Abstract

Khalid Bin Walid Islamic Boarding School is one of the Islamic boarding schools in Rokan Hulu Regency. This school is located in a water crisis area with complex groundwater sources. This study aims to determine the potential of groundwater as a reference for drilling wells and to determine the structure of the subsurface layer by using the geoelectrical method. The geoelectrical method is a method that is widely used, and the results are promising, namely, to obtain an overview of the subsurface soil layers and the possibility of groundwater presence. The configuration used in this study is the Schlumberger configuration using the basic principle of current propagating in the earth when injected in all directions and the assumption that the potential of the subsurface rock layer is the same. Data will be collected on four tracks, with a track length of 100-200 m. From the data processing results, it was found that potential sources of groundwater on track 3 with a depth of 13.7–30.3 m with alluvium rocks were suspected. Groundwater on this track can be used as a source of clean water using drilling.

Abstract

The importance of test question planning as a critical element in improving the quality of education is undeniable as it helps teachers evaluate student understanding. The creation of questions must consider the level of difficulty, which is often divided into three categories: easy, medium, and difficult. Predicting the difficulty level of questions has great importance as it helps teachers create test questions that match students' abilities. In this study, we view the identification of item difficulty as a classification problem. The data used includes questions from elementary and junior high school, with various machine learning methods applied to perform classification. We tested Random Forest, Logistic Regression, SVM, Gaussian, and Dense NN, considering embedding, lexical, and syntactic features. The evaluation results show that the best method in identifying the difficulty level of questions in subjects is using Random Forest, resulting in an accuracy of 84%. Meanwhile, in other cases, the best method is also Random Forest, with an accuracy of 80%. Our research shows that the use of feature embedding and TF-IDF has a significant positive impact on the accuracy of the resulting model.

Abstract

The fabrication of transparent conducting electrodes (TCEs) is dominated by indium tin oxide (ITO). Some efforts are being made to find alternative materials as a substitute for ITO. Cu nanowire (CuNWs) is an equivalent candidate as a replacement for ITO but has a weakness that is easily oxidized. In this contribution, we report an increase in the performance of CuNWs, which can reduce the effect of oxidation. In this study, we provide a coating of CuNWs using PVP, PVA, and silver nanoparticles (AgNPs). The morphology, formation structure, and conductivity of CuNWs have been investigated by scanning electron microscope (SEM), X-ray diffraction (XRD), and IV meter. The average length and diameter of the CuNWs were 5.5 μm and 120 nm, respectively. The transparent conducting has a stable conductivity after coating with PVP, PVA and AgNPs. The application of transparent conducting electrodes are sensors, electronic devices, solar cells, and organic light-emitting diodes (OLEDs).

Abstract

Sungai Batang Lubuh merupakan salah satu sungai yang besar di kabupatan Rokan Hulu, Riau. Sungai ini melewati banyak kecamatan dan mempunyai nilai penting bagi penduduk yang tinggal disekitar. Penelitian mengambil lokasi yang berdekatan dengan galian pasir yang berada di Tanjung Berani, Kec. Bangun Purba Timur. Mengingat daerah aliran sungai batang lubuh yang berada disana digunakan sebagai tempat rekreasi dan terdapat galian pasir. Pada penelitian ini dilakukan pengukuran beberapa parameter untuk mengukur kualitas air seperti suhu, kecerahan, kekeruhan, pH, TSS, DO dan BOD5 serta Pengukuran kandungan logam berat menggunakan metoda Atomic Absorption Spectroscopy (AAS). Secara umum kualitas perairan di Sungai Batang Lubuh masih layak dan mendukung untuk kehidupan organisme. Rata-rata kandungan logam pada air sungai antar stasiun bervariasi, untuk logam Zn dan Cr lebih tinggi yaitu (1,9785 ± 1,2231 mg/L) dan (0,6893 ± 0,0359 mg/L ) dari pada logam Cu dan Hg (0,1952 ± 0,1280 mg/L) dan (0,1265 ± 0,0086 mg/L)

Abstract

This study examines the influence of the Learning Cycle 7E instructional model on the cognitive learning outcomes of Physics students in Class X of SMAN 3 Rambah Hilir. This research is a pre-experimental study with a quantitative descriptive approach using a One-Group Pretest-Posttest design. The study was conducted in Class X-2 of SMAN 3 Rambah Hilir, focusing on temperature and heat during April in the even semester of the academic year 2014/2015. The sample consisted of 22 students from Class X-2 of SMAN 3 Rambah Hilir, selected through purposive sampling. The research instrument was a Physics learning outcomes test. Based on the data obtained from the pretest and posttest, where the students' pretest average score was 40.3, and the posttest average score was 82.4, the magnitude of the influence on students' cognitive learning outcomes in Physics was assessed using the N-gain test, which fell within the high criteria with an average N-gain value of 0.70. The impact of the Learning Cycle 7E instructional model was observed through the achievement of learning objectives. Before the treatment, only 2 out of 15 learning objectives were achieved by students, with a classical mastery level of 13.3%. However, after applying the Learning Cycle 7E instructional model, 13 out of 15 learning objectives were achieved, with a classical mastery level of 86.7%. This result indicates a significant influence of the Learning Cycle 7E instructional model. Based on the research findings, there is an influence on students' cognitive learning outcomes in Physics when using the Learning Cycle 7E instructional model.
