Abstract

Munculnya persaingan dalam dunia bisnis/usaha merupakan tantangan yang harus dihadapi oleh setiap perusahaan. Perusahaan dimanapun pasti akan menghadapi ketatnya persaingan global, perkembangan yang terjadi pada dunia teknologi dan digital yang sangat cepat dan perubahan-perubahan yang tidak bisa dikontrol, sehingga diharuskan setiap perusahaan harus menyesuaikan diri dengan perkembangan dan perubahan yang ada. Setiap bidang usaha mempunyai tujuan untuk memperoleh keuntungan dan hal ini tidak serta merta mudah dicapai. Setiap pengusaha dalam menjalankan usahanya harus membaca situasi pasar dan mencegah serta menangani faktor-faktor yang membuat kerugian dalam usahanya. Penerapan quality control atau pengendalian mutu menjadi hal yang harus di gunakan oleh para pengusaha agar produk yang mereka produksi dan jual tetap eksis di kalangan masyarakat. Untuk mencapai keinginan dan tujuan, maka para pengusaha harus melakukan berbagai upaya untuk memuaskan para konsumen sehingga konsumen tetap loyal kepada perusahaan dan produk yang memiliki kualitas yang baik. Apabila proses produksi bagus dan terjamin kualitasnya, maka konsumen akan merasa puas dengan produk yang diciptakan. Kualitas produk menjadi hal yang harus sangat diperhatikan oleh para pengusaha dalam memproduksi barangnya sehingga perusahaan dapat dan mampu bersaing dengan perusahaan lainnya. Kata kunci: quality control, kualitas produk.

Perusahaan dimanapun pasti akan menghadapi ketatnya persaingan, perkembangan yang terjadi pada dunia teknologi dan digital yang sangat cepat dan perubahan-perubahan yang tidak bisa dikontrol, sehingga diharuskan setiap perusahaan harus menyesuaikan diri dengan perkembangan dan perubahan yang ada. Setiap bidang usaha mempunyai tujuan untuk memperoleh keuntungan dan hal ini tidak serta merta mudah dicapai. Menghadapi dinamika dunia usaha yang penuh dengan persaingan, berbagai upaya yang dapat dilakukan untuk menjaga kelangsungan operasional suatu perusahaan, salah satu upaya yang dapat dilakukan perusahaan adalah dengan melaksanakan proses produksi yang terus berkesinambungan dan berkembang sehingga kelangsungan hidup perusahaan terjamin. Kelangsungan proses produksi dalam suatu perusahaan dipengaruhi berbagai faktor antara lain persediaan bahan baku yang menjadi unsur utama dalam kelancaran proses produksi. Untuk itu, setiap perusahaan harus memiliki perencanaan kebutuhan bahan baku. Dalam pengadaan persediaan bahan baku seringkali terjadi masalah yang tidak terduga, salah satunya adalah kekurangan bahan baku yang mengakibatkan proses produksi tidak dapat berjalan dengan lancar sehingga diperlukan suatu pengendalian persediaan agar tidak terjadi kekurangan bahan baku. Tujuan dari pengendalian adalah untuk meminimalisir biaya-biaya operasional seminimal mungkin sehingga akan mengoptimalisasikan kinerja perusahaan. Biaya operasional merupakan sejumlah biaya yang dikeluarkan perusahaan untuk menjalankan aktivitas bisnis. Kata Kunci : metode kuantitas produksi ekonomis, biaya operasional

Abstract

This research is motivated by the lack of students' ability in understanding concepts so that it has an impact on students in learning mathematics. Because the ability to understand concepts is the basis of understanding principles and theories with the aim of making it easier for students to understand concepts in subsequent material in studying mathematics. One of the factors of the lack of students' ability to understand concepts is math anxiety which has a large influence on student learning processes, both at school and on the student's environment. This study aims to find out how students' conceptual understanding abilities are viewed from mathematics anxiety in the implementation of learning in class VII SMP Negeri 1 Mazo. This type of research is descriptive research with a qualitative approach. This research was conducted at Mazo 1 Public Middle School with a total of 35 research informants. Data collection techniques through written tests, student math anxiety questionnaires, interviews and documentation. Based on the results of the study, it shows that there are students who have the ability to understand mathematical concepts with high anxiety, moderate and low anxiety. Students with high anxiety still cannot solve the test questions in a structured way due to a lack of focus and feeling a little anxious. students who are anxious are students who are good at completing test questions coherently, it's just that there are some that are not done. Students who are low on anxiety, students are able to solve test questions that are given in a structured way because students are calm and don't feel anxious when facing math problems, it's just that they can't finish up to the final result, so that this can have an impact on student learning. So in this case the ability to understand concepts with math anxiety is that the higher the level of students' math anxiety, the lower the students' ability to understand mathematical concepts. Conversely, the lower the students' math anxiety level, the higher the students' understanding of mathematical concepts.
