Judul: Aplikasi bahasa mesin pada perangkat mikroprosesor Z-80 untuk kontrol digital cara proporsional pada mdel pengeringan benih jagung (Zea mays L.)
Abstrak: Mikroprosesor merupakan suatu komponen rangkaian elektronik yang telah menimbulkan perubahan besar dalam cara perancangan sistem elektronik. Dalam penerapannya yang beraneka ragam, mikroprosesor telah digunakan dalam kalkulator saku, instrumen laboratorium, barang komsumer, sistem pengendalian pesawat terbang dan sistem-sistem komputer. Salah satu aplikasi dari pengontrolan suhu ini adalah pada ruang pengering benih jagung. Benih jagung berupa butiran biji jagung yang diperoleh dari tanaman yang telah tua. Untuk menjaga tingkat germinitas benih, maka perlu dilakukan pengontrolan suhu dan kelembaban pada ruang pengeringnya. Suhu yang terlalu rendah dan kelembaban tinggi akan menyebabkan benih tumbuh sebelum waktunya. Sedangkan suhu yang terlalu tinggi akan menyebabkan benih menjadi rusak dan tidak dapat ditanam. Dengan kontrol otomatik maka kondisi suhu dapat terjaga dalam kisaran suhu yang aman dan optimal bagi benih jagung.

Judul: Pembuatan Alat Tanam Benih Jagung (zea mays) Otomatis Berbasis  Mikrokontroler
Abstrak: Until this time, majority of Indonesian farmers plant seeds by using a dibble (conventional method), that needs extra power, more human operators and is ergonomically inefficient. Therefore, a more precision seedling machine is needed to alter the manually seedling process into mechanically seedling process by using seed planter. A seed planter consists of mechanical component and electronic components. The mechanical component includes draft machine, dibble wheels, a supporting wheel, hopper, a metering device , a drainage tube, a fertilizer plot opener, and a covering hole device. The electronic component includes a metering motor, a micro-controller, a magnet sensors, a motor-driver and a electrical power supply. The design methodology used in this research is based on functional and structural design. Moreover, ergonomic values of the designed seed planter are also condidered based on the Indonesian average anthropometries. This dimension of the seed planter is of 130 cm (length) x 100 cm (width) x 90 cm (height) cm. The length of the connecting rod is 110 cm with a wheel diameter of drill 40 cm. The seed storage capacity of the hopper is 3.0 kg. The metering device diameter is 12 cm. The operating capacity of the croping tool is 11.63 hours / ha. The proposed seed planter is designed to be operated by a single human operator with pushing power of 223.71 watts. The enriched feature of the seed planter is precicesness of seeding and and multifunction capabilities (making seed holes, allocating seed & granular pesticide, closing seed holes, producing fertilizing rows).

Judul: Profil Gambaran Eritrosit Lumba-lumba Hidung Botol Indo-Pasifik (Tursiops aduncus) di Pusat Konservasi Mamalia Air PT. Wersut Seguni Indonesia.
Abstrak: Bottlenose dolphin (Tursiops aduncus) is one of worldwide marine mammals. The status of this dolphin is poorly known and thus many research are needed to understand more about bottlenose dolphin, both free range and captive. The aim of this research was to analyze erythrocyte profile of bottlenose dolphins who live in captive (PT Wersut Seguni Indonesia). Erythrocyte parameters analyzed were total erythrocyte, packed cell volume (PCV), haemoglobin, and erythrocyte indices. This research used 7 dolphins (Tursiops aduncus) on September 2013 at PT. Wersut Seguni Indonesia. The blood was collect from the dorsal part of superficial vein in flukes region. The result shown that those dolphins had 5.14 ± 0.56 × 106 /mm3 of erythrocyte, 13.86 ± 1.68 g/dL haemoglobin concentration, 44.29 ± 2.69 % PCV, 86.57 ± 5.91 fl MCV, 26.94 ± 1.23 pg MCH, and 31.20 ± 2.30 g/dL MCHC. The result shown that erythrocyte profile of Tursiops aduncus is higher than Tursiops truncatus both at free range and captive.
