Abstract

The very large numbers of trash in the TPA (end disposal place) will cause the natural decomposition process goes on massively as well. The decomposition process will change trash into organic fertilizer that if there any water input from the outside, it will dissolve metals that later become the byproduct that is leachate. The introduction of chemical contained in the leachate into the waters ecosystem may also affect the existing biota. Therefore, it is need the waste treatment before released into the environment. Leachate waste treatment by using the phytoremediation principle by means of Bambu air plant (Equisetum hyemale), with zeolite planting media was to be the choice in the effort of liquid waste treatment the Phytoremediation system was taken with a various considerations that very potential to develop into new innovation in the process of leachate waste treatment.This research had the purpose to know the effectiveness of phytoremediation system using water bamboo plant (Equisetum hyemale) and zeolit planting media by batch system and continue system in reducing Pb and Cr heavy metals contents of leachate. Research method used was the experimental method. Observations carried out involved environmental temperature and humidity, solution pH and treatment temperature, Reduction of Pb and Cr Metals Contents on leachate.Batch system and continue system as a whole, mean of leachate pH tested during this treatment was about 7,466. Leachate pH tested did not less than 7,200 and not more that 7,810. Mean of leachate temperature from the first week through third week was of 22,283°C. The best treatment was on the K­2S1 (60 batch system plants) treatment with reduction of Pb metal content of 82,2% in the last week of observation.

Abstract

Biomassa originated from palm oil plant is potential to be processed into various industrial products. In the production line this material needs to dry into certain level of moisture content, mostly about 10% (wet basis) and commonly called as dry material. It is advantageous if the dryng time to produce a dry material can be predicted. Prediction is usually approached by setting up drying model of the material. The most common drying model in formulated in the form of moisture ratio in function of drying time in which the moisture content is calculated in dry basis. On the other, in practice, the moisture content of material is expressed in wet basis. The objectives of this research were to determine the drying curves and to predict the drying times of palm oil empty fruit bunches, stem and fiber dried from solar dying and oven drying. Three series of experiments were carried out according to the types of materials. The results of the experiments revealed as follows. The curves produced by the solar energy dryer operating at drying temperatures ranged from 42oC to 54,5oC for both empty fruit bunches and stem were quadratic whereas the curves produced by the oven having temperature of 105 oC for stem and fiber were linear and quadratic respectively. The form of curves obtained from the relationships between materials moisture contents determined in wet basis and drying times were similar to the curves of materials moisture ratios in function of drying times. The drying times of the solar energy drying for the empty fruit bunches were 20 hours dan 19.3 hours for Dura variety and Tenera variety respectively while those of stems were 16.3 hours and 17.9 hours respectively for Dura variety and Tenera variety. The drying times of the oven drying for the stems were 7.1 hours, 6.9 hours and 5.0 hours respectively for the lower, middle and upper parts of the stems. The drying times of oven drying for the fibers were 6.4 hours and  6.2 hours respectively for the outer and inner field stacks empty fruit bunches origins

Abstract

This research aimed at identifying the wastes of plywood production in PT Sumber MasIndah Plywood. Results were then utilized to determine methods in reducing wastes. Theidentification of waste was carried out using lean manufacturing approach. The data werecollected from manufacturer records, study to determine processing time, as well as interviewand quisioners which were distributed to workers in each department. Big picture mapping andvalue stream mapping tools (VALSAT) were then utilized to process the data. Results ofanalyses using big picture mapping showed that total production lead time was 438,8 minutes,with 235,97 minutes of them were value added activities; and 27 days of total information leadtime. Workshop waste analyses resulted in the highest waste generated during plywoodproduction process. Those were 133 waiting time (delay), 113 defect and 78 excessivetransportation. Further analyses using VALSAT showed three methods to identify the data inmore detail, namely process activity mapping (PAM), supply chain response matrix (SCRM)and quality filter mapping (QFM). Results from PAM method revealed 125 activities duringproduction, consist 62 value added activities, 33 necessary but non value added activities and 30non value added activities. While results from SCRM showed the average 22,63 days of totalorder fulfillment process comprised of 4,13 days of total physical stock and 18,5 days of totallead time.
