Abstract

The development of E-LKPD in Grade VII Mathematics Subject of SMPN 5 Linggo Sari Baganti is motivated by a teacher-oriented learning pattern, as well as limitations in the use of digital teaching materials such as E-LKPD. This research aims to produce valid and practical E-LKPD products so that they can be used in the learning process. The type of research used is Research and Development (R&D). The development model used in this study is a 4D model. The 4D model consists of 4 stages, namely define, design, develop and disseminate. The results of the development of E-LKPD were obtained through validity and practicality tests. The product validity test was validated by three validators consisting of one material validator, namely a teacher of Mathematics Class VII SMPN 5 Sari Baganti and two media validators, namely lecturers from the Department of Curriculum and Educational Technology, Padang State University. The product practicality test was carried out by conducting an E-LKPD trial for grade VIIB students of SMPN 5 Linggo Sari Baganti. The results of the validity test by a material expert and two media experts obtained an average score of 4.86, 4.86, and 4.8 respectively which was categorized as "very valid". The results of the practicality test obtained an average score of 4.6 with the category "very practical". Thus, it can be concluded that the E-LKPD developed is suitable for use as a teaching material in Mathematics Class VII Junior High School.

Abstract

Penelitian ini bertujuan untuk mengembangkan model prediksi nilai California Bearing Ratio (CBR) pada tanah lanau yang distabilisasi dengan abu ampas tebu menggunakan pendekatan Machine Learning Polynomial Regression. Ruang lingkup penelitian meliputi uji laboratorium dan pemodelan prediktif untuk menentukan kadar optimum abu ampas tebu yang memberikan peningkatan nilai CBR maksimum. Data diperoleh dari hasil uji laboratorium dengan 5 variasi campuran abu ampas tebu (0%, 2%, 4%, 6%, dan 8%) dan masing-masing 3 kali replikasi, sehingga total terdapat 15 data pengamatan yang digunakan sebagai dataset pelatihan model. Pemodelan dilakukan menggunakan algoritma Polynomial Regression orde dua dengan pustaka scikit-learn pada Python. Hasil pengujian menunjukkan bahwa nilai CBR tanah asli sebesar 2,94% meningkat menjadi 7,39% pada campuran 6% abu ampas tebu, atau terjadi peningkatan sebesar 151% dibandingkan tanah asli. Persamaan regresi yang diperoleh adalah: CBR=−0.15x2 +1.9x+2.8  Model menghasilkan nilai koefisien determinasi (R²) sebesar 0,94 dan Root Mean Square Error (RMSE) sebesar 0,28, menunjukkan tingkat akurasi tinggi dalam memprediksi hubungan non-linear antara kadar abu dan nilai CBR. Model ini dapat digunakan sebagai alat bantu analisis berbasis data untuk optimasi campuran tanah stabilisasi ramah lingkungan

Abstract

Pembangunan suatu gedung atau infrastruktur pada suatu daerah atau kawasan sebaiknya perlu memperhatikan infrastruktur pendukung seperti saluran drainase agar tidak mengganggu aktivitas dan kenyamanan pengguna dan menyebabkan kerusakan pada gedung atau infrastruktur itu sendiri. Pada Pembangunan stadion yang akan dibangun di Tanjung Haro Kecamatan Sikabu-Kabu Kabupaten Lima Puluh Kota, maka perencanaan drainase harus dirancang dengan baik. Untuk itu tim pengabdian Sekolah Tinggi Teknologi Payakumbuh yang terdiri dari tim dosen dan mahasiswa melakukan pengabdian dengan agenda kegiatan ”Pengukuran Perencanaan drainase Pada Pembangunan Stadion di Tanjung Haro Sikabu-Kabu Padang Panjang Kabupaten Lima Puluh Kota”. metode yang digunakan adalah metode pengukuran polygon untuk mendapatkan rancangan saluran drainase yang akan dibuat. Kegiatan pengukuran ini menggunakan alat ukur theodolite dan waterpass yang dilakukan oleh mahasiswa teknik sipil dipandu oleh tim dosen STT Payakumbuh. Selanjutnya hasil pengukuran yang diperoleh diolah untuk mendapatkan gambar rancangan saluran drainase stadion. Sehingga dapat memudahkan masyarakat Tanjung Haro untuk merealisasikan pembangunan stadion yang direncanakan beserta saluran drainasenya.

Abstract

The community service activity represents the implementation of the Tri Dharma of Higher Education, especially in knowledge applications in the field of civil engineering focusing in water resources for community empowerment. The activity entitled Calculation of Irrigation Water Requirements for the Batang Sikali Irrigation Area, Payakumbuh City aims to (1) analyze irrigation water requirements in the Batang Sikali Irrigation Area and (2) to enhance the knowledge of the Water User Farmers Association (P3A) regarding irrigation water requirements to support agricultural production increasing. The activity was conducted in the Batang Sikali Irrigation Area, Payakumbuh City. The methods included the collection of precipitation data, climatological data, cropping patterns, and existing irrigation conditions, followed by the calculation of irrigation water requirements. The results show that the highest irrigation water requirement occurred in the second period of April, amounting to 196.334 m³/ha or 2.272 L/s/ha, while the lowest irrigation water requirement occurred in the first period of April, amounting to 35.511 m³/ha or 0.411 L/s/ha. Through this activity, hopefully the water user association members gained a better understanding of irrigation water requirement calculations and efficient irrigation water management, which is expected to support sustainable irrigation management and improve agricultural productivity.
