Abstract

Salah satu tanaman yang potensial dikembangkan di Propinsi Bengkulu adalah buah jeruk Rimau Gerga Lebong (RGL) dan jeruk Kalamansi. Tanaman buah jeruk Gerga Lebong dan jeruk Kalamansi, merupakan salah satu bahan baku industri pengolahan sirup buah. Limbah yang dihasilkan dari industri ini berupa kulit buah dan kulit+daging buah hasil pengepresan sari buah. Limbah tersebut berpotensi sebagai sumber pektin. Pektin adalah suatu komponen serat yang terdapat pada lapisan lamella tengah dan dinding sel primer pada tanaman. Senyawa-senyawa pektin juga berfungsi sebagai bahan perekat antra dinding sel yang satu dan lainnya (Winarno, 1991). Tujuan penelitian ini adalah untuk melakukan kajian terhadap rendemen dan mutu pektin yang dihasilkan dari limbah jeruk Gerga Lebong dan jeruk Kalamansi. Hasil penelitian menunjukan bahwa rendemen pektin dari limbah Jeruk kalamansi lebih besar dari limbah jeruk Gerga Lebong. Secara berturut-turut rendemen yanga dihasilkan adalah 15,3 % (kulit jeruk kalamansi), 7, 82 % (kulit+daging buah kalamansi), 1,5 % (kulit jeruk Gerga Lebong) dan 0,18 % (kulit+daging buah jeruk Gerga Lebong). Hasil analisa mutu terhadap variabel Galakturonat menunjukan bahwa nilai Galakturonat pada kulit jeruk Kalamansi mempunyai nilai tertinggi yaitu 93,51 %. Analisa terhadap derajat Esterifikasi menunjukan bahwa pektin hasil ekstraksi limbah jeruk Gerga Lebong dan jeruk Kalamansi tergolong pada pektin bermetoksil rendah, dengan nilai derajat esterifikasi pada kisaran 13,77-20,83.

Abstract

Fruits can suddenly loose its quality, thus it needs a good packaging material with a suitable permebiality, so that gas exchange inside the packaging normally take place through film packaging. The increasing of permeability on plastic film can be done by giving perforation or a whole on its surface. This research is intended to find out the rate gas exchange through film packaging. In packaging system with modified atmosphire. The result of this research shows that the use of perforation with micro size (50-200 µm) can increase the rate of gas transmission of plastic film toward O. Identification on packaging material which is used reveal that plastic permeability without perforation toward O2 is less than plastic permeability with 10 perforation. Gas equilibrium for 10 perforation packaging resulted on day 21 with gas concentration 0,001% (O2) and 0,000798 % (CO2). The approach by using mathemathic model is done to find out gas concentration inside the packaging during the storage. The model which is developed by Gonzales et al. (2008) nearly close to the result as the observation conducted.

Abstract

Penanganan pasca panen pisang ambon curup harus benar-benar diperhatikan, karena buah pisang Ambon Curup memiliki tekstur yang lembut dan mengalami proses pematangan yang cepat sehingga sangat mudah terserang infeksi dan penyakit pasca panen. Penelitian ini bertujuan untuk mendapatkan konsentrasi asap cair yang optimal untuk  mempertahankan kesegaran buah pisang Ambon Curup.Penelitian ini menggunakan asap cair dengan lima konsentrasi yaitu, C0 (asap cair 0%), C1 (asap cair 1%), C2 (asap cair 2%), C3 (asap cair 3%) dan C4 (asap cair 4%). Variabel yang diamati adalah, berat perbuah, berat persisir, warna kulit, warna daging buah, tebal kulit, rasa, tekstur, off flavor dan layak konsumsi / kesegaran, Hasil penelitian menunjukkan bahwa kesegaran buah terlama dapat dipertahankan sampai 14 hari pada perlakuan dengan konsentrasi 4%.

Abstract

Lemea is a traditional food from Rejang tribes that needs improvement in packaging so that the product can compete with other packaged foods. A study to get the proper packaging to maintain lemea’s quality using various types of packaging materials and storage temperatures is necessary to be conducted. The objective of this study is to examine effect of various types of packaging materials and storage temperature on quality changes of lemea. The study designed using CRD with 2 factors and 3 replications. Type of packaging material used in this research is LDPE plastic with a thickness of 0:01 mm, OPP / PP multilayer plastic with a thickness of 0.05 mm and PETE plastic bottles with a thickness of 1:25 mm; storage temperature used is room temperature at 27-32 °C and refrigerator temperature at 12-15 °C. Parameters measured were changes in water content, pH value, the number of colonies of microbes and organoleptic (color, scent, shape and overall acceptance attributes of lemea) on lemea that stored for 28 days with the observation point on day 7, 14, 21 and 28. Various of packaging materials of lemea are LDPE plastic, OPP / PP multilayer plastic, and PETE plastic bottles showed significant effect on moisture content, pH, TPC, and organoleptic in room temperature storage at 27-32 °C but it had no significant effect in the refrigerator temperature storage at 12-15 °C. The difference in storage temperature affects the occurrence of deviation or alteration of lemea quality.

Abstract

Pure honey has a good nutrient content and it is also believed it has healthy peculiar property. Coffee plants are one of the plants that are good in honey bees breeding.  Honey which is produced from the nectar of coffee flower price selling is relatively high.  In order to increase the value added of honey of coffee flower, the researchers in package design were needed to get the best one. The aim of this study was to determine the influence of image and packaging design either simultaneously or partially into purchasing decisions of pure honey consumers. Based on this research, it is known that an ideal packaging material for honey of coffee flower is a bottle compared to flexible packaging. The reason is functional: the bottle packaging is capable to fulfill its function as an efficient and effective packaging. In graphic design, the packaging of pure honey that preferred by the panelists is the packaging that has more colors contrast between its base colors and layout of the flower of coffee whereas the size of a font is already good because it is clearly legible.

Abstract

This study aimed to asses effect of different efficacious materials and types of sugar on consumer acceptance of “Koteja” (coffee with addition of sea cucumber and ginger) based on organoleptic tests (taste, aroma, and color) and to determine the most preferred coffee by consumers and in accordance with SNI. This study was conducted by using randomized completely design with 2 (two) factors; efficacious materials (Morinda citrifolia, Piper retrofractum, Syzgium aromaticum and material mix) and types of sugar (white sugar and brown sugar). Experimental data were subjected to ANOVA test followed by DMRT with 5% level of significant. The result showed that the use of Java chili (Piper retrofractum) and brown sugar was the most preferred by consumer.
