Abstract

Matematika merupakan salah satu cabang ilmu pengetahuan yang memiliki peranan penting dalam kehidupan manusia. Dari tujuan umum pendidikan matematika, mempelajari matematika tidak hanya menghitung semata, tetapi siswa diharapkan mampu bernalar, berpikir kritis serta logis, dapat memecahkan masalah matematis, masalah dalam bidang ilmu lain serta masalah dalam kehidupan sehari-hari. Artinya salah satu kompetensi yang penting dimiliki siswa adalah kemampuan pemecahan masalah. Dikalangan siswa  sering terjadi  kesulitan dalam mengerjakan soal-soal. Apalagi jika soal tersebut sedikit berbeda dengan contoh yang diberikan atau merupakan pengembangan dari konsep yang diberikan dan membutuhkan penyelesaian yang lebih rumit. Hal tersebut terjadi karena kemampuan pemecahan masalah siswa yang kurang terasah.Penelitian ini bertujuan untuk mengetahui besarnya kemampuan berpikir aljabar siswa dalam matematika, untuk mengetahui besarnya kemampuan pemecahan masalah siswa dalam matematika serta untuk mengetahui besarnya pengaruh kemampuan berpikir aljabar siswa terhadap kemampuan pemecahan masalah siswa dalam matematika. Untuk hipotesis  penelitiannya  yaitu  terdapat  pengaruh  yang  signifikan  antara  kemampuan  berpikir  aljabar  terhadap kemampuan pemecahan masalah matematika siswa. Jenis penelitian ini adalah jenis penelitian kuantitatif, sedangkan metode yang digunakan adalah metode studi kasus. Jumlah populasi terjangkau dalam penelitian ini adalah siswa kelas VIII SMP Negeri 1 Kaliwedi Kabupaten Cirebon yang berjumlah 318 siswa. Teknik pengambilan sampelnya menggunakan teknik cluster random sampling dengan mengambil 1 kelas dari 8 kelas yaitu kelas VIII E dengan jumlah siswa sebanyak 36 siswa.Variabel  dalam  penelitian  ini  adalah  kemampuan  berpikir  aljabar  sebagai variabel  independent  dan kemampuan pemecahan masalah matematika sebagai variabel dependent. Teknik pengumpulan data dalam penelitian ini  menggunakan  tes  pilihan  ganda  untuk  variabel  kemampuan  berpikir  aljabar  dan  tes  uraian  untuk  variabel kemampuan pemecahan masalah matematika. Setelah data diperoleh selanjutnya dilakukan analisis secara deskriptif dan pengujian statistik berupa regresi sederhana. Dari hasil pengolahan data dengan bantuan program SPSS 16.0 diperoleh hasil bahwa kemampuan berpikir aljabar siswa termasuk dalam kategori sedang dengan nilai rata-rata tes62,50 dan simpangan baku 13,706. Untuk kemampuan pemecahan masalah matematikanya memiliki rata-rata 63,06 dan simpangan baku 10,523. Persamaan regresi yang dihasilkan adalah Y = 23,654 + 0,630X dengan nilai koefisien determinasi dalam uji kebaikan model sebesar 67,4%. Hal ini berarti bawa setiap ada peningkatan kemampuan berpikir aljabar, maka akan mempengaruhi kemampuan pemecahan masalah matematika sebesar 0,630. Kata Kunci : Berpikir Aljabar, Pemecahan Masalah

Abstract

Photoaging is caused by exposure to sunlight and ultraviolet radiation (UV-B) through the reactive oxygen species (ROS) molecules formation, resulting in decreased levels of collagen. It is characterized by wrinkles, sagging and rough surfaces. Black cumin has been used in medicine due to its high antioxidant potential. The aim of this study is to identify the effect of black cumin cream on collagen levels and hydration of the skin of Rattus norvegicus exposed to ultraviolet-B rays. This is experimental study in which 30 male Wistar strain rats were classified into 6 sub-groups, namely the KN group (without treatment), KP (getting Nivea cream moisturizer), P1 (basic cream ), P2 (black cumin seed extract cream 0.25%), P3 (cream 0.5%) and P4 (cream 0.75%). P4 rat collagen levels increased significantly before and after the intervention (24 ± 2.23 vs 42.6 ± 14.6, p <0.05).Cream with lower concentrations did not provide a significant increase (p> 0.05). P4 rats also showed increased skin hydration (38.6 ± 19.3 to 63.0 ± 4.47 (p <0.05)), and this was not found in other groups. The administration of topical black cumin seed extract 0.75% can inhibit decreased levels of collagen and increase skin tissue hydration.

Abstract

Background: Most people take self-medication to treat fever without a medical examination. It has the potential medication errors caused by unfair practices. To avoid medication errors, knowledge of fever self-medication among PKK members in Hamlet Bentakan RW 13, Danguran Village, South Klaten District, Klaten Regency, needed to be increased. Methods: The research methodology was descriptive. Thirty-four (34) respondents took action. Before the counseling activity, a pretest was administered to respondents—counseling used leaflet media. A post-test was done after the counseling and training. The pretest and post-test were carried out using a question sheet containing 20 questions about self-medication, health workers guiding self-medication, fever, fever medicine and the proper use of fever medicine. Increased knowledge was calculated by the percentage increase in the number of respondents at the level of certain knowledge categories after counseling. Results: The respondents' knowledge level was in the good and sufficient categories. The level of knowledge in the good category before the counseling was 79.4% respondents, while after the counseling was 97.1% respondents. There was an increase in the level of knowledge in the good category of respondents by 17.7%. In contrast, 20.6% of respondents had sufficient knowledge before the counseling. Respondents with a sufficient level of knowledge reduced after the counseling because the knowledge increased towards good by 6 respondents (17.7% of respondents). The respondent's level of knowledge increased following counseling compared to their knowledge before counseling. Age, education, and occupation all affect one's level of knowledge. Conclusion: Respondents suggested being more selective in choosing and using drugs and asking for complete information from pharmacists or pharmaceutical technical personnel. This counseling is suggested to be carried out regularly in various other villages to reduce errors in self-medication practices.

Abstract

The type of research used is meta-analysis research aimed at determining the level of effectiveness or quality of mind mapping in vocabulary learning, including at elementary, middle, high school, and college levels. This quality was examined using several previous research results that collected data with inclusion and exclusion conditions from the Google Scholar, DOAJ, and Scopus databases. The search results found up to 51 dates that met the requirements with the number of students (N), F-counts, t-counts, and r-counts. The results of data analysis obtained by the simulation software JASP showed that the impact on learning media vocabulary based on mind mapping is 73% significant, which included the High category. The moderator variable is the lowest level of education, the high impact of using mind mapping, namely the college level, with an estimate of the effect of 0.569, Based on the number of participants, the application of mind mapping has more influence on participants totaling more than 30 students with an estimate of 0.928 (strong category), while the lowest effect is seen from the number of participants who collected more than 91 students with an estimate of 0.529, meaning that this mind mapping learning model is most appropriate to be applied in high school rows with more than 30 participants in order to maximize student learning outcomes.
