Abstract

Abstrak. Jumlah kasus tetanus neonatorum di Sumatera menyebar mengikuti distribusiPoisson dan merupakan suatu data cacahan, sehingga jumlah kasus tetanus neonatorumdapat dimodelkan dengan pendekatan regresi Poisson. Dari analisis diperoleh faktorfaktoryang berpengaruh nyata terhadap jumlah kasus tetanus neonatorum di Sumateraadalah persentase ibu bersalin yang ditolong tenaga kesehatan dan persentase pendudukmiskin. Sebagian besar penduduk miskin diduga kurang peduli terhadap higienitas dalamproses kehamilan dan persalinan. Padahal proses kehamilan dan persalinan yang tidakhigienis sangat rentan untuk bayi baru lahir terinfeksi tetanus.

Abstract

The KIP scholarship is one of the scholarships available at IAIN Bukittinggi, and prospective recipients will be chosen based on the number of quotas available. Thus far, the selection process has been carried out by calculating the total value based on the sum of the percentages of each criterion arranged according to the level of importance. The procedure does not include a decision-making system for determining whether or not to accept the KIP scholarship. As a result, a decision support system is required to quickly and accurately determine which students are eligible for scholarships. In this research, the decision-making system compares the SAW and TOPSIS methods, with the latter using normalized weights in calculating the preference value as a determining value for alternative scholarship recipients to be selected. The SAW method was found to be more sensitive than the TOPSIS method in the data for the KIP scholarship 2020 recipients at IAIN Bukittinggi, with a sensitivity value of 96.87 compared to 81.96 for the TOPSIS method. Based on these findings, the SAW method can be recommended as a decision return system for KIP scholarship recipients to study at IAIN Bukittinggi the following year.

Abstract

Penelitian ini fokus untuk melihat pengaruh jumlah wisatawan domestik, jumlah penginapan dan objek wisata terhadap Pendapatan Asli Daerah (PAD) yang akan menunjang perekonomian tujuh kota di Sumatera Barat (Padang, Pariaman, Kota Solok, Padang Panjang, Sawahlunto, Payakumbuh, dan Bukittinggi). Pariwisata seharusnya mampu memberikan kontribusi positif bagi perekonomian Sumatera Barat yang dianugerahi keindahan alam berupa lautan, pegunungan, danau, dan lembah. Budaya Minangkabau yang khas dan turunannya seperti masakan, tarian, dan sebagainya menjadi nilai tambah daya tarik pariwisata Sumatera Barat. Pemerintah provinsi Sumatera Barat tentu harus mengetahui kekuatan dari daya tarik tersebut dengan mengkaji pengaruh jumlah objek wisata, penginapan, wisatawan, dan rumah makan terhadap peningkatan PAD.

Abstract

Studies on purchase intentions for halal products have focused more on the food and cosmetics sectors, while halal products in non-food sectors such as dishwashing soap have rarely been studied, even though the existence of these products is also important for Muslim consumers. This indicates a research gap that needs to be filled, especially considering the importance of hygiene in Islamic teachings and the increasing public awareness of the halalness of household products. Bukittinggi City was chosen as the study location because it is dominated by Muslim consumers who have a high concern for halal certification. The aim of this study is to assess the extent to which consumer attitudes and perceived usefulness can influence purchase intentions for halal-labeled dishwashing soap in Bukittinggi City. This study was conducted using a quantitative approach and a survey was conducted by distributing questionnaires to 124 respondents. The PLS (Partial Least Square) technique in the SEM (Structural Equation Modeling) approach was applied to analyze the data, with the help of SmartPLS.3.0 software. The findings in this study show that consumer attitudes and perceived usefulness significantly influence purchase intentions. The conclusion of this research is that the more positive consumers' attitudes and the greater usefulness they perceive from non-food halal products, the greater their purchase intention. The implication of this finding is the importance of businesses adopting Sharia values and providing halal education in their marketing strategies for household products.

Abstract

Siswa kelas VIII di SMP Negeri 4 Bukittinggi mempunyai kemampuan berpikir kritis matematika yang rendah, yang diakibatkan oleh metode pengajaran yang berfokus pada guru dan kurang beragam. Salah satu solusi untuk masalah ini ialah menerapkan model Numbered Head Together (NHT) dalam pembelajaran kooperatif. Tujuan utama penelitian ini ialah guna mengetahui sejauh mana siswa kelas VIII di SMP Negeri 4 Bukittinggi menerapkan model Numbered Head Together (NHT) dalam pembelajaran matematika. Penelitian ini ialah studi pra-eksperimental dengan desain perbandingan kelompok statis. Populasi penelitian ini meliputi sembilan kelas siswa kelas VIII SMP Negeri 4 Bukittinggi. Untuk penelitian ini, peneliti mengaplikasikan sampel yang tersusun dari dua kelas: VIII C selaku kelompok kontrol dan VIII B selaku kelompok eksperimen. Alat yang digunakan adalah alat evaluasi kemampuan siswa dalam berpikir kritis tentang matematika. Analisis statistik t-test digunakan untuk menganalisis data. Menurut analisis data ujian kemampuan berpikir kritis matematis siswa, diputuskan bahwa . Hal ini membuat peneliti menolak , karena . Perhitungan hasil menggunakan perangkat lunak Minitab juga mendukung hal ini, dengan nilai sebesar 0,3 < 0,05 = α. Sebab itu, bisa dirumuskan bahwa siswa kelas VIII di SMP Negeri 4 Bukittinggi memperoleh keuntungan penting pada model pembelajaran kooperatif Numbered Head Together (NHT) dalam menumbuhkan kemampuan berpikir kritis matematis siswa.

Abstract

Although low mathematics achievement and weak student self-efficacy remain persistent concerns in junior secondary education, evidence on the use of student-centered digital learning models in MTs mathematics classrooms remains limited. This study aimed to analyze the effectiveness of the Flipped Classroom learning model in improving mathematics learning outcomes and self-efficacy among eighth-grade students at MTsN 10 Agam. A quasi-experimental method with a posttest-only group design was employed. The population comprised all eighth-grade students across four classes, with class VIII.4 assigned as the experimental group and class VIII.1 as the control group through cluster random sampling. Data were collected using a mathematics achievement test and a self-efficacy questionnaire and analyzed using a t-test with SPSS. The findings showed that students in the experimental class achieved higher mathematics learning outcomes than those in the control class, with mean scores of 78.88 and 57.80, respectively, and a significant t-test result (tcount = 4.876 > ttable = 1.68). Students’ self-efficacy was also higher in the experimental class than in the control class, with mean scores of 99.04 and 92.70, respectively, supported by the hypothesis test result (tcount = 1.70 > ttable = 1.68). SPSS analysis further indicated a significance value of 0.000, confirming the effect of the Flipped Classroom model. These findings demonstrate that the Flipped Classroom learning model is effective in improving both mathematics learning outcomes and self-efficacy among MTs students. The study contributes to mathematics education by highlighting the pedagogical value of integrating technology and digital media to support independent learning, strengthen conceptual understanding, and enhance students’ confidence in their mathematical abilities.
