Abstract

The preserve quality, freshness and extending shelf life of fruit could be done by storing the fruits in the refrigerated room, pressurized room or by modifying the atmosphere of the room. However, this type of storage cost is quite expensive, therefore needed another solution that is fruit coating using edible coating solution made from vegetable hydrocolloids. The aims of this study were to determine the best materials type among the three types of vegetable hydrocoloid materials, namely extract Aloe vera leaves, extract Ceiba pentandra leaves and extract  Abelmoschus manihot leaves that are able to preserve the shelf life of M.acuminata fruit. This research use was a complete randomized design with four treatments, namely;  without edible coating, edible coating of extract Aloe vera leaves, edible coating of extract Ceiba pentandra leaves, and edible coating of extract  Abelmoschus manihot leaves, with three replications. The result showed that the lowest shrinkage percentage was found in edible coating of extract Aloe vera leaves with an average value of 3.43% and the highest was found in treatment without edible coating of 4.37%. At the end of observation the highest sugar content was obtained in edible coating of extract Aloe vera leaves of 20 oBrix while the lowest was in treatment without edible coating that was 16oBrix. In organoleptic test, panelists prefered edible coating of extract Aloe vera leaves with an value range of 4 or 5 equivalented with neutral or likes, and did not like of edible coating of wxtract Abelmoschus manihot leaves  with an value range of 3 or 4 equivalented with slightly dislike  or neutral. Based on the conducted observational, the edible coating of extract Aloe vera leaves was able to preserve the shelf life of M.acuminata fruit up to five days after harvesting

Abstract

Drought causes hampered nutrient absorption and water uptake in plants hence abnormal growth and lower yield. One of alternative solutions is the development of maize varieties tolerant to drought stress through plant breeding. This study aims to find superior M3 mutant genotypes of maize that can adapt to dry land with high productivity.  The study was conducted in green house of the Faculty of Agriculture, Universitas Hasanuddin using Split Plot Design. Water availability level was set as main plot consisted of 60%, 80% and 100% and maize mutant was set as subplot consisted of four M3 mutants, namely Bisma 100 gy, Bisma 200 gy, Lamuru 100 gy, and Lamuru 200 gy. In addition two varieties were used as controls ie. Bisma, and Lamuru resulted in total of 6 genotypes tested in the study. Mutant genotype of Bisma 200 gy showed tolerance to all water availability levels and significantly differed to other mutants including its parents indicated with higher yield. 100% water availability condition resulted in higher production than the other two water availability conditions with the average yield produced was 44.1 g per plant

Abstract

Wheat is a sub-tropical cereal that can be planted in the tropics, on the highland with altitude >1000 m asl. The development of wheat in the highlands compete with horticultural crops, so the creation of tropical wheat that is adaptive to lowland and drought tolerance is an alternative problem-solving. The aims of this study is to test the generation and to screen three type of  mutant that is adaptive in lowland with high temperature. The study was conducted at Tamalanrea Jaya, Tamalanrea regency, Makassar province from May to August 2017. The research was conducted on hydroponic media in the plastic house (green house) at altitude <800 m asl with an average temperature of 28oC (morning) and an average temperature of 33oC (afternoon). The study was used split-plot design with the main plot of polyethylene glycol (PEG), ie 0%, 5%, 10%, and 15%; the plot was 15 wheat genotypes. The results showed that the addition of PEG concentrations at 5%, 10% and 15% decreased the crop yield by 35.91%, 55.63%, and 71.83%. Adaptive and potential genotypes developed in lowland with dry climatic conditions are genotype N.200 2.4.B.6 and genotype N.300 4.3.6

Abstract

Galoba durian is one of the endemic floras from Maluku. Galoba durian is a species belonging to the Amomum genera Zingiberaceae family. It is also used as a medicinal plant for waist and kidney diseases. Based on the color of the fruit, galoba durian is divided into two nmely red galoba durian and green galoba durian. Distribution of this plant in Ambon can found in a few places such as highland and coastal area. Different locations influence phenotypic of plants, but may not show different genetic characteristic. Genetic diversity can detected by molecular markers. Genetic characterization from galoba durian using RAPD markers has not been done before. This study aimed to analyze genetic diversity from galoba durian using molecular markers RAPD. Samples of plants are used red galoba durian from Hatu and green galoba durian from Hatalae. The result of the first study, characterization of the morphology of the galoba durian, showed that both galoba have almost similar characteristics. Further DNA was tested by qualitative and quantitative. Result shows good qualitative and quantitative of DNA genomic. The second study was amplification by PCR-RAPD. DNA amplifications were performed using 3 primers out of 9 screened random primers. The primers selection was based on hight polymorphism. DNA amplification has 36 bands which were 100% polymorphic. The size of each bands from visualization of agarose was determined by linear regression. Number of band amplified was range from 120 to 1612 bp. Polymorphic band of RAPD showed the highest  genetic diversity. It can be concluded that the two plants of galoba durian are different species

Abstract

The shifting of tomatoes cultivation from upland to lowland led to a significant decrease of tomatoes production, particularly on tomatoes varieties which are not able to adapt to lowland. Genotypes selection based on appropriate selection criteria is the most effective method to obtain tomatoes genotypes with high production in the lowland. The aim of this study was to determine appropriate selection criteria in the lowland based on high heritability value, high phenotype and genotype  correlation to production component, and character relationship closeness with production component through path analysis. This study used a randomized block design with three replications. Selection criteria was chosen based on high heritability value, significant correlations in phenotype and genotype and its high direct impact on fruit weight per plant which were the number of fruits per plant and weight per fruit characters

Abstract

Wheat (Triticum aestivum L.) is a staple food for most of world population and has a good prospect considering the great potential of land to be planted with this plant species which contains carbohydrate of 70% and protein of 3%. The development of this commodity was started from agricultural extensification and production increase through the implementation of cropping system. This study was aimed to provide information on suitable cropping system for wheat cultivation and to examine the effect of cropping system on the increase in wheat production in medium land of Palopo City. This study was conducted in farmer land in Kambo Village, Mungkajang Subdistrict of Palopo City, South Sulawesi at elevation of ± 600 m asl from June until September 2017. This research uses two factor factorial in randomized block design. The first factor consisted of two cropping systems, namely line up system (S1) and Hazton system (S2). While, the second factor included two varieties, namely Guri 4 variety (V1) and Guri 6 variety (V2). Study result for vegetative phase showed that the best plant height was obtained using line up cropping system in Guri 4 variety (S1V1) with average of 73.91 cm. Implementation of Hazton cropping system in Guri 4 variety (S2V1) resulted in the best flag leaf area with average of 40.23 cm2. Hazton cropping system implementation in Guri 6 variety (V2S2) indicated the best green color with average value of 11.00 unit. Furthermore, application of line up cropping system (S1) produced the best total tiller number with average of 18.22 tillers. Therefore, it is concluded that the use of Hazton cropping system was able to increase the wheat production and Guri 4 Variety is expected to adapt to grow in the medium land of Palopo City
