Abstract

A structure due to natural disasters often occurs in Indonesia, and this is caused by the location of Indonesia in the path of earthquakes and volcanoes. Logistics delivery in the form of medicines and food has been hampered, and this is acknowledged by the Indonesian government, which experienced many obstacles when it had to reach an isolated location due to land transportation lines being cut off. So it was designed an Unmanned Aerial Vehicle (UAV) or drone that can deliver survival kits to some places that are isolated due to natural disasters autonomously. Flight orders will be made through the Mission Planner software, which is then sent to the drone using 433 MHz telemetries. Survival kits carried by drones will be dropped using a servo to a predetermined location. The work of Vertical Take-Off Landing (VTOL) for Drop Kits has successfully carried out a mission to deliver survival kits to 4 different locations in one flight. By using the 433 MHz Telemetry, the drone can travel a maximum distance of 120 meters in 5 minutes 10 seconds with a 9 Ah battery capacity.

Abstract

Pests are one of the main enemies of rice farmers who at any time can attack crops. The impact of rice pest attacks can reduce the production of rice crops, causing crop yields to decline. One of the pests that often unsettling rice farmers is bird pests (Passer spp.) and rats (Hundred argentiventer), the pest attack is determined by the state of the climate, and the unwise use of insecticides and the manual expulsion of pests takes a lot of time.  To reduce the above problems in this study will develop new innovations in agriculture, through The Repellent Tool Automatically is one way to help rice farmers to pollute the environment and expulsion manually. In this tool is installed a micro controller raspberry pi 3 as a link between the pear sensor and the camera module, in addition raspberry pi 3 is integrated with the smartphone application in real-time for the process of monitoring the presence of pests and using speakers to repel pests. The test results obtained by rat pests are disturbed when the speakers emit an ultrasonic wave frequency of 34-45KHz and bird pests will be disturbed if the speakers emit a frequency of 60kHz. The PIR sensor can detect the presence of rat pests with a vulnerable distance of 5-50cm, while the camera detects the movement of bird groups and gets an accuracy percentage of 44.4% of the test results and an average delay of 1.08 seconds.

Abstract

The need for water in each land varies depending on the area and conditions of the land. In addition, the technology is still done manually. We need a lot of time to irrigate the plants therefore it is not effective. Efforts must be made to optimize water management, such as on-time, on quantity, and on target, as well as covering a large area. This research proposes an android-based automatic floodgate telecontrolling system by utilizing a Soil Moisture sensor and an android application. Relays are used as opening and closing sluices. The results of the relay status when on or off and the humidity value will enter the application and can be monitored in real-time. The test results show that the Soil Moisture  Sensor can detect Soil Moisture with an average error of 0.362%. The control and monitoring system through the application using Android is in accordance with the plan with an average delay for ON / OFF status and a humidity value of 0.487295s.

Abstract

The increase in temperature on optical fiber results in an increase in the refractive index and Numerical Aperture, resulting in spread and absorption losses in the optical fiber. So it is considered necessary to discuss the effect of temperature changes on wave length in axially connected Singlemode-Multimode fiber optic media. Optical fiber connected to OSA is heated using a heater to show the wavelength value, before converted into color. Then convert it into CCT so as to produce a temperature value in kelvins. In this study, singlemode, multimode, singlemode-multimode fiber are used. The connection to each optical fiber and light source uses a Fusion Splicer and Visual Fault Locator with a wavelength of 660 nm and 680 nm, respectively. Results show that the higher the temperature, the farther the wavelength shift. The singlemode-multimode cable has the farthest shift value of 8.44 nm at 660 nm and 9.3 nm at 680 nm. Singlemode-multimode cable has the best measurement accuracy value. Because at a wavelength of 660 nm, the difference between the temperature values ??measured on the thermocouple and those calculated on the matlab has an average percentage of 0.54%. Meanwhile, at a wavelength of 680 nm it is 0.63%.

Abstract

Dalam sistem komunikasi seluler di Indonesia yang masih berada di teknologi HSDPA dan HSUPA, maka parameter pengukuran kualitas sinyal yang diterima oleh user seperti RSCP (Received Signal Code Power) dibutuhkan guna mengetahui kualitas jaringan yang telah dibangun. Untuk mengetahui nilai dari parameter RSCP maka dilakukan pengukuran  dan  perhitungan.  Pada  pengukuran dapat menggunakan  drive  test.  Dan  pada perhitungan  dapat  dilakukan  dengan  menghitung terlebih  dahulu  nilai  path  loss setiap  nodeB.  Dengan menggunakan 2 model perhitungan path loss yaitu Walfisch Ikegami dan Cost 231 Hata. Kemudian dilanjutkan dengan perhitungan EIRP dan perhitungan RSCP. Sehingga hasil dari pengukuran parameter RSCP menggunakan drive test dapat dibandingkan dengan hasil perhitungan parameter RSCP. Adanya analisis parameter RSCP berguna untuk mengetahui dampak dari jarak jangkauan sebuah nodeB dan path loss dari nodeB tersebut sehingga sinyal dapat diterima oleh user dengan baik. Dari 13 nodeB tersebut diperoleh nilai parameter RSCP pada perhitungan RSCP menunjukkan semakin jauh jangkauan cell maka nilai path loss akan semakin tinggi dan nilai RSCP yang dihasilkan akan semakin rendah, sehingga area layanan yang jaraknya jauh dari nodeB tidak terlayani dengan baik. Nilai parameter RSCP dengan perhitungan menggunakan path loss Walfisch Ikegami menunjukkan nilai yang lebih rendah dibandingkan menggunakan path loss Cost 231 Hata. Dan hasil Pengukuran parameter RSCP menggunakan drive test menunjukkan nilai yang mendekati dengan perhitungan menggunakan path loss Cost 231 Hata.

Abstract

Keripik merupakan sejenis makanan ringan berupa irisan tipis dari umbi-umbian, buah-buahan, atau sayuran yang digoreng di dalam minyak nabati. Untuk menghasilkan rasa yang gurih dan renyah biasanya dicampur dengan adonan tepung yang diberi bumbu rempah tertentu. Keripik merupakah satu jenis makanan yang banyak di sukai oleh masyrakat adalah keripik tempe, keripik singkong, keripik buah dll. Di kota Madiun khususnya kecamatan kebonsari banyak sekali produsen keripik diantaranya keripik tempe dan aneka keripik lainnya sebagai mata pencaharian lain selain bertani salah satunya adalah Mashudi yang berlamatkan di Baleboto, Pucanganom, Kecamatan Kebonsari. Dalam menjalankan usahanya bapak mashudi dibantu istrinya untuk memproduksi keripik tempe. Dalam memproduksi keripik belum mempunyai merek dagang dan belum memenuhi permintaan dikarenakan terbatasnya produktivitas akibat penggunaan alat irisan tangan dan sulit mengembangkan pasar. Metode yang digunakan adalah memberikan alat dan pelatihan cara pengoperasian alat pengiris keripik dan pengemas makanan meningkatkan produktifitas dan kualitas produksi keripik. Mesin pengiris aneka keripik yang dihibahkan telah memudahkan produsen keripik tempe untuk mengiris tempe serta mengiris aneka bahan keripik lainnya diantaranya singkong, sukun, ketela sehingga produktivitas dan jenis produksi keripik meningkat, peningkatan kualitas kemasan dengan menggunakan handsealer sehingga keripik lebih tahan lama dan terjaga tingkat kerenyahannya, desain label merek dagang dan kemasan telah dilakukan agar produk yang dihasilkan siap dipasarkan.
