Abstract

The effect of using various packaging treatments on extend the shelf life of strawberry fruit and their physico-chemical changes Strawberry is one among horticultural commodities that has a significant potential being developed commercially in Bali. Strawberry fruit commonly has a relatively sweet taste and a strikingly bright red color. Strawberry fruit is easily damaged and has a short shelf life, so it is necessary to inhibit the damage, among others by the use of various packaging treatments. This study aims to extend the shelf life of strawberry fruit and the effect of using various packaging treatments on their physico-chemical changes. The experimental design used was completely randomized design with one packing type factor consisting of 3 treatment levels, ie without packaging, use of mica package, and use of styrofoam package.The results showed that strawberry fruits treated with mica and styrofoam pacgages had a longer shelf life than strawberry fruit stored without any packaging (control). The storage period of strawberries both treated with mica and styrofoam packeges were last up to the 4th day. The use of mica package showed the best results with the lowest shrinkage value, lowest softness, low respiration rate and high organoleptic value. Eventhough strawberry fruit packed with styrofoam package showed a high vitamin C content, but the strawberry fruit packed with mica package has a better visual appearance with good fruit quality and mostly accepted by the panelist.

Abstract

Tolerance of Processing Delay to Physical and Physiological quality of Soya Bean (Glycine max L. Merril) The aim of this research is to figure out the time of the tolerance processing delay so that the physical quality and the physiological quality of soya bean seeds could be defended. This research was started in April 2017 at Jalan Cekomaria, Denpasar and also at the Lab. Pemuliaan Tanaman dan Teknologi Benih Faculty of Agriculture Udayana University. The design method was used for this research is a randomized complete block design (RCBD) using five treatment and five-time repetitions consist of W0= Without using process, W1= 1 day of Delaying process W2= 2 days of Delaying process, W3 = 3 days of Delaying process, W4 = 4 days of Delaying process. The statistic test and analyzing variance statistical test shows different result, the procedure followed by LSD method (Least Significance Different) with 95% of confidence level using costat program.The result of physical analysis test, shows that the role of the seeds which is without delaying process showing that the percentage of the seeds was 87,36% and the result of 4 days delaying process seeds are 11,256%. The result of the physiological test of the seeds using germinating test was, W0 (95,16%) and W4 (94,72%). The percentage of the vigor will be decreasing, which is W0 (80,52%) and W4 (34,4%). The equality control of the percentage was W0 (90,3%) and W4 (70,68%). Result of the observation of electrical conductivity showing that the lowest point of the electrical conductivity control is W0 (5,112 ? mhos cm¯² g¹) and the highest value of electrical conductivity was shown on the W4 (7,302 ? mhos cm¯² g¹).

Abstract

Identification of landslide potential in Baturiti District Tabanan Bali Districts Baturiti has most areas with a slope above 15%, land use as seasonal crop farming and rainfall is high enough to potentially the occurrence of landslide hazard. Based on the above, it is necessary to conduct research on potential landslide with the aim to know the level of landslide potential and map the potential spread of landslides in Districts Baturiti. This research was conducted from February to August 2017 with survey and scoring method. The study area has 12 units of land covering the low landslide potential class of 61764.2 hectares (77.1%). is present in the area represented by the land units 1,2,5,6 and 9. The medium landslide potential class of 9415,8 ha (11,7%) is in area which is represented by unit of land 3,7,10. The high landslide potential class of 8959.4 ha (11.2%) is in the area represented by the land unit 4,8,11,12.

Abstract

The Effects of Processing Delays on Storage Ability of Soybean Seed (Glycine max L. Merril) Soybeans are the third important food crop in Indonesia after rice and maize. Proper handling or seed processing will affect the quality of the seeds obtained. Generally soybean seed can be stored for 3-4 months with the correct handling process. Delays in seed processing affect the appearance of seed quality both physical and physiological. Weather factors and facility limitations are the reasons for delaying seed processing after harvest. Soybean seed storage is important because soybean seeds are likely to be stored before the seeds are planted. This study aims to determine the effect of delayed processing that can be tolerated to store ability of soybean seeds. The experimental desain used was Completely Randomized Design (RAL) by a single factor with a processing delay which is consisting of five treatments and five repetitions. The observed variables were moisture content (%), germination (%), vigor saving test (%), growthability test (%), and electrical conductivity test (?mhos cm-1 g1).The results showed that delays of processing time after harvest in soybean seeds can effect the shelf life. The longer the processing time was delayed, the lower the storage ability of the seed. Seeds without delay in processing time can maintain seed viability for eight weeks of storage with the lowest electrical conductivity of 2,47 ? mhos cm-1 g1. Processing one day delays and two day delay after harvest can be tolerated because the seeds produced have a germination greater than 80% and still meet the standard of seed quality.

This onion tuber harvest after treatment with insecticide with 40% active metomyl.this research was done from 2016, November until 2017 January. Randomized block design was used in this studay with 5 treatments and replicated 5 times. The results showed that the perceutage of demage caused by Spodoptera exigua on onion plant treated by metomiyl insecticide 40% were significant different compare to control. The highest percertage of damage was found in control 13.5% and the lowest percentage of damage was found in treated consentration of 2,00 g/l, was 1,99%, both was observed in 49 days after transplanting, the production of wet tuber in average was found 1,3 kg in treatment of 2g/l and 1,1kg in countred, the production was calculated by avrage of 10 plants. The relationship between percentage of damage and production are very weak to strong unsignificant and reversely propotional.

Abstract

Evaluation of Land Suitability for Robusta Coffee Plant (Coffea canephora) in Pajahan Village, Pupuan Sub-district, Tabanan Regency Robusta coffee (Coffea canephora) is one of the agricultural commodities that have a profitable prospect. Pupuan sub-district is concentrated of Robusta coffee in Bali Province. Pajahan Village is one of the 14 villages located in Pupuan sub-district which also built Robusta coffee. Based on data from the Central Bureau of Statistics (CBS) of Pupuan Sub-district, coffee production in Pajahan Village has continued to decline since 2012 until 2016. Evaluation of Land Suitability is a way to know the limiting factor in the research area. Land evaluation conducted by matching method between land characteristic / quality with growth requirement of plant evaluated. The research was conducted in Pajahan Village, Pupuan Subdistrict and Laboratory of Soil, Faculty of Agriculture - Udayana University. The research was conducted from October to December 2017. The results showed that the actual land suitability classes on the IILckK land unit is S3na2, IIILckK is S3na2.eh1 and IVLckK is Neh1. Fertilization, addition of organic matter, terracing and proper land cover can increase the class of land suitability to be appropriate marginal (S3) to very appropriate (S1). The limiting factor of dry season and moisture is a major limiting factor that can not be repaired.
