Abstract

This research uses a website-based wordwall learning model, a technology-based learning model that utilizes touchscreen technology as the primary medium in the teaching and learning process. The objectives of this research are: 1) To explain the steps for developing a website-based multiplication wordwall for second-grade mathematics at SD Negeri Grogol 2 Depok, 2) To describe the validation of the website-based multiplication wordwall for second-grade mathematics at SD Negeri Grogol 2 Depok, and 3) To describe the effectiveness of the website-based multiplication wordwall for second-grade mathematics at SD Negeri Grogol 2 Depok. This research was conducted using the Research and Development (R&D) method, implemented over two cycles, one on a small scale and one on a large scale, using the Dick and Carey Model. The results of this study indicate that in cycle 1, student learning outcomes in multiplication increased by 85%, categorized as sufficient. The average score was only 85 out of all students' scores. Meanwhile, in cycle II, the implementation of the website-based wordwall media achieved a 90% improvement, categorized as very high. The average student learning achievement for cycle II was achieved. Based on these two cycles, it can be concluded that the implementation of the website-based wordwall media in Mathematics, particularly in the Multiplication subject, can improve student learning outcomes in Grade 2 of SDN Grogol 2 Depok.

Abstract

Aim: This study of plumbing system plan is  aimed at planning a plumbing system that is compatible with clean water, waste water and rain water management at Tunjungan Plaza apartment, Surabaya City, Indonesia according to SNI 8153-2015, and meet 5 aspects of safety, security, simplicity, beauty, and economy.  It applies water supply system which commonly used for tall buildings, namely Roof Tank system. Methodology and Result: Plumbing system planning methods are collecting and analyzing fluctuation in water use, planning clean water and recycled water systems by endorsing alternative piping for clean water and recycled water. In addition to water supply, recycled water system that utilizes waste water to be recycled for flushing closets and watering plants also required to be implemented. Average daily water consumption is 268 m3/day for clean water and 44 m3/day for recycled water with the capacity of ground water tank for clean water is 564.54 m3 and recycled water is 62 m3. Conclusion, significance and impact study: Clean water supply system will implement roof tank system and recycled water will reutilize wastewater for flushing on toilet tank and watering the plants. Waste water use separated system between grey water and black water and then distributed to STP to be treated and reused for flushing water closet and watering plants. Rain water goes to infiltration well by gravity through designed 1 well. Total amount of investment of plumbing equipment is Rp 2,157,697,501,- with cost of water supply per unit Rp 4,445,643,- meanwhile waste water piping cost per units is Rp 1,070,711,-.
