Abstract

Rice is one of the most important cultivated plants in human civilization. One of the most important post-harvest processes is drying. Therefore, we need a drying process with an artificial heat source that can be adjusted to achieve constant heat according to the temperature characteristics of the rice. By applying the Fuzzy-MIMO control system, rice drying is expected to work quickly without damaging the rice foam. Fuzzy-MIMO system is translated into a rule based on the fuzzy algorithm that has been created. The fuzzy-MIMO method used is the Sugeno method with input temperature errors and humidity errors and outputs in the form of heat and wind gusts. The temperature sensor used has an error factor of 3.61%. The expected control system is a heating system and a motor to regulate the wind gusts in the drying chamber. The total drying time produced is 240 seconds with a moisture content of 15.2%. Drying time is influenced by the initial moisture content of rice.

Abstract

Penelitian ini bertujuan mengetahui pengaruh penambahan variasi Apar Poweroil TO 20 terhadap karakteristik fisika yaitu massa jenis dan viskositas kinematik, pada campuran minyak kemiri sunan dengan penambahan BHT, serta mengetahui persentase dari tiga bahan yaitu minyak kemiri sunan, BHT, dan Apar Poweroil TO 20 dari hasil pengujian untuk mendapatkan komposisi dengan karakteristik yang baik. Dimana satandar isolasi cair transformator untuk massa jenis 0,8957 gram/cm3, viskositas kinematik 40 cSt, dan tegangan tembus 30 kV/2,5mm. Pada penelitian terdapat 4 sampel dengan variasi penambahan Apar Poweroil TO 20 sebanyak 5%, 10%, 15%, dan 20%. Dari hasil pengujian karakteristik fisika yaitu pengujian massa jenis dan viskositas kinematik, dapat diketahui bahwa penamhan variasi Apar Poweroil TO 20 pada sampel campuran minyak kemiri sunan dengan BHT dapat menurunkan nilai massa jenis maupun viskositas kinematik yaitu setiap penambahan Apar Poweroil TO 20 sebesar 5% mampu menurunkan nilai massa jenis sebesar 0,007 gram/cm3 dan menurunkan nilai viskositas kinematik sebesar 3,48 cSt. Dimana hasil pengujian massa jenis dari penambahan Apar Poweroil TO 20 sebesar 5% memiliki nilai 0,8605 gram/cm3, penambahan 10% nilai massa jenis 0,8551 gram/cm3, penambahan 15% nilai massa jenis 0,8461 gram/cm3, dan penambahan 20% nilai massa jenis 0,8397 gram/cm3. Hasil pengujian viskositas kinematik yaitu pada penambahan persentase Apar Poweroil TO 20 sebesar 5% memiliki nilai 20,70 cSt, penambahan 10% memiliki nilai 17,98 cSt, penambahan 15% memiliki nilai 13,58 cSt, penambahan 20% memiliki nilai 10,49 cSt. Dari data hasil pengujian untuk nilai perhitungan korelasi massa jenis memiliki hubungan negatif yaitu – 0,99 dan pada pengujian viskositas kinematik memiliki hubungan negatif yaitu – 1,06. Untuk nilai tegangan tembus yang didapat dari perhitungan secara matematis, maka penambahan Apar Poweroil TO 20 mampu meningkatkan nilai tegangan tembus dari bio minyak tafo dan juga mampu memperbaiki karakteristik fisika. Penambahan Apar Poweroil TO 20 dapat memperbaiki karakteristik fisika pada bio minyak trafo. Diharapkan dengan hasil pengujian tersebut minyak kemiri sunan dengan penambahan BHT (Butylated Hydroxytoulene) bisa dijadikan alternatif bahan baku isolasi cair untuk transformator daya 150 kVA.

Abstract

Daerah Aliran Sungai (DAS) merupakan satu kesatuan ekosistem yang kompleks. Keberadaan ekosistem mempengaruhi sistem aktivitas mahluk hidup didalamnya. Salah satu peran penting ekosistem DAS adalah mengatur siklus hidrologi.Apabila ekosistem DAS terganggu maka akan berpengaruh terhadap siklus hidrologi dan dampaknya bagi masyarakat di sepanjang DAS. DAS Kapuas merupakan daerah aliran sungai terpanjang di Indonesia dengan panjang aliran sungai mencapai 1143 km membentang dari Kabupaten Kapuas Hulu hingga Kabupaten Mempawah dan Kota Pontianak di Hilir. Dinamika ekosistem pada DAS Kapuas seiring dengan perkembangan aktivitas perkebunan monokultur dan juga dinamika iklim menjadikan ancaman bahaya pada DAS Kapuas Meningkat. Bencana yang dipicu oleh aspek hidrometeorologi telah menjadi satu bencana rutin yang harus dihadapi oleh masyarakat pada sepanjang DAS. Wilayah dengan potensi ancaman bencana multibahaya sedang hingga tinggi terdapat pada daerah-daerah tengah dan hilir DAS yang mendapatkan intervensi manusia. Bencana yang memberikan kontribusi terbesar adalah bencana banjir. Kawasan permukiman di sepanjang aliran Sungai Kapuas dan anak-anak sungainya merupakan kawasan yang paling rentan terdampak bencana banjir tersebut.

Abstract

Sistem monitoring greenhouse adalah alat yang bekerja untuk memantau dan mengamati kondisi di dalam greenhouse baik suhu, intensitas cahaya, kelembaban udara dan kelembaban tanah. Sistem monitoring ini terhubung secara wireless dengan menggunakan teknologi Zigbee dan terhubung dengan aplikasi IoT (Internet of Things) open-source yaitu thingspeak menggunakan jaringan seluler. Penelitian ini dilakukan untuk menguji dan menganalisis kinerja dari aplikasi IoT ketika dijalankan menggunakan jaringan seluler untuk mengetahui pengaruh dari kekuatan penerimaan sinyal terhadap delay, packet loss dan Throughput. Berdasarkan hasil pengujian ditemukan bahwa standar jaringan yang digunakan hanya mempengaruhi banyaknya TCP Error pada jaringan 3G dibandingkan jaringan 4G. Tetapi standar jaringan tidak mempengaruhi kinerja dari pengiriman data jika dilihat dari sisi delay yang berada diantara 0.5 ms sampai dengan 1.5 ms di kedua kondisi, packet loss yang hanya terjadi 1 kali dari seluruh 6 percobaan yang dilakukan dengan jumlah packet loss hanya sebesar 2%, dan throughput yang relatif sama diantara 9.7 sampai dengan 22 kbit/s. Sedangkan kekuatan sinyal atau besar dari nilai RSRP (Reference Signal Received Power) tidak mempengaruhi jumlah TCP Error yang berada diantara 1 sampai 4 error di seluruh kondisi dan tidak mempengaruhi packet loss dimana packet loss tidak terjadi di seluruh kondisi pengujian. Nilai RSRP hanya mempengaruhi delay dan throughput dan hanya pada kondisi low dimana pada kondisi sinyal low, terjadi peningkatan delay dari rata-rata 1 ms pada kondisi high dan moderate menjadi rata-rata 1.5 ms pada kondisi low, dan throughput yang berada diantara 10 sampai 16 kbit/s pada kondisi high dan moderate menjadi 6 sampai 15.4 kbit/s pada kondisi low.

Abstract

Everyone must have experienced something called illness. A disease in the human body can be caused by external factors such as pathogens or internal dysfunction. In a broader sense, a disease also includes injuries, disorders, disabilities, infections and syndromes. Among the various infections that exist in the human body, acute respiratory infections (ARI) are the most common diseases that affect all individuals regardless of age or gender, especially this virus that attacks the respiratory tract or respiratory diseases that virus spreads very quickly. . With this, the world health agency or known as the WHO (World Health Organization) has set several standards that can help deal with problems in the world. Therefore, we need equipment that helps check patients regularly and performs an early diagnosis so that when entering the patient's room, medical personnel have prepared themselves with some equipment that is by the patient's classification. This study will focus on the classification process in real-time on sensors installed in patients using machine learning decision trees as the classification method. Then, the classification results can be shown directly that the respiratory disease patients fall into a predetermined class.

Abstract

This Android-Based Solar Panel Current and Voltage Monitoring System is intended to be implemented properly by companies or factories where the monitoring system can be carried out in real time and anywhere using Android. This prototype is made using a 30WP solar panel and uses a buck converter as a voltage reducer that enters from the panel which then the current and voltage will be read by the INA219 sensor which is then processed by Arduino so that it can be displayed by Blynk on Android which is of course connected to each other by the internet. This design is also designed when there is an overvoltage there will be a danger alarm notification via a buzzer that sounds. This test is carried out when in charge and discharge conditions which will later be displayed on the blynk when the battery voltage is low or the battery is full so that the charge and discharge process can be carried out by pressing the on or off button on the blynk so that the load will be in two conditions, namely on and off. The battery is in low condition if the voltage is less than 12.3 volts then there will be a notification tone on the blynk, while the battery is in full condition, namely at a voltage of 13.5 volts it will also display a notification which can be displayed by the blynk.

Abstract

Using solar energy as a source of electricity has great potential. A boost converter is needed to overcome the low energy conversion efficiency of solar panels. Many boost converters have been used to achieve high efficiency, one of which is the quadratic boost converter. This study aims to increase the efficiency of solar panel output at low inputs. An overall study of the system with a lamp load of 2 volts from 09.00 WIB to 15.00 WIB showed that the highest efficiency was achieved at 10.15 am at 99% with an average efficiency of 80%. At the same time, the output voltage is 24.64 volts. From the voltage and current obtained simultaneously, the input power is 2.99 watts and the output power is 2.97 watts. From the tests I did, it appears that the quadratic boost converter can provide a fairly high output voltage. Low-duty cycles have been shown to produce higher output voltages than traditional boost converters.

Abstract

Ten percent of fishermen in Muncar District, Banyuwangi, use floating rafts as their fishing equipment, equipped with generators as their source of electricity for lighting. However, the use of generators is considered less effective because they rely on scarce fuel oil, the price of which increases every year. To address these issues, this community service project aims to develop micro-hydro power plants and harness seawater chemical energy as an alternative to fuel-powered generators. The project commenced with observations and outreach to fishermen and village officials. Subsequently, the project progressed to designing a tool and applying it to one of the floating rafts as a feasibility test sample. The project concluded with the delivery of these tools to the fishermen after they were confirmed to be functioning properly. The electricity generated from a set of 20 voltaic cells reaches a maximum value of 9.15 V and still requires a DC-DC converter to power the 12 V LED lamp. This tool still necessitates additional power to ensure the electricity generated can meet the lamp's power requirements.

Abstract

This low soybean production is caused by various factors, including farming technology that is still not good, the readiness and skills of soybean farmers are still lacking, The current conventional/traditional system used by farmers to grow soybeans is to make holes with a small hole or wood. After that put 2-3 soybean seeds in each hole and then cover it with soil, this kind of activity takes a long time, causing discomfort for farmers or farm workers. The target of this activity is farmers by encouraging them planting soybeans in Panduman Village which is still possible from a geographical point of view and directing profit-oriented farming in an effective planting time process. In the planting activity, the design prototype planted soybeans in 2 planting rows with a working capacity of ≤ 18 hours/ha with a seed output of 2-3 seeds/planting hole and a planting depth of 3-5 cm and regular spacing of 40 cm and the seeds were covered with soil cover. The design of the development of this planting machine is considered quite good in planting soybeans.
