The study objective was to determine the shelf life of edible coating packaged of durian lempok. The experimental method used in this study was Factorial Randomized Block Design consisting of three factors. These factors were tapioca starch, stearate acid, and CMC. The edible coating solution was applied in to durian lempok by using dip method. The result showed that edible coating packaged of durian lempok could increase the durian lempok shelf life by 67 percent than durian lempok without edible coating. The edible coating was capable of decreasing the durian lempok weight loss by magnitude of 36.38% during storage, decreasing the peroxide number by magnitude of 33.33%, decreasing the water content by magnitude of 7.54%, and suppressing the microbial growth by the amount of 31.20%, respectively. Visual change of non-coating lempok had occurred on the day of 19th, which was indicated by greyish-white colour change due to certain type of mold on lempok surface, while the similar change happened at day of 31th (T2A3C3 treatment). Key words : Tapioca, CMC, stearate acid and edible coating.

The purpose of this research was to study the effect of temperature and time of vulcanization in rubber sole compound manufacturing by utilizing palm shell charcoal as filler. The research was carried out at Industrial Research and Standardization Laboratory Palembang on May to November 2012. Experimental design used in this study was factorial completely randomized design (CRD). Two factors were investigated, namely temperature (designed as T with the following three levels: 130, 140 and 150 °C) and vulcanization time (designed as W with the following levels, 10, 12 and 14 minutes). The observed physical parameters were according to SNI 0778: 2009, including tensile strength, elongation at break, hardness and tear strength.

This research aims to determine the gelatinization profiles of pempek lenjer dough from several formulas, with comparising fish with tapioca flour treatment. During the heating occured an increase in viscosity caused by the swelling of the irreversible starch granules in the water caused by the kinetic energy of water molecules which is stronger than the attraction of starch molecules so that the water could get into the starch granules. Gelatinization profile result showed that the higher the addition of tapioca flour on the pempek dough the lower the initial gelatinization temperature (63°C), the lower the maximum viscosity (100 BU) is more compact the gel, paste stability was relatively low (41 BU) and the higher the reverse viscosity (31 BU), the development of the granules became larger, but the greater the the possibility of retrogradation.Keywords: dough, formulation, gelatinization, amilography properties, pempekAbstrakPenelitian ini bertujuan untuk mengetahui profil gelatinisasi adonan pempek lenjer dari beberapa formula, dengan perlakuan perbandingan ikan dengan tepung tapioka. Selama pemanasan terjadi peningkatan viskositas yang disebabkan oleh pembengkakan granula pati yang irreversible dalam air, karena energi kinetik molekul air lebih kuat dari daya tarik molekul pati sehingga air dapat masuk ke dalam granula pati. Hasil profil gelatinisasi menunjukkan bahwa semakin tinggi penambahan tepung tapioka pada adonan pempek maka suhu awal gelatinisasi semakin rendah (63°C), viskositas maksimum semakin rendah (100 BU) gel lebih kompak, stabilitas pasta relatif rendah (41 BU) dan viskositas balik semakin tinggi (31 BU) pengembangan granula lebih besar, tetapi kemungkinan retrogradasi semakin besar.Kata kunci: adonan, formula, gelatinisasi, sifat amilografi, pempek

AbstractThe objectives of this research were to study the effect of fish and flour formulation as well as centre point temperature on the thermal diffusivity and shelf life of pempek lenjer. The parameters observed were the temperature of pempek at several position: i.e. (r0) = 0 cm, r1 = 1 cm, r2 = 2 cm, cooking time, change of textural value, total volatile nitrogen and total microbes of pempek during storage. Data temperaturedistribution was analyzed by using diffusivity at center point model, and random diffusivity models through computer program of Engineering Equation Solver (EES) Ver 8.91. The shelf life data was analyzed by usinglinear regression to determine the relationship between storage time and the measured variables which was followed by calculating using Arrhenius method to compare the decrease of pempek lenjer quality. The results showed that thermal diffusivity coefficient of pempek lenjer for formula 1 was in the range of 0.321 to 1.515 .10-7 m2/s, for formula 2 was in the range of 0.297 to 1.389.10-7 m2/s, for formula 3 was in the rangeof 0.378 to 1.471 . 10-7 m2/s and for formula 4 was in the range of 0.2778 to 1.620.10-7 m2/s.The research results showedthat longerstorage time results in lower values of texture, but produced higher value oftotal volatile nitrogen and total microbes.

Background. Dental and gum disease is a health problem faced by many countries around the world. Dental and gum diseases begin with the formation of plaque on the tooth surface, as a result of the activities of bacteria in the oral cavity. Elimination of the bacteria as caries causal has been done in many ways, one of them by using plant extracts which have anticariogenic activities, such as gambir (Uncaria Gambir [Roxb.]). The aim of this study was to determine the effect of chewing candy containing gambir on the decrease of bacterial colonies and dental plaque formation. Methods. A Pretest-Posttest Control Group Design had been conducted in SMPN 17 of Junior High School in Palembang and Province’s Health Laboratory of South Sumatera, Indonesia. The population consisted of 50 participants, divided into 5 groups. Each group was chewing with 5%, 7.5%, 10% extract-gambir candies, no chewing candies, and chewing sucrose’s candies. Data were analyzed by using SPSS vers 22. Result. The results showed that all candies containing gambir extract were able to reduce the formation of dental plaque and to decrease the bacterial colonies in saliva. The best effect of this study was 10% extract-gambir candies. Conclusion. It can be concluded that extract-gambir candies were effective in the decline of dental plaque formation and bacterial colonies.
