Abstract

Developing entrepreneurial characters and skill is one of the goals of Faculty of Teacher Training and Education Pancasakti University Tegal. To achieve this goal, the learning process needs to support the development of entrepreneurial characters, such as self-confidence, hard work and unyielding, cooperative, independent, and active and creative. Learning activities should be able to provide opportunities for students to participate actively. Therefore, this study aimed at designing a Maple-integrated workbook to help students establish their entrepreneurial character. The workbook helps students build the character of independent in learning calculus, active and cooperative in solving problems, and creative in using Maple to explore the concept of calculus. This study employed Research and Development by adapting Borg and Gall's steps, which are preliminary information, design, preliminary development, validation and preliminary revision, field test and final revision. The entrepreneurial characters instrument is a questionnaire comprising statements that reflect the characters of entrepreneurship, which are self-confident, hard work, cooperative, independent, and active and creative. The result of questionnaire analysis showed that in general students’ entrepreneurial characters are in a good category, with the average score of entrepreneurial character is 2.85 out of 4.

Abstract

A factor that contributes to students’ low performance in Calculus is that some teachers and lecturers tend to explain the concept of integral by using a set of symbols, notations, and rules without providing any contexts or representations of the concept. This study was aimed at supporting college students’ understanding of integral by integrating Maple in the learning process using Maple-integrated workbook. This study adapted Brog and Galls’ procedures which consist of collecting preliminary information, planning, developing, validation and preliminary revision, field test, and final revision. The subject of this study was college students’ of Mathematics Education Department of UPS Tegal. The result showed that module developed was in a good criteria, and the conceptual understanding test showed that 82,4% students in the experimental class got a score of 71 or higher. Moreover, the average score of the experiment and control class also confirmed that the average of students’ score in experiment class was significantly higher than that of students in control class.

Abstract

ABSTRACT. In this paper, we study the problem of stationary infiltration on several types of homogeneous soil from a single trapezoidal channel. A governing equation in this problem is in the form of a nonlinear differential equation and is called the Richards’ equation. The equation can be solved more easily by transforming it into a modified Helmholtz equation. In this study, the Dual Reciprocity Boundary Element Method (DRBEM) was used to solve the modified Helmholtz equation numerically. Then, using the obtained solution, the numerical values of the Matric Flux Potential (MFP) for each soil type were computed and then compared. For the position of the same points, the Pima Clay Loam soil type has the highest MFP value, followed by Clay Loam and Sandy Loam.Keywords: Richards’ equation, modified Helmholtz equation, matric flux potential, DRBEM, single irrigation channel. ABSTRAK. Dalam artikel ini dibahas masalah infiltrasi stasioner pada beberapa jenis tanah homogen dari saluran irigasi tunggal bentuk trapesium.

Abstract

Kelurahan Tegalsari di Kota Tegal mempunyai permasalahan serius terkait pengelolaan sampah, terutama di RW X yang berdekatan dengan Pelabuhan Perikanan Pantai. Masalah ini disebabkan oleh aktivitas perikanan yang menghasilkan banyak limbah dan kurangnya kesadaran masyarakat akan pentingnya kebersihan lingkungan. Untuk mengatasi masalah tersebut, diadakan pelatihan pembuatan eco enzyme bagi ibu-ibu PKK di RW X. Tujuannya adalah memberikan solusi pengelolaan sampah organik secara mandiri dan ramah lingkungan. Pelatihan ini terbukti efektif meningkatkan pemahaman masyarakat tentang pembuatan dan manfaat eco enzyme. Metode pelaksanaan kegiatan ini adalah koordinasi, pemberian materi dengan metode ceramah, demonstrasi membuat eco enzyme, diskusi dan tanya jawab, sosialisasi manfaat dan penggunaan eco enzyme serta evaluasi. Hasil kegiatan ini yang telah diikuti 22 peserta adalah berjalan dengan baik, antusias dan aktif. Terdapat peningkatan pemahaman terkait pembuatan eco enzyme. Kegiatan pelatihan pembuatan eco enzyme ini merupakan langkah yang positif dalam pemberdayaan masyarakat. Dengan beberapa perbaikan, kegiatan serupa dapat menjadi lebih efektif dan berdampak lebih luas. Selain itu, penting untuk terus melakukan monitoring dan evaluasi terhadap keberlanjutan penggunaan eco enzyme oleh peserta pelatihan. Kata kunci : eco enzyme, pelatihan, PKK, limbah rumah tangga

Abstract

In this paper, steady infiltration problems into a homogeneous soil from a single triangular and trapezoidal irrigation channel are considered. The governing equation is Richard's equation that represents the movement of water in unsaturated soil. It is a non-linear equation and can be solved by linearizing to become a modified Helmholtz equation. Dual Reciprocity Boundary Element Methods (DRBEM) are used in this study to numerically solve the modified Helmholtz equation. Therefore, by using a provided solution, the numerical Matric Flux Potential (MFP) is calculated. This method was applied to the homogeneous soil problem of stationer infiltration from triangular and trapezoidal single irrigation. Both numerical solutions were compared. The result show that the MFP value from the triangular irrigation is higher than the trapezoidal irrigation. This indicates that content water from the triangular irrigation channel is higher than the trapezoidal irrigation channel.
