Abstract

Effect of Calcium Chloride Concentration (CaCl2) and Storage Temperature on Physico-Chemical of Salacca zalacca Fruit This study aims to know the effect of calcium chloride (CaCl2) and determine the best concentration of calcium chloride and storage temperature on physico-chemical salak fruit. The research method used was split plot design which consisted of two treatments that are concentration of calcium chloride (CaCl2) (sub plot) with four levels; 0%, 9%, 12% and 15% storage temperature (main plot) with two levels; 28±2oC and 15± 2oC. The observation included weight loss, hardness, respiration rate, total dissolved solids, total acid content, vitamin C content, pH test, organoleptic test and shelf life. The result showed that storage of salak fruit with application of calcium chloride had the lowest respiration rate at temperature 28±2oC and 15±2oC. The treatment had the lowest respiration rate was concentration of calcium chloride 12% with the lowest respiration rate ( 2,54 ml/kg.hour of O2 and 2,45 ml/kg.hour of CO2). The concentration of chloride at 12% and storage at temperature 15±2oC was the best treatment to maintain physico-chemical characteristics with parameters wight loss, hardness, total dissolved solids, total acids content, pH test, and shelf life. Organoleptic test showed that a combination of concentration of calcium chloride 12% with storage temperature of 15±2°C have a level of acceptance that are favored by panelists. Calcium chloride of 12% extended the shelf life of salak fruit for 7 days at 28±2oC and 11 days at a temperature 15±2oC, respectivly.

Abstract

Influence of Mica Packaging Container Sizes on Quality and ShelfLife of Strawberry (Fragaria sp.). This study aimed to determine the effect of plastic mica container size with a total of 15 pieces of packaging and determined the best treatment for the shelf life of strawberries (Fragaria sp). This study useds a complete randomized design methodology (CRD) with one treatment, namely the type of plastic mica container size with various types of packaging types as follows: type 1 (K1), type 2 (K2), type 3 (K3) and number 15 fruit packs. The observed variables were weight loss, hardness level, shelf life, organoleptic test, respiration rate and vitamin C. The size of the packaging containers affected the physico-chemical changes in the strawberries. The treatment influenced the physico-chemical changes in the strawberries, such as the rate of respiration and vitamin C levels. The best packaging size was the smallest size (K1 ) K2 and K3 packaging container sizes. This is indicated by the lowest weight loss variable, with the value of 0.20%, the lowest value of respiration rate (20.61 CO2/ kg/hour), the highest vitamin C content (72.89 mg/100g), while in the organoleptic test, the smallest container size resulted in the highest score in fruit colour, container size has a score highest in the observation of fruit color, fruit appearance and fruit aroma. Observation of the shelf life of strawberries showed that the container size of K1 (the smallest) had an average shelf life better than K2 and K3. K1 container size produced a shelf life average of 4 days while K2 container size produce a shelf life average of 3,4 days. The shortest shelf life average was recorded in the K3 container size with a value of 3,2 days. It is concluded that the shelf life of strawberries in a packaging container at a temperature of 28-30ºC can be as long as 4 days.

Abstract

Effect of Number of Fruits and Type of Packaging on Physical, Chemical Properties and Shelf Life of Tomato Fruit (Lycopersicum esculentum Mill.) The demand for tomatoes increases along with the increase in economic growth and population. Efforts to maintain the quality of tomatoes are to delay ripening using various plastic packaging. This study aims to determine the effect of the right amount of fruit in the packaging and determine the suitable packaging in maintaining the physical, chemical and shelf life of tomatoes. The research was carried out from December 2020 to January 2021 at the Plant Breeding and Seed Laboratory, Faculty of Agriculture, Udayana University, Jl. PB. Sudirman, Denpasar. The experimental design used was a factorial completely randomized design (CRD) with 4 replications and 2 treatment factors so that 24 experimental units were obtained. The 2 treatment factors were as follows: packaging treatment (K) consisted of three treatments K0 = Control (without packaging), K1 = Polypropylene (PP) packaging, K2 = Polyethylene (PE) packaging and number of fruit (T) consisted of two treatments T1 = 3 pieces in a pack, T2 = 4 pieces in a pack. The results showed that the use of polypropylene packaging (K1) and the use of 3 packaged pieces (T1) were able to extend the shelf life of up to 22.75 days, compared to the polyethylene packaging type (K2). The smallest weight loss was found in the treatment of polypropylene packaging type (K1) at 4 Hsp which reached 0.05%. Treatment of the type of polypropylene packaging (K1) showed a low respiration rate at 4 Hsp which reached 22.88 mg CO2/kg/hour. The treatment of polypropylene packaging type (K1) showed the highest hardness level at 4 Hsp, namely 8.40 mm/100/gram/second. The results showed that the number of fruits per package had an effect on weight loss, respiration rate, and shelf life of tomatoes.

Abstract

The Effect of Chlorine Concentration and Tomato Packaging Type on Physical and Chemical Changes during Storage in Tomatoes Plants (Lycopersicum esculentum Mill.) Tomatoes are one of the important commodities that are vulnerable to contamination by various kinds of microorganisms. The thing that can overcome contamination is by washing and packaging. The chlorine compound that is most often used as a sanitizer is hypochlorite. The type of sanitizer used in this study was sodium hypochlorite (NaOCl). Packaging protects quality and sanitation so that consumers receive tomatoes fresher and quality is guaranteed, packaging should not interfere with the process of heat release from respiration. The type of packaging used in this study was LDPE plastic film and white stretch film (WSF). The design used in this study was a completely randomized design (CRD) with two factors and each combination was repeated three times, so that there were 36 experimental units. The first factor is the treatment of chlorine solution concentrations consisting of four levels: without chlorine solution, concentration of 100 ppm, concentration of 200 ppm, concentration of 300 ppm. The second factor is packaging with 3 levels of without packaging, packed with LDPE plastic film, packed with white stretch film (WSF). The results of this study indicate that the combination of washing using chlorine solution and the best packaging slows the physicochemical changes based on vitamin C variables where the decrease in fruit acid levels is shown in the 200 ppm chlorine concentration and packaged with white stretch film (WSF) treatment.

Abstract

Identification of Physiological Cooking Markers for Cucumber (Cucumis sativus L.) Seed Harvest. Cucumber (Cucumis sativus L.) has a wide adaptability to the environment. Cucumber production in Indonesia has decreased every year. The availability of quality seeds is one of the important factors in increasing the productivity of cucumber plants. This study aims to identify physiological ripening markers, especially in cucumber fruit. This study used a one-factor randomized block design method with 4 levels of treatment at harvesting age of cucumbers, namely 24, 27, 30, and 33 days after flower blooming. The variables observed in this study were; a) identification of fruit and seed maturity markers; 1) fresh weight of fruit (g), 2) fresh weight of 100 seeds (g), 3) oven dry weight of 100 seeds (g), 4) seed moisture content (%), and 5) fruit color development; b) testing of seed quality; 1) seed germination (%) and 2) seed germination vigor (%).The results showed that the right harvest time based on the character of the fruit and seeds to produce quality seeds for cucumber plants was 27 days after the flowers bloom. The character of the fruit at that time was shiny green with a yellow tinge and reached the maximum fresh weight, while the character of the seeds at that time was bright yellow seeds, with a fresh weight of 100 seeds was 3,95g and an oven dry weight of 100 seeds was 1,51g reaching the maximum weight. And seed moisture content at the age of 27 with the lowest percentage. The quality of cucumber seeds harvested when physiologically ripe was obtained with the highest average values such as seed germination (93.17%) and simultaneous growth vigor (81.83%).
