“Digital Formaldehyde Meter” Inovasi Pendeteksi Kandungan Formalin Cepat Dan Akurat Dengan Teknologi Berbasis Instrumen Electronic Nose

Design of measuring device formalin with "Digital Formaldehyde Meter" that implementation of the Electronic Nose is an alternative technology to produce quick and accurate detector. "Digital Formaldehyde Meter" is designed with a digital system, the input signal detected the sensor array TGS (TGS 2600, and 2611), and processed with the help of microcontroller and digitized by a digital LCD (Liquid Crystal Display) to digital convertor. System instrumentation is based on "Digital Formaldehyde Meter" using solid and liquid samples. Process calibration tool "Digital Formaldehyde Meter" is performed by comparison tool uv spectrometer and the test produced an average error of 2.93%

Lumos (Lighting Automatic Potatos Seeding), Aplikasi Teknologi Pembenihan Kentang Berbasis Photopheriodic

Sumberbrantas is an Agroindustrial village in Malang, East java, with the main commodities are potatoes. One of the farmer groups engaged in potatoes agricultural sector is Anjasmoro farmer groups III. This farmer groups special program is perform independently potato seeding in the greenhouse. But, this process is not optimal because of less lighting so the potatoes seed produced susceptible to disease and has a small size. Therefore, we innovate to apply LUMOS technology. LUMOS is an automatic lighting system based on photoperiodic. The purpose of this program is to determine a method of designing, manufacturing, Lumos application influences and effective way of socialization. Lumos has a size of 25m × 5m. there are 4 18 watt lights, there are control Box size 15cm × 21cm × 5cm, and can be used for 5 years. Making Lumos begins with assembly hardware, sensor calibration and software development. The results showed that potatoes produced has a diameter of 8.128 mm and a mass of 31.3 grams greater than before. This technology is able to produce potatoes seed up to 7,000 seeds/period and profit reached Rp 20,169,000.00 annually. It is expected that this technology into a technology demonstration for other potato farmers in Indonesia
