KAJIAN METODE ANALYTICAL HIERARCHY PROCESS (AHP) PADA PENGUKURAN KINERJA LINGKUNGAN PERUMAHAN VILLA ZEQITA MEDAN TUNTUNGAN DI MASA PANDEMI COVID-19

2024-05-17T09:20:49+07:00

ABSTRACT

This research calculates the selection of priorities that influence the measurement of environmental performance, namely using the Analytical Hierarchy Process (AHP) method, which is one of the decision making methods. To determine the priority level of choice, several dimensions can be used as a reference in measuring environmental performance. And in this research, 5 dimensions were obtained as a reference in determining priority levels in measuring environmental performance at the Villa Zeqita Medan Tuntungan housing complex during the Covid-19 pandemic, namely Accessibility, Drainage, Commercial Facilities, Waste Management and Green Open Space. The study carried out in this research was based on the results of a survey on the level of satisfaction of housing communities during the pandemic, which was then determined by ranking and arranging priorities using the AHP method. The results of the AHP analysis in this study concluded that the Accessibility criterion was the highest priority criterion for measuring residential environmental performance, with a weight of 0.359 or 35.9%. Then there are the Commercial Facilities criteria with a weight value of 0.251 or 25.1%, the Drainage criteria with a weight value of 0.203 or 20.3%, the Waste Management criteria with a weight value of 0.101 or 10.1% and finally the Green Open Space criteria which also have a weight value, namely 0.087 or 8.7%.

Etnomatematika: Eksplorasi Motif Ulos Batak Toba Dalam Pembelajaran Bangun Datar

2024-05-17T09:20:49+07:00

This research aims to explore examples of mathematical ideas found in the motifs of Batak Toba ulos fabric used in wedding ceremonies. Despite being derived from dialogues and observations, it was found that geometric principles such as symmetry, transformation, reflection, and repetition are manifested in the creation of Batak Toba ulos fabric for wedding ceremonies. Additionally, mathematical concepts such as straight lines, curves, circles, and polygonal shapes like triangles, squares, stars, hexagons, octagons, pyramids, and parallelograms are also present in the motifs of Batak Toba ulos fabric. This knowledge is crucial to be learned and taught to students as a source in contextual learning. Furthermore, it provides new insights to students about the diverse facets of mathematical knowledge, not just as a formal subject in school. Thus, mathematics learning can commence from real-life situations experienced by students.

EKSPLORASI GOWE NILARE TERHADAP KONSEP GEOMETRI

2024-05-17T09:20:50+07:00

Matematika merupakan bagian penting dalam kehidupan manusia, sedangkan budaya adalah gaya hidup yang berkembang dalam suatu kelompok atau masyarakat. Di Nias Selatan yang kaya akan budaya dapat menjadi sumber referensi bagi guru matematika untuk menciptakan media pembelajaran. Kebudayaan yang sangat menarik untuk dijadikan sebagai media pembelajaran matematika yaitu budaya “gowe nilare”. Pendekatan Penelitian yang digunakan dalam penelitian ini merupakan penelitian kualitatif dengan jenis penelitian deskriptif. Lokasi penelitian ini adalah di desa Hilisao’oto Kecamatan Sidua’ori Kabupaten Nias Selatan. Karena bentuk gowe nilare di Desa Hilisao’oto yang merupakan objek wisata yang dikunjungi oleh banyak orang. Instrumen yang digunakan adalah Lembar observasi, wawancara dan dokumentasi. Berdasarkan hasil penelitian dan pembahasan dapat disimpulkan bahwa didalam gowe nilare terdapat bentuk konsep matematika jika dilihat dari bentuknya terdapat konsep lingkaran, kerucut terpancung, dan tabung dapat sehingga gowe nilare ini dapat dijadikan sebagai media pembelajaran matematika khususnya pada materi lingkaran, kerucut terpancung, dan tabung. Sehingga peneliti menyarankan agar gowe nilare ini dapat dijadikan sebagai media pembelajaran khususnya pada materi lingkaran, kerucut terpancung, dan tabung dan budaya Nias lainya yang dapat dikaji dari sudut pandang tertentu sehingga dapat dijadikan sebagai media pembelajaran.

Philosophy and mathematics are very closely related and cannot be separated. Philosophy can open up views on how philosophy has shaped the understanding and application of number concepts. The contribution of ancient and modern philosophers in shaping our thinking about numbers, as well as expanding our view of numbers beyond just the concept of numbers. From Pythagoras's view of numbers as the basis of the structure of the universe to Bertrand Russell's contributions to mathematical logic, this article highlights how philosophy has helped expand our understanding of numbers. Discusses an in-depth understanding of various types of numbers, such as natural numbers, integers, and irrational numbers, as well as the mathematical properties that underlie number operations. The research method used is the library method by collecting data from various sources to provide rich insight into the relationship between philosophy and mathematics in the context of the concept of number. The results confirm the importance of the contribution of philosophy in defining, enriching, and developing the concept of number in mathematics

EKSPLORASI ALAT MUSIC OGUNG BATAK TOBA TERHADAP KONSEP GEOMETRI LINGKARAN

2024-05-17T09:20:50+07:00

This article delves into the profound meanings and symbolism of the traditional musical instrument Ogung in Batak Toba culture, particularly in the context of the concept of circular geometry. Ogung, a round and flat gong, serves not only as a musical instrument but also reflects greatness, balance, and the cycle of life in Batak Toba tradition. The concept of circular geometry is manifested in the physical form of Ogung, creating a profound connection between artistic form, philosophical values, and traditional art performances. This exploration invites readers to understand how the circle on Ogung not only resonates with harmonic melodies but also conveys a deep message about the unity of humans with nature and the local wisdom embedded in traditional art.

Keywords: Exploration,traditional musical instrument , concept of circular geometry

Optimisasi Robust pada Masalah Pickup dan Delivery dengan Ketakpastian Time Window

2024-05-17T09:20:50+07:00

The pickup and delivery problem with time window (PDPTW) is a problem related to planning the optimal route for a vehicle in providing transportation services to a number of customers with the aim of minimizing operational costs. The classic PDPTW model generally assumes that parameter values are certain. However, in practice it is difficult to find the exact value of a parameter. Time window uncertainty is often found in the pickup and delivery problem by transportation service providers. This is important for transportation service providers, because taking into account the uncertainty of the time window is expected to result in better travel routes. In this paper, a deterministic model of PDPTW was developed. Robust Optimization is used to solve the time window uncertainty. The time window uncertainty is assumed to be in a box uncertainty set. Furthermore, Robust counterpart model is developed which is computationally tractable using Linear Programming.
