Abstract

Pada mulanya, sistem flat slab banyak digunakan pada bangunan yang beresiko rendah terhadap angin dan gempa. Namun di masa sekarang ini, dengan menggunakan beton dan baja mutu tinggi, sistem bangunan flat slab sudah banyak diterapkan pada bangunan tinggi. Model struktur yang mengunakan sistem flat slab merupakan model struktur tanpa balok, ada penebalan pada kepala kolom yang disebut drop panel, akibatnya semua beban pada pelat lantai akan didistribusikan langsung ke kolom. Dalam tulisan ini struktur gedung dengan drop panel dan tanpa drop panel dimodelkan menggunakan software ETABS Nonlinear v.9.7.4. Tulisan ini bertujuan untuk mengetahui seberapa besar kontribusi drop panel dalam hal ini periode getar alami struktur. Hasil analisis struktur gedung dengan drop panel dan tanpa drop panel menggunakan software ETABS Nonlinear v.9.7.4 telah diperoleh. Hasil analisis menunjukan bahwa drop panel memiliki kontribusi sebesar 8,87% dalam hal ini periode getar alami struktur.

Abstract

This study aims to determine the service quality of electronic fund disbursement of Payment Orders at the Sidikalang State Treasury Service Office and the factors that influence it. This study used descriptive qualitative method. Using interview data collection techniques, observation, documentation and data triangulation. The results of this study indicate that the quality of the electronic fund disbursement service with a Payment Order at the Sidikalang State Treasury Service Office has implemented the dimensions of Tangibility, Reliability, Responsiveness, Assurance and Empathy. There are indicators that have not gone according to the wishes of the work unit, including the inconvenience of the service area including the infrastructure for service support facilities that are outside the service room. Meanwhile, the factors that affect the quality of disbursement of funds with electronic payment orders are the competence of service officers who are not yet uniform, and service facilities and infrastructure supporting service facilities that are less comfortable. It is necessary to uniform the competence of service personnel by participating in education and training, technical guidance, quality control groups or e-learning, increasing the comfort of service facilities and infrastructure and proposing to application developers to carry out application maintenance outside working hours so that application users are not disturbed in carrying out the disbursement process fund.

Abstract

This article describes the design of a data system to integrate energy conversion from photovoltaic measurements connected to the power grid. The software used is visual studio, while the hardware uses polycrystalline photovoltaic (PV) with a capacity of 2.08 kW and several sensors that have been integrated into Arduino. Parameter data in measuring the performance of this PV system consists of temperature and humidity sensors to measure the panel surface, direct current (DC) current sensor, DC voltage sensor. To measure the current and voltage sourced from the electricity network, the module (PZEM-004T) is used. Measurements are designed using a graphical user interface (GUI) on a Visual Studio application that has been interfaced through Arduino programming. The data output on the sensor measurement will simultaneously record the circuit that has been connected to the solar panel and then display it visually in the form of tables and graphs in real time with a delay of 1 minute. The results of PV on grid measurements in sunny weather conditions obtained the maximum value of all measurements with a DC voltage of 221 V, while for an alternating current (AC) voltage of 231.60 V, the DC value reached 1827.17 W while the AC power was 1681 W.
