Authors: Setiawan A , Budiman A A , Sayuti A 
Published: March 2020

Abstract
Limitations and shortages of fresh water often occur problems especially for coastal communities, port areas and other areas with minimal water supply. The need and limitations of fresh water can cause distribution which is hampered due to lack of monitoring and distribution in the field, so that the distribution and distribution are evenly distributed. The purpose of this study is to overcome the problems that occur by designing and simulating tools that regulate the distribution of fresh water. The system works when the water flow sensor calculates the flow of water that passes through it and after reaching the maximum capacity previously set, the solenoid valve will automatically stop the distribution of water, so that every citizen who has the right to receive fresh water will get according to his daily allowance. In designing the simulation design there are several obstacles to the unavailability of several sensors needed, such as water flow sensors and solenoids for which we make alternative solutions by making logic C ++ algorithm in Arduino Uno R3.

Abstract
This study aims to determine the effect of predominant wind angle on the concentration of CO received by receptors (receptor position) due to the cement industry. This research was conducted in the surrounding area of the cement industry in Padang City. The sampling of CO concentration was undertaken at 3 sampling points, that is Unand Blok D Residence, Padang Besi Residence, and Batu Gadang Residence, that is representing of the receptor positions (α), i.e. 0°, 45° and 90°. In addition, sampling was also conducted at background point in Bukit Sungkai, Batu Busuk, Padang City. Sampling CO concentration at 4 sampling points using an impinger. The sampling of each location was done every hour for 24 hours of measurement (24 data per sampling point), with a total of 96 data. The results showed CO concentrations range between 124,502 and 287,292 μg/Nm3. The highest concentration was found at α 0° (Unand Blok D Residence) while the lowest concentration was located at α 90° (Batu Gadang Residence). Meanwhile, CO concentrations in the background point (Bukit Sungkai, Batu Busuk) is relatively lower than the three-sampling point above, ranging from 44.22 μg/Nm3 up to 74.13 μg/Nm3. The decrease in CO concentration on wind coming angle occurred from 0° to 45° by 13.79% and α 0° to 90° by 25.38%. This decrease happened by shifting α from 0° to 90°. This indicated that there is an effect of predominant wind angle direction towards CO concentration received by the receptor.

Published: March 2020

Abstract
The existence of infrastructure is very important to support economic development. The current infrastructure development has not considered much of the meaning of the development object. Research uses Levi Strauss structuralism approach. The revelation of meaning begins with tracing the surface structure which is composed of form and function aspects. The method of revelation of meaning begins with examining the syntagmatic relationships between dam and custom elements. The search for paradigmatic relations between the two surface structures is to be done in order to reveal the deep structure of the Rotiklot Dam. Meaning is obtained through the interpretation of deep structure. The paper concludes that the expression of the deep structure derived from the Rotiklot Dam is the balance and harmonization of the materialization of relations between the fields forming Rotiklot Dam. Finally, to reveal the deep structure of infrastructure with the case of the numinous unity in order to maintain reciprocity between humans and humans, humans and creators, and humans and nature.
