Abstract

This study aims to analyze the learning outcome of mathematics and sciences in the Indonesian National Examination from 2015 to 2018 of MTs (Islamic secondary school). The results of the analysis are used as the basis for making alternative policy as a possible way to improve the quality of mathematics and science learning. With the sample size of 360, 371 MTs students in East Java, the achievement was measured by using 40 multiple choice questions with each having four answer options. Split-plot and latent profile analysis of the data show that there was a consistent decrease in the achievement of mathematics and sciences of the moderate group of MTs from 2015 to 2018 with a dramatic drop in mathematics and tendency to drop for science. The fundamental implication of these findings is that there is a need for learning innovations to improve mathematics and science learning outcomes for 21st century learning. The findings can also provide data support for decision making for the revision of the mathematics and science curriculum and can be further used as empirical evidence for the developed countries in finding ways to improve the quality of mathematics and science learning outcomes for 21st century learning, in particular, to assist the developing countries such as Indonesia.

Abstract

Abstract: The objectives of the research are to examine: (1) the relationship between parents? education level as an indicator of socioeconomic status (SES) with students? mathematics achievement, and (2) the interaction between parents? education level and the intensity of parental involvement in predicting students? mathematics achievement. The sample (N=2,867) was selected through stratified random sampling of Indonesian high school National Examination (NE) test takers in 2016. The sampling was based on careful consideration of the representativeness and the distribution of provinces, gender, type of school (general-vocational), and school status (public-private). Data was analyzed using parallel multiple mediator analyses. The findings highlight that: (1) compared to fathers, mothers? education level had a stronger contribution to students? achievement in mathematics, and (2) mothers? involvement mediated the relationship between mothers? level of education and students? mathematics achievement. However, more intensive parental involvement was associated with lower mathematics achievement. Keywords: SES, mathematics, parents? education levels, involvement  STATUS SOSIAL EKONOMI, KETERLIBATAN ORANGTUA DALAM BELAJAR DAN HASIL BELAJAR MATEMATIKA SISWA SMA DI INDONESIA Abstrak: Penelitian ini bertujuan untuk menguji: (1) kaitan antara tingkat pendidikan orangtua sebagai indikator  status sosial ekonomi (SSE) dengan  hasil belajar matematika siswa, dan (2) interaksi antara tingkat pendidikan orangtua dengan intensitas keterlibatan orangtua dalam memprediksi hasil belajar matematika anak-anaknya.  Sampel penelitian ini (N=2,867) dipilih secara stratified random sampling dari peserta Ujian Nasional di Indonesia tahun 2016 jenjang SMA. Pengambilan sampel didasarkan pada keterwakilan dan sebaran provinsi, jenis kelamin, jenis sekolah (SMA/MA atau SMK) dan status sekolah (negeri-swasta). Data dianalisis dengan menggunakan analisis parallel multiple mediator. Hasil penelitian menunjukkan: (1) pendidikan ibu memiliki peran sangat penting karena sangat berkonstribusi dalam menunjang hasil belajar matematika anaknya dibandingkan pendidikan ayah, dan (2) keterlibatan ibu dalam belajar anak yang dimediasi tingkat pendidikannya berpengaruh terhadap hasil belajar matematika anaknya. Namun demikian, keterlibatan orangtua yang terlalu intens dalam kegiatan belajar anak justru berdampak kurang baik terhadap hasil belajar matematika anaknya. Kata Kunci: SSE, matematika, tingkat pendidikan orangtua, keterlibatan

Abstract

Terjadinya resistensi antibiotik menjadi permasalahan dalam dunia kesehatan. Peningkatan kemampuan patogen dalam menahan efek obat menyebabkan timbulnya resistensi. Beberapa bakteri patogen pada manusia dilaporkan telah mengalami resistensi terhadap lebih dari satu kelas antibiotik. Untuk mengatasi permasalahan tersebut, maka perlu dilakukan pencarian senyawa antibiotik baru yang lebih efektif dalam mengatasi permasalahan bakteri Multi-drug Resistant (MDR). Metabolit sekunder yang diproduksi oleh invertebrata laut  mempunyai prospek sebagai bahan obat dari laut. Nudibranch diduga mampu menghasilkan metabolit sekunder sebagai mekanisme pertahanan diri. Tujuan dari penelitian ini adalah untuk mengetahui fraksi dari ekstrak nudibranch Jorunna funebris yang menunjukkan bioaktivitas terhadap bakteri Multi-drug Resistant (MDR). Proses ekstraksi dilakukan dengan metode maserasi. Fraksinasi dengan Kromatografi Kolom Terbuka (KKT). Uji aktivitas antibakteri menggunakan metode difusi agar. Analisis komponen senyawa dengan GC-MS. Hasil penelitian menunjukkan bahwa 8 fraksi ekstrak nudibranch J. funebris menunjukkan aktivitas antibakteri. Hasil uji aktivitas menunjukkan fraksi I paling aktif terhadap 5 bakteri uji yaitu Klebsiella, Pseudomonas, Escherichia coli, Enterobacter 5 dan Enterobacter 10 dengan rata-rata zona hambatan secara berurutan sebesar 12,78 mm; 12,51 mm; 15,47 mm; 14,09 mm dan 12,46 mm. Fraksi II paling aktif terhadap bakteri Coagulase Negative Staphylococcus dengan rata-rata zona hambatan sebesar 12,70 mm. Analisis GC-MS menunjukkan bahwa dalam fraksi II terdapat senyawa 1-oktadekanol yang berpotensi sebagai antibakteri. Kata kunci : nudibranch, Jorunna funebris, antibakteri, multi-drug resistant, 1-oktadekanol Emergence of antibiotic resistance become a problems on medical world. Increasing pathogen ability to hold the antibiotic effect caused resistance. Several human-patogen bacteria were resistance to one or more classes of antibiotics.

Abstract

When a unidimensionality assumption has been actually violated, interpretation of test scores might be jeopardized. It couldn’t be overemphasized in case of high-stake exams such as PAPs UGM (academic potentiality test for UGM graduate student candidates) which was supposed to reflect a composite ability. This study aimed at revealing item characteristics of PAPs A-1 Series based on UIRT and MIRT and discovering dimensionality of the three subtests of the test. Scores of subject (n=2035) on the 3 subtests were analysed and the results showed that 27 items (10 of Verbal, 8 of Kuantitatif, and 9 of Penalaran) were flagged for having rbis of less than 0.25 and 6 other items for having abnormally high pseudo-guessing parameters. Dimensionality analyses found out that Penalaran subtest was local-dependent while Verbal and Kuantitatif subtests both were local-independent. In addition, MIRT analyses failed to fully describe item characteristics of the test due to effect of interaction among probabilities of correct response of the three subtests. Keywords: dimensionality, PAPs UGM, MIRT, UIRT

Abstract

The purpose of this paper is to find out the relationship between the Qur'an and Culture and how to become a good Muslim based on the values ??of the Qur'an and Culture. The research method used is qualitative in the form of library studies. Data is collected by researching books and journals and other sources that support research activities. The results of this study are that Islam is not born of cultural products. However, it builds a culture, a civilization. A civilization based on the Qur'an and the Sunnah of the Prophet. that is finally called Islamic civilization. With this, we can begin to put Islam in our daily lives. Building Islamic culture with a foundation of concepts derived from Islam with its source is the Qur'an. The life of a Muslim must be following the rules set by the Qur'an. Muslims must be able and reluctant (upholding) to uphold a culture that is a local identity in themselves with the foundation of the holy values ??contained in the Qur'an. Among them is a sincere, knowledgeable and honest attitude to be a Muslim person in undergoing a time struggle that continues to change along with changing patterns of human civilization. Thus, there is no reason for a Muslim to lose his cultural identity to become a good Muslim. Because Al-Qur'an and Culture are clothes that are suitable to be worn by every Muslim in every fragment of life rites
