Abstract

Pendidikan pada dasarnya merupakan proses untuk membantu manusia dalam mengembangkan dirinya sehingga mampu menghadapi setiap perubahan yang terjadi. Untuk memperlancar proses pendidikan diperlukan suatu wadah atau lembaga yang disebut sekolah. Sekolah dapat mendorong pertumbuhan dan perkembangannya kearah suatu tujuan yang dicita-citakan dalam pendidikan. Matematika adalah ilmu deduktif, aksiomatik, formal, hierarkis, abstrak, bahasa simbol yang dapat digunakan untuk mengatasi persoalan-persoalan dunia nyata. Matematika juga dapat membentuk pola pikir orang yang mempelajarinya menjadi pola pikir matematis yang sistematis, logis, kritis dengan penuh kecermatan. Namun, guru dalam mengajarkan matematika tidak bervariasi yang membuat pembelajaran matematika kurang bermakna dan kurang menarik bagi siswa. Oleh karena itu, dalam menanggapi masalah tersebut diterapkan program kerja kelas cermat (KECE) sebagai suatu kegiatan yang merupakan solusi dalam meningkatkan pengetahuan dasar matematika siswa SD Inpres 4/82 Jompie. Metode mengajar yang digunakan adalah metode pengajaran yang interaktif dan berbasis masalah yang melibatkan siswa secara aktif. Hasil yang telah dicapai melalui upaya pengajaran matematika yang efektif di SD Inpres 4/82 Jompie ini mencakup peningkatan pemahaman konsep matematika, keterampilan berpikir kritis yang lebih baik, peningkatan rasa percaya diri, dan keterkaitan yang lebih kuat dengan kehidupan sehari-hari. pendidikan matematika yang berkualitas dapat diakses oleh semua siswa, membantu mereka membangun fondasi kuat dalam matematika, dan meraih kesuksesan akademik yang lebih besar di masa depan.

Abstract

The progress of a nation depends on the quality of its human resources. One of the efforts to improve and develop the quality of human resources (HR) is quality education. Education is a very important tool for human survival. One of the problems that has become a major issue is the lack of equitable distribution of education. Therefore, in response to various obstacles in the implementation of education in Indonesia, students in Real Work Lecture (KKN) activities as a form of community service create a work program with the theme of tutoring houses. The method of implementation in this tutoring house program uses a direct approach method, namely conducting learning outside of school hours. The teaching method used is by using a game system. The tutoring program has a very important role in helping the children of Jompie Village achieve academic success and overcome learning difficulties. the tutoring program can be an effective tool in helping students achieve their academic potential. This is important in preparing them for a successful and fulfilling future.

Abstract

Indonesia is one of the largest nickel exporting countries in the world, with the increasing demand for electric vehicles making nickel a target for producers. The increase in nickel demand makes it necessary to increase the observation of nickel prices to maintain the sustainability of the mining industry and economic growth. The purpose of this study is to forecast the price of Indonesia's nickel market using the GARCH method. The GARCH method is one of the methods used in time series data modeling that identifies heteroscedatic effects. The steps taken are to analyze the training data, check the stationery, estimate the parameters, and test the diagnostic model, then the best ARIMA model is selected based on the smallest AIC value, namely ARIMA (0,1,1). The residual values of the best ARIMA models are then used to determine the GARCH model. The best GARCH model obtained is GARCH (0.1) with an AIC value of 19.04061. Furthermore, forecasting was carried out using the GARCH model (0.1) and comparing the forecast results with the testing data to obtain MAPE values. The MAPE value obtained is 17.67014 % which shows that the GARCH model (0.1) has good forecasting accuracy, so this model is quite feasible to be used in forecasting the price of Indonesia's nickel market.
