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 Discovery of the Content of Giberellin Acid (GA3) in Extracts of Several Plant Spesies. Several studies have found that the application of growth regulator Giberellin can induce seedless in seeded varieties and also improve fruit quality in non-seeded varieties of grapes. It is also directly responsible for cell division and is used in horticulture to promote seed germination. The high price makes it unaffordable for farmers, especially in Indonesia, so it is necessary to look for other sources of GA3 which comes from extracts of plant species in Indonesia. The aims of this study were: To detect the content of gibberellin acid (GA3) in several plant species; The research was conducted at the Agronomy & Horticulture Laboratory, Faculty of Agriculture, Udayana University. The results of the study found that fresh corn kernels (Zea mays L.), young bamboo shoots (Bambusa sp.), fern leaves (Diplazium esculentum), spinach leaves (Amaranthus spp) and shallot bulbs (Allium cepa), contained as much as 215 µg GA3 mL-1, 257 µg GA3 mL-1, 260 µg GA3 mL-1, 154 µg GA3 mL-1 and 227 µg GA3 mL-1 respectively. It can be concluded that extracts of plant materials contain GA3 and can be used as a substitute for synthetic GA3.

Abstract

Tomatoes are one of the daily necessities for people. In general, consumers favor tomatoes with few seeds. Therefore, there must be efforts made to improve the quality of tomatoes, one of which is to reduce the number of seeds, even if it is possible to make tomatoes without seeds (seedlessness). By applying Gibberellic acid (GA) during the growth phase of tomato plants, it is possible to enhance tomato quality through technology. The application of GA to certain plants can reduce the number of tomato seeds and increase their sweetness. It is necessary to discover a way to use GA-containing natural ingredients to prepare for the high cost of synthetic GA. Onions are one of the natural ingredients that contain GA. Thus, this study aimed to examine the effect of applying onion extract as a source of GA to obtain the optimum concentration of onion extract that can improve the quality of tomato fruit. The experimental design utilized Randomized-Group Design with five different treatments: no spraying, spraying with 25%, 50%, 75%, and 100% onion extract. According to the findings, the application of onion extract improved the quality of tomato fruit. This condition is reflected by a decrease in the number and weight of seeds per fruit and an increase in the fruit's vitamin C content. Therefore, it is essential to conduct this research to produce inexpensive, high-quality tomatoes to sustain the economy and increase farmers' income

Abstract

Tabanan is one of the regencies in the province of Bali. The city also has a city park which is named Taman Bung Karno Tabanan. This park certainly has recreational activities in it, one of which is extreme sports such as skateboarding. However, this activity is considered to interfere with park visits, judging from the issues that say that skaters often damage public paving and planter facilities and also disrupt the circulation of park visitor activities. This is the background for the author to raise the issue as research material, with the aim of this study being to find out the perceptions and preferences of park visitors and skaters, so as to obtain solutions to overcome the problems of visitor comfort and skateboarding activities. The research method used is a survey method with data collection techniques through observation, interviews, questionnaires, and literature study. Based on the results of the study, visitors rated the level of comfort at the Bung Karno Tabanan City Park as adequate with a percentage of 49.9% with a preference of park visitors of 72.1% wanting the addition of skateboard facilities. Suggestions that can be given to increase comfort at Taman Bung Karno Tabanan is that there is a need for additional skateboarding sports facilities or can be relocated to a more appropriate place.

Abstract

Effect of Seed Storage Time and Coconut Water Soak Concentration on Viability of Rice Seed (Oryza sativa L.). This study aims to determine the effect of seed storage time and concentration of coconut water immersion on viability of rice seeds (Oryza sativa L.). This study used a completely randomized design (CRD) split plot. The main plot is the storage time of seeds consisting of 3 levels, namely storage time of 7 months (L1), 8 months (L2) and 9 months (L3). Sub-plots were the concentration of coconut water immersion consisting of 4 levels, namely immersion without coconut water (K0), 10% coconut water (K1), 20% coconut water (K2) and 30% coconut water (K3). Each treatment was repeated three times. This research was carried out at the Plant Breeding and Seed Technology Laboratory, Faculty of Agriculture, Udayana University from October 2021 to December 2021. The results showed a storage period of 7 months and a concentration of 10% coconut water (L1K1) which had the highest growth rate of 84.00% compared to with a storage period of 9 months and without soaking coconut water (L3K0) which has the lowest value of simultaneous growth of 52.00%. The storage period of 7 months gave the highest value for the variables of growth speed (23.96%/etmal), simultaneous growth (79.42%), germination (96.17%) and maximum growth potential (97.42%) compared to storage time. 8 and 9 months. The 10% coconut water concentration gave the highest value for the variable growth speed (23.65%/etmal) and maximum growth potential (96.44%) compared to no coconut water immersion. The concentration of 30% gave the highest value for the simultaneous growth variable (75.22%) compared to no coconut water immersion.

Abstract

Effect of Several Concentrations of Floralife Preservatives to Hyrangea (Hydrangea macrophylla) Cut Flower Freshness Hydrangea (Hydrangea macrophylla) is one type of flower that can be used as cut flowers but has a short vase life of flower freshness. One way that can be done to prolong flower freshness of cut flowers is by using pulsing solution. This research aims to study the use of cut flower preservatives and to obtain the best concentration of pulsing solution using Floralife preservatives in maintaining the freshness of hydrangeas. This research was conducted from January to March 2022 at the Agronomy and Horticulture Laboratory, Faculty of Agriculture, Udayana University. This study used a completely randomized design (RAL) based on single factor of concentration of Floralife preservatives which consisted of distilled water (P0), Floralife concentration of 5,000 ppm (P1), 7,500 ppm (P2), 10,000 ppm (P3) and 12,500 ppm (P4). The results showed that the pulsing solution using Floralife preservative with a concentration of 10,000 ppm (P3) gave the best results, the vase life of hydrangea cut flowers reached 12.8 days (or 8.4 days longer than soaked with distilled water) with the highest total absorbed solution.
