Implementasi Kebijakan Sertifikasi Bendahara (Studi Kasus Di Kantor Pelayanan Perbendaharaan Negara Medan II)

This study aims to analyze the implementation of the treasurer certification policy in the APBN management work unit at KPPN Medan II. This study uses a qualitative approach where the researcher is the key instrument, the data collection technique is trangulation (observation, interviews, and documentation), the data obtained tend to be qualitative data, the data analysis is qualitative, and the results of qualitative research are to understand the meaning and construct phenomena. implementation of the treasurer certification policy. The results of the study indicate that the implementation of the treasurer certification policy has not yet reached the ideal condition, namely the achievement of all certified treasurers no later than 4 years since Presidential Regulation Number 7 of 2016 concerning Certification of Treasurers of the State Budget Management Work Unit comes into force. This is due to inconsistencies in policy implementation due to the non-compliance of the Head of the Work Unit in fulfilling the commitments in the Statement of Ability for the Treasurer to take the treasurer certification at the first opportunity. In addition, the incentive indicator is also one of the inhibiting factors for treasurers from participating in treasurer certification because treasurers feel that the workload, risks, and responsibilities are not balanced with the rewards received and the treasurer's career path is unclear.

Investigation of Airflow Distribution and Contamination Control with Different Schemes in an Operating Room

Controlling contamination via proper airflow distribution in an operating room becomes vital to ensure the reliable surgery process. The heating, ventilation, and air conditioning (HVAC) systems significantly influence the operating room environment, including temperature, relative humidity, pressurization, particle counts, filtration, and ventilation rate. A full-scale operating room has been investigated extensively through field measurements and numerical analyses. Computational fluid dynamics (CFD) simulation was conducted and verified with the field measurement data. The simulation was analyzed with three different operating room schemes, including at-rest conditions (case 1), normal operational conditions with personnel (case 2), and actual conditions with personnel inside and some medical equipment blocking the return air (case 3). The concentration decay method was used to evaluate this study. The results revealed that the contamination concentration in case 1 could be diluted quickly with the average value of 404 ppm, whereas the concentration in case 2 slightly increased while performing a surgery with the average value of 420 ppm. The return air grilles in case 3, blocked by obstacles from some medical equipment, resulted in the average concentration value of 474 ppm. Other than that, the contaminant dilution could be obstructed dramatically, which revealed that proper and smooth airflow distribution is essential for contamination control. The ventilation efficiency of case 2 and case 3 dropped around 6% and 17.91% compared to case 1 in the unoccupied and ideal condition. Ventilation efficiency also decreased along with decreasing the air change rate per hour (ACH), while with increasing ACH, the ventilation efficiency in case 3 actually increased, approaching case 2 in the ideal condition.

Multiresponse Particle Swarm Optimization of Wire-Electro-Discharge Machining Parameters of Nitinol Alloys

The conventional process of machining of nitinol alloy which possesses excess strain hardening and low thermal conductivity makes a complex process that leads to extensive wear on the tool and inadequate surface quality. Wire-electro-discharge machining (WEDM) is widely accepted for machining this alloy involving various input factors, namely, P (pulse-on-duration), Q (pulse-off-duration), C, (maximum-current), and V (voltage). Using the PSO (particle swarm optimization) method, the effect of WEDM process factors on multiresponses such as MRR (metal removal rate) and SR (surface roughness) has been investigated. ANOVA was used to create a relationship model between input factors and response characteristics, which was then optimized using response surface methods (RSM). ANOVA revealed that variables A and C are the most significant. When investigated individually, the influence of WEDM process parameters on SR and MRR is contradictory, as no response provides the best process quality. To find the optimal ideal condition for decreasing SR and maximizing MRR, the MOOPSO approach was used. P = 25.47051 μs, Q = 10.84998 μs, C = 2.026317 A, and V = 49.50757 volts were used to calculate the optimal universal solution for machining characteristics (MRRmax = 3.536791 mm3/min and SRmin = 1.822372 μm). PSO enhanced MRR and SR for every optimal combination of variables, according to the findings. Based on the findings, a wide range of optimal settings for achieving maximum MRR and minimum SR are given, depending on the product requirements.

Techno-economic Analysis of Rooftop Photovoltaic System (RPVS) using Thin-Frameless Solar Panels for Household Customers in Indonesia

The availability of thin-frameless solar panels on the market today makes the installation of rooftop Photovoltaic (RPVS) systems more attractive. The purpose of this research is to analyze financially the use of thinframeless solar panels for on-grid RPVS by household electricity customers in Indonesia. The investment cost, the maintenance costs, and the electricity cost savings were involved for the financial analysis, such as Internal Rate of Return (IRR), Net Present Value (NPV), and Pay Back Period (PBP). The calculation is carried out for ideal conditions, the direction of a non-ideal rooftop and the yearly increase of electricity prices is 15 %. The analysis results show that the minimum available rooftop area is still sufficient for the rooftop area needs for solar panel placement, the thin solar panels are safer than standard solar panels, and savings on electricity payments for the return on investment of the RPVS is to be attractive with the IRR > 12 %. The average investment cost of the non-ideal condition is 8 % higher than the ideal condition. This study provides an overview to the policymakers and developers in exploiting the potential of RPVS, especially in Indonesia. For future research directions, this study needs to analyze the technical and economic feasibility of using hybrid smart-grid technology with batteries.

Response analysis of orthotropic steel deck pavement based on interlayer contact bonding condition

In this research the interlayer contact condition was considered between the adjacent layers of orthotropic steel deck pavement, and an interface contact bonding model was applied to simulate the interlayer bonding condition and evaluate the response of deck pavement under vehicle loads. An advantage of this model is that it can simulate not only the full-bond condition but also the debonding condition at somewhere between adjacent layers. The responses of the orthotropic steel deck pavement were calculated and analyzed by the model, and it found that this model is reasonable and credible to evaluate the responses of the deck pavement comparing with the previous researches. The full-bond condition was an ideal condition between adjacent layers, which was prone to underestimate the responses and deformation of the deck pavement. Moreover, the position and size of the disengaging area have a notable influence on the tensile strain at the top of SMA layer and the bottom of GA layer, and the tensile strain of them also increase with the increase of the disengaging area. Finally, the responses of the steel deck pavement changed obviously when the vehicle speed increase, so the suitable speed limit may reduce the responses and deformation for prolonging the service life of the orthotropic steel deck pavement.

Pemikiran Fazlur Rahman Mengenai Politik Islam

Fazlur Rahman is a thinker of Islamic neo-modernism who wants to actualize the teachings of Islam in a unified and solid framework, where one aspect and the other are interrelated. Through this approach, he wants the Qur'an to be understood in an integral and total way, so that things that are considered contradictory no longer exist. This effort is his obsession so that humans can capture the messages of the Qur'an holistically. Departing from his concern for the global problems facing Muslims, he offers a solution that is grounded in the differences between normative Islam and historical Islam. From this distinction, Fazlur Rahman conducted a comprehensive reconstruction of Islamic scholarship. The reconstruction he did refers to the original and definite Islam. For this reason, he suggested that the Qur'an as the main source of Islam needs to be interpreted as a whole and not to interpret it fragmentarism (paragraph verses), namely an interpretation that is able to understand the Qur'an as a whole, so that the theological, legal, political aspects and ethics in the teachings of the Qur'an into a unified whole. Fazlur Rahman argues that the purpose of the Qur'an is to establish an ethical and egalitarian society. So, Islamic society is formed because of Islamic ideology. The ideal condition of the Islamic social order is "which calls for good and prevents evil". This is in order to realize the implementation of politics based on Islamic ideology which cannot be separated from the Qur'an and Sunnah.

Processes Standardization: A Case Study in the Form of Supply in a Company of the Two Wheels of Manaus

This article aims to study the application of standardization techniques in a two-wheel hub company in the city of Manaus, more specifically in the subassembly sector of the chassis, responsible for the preparation of parts to supply the assembly line. The methodologies used were the 5S methodology, which is proven very effective in identifying and eliminating waste and increasing efficiency; the standardization of intermediate stock, to improve the performance of the purchasing and business sectors, and finally, the PDCA cycle, to identify needs and find suitable, low-cost solutions. From the data collected, the problem was defined as the three worst parts, which are the mudguard, rear fork, and top cover, as it was found that they are recurrent in more than 50% of the models produced. These defects are due to the improper storage of the parts, which present scratches and beat marks. The need to establish an ideal condition of ideal storage was raised, and a manual was elaborated in which basic actions are listed to avoid small defects. After applying the mentioned tools and methodologies, the company managed to reduce the occurrence of small defects.

Synthesis of nano-porous ZNO as pigment for white silicone thermal control coating and investigation of structure, optical and thermal properties

Purpose The harsh environment of space, especially radiation of direct solar rays, can potentially raise the temperature of the spacecraft to harmful levels. Thermal control coatings (TCCs) fix the thermal condition of the spacecraft acceptable for its components. This is possible by diffusely reflecting all effective ultraviolet (UV), visible (VIS) and near infrared (IR) (NIR) wavelengths of solar radiation and emmition of IR energy. The most commonly used TCCs have used ZnO as a pigment, but absorption of the UV light by ZnO pigment can change the ideal condition of these TCCs. The aim of his study is the using the porous ZnO particles as pigment to prevent the UV absorption. Design/methodology/approach To enhance the efficiency of these coatings, in the present study, nano-porous zinc oxide particles were synthesized and used as pigments for white TCCs. Findings The results revealed that the proposed TCC (TPZ), Thermal control coating with porous ZnO had better reflection (scattering) and emittance properties in comparison with the coating using ZnO as a pigment (TZ coating); so this coating had a solar absorptance value equal to 0.141, whereas this value for TZ was 0.150. Furthermore, TPZ showed higher thermal emittance (0.937) in comparison with TZ (0.9). These changes were because of the improvement in the refractive index, shape and surface area of the pigments. The general trend of the scattering coefficients for the prepared coating, as calculated from the Kubelka–Munk equation, showed that scattering was more efficient in the UV region, as compared with the TCC containing ZnO pigments. Originality/value This type of pigment for the first time is evaluated in TCCs.

Living in Generosity: The Making of a Refugee Resettlement Centre

<p>Generosity naturally reflects the idea of abundance, larger or plentiful. However, generosity as a language in architecture is vaguely understood, as it has neither a particular scheme nor definite form. This thesis focuses on the idea of generosity in architecture by exploring the language of generosity in providing a generous living for refugees resettling in New Zealand. It concerns the condition of living within a refugee resettlement centre when refugees spend their first six-week orientation program to prepare them for a new life in New Zealand. Through design-led research process, the project takes the concept of elementary geometry from children’s drawing of a house and evolves by extracting the language of generosity to form an architecture. Anything that could be simple to us could mean more to others. Hence, the act of provocation in the simplicity of form, scale, scheme, and colour could transform our perception on “generosity”, and thus it gives the potential for architecture to create an ideal condition of living for future refugees resettling in New Zealand.</p>
