Abstract

Infant Mortality Rate (IMR) is a key public health indicator reflecting the social, economic, environmental, and healthcare service quality conditions of a population. In 2023, West Java recorded the highest number of infant deaths in Indonesia. These data are count-type in nature and are commonly analyzed using Poisson regression. However, due to the frequent occurrence of overdispersion, the Poisson method becomes less appropriate. As an alternative, the Conway-Maxwell Poisson (CMP) regression is employed, offering greater flexibility in handling violations of the equidispersion assumption. This study aims to apply CMP regression to address overdispersion in the number of infant deaths in West Java Province using the Maximum Likelihood (ML) estimation method. The data used in this study comprise the total number of infant deaths in 2023 across 27 districts and cities in West Java Province. The ML parameter estimation analysis shows that the dispersion parameter values obtained from the CMP and Poisson models are 10.92 and 126.49, respectively. In terms of model evaluation criteria, the CMP model yields an AIC of 402.455 and BIC of 415.41, whereas the Poisson model shows an AIC of 4183.46 and BIC of 4195.12. These results indicate that the CMP model outperforms the Poisson model in handling infant mortality data. Furthermore, four variables are found to be statistically significant in explaining the number of infant deaths in West Java Province, namely the percentage of antenatal care coverage (K4), the number of health facilities by district/city, the percentage of households with clean and healthy living behavior (PHBS), and the percentage of neonatal asphyxia complications, with a significance level of alpha = 5%.

Abstract

The multilevel regression model is a development of the linear regression model that can be used to analyze data that has a hierarchical structure. The problem with this data structure is that individuals in the same group tend to have the same characteristics, so the observations at lower levels are not independent. Education research often produces a hierarchical structure, one of which is PISA data, where students as level-1 nested within schools as level-2. In the PISA 2018 survey, reading literacy is the main focus. The data are sourced from the Organisation for Economic Co-operation and Development (OECD). The survey results show that the reading literacy scores of Indonesian students have decreased, thus placing Indonesia at 74th out of 79 countries. However, it is still very rare to research the reading literacy of Indonesian students' using a multilevel regression model. This study aims to apply a multilevel regression model to determine the factors influencing Indonesian reading literacy scores in PISA 2018 survey data. The results of this study indicate that the factors that influence response variable are gender, grade level, mother's education, facilities at home, age at school entry, student discipline behavior at school, and failing grade, while at the school level are the type of school and school location. The magnitude variance of student reading literacy scores can be explained by the explanatory variables the student level is 11,42% and the school level is 60,66%, while the rest is explained by another factor outside the study.

Abstract

Abstract Kepulauan Seribu has high enrollment rates, namely 99.51% for elementary school, 98.91% for junior high school, and 75.66% for senior high school. The high of enrollment rates needs to be supported by great quality of teachers as educators. Conducting research and writing papers is one way to improve the quality of teachers. Research in education can improve the pedagogic competence and professionalism of teachers and enhance knowledge. In conducting research, statistical analysis is important but many teachers still have problems when it comes to statistical analysis. The One Way ANOVA method is a statistical method used to compare the mean of more than two data groups. This method has been applied in many studies, including research on education. Consider the importance of doing research and writing papers for teachers and how this method can be applied, One Way ANOVA training was carried out in Kepulauan Seribu. Based on the questionnaire before and after the training, the results represented that the training was able to improve the participants' abilities in analysis using the One Way ANOVA. Participants felt they had gained new knowledge, understood the material well, were motivated for further learning, and received new ideas for developing research in education. Abstrak Angka Partisipasi Sekolah di Kepulauan seribu termasuk tinggi yaitu 99,51% untuk jenjang SD, 98,91% untuk jenjang SMP, dan 75,66% untuk jenjang SMA. Tingginya APS perlu diimbangi dengan baiknya kualitas guru sebagai pengajar. Pembuatan karya tulis ilmiah adalah salah satu cara untuk meningkatkan kualitas guru sebagai pendidik. Penelitian dapat meningkatkan kompetensi pedagogik dan profesionalitas guru, serta memperluas cakrawala ilmu pengetahuan. Analisis statistik memegang peranan penting dalam penyusunan penelitian namun masih banyak guru yang terkendala. Metode One Way ANOVA adalah salah satu metode statistika yang digunakan untuk membandingkan lebih dari dua kelompok data. One Way Anova mampu menguji kemampuan dari signifikansi hasil penelitian. Metode ini telah diterapkan pada banyak penelitian termasuk penelitian tentang pendidikan. Melihat pentingnya penulisan karya tulis ilmiah bagi guru serta bagaimana metode One Way ANOVA dapat diterapkan maka dilaksanakan pelatihan One Way ANOVA di Wilayah Kepulauan Seribu. Berdasarkan kuesioner sebelum dan sesudah pelatihan didapatkan hasil bahwa pelatihan One Way Anova ini mampu meningkatkan kemampuan peserta dalam analisis menggunakan metode One Way Anova. Hal ini ditunjukan dengan hasil kuesioner setelah pelatihan yang nilainya lebih tinggi dari pada sebelum pelatihan. Peserta merasa mendapatkan pengetahuan baru, memahami materi dengan baik, termotivasi untuk pembelajaran lanjutan, dan mendapat ide baru untuk pengembangan karya ilmiah.

Abstract

Statistika dan peluang merupakan salah satu materi yang dipelajari dalam pelajaran matematika pada jenjang Sekolah Menengah Pertama. Pentingnya pengetahuan tentang statistika menjadikannya sebagai salah satu materi pada kurikulum. Siswa diharapkan mampu mengolah, menginterpretasi, dan menyajikan data hasil pengamatan. Berdasarkan nilai assesmen nasional siswa nasional didapatkan hasil bahwa persentase siswa yang memenuhi kompetensi minimum pada literasi numerik hanya 32,29% , walaupun memenuhi target nasional namun angka tersebut masih sangat kecil. Diperlukan inovasi pada penyampaian materi matematika khususnya statistika pada jenjang SMP. Penggunaan alat peraga statistika dapat mempermudah siswa dalam memahami statistika terutama dalam penyajian data. Solusi dari permasalahan tersebut adalah menggunakan alat peraga “StatTools” guna meningkatkan kemampuan literasi statistika siswa SMP di Kabupaten Sukabumi. Pelatihan ini diselenggarakan dengan metode ceramah, demonstrasi, dan praktek. Guna mengukur keefektifan dari pelatihan, diberikan kuesioner sebelum dan sesudah pelatihan. Berdasarkan analisis yang dilakukan didapatkan hasil kuesioner setelah pelatihan yang nilainya lebih tinggi dari pada sebelum pelatihan. Peserta merasa mendapatkan pengetahuan baru, memahami materi dengan baik, dan termotivasi untuk pembelajaran lanjutan.

Abstract

Salah satu permasalahan konsep dasar matematika yang ada di sekolah dasar adalah kesulitan dalam memahami konsep (miskonsepsi) materi operasi bilangan, khususnya bilangan pecahan. Oleh karena itu, diperlukan kegiatan kepada masyarakat dalam bentuk pelatihan kepada guru Sekolah Dasar (SD) untuk meningkatkan kompetensi guru sehingga dapat meminimalisir miskonsepsi yang dialami siswa. Pelaksanaan kegiatan dilakukan di wilayah Kota Bekasi dengan bekerja sama dengan mitra KKG Jatiasih Keota Bekasi. Berdasarkan hasil pengamatan guru, masih terdapat banyak miskonsepsi yang ditemui di sekolahnya terkait konsep materi bilangan pecahan dan operasinya.
