Penghilangan Mikroorganisme dalam Air Minum dengan Dielectric Barrier Discharge
Get PDFMicroorganisms such as Escherichia coli in water are a component that is difficult to remove in conventional water treatment systems. Several systems have been implemented to reduce levels of microorganisms is the use of disinfectants, the membrane filtration and activated carbon absorption. These systems have several weaknesses, so that not all microorganisms can be removed from drinking water. The plasma system is an applicable technology for removing organic compounds and microorganisms in drinking water. By creating plasma in water will produce several of active species such as OH-, H+, O3 and H2O2that has a high oxidation potential, decompose organic compounds and kill microorganisms in the water significantly. This paper will describe the removal of microorganisms in drinking water using a plasma system by the method of dielectric barrier discharge (DBD ). The results howed that the pH of drinking water produced in the range 6.5 to 7.3. The higher voltage causes the higher the conductivity, temperature and ORP water. Removal efficiency for the content of microorganisms Coli Fecal and Coliform in the range 99.2 to 100% after water was injected voltage of 13-17 kV for 10 minutes

Solving Human Resources Management Of Construction Labors Using Mobile Community Network
Get PDFA construction labor works on a project based on adetermined interval time. If the construction project is donethen the labor has to find another one. Based on theinterviews conducted to some construction labors in BandaAceh and Medan, they depend totally on the networking andfriendship among the labors in finding a project. sOn theother hand, the labors can survive only for seven days if he isnot working. The proposed solution is developing a jobsearch system for the construction labors using mobileapplication. This system is built using JavaME, RecordManagement Store (RMS) as the storage media, and ShortMessage Service (SMS) as the data connection. This systemapplies distributed system thus it will not cause the processbecomes slow because the limited memory of the cellularphone. This system provides the construction laborsspecification which is needed by the employer and the list ofconstruction labor specification. Job searching will beprocessed again once the labors done with a project. In thisway, the construction labors will continually contracted witha project. Using this system will solve the problem faced bythe construction labor in finding a project and finally achievetheir economis growth
Dissemination of Metal Detector Technology for the Geumpang, Pidie Community in Managing Gold Mining Risks
Get PDFArtisanal and small-scale gold mining (ASGM) activities in Geumpang, Pidie, are commonly practiced using unsafe and unregulated techniques, exposing local communities to environmental and health risks. This community service activity aimed to introduce metal detector technology to enhance safe and effective gold prospecting while reducing mining-related hazards. The program involved 20 local participants and was implemented using a service-learning approach that combined expert-led technical training with participatory community engagement. Hands-on training using Minelab GPX6000 and GPZ7000 detectors was delivered by international practitioners and academic facilitators. The results indicated a 72% improvement in participant knowledge, 85% tool operation proficiency, and a 70% increase in risk awareness. Furthermore, the community proposed a rotational tool-sharing system, demonstrating a commitment to sustainability. The initiative highlights how contextual technology transfer and collaborative training can contribute to safer mining practices and support sustainable development goals in remote mining communities
Analisa Tekno-Ekonomi Perencanaan Teknologi Long Term Evolution (LTE) di Kota Tasikmalaya
Get PDFKebutuhan komunikasi berbasis data terus meningkat. Seperti sekarang banyak gadget canggih, namun tanpa jaringan internet yang baik hanya akan berfungsi seperti ponsel biasa. Lemahnya dukungan berujung pada kelambatan dan sekali lagi vendor jaringan mencoba memberikan solusi kepada para operator. Kali ini harapan baru dengan teknologi Long Term Evolution (LTE), sebuah teknologi seluler generasi keempat (4G). Pada kesempatanini dilakukan analisa perencanaan teknologi LTE di Kota Tasikmalaya sebagai bahan pertimbangan dalam perencanaan untuk operator yang akan membangun jaringan LTE. Hasil perhitungan menunjukan bahwa nilai spesifikasi jaringan yang direncanakan untuk luas sel dan jarak jangkauan eNode B. Untuk mencakup seluruh Kota Tasikmalaya diperlukan 21 buah eNode B, dan juga diperhitungkan analisa ekonomi berdasarkan data yang ada di lapangan berupa jumlah penduduk Kota Tasikmalaya untuk mengetahui kelayakan investasi suatu perencanaan. Dan berdasarkan perhitungan NPV diketahui bahwa perencanaan teknologi LTE adalah layak untuk dilakukan

AI-Powered Branding by Utilizing ChatGPT for the Promotion of Competitive MSMEs (SDGs9)
Get PDFKarangsong Village in Indramayu Regency holds substantial economic potential in the fisheries, tourism, and creative industry sectors. However, more than 70% of Micro, Small, and Medium Enterprises (MSMEs) in the village still rely on conventional marketing methods. Only around 30% utilize social media, and less than 10% have adopted digital branding strategies effectively. The main challenges faced by these MSMEs lie in the areas of production, business management, and marketing particularly in terms of product quality standardization, financial recordkeeping, inventory management, and the implementation of effective digital promotion strategies. This community engagement program aims to enhance the competitiveness of MSMEs through the application of Artificial Intelligence (AI), particularly by utilizing the ChatGPT platform as a tool to improve the efficiency and quality of digital branding. The program is conducted in four stages: socialization to introduce the concept of AI and ChatGPT, technical training and mentoring, monitoring and evaluation of AI implementation outcomes, and the preparation of a final report along with sustainability recommendations. The solutions offered include using ChatGPT to recommend product innovations, develop business plans, generate promotional content, write social media copy, and create customer engagement chatbots. University students are actively involved in the implementation of the program, in alignment with the Merdeka Belajar Kampus Merdeka (MBKM) initiative. Additionally, the program supports the achievement of Sustainable Development Goal (SDG) 9, which focuses on Industry, Innovation, and Infrastructure. The expected outcomes include AI-based marketing strategies that are practical and implementable for MSMEs, as well as enhanced customer engagement through digital media. This initiative is expected to strengthen the digital capacity of Karangsong's MSMEs in facing the challenges of the digital economy
Desain Layout 1-Stage ADC Pipeline 80Msps dengan Mentor Graphics 0,35m untuk Aplikasi Kamera Kecepatan Tinggi
Get PDFDesign layout 1-stage pipeline is part of the 8-stage pipeline 80 Msps ADC. Layout 1-stage pipeline consists of 3 units : op-amp, switch capacitor, precision comparator with latch. Pipeline ADC works gradually and requires synchronization of digital output 8 stage by using a unit delay circuit (D-FF). Pipeline ADC requires pulse rate (clock) generator to support its work. Units OP-AMP transconductance CMOS components designed with the correct specification ADC applications with capacitive loads, with a large input impedance and minimize noise. The precision comparator has Vos (offset voltage) approximately equal to 0V. The capacitor switch designs use NMOS switch as a switch for the sampling and multiplying. In the sampling phase and multiplying processes, the ADC requires a clock pulse with a non-intersect mode (lapping). The width of non-overlapping period was adjusted to the time of constance in the sampling process and multiplying. The total number of each pulse period equal to 12.5 ns or equal to the frequency of 80MHz. In the 1-stage layout an additional correction capacitor was required to correct residual voltage. The total area of the layout 1-stage pipeline ADC is 1-bit 200 m x 98m
