Abstract

Abstract A workshop to improve the competency of mathematics teacher, especially at the elementary school level, has held online on Saturday, September 05th 2020, 10.00 – 12.00 AM, by using zoom cloud meeting platform. The team of this workshop consists of three people, they are a head, a member, and a college student. The aim of this workshop is to improve the competency of mathematics teacher by using method of developing mathematic problems: type I and type II. The method used in this workshop are telling method, question and answer method, and simulation. The participants seemed enthusiastic in participating in this workshop. After the workshop ended, the team asks the participants to fill the evaluation questionnare. After that, the team asks each participants to do the simulation of the workshop by making mathematics olympiad problems by using the method of developing mathematics problems. It has been studied during the workshop. The outcomes of this workshop is publication of the recorded meeting of the workshop on YouTube channel, publication of the workshop article on the community service seminar, and the collection of mathematics olympiad problems made by participants. This workshop improves the ability of teachers to make mathematics olympiad problems on elementary school level. Abstrak Pengembangan kompetensi guru matematika melalui pelatihan pengembangan soal-soal olimpiade matematika tingkat sekolah dasar diselenggarakan dalam bentuk workshop dalam jaringan (webinar) pada hari Sabtu, tanggal 05 September 2020, pukul 10.00 – 12.00 WIB menggunakan platform zoom cloud meeting. Tim pelaksana terdiri dari tiga orang, yakni ketua, anggota, dan mahasiswa yang terlibat. Kegiatan ini bertujuan untuk meningkatkan kompetensi guru matematika dalam mengembangkan soal-soal olimpiade matematika dengan menggunakan metode pengembangan soal olimpiade, yakni tipe I dan tipe II. Metode yang digunakan dalam kegiatan ini adalah metode ceramah, tanya jawab, dan simulasi. Para peserta tampak antusias dalam mengikuti kegiatan workshop ini. Metode ceramah dan tanya jawab digunakan pada saat pelaksanaan workshop berlangsung. Setelah kegiatan workshop berakhir, peserta diminta untuk mengisi kuesioner evaluasi pelaksanaan workshop dan melakukan simulasi berupa praktik mandiri membuat soal olimpiade menggunakan metode pengembangan soal yang telah dipelajari selama workshop berlangsung. Hasil luaran workshop berupa unggahan video rekaman workshop di YouTube, publikasi artikel kegiatan pada seminar nasional, dan kumpulan soal olimpiade yang dibuat oleh peserta melalui metode pengembangan soal yang telah dipelajari. Dampak kegiatan ini adalah meningkatnya kemampuan guru dalam membuat soal olimpiade matematika tingkat sekolah dasar.

Abstract

Tuberculosis and COVID-19 are deadly infectious diseases with similar symptoms which mostly attacks lung. When these infections conduct in a single host simultaneously, it will give a low chance of survival. This thesis constructed and analyzed a compartmental tuberculosis and COVID-19 co-infection with anti-tuberculosis drugs intervention model. Our model claimed that the equilibrium point of the co-infection model is stable when the basic reproduction number or the number of the secondary infections is below 1. Numeric simulation was given, using parameter value calculated from the data of tuberculosis and COVID-19 situation in Indonesia period of March 2020 until March 2021 along with the result displayed in graphic. The basic reproduction number were obtained accordingly with the parameter value by 0.1819422898. This means, there are no Tuberculosis and COVID-19 co-infection transmission inside the population.

Abstract

The Vehicle Routing Problem (VRP) is an optimization problem in determining the route of packet distribution with limited vehicle capacity. Routing in the distribution of packets is important so that the shortest route will be sought so that the package arrives on time. One of the algorithms that discusses the search for vehicle routes with VRP problems is the Nearest Neighbor Algorithm, as for the stages in finding the best route by enumerating all possible sequences of existing routes and selecting the best set of routes in order to find the shortest route from one node to all other nodes. so it becomes a connected route.

Abstract

Salah satu permasalahan konsep dasar matematika yang ada di sekolah dasar adalah kesulitan dalam memahami konsep (miskonsepsi) materi operasi bilangan, khususnya bilangan pecahan. Oleh karena itu, diperlukan kegiatan kepada masyarakat dalam bentuk pelatihan kepada guru Sekolah Dasar (SD) untuk meningkatkan kompetensi guru sehingga dapat meminimalisir miskonsepsi yang dialami siswa. Pelaksanaan kegiatan dilakukan di wilayah Kota Bekasi dengan bekerja sama dengan mitra KKG Jatiasih Keota Bekasi. Berdasarkan hasil pengamatan guru, masih terdapat banyak miskonsepsi yang ditemui di sekolahnya terkait konsep materi bilangan pecahan dan operasinya.
