Abstract

Research on Schmidt-Ferguson climate classification and Thiessen polygon mapping in Bojonegoro Regency, East Java has been carried out based on rainfall data during the 2016–2022 period. The aim of this research is to determine climate types according to the Schmidt-Ferguson classification and the spatial distribution of climate types using the Thiessen Polygon method in Bojonegoro Regency, East Java. This process begins with collecting rainfall data, coordinates and height of rain posts. From the analysis results obtained, Bojonegoro Regency has 4 types of climate based on the Schmidt-Ferguson classification, namely: Very Wet (A), Wet (B), Slightly Wet (C) and Dry (F). While based on Thiessen Polygon mapping, type A distribution has an area of 323.02 km2, climate type B classification covering an area of 962.22 km2, Classification of climate type C covering an area of 669.95 km2 and climate type F classification covering an area of 374.07 km2.

Abstract

The design of a light intensity measuring instrument using the BH1750 sensor based on the ATMega328P microcontroller has been successfully created. The results of light intensity data are measured by using the BH1750 sensor which receives a data signal in the form of light intensity. In order to get results that are in accordance with the reference tool, the design of a light intensity measuring instrument by using the BH1750 sensor based on the ATmega328P microcontroller is carried out in the Electronics and Instrumentation Laboratory and Computing Laboratory, Physics Study Program, FMIPA, Udayana University, Jimbaran, Bali. Then the results of the design of tool and reference tool processed into graphical form and proven by employing a linear regression equation. The measurement results of light intensity are displayed on a 16x2 LCD. The test results of the design tool against the reference tool shown that the level of accuracy of the design tool is relatively high.
