Abstract

Catfish was favored by many people, but so far their utilization has beenlimited to edible meat whereas the meat section of the catfish was less than 40%.  Bones and head catfish is a mineral-rich waste, especially calcium. The diversification attempt of proccessed catfish by using all parts of catfish was an effort to optimize the utilization of catfish, increasing the economic value and improve the nutritional value, mainly calcium. The purpose of this study was to optimized the utilization of catfish as foodstuffs by way of diversification of processed catfishto makesticks without leaving waste . The experimental design used was a complete randomized design (CRD) of one factors, namely the use of three types of raw material catfish include: meat catfish , catfish intact and waste bones and head catfish.The parameters investigated were the levels of calcium, protein, fat, water, ash, carbohydrate and hedonic test. Data were analyzed using analysis of variance (ANOVA) followed by Duncan test . The treatment of different catfish raw material usage were catfish meat, whole catfish and waste of bones and head on making sticks successively lowered the levels of the protein but on the other hand can increased the levels of calcium . This treatment affected the levels of protein, fat, water, ash, carbohydrates and calcium. Stick protein content between 9.3 - 13.63%, sticks calcium levels ranged between 0,08 - 2.74. The results of organoleptic test on sticks hedonic scale showed the sticks product which made ​​from whole fish and fish waste meat bones and head were the most preferred.

Abstract

Brokoli merupakan tanaman sayur famili Brassicaceae (jenis kol dengan bunga hijau) yang mengandung banyak serat dan antioksidan. Salah satu pengolahan yang digunakan untuk meningkatkan serat dan antioksidan adalah sosis ikan barakuda. Tujuan penelitian ini Mengetahui pengaruh penambahan brokoli organik pada pengolahan sosis ikan barakuda terhadap sifat kimia dan nilai hedonik. Materi yang digunakan  adalah  adalah ikan barakuda, brokoli organik, dan bahan pendukung pembuatan sosis. Metode yang digunakan yaitu eksperimental laboratorium dengan rancangan percobaan yaitu RAL (Rancangan Acak Lengkap). Masing-masing  perlakuan dalam penelitian menggunakan  3  kali  ulangan. Sifat kimia dan data  hedonik  dianalisis dengan uji ANOVA. Hasil penelitian pendahuluan didapat konsentrasi terbaik penambahan brokoli sebesar 10%, 20%, dan 30%. Hasil penelitian utama menunjukkan bahwa penambahan brokoli dalam sosis ikan barakuda memberikan pengaruh yang sangat  nyata (P<0,05)  terhadap  peningkatan kadar abu, kadar serat kasar, kadar protein, pro vitamin A, dan penurunan kadar lemak. Nilai  proksimat dalam g/100 g sosis ikan barakuda dengan penambahan brokoli 0%, 10%, 20% dan 30% berturut-turut yaitu air 9,074-9,668, abu 5,880-6,164, lemak 9,646-11,098, protein 38,136-39,439, karbohidrat 35,388-35,364, dan serat kasar 0,397-2,814. Nilai pro vitamin A dalam mg/100 g sosis ikan barakuda dengan penambahan brokoli 0%, 10%, 20% 30% berturut-turut yaitu 0-0,78. Penambahan brokoli dalam sosis ikan barakuda menunjukan perbedaan yang sangat nyata (P<0,05) terhadap nilai hedonik rasa, warna, aroma, dan tekstur.Kata Kunci: Brokoli, Sosis ikan barakuda, Proksimat    AbstractBroccoli is a vegetable plant from family Brassicaceae (cabbage with green flower types) that contain a lot of fiber and antioxidants. One food processing used to increase fiber and antioxidants is barracuda fish sausages. The purpose of this study to know the effect of organic broccoli addition in barracuda fish sausage on the chemical characteristics and hedonic value. The material were barracuda fish, organic broccoli, and supporting materials to make sausages. Method was the experimental laboratory with experimental design is CRD (Completely Randomized Design). Each treatment in the study using 3 repetitions. Chemical characteristics and hedonic value were analyzed by ANOVA. Preliminary research obtained adding broccoli in the concentration of 10%, 20%, and 30%. The main research results showed that the addition of broccoli in a barracuda fish sausage provide a significant influence (P <0.05) increased levels of ash, crude fiber content, protein content, pro-vitamin A, and a decrease in fat content. Proximate values in g/ 100 g of barracuda fish sausage with broccoli addition of 0%, 10%, 20% and 30% that were water from 9.074-9.668, ash from 5.880-6.164, fat from 9.646-11.098, proteins from 38.136-39.439, carbohydrates from 35,388-35,364, and fibers from 0.397-2.814. The value of pro-vitamin A in mg/100 g of barracuda fish sausage with broccoli addition of 0%, 10%, 20% and 30%, respectively were 0-0.78. The addition of broccoli in a barracuda fish sausages showed real significant differences (P <0.05) on hedonic value of flavor, color, aroma, and texture.Keywords: Broccoli, Barracuda sausage, Proximate

Abstract

Pineapple fruit is a fruit that quite easily damaged. Alternative actions that can be done to address the problem is to process the fruit into various refined products. Pineapples can be processed into syrup by using two types of extraction which are extraction directly and osmosis. Excess extraction by osmosis method is not using expensive equipment, the manufacturing process is easy and does not use chemicals that are safe for consumption.This research is compiled using a completely randomized design (CRD) factorial pattern consisting of two factors with 2 levels of treatment and repeated 3 times. The first factor is the method of extraction (E) consists of two levels: Direct (M1) and Osmosis (M2). The second factor is the boiling method (P) consists of two levels: without lid (P1) and the lid (P2). Osmosis extraction method by means of a closed boiling produces the value of total dissolved solids, sugar and pineapple syrup vitamin C content highs, respectively 3.86 g / 100g; 44.60% and 3.74 mg / 100ml. Viscosity, total acid and pH values are not affected by the extraction method and means boiling the pineapple syrup. Direct extraction method by means of a closed boiling produces the highest water content (64.83%) and the lowest sugar content (32.20 g / 100g).

Abstract

Pumpkin contains nutrients that are complete enough with carbohydrates, protein, some minerals such as calcium, phosphorus, iron, and vitamins are vitamin B and C and fiber. Yellow or orange flesh indicated very high carotenoid content and had potential to be processed into one kind of food product frozen french fries. The purpose of this study was to determine the optimum concentration of CaCl2 to produce french fries pumpkins. The study design was completely randomized with 4 treatments CaCl2 concentration,  0%, 0.5%, 1% and 1.5%. The test was done on the physical properties of texture and color, and organoleptic properties include taste, color and aroma. The results showed that the use of a solution of 1% and 1.5 CaCl2 generate texture higher than 0.5% CaCl2; The highest brightness and color value in the treatment without the addition of CaCl2. Keywords: pumpkin french fries, blanching, CaCl2

Abstract

Red ginger (Zingiber officinale Roscoe var. Rubrum) is a tropical plant that is easy to grow in Indonesia. One of the beneficial properties containing oleoresin is to cure colds and boost immunity. Diversification of processed red ginger syrup product is expected to increase the added value. Red ginger syrup is a refreshing drink that is processed with the addition of sugar into the porridge red ginger. This study aims to determine the characteristic of the red ginger syrup produced from three types of processing to test the properties of the chemical properties, physical properties and determine the level of acceptance A-panelists on red ginger syrup. This research has been carried out in the laboratory of Faculty of Agricultural Technology of 17 Agustus 1945 University Semarang.  The study design used is RAK (Random Group) with 3 treatment   (PA= with three treatments and three replications.          The treatments were performed in this study were treated with extraction (PA = extraction precipitation three times, PB = extraction and precipitation one time PC = extraction without precipitation). The results of the data obtained were analyzed using ANOVA (Analysis of Variance). Treatment precipitation extraction three times (PA), extraction precipitation of one times (PB) and extraction without precipitatin (PC) to produce a total value of pH, total acid titration, total sugar brix, water content and the highest antioxidant activity, respectively amounted to 6,33 %, 1,681 %, 56,67 brix, 40,24 % and 72,02 %. While the value of total dissolved solids and high viscosity that is equal to 44,67 mg/L and 104,78 mPa.s. The results of the sensory test analysis favored red ginger syrup is a favorite flavor = 5,73 (rather preffered), aroma= 5,76 (rather preffered) and color= 5,73 (rather preffered).
