Abstract

In this technological world, mechanical engineering is inseparable from the existence of a tool and machine that plays an important role in everyday life such as agricultural machinery. This study aims to determine the effect of the type of thresher material, variations in the number of thresher teeth, grain quality, maximum capacity. The method used in this research is literature study, direct observation or observation. Based on the results of measurements and testing with three variations of 3 different thresher teeth materials, the required data is obtained and the data is processed and calculated that the material of bolts, iron bolt, and per leaf, is increasing from 3 different variations in the level of thresher teeth crookedness the bolt material reaches 60o and in the molten iron thresher the bending level rises to 63o whereas in the iron threshold of iron teeth per leaf the smallest is 32o. After conducting direct field testing we can find out that the quality of rice in the variation of the number of thresher teeth 36 thresher teeth reached 40.2 kg, the variation of 40 reached 43.7 kg, and the variation of 44 thresher teeth reached 44.5 kg. Variation 44 teeth thresher has the highest results.

Abstract

Spermatophyta diversity in Indonesia includes a high category of rank to two in the word. Higher plants are plants that have distinguished roots, stems and leaves, and have flowers as a means of reproduction. The objectives of this research were 1) to determine the species of Spermatophyta diversity around Lake Asam Suoh, West Lampung Regency, 2) to determine the status of the biodiversity around Asam Lake Suoh, West Lampung Regency, 3) to determine the diversity index and dominance index) to find out the research results of the Spermatophyta plants in Asam Lake Suoh, West Lampung Regency, it can be used as material for the encyclopedia. This research uses purposive sampling at each station. By using these 4 stations, it is hoped that it can describe a state of Asam Lake Suoh regarding the diversity of Spermatophyta. The research data showed that there were 21 species of plants included in tall plants or Spermatophyta. The results of the calculation of the Spermatophyta Diversity Index around the Asam Lake Suoh, West Lampung is H1 1, indicating that the diversity of species in a transect site is small or low. The results of the calculation of the Dominance Index of Spermatophyta around the Asam Lake Suoh, West Lampung is 0.00 <C 0.50, indicating that the Dominance Index is low. Material validation officials get the 86% score and experts get the 84%, which means that an enciclopedia into category is highly worth using.
