Abstract

The background of the problem in this research is the learning difficulties experienced by thestudents of class I Proggram of Mechanical Expert Automotive SMK N 5 Semarang academic year2016/2017 which indicated less than optimal learning achievement. This background becomes thebasis of research. The purpose of this study is to mengetehui level of difficulty belaajr students SMKN 5 Semarang, especially class I Automotive Mechanics Expertise Program. In addition, the mainobjective to be achieved is to determine the dominant factors that cause the difficulty of learninggrade 2 students of Automotive Mechanical Skill Program of SMK Negeri 5. In accordance with thepurpose of research into the study population is a class I in the academic year 2016/2017. Themethod of collecting dta used there is 2, that is documentation method to determine population. Inthis case the documentation is in the form of a list of student names. The second method is thequestionnaire method. Questionnaire was prepared using a lattice consisting of 33 sub factors and 66items. Based on the results of the test instrument performed by students of grade 3 MO 1 academicyear 2016/2017, the analysis results obtained 52 valid questions and 14 invalid questions. Ininstrument testing, the price of r11 is greater than the reference price of 0.30 so that the instrument isreliable and can be used as a test instrument. Then taken 33 questions sesui with sub factorrespectively. Data analysis technique used is descriptive analysis technique percentage. Thistechnique uses a comparison of the student scores with an ideal score. Overall the total score ofstudents studied is 2470 of the entire ideal score of 5280 or 46.78%. Based on predeterminedcriteria, this percentage belongs to less problematic category. Of the 32 respondents studied, all hadproblems learning in the less problematic category. The number of scores per sub-factor showsdifferent categories. Sub factor of family environment, society environment included in less problemcategory. While the sub-factor of the school environment into the category is quite problematic.Based on the results of the above research can be concluded that the level of difficulty learning siswamasuk dalm less problematic category. The cause of students' learning difficulties fromextracurricular factors is very dominant as a learning difficulty factor.For teachers should be as early as possible to identify the learning difficulties experienced bystudents so that it can help solve it. For SMK N 5 Semarang should always fix the condition of theschool so that the teaching and learning process can take place properly.Keywords: Learning Difficulties, Automotive Mechanics

Abstract

ABSTRACTThe aircraft streeing gear is one of the auxiliary machineries that functions forchange and determine the direction of motion of the ship, both straight and turn the ship, to the left (portside) and to the right (starboard side), by moving the rudder (steering wheel). MethodThe research used in this study is a quantitative method. Data analysis techniqueusing the Urgency, Seriousness, and Growth (USG) method by determining priority levelsIssues use a scale of numbers in order to get an effective and effective issue resolution withmaintain the performance of Steering Gear in SV. SWISSCO SAMSON then do maintenanceand repairs as desired. Based on the results of research that has been done by researchers,steering gear does not work optimally, caused by not operating the system value properly,there are several bolts or connections (connectors) to the pipe that loosens, the quality and type of oilimproper hydraulic applications, damage to seals and o-rings. Decreased pump performancehydraulics, caused by leakage of pipe joints, damage to valves, loss of qualityhydraulic oil, dirty or clogged filters and leaks in hydraulic cylinders. To overcomethese factors can be done by regularly checking the electric-hydraulicsteering gear, checking the pump, checking the pipe leading to the pumphydraulics, hydraulic pump valves, hydraulic oil quality checking

Abstract

This study seeks to create and implement an IoT-based tank level monitoring system to rectify the inefficiencies associated with human sounding methods typically employed on ships.  Manual measuring methods can lead to protracted processes and human errors, thereby affecting data precision and operational safety.  This research addresses these restrictions by integrating an ESP32 microcontroller, HC-SR04 ultrasonic sensor, and the Blynk IoT platform to develop an automated monitoring solution that transmits real-time water level data to a mobile dashboard.  The system was developed utilizing the Waterfall Model, which includes the phases of requirement analysis, system design, implementation, testing, and maintenance.  The proposed system exhibited great accuracy within a range of 2–400 cm and maintained stable Wi-Fi connectivity without signal loss, achieved through iterative development and expert validation.  The Blynk interface effectively provided real-time viewing of water height and volume.  An analysis of user input revealed a favourable reaction, with an average rating of 3.8 on a 5-point scale, indicating system usability and efficacy.  The results validate that the suggested IoT-based monitoring system provides a dependable, cost-effective, and scalable substitute for manual measurement, enhancing both operational efficiency and maritime technology education.
