Abstract

The purpose of this study was to determine the difference and level of problem solving ability of students between before and after applying learning with PjBL-STEM on disaster mitigation sub-materials. This research is an experimental research with one group pretest-posttest research design. The data collection methods used are test and documentation methods. The instruments used include pretest and posttest. The data were analyzed descriptively quantitatively. The results obtained are the application of PjBL-STEM on disaster mitigation sub-materials can improve students' problem solving skills. This is indicated by the results of the t-Test which shows the difference in results between before and after the application of PjBL-STEM, as well as the results of the N-Gain test of 0.57 with a moderate category. The level of students' problem solving abilities after implementing PjBL-STEM as a whole is in good criteria. The highest level of students' problem solving abilities is in the indicator of understanding the problem, while the lowest level is in the indicator of devising a plan.

Abstract

Abstrak. Studi ini bertujuan untuk melakukan inovasi terkait herbisida organik alternatif Roundup sebagai pengendali gulma di Kawasan pertanian Desa Kepunduhan. Sampai saat ini, metode pengendali gulma yang masih sering dilakukan adalah dengan menggunakan herbisida. Dari sekian banyak jenis merek herbisida, Roundup menjadi merek herbisida yang dipilih oleh hampir keseluruhan petani di Desa Kepunduhan. Herbisida organik alternatif Roundup ramah lingkungan merupakan sebuah inovasi oleh mahasiswa UNNES GIAT 5 yang melaksanakan program KKN di desa Kepunduhan dalam membantu menciptakan metode baru dalam penggunaan herbisida. Hasil penerapan inovasi ini menunjukkan dapat membantu petani dalam mengatasi  masalah gulma tanpa merusak lingkungan dan dapat mengurangi dampak negatif herbisida sintetik.Abstract. This study aim to present the results of innovations related to the alternative organic herbicide Roundup as weed control in the agricultural area of Kepunduhan village. Until now, the method of weed control that is still often done is to use herbicides. Of the many types of herbicide brands, Roundup is the herbicide brand chosen by almost all farmers in Kepunduhan village. Roundup alternative organic herbicides are environmentally friendly is an innovation by UNNES GIAT 5 students who carry out KKN programs in Kepunduhan village in helping to create new methods of herbicide use. The results of the application of this innovation show that it can help farmers overcome weed problems without damaging the environment and can reduce the negative impact of synthetic herbicides.Keywords : Herbicide; Weed; Weed Control
