Abstract

Abstract. Online learning is a technology learning model to complement face-to-face (direct) learning. It is hoped that students can still understand what the teacher says even though it is through online media. Learning challenges are a challenge for teachers so that the material can be conveyed properly, especially in the ability of students' mathematical problems. Mathematical problem skills are very useful for students, not only in solving math problems but also solving problems in everyday life. Problem ability is not something that is easily found by students so that students must train to develop this ability. For the ability to develop this, the learning process and strategy that is applied must be able to help understand the problem, plan for problem solving, find solutions and be able to conclude from solving the problem. One learning approach that can make students active in learning is the contextual approach. This experimental research aims to see the effectiveness of bold learning with a contextual approach to students' mathematical problem abilities. This study used a posttest only control group design. The population of this study were all students of class VIII MTs. Son and Daughter of Simo in the 2020/2021 school year. Through probability sampling techniques, classes VIII D and VIII G were selected as research samples. The research data were obtained from the mathematical problem ability test. The results showed that the most effective level in dealing with mathematical problems of students with a bold learning model with a contextual approach strategy was better than conventional learning. Keywords: Mathematical problem solving abilities, contextual approach, online learning. Abstrak. Pembelajaran daring atau online adalah salah satu model pembelajaran berteknologi untuk melengkapi pembelajaran tatap muka (langsung). Diharapkan siswa masih bisa memahami apa yang disampaikan oleh guru walaupun melalui media online. Pembelajaran daring menjadi tantangan tersendiri bagi guru agar materi bisa tersampaikan dengan baik utamanya dalam kemampuan pemecahan masalah matematis siswa. Kemampuan pemecahan masalah matematis sangat berguna bagi siswa, tidak hanya dalam memecahkan masalah matematika tapi juga memecahkan masalah dalam kehidupan sehari-hari. Kemampuan pemecahan masalah bukan merupakan suatu hal yang mudah didapati oleh siswa sehingga siswa harus melatih untuk mengembangkan kemampuan tersebut. Untuk mengembangkan kemampuan tersebut, maka proses dan strategi pembelajaran yang diterapkan haruslah dapat membantu siswa memahami masalah, merencanakan penyelesaian masalah, menemukan solusi dan dapat menarik kesimpulan dari penyelesaian masalah tersebut. Salah satu pendekatan pembelajaran yang dapat membuat siswa aktif dalam pembelajaran adalah pendekatan kontekstual. Penelitian eksperimen ini bertujuan untuk mengetahui efektivitas pembelajaran daring dengan pendekatan kontekstual terhadap kemampuan pemecahan masalah matematis siswa. Penelitian ini menggunakan posttest only control group design. Populasi penelitian ini adalah seluruh siswa kelas VIII MTs. Putra-Putri Simo tahun pelajaran 2020/2021. Melalui teknik probability sampling terpilih kelas VIII D dan VIII G sebagai sampel penelitian. Data penelitian diperoleh dari tes kemampuan pemecahan masalah matematis. Hasil penelitian ini menunjukkan bahwa tingkat efektivitas kemampuan pemecahan masalah matematis siswa model pembelajaran daring dengan strategi pendekatan kontekstual lebih baik dibandingkan dengan pembelajaran konvensional. Kata Kunci: Kemampuan pemecahan masalah matematis, pendekatan kontekstual, pembelajaran daring.

Abstract

Latar belakang penelitian adalah rendahnya kemampuan siswa dalam memecahkan masalah geometri. Penyebab dari rendahnya kemampuan tersebut adalah kurangnya pemahaman konsep dan keterampilan geometri siswa. Sehingga diperlukan kreativitas guru dalam proses belajar mengajar yang lebih menekankan pada kemampuan siswa dalam pemecahan masalah materi geometri. Model pembelajaran Van Hiele merupakan model yang disesuaikan dengan tahapan berpikir siswa, sehingga tepat diterapkan dalam pembelajaran geometri. Tujuan dari penelitian ini adalah untuk mengetahui keterlaksanaan pembelajaran, respon dan hasil belajar siswa dengan menggunakan pembelajaran Van Hiele dalam rangka mendukung kemampuan pemecahan masalah geometri. Penelitian ini menggunakan jenis penelitian kuantitatif dengan desain penelitian “one shot case study”. Instrument yang digunakan dalam penelitian adalah RPP, lembar observasi, angket respon siswa, dan soal tes pemecahan masalah. Populasi penelitian adalah siswa kelas VIII SMP NU Miftahul Huda Karangrejo dengan sample kelas VIII B. Data yang dianalisis yaitu data lembar keterlaksanaan pembelajaran, angket respon siswa, hasil belajar siswa dan hasil tes pemecahan masalah. Dari analisis data diperoleh bahwa hasil keterlaksanaan pembelajaran Van Hiele terlaksana dengan baik. Respon siswa pada pembelajaran Van Hiele menunjukkan positif. Hasil belajar siswa kelas VIII B SMP NU Karangrejo juga menunjukkan baik. Dan hasil keefektifan menunjukkan bahwa pembelajaran Van Hiele mampu mendukung pemecahan masalah geometri.

Abstract

Abstract. The construction sector is one of the drivers of national economic growth, contributing 10.6% to the National GDP. The capitalization value of the construction sector continues to increase from year to year due to an increase in the industrial sector in the private sector and infrastructure acceleration programs launched by the government in several provinces. However, this has led to a lack of equitable distribution of infrastructure development in several other provinces. To help the government carry out equitable infrastructure development, which can then help the national economy, an analysis is needed to find out what factors affect the construction value of each province in Indonesia. The relationship between the value of the construction and the factors that influence it can be determined by regression analysis. The regression analysis method used in this study is Poisson regression and negative binomial regression. Negative binomial regression is performed specifically to overcome overdispersion in Poisson regression. After the analysis, the results of the factors that have a statistical influence on the value of construction in Indonesia (NK) are the number of workers in each province (JTK) and the number of construction companies in each province (JP) with a pseudo R2 value of 0.978 or 97.8%.

Abstract

Village funds are funds originating from the State Revenue and Expenditure Budget which are used for villages through the Regional Revenue and Expenditure Budget. Management of village funds must be transparent and orderly. To determine the allocation of village funds to the total population, the number of poor people, the area of ​​the region and the geographic poverty index. The method used to analyze these factors is multiple regression analysis. From the results of the analysis carried out, it is found that there is a significant influence between the total population, the number of poor people, the area and the geographic poverty index on the allocation of funds.
