Abstract

ABSTRACT Tidal swamp lands containing acid sulphate is easily become idle land, which can be fixed by reducing oxidation process of pyrite (FeS2). The pyrite oxidation causes disturbance on the growth and yield of rice plant. An experiment was conducted by means soil leaching in order to reduce accumulation of pyrites. The research had been conducted in Simpang Jaya village, Barito Kuala District in 2012 using a split plot design with three replications. As the main plot was leaching, and no leaching treatment, while as the subplot was soil tillage, i.e., 1) control, 2) weeds cleared without tillage, 3) soil tillage at a depth of 15 cm, and 4) soil tillage at a depth of 30 cm. The results showed that the leaching treatment combined with tillage at a depth of 15 cm or 30 cm increased the number of rice tillers, shoot dry weight, and number of panicles per hill, and number of seeds per hill, thus the leaching treatment was able to increase rice production.Keywords: acid sulphate, leaching, pyrite, tidal swamp land

Abstract

The purpose of this study is to produce valid and practical educational video media products for use in the learning process. This research is carried out using the type of research and development (R&D) to produce a product. This study aims to, 1) determine the level of media needs for cultural education video media of the Kajang tribe, 2) know how to design educational video media, 3) know the level of validity and practicality of educational video media. The product development model used, namely the ADDIE Model in Husni (2018) consists of several stages, namely: Analysis, Design, Development, Implementation, and Evaluation. This model is suitable for developing interactive media because this model specifically discusses each component described in detail. The data collection techniques used are Qualitative Descriptive Analysis and Qualitative Descriptive Analysis. The subjects in this study were 2 validators consisting of media experts and content or material experts, class X students totaling 34 students and 1 teacher response. The validation results show that the educational video media products developed are declared to be of good qualification.
