Briquette is one of the alternative biomass fuels as a substitute for fossil energy. To produce high-quality briquettes is requires printing equipment effectively and efficiently. Therefore, this study aims to obtain the best treatment to make briquettes from coconut shells. Briquetting is made by using 4 pumping variations, namely 4, 6, 8, and 12 times. The parameters observed were hardness, percentage of destruction, moisture content, and the flame of briquettes. The results showed that the best coconut shell briquettes were found in pumping treatment 12 times with an average hardness of 27.7 kg / cm2, percentage of destruction 18.50%, moisture content of 4.55% and the flame of 112.61 minutes. While the worst quality was obtained at pumping 4 times with an average hardness of 16.5 kg / cm2, the percentage of destruction was 43.36%, moisture content was 7.92%, and flame 111.34 minutes.

Untuk melihat ketersediaan air irigasi di suatu daerah digunakan analisa neraca air. Neraca air adalah gambaran potensi penyediaan air dan potensi kebutuhan air. Tujuan dari penelitian ini adalah menghitung debit masukan dan keluaran dari air irigasi Pijenan Bantul yang akan disesuaikan dengan pola tata tanam di daerah tersebut. Metodologi dalam penelitian ini adalah eksperimental dengan pengambilan data di daerah irigasi Pijenan Bantul. Alat dan bahan yang digunakan adalah current meter, pita ukur, blangko kebutuhan air irigasi. Hasil penelitian menunjukkan debit selama 10 tahun (2003-2013) sebesar 683,730 hingga 10.237,338 l/dt dan debit kebutuhan rata-rata 1823 l/dt. Hubungan antara debit ketersediaan dan debit kebutuhan di pintu tersier dapat ditunjukkan dari analisis neraca air dimana pada daerah hulu kebutuhan irigasi selalu lebih kecil dari debit yang tersedia, di daerah tengah debit kebutuhan seimbang dengan debit ketersediaan, sedangkan di daerah hilir debit kebutuhan lebih besar daripada debit ketersediaan. Hasil perhitungan faktor K didapatkan lebih kecil dari 0,7 yang artinya terjadi defisit air sehingga perlu system irigasi giliran.To see the availability of irrigation water in an area water balance analysisis used. Water balance is a description of potential water supply and potential water requirement. The purpose of this research was to calculate the input and output irrigation waterdischarge from PijenanBantul that will be adjusted with the pattern of planting system in the area.The methodology in this research was experimental with data retrieval in PijenanBantul irrigation area. Tools and materials used were current meters, measuring tape, form of irrigationwater requirement. The results showed that thedischarge for 10 years (2003-2013) was 683.730 to 10,237.338 l/dt and the average requirement was 1823 l/dt. The relationship between the availability and the requireddischarge of the tertiary gate could be shown from the water balance analysis where upstream irrigation water requirements were always smaller than the available discharge; in the middle area the required discharge was equal with the available discharge; whereas in the downstream area, the requireddischarge was greater than the available discharge. The calculation result of K factor was smaller than 0,7 which means water deficit was existed, therefore the rotation irrigation system was necessary.

Control of temperature and humidity of air in plant houses which is microclimate control is necessary to do for optimal plant growth. The purpose of this research is to design and test the performance of microclimate control and monitoring systems in plant houses. Research tools and materials include plant houses, Arduino microcontrollers, DHT22 sensors, RTC DS3231, TFT LCD 128×64 12864, DC Pumps, 0.2 mm nozzles, relays, SD card modules, and exhaust fans. The method used is an experimental method of using a water misting system to control the temperature and humidity of the air. From the results obtained, the microclimate control design can work automatically assisted by DHT22 sensors. When the air temperature reaches > 29°C, the active air wasting fan releases hot air. Whereas when air humidity drops to <80%, active air humidifiers increase air humidity.

Seiring dengan perkembangan teknologi dan ilmu pengetahuan, akhir - akhir ini bidang elektronika mengalami kemajuan yang pesat. Hampir peralatan elektronik di buat dengan canggih untuk mempermudah pekerjaan manusia. Penelitian ini bertujuan merancang bangun alat alat sistem kendali pengemas kedelai semi otomatis. Metodologi penelitian ini bersifat eksperimental dengan pendekatan desain struktural dan fungsional sistem kendali. Alat yang digunakan antara lain sensor load cell, modul HX711, LCD, arduino UNO sedangkan bahan yang digunakan adalah campuran kedelai dengan ragi tempe. Hasil penelitian ini menunjukkan sistem ini mampu membaca massa benda dengan akurat dengan standar devaiasi 6,4 dan dapat di baca melalui LCD. Sistem pengendalian juga telah bekerja dengan baik sesuai dengan set poin yang telah ditetapkan sebesar 3 kg pintu hopper akan tertutup.

Abstrak: Pengeringan didefinisikan sebagai proses pemindahan air dengan menggunakan panas dan aliran udara untuk mencegah atau menghambat pertumbuhan jamur dan bakteri. Tujuan kegiatan ini adalah meningkatkan pemahaman mahasiswa tentang penerapan teknologi pengeringan, sehingga membantu mahasiswa menentukan minat studi pada awal semester 5. Sebanyak 40 mahasiswa terlibat dalam kegiatan pengabdian ini. Hasil dari kegiatan ini menunjukkan 80% mahasiswa lebih memahami aplikasi proses pengeringan secara keseluruhan, dari awal hingga akhir proses.Abstract: Drying is a process to remove water using heat and air flow, in order to prevent or inhibit the growth of fungi and bacteria. The purpose of this activity was to increase student’s understanding of drying technology application, that would help the student to determine their study interest in early of the 5th semester. As many as 40 students were involved in this activity. The results of this activity showed approximately 80% students have a better understanding regarding the application of the overall drying process, from the beginning to the final process.
