PRIORITAS PEMELIHARAAN JALAN BERBASIS TREATMENT PRIORITY INDEX (TPI) DI JALAN PERKERASAN ASPAL
Get PDFThe increase in the number of vehicles and economic growth in the city of Semarang puts significant pressure on road infrastructure. So it is necessary to prioritize maintenance on several road sections. This research uses the Treatment Priority Index (TPI) approach to identify road repair priorities in Tembalang District, Semarang City. Data on road conditions and daily traffic volume are variables in the TPI analysis and the data is analyzed using the Provincial District Road Management System (PKRMS). The results of the TPI analysis obtained road sections with critical conditions, especially Telumpak (TPI: 26.2) and Salak (TPI: 25.7). These sections require immediate repairs to ensure the safety and comfort of road users. This research provides a basis for information for policy makers to allocate resources efficiently, ensure sustainable road infrastructure, and support effective mobility in Semarang City, especially in Tembalang District

APLIKASI MANAJEMEN KEUANGAN DAN AJUAN HAK CIPTA PROSES PRODUKSI PRODUK USAHA KECIL MENENGAH (UKM) ISNAINI CRAFT KABUPATEN SEMARANG
Get PDFRecording financial reports is an important aspect of a business activity. Financial reports are used as a presentation of financial information used by both internal and external parties for business activities. Accounting practices are a solution to problems that often occur in micro, small and medium enterprises (MSMEs), namely financial management problems. So far, UKM Isnaini Craft has not made regular financial records, let alone made financial reports. So far, SMEs still mix household finances with business finances. This situation often becomes a problem in the smooth production and marketing of the business. The second problem in the New Normal era, the government wants changes to SMEs to improve performance in the fields of finance, production, marketing and resources. In terms of marketing performance, UKM Isnaini Craft needs help in its efforts to achieve competitive advantage by increasing the number of products that obtain Copyright Certificates from the Ministry of Law and Human Rights. Protection of Intellectual Property Rights (IPR) for micro, small and medium enterprises (MSMEs) plays an important role in the era of globalization. Protection efforts are carried out through submitting registration for MSME products that meet the requirements to be granted IPR so that as a consequence the government will provide protection such as patents, copyrights, brands, industrial designs and trade secrets.So, Community Service (PMK) aims to provide an understanding of the importance of financial management for businesses. The technique for resolving the first problem is to provide assistance in making financial records and preparing financial reports. Meanwhile, in the second problem, UKM Isnaini Craft. Will help fund and apply for the acquisition of a Copyright Certificate for 1 Isnaini Craft UKM product to the Director General of Intellectual Property, Ministry of Law and Human Rights

Performance Analysis of H-Type Darrieus Turbine Radial Projection Blades Based on NACA 0018
Get PDFThe H-type Darrieus turbine is a vertical windturbine that is used to convert wind energy into mechanicalenergy by utilizing lift force. This research is aimed at making amodified H-type Darrieus turbine blade model from a NACA0018 profile blade to a NACA 0018 blade with a chordlineprojected radially to the turbine diameter and the second resultis to compare the performance of the NACA 0018-based radialprojection blade to the performance of the NACA 0018 blade.This is preparation for searching literature, design making,manufacture of NACA 0018 blade test specimens and NACA0018 based radial shadow blades, assembly and installation oftest equipment, testing and data collection of wind turbineperformance, data processing and analysis, final results. Thevariables tested were wind speeds of 7 m/s, 8 m/s, 9 m/s, 10 m/s,11 m/s, 12 m/s. The test results show that the higher the TSR, thehigher the resulting power coefficient (Cp) until the maximumCp is reached. After that, the increasing TSR, the resulting Cp isgetting smaller. The test results show that projection bladesbased on NACA 0018 and NACA 0018 blades produce a smallmaximum Cp, respectively 0.082 and 0.124 compared to theDarrieus turbine maximum Cp reference on the vertical turbinecharacteristic chart, which is 0.4. The NACA 0018-based radialprojection produces a lower Cp than the NACA 0018 blade atspeeds of 7 m/s, 8 m/s, 10 m/s, 11 m/s, 12 m/s. At a wind speed of9 m/s the projection blade based on NACA 0018 produces ahigher power coefficient than the NACA 0018 blade. Projectingthe NACA 0018 blade chordline on the track causes the bladecross-sectional area and chordline length to shrink. The higherthe wind speed, the smaller the resulting Cp. The solidwallphenomenon affects turbine performance. Testing without loadat all wind speeds, the projection blade based on NACA 0018produces higher rotation than the NACA 0018 blade. Theparameter of the blade momentum affects the results of theturbine rotation when tested without load
Automatic Fire Extinguishing System Using Smoke Detector and Heat Detector Based on Programmable Logic Controller
Get PDFFire is a disaster that is often encountered throughout the year. This research aims to protect and mitigate the worst possibility of a fire disaster. A PLC automatically creates the work system of this tool, using it as the controller. This tool utilizes two sensors: a smoke detector and a heat detector. Two smoke detectors and one heat detector automatically make the system, each providing input to the PLC. The system splits into two parts: Alarms 1 and 2. If any of the three sensors send input to the PLC, Alarm 1 triggers a buzzer and a yellow light. Alarm 2 occurs if 2 or 3 sensors provide input to the PLC and provide output as the bell lights up, the flash lights up, and the solenoid opens to release Co2 into the room.
