Pemanfaatan perangkat mobile dengan sistem operasi android yang digunakan sebagai media pendukung serta suplemen dalam meningkatkan hasil belajar dipadukan dengan metode demontrasi dan discovery learning atau demon-disco learning sangat diperlukan untuk membantu siswa dalam meningkatan hasil belajar pada mata pelajaran kompetensi kejuruan Budidaya tanaman secara hidroponik di SMK Kristen Terang Bangsa, karena penggunaan aplikasi berbasis android dapat memberikan pengalaman baru mengenai pemanfaatan teknologi informasi dan komunikasi, serta memberikan kesempatan kepada siswa untuk dapat belajar secara lebih mandiri.
Konsep yang dipilih sebagai media pembelajaran yaitu memaparkan materi tentang pengertian, pengenalan bagian-bagian, jenis –jenis,  serta quiz berisi soal tentang budidaya tanaman secara hidroponik. Penelitian ini menggunakan metode pengembangan produk Research and Development (RnD), dengan memakai 6 dari 10 tahap penelitian yaitu potensi dan masalah, pengumpulan data, desain produk, validasi desain, perbaikan desain, uji Coba produk.
Hasil dari penelitian ini adalah menghasilkan media pembelajaran  berupa aplikasi berbasis android. Adapun nilai validitas dari ahli media sebesar 2,6 dimana dinyatakan layak, sedangkan nilai validitas dari ahli materi sebesar 3,6 dimana dinyatakan layak, dan mampu meningkatkan nilai rata-rata pada mata pelajaran kompetensi kejuruan budidaya tanaman secara hidroponik di SMK Kristen Terang Bangsa yang semula 67 (dengan 13 siswa yang belum mencapai KKM) menjadi 80 (dengan 4 siswa yang belum mencapai KKM).

Assessment of employee performance is expected to know precisely the success in completing work. Employee performance appraisal is also useful for companies in providing feedback to employees and can be used as a basis for agencies to evaluate employee performance. Most government services currently utilize information technology as an information service to the public and the agency's internal services. In institutions, it is necessary to increase and develop the capabilities, knowledge and skills of its human resources, so that it is expected to be able to produce apparatuses that have competitive competencies. Therefore, the authors designed and built an employee performance appraisal system which was implemented using Electre and Web-based and Android methods. It is expected to be able to assist agencies in evaluating employee performance so that they can remain consistent in carrying out their duties as Civil Servants (PNS) within the scope of services to the community. This research uses the R&D method. researchers only use up to step 6. Based on the results of trials of 10 respondents who have assessed the decision making system using the electre method, that the application of employee performance appraisal using aggregate ranking can help provide information on the level of employee performance based on predetermined criteria. Respondents agree that this system is more efficient in assessing employee performance with an average of the old system = 43.50% while the new system is = 84.50%.

This study generally aims to design an information system that can handle problems in putting and sorting goods into warehouses at CV. Sekar Intan KIC Gatsu, Semarang. In terms of using the Information System, CV. Sekar Intan KIC Gatsu, Semarang. In the transfer and sort of goods in the warehouse still using a manual system when the implementation, warehouse employees must take and place the goods to the warehouse that has been determined each - each type of item, so employees must calculate the number of items when the goods take place, here various problems occur, because it requires some HR to manage the warehouse performance process at CV. Sekar Intan.
To support the research, researchers used Research and Development (R & D) research methods through the microcontroller-based moving robot design simulation design stages that have been tested by experts declared valid with Valid validity levels and final product development design simulation prototypes carried out. goods transfer robot uses Arduino IDE development software that is integrated with Arduino Mega 2560, 6 pin line sensor, dc motor, motor driver, servo motor, motor driver, lcd, and has been tested in the field by General Adv. Administration and HRD as users / users and stated to be very effective.
Based on the results of the research and discussion, it can be concluded that the robot design system developed can overcome the problems in the old system on the CV. Sekar Intan KIC Gatsu Semarang, so as to produce a system that can facilitate work processes and parking processes for employees to be more effective and efficient.
