Currently the development of robots has reached a high level of complexity. However, it is also accompanied by increasing complexity problems in its control. Some control with the image processing method also requires competent operators, at least memorize each command used. Therefore, to reduce the complexity in its control, in this research robot control, especially humanoid robot is made using motion capture method. Motion capture is a control technique using a camera transducer in the form of Microsoft Kinect, to obtain the coordinate skeleton of the joint user. Furthermore the data is processed in Visual Studio software to obtain the angular information that will be formed by the robot. So that the robot can perform the same movement with the user. The information is transmitted wirelessly to the microcontroller contained on the robot in real-time. The results of research showed that the system can translate the user's movement into information movement of humanoid robot. With an average skeleton vector detection error of 1.69 cm, an average response time of 1.3 seconds and an absolute error average position of the end effector on the x axis of 3.2 cm and on the y-axis of 1.28 cm.

Charger is an important part in e-car. For a massive number of e-cars in the future, battery charger should have characteristics of high efficiency, rapid charging capability, portability, low-cost and compatible with the national standar electricity. In order to cover thus five parameters, the battery charger design should be transformerless, employing buck swith converting method, and having a microprocessor to monitor and control charging voltage and current during charging process. In this paper, we do simulation and experiment with a battery charger prototype, where the input is 220V-50Hz (PLN) and transformerless. To control the charging voltage and current output of buck switch converter, we use a microprocessor circuit. The charging voltage and current of the battery charger are 36-96V DC and 0 s/d 20 A, respectively.

Public-Private Partnerships (PPPs) have emerged along with the growing role of corporations in global development. One of the largest forms of PPP today is the UN Global Compact. The UN Global Compact involves of companies, NGOs, IGOs and state governments. All of them are trying to realize globalization with a more humanist face with attention to the protection of human rights, environment, labor standards and anticorruption. Engaging private actors in global governance, The UN Global Compact raises many issues such as power, authority, and legitimacy. The effort to tackle it all is to increase PPP accountability. This research seeks to describe what efforts can be made to enhance private accountability within the international regime. The research undertaken is a descriptive study, focuses on public-private partnerships in the UN Global Compact regime. The study found that there were two attempts that could be done. First, by involving the stakeholders in the development of procedures, mechanisms, reporting and monitoring associated with trying to improve the company's reputation. Second, by looking at corporate relations as agent and UN Global Compact as principal in principal-agent relation in the international regime. Keywords

Penanaman tanaman stroberi secara konvensional cukup sulit dilakukan karena membutuhkan ruang, tenaga kerja, air, serta lahan yang subur. Karenanya, penanaman tanaman tanpa tanah dapat diterapkan. Sistem aeroponik adalah penanaman menggunakan media udara. Akar tanaman dibiarkan menggantung dan disemprot nutrisi. Keistimewaannya adalah dapat mengurangi konsumsi air, pupuk, dan pemaksimalan lahan. Pada penelitian ini mist nozzle dikendalikan oleh mikrokomputer menggunakan  logika Fuzzy untuk menyemprot bagian akar dan tajuk dengan masukan sensor suhu dan kelembapan. Kebutuhan nutrisi akar dikendalikan dengan metode on-off. LED dikendalikan menurut waktu. Kadar pH pada tandon nutrisi dapat diawasi menggunakan sensor pH. Sistem dapat diawasi dan dikendalikan dengan antarmuka pada Android. Hasil penelitian menunjukkan ketercapaian nilai rata-rata kebutuhan suhu akar yakni 23,3℃ dari rentang 18-30℃, dan suhu tajuk 21,5℃ dari rentang 14-25℃. Selain itu, kelembapan akar dan tajuk juga masuk dalam rentang kebutuhan 85-95% yakni 89% dan 93%.  Sistem pengawasan dan pengendalian dapat dilakukan dari jarak jauh dengan menggunakan aplikasi Blynk.
