Abstract

The research location is in Gorontalo City. The location is an area that has geological structural conditions of high complexity. The study used statistical analysis of the robustness data to determine the direction of the firmness and the RQD (rock quality designation) value. The research objectives consist of two, namely knowing the direction of the stress (the main force of tectonic formation) and knowing the RQD value based on the analysis of joint data. To achieve these two objectives, it is carried out with a research method in the form of an inductive method. This method combines the results of a literature review, previous research and field data, all of which are comprehensively studied, analyzed, and synthesized. Statistical analysis (fan diagram) on joint data on granite rocks in Gorontalo City. The results and discussion resulted in the direction of maximum stress (Ï„1) = N 15oE and the direction of minimum stress (Ï„3) = N 75oW. The rock RQD value is 40.60% so that the rock quality in this research area is classified as moderate. The results of the measurement of the joint spacing at this station are obtained from a distance of (5-10) cm, so it is included in the weak scale so that the joint space strongly supports the occurrence of landslides.

Abstract

In time series data research, it is often encountered the problem of lack of available time and budget. So often found the presence of censored data. Censored data can be analyzed using the partial likelihood method. However, other obstacles will arise if the processed data contains ties. So it is necessary to use other methods that can overcome the co-occurrence. In this study, the Breslow method is used to estimate the censored data due to joint events. This method is applied to the case of patients with burns. The variables used are the method of treatment, gender, race and type of burn. The results of the analysis showed that race did not give a significant difference to the incidence of cutting burned organs. While the other three variables showed significant differences at the 95% confidence level. The results of the analysis using the Cox proportional hazard method showed that patients treated with the body cleansing method had 17% greater risk of cutting than those treated with the body routhine bathing.

Abstract

Penelitian ini memiliki tujuan guna untuk melihat pengaruh multimedia interaktif terhadap hasil belajar peserta didik pada materi sistem koordinat. Penelitian ini adalah penelitian eksperimen dengan subjek penelitian yang diklasifikasikan menjadi dua yakni VIII-A selaku kelas eksperimen serta VIII-B selaku kelas kontrol pada populasi MTs Negeri 2 Bolaang Mongondow Utara. Dengan desain penelitian pre-test post-test control group design. Teknik pengumpulan data yaitu melalui instrumen tes setelah proses pembelajaran yang didasarkan pada indikator. Untuk mengukur hasil belajar peserta didik menggunakan pre-test dan post -test. Pengolahan data memakai analisis deskriptif memperlihatkan bahwasannya rata-rata hasil belajar peserta didik kelas eksperimen lebih tinggi jika diperbandingkan kelas kontrol. Adapun hasil analisis inferensial memperlihatkan bahwasannya kedua data berdistribusi normal serta homogen sehingga dilanjutkan dengan uji analisis kovarian (anacova) dan diperoleh hasil ditolak serta  diterima. Sehingga hasil penelitian menunjukkan bahwa hasil belajar peserta didik lebih tinggi setelah dibelajarkan menggunakan multimedia interaktif dibandingkan dengan menggunakan power point.

Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar matematik asiswa pada materi himpunan melalui model pembelajaran open ended. Penelitian ini adalah jenis penelitian tindakan kelas yang dilaksanakan di SMP Negeri 1 Batudaa pada tahun ajaran 2022-2023. Penelitian dilaksanakan dengan melibatkan 26 siswa sebagai subjek penelitian. Istrumen yang digunakan berupa lembar pengamatan kegiatan guru, lembar pengamatan kegiatan siswa, dan tes hasil belajar siswa. Hasil pengamatan kegiatan guru menunjukkan kategori minimal baik atau sangat baik dengan presentase 97,06% sedangkan hasil pengamatan kegiatan siswa menunjukkan kategori minimal baik atau sangat baik dengan presentase 90%.Adapun tes hasil belajar menunjukkan bahwa banyaknya siswa yang mencapai nilai Kriteria Ketuntasan Minimal adalah 23siswa (88,46%) dan tidak tuntas sebanyak 3 orang siswa (11,54%). Jadi, rata-rata hasil belajar matematika siswa pada materi himpunan telah memenuhi indicator keberhasilan belajar.

Abstract

This study aims to determine the factors that most influence the rate of recovery of pulmonary tuberculosis patients using the Cox Proportional Hazard model. In the case of the cure rate of pulmonary tuberculosis patients, not all independent variables meet the proportional hazard assumption, so the stratified cox regression model is used. The stratified cox regression model used is the stratified cox model with interaction and without interaction involving pulmonary tuberculosis patients in one of the Gorontalo Hospitals. The results showed that the variables of shortness of breath, previous pulmonary tuberculosis patients, and smoking habits were the most significant factors affecting the recovery rate of pulmonary tuberculosis patients.
