This research is a classroom action research that aims to provide solutions on how to solve learning difficulties faced by class XI students of Industrial Mechanical Engineering, SMK Negeri 4 Cilegon, which are related to the subject of machine production and construction processes. At this time the learning method uses the Student Teams-Achievement Divisions (STAD) model which is packaged modularly , in the hope that students can develop their own potential independently so that they can complete the learning material thoroughly (mastery learning) but student achievement still does not show the expected results . The implementation of this class action research was conducted in two cycles using JIGSAW cooperative learning methods that can improve student achievement and student activity participation . This result can be seen from the first formative test, where the class average value is 4.05 , and through observing the percentage of student activity participation of 50.92% . After classroom action research (CAR) was held the student learning outcomes showed a significant increase . In the first cycle, the formative test results obtained a mean grade value of 5.54 and student activity participation of 52.38% (very good) . In the second cycle, the formative test results obtained a mean grade value of 6.20 and student activity participation of 66.67% (very good) . As for the learning completeness criteria, the first cycle was obtained 52.38%, the second cycle was 66.67%.

Lecturers in study programs make a major contribution to the quality of study program accreditation, particularly in the upcoming IAPS 4.0 completeness. The lecturer base needs to be managed through a concrete, transparent, structured, comprehensive, and accountable system. Lack of data management in lecturers at the Mechanical Engineering Education / PTM Study Program so far is still paperless based so that it is less effective, efficient, having to copy documents, and tends only to collect data close to the accreditation of study programs. This research aims: (1) to produce e-monitoring products on the performance of lecturers based on a cloud computing system; (2) knowing the level of feasibility of e-monitoring products on the performance of lecturers based on cloud computing system at PTM Study Program. The research method uses Research and Development (R&D), which adopts the ADDIE (Analysis-Design-Development-Implementation-Evaluation) model. The research sample was 11 PTM lecturers. Validators of eligibility included the chairman of the LPM and the chair of the UST IT team. The instruments used included questionnaires and documentation. This research succeeded in producing a product in the form of a cloud computing system with a private cloud type with the Platform As A Service (PaaS) model. The data used as an assessment of lecturer performance include governance, HR performance, education performance, research performance, and service performance. The results of expert assessments obtained an average of 91.25%, which shows that this system is very feasible to use. While the evaluation results of the system implementation showed that 90% of PTTM lecturers were able to understand and skillfully operate the cloud system, thus this system is very feasible to be used as e-monitoring of lecturer performance that is accurate, accountable, objective, and safe to use.
学习课程的讲师对学习课程认证的质量做出了重大贡献，特别是在即将到来的IAPS 4.0完整性中。讲师基础需要通过一个具体的、透明的、结构化的、全面的和负责任的系统来管理。到目前为止，机械工程教育/ PTM研究项目的讲师缺乏数据管理，仍然是无纸化的，因此它的效率较低，效率较低，必须复制文件，并且往往只收集接近研究项目认证的数据。本研究旨在:(1)开发基于云计算系统的教师绩效电子监控产品;(2)了解PTM Study Program中基于云计算系统的电子监控产品对讲师绩效的可行性程度。研究方法采用研究与开发(R&D)，采用ADDIE(分析-设计-开发-实施-评估)模型。研究样本为11名PTM讲师。资格的验证者包括LPM的主席和UST IT团队的主席。使用的工具包括调查表和文件。本研究成功地生产了一种采用平台即服务(PaaS)模式的私有云类型云计算系统形式的产品。用于评估讲师绩效的数据包括治理、人力资源绩效、教育绩效、研究绩效和服务绩效。专家评价结果平均达到91.25%，表明该系统是非常可行的。而系统实施的评估结果显示，90%的PTTM讲师能够理解并熟练操作云系统，因此该系统作为讲师绩效的电子监控是非常可行的，准确、负责、客观、安全。

This research aims at investigating the performance of a gasification stove with wood-chips as fuel and recognizing the factors affecting. The stove consisted of a reactor, a char chamber, and a burner. The fuel was fed into the reactor with a certain amount of primary air was flowed through the bottom part of the reactor, and then was ignited from the topside of the fuel. Meanwhile, combustion zone move down and left char that would be taken out after the process finished. Combustible gases resulted from reactions flowed to the burner where the secondary air enters through holes located at burner side combusted the combustible gases. The highest performance achieve was still relatively low (7.3 %), so that model design improvement is required. The stove performance could be possibly influenced by the following parameters, namely: combustion zone propagation rate, fuel consumption rate, and specific gasification rate, which all of them were very interrelated and indicated temperature stability that was proportional to the efficiency achieved. These were shown by stable water temperature profile obtained from boiling process during gasification. The more stable the process the higher the efficiency.

Risk analysis aims to prevent the incompatibility of a system used in the testing process including the Boiler system. At the Labuan 2 Steam Power Plant (PLTU) 2, the Boiler component was declared "very often" to have a pipe leak. Failure Mode And Effect Analysis (FMEA) is a method used to analyze the risk of failure. This method is represented by calculating the value of RPN (Risk Priority Number) obtained from the results of the multiplication of S (severty), O (occurrence), and D (detection). The highest analysis results are shown at 480 (in the steam drum component in the form of abnormal steam and water level failure). The cause is human error. Next three levels below are (1) Economizer component, which is 360 causes of combustion side ash erosion, material lifetime, and economizer tube fibration; (2) super heater tube and re-heater tube components which are 320 due to Corrosion, Overheat Flyash erosion, Sub blower erosion, Welding error; and (3) Walltube which is 320 causes of overheating and sub blower erosion. The recommendation for the analysis of FMEA testing to predict mantenance is done by applying remaining life assessment after 8,000 hours / operational.
