Alloy anode materials play an important role in zinc electrowinning process. Many kind of alloys can be used as anode materials, the selection of anode alloy directly influence the quality and cost of zinc electrowinning. Pb-Ag alloy anode material has been used generally in zinc electrowinning, however, it is proved the existence of many problems in practice. An important subject that new lead based multi-alloy applied to zinc electrowinning has been confirmed. Contrast testing study on the performance between Pb-Ag alloy anode plate and lead based multi-alloy anode plate was carried out on the basis of the research status, such as the output of precipitated zinc, the quality of electrolytic zinc, power consumption and anode life. It was found that when the technology of alloy-making had a breakthrough, the Pb-Ag alloy anode could be replaced by lead based multi-alloy anode under the condition that electrowinning technology was adapted, and the production costs could also be reduced.

Today, the increase in reactive power consumption far exceeds the increase in active power consumption. Due to the increasing demands of the end-users for the quality of the supply of electricity, the problem of joint selection of rational sections and places of installation of reactive power compensation in the distribution line becomes relevant. A mathematical model and algorithm allowing such a choice are proposed. The mathematical model can be used both in the design of new lines and in the reconstruction of existing lines. An example is given.

Processes of electrolytic application of metals are used in order to obtain pure coatings, single - or multilayer. Appropriate selection and proper execution contribute to the improvement of product quality, which affects its proper and long functioning. Production costs are not necessarily high. They depend mainly on the proper selection of the coating. The article presents the results of the use of generalized objective function for selection of galvanic coating on metal parts. There were used following criteria in order to characterize the quality (usability): corrosion resistance, mechanical properties, physical properties, gloss, roughness, and economical criteria. Presented method of determining the objective function can be used to choose the optimal coatings for specific service conditions or customer requirements. Presented method of determining the objective function in the design process of the surface layer makes it possible to assess the impact of various factors on the quality of the product and thus gives a chance to make the right choice.

Abstract: Material selection and innovative and creative designs are needed as a medium for reducing production costs by changing the design of a product but still paying attention to the safety of its users. The problem that occurs in the surrounding community is the lack of public knowledge about the selection of materials that can risk accidents that will be experienced by users which can be caused by the material not being strong enough to support the load it gets. Innovative and creative design aims to reduce the mass of the material but still refers to user safety. Inappropriate design can increase the risk of accidents and wasted costs in the production process. The method used in this community service is a material selection workshop and an introduction to machine design using solidworks software. Therefore, this community service will greatly help the community in the Karang-tempel Village, East Semarang District, increase their insight into the selection of materials and innovative designs as an increase in the quality of production and ensure the safety of users.          Keywords: creative; desain; inovative; material selection; workshop Abstrak: Pemilihan material dan desain yang inovatif dan kreatif sangat diperlukan sebagai media pengurangan biaya produksi dengan merubah rancangan suatu produk akan tetapi tetap memperhatikan keselamatan dari penggunanya. Permasalahan yang terjadi di masyarakat sekitar akan kurangnya pengetahuan masyarakat tentang pemilihan material yang dapat berisiko akan terjadinya kecelakaan yang akan dialami pengguna yang dapat disebabkan oleh material tidak cukup kuat untuk menopang beban yang didapatkannya. Desain yang inovatif dan kreatif bertujuan sebagai pengurangan massa dari material akan tetapi tetap merujuk kepada keselamatan pengguna. Desain yang tidak sesuai dapat meningkatkan risiko kecelakaan dan pemborosan biaya pada proses produksi. Metode yang digunakan pada pengabdian masyarakat ini adalah workshop pemilihan material dan pengenalan rancang bangun mesin menggunakan software solidworks. Oleh karena itu pengabdian kepada masyarakat ini akan sangat membantu mas-yarakat di lingkungan kelurahan Karang-tempel, kecamatan Semarang Timur untuk menambah     wawasannya terhadap pemilihan material dan desain yang inovatif sebagai peningkatan kualitas hasil produksi dan menjamin keselamatan dari pengguna.Kata kunci: desain; inovatif; kreatif; pemilihan material; workshop

The article discusses the reasonsfor an expert to participate in legal proceedings. The gnoseological reason for that consists of the bad quality of materials subject to examination that renders the examination either completely impossible or compromises objective, reasoned and reliable assessment of the findings. The procedural reason consists ofa proscription for an expert to collect evidence himself or herself. The author investigates into the ways of how an expert can participate in legal proceedings. If the defense invites an expert to participate in the proceedings, then it is recommended that his or her involvement should be in the presence of attesting witnesses and recorded in the protocol. In the course of the legal proceedings an expert has the following tasks: adding initial data, acquiring new initial data, understanding the situation of the incident, acquiring new objects to be studied, including samples for examination. An expert’s participation in legal proceedings differs from the participation of a specialist or an examination on the scene of the incident. The author describes the tasks that an expert solves in the course of legal proceedings, the peculiarities ofan investigation experiment practices, the selection of samples for an examination, inspection, interrogation.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor. Software and hardware used in thisthesis work are DCS CENTUM VP Yokogawa.
