Penilaian Tingkat Transparansi Musyawarah Perencanaan Pembangunan (Musrenbang) Kota Surabaya
Get PDFE-musrenbang hadir dengan harapan dapat memenuhi perwujudan tata kelola pemerintahan yang baik (good governance). Dalam konsepsi good governance, transparansi publik menjadi sebuah prioritas tersendiri karena transparansi dapat memperkecil terjadinya kesalahan, sehingga masyarakat dapat turut menilai dan mengkritisi. Namun, dalam praktik musrenbang Kota Surabaya, masih terdapat temuan-temuan yang menuntun pada permasalahan transparansi kebijakan publik, diantaranya adalah elite capture, ketidaksesuaian data, dan hambatan-hambatan lain pada sistem. Hal seperti ini merupakan sebuah gap tersendiri mengingat Kota Surabaya juga bertindak sebagai kota prestatif dan percontohan bagi banyak wilayah lain di bidang kepemerintahan.Hasil analisis menunjukkan bahwa dengan teknik analisis skoring Indeks Kepuasan Masyarakat, transparansi musrenbang Kota Surabaya dinilai baik, dengan klarifikasi transparansi variabel termasuk pada kategori baik dan sangat baik. Berdasarkan tipologi penilaian yang telah dilakukan sesuai klaster wilayah, Surabaya Selatan merupakan wilayah Surabaya dengan tingkat transparansi tertinggi dan mendapatkan label transparansi sangat baik (nilai indeks 83,365). Sedangkan Surabaya Barat merupakan wilayah Surabaya dengan tingkat transparansi terendah dan mendapatkan label transparansi baik (nilai indeks 74,881). Selain itu, diketahui pula bahwa variabel yang menjadi titik lemah pelaksanaan musrenbang Kota Surabaya saat ini adalah variabel “keterbukaan implementasi program
Experimental Study of Single Stage Centrifugal Pump Characteristics and Cussons Friction Loss Apparatus
Get PDFWater is a primary need for human life. Because of its important use, an integrated system was built consisting of pumps and pipes to distribute water. The phenomenon of energy loss is found in the process of distributing water using pumps and pipes. To understand the energy loss phenomenon that occurs, an experimental test is carried out on a piping installation. Fluid mechanics and turbomachinery laboratories have experimental test equipment in the form of CUSSONS friction loss in pipe apparatus with a single-stage centrifugal pump to study the energy loss phenomenon that occurs in piping installations. This test equipment is composed of two kinds of pipe materials, namely PVC and acrylic, with variations in pipe diameter of 0.75 and 1.0 inch, flow meters in the form of venturi and orifice, pipe fittings in the form of elbow 45◦ , long radius elbow 90◦ , short radius elbow 90◦ , a valve in the form of ball-valve and pump connected to the NEWMAN electric motor which has a power of 1.5 HP and a rotational speed of 2850 RPM. The pressure drop in the piping installation was measured using a mercury manometer, the increase in pump pressure was measured with a pressure gauge, and the current and voltage of the motor pump were measured using a clamp meter. The flow rate for the installation was varied between 10L/min to 55 L/min with an increase in the flow rate of 5 L/min for the data collection on straight-pipe line I, fittings, and ball valves, on straight-pipe line II the variation of discharge only reached 40 L/min, while the variation of discharge for the flow meters was from 10 L/min to 30 L/min with an increase in the flow rate of 2 L/min for the orifice and 4 L/min for the venturi. Based on the experimental test data, it was found that the loss coefficient value (Kl) for K90= 0.58, for K45= 0.38, KBV = 0.62, and KLRE= 0.611. Relative roughness (e/D) on pipe line I= 0.0043 and pipe line II = 0.024. The coefficient of discharge (Cd) on the venture-type flow meter Ce= 0.91 and Co= 0.72 at maximum discharge. Maximum pump efficiency (ηp) was 27.1% when the pump head= 18.79 m

The Barrier and Driver Factors of Building Information Modelling (BIM) Adoption in Indonesia: A Preliminary Survey
Get PDFBuilding information modeling (BIM) changes institutions, businesses, business models, education, workplaces and careers. For an asset owner the implementation of BIM should seen as a business change program that can potentially impact their ‘value proposition’. BIM can enable strategic business outcomes. BIM is useful for geometric modelling of a building's performance and it can assist in the management of construction projects. The construction industry in the world has recognized the benefits of BIM, therefore many large projects in developed countries have used BIM. In Indonesia, lately BIM has received more attention from construction industry players, even the Indonesian government through the public works agency issued guidelines for BIM adoption in 2018 with reference to developed country references such as Singapore. Many benefits can be obtained from the implementation of BIM, but the level of BIM adoption in Indonesia is still low. Thus, it warrants a study such as the present to determine what are the actual barriers that hamper its implementation and what are the driving factors that could enhance its pace of implementation in the Indonesian construction industry. This paper is an initial stage of the research to determine the barriers and driving factors of building information modelling (BIM) adoption in Indonesia. Following the variable identification from the literature, a preliminary survey involving eleven experts were conducted to verify several variables that have been identified from the literature to be used for the questionnaire survey. According to the experts’ opinion, it was found that 16 variables were considered relevant to measure the barriers of BIM adoption in Indonesia and 18 variables were considered relevant to measure the driving factors of BIM Adoption in Indonesia. The three most relevant barriers BIM adoption in Indonesia attributes were also determined according to the experts’ opinion, that are (1) Lack of BIM expert; (2) Lack of understanding about BIM and its benefits; (3) Resistance to change. The three most relevant drivers BIM adoption in Indonesia attributes were also determined according to the experts’ opinion, that are (1) Willingness/intention; (2) Technological factors; (3) Organizational cultur

Automatic Self-checkout System Using SURF, Brute Force Matcher, and RFID for Payment Process Optimization at Supermarket
Get PDFA long queue is common at a conventional supermarket. It is caused by inability of cashier to handle the task. Cashier could have an inconsistent performance, untrained skill, and fatigue. In addition, odd price tags could engage unnecessary conversation in giving change. This resulted on the service provided to be longer. The current solution for this problem is Radio Frequency Identification (RFID) and debit card usage. As per our survey at local supermarket, the usage of RFID could extend cashier service by up to five minutes fifteen seconds for the purchase of six test goods, meanwhile the cash took up to three minutes 23 seconds. Intelligent self-checkout system has been proposed but requires a high-end graphics card. In this study, we propose an automatic self-checkout system based on Speeded Up Robust Features (SURF), brute force matcher, and RFID for payment process optimization at supermarket. The system consists of an image scanner, a conveyor set which moves the customer’s goods into scanning area. After the goods is detected, customer pay the displayed price using RFID card. The result of our experiment has 77.78% detection rate and 16 seconds of payment process. Compared to traditional method, our system is twenty times faste
