Abstract

This study aims to determine the influence of motivation, competence, social environment and interaction with the facebook for high school students learning attitude. The study was conducted in August 2013 in SMK Bonavita Tangerang Jl. Kanjeng Dalam Tangerang, using survey methods. As a sample of this study is the purity of high school students selected (purposive sampling). This research conducted at the beginning of the school year 2012 / 2013 which includes all high school students Purity of class X, XI and XII Multimedia. Results of hypothesis testing showed that the final model obtained in this study is that facebook is very influential on high school students learning attitude Purity. Variable LS (social environment) are influenced by variables moderasinya (LSFB) affect the ATTITUDE variable. The influence of variables interact with the variable FB LS (social environment) affect the variable Attitude. Has a degree of influence of 0.511 (51.1%). The methode of this research is interview, observation and literatur.

Abstract

One of the methods in the application of Network Planning on construction projects is the Critical Path Method (CPM).Use of critical path method is to be able to know the the critical path of a project in which an activity can not be delayed, so that the execution time can be controlled to determine the earliest and the latest of starting time. As such factors can delay the project in minimizingRoad Improvement Works Sp. Berembang - Sp. Small Jambi has a contract value of Rp. 9,969,162,000.00 and the turnaround time is 217 calendar days. Application of CPM on the job resulted in an accelerated completion of work to 210 calendar days and 6 work items that are on the critical path. Acceleration time of completion of the work provides implementation costs Rp. 9,956,247,162.00 or additional profit of Rp. 12,914,838.00.Keyword:  Time management, Critical path method, road construction

Abstract

A research conducted in Sungai Rumbai, Dharmasraya Regency and in Soil Laboratory Andalas university was aimed to evaluate soil fertility status on the depth below 0-20 cm from several land use types , especially under Mixed Garden and annual cultivated dryland soil.  Soil samples were taken on Ultisol at 0-8% slope (late-waving soil surface).  Land use types evaluated were forest, annual cultivated dryland, bush land, rangeland covered by Imperata cylindrica and mixed garden.  Composite soil samples for soil chemical analysis were taken on the 0-20 cm soil depth with four replications, and 5 drillings for each replication.  Undisturbed soil samples by using sample ring were used to analyze sol bulk volume.  The data resulted were compared to the criteria and were statistically tested using Analysis of Variance and then were continued by LSD at 5% level.  From the results of analyses could be concluded that land use  for mixed garden had the higher Organic Carbon (OC) content and the lower bulk volume (BV) than those for annual cultivated dryland soil.Key Words: Degradasi Lahan, Kebun Campuran, Tegalan

Abstract

Component-Level Domestic Content Policy (TKDN) encourages the utilization of domestically produced medical devices; however, their accuracy and safety must be proven. This study aims to analyze the accuracy of domestic infusion pumps using the uncertainty measurement method. A total of four units from four brands (Endo, ESA Tech, Inmedik, and Krisma Care) were tested on the flow rate parameter with variations of 10, 50, 100, 200, and 300 mL/hour. Each test point was measured six times using a calibrated Fluke IDA 5 Infusion Device Analyzer. Data were analyzed through calculations of mean, correction, standard deviation, and expanded uncertainty (k = 2). Based on the analysis results, all TKDN infusion pumps (100%) met the tolerance limit of ±10% in accordance with the PO.002-18 standard and were declared fit for use. The highest correction value of 25.57 mL/hour (8.5%) was recorded for the Endo brand at a setting of 300 mL/hour, while the lowest correction of 0.21 mL/hour (0.7%) was found in ESA Tech. All measurement points across the four brands showed consistency within the permitted tolerance limits, with measurement uncertainty variations between ±0.15 and ±0.17 mL/hour. These findings prove that domestically produced infusion pumps possess accuracy and reliability equivalent to the standards required for clinical use.
