Dismenorea merupakan salah satu keluhan umum yang dialami oleh wanita saat menstruasi, ditandai dengan nyeri pada perut bagian bawah yang dapat mengganggu aktivitas sehari-hari. Penanganan dismenorea secara farmakologis memang umum dilakukan, namun konsumsi jangka panjang dapat menimbulkan efek samping. Oleh karena itu, dibutuhkan alternatif pengobatan yang aman dan alami, salah satunya adalah air kelapa hijau. Penelitian ini bertujuan untuk mengetahui pengaruh konsumsi air kelapa hijau terhadap penurunan dismenorea pada mahasiswi S1 Keperawatan Institut Citra Internasional. Jenis penelitian yang digunakan adalah eksperimen dengan desain pra-eksperimental. Populasi penelitian berjumlah 81 mahasiswi semester 8, dengan sampel sebanyak 30 orang yang dipilih menggunakan teknik purposive sampling berdasarkan kriteria tertentu. Penelitian dilaksanakan di rumah responden dan data dikumpulkan menggunakan kuesioner skala nyeri Numeric Rating Scale (NRS), yang kemudian dianalisis menggunakan uji Wilcoxon Match Pairs Test karena data berdistribusi tidak normal. Hasil penelitian menunjukkan adanya penurunan rata-rata nyeri menstruasi dari 3,23 sebelum intervensi menjadi 1,67 setelah konsumsi air kelapa hijau. Hasil uji statistik menunjukkan nilai p = 0,000 (< 0,05), yang berarti terdapat pengaruh yang signifikan antara konsumsi air kelapa hijau terhadap penurunan dismenorea. Dengan demikian, dapat disimpulkan bahwa air kelapa hijau efektif sebagai terapi nonfarmakologis dalam menurunkan nyeri menstruasi. Peneliti menyarankan agar masyarakat dapat memanfaatkan air kelapa hijau sebagai alternatif alami untuk mengurangi intensitas nyeri haid tanpa ketergantungan pada obat-obatan kimia.

Abortion is one of the leading causes of maternal mortality especially in developing countries where crude methods are frequently used. Studies on the level of knowledge, attitude and practice of unsafe abortion among in-school adolescents are sketchy. This study was conducted to fill these gaps in knowledge. Cross-sectional survey design was adopted while simple random sampling technique was used to select five secondary schools in Oyo West Local Government Area. Data were collected from 200 female participants using validated questionnaires and analyzed with descriptive and Chi-square (χ²) statistics to answer three research questions and test two hypotheses, respectively. The result revealed that 83% of in-school adolescents had good knowledge of abortion, 80% had a positive attitude toward abortion, while 65% indicated that they had carried out abortion. Furthermore, the result revealed that attitude significantly influenced the practice of unsafe abortion (χ² = 30.307, p < 0.05), while age did not (χ² = 4.830, p > 0.05). The study concluded that female in-school adolescents (13-19) age bracket had good knowledge and positive attitude toward abortion and had practiced abortion more than once. The study recommended effective counseling and targeted health campaigns on the danger of engaging in unsafe abortion among in-school adolescents.

Mathematics phobia and general learning difficulties continue to pose significant barriers to students’ achievement in Nigerian secondary schools. Given the importance of mathematics to both academic progression and future career opportunities, the persistence of these challenges is closely linked to the instructional approaches employed by teachers. This study examined the extent to which instructional strategies adopted by mathematics teachers influence students’ experiences of phobia and learning difficulties in senior secondary schools across Kwara State. The research adopted a descriptive survey design, with a sample comprising fifty purposively selected mathematics teachers and one hundred randomly chosen students from Ilorin East and West Local Government Areas. Data were gathered using a researcher-developed questionnaire that was validated and yielded a Cronbach's Alpha reliability coefficient of 0.75. Analysis of data through frequency counts and mean scores indicated that teachers made limited use of diverse instructional strategies (mean = 1.27, below the 1.50 benchmark). Results further showed that students exhibited high levels of mathematics-related phobia (weighted average = 2.28) and moderate-to-high levels of learning difficulties (weighted average = 2.21). The study recommends a pedagogical shift from conventional methods toward interactive strategies that integrate real-life contexts and technological applications, thereby making abstract ideas more concrete and reducing learner anxiety. The findings hold theoretical relevance for enriching discussions on instructional reform in mathematics education and practical significance for guiding teachers toward practices that encourage positive dispositions and enhance performance among students.
