Abstract

Based on the result of pre survey in SMP N 7 Metro, that is to be presented problem in this research namely: “There are many students at the VII grade that was not successful yet in their integrated social sciences learning outcomes at the odd semester SMP Negeri 7 Metro in academic year 2017/2018”. Based on the problem above, the problem formulation in this research is: Is there any influence of using Cooperative Learning Model Type Student Facilitator and Explaining (SFE) toward the Integrated Social Sciences Learning Outcomes of the students at the VII grade even semester SMP Negeri 7 Metro in Academic Year 2017/2018?. Based on the result of research data analysis used simple linier regression formula, it was found that a = b = . So, Ŷ = a + bXis . Then, it proved that there is a positive influence of using Cooperative Learning Model Type Student Facilitator and Explaining (SFE) toward the Integrated Social Sciences Learning Outcomes in SMP Negeri 7 Metro in Academic Year 2017/2018. It was proved by the calculation of data analysis that showed tobserved was higher than ttable (thitung>ttabel) in significance level of 5% was3,08> 1,71and in significance level of 1% was3,08>2,48. Therefore, the hypothesis is accepted that means there is a positive influence of using Cooperative Learning Model Type Student Facilitator and Explaining (SFE) toward the Integrated Social Sciences Learning Outcomes in SMP Negeri 7. Keywords: Learning Model Type Student Facilitator and Explaining (SFE), Learning Outcomes

Abstract

Penelitian ini merupakan penelitian Quasi eksperimen dengan menggunakan pendekatan kuantitatif karena peneliti tidak merubah keadaan kelompok awal sampel. Desain penelitian dalam ini yaitu “the nonequivalent posttest-only control group design”. Penelitian ini dilaksanakan di Sekolah Menengah Pertama (SMP) Tulang Bawang Barat Provinsi Lampung. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII di SMP Tulang Bawang Barat. Pendekatan Contextual Teaching and Learning (CTL) merupakan konsep belajar yang membantu guru mengaitkan antara materi yang diajarkan dengan situasi dunia nyata siswa, dan mendorong siswa membuat hubungan antara pengetahuan yang dimilikinya dengan penerapannya dalam kehidupan mereka sehari-hari. Berpikir kritis merupakan kemampuan untuk memahami masalah, menyeleksi informasi yang penting untuk menyelasaikan masalah, memahami asumsi-asumsi, merumuskan dan menyelasaikan hipotesis yang relevan, serta menarik kesimpulan yang valid dan menentukan kevalidan dari kesimpulan-kesimpulan. Berdasarkan peneliitian yang telah dilakukan dan berdasarkan hasil uji perbedaan rataan postes kelas eksperimen dan kelas kontrol tersebut diketahui bahwa nilai Sig. (2-tailed) yaitu 0,038 lebih kecil dari nilai α = 0,05, sehingga H0 ditolak. Hasil ini berarti kedua kelas memiliki kemampuan berpikir kritis yang berbeda secara signifikan. Kemampuan berpikir kritis siswa yang mendapat pembelajaran pendekatan Contextual Teaching and Learning (CTL)  lebih tinggi  dari pada siswa yang mendapat pembelajaran konvensional. Sehingga dapat disimpulkan bahwa terdapat pengaruh pendekatan Contextual Teaching and Learning (CTL) terhadap berpikir kritis siswa pada mata pelajaran ekonomi.

Abstract

Think Pair Share model is one of the cooperative learning method with syntax: think, pair, sharing answer and opinion that are able to change the assumption that the recitation method and the discussion that need to be organized in the setting of the whole group. This research aim to know the influence of using think pair share model for the student’s learning outcome of economic studies at SMA Negeri 1 Punggur that involved 126 students of 4 class at grade XI year 2018/2019. There are 32 students from XI IPS4 as sample and 31 students from XI IPS3 as control class. The instrument data collection retrieved by multiple choice test of 20 questions with 4 alternative options a-b-c-d. The questions is given to the students who have been given the experiment treatment and within treatment by the X variable. The results are proven by the analyze of thitung > ttabel , on the list of signification 5% i.e. 3.24 > 1.68 and at the significant level 1% i.e. 3.24 > 2.42. The conclusion of the hypothesis: there is positive influence by using cooperative learning think pair share model to increase the student’s learning outcome of economic studies at SMA Negeri 1 Punggur class XI IPS. Students who were declare pass with KKM=75 after being given the treatment as many as 26 and the students or as much as 81.25%, and the students who not pass as many as 6 peoples or 18.75%. Well then, the learning process can be said to be successful. Keyword: think pair share, learning outcome

Abstract

A diesel Generator is equipment has functions as a power generator and electricity supply. Tanker warship is oneof the navy warships applying diesel generator Cummins KTA 38D for electricity supply when going on missionarea or at basecamp. On diesel generator system consists of 7 (seven) sub-system are coolant sub-system,seawater cooling sub-system, fuel oil sub-system, air intake and exhaust sub-system, Lub oil sub-system, Electricstarter sub-system and controlling sub-system. Due high operating hours, the potential for damage is increasing,because damage a component diesel generator. According ship damage report data, the percentage damage ofdiesel generator reach until 38.5% from total equipment damage that occurred during 2016-2022 year. Based onthat phenomena, this research will identifcation factors that cause damage and determine the components havehigh criticality in the diesel generator using the FTA (Fault Tree Analysis) to systematically explain unexpectedcausal factors that lead to failure, and the FMECA (Failure Mode Effect And Criticality Analysis) method to identifycritical components according factors have the highest critical point with calculation of the Risk Priority Number(RPN). The results of calculations and analysis using the FTA and FMECA methods, there are 6 (six) criticalcomponents with the highest RPN value in the diesel generator system, that Tube sea water component (375,4)with the risk of leaking, Impeller components (377,1) with a risk of corrosion/crack, Body Cover SW (372,0) witha risk of corrosion, Mechanical Seals (369,8) with a risk of leaking/damage, strainer (369,1) component with a riskof corrosion, Rectangular seal HE (367,9) a risk leakage and Battery (371,0) with a risk no power electric for startengine.Keywords: Diesel generator, FTA, FMECA, Critical components

Abstract

The Cummins KTA 38D brand diesel generator is a ship's power generation equipment owned by a supplier to warship electrical needs both at base or in operation. Based on damage report data from 2016 - 2022, the percentage of diesel generator damage reached 38.5% of the total damage to all ship equipment. The results of the analysis using the FTA method cause the failure of the diesel generator to be caused by one of the failure factors in the supporting sub-systems,both from the electrical sub-system, fuel sub-system, air sub-system, fresh water sub-system, seawater sub-system, the lubricant sub-system and the control sub-system were damaged. Calculation using FMECA, there are five critical components based on the RPN value with a "high" risk rating, namely the Body Cover Pump component with the risk of corrosion (205), the Impeller component with the risk of corrosion/cracking (260.5), the Cooler tube component with the risk of leakage (264,7), Mechanical Seal component with risk of damage/leak (192.8), Rectanguler Seal component with risk of leak (196). With a reliability approach and analysis of total cost replacement age preventive maintenance with a minimum reliability limit of 55.84%. It can be proposed maintenance intervals for Body Cover Pump components at 980 running hours with an increase in reliability of 30.87% and maintenance cost savings reaching 14.57%, Impeller components at 1581 running hours with an increase in reliability of 35.79% and maintenance cost savings reaching 29.28%, Cooler tube components at 979 running hours with an increase in reliability of 26.06% and maintenance cost savings reaching 16.40%, mechanical seal components at 1290 running hours with an increase in reliability of 33,20% and savings in maintenance costs reaching 22,57%, the rechtangular seal component on 979 running hours with an increase in reliability of 31.67% and savings in maintenance costs reaching 38.88%.
