Abstract

The red ginger plant is a type of rhizome plant which is one of the spices that are needed in Indonesia. The number of requests for red ginger requires the right planting media composition. Charcoal husks and manure are often used as mixed materials, especially those that cultivate plants in the bottom or polybags. An important parameter in the farming system is Electrical Conductivity (EC), temperature and pH. The degree of acidity or pH of the soil is very influential on the growth of a plant with a value between 6.5 to 7.5. The room temperature for red ginger plants is good with a range of 22-35°C. The TDS meter value in PDAM water is good at 100 ppm but the smaller the TDS value the better the water conductivity. The results of the sample testing 1, 2 and 3 of the soil pH value are at 5.9 to 6.4, this has a large impact of plant nutrient not available, so that Plant growth is disrupted. The TDS value is in the value of 87 to 95 shows the conductivity of water during the trial period in good condition. The temperature value of the space is in the range of 20-34°C which the temperature value is in the right condition. Making IoT-Based Application in Red Ginger Plants can help find out the good value of water conductivity, room temperature and soil pH in planting red ginger plants that can be monitored through the application.

Abstract

Snails or with the Latin name Achatina fulica are soft-bodied animals with shells on their bodies. Snails can be found in Indonesia during the rainy season, but are quite difficult to find during the dry season. This is due to high temperature conditions and low air and soil humidity during the dry season, making it difficult for snails to survive. Therefore, a system is made that can see the physical condition of the environment and control it using fuzzy logic because snails can survive in a certain temperature and humidity range. To see the physical condition of the environment, this system uses a DHT22 sensor, a soil moisture sensor and a BH1750 sensor. The results of the sensor readings of air temperature, air humidity and soil moisture will be sent to a website which will later be processed using fuzzy logic and will receive a response in the form of an actuator activation time range in the form

Abstract

Mocaf (Modified Cassava Flour) is flour from cassava which is fermented by lactic acid bacteria. The growth temperature for lactic acid bacteria is 30°C-37°C with a fermentation time of 12-24 hours. In previous research, during 24 hours of fermentation at 33°C, mocaf flour produced the highest protein content of 12.87% without using a temperature stabilization system. The success of the fermentation process is indicated by a decrease in the pH value of the fermentation water to 4.5–5.0. In household scale producers, mocaf fermentation is still carried out traditionally at unstable temperatures. Therefore, a system is needed to monitor and control temperature automatically. In this research, the system that has been designed uses an ESP32 microcontroller as the system control center. The pH sensor is used to detect the pH value of water, the gas sensor is used to detect carbon dioxide gas (CO2) and the temperature sensor is used to detect the water temperature value. Peltier elements are used to lower the temperature and heaters are used to increase the temperature of the fermented water. In this research, a successful fermentation process with a pH value of around 5.0 could be achieved within ±12 hours at a temperature of 33°C, ±18 hours at a temperature of 43°C, and ±25 hours at a temperature of 23°C. In this study the mocaf fermentation process was completed in only ± 12 hours at a temperature of 33°C which is the ideal temperature for the growth of lactic acid bacteria.

Abstract

Compensation is an activity carried out by students outside class hours as a sanction for the student's absence from attending scheduled lectures. In this era, information is really needed, especially information on compensation in lectures. Initially compensation on digital telecommunications networks was still done manually or by coming directly to the admin to ask about compensation. But after this system is created, it will improve the compensation system on digital telecommunications networks. Students only need to access the website and no longer need to come to campus to find out information about compensation. The website has been designed in such a way to make things easier for students. This system is very useful for students because all compensation matters can be done via the website so it will be more effective for students. The problem with the Digital Telecommunication Network Study Program is that 84% of students have not compensated and only 16% of students have compensated. Based on these problems, development was carried out in the form of designing a web-based compensation information and registration system using biometric fingerprints for sending compensation agreements using a telegram bot. The information system used is a series of biometric systems with fingerprint sensor devices with FPM10A module, Telegram Bot, Arduino and ESP32 features and produces a system prototype that can provide information about compensation and compensation registration to polynema students so that it can make things easier for students of the Digital Telecommunication Network Study Program Malang State Polytechnic in paying compensation

Abstract

Pemancar siaran radio FM adalah salah satu sistem komunikasi nirkabel, bekerja rentang frekuensi 88-108 MHz membutuhkan sebuah filter bandpass untuk menghindari adanya interferensi dengan frekuensi yang berdekatan dengan pemancara radio. Jenis filter yang memiliki performansi cukup baik adalah filter dengan tingkat kecuraman yang cukup tinggi. Namun, untuk mendapatkan tingkat faktor kecuraman yang tinggi dengan menambah beberapa elemen. Maka, pada penelitian ini menambahkan rangkaian m-derived utnuk memberikan respon filter yang lebih curam tanpa menambahkan nilai elemen yang banyak. Tujuan penelitian ini mengetahui perbandingan daya pemancar tanpa filter, dengan bandpass filter, dan menggunakan bandpass filter m-derived. Hasil pengujian daya pancar tanpa filter sebesar 2 Watt, dengan menggunakan bandpass filter daya pancar sebesar 1,05 Watt, sedangkan dengan menggunakan bandpass filter m-derived daya pancar sebesar 1,4 Watt. Kesimpulannya pelemahan (insertion loss) pada Bandpass Filter sebesar 2,53 dB sedangkan pelemahan (insertion loss) pada BPF m-derived section sebesar 1,54 dB dengan menambahkan BPF m-derived section memperbaiki daya keluaran pemancar lebih besar 0,35 W atau 1,01 dB dibandingkan dengan pemancar yang menggunakan BPF tanpa m-derived. ABSTRACT FM radio broadcast transmitter is a wireless communication system, with frequency range of 88-108 MHz requires a bandpass filter to avoid interference with frequencies adjacent to radio transmitters. The type of filter that has a fairly good performance is a filter with a fairly high level of steepness. However, to get a high level of steepness factor by adding some elements. So, in this study, we added an m-derived circuit to provide a steeper filter response without adding a lot of element values. The purpose of this study is to compare the transmitter power without a filter, with a bandpass filter, and using an m-derived bandpass filter. The result of testing the unfiltered transmit power is 2 Watt, using a bandpass filter the transmit power is 1.05 Watt, while using the m-derived bandpass filter the transmit power is 1.4 Watt. In conclusion, the insertion loss in the Bandpass Filter is 2.53 dB, while the insertion loss in the BPF m-derived section is 1.54 dB by adding the BPF m-derived section to improve the transmitter output power by 0.35 W or 1 .01 dB compared to transmitters using BPF without mderived.

Oleh karena itu, diperlukan pemanfaatan sistem Mutiple Input Multiple Output (MISO) amplifier untuk meningkatkan kekuatan sinyal, memperluas jangkauan jaringan, dan meningkatkan daya transmisi melalui antena. Penelitian ini bertujuan menciptakan hardware komunikasi MIMO dan access point yang meningkatkan pengiriman dan penerimaan sinyal. Fokusnya adalah membandingkan pengaruh antena mikrostrip dan amplifier pada sistem access point serta menilai performansinya. Antena mikrostrip mampu bekerja pada frekuensi dual band: 2,4 GHz (2415.215 MHz) dan 5 GHz (5781.78 MHz). Untuk band 2,4 GHz memiliki gain sebesar 16,48 dB. Sedangkan untuk band 5 GHz memiliki gain sebesar 12,39 dB. Amplifier memiliki rata-rata gain 4,36 dB untuk 2,4 GHz dan 19,93 dB untuk 5 GHz. ABSTRACTWiFi is a wireless technology that is often used in modern communication networks such as between telephone or computer devices. However, one of the disadvantages of this technology is the quality of the signal strength of WiFi communication which can reduce the quality of data transmission. Therefore, it is necessary to utilise an antenna communication system to increase the beam power. Mutiple Input Multiple Output (MISO) is a model of installing signal transmitters to increase signal strength, expand network coverage, and increase transmission power through antennas. This research aims to create a MISO communication hardware connected access point that enhances the signal for sending and receiving data. The focus is on comparing the effect of microstrip antennas and amplifiers on the access point system and assessing their performance. The microstrip antenna is capable of working at dual band frequencies: 2.4 GHz (2415.215 MHz) and 5 GHz (5781.78 MHz). The 2.4 GHz band has a gain of 16.48 dB. The 5 GHz band has a gain of 12.39 dB. The amplifier has an average gain of 4.36 dB for 2.4 GHz and 19.93 dB for 5 GHz.
