Abstract

Based on data from Central Bureau of Statistics in 2016 - 2020 soybean production deficit, the main factor is the decline in the quality of soybean seeds temperature and humidity sensitive. And so we need a system of monitoring and control of temperature and humidity container store soya beans. Wireless sensor network wireless technology that consists of a collection of sensor nodes distributed on a given area can support the communication between the sensor nodes using the system and sensor NodeMCU DHT11. This research was to analyze the WSN QoS monitoring system and temperature and humidity control soybean seed store container-based IOT using NodeMCU clients and coordinators are connected to an access point for sending data to the server in realtime. Tests carried out by putting the sensor node at 3 points with a distance variation of the coordinator and a data packet transmission interval. The test results obtained using a star topology indoor NLOS conditions optimal distance sensor node 3 which is 4 meters and the delivery interval 40s with packet loss value of 0-20%, delay 1.154 - 5,92s, jitter 0.241 to 7.57 ms, and throughput 66.32 bits / s. WSN protocol IOT uses MQTT NodeMCU and goes well with a low throughput value is 529.81 bps to 544.85 bps can still generate a delay kualiatas 200.33 to 270.83 ms and packet loss from 0 to 1.284% which is good. 92s, jitter 0.241 to 7.57 ms, and the throughput of 66.32 bits / s.

Abstract

Integrating logical and analytical thinking activities to support 21st century learning ability, into a learning activity at elementary and junior high school level becomes a challenge. One of them is less interesting learning media. One of the technologies that can be used to support exciting learning is block programming Alice and Scratch. This article aims to develop online training materials Logic and Algorithm utilize block programming scratch for level five elementary school and block programming Alice for level eight junior high school as eLearning content. The development of this research is carried out by Analysis-Design-Development-Implementation-Evaluation (ADDIE) development model. Initial products were reviewed and advised by 2 primary school teachers, 2 junior high school teachers. Product quality assessment is done based on content feasibility aspect, feasibility of presentation, language feasibility using Likert scale. The results data are then analyzed using the ideal scoring criteria to determine product quality. The results of the overall training content quality assessment show an average grade of 89.8 with good.

Abstract

Presence of students of the Master of Telecommunications Engineering Study Program majoring in Electrical Engineering Semarang State Polytechnic is currently still managed and carried out manually. This does not rule out the possibility of errors in managing data attendance and cheating students in faking their presence, and also with the development of science and technology that is currently completely automated. From this background, it was made the Presence Using RFID Based Raspberry Pi System where the PBM became Admin to be able to access all the attendance data of the S2 Telecommunications Engineering students. Student attendance recording is done by PBM by opening a MySQL database that has been created and stored, then processed and adjusted to existing student data as student ID. The end result obtained is a tool and system that are integrated automatically and also precisely, so that students are required to arrive on time so that they do not get the Compensation if they have passed the deadline and PBM admin can manage the recapitulation data through the website including student data, data lecturer, course data, room data, lecture schedule, attendance activities, and print reports in PDF format. The trial was carried out in the Computer Lab of the Semarang State Polytechnic Applied Science Master. The conclusion is that this tool and system is able to educate students to come and have a scheduled presence and can also record attendance automatically.

Abstract

Parking space is one of the important needs for vehicle owners.along with the increasing number of vehicles, especially in big cities have an impact on the difficulty of finding parking locations. Sometimes it takes a few minutes even hours just to find the location of available parking. This is the background of making Finding Parking. Application Finding Parking is an online parking search system based on the Internet of Things.on the parking location there are infrared sensors that aims to detect the presence of vehicles, data from existing sensors this parking location will be processed and sent to users who look for parking locations via Android to know the location of the nearest parking. The purpose of this Final Project is to help vehicle owners find available parking locations.Finding Parking application created by Waterfall method, Java programming language, MySQL database that is run by users through Android smartphone .Based on the tests that have been done can be obtained results that Finding Parking application is able to provide information to the owner of the vehicle regarding the availability of parking locations.

Abstract

Water environmental factors that greatly affect the survival and growth of catfish include temperature and water pH with pH range of 6.5-8 and temperature of 250C-300C. The monitoring and measurement are still done manually by catfish farmers to get the temperature and pH parameter values without knowing the exact value of these measurements. According to those problems, this final project provides an information system on monitoring the water quality of catfish pond to facilitate monitoring, namely by using a device that is remotely controlled in real-time, and contains sensors needed for measurement so that it can measure the parameters from a different place. Each node in each pond contains a measurement system using a DS18B20 temperature sensor and a SEN0161 pH sensor that can measure temperature and pH. The system is using a method with several stages, namely the stages of design, implementation and testing. The measurement results from the temperature sensor and pH sensor are displayed on the web page in the form of graphs and tables.
