Abstract

Daerah Irigasi (DI) Petapahan merupakan Daerah Irigasi yang terletak di Kabupaten Kampar dengan luas areal potensial 750,6 Ha. Irigasi Petapahan direncanakan untuk mengairi areal pertanian di tiga desa yang berada di Kabupaten Kampar yaitu Desa Pulau Tinggi, Desa Kampar, dan Desa Rambai. Namun Daerah Irigasi Petapahan pada kondisi eksisting hanya dimanfaatkan 451,5 Ha dan ditemuinya kekurangan air pada musim kemarau. Oleh karena itu perlu dilakukan evaluasi keseimbangan air dan usaha pengoptimalan di Daerah Irigasi Petapahan. Dalam penelitian ini dilakukan analisis ketersediaan air irigasi, analisis kebutuhan air irigasi, analisis keseimbangan air, dan pengoptimalan DI Petapahan. Analisis keseimbangan air dilakukan tiap periode setengah bulanan antara ketersediaan dan kebutuhan air. Hasil Evaluasi keseimbangan air menunjukkan bahwa ketersediaan air tidak mencukupi kebutuhan kebutuhan air berdasarkan pola tanam eksisting. Kondisi dimana terjadi surplus air pada bulan Januari, April, September hingga Desember sedangkan terjadi defisit pada beberapa bulan yaitu Februari, Mei Juni dan Juli menandakan bahwa belum optimalnya pengelolaan Daerah Irigasi Petapahan Namun setelah dilakukan optimalisasi pola tanam, maka ketersediaan air di Daerah Irigasi Petapahan masih mencukupi kebutuhan air irigasi dengan luas areal terlayani 750,6 Ha. Pola tanamnya adalah padi-padi/padi-palawija dengan sistem pemberian air secara 3 golongan ditambah suplesi bendung Tibun.

Abstract

Bencana akibat keruntuhan struktur jembatan yang tidak bisa diprediksi sebelumnya membutuhkan biaya rehabilitasi yang sangat besar. Hal ini diakibatkan oleh penurunan kemampuan atau kerusakan tidak dapat diidentifikasi lebih awal (peringatan dini). Sulitnya untuk memprediksi langsung kondisi struktur jembatan disebabkan oleh eterbatasan alat uji dan kondisi lingkungan pengujian. Pemantauan Kesehatan Struktural Structural Health Monitoring) merupakan usaha mengidentifikasi kerusakan meliputi penentuan kejadian, lokasi dan tingkat keparahan dari setiap kerusakan. Hal ini sangat penting dikaji karena struktur jembatan perlu dimonitor sebelum kegagalan bencana terjadi. Tujuan dari penelitian ini adalah mengevaluasi kondisi struktur jembatan akibat beban dinamis jembatan sehingga dapat digunakan untuk perencanaan pemeliharaan struktur yang rasional dan ekonomis. Kajian berpusat pada berbagai beban dinamis dari analisis jembatan Pelengkung Baja. Pendekatan deteksi kerusakan dilakukan berdasarkan Jaringan Saraf Tiruan (JST) dengan bantuan program komputer MATLAB. JST ini merupakan cabang ilmu kecerdasan buatan (Artificial Inteligence) yang berkerja berdasarkan sistem kerja otak manusia. Dalam penelitian ini, metode JST memerlukan statistic respons dinamis struktural sebagai indeks kerusakan untuk Pemantauan Kesehatan Struktur (SHM) sehingga dapat memprediksi kondisi kesehatan struktur jembatan secara cepat. Selanjutnya dilakukan verifikasi dengan menggunakan progam metode elemen hingga (SAP 2000). Analisis dilakukan untuk memperkirakan penilaian kondisi struktur jembatan meliputi lokasi kerusakan dan tingkat kerusakan yang mengacu pada pedoman penentuan nilai kapasitas jembatan. Diharapkan penelitian ini juga dapat menjadi masukan bagi pemerintah dan pihak yang terkait dengan inspeksi jembatan dalam memberikan penilaian yang tepat untuk pemeliharaan, perbaikan dan peningkatan fungsi jembatan.

Abstract

Reading is a receptive language skill. This study aimed to desctibe the reading comprehension skill experienced by third-grade students at SDN 3 Ketapang Raya. This study employed descriptive qualitative method and applied observation, documentation, interviews, and tests to collect the data. This study elaborated on data collection techniques from Milles and Hubberman to analyze the data. It included data collection, reduction data, data presentation, conclusions, and verification. The results indicated that several types of reading comprehension skills experience by students were: not understanding the text, low reading ability, difficulty in concentrating, careless toward punctuation marks, not being able to re-explain the text, and the last distress was recalling the text. Off all the reading skill types above, the most prominent experience was a lack of understanding of punctuation marks and difficulty to re-create the texts. The difference between this study and previous studies was that the previous one only wanted to know the students’ reading comprehension skills using story texts. In contrast, this study observed the students’ reading comprehension skills and investigated the types of students’ reading comprehension skills.

Abstract

Toddler health is an important indicator of public health and nation development. Midwifery care plays an important role in maintaining the health of toddlers, including observing the health of toddlers aged 24 months. This study aims to analyze the effectiveness of midwifery care in observing the health of 24-month-old toddlers in Kute Rayang Village, Central Aceh, Indonesia. This study used a cross-sectional observational design with a sample of 100 toddlers aged 24 months who were selected at simple random. Data was collected through interviews, observation, and physical examination. Data analysis was carried out using Chi-square and T-test. The results showed that midwifery care in observing the health of 24-month-old toddlers in Kute Rayang Village, Central Aceh, Indonesia was quite effective. As many as 80% of toddlers have undergone complete health observation by midwives. Observation of toddler health has increased complete immunization coverage (p<0.05), nutritional status of toddlers (p<0.05), and maternal knowledge about toddler health (p<0.05). Midwifery care in health observations for 24-month-old toddlers in Kute Rayang Village, Central Aceh, Indonesia is quite effective, but can still be improved. Increasing the effectiveness of midwifery care can be done through various efforts, including increasing the knowledge and skills of midwives, increasing community access to health services, and increasing community participation in maintaining the health of toddlers.

Abstract

Intimate partner violence (IPV) is a significant public health issue with devastating consequences for maternal and child health. This study investigates the prevalence and impact of IPV on pregnant women and their children in Bener Meriah Regency, Aceh, Indonesia, a region with limited research on this topic. A longitudinal study was conducted with 250 pregnant women recruited from antenatal clinics in Bener Meriah Regency. Data were collected through questionnaires and interviews at three time points: during pregnancy, six months postpartum, and one year postpartum. The questionnaires assessed IPV experiences, maternal mental health (depression, anxiety, and stress), and child health outcomes (birth weight, growth, and development). The prevalence of IPV during pregnancy was 32%. Women who experienced IPV were significantly more likely to suffer from depression, anxiety, and stress during pregnancy and postpartum. IPV was also associated with lower birth weight and an increased risk of developmental delays in children. In conclusion, this study highlights the serious consequences of IPV for maternal and child health in Bener Meriah Regency. The findings underscore the urgent need for IPV screening and intervention programs in antenatal and postnatal care settings. Midwives play a critical role in identifying and supporting women experiencing IPV.

Abstract

Early initiation of breastfeeding (EIBF) is critical for reducing infant mortality and improving child health outcomes. Midwives play a crucial role in promoting and supporting EIBF. This study investigated EIBF practices in Bener Meriah Regency, Aceh, Indonesia, focusing on the factors associated with midwives' knowledge, attitudes, and practices regarding EIBF. A cross-sectional study was conducted among 150 midwives in Bener Meriah Regency. Data were collected using a structured questionnaire that included items on sociodemographic characteristics, knowledge, attitudes, and practices related to EIBF. Descriptive statistics, chi-square tests, and logistic regression were used to analyze the data. The majority of midwives (87.3%) had good knowledge about EIBF. However, only 62.7% of midwives reported always assisting mothers with EIBF within one hour of birth. Factors significantly associated with midwives' EIBF practices included their age, years of experience, and place of work (urban vs. rural). While midwives in Bener Meriah Regency generally possess adequate knowledge about EIBF, there is a need to improve their practices in assisting mothers with EIBF, especially in rural areas. Targeted interventions, such as training programs and supportive supervision, are necessary to enhance midwives' skills and confidence in promoting and supporting EIBF.
