Abstract

The students of the Matholiul Anwar Islamic boarding school come from various different regions so that they have quite diverse social and economic backgrounds. Likewise with learning motivation, achievement motivation and student learning achievement are also diverse. This study aims to determine the effect of the social and economic background of students on achievement motivation, learning motivation and learning achievement. The research sample used was 49 students in the F dormitory of the Matholiul Anwar Sukodadi Lamongan Islamic boarding school. This study uses the Multivariate Regression Analysis model. From the results of the partial study, the effect of social status on the dependent variable was concluded that there was an effect of social status on achievement motivation, learning motivation and learning achievement. Meanwhile, for the variable of economic status on the dependent variable, it can be concluded that there is no effect of economic status on achievement motivation, learning motivation, and learning achievement. Simultaneously, it was obtained that the background of the students affected the achievement motivation, learning motivation, and learning achievement in the F dormitory of the Matholiul Anwar Islamic boarding school.

Abstract

Kernel adjusted density estimation is a modification of the regular kernel density estimation. The modification is applied to a kernel function. This kernel function is derived from the location-scale transformation. Simulation study shows that this estimation have better results than the regular estimation because it has smaller MSE value. In addition, if normal kernel is used as a kernel function then the curve estimation will be smoother than other kernel function such as uniform kernel and Epachenikov kernel.

Abstract

Nadaraya Watson's kernel adjusted regression estimator is an estimator whose kernel is taken from the family of scale-location associated with the classical kernel density estimator. Based on these estimator, it can be obtained optimal bandwith and scale parameter. This estimator gives a better estimation results compared with Naradaya Watson's classical kernel regression estimator. This is proven by the small grade MSE which is given by this estimator.

Abstract

This activity aims to assist students learning to count who are still experiencing difficulties at Ngimbang State Elementary School. Mastery of mathematical calculations at a basic level is very important as an effort to build a strong foundation in understanding basic mathematics. This community service uses the singing method. The results of this service were attended by 30 grade 1 students, with 20 students able to count well and 10 students who were still lacking. This mentoring activity was carried out well. Students were very enthusiastic about following it. This service is a community service that aims to improve the numeracy skills of grade 1 students through the use of singing as a fun and interactive learning approach. It can be seen that grade 1 students who previously had absolutely no understanding of counting, have now made significant progress. The use of singing media is a very effective and exciting learning method for improving numeracy skills for elementary school students.

Abstract

Performance not only a source of pride for students, but also for schools. The Indonesian Student Research Olympiad (OPSI) is a national-level activity recognized by the National Achievement Center (PUSPRESNAS). Schools need to provide guidance to support their students in participating in OPSI competitions, one of which is in mathematics. The purpose of this community service is to provide new learning experiences to students at SMA Negeri 1 Mirit, Kebumen Regency, in managing real-world problems and using mathematics to find solutions. Examples given are the problem of medication timing and radioactive decay. The community service method consists of material presentation, class discussions, and providing examples of problems that can be solved using similar methods. The community service is carried out once for 2 hours, the results of the community service are measured by a questionnaire, and of the 20 students who participated in the activity, all agreed that this community service provided a new learning experience that was different from the learning experience during the lessons.

Abstract

Analisis cluster merupakan salah satu teknik interdependensi yang dapat menggambarkan kedekatan jarak atau kemiripan antara objek dan variabel. Analisis cluster terbagi atas dua metode, yaitu hirarki dan nonhirarki. Dalam penelitian ini menggunakan analisis cluster hirarki dengan metode average linkage. Metode ini diterapkan dalam pengelompokan kabupaten/kota di Provinsi Jawa Timur berdasarkan faktor-faktor kemiskinan. Dari 38 kabupaten/kota di Provinsi Jawa Timur diperoleh hasil metode average linkage sebanyak 3 kelompok, yaitu kelompok tingkat rendah, kelompok tingkat sedang, dan kelompok tingkat tinggi. Kelompok yang terbentuk di antaranya, kelompok tingkat rendah terdiri dari Kabupaten/kota Pacitan, Ponorogo, Trenggalek, Tulungagung, Blitar, Kediri, Malang, Lumajang, Jember, Banyuwangi, Bondowoso, Situbondo, Probolinggo, Pasuruan, Sidoarjo, Jombang, Madiun, Magetan, Ngawi, Bojonegoro, Tuban, Gresik, Sumenep, Kota Kediri, Kota Blitar, Kota Malang, Kota Probolinggo, Kota Pasuruan, Kota Madiun, Kota Surabaya dan Kota Batu.

Abstract

The Covid-19 pandemic has resulted in a change in the face-to-face learning process to online learning. But in the process, online learning is not always easy to do. Some of the problems in the implementation of learning from the internet network are not evenly distributed, the decrease in understanding ability and student learning outcomes, and also student saturation during the learning process. To overcome this, we need an online learning media based on gamification. Gamification is a learning process that is integrated with game design. This study aims to develop gamification-based online learning using Moodle media. The method used in this research is the research and development method. This research and development use the ADDIE model. The results of the validation test carried out by the validator developed were declared very valid, with a percentage of 87.5% by material validators and 93.75% by media validators. Based on the feasibility test that has been carried out, it is obtained a percentage of 90.5% with a feasible category. From the series of validation tests and trials, it can be stated that overall, the learning media developed are very valid and very suitable for use in online learning.
