Abstract

Science process skills and critical thinking are skills that are very important and must be possessed by students in the 21st century. The purpose of this study is to determine the scientific process and critical thinking skills in terms of gender and see whether there is a relationship between science process skills and critical thinking skills. student. This is because the researcher wants to see a comparison of the abilities of male and female students. This research is a type of quantitative research with a research design. The population of this study were students of SMAN 6 Batanghari and the samples used were students of class A and class B, totaling 80 students with a ratio of 50 female students and 30 male students. The sampling technique used is simple random sampling with the criteria of students who are in Accredited Schools A and Class XII students who have studied the latest direct material. The search instrument used was an observation sheet and a critical reflectance test sheet. The data analysis used is descriptive statistical analysis and deductive analysis. Based on the results obtained, it can be concluded that the science process skills and critical thinking skills of female students are higher than male students. besides that there is a high and positive relationship between students' critical thinking skills and students' critical thinking skills. Based on these results, this research can be useful for teachers, namely so that teachers can carry out learning that can develop and improve science process skills so that students' critical thinking skills can also increase. In addition, the benefits for students themselves are so that students are accustomed to using skills in the learning process and can provide critical solutions in solving problems.

Abstract

PT Akat Srida Amri adalah perusahaan yang bergerak dalam pertambangan batubara dimana proses penambangan akan membuat cekungan saat mengambil material. Pada PT Akat Srida Amri penanganan masalah air belum terlihat maksimal dimana sump yang ada tidak dibuat sesuai dengan masuknya air ke front penambangan serta kapasitas pompa yang digunakan untuk memindahkan air dari sump ke settiling pond tidak sesuai dengan air yang akan dipompa. Oleh karena itu, penelitian ini bertujuan untuk mendesain kolam penampungan (sump) yang sesuai dengan perhitungan air yang masuk ke front penambangan serta pemilihan pompa yang sesuai agar air tidak menggenang dan menganggu aktivitas penambangan. Metode yang dilakukan untuk menentukan desain sump yaitu dengan menghitung data curah hujan selama 10 tahun terakhir yang kemudian akan didispersi, menentukan koefisien limpasan serta luasan catchment area. Setelah dilakukan analisis sesuai metode dispersi, perhitungan J. C. Gumbell, dan perhitungan debit air limpasan maka didapat hasil perhitungan debit air limpasan yang diperkirakan masuk sebesar 15.781,20915 m3/hari, sehingga rekomendasi rencana dimensi sump yang akan dibuat agar dapat menampung sesuai debit air limpasan serta sesuai KEPMEN 1827K/30/MEM/2018 yaitu panjang alas 65,5m, lebar alas 30m, panjang permukaan 81,5m, lebar permukaan 45m dan kedalaman 6m. Untuk penanganan pompa agar bekerja lebih efektif, PT ASARI harus menjadwalkan dan merealisasikan jam kerja pompa selama 10 jam perhari, meletakkan atau menanam tiang pengukur air di dalam sump, serta dapat juga melakukan penambahan engine pada mesin pompa agar kekuatan daya pompa dapat lebih tinggi lagi.
