Analisis Persepsi Masyarakat Terhadap Kinerja Layanan Angkutan Khusus Pariwisata Jogja Heritage Track
Full text linkReferring to the vision and mission of the development of the Special Region of Yogyakarta, the local government is committed to advancing tourism as one of the leading sectors. One form of attention to cultural tourism is by revitalizing the Cosmological Axis area. The Cosmological Axis is an area in the form of an imaginary straight line between Tugu-Malioboro-Keraton to Panggung Krapyak which has been rearranged to its original shape. In order to support the Cosmological Axis towards world cultural heritage, the local government launched an educational tourism program called Jogja Heritage Track which is a tourist transportation service with a city tour concept. One year after the initial launch in July 2022, it was deemed necessary to evaluate the performance of the Jogja Heritage Track bus in terms of the service received by passengers. Gap Servqual was chosen as the analytical method in this study to assess how big the value of the gap that occurs between the level of service received by passengers and the expected performance. Data collection was carried out by distributing questionnaires to passengers and in-depth interviews with regulators and operators. Based on passenger perceptions, the quality of Jogja Heritage Track bus services is not completely good and still requires improvement. This is illustrated by the gap value of -0.09 and the service quality value of 0.98. Of the five Servqual dimensions (Physical Evidence, Reliability, Responsiveness, Assurance and Empathy), the Empathy dimension is positive, which means that service performance on the Empathy dimension is in line with passenger expectations
Pengaruh Sputtering TiN Terhadap Kekerasan Permukaan dan Struktur Mikro Pada Material Stainless Steel 316L
Full text linkMetal-based biomaterials are highly rust-resistant. A key property that metal-based biomaterials must possess is excellent biocompatibility with living cells. AISI 316L is widely used for implantation purposes in orthopedic surgery due to its good mechanical properties and low price, but AISI 316L lacks good biocompability with the body so that implant materials with AISI 316L material cannot be used for a long period of time. This research aims to study the effect of TiN sputtering process on AISI 316L stainless steel material and titanium target material as a coating on the surface. The sputtering process was carried out on the 316L surface a variation of sputtering time of 60, 90, 120 and 150 minutes with a gas variation ratio of 20% N2 and 30% N2, using a voltage of 5 kV and the current used was 5-10 mA at a pressure of 0.079 mbar. The results of hardness testing on 316L material with TiN sputtering treatment can increase the hardness on the surface of the material. The surface hardness value of the effect 30% N2 gas ratio and sputtering duration of 90, 120 and 150 minutes respectively is 305 kgf/mm2, 310 kgf/mm2 and 334 kgf/mm2, this treatment has significant increase in hardness at 90, 120, and 150 minutes. Microstructure testing to measure the thickness of the electroplating layer results, showing that the thickness of the layer resulting from the sputtering process with a gas ratio of 30% N2 and a TiN sputtering duration of 120 minutes shows there are vacancies on the surface inserted by hard TiN atoms
Rancang Bangun Mesin Pengupas Kulit Ari Buah Kelapa Menggunakan Metode Verein Deutshcer Ingenieure (VDI) 2222 di PT PECU
No full textCoconut is a plant that has many benefits and can be utilized as a whole starting from the stem, meat, coir, shell, water, and coconut cuticle. PT Pacific Eastern Coconut Utama (PECU) is the largest coconut processing company in Java Island with its main products, namely liquid (Coco Day and Liquid Coconut Milk) and non-liquid (Desiccated Coconut and Coconut Powder). Before coconuts become final products, namely non-liquid products (Desiccated Coconut and Coconut Powder), these coconuts will go through the process of stripping the coconut cuticle. In this process, PT PECU still uses manual tools which require more time and effort and not all operators have the same abilities. Therefore, companies need to design appropriate tools using the Verein Deutscher Ingenieure 2222 (VDI 2222) method. This method is used to develop and design products, systems or tools by considering various aspects, such as user needs, security and efficiency.The results of this design can help companies to increase company productivity, do not endanger the operator, and the machine can be operated easily
Sistem Kontrol Pneumatik pada Inlet Guide Vane Turbin Air Mikro Hidro
Full text linkIndonesia has 377 MW of micro-hydro potential as an energy source for electric power generation, with the main component being water turbines. Important parameters controlled in electricity generation are generally the rotation and frequency of the turbine-generator which are regulated automatically in this case through a guide vane. This research explores the potential use of pneumatic control with an Arduino microcontroller as an alternative in regulating the Inlet Guide Valve (IGV) opening in a low-power Micro Hydro Power Plant (MHP). Hydraulic systems that are generally used in large power water turbines have constraints on maintenance costs and high processing time. By utilizing pneumatic control, this research uses Arduino to control the guide vane movement through a pneumatic cylinder. Tests were conducted with separate programs to read the turbine rotation, activate the solenoid valve, and adjust the power on the guide vane simulator. The test results show that the system successfully controls the rotation of the water turbine effectively. The conclusion of this research is that there is an inversely proportional relationship between the opening of the guide vane and the rotation of the water turbine, as well as successful control through a pneumatic system with Arduino. This research contributes to the development of low-power MHP technology with more efficient maintenance costs
