Abstract

The aim of study is to analyze the factors that affect the production of organic rice farm and non-organic rice farm businesses, comparison of organic rice farm and non-organic rice farm businesses and analyze appropriateness of organic rice farm and non-organic rice farm businesses in researh area. The method of study that used was multiple linear regression analysis, method of cultivation analysis and feasibility analysis. The data used is primary and secondary. The result of study concluded on the independent variabel analysis of organic rice farm and non-organic rice farm businesses, the most dominant in influencing the output on organic rice which are pesticides and fertilizer. Meanwhile, the rice farm is non organic, the most dominant in influencing the output on non organic rice which are seeds and breadth of land. Organic rice farm incomes in Lubuk Bayas village Perbaungan sub district Serdang Bedagai regency is Rp 25.753.659,/ha and the income of non organic farm business is Rp 20.503.554,-/ha.

Abstract

The effect of Mt. Sinabung eruption has profoundly affected the quality of fruit and vegetable production, in this context is fruit and vegetables. Fruit and vegetable, carrot, strawberry and pakcoy is kind of fruit and vegetable that is consumed by the community especially the communities surrounding both the mountain ranges and the general medan area. The fruit and vegetable are kinds of climateric and the lifespan must be kept. During the transportation of field to market, there wa both mechanical and physical damage.The damage will obviously harm farmers, merchants, and other marketers. So that hydrocooling is applied as a post harvest treatment. Hydrocooling is done right after the harvest, This prosess extracts heat from fruit and vegetables so that respiration and transpiration can continue for a long time.The lack of farmer understanding for post harvest handling is a major problem. Therefore, farmers in aberastagi will be given education and training about post harvest handling (hydrocooling) so they could understand and self applying that will keep their produce fresh. As for the output of this activity is a simple hydrocooling device designed as a visual aid in training. This hydrocooling equipment can also be a reference to training science for schoolchildren in particular agriculture schools and could be a referenceto researchers and developing them.

Abstract

The diversity of the Durio genus in West Kalimantan is the highest in Indonesia, one of which is Pekawai (Durio kutejensis). The loss of pekawai genetic resources is a threat due to deforestation. So that real efforts are needed through intensive development through ex-situ and in-situ conservation. The purpose of the study was to obtain information on the morphological diversity of the Pekawai in the Experimental Garden of the Kapuas Sintang University. The research method used purposive sampling, the observed morphological characters were 24 characters consisting of 7 stem characters, 11 leaf characters and 6 fruit characters. Morphological descriptions were analyzed by scoring cluster analysis and dendrogram using the Unweighed Pair-Group Method Arithmetic Average (UPGMA) using the Numerical Taxonomic and Multivariate System (NTSYS) version 2.10 program. The results of the study were 24 morphological characters of leaf stems and fruit against 7 accessions of Pekawai which had a similarity coefficient of 0.78-0.96 or a diversity of 4%-22%. At the coefficient of 0.83 formed 3 main groups. Group I there are 4 accessions with a similarity of 11 characters. At a coefficient of 0.87, they formed 2 groups, 1. UNKA1 and UNKA2 with 21 morphological similarities. 2. GM2 and GM 3 with 20 similarities. Group II. Grouped based on 19 morphological characters, namely GM2 and GM3. Group III. GM5 Morphological similarity 11 characters. The conclusion is that the morphological characterization of 7 Pekawai accessions is known to have a similarity at a coefficient of 0.78 or a diversity of 22%
