Abstract

Abstrak. Berdasarkan pengalaman saat melaksanakan PPL di SMPN 18 Mataram, aktivitas belajar siswa sangat rendah dan berdampak pada rendahya prestasi belajar matematika. Hal ini dikarenakan pembelajaran di kelas berpusat pada guru dan siswa hanya menerima informasi saja. Siswa aktif bermain namun pasif dalam kegiatan belajar. Guna mengatasi permasalahan tersebut, dicoba penerapan model pembelajaran kooperatif dengan pendekatan AIR (Auditory, Intellectualy, Repetition). Tujuan penelitian ini adalah meningkatkan aktivitas dan prestasi belajar siswa kelas VIIIA SMPN 18 Mataram yang berjumlah 26 orang. Jenis penelitian ini adalah penelitian tindakan kelas yang dilakukan dalam 3 siklus. Indikator keberhasilan penelitian ini adalah aktivitas belajar siswa dikatakan meningkat apabila terjadi peningkatan skor aktivitas dari skor sebelumnya dan minimal berkategori tinggi, prestasi belajar dikatakan meningkat apabila terjadi peningkatan nilai rata – rata siswa dari nilai rata – rata sebelumnya dan minimal mencapai nilai 55. Hasil penelitian menunjukan aktivitas dan prestasi belajar siswa mengalami peningkatan. Skor aktivitas siswa untuk setiap pertemuan dari siklus I, II dan III berturut – turut yaitu 3,5; 6,2; 9,9; 8,0; 11,4; 12,6 dan pada siklus III aktivitas siswa berkategori sangat tinggi. Nilai rata – rata siswa pada siklus I, II, dan III berturut – turut yaitu 41,10; 54,42; 58,42. Dari hasil yang diperoleh, dapat disimpulkan bahwa penerapan model pembelajaran kooperatif dengan pendekatan AIR (Auditory, Intellectualy, Repetition) pada materi pokok Fungsi dapat meningkatkan aktivitas dan prestasi belajar siswa kelas VIIIA SMPN 18 Mataram tahun ajaran 2010/2011. Kata kunci : model pembelajaran kooperatif, pendekatan AIR, aktivitas, prestasi.  Abstract. Mathematics learning achievement of SMPN 18 student is low caused a lack of student activities. These information obtained from observations at PPL activity in SMPN 18. Learning problem is learning centered teacher. Student was only received information from teacher. Auditory Intellectualy and repetition (AIR) opproach implemented to solve learning problem. This research pruposed to improve student achievement and learning activities of 26 students of 8th grater on SMPN 18. Teaching research was implemented in 3 cycles.

Abstract

Vendor managed consignment inventory (VMCI) adalah suatu strategi kolaborasi yang terjalin diantara pihak-pihak yang terkait dalam supply chain, dimana vendor sebagai supplier mempunyai wewenang untuk memutuskan order quantity yang harus dikirimkan ke buyernya serta menjadi pemilik barang tersebut sampai barang tersebut terjual atau dipakai. Integrasi pada sistem supply chain ini terjadi karena adanya information sharing dan business process reengineering. Pada penelitian ini akan dilakukan analisa keuntungan dari strategi vendor managed consignment inventory (VMCI) pada vendor tunggal multi retail jika permintaan konsumen bervariasi ditinjau dari minimasi total biaya yang dihasilkan. Pada penelitian ini dikembangkan algoritma untuk menyelesaikan model matematis yang telah dibuat. Selain itu, pada penelitian ini juga dilakukan analisa sensitivitas untuk mengetahui parameter yang meliputi biaya pesan vendor, biaya simpan vendor, biaya storage retail, biaya opportunity retail yang ditanggung vendor, biaya pesan retail, service level retail dan standar deviasi permintaan retail. Pada penelitian ini juga membandingkan model persediaan consignment dengan model Vendor Managed Consignment Inventory (VMCI). Percobaan numerik dari model ini menyatakan bahwa model VMCI lebih menguntungkan dibandingkan dengan model persediaan consignment.Kata Kunci: Vendor Managed Inventory, Consignment, Permintaan Probabilistik

Abstract

Raw materials are a significant requirement in the production process for manufacturing companies. In meeting the needs of raw materials for the production process, most manufacturing firms rely on suppliers. Supplier selection is an essential part of manufacturing companies. From several supplier selection criteria, quality is one of the fundamental standards and is used in supplier assessment. Selecting suppliers based on the quality of their products will have a positive impact on manufacturing companies, such as increased profits through reduced operational costs and increased market share. The problem faced is the lack of accuracy in choosing qualified suppliers. In this study will compare two suppliers at manufacturing companies and pick one that has a higher capability value. Supplier selection is made by using multiple characteristic capability indexes. The Supplier will be selected by comparing the ratio of two suppliers. Numerical calculations are performed on leather suppliers in shoe companies based on bursting quality, tear strength, tensile strength and elongation. The result of the calculation can be seen that supplier B is chosen as a better supplier. Characteristics of quality will affect the production process and application of shoes.

Abstract

Linear Programming is a course under the scope of algebra that must be mastered by mathematics education students. The low ability to solve linear programming problems can affect student performance when they become a teacher. This study aims to analyze the need for developing learning videos in Linear Programming courses for students of the Mathematics Education Study Program. The method used is development research which consists of Preliminary Analysis, Product Prototype, and Assessment. The research subjects were 30 students in the 7th semester of mathematics education and had attended online Linear Programming lectures in the previous semester. Data were collected by conducting written tests, questionnaires, and interviews and analyzed quantitatively descriptively. The results of the written test analysis showed that the students' ability to solve linear programming problems was low. Based on interviews, it is also known that students are not enough just to learn through modules and virtual meetings. Students tend to need learning videos/records to repeat explanations when studying the material independently. Therefore, there is a great need for learning videos that can optimize online learning of Linear Programming courses.

Abstract

The metric dimension is a concept that has many applications, such as robotic navigation. This concept will distinguish each vertex of a graph based on some vertices. The distinguishing vertices are called the basis of the graph. Let G be a connected graph, the metric dimension, dim(G), is the smallest cardinality of the basis of graph G. On this paper, we present the metric dimensions of the bridge graph of a homogeneous caterpillar graph Cm,n and a generalized flower pot graph $C_p-K_{(q_1, q_2,\cdos,q_p}$. This research was conducted by the approach of structure analysis by location of the bridge vertices, the edge of the bridge, and the order of the graph. The results show that the metric dimensions of the bridge graph are at least can be reduced at most 2, and the maximum values are the same as the value of $m(n-1)+ \sum_{i=1}^p q_i- 2p$.Keywords: Metric dimension, caterpillar, unicyclic, bridgeMSC2020: 05C12
