Abstract

PT. Sadar Jaya Manunggal merupakan salah satu perusahaan yang bergerak dalam pengadaan bahan bangunan. Perusahaan ini memiliki banyak cabang di kota-kota besar Indonesia, salah satunya di Kota Mataram yaitu di Jalan TGH. Faisal 78. Setiap hari, perusahaan akan melakukan pendistribusian bahan bangunan kepada para konsumen. Kegiatan pendistribusian ini memakan biaya dan waktu yang dipengaruhi oleh jarak setiap tempat yang menjadi tujuan pendistribusian, sehingga timbulah masalah bagaimana agar kegiatan pendistribusian ini  memakan biaya dan waktu seminimal mungkin, sehingga perusahaan memperoleh keuntungan yang optimal. Masalah tersebut merupakan bentuk Travelling Salesman Problem yaitu mencari rute terpendek untuk pendistribusian bahan bangunan kepada semua konsumen.  Pemecahan permasalahan tersebut adalah dengan merepresentasikan peta tujuan pendistribusian atau alamat para konsumen ke dalam bentuk graf lengkap berbobot, selanjutnya permasalahan diselesaikan menggunakan Algoritma Branch and Bound. Berdasarkan perhitungan menggunakan Algoritma Branch and Bound untuk optimasi rute pendistribusian bahan bangunan oleh PT. Sadar Jaya Manunggal Mataram menghasilkan solusi rute: (PT. Sadar Jaya Manunggal Mataram – UD. Mitra Utama – Pos Bangunan – Kunci Pelita – UD. Budi Rahman – Kurnia Jaya – UD. Salha – Ikhlas Bersama – PT. Sadar Jaya Manunggal Mataram) dengan total jarak 122,3 km.

Abstract

AbstractThe problems in this study are whether the application of image media and cart sort learning methods can improve student learning outcomes in PAI subjects at MIN 2 Padangsidimpuan. The purpose of this study is to improve student learning outcomes, especially in Fiqh material in carrying out fard prayer through a combination of picture media and cart sort method. While the usefulness of this study is to improve the quality of Islamic Education in Elementary School learning. The research method that I use is Classroom Action Research (CAR), which is action research conducted in the classroom to improve student learning outcomes. This research was conducted in two cycles. Each cycle consists of steps in planning, implementing, observing, and reflecting. This research was conducted at MIN 2 Padangsidimpuan. Based on the results of the research in the first cycle, the results of research on student activity at the first meeting were still lacking and increased in the next action. Then from the study results in the pre-study the percentage of completeness was only 53.33%, in the first cycle of the first meeting there had not been an increase in learning outcomes, but obtained a percentage of completeness of 33.33%, while the average score in the first meeting cycle was 59.87. Furthermore, at the second meeting the total percentage of completeness was 66.66%. This means that there has been an increase in learning outcomes from 33.33% from the first meeting. While the average value of the second meeting was 70.87. This means that for the average value of student learning outcomes increased by 11% from 59.87 to 70.87. Whereas in the second cycle the results of student activity research have also been increased from before because many students have been motivated in carrying out the learning process. In addition, the learning outcomes in the first cycle of the second meeting obtained 80% completeness with an increase in the first cycle of 13.34%. While the average value obtained in the second cycle of the first meeting was 73.53. Furthermore, at the second meeting achieved 100% learning outcomes with an increase of 20% from the first meeting. While an increase in the average value of student learning outcomes at the second meeting was 84.94. Keywords: Learning Outcomes, Image Media and Card Sort Method

Abstract

Zero-divisor graph is a geometric representation of a commutative ring. Zero-divisor graph of ring R that denoted by TR, defined by a graph whose vertices are all elements of zero-divisor set of a ring R, and two distinct vertices a and b are adjacent if and only if ab=0. In this paper, we will study some of the characterizations of the zero-divisor graph of integers modulo ring ( Zn). This study aims to know some forms of zero-divisor graph of ring (Zn ) and its properties. The method that used in this paper is deductive proof, by taking some example of zero-divisor graph of integer modulo ring ( Zn), then generalized the characterization of example. The firts result is if n=p^2, with p is a odd prime number, then the zero-divisor graph of ring is a complete graph. Then the second result is if n=p1p2, with p1 and p2 are different prime numbers, then the zero-divisor graph of ring is a complete bipartite graph and the diameter is 2.

Keberhasilan dan kemampuan bersaing suatu lembaga pendidikan terlihat pada mutu pendidikan itu sendiri. Dalam kebersaingan pendidikan berkaitan erat dengan manajemen strategi untuk menentukan langkah-langkah yang akan diambil kedepannya. Keputusan ini terletak dibawah kekuasaan pimpinan sekolah. Tanpa strategi yang tepat, mutu pendidikan tidak akan berhasil untuk menentukan mutu secara menyeluruh di semua komponen pendidikan. Penelitian ini bertujuan untuk menganalisis masalah strategik kepala sekolah dalam meningkatkan mutu pendidikan dan daya saing di SDN 02 Suak Tapeh. Dengan metode kualitatif deskriptif, pengumpulan data menggunakan observasi, wawancara partisipan, dan dokumen yang relevan. Adapun informan penelitian ini adalah kepala sekolah, dewan guru dan staff pendidikan. Teknik analisis data dengan menggunakan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini adanya relevansi atau keterkaitan antara manajemen strategi dalam meningkatkan mutu pendidikan dan daya saing sekolah. Mutu pendidikan tidak hanya mencakup pencapaian prestasi siswa, tetapi juga kualitas pengajar serta efektivitas program sekolah secara keseluruhan. Dalam konteks persaingan, mutu pendidikan menjadi tolok ukur utama yang menentukan sejauh mana sebuah sekolah mampu bertahan dan berkembang di tengah dinamika perubahan pendidikan. strategi dengan kualitas pendidikan dan kualitas daya saing. Kualitas pendidikan berarti semua yang merupakan standar tercapainya pendidikan berkualitas baik dari segi prestasi siswa, kualitas guru, serta program sekolah secara keseluruhan. kualitas pendidikan adalah salah satu tolak ukur terhadap kemampuan sekolah untuk bersaing.

Abstract

The aim of this research is to develop a Smart Box app for children aged 5-6 years. Type of development research (R&D) with the ADDIE research method (Analyze, Design, Development, Implementation, and Evaluate). The subjects used in this research were 12 children aged 5-6 years. The data collection method uses observation and the data analysis technique used is descriptive qualitative. The score results from this research and development were that in the first trial the APE Kotak Pintar got a score of 17 with a percentage of 53.2%, then in the second trial it got a score of 23 with a percentage of 71.8%, for the third trial it got a score of 28 with a percentage of 87. .5% and in the fourth or final trial, they got a score of 30 with a percentage of 93.7%. The results of the cognitive development of children aged 5-6 years had increased, which can be seen from the final results of the trial, the average child was in the Very Well Developed category. (BSB). Based on the results above, it can be concluded that the APE Smart Box can stimulate cognitive development in children aged 5-6 years.
