Abstract

This research was held to calculate and assess the efficiency of drip irrigation and crop water requirement of cauliflower on andosol land. The parameters observed were the efficiency of the use of water, the efficiency of the water storage and crop water requirement. The results of this experiment indicated that the lowest water consumption efficiency was occurred in the early phase of growth i.e 91,85%, the largest water consumption efficiency was occured in the middle and end phase of the growth i.e 100%. The lowest water storage efficiency was occurred at the early phase of growth ie 23,77%, the largest water storage efficiency was occurred in the final phase i.e 76,42%. Crop water requirement in the initial phase was 2.88 mm.day-1, in the middle phase of growth was 6,58 mm.day-1 and the final phase of the growth was 6.1 mm.day-1. Key words: Efficiency, Drip Irrigation, Crop Water Requirement, Andosol Land, Cauliflower

Abstract

Information system in Perbaungan irrigated area still done manually, so the storage, processing and delivery of information to be ineffective and inefficient. In the information management most the result were done by human role and took a relatively longer time. Moreover, the information seekers-and decision-makers also have difficulty in obtaining the data they need. Therefore, it is necessary to further develop of the information system. Web-based information system is considered to be a solution in order to access information faster, systematicaly and easy to use. For that a web-based information systems in the management of irrigation in Perbaungan irrigation areas Serdang Bedagai Regency was designed. Irrigated network information system was designed using PHP programming language, MySQL database and the method of system development life cycle (SDLC).

Abstract

Palm oil mill solid waste resulting from CPO production process is channeled into pond waste (Cooling Pond I). It is usually thrown to the ground so that it can contaminate the environment. This study was aim to utilize the oil palm waste as briquettes. Briquettes is one of the alternative to replace oil. Research was done by completely randomized factorial design with 2 factors i.e : density of air line (0,4, 0,8, and 1,2 cm) and Height of used cooking oil (2, 2,5, and 3 cm). Parameters observed were heating time, oil volume, and sootness. The results showed that the density of air line had a highly significant effect on the heating time, volume of oil and had no effect on the sootnes. Height of used cooking oil had a significant effect on sootness and had no effect on the heating time and volume of oil. The best treatment combination was L1T2 (0,4 centimeters density of air line and 2,5 centimeters Height of used cooking oil) with equipment heatimg time of 43,90 minute  and 1,79 gr sootness. Key words: Briquettes, density of air line, Height of used cooking oil centration, Oil palm solid waste.

Abstract

Every year the need for paper continue to rise while the raw material from wood have been harder to find, therefore and the alternative of raw materials would be of plant fibers or fibrous waste such as empty fruit bunches of oil palm and paper waste. This research was aimed to study the characteristics of paper made ​​from empty fruit bunch pulp and paper waste pulp. Therefore, a research had been conducted in May-June 2013. The making of paper was done at Jl. Roso No. 8 Delitua and the testing of paper was done in PT PDM Indonesia Laboratory, Medan North Sumatera using factorial randomized block design with one factor i.e. waste paper composition (0%, 10%, 20%, 30%, 40% and 50%). Parameters observed were grammage, tensile and tearing strength. The results showed that the composition of the waste paper had highly significant effect on grammage and tensile strength. The resulting paper could be categorized as art paper with the best results obtained from the composition of 40% (120 g of oil palm empty fruit bunches and 80 g waste paper). Keywords: oil palm empty fruit bunches, waste paper, pulp composition, paper.
