PENGEMBANGAN E-LKPD BERBASIS PBL-MR MENGGUNAKAN APLIKASI FLIP BUILDER PADA MATERI BENTUK MOLEKUL DAN INTERAKSI ANTAR MOLEKUL

Molecular shapes and intermolecular interactions materials were quite difficult because it was related to abstract concept that must be presented with multiple representations, so it was necessary to procure PBL-MR (Problem Based Learning-Multiple Representation)-based teaching materials to present this concept in concrete way. This study aimed to develop student e-worksheet based on PBL-MR in molecular shape and intermolecular interactions materials using flip builder application. The method used is Research and Development (R & D), with the Plomp model. This method consisted of three phases, namely (a) preliminary research phase, (b) development phase and (c) assessment phase. Evaluation of the validation was carried out by 3 media experts and 3 material experts. 1-1 test which was assessed by 3 students from the SAF school in Pekanbaru. Small scale with users response to assess practicality by 3 teachers and 30 students from 3 schools, namely MP1, SP2 and SAF in Pekanbaru. The results showed that student e-worksheet was rated very valid with average percentages of material experts 93.83% and media experts 100%; test 1-1 got comments from students and improvement of questions in student e-worksheet; teacher and student responses got average percentages of 95.83% and 84.23% with very practical category. In conclusion, the student e-worksheet was very valid and very practical, so it was suitable for use in chemistry learning.AbstrakMateri bentuk molekul dan interaksi antar molekul tergolong sulit karena terkait dengan konsep abstrak yang harus disajikan dengan multi representasi, sehingga perlu dilakukan pengadaan bahan ajar berbasis PBL-MR (Problem Based Learning-Multiple Representation) untuk menyajikan konsep ini secara konkret. Penelitian ini bertujuan untuk mengembangkan e-LKPD berbasis PBL-MR pada materi bentuk molekul dan interaksi antar molekul menggunakan aplikasi flip builder. Metode yang digunakan adalah Research and Development (R & D), dengan model Plomp. Metode ini terdiri dari tiga fase, yaitu (a) fase penelitian pendahuluan, (b) fase pengembangan dan (c) fase penilaian. Penilaian validasi dilakukan oleh 3 orang ahli media dan 3 orang ahli materi. Uji 1-1 dinilai oleh 3 orang siswa dari sekolah SAF Pekanbaru. Uji skala kecil dengan respon pengguna untuk menilai kepraktisan oleh 3 orang guru dan 30 orang siswa dari 3 sekolah, yaitu MP1, SP2 dan SAF di Pekanbaru. Hasil penelitian menunjukkan bahwa e-LKPD dinilai sangat valid dengan persentase rata-rata ahli materi 93,83% dan ahli media 100%; uji 1-1 mendapatkan komentar siswa dan perbaikan soal dalam e-LKPD; respon guru dan siswa memperoleh persentase rata-rata 95.83% dan 84,23% dengan kategori sangat praktis. Kesimpulannya, e-LKPD yang dikembangkan sangat valid dan sangat praktis sehingga layak digunakan dalam pembelajaran kimia.How To Cite: Wahdatillah, B., Noer, A.M., Anwar, S. L.. (2022).

The Effect of E-Scaffolding in Guided Inquiry Learning on Concept Understanding in Reaction Rate Material

Understanding the concept of an object is needed by students, because the understanding of a concept applies in general so that students can solve more complex problems. This study aims to determine the effect of E-scaffolding in guided inquiry learning on conceptual understanding of reaction rate in class XI IPA MAN 1 Indragiri Hilir E-scaffolding is cognitive assistance in electronic form that given in the guided inquiry learning stage as a cognitive tool to support students. The quasi-experimental research method is used to see the effect of E-scaffolding in guided inquiry learning on conceptual understanding in the control class and the experimental class. The results of the two-way ANOVA hypothesis test with a significance value (0.000) <0.05 indicate that there is a difference in conceptual understanding between the control class and the experimental class. Thus, E-scaffolding can be used as a cognitive assistance for students who have difficulty doing inquiry and cannot be completed independently while in the zone of proximal development (ZPD)

ANALISIS BIAYA LAYANAN RAWAT INAP RUMAH SAKIT MENGGUNAKAN METODE ABC: STUDI KASUS

Rumah Sakit Ibu dan Anak Cempaka Azzahra (RSIA-CA)dalam menetapkan tarif layanan rawat ini masih menggunakan metode komparasi, dimana perhitungan tarif tidak berdasarkan aktivitas aktual tetapi hanya berdasarkan perbandingan dengan rumah sakit lain, sehingga pihak rumah sakit tidak mengetahui tarif sebenarnya selama proses pelayanan pasien, yang secara tidak langsung akan berpengaruh bagi operasional rumah sakit. Tujuan penelitian untuk menghitung biaya satuan pada layanan rawat inap di RSIA-CA menggunakan metode Activity Based Costing (ABC). Adapun jenis penelitian ini yaitu penelitian deskripstif dengan studi kasus, data yang digunakan adalah data primer dengan teknik wawancara dan data sekunder yaitu data aktivitas rawat inap selama tahun 2020 dengan analisis metode ABC. Hasil penelitian menunjukkan untuk fasilitas SVIP, VIP, Kelas 1, dan NICU menghasilkan harga yang sesuai, dimana alokasi biaya mampu menutupi seluruh biaya overhead rawat inap, bahkan harga tersebut telah memberikan keuntungan yang melebihi 30% dari keuntungan yang diharapkan. Untuk kelas 2 dan 3 diperoleh harga yang ditetapkan belum mampu menutupi biaya operasional dan bisa berpotensi menimbulkan kerugian. Sebaiknya manajemen RSIA-CA melakukan perencanaan keuangan yang sesuai terkait penetapan harga dan perencanaan aktivitas operasional pelayanan rawat inap. Hasil penelitian juga diperoleh bahwa perhitungan biaya satuan dengan metode ABC tidak selalu menghasilkan biaya yang lebih murah dari yang ditetapkan, tapi metode ABC sudah lebih baik daripada metode tradisional. Selanjutnya, RSIA-CA dapat melakukan analisis ABC dan ABM pada seluruh pelayanan medis, untuk mengevaluasi sistem penetapan dan keputusan harga, serta meningkatkan mutu manajemen keuangan rumah sakit.

Pengembangan Lembar Kegiatan Peserta Didik (Lkpd) Berbasis Konstruktivisme pada Pokok Bahasan Laju Reaksi

The objective of this research is to develop the student's work sheet on the subject of reaction rate.The research is done in FKIP Riau University. The method of this research is design reserach with the 4-D model which include Define, Design, Develop, and Disseminate. But this research is done until develop. The data research is validation's result of student work sheet based on constructivism on reaction rate.
