Air conditioner (AC) is a device that requires high power. To reduce the energy waste by AC, the temperature setting should be adjusted to the room condition. It can be affected by the number of persons and the level of activity in the room. To save electricity consumption, this research is conducted to design an intelligent and automatic AC system based on identification of number of persons and activity level to control working temperature of AC using fuzzy logic refers to thermal comfort standard in Indonesia issued by SNI council. The system used USB camera as an image capture device. In image processing, Histogram of Oriented Gradient (HOG) method is used to identify the number of people, while background subtraction method is used to identify the activity level. This system is implemented into Raspberry Pi 3 as a single board computing. Test results show that the system is capable to detect people from a distance of 3m to 9m and distinguish 2 people within a distance of 30 cm to 150 cm, The system can also differentiate small, medium and high of activity levels. The test results show that the working temperature controlled by the designed fuzzy logic has the lowest value of 21°C and the highest value of 27°C which is in accordance with the thermal comfort standard that has been defined by the SNI council. The differences between working temperature and measured room temperature are within only 0.2°C to 1.2°C.
空调是一种功率要求较高的设备。为减少空调对能源的浪费，空调的温度设置应根据房间的实际情况进行调整。它可能受到人数和房间内活动程度的影响。为了节约电力消耗，本研究参照SNI理事会在印度尼西亚颁布的热舒适标准，设计一种基于人数识别和活动水平识别的智能自动空调系统，利用模糊逻辑控制空调的工作温度。系统采用USB摄像头作为图像采集设备。在图像处理中，采用定向梯度直方图(Histogram of Oriented Gradient, HOG)方法识别人数，采用背景减法识别活动水平。本系统实现在树莓派3上作为单板计算。测试结果表明，该系统能够对3米~ 9米范围内的人进行检测，对30厘米~ 150厘米范围内的2人进行区分，并能区分小、中、高活动水平。测试结果表明，所设计的模糊逻辑控制的工作温度最低为21℃，最高为27℃，符合SNI委员会制定的热舒适标准。工作温度与测量室温之间的差异仅在0.2°C至1.2°C之间。

OSD PSE is the Indonesian Government's Certification Authority (CA) for National e-Procurement System and later named OSD PSE G2. It has a unique hierarchical structure under the OSD Lemsaneg. As an Issuing CA, the OSD PSE G2 publishes and guarantee the quality of Certificate Policy and Certification Practice Statement (CP-CPS) in order to gain the PKI user's trustworthy. In this article, we analyze the CP-CPS version 1.0 that published by OSD PSE G2. For this purpose, we apply the methodology of PKI Assessment Guidelines (PAG). The quality assessment of this CP-CPS, including its compliance to the related reference/standard, namely: CP OSD Lemsaneg v.1.1; RFC 3647; and CA Business Practice Disclosure Principle on Trust Service Principles and Criteria for Certification Authorities (BPDP-TSPCCA) version 2.0. We finally found that the CP-CPS version 1.0 does not comply with related standard and reference. Hence, the CP-CPS need to be updated following the current condition of OSD PSE G2.
OSD PSE是印尼政府的国家电子采购系统认证机构(CA)，后来被命名为OSD PSE G2。它在OSD Lemsaneg下有一个独特的层次结构。OSD PSE G2作为颁发CA，发布并保证CP-CPS (Certificate Policy and Certification Practice Statement)的质量，以获得PKI用户的信任。在本文中，我们分析了OSD PSE G2发布的CP-CPS 1.0版本。为此，我们采用了PKI评估指南(PAG)的方法。该CP- cps的质量评估，包括其是否符合相关参考/标准，即:CP OSD Lemsaneg v.1.1;RFC 3647;《CA业务实践披露原则:认证机构信托服务原则和标准》(BPDP-TSPCCA) 2.0版。我们最终发现CP-CPS 1.0版本不符合相关标准和参考。因此，需要根据OSD PSE G2的当前情况更新CP-CPS。

The design of an optimal BLDC motor with high efficiency is the most important thing especially for electric scooter application since its performance is very depended on power output of BLDC. This paper presented design of 5 kW axial flux permanent magnet of BLDC motor based on Solidwork and Ansys Maxwell. The motor parameters were designed by modeling of physical parameters through calculation, such as number of pole, stator core diameter, and selection of material type. These physical parameters are then designed its blueprint through Solidwork and simulated through Ansys Maxwell with Rmxprt (Rotational Machine Expert) feature. The analyzed electrical parameters were speed, efficiency, flux density, and losses. The results showed the designed axial flux permanent magnet motor BLDC with 12 slot stator and 8 pole rotor presented the torque = 9.5 Nm, rated speed = 5050 rpm, and motor efficiency = 94.49 %.

This system was designed and made to measure the rotation angle of plane of polarization on analyzer, light intensity, and value of magnetic field, where as the analyzer angle setting is done by using a stepper motor which connected to the lens of analyzer by a gear set, for the light intensity the writer measured it with a lux meter IC BH1750, and the magnetic field measured based on the current which given by constant current power supply. Number of pulses on the stepper motor and the data from the IC BH1750 is being acquired using a microcontroller. In this research, the writer used two variable wave length from different color on 30 watt LED as the light sources, all of these light sources are being controlled by the microcontroller. Based on this research, the writer conclude that there are transfer function (p= 17.832θ), where (θ) is the rotation angle of analyzer and (P) is the pulse that is generated from the stepper motor. All of the control system is controlled by a microcontroller that is integrated with the computer.

More than half of Indonesia area haven't covered by the mobile network. Therefore an ad-hoc network delivering VoIP technology can be the solution for this problem. This paper presents the research using Raspberry Pi with Kamailio SIP server and OLSR routing protocol. From the experiment, the network performance shows a satisfying result when compared to the standard made by Indonesian Ministry of Communication and Informatics. Considering Raspberry Pi capability and experiment result, it is possible to use Raspberry Pi for VoIP system in the rural area.
