Abstract

Sistem informasi akademik berbasis mobile merupakan sistem informasi yang menyediakan informasi akademik unrtuk tingkat mahasiswa, yang di rancang khusus untuk perangkat bergerak/Smartphone android. Dengan sistem akademik berbasis mobile, mahasiswa diharapkan dapat memperoleh informasi yang berhubungan dengan kegiatan akademik yang sedang di tempuh, baik bisa di lihat secara offline maupun online, untuk memberikan kemudahan dalam memperoleh informasi akademik. Rancangan interface pada penelitian ini menggunakan software eclipse dan penyimpanan basis data menggunakan MSQL. Metode yang digunakan adalah metode waterfall. Hasil dari perancangan ini adalah sebuah sistem informasi akademik berbasis Mobile yang berguna untuk memudahkan mahasiswa dalam mendapatkan informasi akademik melalui perangkat yang bergerak/smartphone. dari hasil pengujian black box didapatkan hasil bahwa aplikasi ini sudah dapat memberikan informasi sesuai dengan kebutuhan mahasiswa. Kata kunci: Sistem Informasi Akademik, mobile, MySql, Eclipse Mobile-based academic information system is an information system that provides academic information for students, designed especially for mobile devices/android smartphones. With a mobile-based academic system, students are expected to obtain information related to academic activities, both can be viewed offline and online, in order to provide ease in accessing academic information. Interface design in this paper is using eclipse software and the database storage is using MSQL, while the method used is waterfall method. The result of this design is a mobilebased academic information system that is useful to facilitate students in obtaining academic information through mobile devices / smartphones. The testing of black box shows that this application has been able to provide information that is suitable with students need. Keywords: Academic information system, mobile, MySql, Eclipse

Abstract

The antenna is the most important part in a wireless communication system. Microstrip one type of antenna that has practical size and dimensions that are simple and easy to fabricate. In this research, we designed and analyzed two slit single layer microstrip antennas for Zigbee technology applications that operate in the 2.4 GHz band. Today, this application has become important for everyday use in industry and home automation, in small areas due to low power requirements for operation and long battery life. The antenna is built on FR-4 epoxy substrate with a thickness of 1.6 mm and εr = 4.4. Antennas operating at 2.4 GHz Resonance frequency have a VSWR value of 1.8 and a Returnloss value of -11 dB with a Vertical radiation pattern, resulting in a narrow impedance bandwidth that can protect the Antenna against interference from other applications in the ISM band. The antenna produced has a patch size of 5.2 cm × 5.2 cm2 with a slit distance of 1 mm. Antennas have advantages in simple design, narrow bandwidth, and their compact size and ease of publication, the test results of the parameters-Parameters, the antenna has met the qualifications of a good antenna standard for zigbee technology.

Abstract

The facilities used by Posyandu cadres in weighing and measuring the height of children under five are not sufficient, because apart from that, they are not feasible nor are they calibrated accurately. Especially for measuring the height of toddlers, so far the posyandu generally still use the manual method, Based on this background, a digital height measuring device was designed in order to refer to the mission of the Unisma Bekasi Faculty of Engineering in an effort to increase the quantity and quality of community service (PPM) in the field of applied technology (appropriate technology), so this program was implemented. The PPM partners targeted for this program are Posyandu Kemuning cadres, Jatirasa Village, Jatiasih District, Bekasi City. The results of the design of this tool complete the automatic height measurement which is quite satisfactory at the Kemuning Posyandu, Jatirasa Village, Jatiasih District, Bekasi City. Development of a baby height and body mass measurement tool based on the ATmega 8535 microcontroller by utilizing a phototransistor sensor.

Abstract

Material Paduan logam adalah material yang terdiri dari beberapa jenis unsur logam.Metoda pembuatan. Paduan logam dapat dengan cara peleburan atau dengan metalurgi serbuk. Paduan aluminium sangat maju di dunia manufaktur, mengingat karena Paduan dapat meningkatkan kekuatan aluminium. Tujuan penelitian ini menganalisa efek dari variasi komposisi paduan Al-Cu-Mg melalui proses sintering dan annealing terhadap metalografi dan kekerasan menggunakan metode metalurgi serbuk.untuk komposisi utama yaitu aluminium 80%, variasi Cu 8%,5%,2% dan variasi Mg 12%,15%,18%.proses mixing dan dikompaksi dengan tekanan sebesar 7 ton .suhu sintering 480℃ dilakukan selama 1 jam dan diannealing 320℃ dilakukan selama 1 jam yang kemudian didinginkan didalam tungku. Spesimen yang sudah disintering dan diannealing akan dilakukan pengujian Metalografi dan pengujian kekerasan. Dari penelitian ini diharapkan akan didapatkan nilai kekerasan dan foto metalografi sebagai bahan untuk melihat kualitas Paduan AL-CU-Mg.
