Abstract

This paper is the result of first phase of the research about the development of students’ mathematical understanding and representation ability through Joyful Problem-based Learning (JPBL) at Public Junior High School in North Sumatera, Indonesia. The population is all of the students of public junior high school (PJHS) in North Sumatera. Samples choose based on stratified random sampling. The samples are the students of PJHS 27 Medan, PJHS 1 Percut Sei Tuan, PJHS 1 Tebing Tinggi, and PJHS 2 Pematangsiantar. The techniques used for collecting data is observation, interview, and essay test. The research findings: (1) Based on interview and observation found that conventional approach still use in all of the class of PJHS; The students engagement in learning activity is very low as well as students self-regulated learning; Most of the students do not attain minimal mastery achievement, (2) Based on essay test found that achievement of the students in mathematical understanding and representation test is categories low.Keywords: mathematical understanding, mathematical representation, joyful problem-based learning DOI: http://dx.doi.org/10.22342/jme.7.1.2816.43-56

Abstract

Penelitian ini bertujuan untuk memperoleh perangkat pembelajaran berbasis discovery learning berbantuan Microsoft Excel yang efektif dalam meningkattkan kemampuan pemecahan masalah statistika (KPMS)  dan soft skills siswa SMP. Kriteria efektif bersandar pada teori intervensi pembelajaran yang meliputi adanya peningkatan capaian hasil belajar setelah intervensi, adanya respon positif siswa dan guru terhadap perangkat pembelajaran yang dikembangkan, keterlibatan (engagement) siswa yang tinggi dalam pembelajaran,  serta diperoleh lebih dari 65% siswa mencapai skor 65 dari skala 100 dalam tes KPMS. Peningkatan KPMS diselidiki melalui indeks gain ternormalisasi. Peningkatan soft skills dideskripsikan dengan bersandar pada statistik deskriptik. Penelitian ini menghasilkan perangkat pembelajaran yang memiliki karakteristik efektif dalam meningkatkan KPMS dan soft skills siswa SMP sehingga siap untuk disebarluaskan. Disarankan agar guru lebih diberi kesempatan untuk mengimplementasikan perangkat pembelajaran yang dikembangkan sesuai dengan tujuan pembelajaran matematika sehingga dapat diharapkan siswa memperoleh kemampuan pemecahan masalah dan soft skills yang lebih tinggi lagi.This study aims to obtain discovery learning-based learning tools supported by Microsoft Excel that are effective in increasing statistical problem solving abilities (KPMS) and soft skills of junior high school students. Effective criteria rely on the theory of learning interventions which include an increase in learning outcomes after the intervention, positive student and teacher responses to the learning tools developed, high student engagement in learning, and obtained more than 65% of students achieving a score of 65 from a scale of 100 in the KPMS test. The increase in KPMS is investigated through a normalized gain index. Improved soft skills are described by relying on descriptive statistics. This research produces learning tools that have effective characteristics in improving problem solving skills and soft skills of junior high school students so that they are ready to be disseminated. It is recommended that teachers be given more opportunities to implement learning tools that are developed in accordance with the learning objectives of mathematics so that students can expect to get higher problem solving skills and soft skills.

Abstract

Stunting is an increasingly common problem in developing countries, including Indonesia. In Cirebon Regency, especially in Ciledug District, stunting cases amounted to 13.6% in 2018. The magnitude of the benefits of breastfeeding is not offset by an increase in breastfeeding behavior. According to WHO, more than 40% of babies are introduced too early to complementary foods. One way to increase production is oxytocin massage. Oxytocin massage is performed to stimulate the oxitocin reflex or letdown reflex. The increase in the number of breastfeeding mothers globally has the potential to save the lives of more than 820,000 children under five years old and could prevent an additional 20,000 cases of breast cancer in women each year. This study used the pre-experiment method using one group pretest-post test design, a design experiment that uses one group of subjects and takes measurements before and after giving treatment to subjects. The milk production of postpartum mothers before oxytocin massage has an average of 23.10 ml, while after oxytocin massage the milk production of postpartum mothers has an average of 61.43 ml. The paired sample T test results were obtained significantly by 0.000 (p-value < 0.05). The results of the study found that there was an effect of oxytocin massage on breast milk production. There is a difference in milk production before and after oxytocin massage. It is expected to be able to apply the implementation of oxytocin massage to postpartum mothers in health services.

Abstract

Emotional intelligence has become an important part of achieving learning outcomes and has been proven by previous research. Self-awareness is part of emotional intelligence. Self-awareness student must be managed because it will contribute to the understanding of the student learning outcomes. So students can compete in facing a dynamic environment. This research study was to collect data and insights about student learning outcomes based on the level of self-awareness. The hypothesis of this study is that students who achieve good learning outcomes are students who have good self-awareness and have a positive influence on student learning outcomes. The research sample consisted of 30 students of Sriwijaya State Polytechnic, Bukit class and 11 students of Sriwijaya State Polytechnic, Banyuasin Class. Self-awareness and student learning outcomes were measured by a questionnaire with a Lickert scale. Then, the data were analyzed through SPSS software. The result is that self-awareness has a significant influence on student learning outcomes.

Abstract

Kelelahan kerja merupakan kondisi dimana seseorang sudah tidak mampu lagi melalukan aktivitas kerjanya. Kelelahan keraj dapat terjadi karena adanya pengaruh dari lingkungan kerja yang tidak menunjang. Tujuan dari penelitian ini adalah untuk mengetahui hubungan pencahayaan serta karakteristik individu (umur, beban kerja dan status gizi) dengan kelelahan kerja pada pekerja bagian underground di PT.Antam Bogor. Metode penelitian ini adalah penelitian kuantitatif dengan desain penelitian menggunakan cross sectional. Populasi penelitian sebanyak 200 orang dan teknik pengambilan sampel menggunakan purposive sampling dengan jumlah sampel penelitian sebesar 67 responden. Pengukuran pencahayaan menggunakan alat lux meter dan pengumpulan data pekerja dilakukan dengan menggunakan kuesioner IFRC. Analisis data penelitian menggunakan aplikasi statistik dengan menggunakan uji statistik chi-square. Hasil analisis menunjukkan ada hubungan antara umur (p-value=0,044) OR sebesar 3,147 dan beban kerja (p-value=0,032) OR sebesar 3,407 dan tidak adanya hubungan antara pencahayaan (p-value=0,937) dan status gizi (p-value=0,601) dengan kelelahan kerja. Kesimpulan dari penelitian ini adalah tidak adanya hubungan pencahayaan dengan kelelahan kerja. Peneliti ini menyarankan kepada perusahaan untuk memperhatikan kondisi pencahayaan diruangan kerja agar tidak menimbulkan risiko terjadinya kelelahan kerja
