Abstract

purpose of this research is to determine the effect of flipped classroom size on students' critical thinking abilities. This type of research is meta-analysis. The data source comes from an analysis of 12 national and international journals published in 2018-2023. Data source search process via Google Scholar; ERIC, ScienceDirect, Wiley; ProQuest, DOAJ and EBSCO. Data selection using the PRISMA method consists of identification, screening, eligibility and inclusion. These findings conclude that the flipped classroom has a positive influence on students' critical thinking skills with a summary effect size value ( rRE= 0.799). The flipped classroom has a moderate influence on students' critical thinking abilities at school

Abstract

Ketel uap di kapal merupakan salah satu permesinan bantu yang mempunyai peran penting dalam menghasilkan uap panas yang berkualitas. Uap tersebut digunakan untuk memanaskan bahan bakar, minyak lumas, ruangan, air pada akomodasi dan kebutuhan lainnya. Untuk menghasilkan uap yang berkualitas dalam jumlah banyak, diperlukan pembakaran yang sempurna pada ketel uap bantu. Pentingnya kinerja ketel uap tersebut, maka peneliti mengambil judul: Analisis Komprehensif Gagalnya Pembakaran Pada Boiler Di Kapal MT Gas Kalimantan. Penelitian dilaksanakan di kapal MT Gas Kalimantan. Sumber data yang diperoleh adalah data primer yang didapatkan langsung dari tempat penelitian, serta data sekunder yang didapatkan dari literatur-literatur yang berkaitan dengan judul berkaitan. Berdasarkan hasil analisis diperoleh kesimpulan bahawa gagalnya pembakaran pada ketel uap disebabkan oleh tersumbatnya Nozzle tip oleh kotoran, serta diakibatkan oleh kotornya filter nozzle pada burner. Upaya yang dilakukan agar pembakaran boiler dapat bekerja dengan baik adalah dengan melakukan perawatan secara teratur, serta dilakukan overhaul atau pembongkaran boiler, penggantian packing burner, membersihkan nozzle, serta penyetelan electrode sebagai langkah perbaikan pada ruang bakar ketel uap.

Abstract

EVALUATION OF GENERAL TERMINAL OPERATIONAL PERFORMANCE IN GRESIK PORTAn increase in the number of ship visits and the flow of goods at the Gresik Port Public Terminal can cause long ship berthing queues. Therefore, it is necessary to conduct research to determine the operational performance of the Gresik Port General Terminal as an evaluation and consideration material in policy making. In this study, we will discuss the operational performance of the Gresik Port General Terminal based on the Regulation of the Director General of Sea Transportation Number: HK.103/2/18/DJPL-16, then compare it with the perception of service users using the IPA (Importance Performance Analysis) method. From the results of the analysis based on the Regulation of the Director General of Sea Transportation Number: HK.103/2/18/DJPL-16, it was found that the operational performance indicators of the Gresik Port General Terminal which had a poor level of performance were Waiting Time (WT) with a percentage of achievement of 349.5%, a comparison of effective time compared to berthing time (ET: BT) with a percentage of achievement of 83.93%, and dry bulk productivity with a percentage of achievement of 74.89%. Meanwhile, from the results of the analysis using the IPA (Importance Performance Analysis) method, it was found that the operational performance indicators of the Gresik Port General Terminal that had poor performance were: waiting time pilot, waiting time ship, berthing time, berthing service berthing Pelra, productivity loading and unloading general cargo, productivity loading and unloading bag cargo, productivity loading and unloading dry bulk, length / number of docks, berthing occupancy ratio (BOR), fender condition and depth of the Port pool. Peningkatan jumlah kunjungan kapal dan arus barang di Terminal Umum Pelabuhan Gresik dapat menimbulkan antrian sandar kapal yang lama. Oleh karena itu perlu dilakukan penelitian untuk mengetahui kinerja operasional Terminal Umum Pelabuhan Gresik sebagai bahan evaluasi dan pertimbangan dalam pengambilan kebijakan. Pada penelitian ini, akan membahas kinerja operasional Terminal Umum Pelabuhan Gresik berdasarkan Peraturan Direktur Jenderal Perhubungan Laut Nomor : HK.103/2/18/DJPL-16, kemudian membandingkannya dengan persepsi pengguna jasa menggunakan metode IPA (Importance Performance Analysis). Dari hasil analisa berdasarkan Peraturan Direktur Jenderal Perhubungan Laut Nomor : HK.103/2/18/DJPL-16 didapatkan bahwa indikator kinerja operasional Terminal Umum Pelabuhan Gresik dengan kinerja kurang baik yaitu Waiting Time (WT), perbandingan effective time dibanding berthing time (ET : BT), dan produktivitas curah kering. Sedangkan dari hasil analisa menggunakan metode IPA (Importance Performance Analysis) didapatkan bahwa indikator kinerja operasional Terminal Umum Pelabuhan Gresik dengan kinerja kurang baik yaitu : waiting time pilot, waiting time ship, berthing time, pelayanan sandar kapal Pelra, produktivitas bongkar muat general cargo, produktivitas bongkar muat bag cargo, produktivitas bongkar muat curah kering, panjang/jumlah dermaga, berthing occupancy ratio (BOR), kondisi fender dan kedalaman kolam pelabuhan.

Abstract

This study aims to examine the use of beach sand as an alternative material for fine aggregate in normal concrete of K-225 quality with the addition of silica fume. The method used is an experimental method by testing compressive strength and slump values. In this study, 4 types of test pieces were used, namely concrete mixture using river sand (BN), concrete mixture using beach sand (BPP), concrete mixture using beach sand with the addition of 10% silica fume (BPPSF10), and concrete mixture using beach sand with the addition of silica fume 20% (BPPSF20). Based on the test results, it can be concluded that the concrete mixture using beach sand (BPP, BPPSF10 and BPPSF20) has a lower compressive strength than the concrete mixture using river sand. The addition of silica fume to the beach sand concrete mixture by 10% and 20% can increase the compressive strength of concrete but has not been able to achieve the planned compressive strength. Meanwhile, the slump value in the concrete mixture using beach sand is lower than the slump value of the concrete mixture using river sand.
