Abstract

Dry land is productive land that can operate all year round, but with minimal water availability it is one of the obstacles for chili farmers. Therefore, the right solution for this problem is by applying drip irrigation techniques. The purpose of this research was to design and test the performance of the design on chili cultivation in dry land. This study used an experimental method with a direct experimental design on community agricultural land, by making 3 treatment groups, namely P1: surface drip irrigation, P2: subsurface drip irrigation, and P3: open channel irrigation. In this study, the parameters to be studied were designing and conducting performance tests on emitter discharge, water drop uniformity, and wetted areas. The results showed that the drip irrigation design consisted of several components, including primary reservoirs, secondary reservoirs, emitters and pressure regulators. The results of the performance test of the drip irrigation technique design can be said to be feasible to apply based on the discharge value and the drop uniformity coefficient, and the growth of chili plants, both with subsurface and above-surface drip irrigation techniques, does not have a significant effect. So it can be concluded that the method of providing water with subsurface and above-surface irrigation is both said to be effective and efficient

Abstract

The purpose of this study is to describe the effectiveness of teaching with the teaching model search, solve, create, and share (SSCS) regarding students’ achievement and mathematics learning motivation.This research was quasi-experimental with the non-equivalent control group design. The population was all students of class VIII SMP Muhammadiyah Banguntapan consisting of five classes. The sample taken at random consisted of two classes: classes VIII-D dan VIII-E. Class VIII-D was taught by using the model conventional, while class VIII-E was taught by using the SSCS teaching model. The data were analyzed by using a multivariate test Hotelling’s T2, MANOVA test. Each analysis regarding at the significance level of 5%. The results of the study show that: (1) the SSCS model is effective in terms of mathematical reasoning and learning motivation, while the conventional model is not effective in terms of student achievement and learning motivation; and (2) there is a difference in effectiveness between the SSCS model and the conventional model in terms of mathematical reasoning and learning motivation. ABSTRAKPenelitian ini bertujuan untuk mendeskripsikan: (1) keefektifan model SSCS ditinjau dari penalaran matematis dan motivasi belajar siswa, dan (2) mengetahui apakah terdapat perbedaan keefektifan antara model SSCS dan model konvensional ditinjau dari penalaran matematis dan motivasi belajar siswa setelah diberikan perlakuan. Penelitian ini merupakan penelitian eksperimen semu dengan desain kontrol grup non-ekuivalen. Populasi penelitian yaitu seluruh siswa kelas VIII SMP Muhammadiyah Banguntapan yang terdiri dari lima kelas. Sampel penelitian diambil dua kelas secara acak, yaitu terambil kelas VIII-D dan VIII-E. Kelas VIII-E diberikan perlakuan model SSCS, sedangkan kelas VIII-D diberikan berupa model konvensional. Kriteria Uji hipotesis yang digunakan yaitu data dianalisis secara multivariat menggunakan uji T2 Hotteling’s. Instrumen penelitian terdiri dari tes penalaran matematis dan angket motivasi belajar siswa. Hasil penelitian menunjukkan bahwa: (1) model SSCS efektif ditinjau dari penalaran matematis dan motivasi belajar siswa, sedangkan model konvensional tidak efektif ditinjau dari penalaran matematis dan motivasi belajar siswa; dan (2) terdapat perbedaan keefektifan antara model SSCS dan model konvensional ditinjau dari penalaran matematis, dan motivasi belajar siswa.
