Abstract

Almost every year, most of Grobogan Regency experiences drought which can affect various fields including agriculture, where some of the people are farmers. This article aims to analyze the comparison of the secondary crops of maize and green beans during the drought season in the villages of Banjardowo, Plosorejo, and Mayahan, Grobogan Regency. This study used survey research involving 20 respondents (farmers) from the three villages. Data collection techniques, namely, observation, interviews, respondent questionnaires and documentation. The results of the interview showed that the interviewee planted green beans as a staple crop in both the rice-paddy-secondary crops and the rice-crops-bero cropping pattern. Cultivating green beans in the rice-crops-bero pattern, the farmers of the three villages planted them on broken land (nelo: Java) because of the high level of drought. The results from 20 respondents were seen from 6 aspects: 1) suitability of plants in the dry season. 2) Planting on the ground that is broken (Nelo: Java). 3) relatively water efficient. 4) High Income. 5) Pest resistance. 6) Abbreviations of the harvest period, namely the average yield of green bean plants is 87.04% while corn is 52.04%. The conclusion of this research is that green beans are a suitable alternative crop to be planted in the dry season.

Abstract

Practical instructions for practical activities in computational physics courses have been successfully developed with material on the Laplace equation for temperature distribution. This research aims to produce practical instructions and determine the characteristics, feasibility, and responses of students to practical instructions for computational physics on the Laplace equation. The research design used is development research or R&D (Research and Development) which was modified from Sugiyono. The research was carried out at the Computer Laboratory of PGRI University Semarang with Physics Education study program students as research subjects. The research results show that the computational physics practicum instructions developed have the criteria "Very Feasible" based on validation from three computational physics experts with respective percentages of 96%, 99% and 93%. The characteristics of this computational physics practical guide are that it is prepared using computational thinking techniques and written using structured documents (LaTex), presented explicitly and equipped with algorithms, solving with two different scenarios (iterations and matrices) in one case as well as writing coding. uses the latest software (Python) and is equipped with algorithms. This computational physics practical instruction received a very good response from students with a percentage of 87% in the initial trial and 88% in the usage trial.
