Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh ukuran bongkahan batu kapur yang digunakan pada pengeringan absorpsi terhadap laju pengeringan fillet ikan patin. Tiga macam ukuran bongkahan kapur api, yaitu 100 g per bongkah atau dengan luas permukaan 8.65 cm2/kg (U1), 50 g per bongkah atau dengan luas permukaan 10.40 cm2/kg (U2), dan 25 g per bongkah atau memiliki luas permukaan 13.09 cm2/kg (U3), ditempatkan pada bagian bawah lemari pengering dan dipisahkan dengan kawat kasa dari fillet ikan patin yang ditempatkan di rak bagian atas,.perbandingan kapur: ikan (5:1). Untuk mencapai kadar air fillet ikan patin 12% basis basah, dibutuhkan waktu masing-masing selama 46, 38, dan 30 jam untuk luas permukaan bongkahan kapur 8.65, 10.40, dan 13.09 cm2/kg. Pengeringan fillet ikan patin terbagi dalam 4 periode, yaitu periode transisi (kondisioning), periode cepat (pengeringan air bebas), periode lambat (pengeringan air terikat tersier) dan periode sangat lambat (pengeringan air terikat sekunder). Pada batu kapur ukuran besar, proses kondisioning dan periode pengeringan air bebas cenderung lebih cepat tetapi setelah memasuki periode pengeringan air terikat, laju pengeringannya akan sangat lambat dibandingkan dengan penggunaan ukuran bongkahan yang lebih kecil.

Abstract

The presence of Eschericia coli (E.Coli) bacteria is one indicator of food contamination that can cause food-borne diseases. Fresh vegetables have nutritional advantages because they are consumed raw so that the nutrients contained in them are not denatured or changed. Types of vegetables that are usually consumed fresh have the potential to be detrimental to health because they are susceptible to microbial contamination. This study aims to review the sanitation hygiene of traders and determine the content of E.Coli bacteria in cabbage vegetables from fried catfish traders in one of the sub-districts in the city of Pekanbaru. The type of research used is survey and laboratory analysis. Technique sampling in this study is total sampling technique with a sample of 10 fried catfish traders. The results showed that hygiene and sanitation were still low in all traders. All traders do not use running water for washing vegetables and cutlery, and vegetables are not stored in closed containers. The results of bacterial analysis, it was found that 6 samples of fresh vegetables cabbage fried catfish contained E.Coli and the rest did not contain E.Coli bacteria. It can be concluded that the application of food sanitation hygiene by food handlers at several fried catfish traders in Pekanbaru City is in the poor category, because from 10 samples of cabbage vegetables, E.coli was found in 6 samples of cabbage vegetables.

Abstract

Inggu leaf (Ruta angustifolia (L.) is one of the medicinal plants that is widely used by Indonesian people as traditional medicine for various diseases. One of the properties of the inggu plant can be used to treat fever, toothache, heartburn and ulcers. Toxicity testing ethanol extract of guinea leaf using a completely randomized design (CRD) with 7 treatments with stratified doses of 500, 1000, 2000, 4000, 8000, 16,000 mg/kg BW and control. Parameters observed after administration of the extract were diarrhea, changes in breathing, changes in aggressive behavior and decreased movement activity. Liver and kidney organs were taken to determine the organ weight ratio. The results showed that the ethanol extract of inggu leaves with graded doses up to a dose of 16,000 mg/kg BW in experimental animals did not cause death, which was included in the practically non-toxic category. Administration of ethanol extract of guinea leaves at a dose of 500 mg/kg BW to 16,000 mg/kg BW caused a decrease in locomotion activity in experimental animals during the 4-hour observation time. The ratio of organ weight of mice from the test results of the ratio of liver, right kidney and left kidney of mice was not different from that of control animals.

Abstract

Palm kernel oil is considered a special oil since it contains medium chain tryglicerides (MCT), especially lauric acid that is easily digested and has a special character as cocoa butter substitutes (CBS). Palm kernel oil fractionation will produce a solid fraction (stearin) and a liquid fraction (olein) with specific characteristics (specialty fat) that the physico-chemical properties are highly dependent on the cooling treatment applied. In this research, 3 kinds of crystallization temperatures (18.0 oC, 19.0 oC, dan 20.0 oC) in various cooling rates and duration of the crystallization process, were examined for its effect on the crystal-forming rate of palm kernel oil and distribution changes of MCT content of fraction resulted. All tracks recorded during the cooling process had to be calculated to predict the crystal-forming rate in the crystallization process. In all cooling treatments, the amount of olein fraction produced decreased and the stearin fraction increased which was equal to the duration of the crystallization process. The setting of crystallization temperature at 18.0 oC produced a stearin forming rate higher than at temperatures of 19.0 and 20.0 oC. Forming rate of stearin (crystal) was contrary to the crystallization temperature and duration of the cooling period but not being affected by initial cooling temperature, initial cooling rate, duration of the cooling process to reach crystallization temperature, and average rate of oil cooling. Percentage of oil crystal-forming at 3 crystallization temperature equals to logarithmic of crystallization duration. The lower the crystallization temperature, the higher the rate of oil crystallization forming. As the increase of stearin produced during crystallization, MCT content was decreasing, but for olein, as the decreasing it during the crystallization period, the distribution of MCT content tends to increase.

Abstract

Purple yam starch-based edible film experienced high water vapor transmission rate. The use of composite starch using addition of modified starch of smaller size particles may decrease the rate. This study aimed to obtain starch concentrations that produced smallest size of modified starch, to produce composite starch for edible films and to determine the characteristics of edible films made out of native starch and edible films from composite starch (mixture of native starch and modified starch with the smallest size). This research was conducted in 2 stages: modification of purple yam starch by precipitation method and production of edible films from native starch and composite starch. This study was designed to produce modified starch using 5 levels of starch concentration (0,2%, 0,4%, 0,6%, 0,8%, and 1%) and 2 repetitions. The results showed that the treatment of 0,8% starch concentration produced the smallest particle size of starch (3,211 x 10,340 µm) up to (20,876 x 25,437 µm) with starch yield of 76,25%. Edible films made out composite starch have different characteristics than native starch alone. Edible films from composite starch produced higher thickness values ​​of 0.161 ± 0.007 mm, lower solubility 32,080 ± 4,671%, lower transparency of 10.644 ± 0.357% / mm and lower water vapor transmission rate (WVTR) of 24,701 ± 7,05 g / m2. hour and higher compressive strength 356,87 ± 7,38 gF than native starch edible films.
