Diskless server is a cluster computer network which uses SSH (Secure Shell) protocol to grant the client an access to the host's directory and modify it's content so that the client don't need a hardisk (Thin Client). One way to design a diskless server is by utilizing "Linux Terminal Server Project", an open source-based script for Linux. However, using Linux has it own drawback, such as it can't cross platform for running an aplication based on Windows system which are commonly used. This drawback can be overcomed by using a compatibility layer that converts a windows-based application's source code. The data which will be monitored is the compatibility layer implementation's result, and the throughput, packet loss, delay, and jitter. The result of measurement from those four parameters resulting in "Excellent" for throughput, "Perfect" for packet loss and delay, and "Good" for jitter.

The development of technology allows one to obtain other people's spatial position data. One mobile technology that utilizes spatial data as a supported factor is location-based services. The large number of employees at the PT.XYZ causes the presence of a controlled process to be under control, and even tends to be questioned. Because it takes a GPS-based presence system on android that is expected to be a solution of the problems that occur at this time. The system development method used is a six-step R&D method, consisting of: Research and information gathering, Planning, Development of initial product forms, initial field testing, major product revisions, main field testing. The final result is the prototype of the Ganesha Employee Presence System Operations. The test results on the system shows the employee attendance system can run on the android platform. The system only responds to presence based on the position of the employee's coordinates with office coordinates. Besides checking the presence process is also based on devices that have been approved in the system. 

AbstractCikiwul is a village located in Bantargebang district. Where the Bantargebang location is a final waste collection site which is the main disposal site for around 6,500 tons of waste per day from all over Jakarta. Plastic bag waste is a serious enemy for environmental sustainability. The difficulty in breaking down makes plastic waste need proper handling so that it does not accumulate. One way is to do an ecobrick. Ecobrik is a plastic waste management method that is very easy for everyone to do and has a very high impact on environmental conservation. We do community service by disseminating the benefits of ecobricks, as well as providing training on how to do ecobricks together with Cikiwul residents. Training using the zoom platform, adapting to current conditions, activities are carried out by discussing and providing training videos on how to make ecobricks. It is hoped that this activity can reduce plastic waste, which its usefulness can be maximized into new objects that have useful values.AbstrakCikiwul merupakan salah satu kelurahan yang berada pada kecamatan Bantargebang. Di mana lokasi Bantargebang merupakan tempat penampungan sampah akhir yang menjadi tempat utama pembuangan sekitar 6.500 ton sampah per hari dari seluruh wilayah Jakarta. Sampah kantong plastik menjadi musuh serius bagi kelestarian lingkungan hidup. Kesulitan dalam terurai, menjadikan sampah plastik perlu penanganan yang tepat agar tidak semakin menumpuk. Salah satu caranya adalah dengan melakukan ecobrick. Ecobrik merupakan metode pengelolaan sampah plastik yang sangat mudah dilakukan setiap orang dan sangat tinggi pengaruhnya bagi pelestarian lingkungan. Pengabdian masyarakat yang kami lakukan dengan mensosialisasikan manfaat ecobrick, serta memberi pelatihan cara melakukan ecobrick bersama dengan warga Cikiwul. Pelatihan menggunakan platform zoom, menyesuaikan dengan keadaan saat ini, kegiatan dilakukan dengan berdiskusi dan memberikan video pelatihan cara pembuatan ecobrick. Diharapkan dengan adanya kegiatan ini, dapat mengurangi sampah plastik, yang dimaksimalkan kegunaannya menjadi benda baru yang memiliki nilai guna.Â
