyzed, including specific volume, chiffon color, chiffon swelling, texture profile, and moisture content in chiffon cake. A complete one-factor random design with Dunnet’s analysis was used. Results and Discussion: The results showed that overripe banana flour has yellowish color with a yield of 26.23±0.45%, a repose angle of 27.44±0.92, and a moisture content of 7.97±0.43% (wet base). Statistical analysis showed that chiffon of overripe banana flour did not differ significantly at 5% from than chiffon of fresh bananas on several parameters. They were the specific volume of the dough and moisture content and swelling, hardness, adhesiveness, elasticity, and chewing power. In addition, the chiffon’s crumb section of banana flour has a lower brightness compared to fresh banana chiffon, where the top, middle, and side crusts were not significantly different. Conclusion: These results indicated that the use of banana flour could replace fresh bananas in chiffon cake.

Abstract

Rice husk has high silica (SiO2) content and can be used as the primary material for making nano-silica. One of the methods for synthesizing nano-silica was the hydrothermal method. The objective of this study was to synthesize nano-silica from rice husks by observing the effect of temperature in the hydrothermal process on the structure, electrical and particle properties of nano-silica. The hydrothermal process temperature was 150, 200, and 250 °C for 4 hours. The results showed that all nano-silicas were in the amorphous phase. The particle size was in the range of 0.16-13.49 nm with more uniform size distribution on nano-silicas of 200 °C and 250 °C than nano-silica at 150 °C. These three nano-silicas were included in the semiconductor category by increasing temperature and frequency. In addition, these treatment variations resulted 200 °C for 4 hours and pressure of 2 atm as the optimum treatment for manufacturing nano-silica of rice husk ash. This nano-silica could be used as semiconductor material for electronic industry.

Abstract

Flour modifications can be conducted to expand its utilization into processed products. This research aimed to study the effect of physical and biological modification on the physicochemical properties of canistel (Pouteria campechiana) flour. The research method included making canistel flour unmodified (native), physical modification using heat moisture treatment (HMT) method, and biological modification by fermentation. Physical properties analysis included color and morphology of starch granules, while chemical analysis included water content, total sugar content, starch content, amylose content, and amylopectin content. The data were analyzed statistically using One Way ANOVA and continued with the Duncan post hoc test. Statistical analysis showed that modification of canistel flour could decrease brightness and increase a value and decrease b value. Native, HMT-modified, and fermented-modified canistel flour had colors of incarnation, rose pink, and fresh plaster, respectively. In addition, the fermented modified canistel flour tends to have higher total sugar content, although the HMT modified flour tends to decrease compared to the native canistel flour. Modified canistel flour tends to have lower starch, amylose, and amylopectin content than native flour. Morphologically, modifications to canistel flour have no effect on flour morphology. Keywords: fermentation, heat moisture treatment, modified flour, Pouteria campechiana

Abstract

Study of crystal structure of ceramic materials was one of chapters in Solid State Physics for undergraduate curriculum in Indonesia. Tetrahedron crystal structure was interesting to be reviewed in order to provide an understanding to the students for analyzing the ionic radius ratio of small and large atoms (r/R) as molecul composer in ceramic materials. Study of ratio on tetrahedron crystal structure (coordination number of 4) was more difficult than octahedron (coordination number of 6) as well as cubic structures (coordination number of 8), because on tetrahedron, small atoms bound four large ionic atoms which were located in three-dimensional space that causing the wedge angle (ɵ) became not perpendicular to each other. A review of tetrahedron crystal structure using mathematical physics analysis of Menelaus theorem resulted r/R ratio of 0.225 with wedge angle of 109.5o. Key words: crystal structure, ionic radius, Menelaus theorem, ratio of r/R, tetrahedron.
