Penelitian yang dilakukan pada Universitas Semarang dengan objek mahasiswa atau calon penerima beasiswa. Beasiswa diberikan untuk membantu mahasiswa dalam menempuh studinya. Ada beberapa beasiswa yang diberikan kepada mahasiswa Universitas Semarang diantaranya dari Yayasan maupun dari instansi yang bekerja sama dengan Universitas Semarang. Dalam penelitian ini dibahas mengenai pemberian beasiswa Peningkatan Prestasi Akademik (PPA). Untuk mempermudah dalam pengambilan keputusan dalam penentuan mahasiswa yang layak menerima beasiswa diperlukan sebuah sistem pendukung keputusan yang menguji kriteria-kriteria sebagai salah satu syarat dalam seleksi penerimaan beasiswa. Kriteria ini diuji dengan menggunakan metode Topsis (Technique for Order Preference by Similarity to Ideal Solution). Dengan metode Topsis digunakan untuk mencari alternatif dengan kriteria-kriteria tertentu. Penelitian dilakukan dengan mencari nilai bobot untuk setiap atribut untuk menentukan alternatif yang diberikan. Proses penentuan beasiswa dengan metode Topsis dapat mempercepat proses seleksi penerima beasiswa dan mengurangi kesalahan dalam menentukan mahasiswa yang layak mendapat beasiswa.

Pengawasan tempat/ruangan dalam pekerjaan merupakan hal penting, dimana dengan adanya CCTV pemantau kita bisa melihat kondisi suatu tempat dengan bantuan kamera pemantau (CCTV). Selama ini untuk perekaman CCTV mengunakan DVR (Digital Video Recording) dimana perangkat ini cenderung mahal dan belum menjangkau semua kalangan. Terlebih lagi jika CCTV merekam secara terus menerus 24 jam sehari selama 1 bulan, tentu harus menyediakan kapasitas ruang harddisk yang besar.Ruang Lab FTIK menjadi objek penelitian dimana mengunakan perangkat raspberry pi dengan modul kamera dan sensor motion detection dimana perangkat PC Mini Raspberry Pi hanya akan merekam kondisi ruangan hanya pada saat terdeteksi suatu gerakan pada ruang Lab FTIK. Raspberry pi sendiri adalah sebuah komputer mini, sistem operasi Raspberry bisa bermacam-macam, salah satunya adalah Linux Debian yang telah dipaket minikan. Dengan itu diharapkan mampu mengurangi beban media penyimpanan. Penggunaan Raspberry Pi dalam hal pengawasan/monitoring tempat atau ruangan memerlukan biaya yang murah dan efektif dalam pendayagunaan.
工作场所/房间监控是一件重要的事情，通过CCTV监控，我们可以在监控摄像头（CCTV）的帮助下看到某个地方的情况。一直以来，CCTV录像都使用DVR，而这种设备往往很昂贵，而且还没有覆盖所有对。特别是，如果CCTV连续一个月24小时不间断地录制，它肯定需要提供巨大的硬盘空间。FTIK实验室空间成为一个研究对象，它使用带有摄像头模块和运动检测传感器的π-树莓设备，其中PC Mini raspberry[UNK]pi设备仅在FTIK实验室中检测到运动时记录房间的状态。树莓派本身就是一台迷你电脑，树莓操作系统可以多种多样，其中之一就是已经迷你打包的Debian Linux。这有望减少存储介质的负担。使用Raspberry Pi进行现场或空间监视/监控需要廉价高效的使用成本。

The growth of microorganisms in foodstuffs can lead to profitable changes such as nutritional improvements in food, digestibility or storage. In addition, the growth of microorganisms in food can also lead to undesirable physical and chemical changes, so the food is not worth consuming. Staphylococcus aureus and Escherichia coli are the bacteria that often cause infection in humans. To prevent this it is necessary to have bioactive components that can inhibit the growth of microorganisms. Active compounds such as saponins, triterpenoids, phenols, tannins, flavonoids and alkaloids are known to have antibacterial activity. Several studies have reported the chemical content found in corn hair. Corn hair is part of a corn plant that has not been used effectively because it is considered as waste. Based on research, corn hair contains proteins, vitamins, carbohydrates, calcium salts, potassium, magnesium, and sodium, essential oils, steroids such as sitosterol and stigmasterol, alkaloids, saponins, tannins, and flavonoids. So presumably corn hair extract has antibacterial activity.This study aims to determine the effect of extraction time and concentration of corn hair extract on pH, total phenol and antibacterial activity.The experimental design used in this study was Randomized Block Design (RBD) with 3 replications. The treatments used were Extraction Time A1 = 30 minutes, A2 = 40 minutes, A3 = 50 minutes and Concentration Extract (material: solvent) K1 = 75% (w / v), K2 = 50% (w / v), K3 = 25% (w / v). Furthermore, the data obtained were analyzed variant and if there was any difference between treatments followed by Duncan Multiple Range Test (DMRT) test at 5% level. The results showed that all treatments produced bioactive compounds and formed inhibit zone of each test bacteria. The best time to obtain an antibacterial antibacterial extract on corn hair is 50 minutes. This was supported by the lowest pH average of 5.1 and the highest mean total phenol obtained from treatment A3 (50 minutes) was 7288,64 μgGAE / g and at 75% concentration formed the largest bacterial inhibition zone in each test bacteria.

Sosis daging ayam adalah bahan pangan yang berasal dari potongan kecil daging ayam yang digiling dan diberi bumbu. Bahan sosis yang digunakan adalah daging ayam, karena daging merupakan white meat jadi terlihat pucat jika diolah menjadi sosis berbeda dengan sosis daging sapi, oleh karena itu dilakukan penambahan pewarna alami yang aman dikonsumsi yaitu angkak. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan pengaruh konsentrasi angkak sebagai pewarna alami terhadap sifat fisik dan orlab sosis daging ayam.Metode yang digunakan dalam penelitian ini adalah metode experimental laboratories. Faktor perlakuan yang diterapkan adalah tanpa penambahan angkak (0 %) dan penambahan angkak 1,5 %. Variabel yang diamati yaitu sifat fisik (kadar air, cooking loss), kekenyalan dan orlab. Data yang diperoleh dianalisis menggunakan t test. Hasil penelitian yang telah dilakukan menunjukkan bahwa perlakuan penambahan angkak dengan konsentrasi yang berbeda dalam pembuatan sosis daging ayam afkir (sebagai pewarna alami) berpengaruh nyata (p<0,05) terhadap rata-rata cooking loss tetapi tidak berbeda pada rata-rata kadar air dan kekenyalan. Penambahan angkak dengan konsentrasi 1,5% pada pengolahan sosis daging ayam (sebagai pewarna alami) menghasilkan karakteristik mutu sosis daging ayam yang lebih baik dengan syarat mutu sosis daging ayam dibandingkan tanpa penambahan angkak.

Planting crops in the home environment can provide many benefits, including ensuring the availability of oxygen in the family, as a natural cooling of the house, and as a storage groundwater if the plants get watering and routine maintenance, the benefits derived from plants will be perceived by the family. Using clean water to water the plants every day is a wasteful behavior of water, because water is used for everyday purposes. In addition, the dense activities result in the existing plants at home tend to be lazy to water the plants. Well-groomed plants can provide adequate oxygen for the family.Many ways can be done to solve problems, using soil moisture sensors and temperature sensors to monitor the state of the plant at home, to determine the time of watering using decision support system with the method of SAW (Simple Additive Weighting) to determine the time of watering based on the results of the sensor readings on plants. The existence of this system can be saving water used for watering plants, and plants in the house fulfilled water needs, the benefits of plants can be felt.
