Abstract

This study aims to determine the change pattern of  morphological and  physical traits of palm oil fruitsduring the fruit development until the time to harvest. This researchhas been conducted at PT. Panca Surya Garden’s Research Farm located in Kubang Raya, Kampar and Plant Physiology Laboratory, Faculty of Agriculture, University of Riau Pekanbaru from February to August 2016.Sixty fruit bunchs which antheses at the same day were selected at random from 7 years old oil palm trees. The fruit bunches were hand pollinated at 18 March 2016 and each was covered by pollination bag. Beginningat 30 to 120 days after pollination (DAP), 3 fruits bunches were harvested at 15 day interval. Then from 125 DAP to 185 DAP the fruit bunch were harvested every 5 days interval. The change of morphological and physical traits were observed such as fresh bunch weight, fresh fruit weight per bunch, mesocarp thickness, fruit diameter, fruit volume andfruit moisture content, and fruit color. Showed that the increase of bunch weight, fresh fruit weight per bunch, fresh fruit weight occurred at the same pattern. Fruit fresh weight and dry weight increase steadily from 30 DAP  and reached the maximum values at about 170 DAP, then decreased slightly until 185 DAP. The fruit water content increased slowly from 30 to 45 DAP, then decreased progressively untul 150 DAP and finally decreased very rapidly  from 150 to 180 DAP. Fruit color changed from dark purple to red purple and finally at harvest the color change to yellow red. Keywords : palm oil, bunch weight, fresh fruit weight, fruit dry weight

Abstract

This study aims to determine the effect of several organic materials and obtain good organic material for the growth of cocoa seedlings. The research was conducted at the Faculty of Agriculture University of Riau's experimental garden, starting from November 1, 2018 to February 28, 2019. This study used a completely randomized complete design (CRD) with 4 treatments and 5 replications so that it consisted of 20 experimental units. The parameters observed were seedling height, number of leaves, stem diameter, leaf area, root volume and root canopy ratio. The data were analyzed using variance and continued with a test of multiple levels of 5%. The administration of various organic ingredients did not significantly affect seedling height, number of leaves, stem diameter, root volume and root canopy ratio, but significantly different increased leaf area. Treatment without administration of organic ingredients can increase the leaf area of cocoa seedlings. Keywords : Cocoa, cocopeat, husk charcoal, Compost TKKS

Abstract

ABSTRACT                The study aimed to analyze the channel, structure, behavior, appearance of the deep coconut market in Tebing Tinggi Timur District, Meranti Islands Regency. This study uses a survey method. Respondents are all marketing institutions involved in marketing coconut. Sampling uses the census method. Data analysis is descriptive and quantitative. The marketing channel is seen from the product flow that the goods go through, the structure is seen from the number of actors, the barriers to entry, concentration ratio, market share and the external index. Market behavior is seen from the practice of price formation, correlation and transmission. Market appearance is seen from marketing margins, efficiency and farmer's share. The research results show the marketing channels, namely (1). Farmers sell to the collector and the collector sells to wholesalers. (2). Farmers sell to big traders and wholesalers sell to factories and abroad. The market structure is an oligopsonist, there are obstacles in and out of the market. The value of the market share at the level of collectors ranges from 0.02-0.13, at the level of wholesalers ranging from 0.06 to 0.22. The value of the herfindahl index at the level of the traders is 0.0884, at the level of wholesalers it is 0.1427. Market behavior shows the end consumer (wholesaler) who determines the price. The price of coconut at the farm level is strongly correlated with the price of coconut at the final consumer level. The value of price transmission elasticity is <1, which means that the price changes at the level of large traders are greater than the price changes at the farmer level. Market appearance, the total marketing margin for channel I is Rp. 904.81, - / Item. Costs and benefits obtained Rp. 175, - / Item and Rp. 730, - / Item. Channel II total marketing margin of Rp. 1,061.81, - / Item. Costs and benefits obtained Rp.195, - / Item and Rp. 867, - / Item. The efficiency of marketing channels I 6.57% and II 6.09% with Farmer's share 66.04%, and 66.82%. Keywords:Coconut, Marketing, Channels, Structure, Behavior, Appearance

Abstract

Bio-charcoal briquette is one of the biomass fuel. Biomass used in this research were rice straw and rice husk. The aim of this research was to obtain the best composition of bio-charcoal briquettes using rice straw and rice husk that meet the standard quality of briquette. The research used Completely Randomized Design with five treatments and three replications. The treatments were ratio of rice straw and rice husk 90:10, 75:25, 50:50, 25:75, and 10:90. Data obtained were analyzed using Analysis of Variance and followed by Duncan’s Multiple Range Test at 5% level. The result showed that ratio of rice straw and rice husk in each treatment significantly affected moisture, ash, density, bulk density, calorific value, fuel, and volatile matter. The best treatment was a bio-charcoal briquettes which made from ratio rice straw and rice husk 10:90 with moisture content 9.4543%, ash content 30.2718%, density content 1.0110 g/cm3, crushing strength content 0.0120 kg/cm2, calorific value 3794.3530 cal/g, fuel content 0.0081 g/second, and level of volatile matter 0.0198%.Keywords : Bio-charcoal briquette, rice straw, rice husk
