Abstract

This study was aimed to describe ability of prospective student educators in using computer technology to develop mathematics learning multimedia. The ability was used to develop Power Point multimedia and Adobe Flash multimedia. This study was descriptive research with 27 prospective student educators as a subject. Researcher was main instrument assisted product evaluation rubric and questionnaire. The result showed that the average of ability of prospective student educators in using computer technology was in good category. The average score were 77,59  in using Power Point multimedia and 74,54 in using Adobe Flash multimedia. The ability was sufficiently to be used in learning and teaching. From the product analyzed and questionnaire, we found that the ability were not maximal because there were many tools untapped primarily in Adobe Flash. Unfamiliar yet in used also became a factor that affected the ability of prospective educators in using computer technology. Keywords: The ability in using computer technology, mathematics learning multimedia, prospective educators

Abstract

Over the past century, there has been a dramatic increase in worldwide research.  However, these rapid increases are also arising problems or difficulties faced by the university students. Therefore, this research was carried out to reveal the types of those difficulties faced by students of STKIP Pacitan PGRI in solving the two-factor experiment tests in the design of experiment subject and the factors which cause these difficulties.  The researcher opted the qualitative descriptive design to the qualified research findings. Moreover, the samples, 15 students, were randomly taken from the total population or 93 students who attended the lectures. The technique of collecting the data employed both written test and interview of the researched subject. Based on the research findings, the students were difficult in determining the source of variance (SV), the degrees of freedom (df), the Expected Mean Square (EMS), the F value. Briefly speaking, the students were difficult in the process of calculating. While, the factors that caused the difficulties were in distinguishing the state of R, drawing a conclusion from all these factors, determining the number of r (replicate), determining the removed part from EMS, being careless in equalizing the line of numerator and denominator candidate, being unable to develop formulas, and careless in the calculation. Keywords: kesulitan, rancangan, faktorial

Abstract

Penelitian korelasional ini bertujuan untuk mengetahui apakah terdapat korelasi positif antara gaya kognitif field dependent dan tingkat pemahaman konsep matematis pada siswa yang dikenai model pembelajaran langsung dan STAD. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri di Lampung Selatan. Pengambilan sampel dilakukan dengan teknik cluster random sampling sehingga diperoleh dua kelas sampel penelitian. Metode tes diterapkan untuk mengumpulkan data. Instrumen penelitianini berupa GEFT dan tes pemahaman konsep matematis pada materi persamaan garis lurus. Berdasar pada hasil pengujian hipotesis, diperoleh simpulan bahwa (1) terdapat korelasi positif antara gaya kognitif field dependent dan tingkat pemahaman konsep matematis pada siswa yang dikenai model pembelajaran langsung dan (2) tidak terdapat korelasi positif antara gaya kognitif field dependent dan tingkat pemahaman konsep matematis pada siswa yang dikenai model pembelajaran STAD. Hasil ini berimplikasi bahwa model pembelajaran mempengaruhi tingkat pemahaman matematis siswa yang bergaya kognitif field dependent.

Abstract

This study aims to predict the number of poor in Indonesia for the next few years using a triple exponential smoothing method.The purpose of this research is the result of the forecast number of poor people in Indonesia accurate forecast results are used as an alternative data the government for consideration of government to determine the direction of national poverty reduction policies. This research includes the study of literature research, by applying the theory of forecasting to generate predictions of poor people for coming year. Furthermore, analyzing the mistakes of the methods used in terms of the count: Mean Absolute Deviation (MAD), Mean Square Error (MSE), Mean absolute percentage error (MAPE) and Mean Percentage Error (MPE). The function of this error analysis is to measure the accuracy of forecasting results that have been conducted.These results indicate that the number of poor people in 2017 amounted to 24,741,871 inhabitants, in 2018 amounted to 24,702,928 inhabitants, in 2019 amounted to 24,638,022 inhabitants and in 2020 amounted to 24,547,155 people. The forecasting results show an average reduction in the number of poor people in Indonesia last five years (2016-2020 years) ranges from 0.16 million. Analysis forecasting model obtained an mean absolute deviation (MAD) obtained by 0.246047. Mean squared error (MSE) of forecasting results with the original data by 1.693277. Mean absolute percentage error (MAPE) of 3.040307% and the final Mean percentage error (MPE) of 0.888134%.Kata Kunci: Forecasting, Triple Exponential Smoothing

Abstract

Tujuan penelitian ini adalah meningkatkan kinerja dosen matematika pada proses perkuliahan melalui  kegiatan lesson study dalam pelaksanaan pembelajaran. Penelitian ini merupakan penelitian tindakan  yaitu menerapkan lesson study untuk meningkatkan kinerja dosen matematika. Metode pengumpulan data yaitu observasi terhadap dosen model dalam perkuliahan, metode angket dan wawancara mendalam. Penelitian ini dilaksanakan di sebuah Sekolah Tinggi Manajemen  dan Ilmu Komputer di Surakarta. Pelaksanaan penelitian dimulai bulan Oktober – November 2016 sebanyak dua siklus penelitian. Subjek dalam penelitian ini adalah 4 dosen dengan keahlian  matematika. Instrumen yang digunakan dalam penelitian ini adalah lembar observasi, pedoman wawancara dan angket tertutup tentang respon mahasiswa setelah dosen mengajar. Metode analisis data menggunakan pendekatan proses siklik yakni data dianalisis sejak tindakan pembelajaran dilaksanakan (sejak dari plan-do-see), dikembangkan selama proses pembelajaran berlangsung sampai diperoleh pembelajaran yang berkualitas/professional. Metode analisis data ini terdiri dari tiga langkah yaitu; reduksi data, penyajian data dan verifikasi, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa dengan implementasi kegiatan lesson study dapat meningkatkan kinerja dosen matematika pada proses perkuliahan. Kata Kunci: Lesson study, Kinerja Dosen, matematika

Abstract

Aircraft has  became the best choice for long distance traveling because it has shortest travel time than any other transportations. Moreover, in recent years, aviation industries have competed for providing low cost flight so that it can also be enjoyed by middle class society. Thus escalate the popularity of aircraft as economical carrier. Knowing the volume of passengers in advance will help government and related institutions to effectively providing facilities. The volume of passengers can be predicted using classic model such as double exponential smoothing model which is simpler and has high accuracy. However, the randomness of Indonesian passenger volume data cause double exponential smoothing (DES) cannot follow both data pattern and data trend. Moreover, classic model often encounters overfitting where the prediction is bigger than the actual data. Therefore, we employed Grey Method applied on DES (GDES) to overcome this problem. GDES enabled the researcher to perform better data fitting because it would generate smoothing curve which showed clearer trend. As the result, although GDES fitting curve had higher error measurement (MSE) than DES, the forecasting result of GDES was more precise than DES. Keyword: Double Exponential Smoothing, Grey Method, Levenberg-Marquardt
