Higher education has several elements of human resources; one of these elements is at the implementing level, namely the security unit or security guard. In self-reliant activities in work environment, this element functions as industrial security or security in the university environment. It is necessary to have a performance evaluation for the security unit that is useful to measure the success of certain targets of an agency; evaluation includes the self-value of each security unit including the variables of knowledge, skills, behavior, work results, and care to you. The method used for performance evaluation the security unit is Simple Additive Weighting. Based on the results of the test it was found that the alternative a7 occupies the highest rank with a value of 80.33 with details of the value of 4 as many as 6 aspects (c3, c10, c16, c19, c24), value 3 as many as 15 aspects (c2, c4, c5, c7, c8, c9 , c11, c12, c14, c15, c17, c18, c20, c23) and the value of 2 in 3 aspects (c1, c6, c13) exceeds alternative a20 with a number of values 4 more than a7, this is influenced by the weight of each aspect.

Sistem pendukung keputusan suatu sistem guna mempermudah dalam penyelesaian masalah juga sebagai pengambilan suatu keputusan. Metode MOORA (Multi-Objective Optimization by Ratio Analysis) adalah sistem pendukung keputusan dimana metode ini memperhitungkan kalkulasi yang kompleks dan dalam penentuan alternatifpun sangat selektif. Dalam penerimaan asisten laboratorium menjadi masalah yang serius karena banyak factor yang harus dipertimbangkan dan diputuskan. Asisten laboratorium bertugas membantu kepala laboratorium dan dosen pengampu dalam proses pelaksanaan praktikum, menjaga dan merawat peralatan serta menjaga kebersihan laboratorium. Selama ini penerimaan asisten laboratorium dilakukan dengan wawancara dan ujian tertulis kemudian baru dilakukan seleksi secara manual. Pada penelitian ini kami mengambil contoh kasus yang sering dialami oleh Prodi Teknik Sipil. Dari rangkaian proses metode MOORA yang digunakan sebagai sistem pendukung keputusan dalam penerimaan asisten laboratorium disimpulkan bahwa metode ini sangat cocok diimplementasikan karena hasil keluaran sesuai dengan target yang diharapkan. Dan nantinya bisa diterapkan di semua fakultas di Lingkungan Universitas PGRI Semarang sebagai sistem dalam sebuah seleksi.

Maka perlu ditemukan cara memecahkan masalah yang ada dengan menyediakan sebuah aplikasi berbasis android yang dapat diakses oleh masyarakat. Metode yang digunakan untuk membangun sistem ini menggunakan metode waterfall dan divisualisasikan dengan use case diagram. Hasil dari penelitian ini adalah aplikasi donor darah yang mampu menyediakan data stok darah, jadwal kegiatan donor dan lokasi, serta informasi donor darah.

The performance of teachers in educational institutions needs to have an appreciation and assessment that has a basis. Teacher performance assessment is one of the bases for decision making related to the career of the teacher. To improve the quality and accuracy of performance appraisal, this study designs a web-based teacher performance assessment decision support system. The Decision Support System method used is Analytical Hierarchy Process (AHP), and information system design uses the Object Oriented Analysis and Design (OOAD) method. Respondents in this study were deputy principals, teacher representatives, and committee representatives. The results of the calculation of the respondent questionnaire were carried out with a paired comparison matrix. The results of the combined calculation showed that the first level criteria which were the highest weighted were Social with a weight of 33.4% and the alternative teacher with the best performance was Vera Asmara with a value of 22.9%.  

Prayer is one of the worship that must be done by all Muslims in this world. If you have entered prayer time, whether we are wherever we are as a devout Muslim it is obligatory to immediately do the prayer. No exception when we are visiting or traveling in a certain area. Therefore, it will be very helpful if there is an application that can find the location of the nearest mosque that can be accessed using a smartphone. Previously, there were similar applications but only accessible via the web. Then, using google maps actually can already find the closest mosque, but there are still shortcomings, namely location data displayed at some point is invalid (the location at certain points there is no mosque). So, the Sigoca Master application (Nearest Mosque Search Information System) in Semarang City based on Android is made to help all Muslims who are visiting or traveling in the City of Semarang. Geolocation and Haversine Formula are the methods I will use to build the Sigoca Master application. With these methods, it is expected that the application built can help find the location of the nearest mosque from the user's location.

Computers now have very high capabilities so they can be used virtualization. With computer capabilities that are high enough computer lab practicum and server administration can already be done on a pc or laptop that has virtualization applications installed. Network practicum and server administration that previously could only be done in the classroom, so with this technology it is expected that it can be practiced on a PC or personal laptop for each student, so that students are able to continue the practical scenario that has been given. Virtualization will use Hyper-V that already exists in Windows 7, Windows 8 and Windows 10. In the Hyper-V application 4 Windows servers will be installed, all of which will be installed and connected via Active Directory. All windows servers will be accessed using a computer and physical network through the Remote Desktop Connection application. So it is expected that with this study student will be able to practice outside the campus lab environment.

Obsessive Compulsive Disorder (OCD) adalah salah satu jenis gangguan psikologi yang berasal dari rasa cemas dan takut yang muncul secara tiba-tiba dan tidak dapat dikendalikan oleh penderitanya. Jika gangguan ini dibiarkan maka akan mengganggu aktivitas sehari-hari penderita dan menyebabkan depresi.
