Rimau Gerga Lebong (RGL) is a superior citrus fruit of Bengkulu Province, but this fruit is easy to rot, especially if stored at room temperature, so it needs technology that able to extend its shelf life to have its maximum benefit. This study aims to explain the effect of cassava peel starch concentration plus chitosan on the quality of RGL citrus fruits for 20 days of storage and determine the best concentration applied. This study used a Completely Randomized Design (CRD) with two different factors namely the concentration of cassava peel starch; 3%, 5%, and 7% and chitosan concentration; 0.0%, 0.5%, 1.0%, 1.5% with observed variables of weight loss, hardness, total dissolved solids, fruit juice levels, and vitamin C levels observed every 5 days for 20 days storage at room temperature. The research data were analyzed graphically and used ANOVA to explain the effect and significance of the treatment to determine the best one. The results showed that the use of 3-5% (w / v) cassava peel starch combined with the addition of 0.0-1.5% (w / v) chitosan to coat RGL citrus fruits stored for 20 days at room temperature was able to reduce the rate of shrinkage weight so that the value is only around 6.33-8.12%; able to maintain fruit hardness so that the value ranges from 1.3 to 1.7 kg; able to maintain total dissolved solids so that the value ranges from 10.8 to 12.6o Brix; able to maintain juice levels so that the value ranges from 53.61 to 73.00%, and is able to suppress the rate of decrease in vitamin C so that the value ranges from 1.52 to 2.38 mg / 5ml. The recommended concentration of cassava starch to be applied is 5% (w / v) with chitosan added with a concentration of 1.5% (w / v).

Lanzones is a highly perishable fruit because the fruit skin will turn brown within 4 or 5 days after harvest so that the necessary methods of proper post-harvest handling. One alternative that can be used to extend the shelf life lanzones cost is relatively light coating lanzones with chitosan. Chitosan coatings have the ability to delay or slow down the process of extending the maturity and post-harvest storage. Research has been conducted in order to study the effect of chitosan on shelf life, physical and chemical properties of lanzones. The study was conducted in three stages namely stage dilution of chitosan in acetic acid, fruit coating stage lanzones with chitosan solution and analysis phase . The study design used was a completely randomized design, with 2 treatment that chitosan treatment concentration ( 0.5 %, 1.5 % and 2.5 % ) and treatment of immersion time (30 and 60 minutes). The next stage is the lanzones fruit storage at room temperature and shelf life prediction analysis with conventional methods, the analysis of physical ( texture and fruit weight) and chemical analysis (water content and the level of sweetness). The results showed that the use of chitosan coating to prolong the shelf life of lanzones up to 6 days, with the best treatment using 1.5 % chitosan and immersion time of 30 seconds. The higher concentration of chitosan is given, change the texture softening and decreased fruit weight more slowly , with the value of the texture and weight of fruit on the 6th day in a row from 225.83 to 234.59 g / mm and 19.70 to 23.47 g per fruit. Based on the chemical properties of the water content and total dissolved solids , it is known that chitosan coating could inhibit the decrease in water content and total dissolved solids. The immersion time of 30 and 60 seconds is not a real effect. Observations on the 6th day of storage for water content , ranging between 84.44 -87.71 % , while the total dissolved solids ranged from 17.22 to 20.12 % Brix.Keyword : duku, chitosan, shelf life

Tempoyak is a durian processed foods obtained by simple fermentation , the shape of the pulp of durian flesh with a sour taste. Tempoyak made with the addition of as much as 1-5 % salt into the flesh of the fruit pieces which are then brooded for 3-4 days. This study aims to determine the level of consumer preference towards tempoyak sauce with the addition of cassava tapai. The method used in making sauce with the addition of cassava tapai tempoyak, namely by processing cassava into tempoyak with tapai tempoyak sauce. The treatment in this study is the composition variation tapai cassava ( tempoyak 500 grams : 0 grams tapai cassava , tempoyak 450 grams : 50 grams of cassava and tempoyak tapai 400 grams : 100 grams tapai cassava ). The analysis used was the analysis of organoleptic parameters premises color, flavor, and aroma of chili tempoyak tested against the 20 panelists. The results of the analysis conducted stated that based on the parameters of color, showing significant difference between the three samples . Where consumers prefer chili tempoyak with the addition of 0 grams and 50 grams of cassava tapai. Based on the parameters of taste , showed no significant difference among the three samples. Based on the parameters of aroma , showing significant difference between the three samples. Where consumers prefer chili tempoyak with the addition of 50 grams and 100 grams of cassava tapai.Keywords : Tempoyak , tapai cassava , chilli tempoyak

Banana flour noodles are processed products of banana length , where in the processing process is fairly easy . Banana flour noodles in the treatment process through several stages of the process of sorting , washing , mixing , molding until boiling . Of these processes are one of the processes that determine the quality of banana flour noodles can be determined from the organoleptic properties of banana flour noodles . The purpose of this study was to determine the effect of the addition of banana flour on the organoleptic quality of banana flour noodles.The study was conducted with three treatments , namely the first treatment process carried out by the addition of 100 grams of banana flour , the second treatment is done by adding 200 grams of banana flour and treatments to three performed with the addition of 300 grams of banana flour .

Jeruk kalamansi merupakan salah satu produk unggulan di Provinsi Bengkulu dan memiliki potensi yang cukup baik untuk dikembangkan. Salah satu alternatif pengolahan jeruk kalamansi yang bisa dilakukan adalah dengan mengolah menjadi marmalade. Tujuan penelitian ini adalah mengetahui pengaruh konsentrasi gelling agent dan sukrosa terhadap sifat kimia dan organoleptik marmalade jeruk kalamansi dan menentukan jumlah konsentrasi gelling agent dan sukrosa yang menghasilkan marmalade dengan mutu terbaik. Penelitian ini menggunakan Rancanagan Acak Lengkap (RAL) dengan dua factor beda yaitu jumlah sukrosa (65%, 70%, 75%) dan jenis gelling agent (pektin (1%) dan karagenan (1%)). Parameter yang diamati meliputi sifat kimia (kadar air dan total padatan terlarut) dan sifat organpleptik (warna, aroma, rasa). Hasil penelitian menunjukkan Penggunaan pektin 1% akan menyebabkan kadar air marmalade jeruk kalamansi lebih rendah dan total padatan terlarut menjadi lebih tinggi dibanding penggunaan karagenan 1%. Penggunaan gula 70% menghasilkan warna marmalade jeruk kalamansi yang lebih disukai tetapi penambahan gula lebih dari 70%, warna marmalade semakin tidak disukai. Interaksi penggunaan konsentrasi sukrosa dan gelling agent hanya memberikan pengaruh pada warna marmalade jeruk kalamansi yang dihasilkan. Kata Kunci : jeruk kalamansi, Marmalade, gelling agent, sukrosa, karagenan, pektin
