Quality of E-KTP Services at The Population and Civil Registration Office of Majalengka Regency

Employees at the Population and Civil Registration Office (DISDUKCAPIL) of Majalengka Regency experienced several problems in serving the making of E-KTP, including, the infrastructure at the Majalengka Regency Disdukcapil was inadequate such as an unstable internet network, the number of computer devices that were still lacking, and the number of blanks that were often empty, as well as some elderly people who did not have an E-KTP because they did not understand the system. This study aims to determine the quality of service in the making of E-KTP in the Majalengka Regency Disdukcapil, according to an analysis based on the theory of Zeithami, Parasuraman, and Berry (2008) to measure good service performance referring to Law No. 24 of 2013 in which there are 5 aspects of public services, namely: service procedures, service time and completion, service costs, facilities and infrastructure. The research was carried out using a qualitative method with a descriptive approach. The results of the study show that the quality of e-KTP services at the Majalengka Regency Population and Civil Registration Office is not optimal, because there are still several problems, namely inadequate infrastructure, even though in providing E-KTP servers is quite good and in conveying information about making E-KTP, as evidenced by the active social media from the Majalengka Regency Disdukcapil.

Good Management Practice Is Correlated With Good Performance of Community-Engaged Primary Health Care Facilities in Peru.

Increasing prioritization of quality primary health care (PHC) includes community engagement as a key element to improve PHC performance. We assessed the correlation of good regional management practices with PHC performance in Peru in community-comanaged PHC that is designed with multiple accountability mechanisms. We conducted a secondary analysis of a survey of Dirección Regional de Salud (regional health directorates, DIRESAs) regarding their management of public PHC services with collaborative community involvement by a Comunidad Local de Administración de Salud (Local Community for Health Administration, CLAS). CLAS-run facilities have previously shown evidence of superior performance over standard PHC services. We classified survey questions on 5 management functions of the Primary Health Care Performance Initiative: leadership, information system, financial control, transfer of management and leadership skills to health facilities, and supervision. An expert panel designated management practices as "good" or "less effective." The outcome, PHC service performance, was the percentage of CLAS comanaged facilities in each DIRESA achieving coverage and utilization goals. We correlated frequency of good management practices with PHC service performance. DIRESAs were divided into Group 1, "higher performance," and Group 2, "lower performance," to identify specific practices linked to better performance. We identified 32 good management practices among 52 response options to 17 questions. Correlation between good management practice and good service performance was significant (r=.7266; 12 df; P<.01). An average of 91.1% and 37.6% of CLAS facilities achieved service goals in Groups 1 and 2, respectively. Of all good management practices identified, an average of 40.6% and 24.0% were used by Groups 1 and 2, respectively. Group 1 used 11 specific good practices more frequently than Group 2. Regional management and community-comanaged PHC services designed with accountability mechanisms should be intentionally aligned, incorporating these into policies, budgets, processes, and capacities to strengthen PHC services.

Centrifuge model tests on vertical stress distribution of geosynthetics reinforced soil (GRS) abutment

Geosynthetics reinforced soil (GRS) abutment has been widely used in the construction of small to medium single-span bridges and shows good service performance in engineering projects. Vertical stress distribution plays an important role for engineering design of the GRS abutments. Three centrifugal model tests of GRS abutments were carried out to investigate the vertical stress distribution underneath the centreline of beam seat, considering the setback distance (i.e., the distance from the beam seat to the inner of the facing) and beam seat width as influencing factors. Test results indicated the measured incremental vertical stresses under the beam seat increased with increasing loads uniformly and presented “larger on the upside and smaller on the downside” along the elevation. There existed the phenomenon of stress concentration near the top of the abutment and with the increasing beam seat width, the phenomenon of stress concentration presented more obvious. However, the setback distance had little effect on the vertical stress distribution. A comparison between measured and theoretical vertical stress showed that the AASHTO method provided a better prediction of the incremental vertical stress distribution than the FHWA method under the load of 200 kPa, but with the increasing loads, these two methods significantly underestimated the incremental vertical stress.

High-temperature oxidation behavior of TA15 aerospace titanium alloy at 500 °C and 800 °C

This study investigates the high-temperature oxidation behavior and performance of TA15 Ti alloy subjected to 500 and 800 °C service conditions. The oxidation process, microstructural evolution, mechanical property changes, and comprehensive performance were analyzed. At 500 °C, the alloy developed a distinctive blue-colored surface primarily composed of Ti6O, indicating a slow growth rate of the oxide layer. In contrast, the 800 °C condition led to severe oxidation with notable TiO2 and Al2O3 phases and extensive peeling of the oxidation layer. Microstructural analysis revealed that at 500 °C, there was minimal surface oxidation, and the microstructure showed a shallow heat-affected zone. At 800 °C, repeated oxidation and peeling cycles resulted in grain growth and a significant decrease in the β-phase proportion. Mechanical property assessments indicated an increase in micro Vickers hardness at both temperatures, with the 800 °C sample exhibiting higher values. However, tensile strength decreased significantly at 800 °C due to the severe oxidation layer peeling, reducing the effective thickness during tensile testing. In summary, TA15 demonstrated good high-temperature service performance at 500 °C, while at 800 °C, severe oxidation and peeling adversely affected the overall performance. This research provides insights into the differential high-temperature behavior of TA15, crucial for applications in elevated temperature environments.

Heterostructure Engineering of NiCo-LDHs for Enhanced Energy Storage Performance in Aqueous Zinc-Ion Batteries.

Aqueous zinc-ion batteries (AZIBs) are considered a promising device for next-generation energy storage due to their high safety and low cost. However, developing high-performance cathodes that can be matched with zinc metal anodes remains a challenge in unlocking the full potential of AZIBs. In this study, a typical transition metal layered double hydroxides (NiCo-LDHs) can be in situ reconstructed to NiCo-LDHs/Ni(Co)OOH heterostructure using an electrochemical cycling activation (ECA) method, serving as a novel cathode material for AZIBs. The optimized ECA-NiCo-LDHs cathode demonstrates a high capacity of 181.5 mAh g-1 at 1 A g-1 and retains 75% of initial capacity after 700 cycles at 5 A g-1. The abundant heterointerfaces of the NiCo-LDHs/Ni(Co)OOH material can activate additional active sites for zinc-ion storage and accelerate ion diffusion. Theoretical calculations also suggest the heterostructure can boost charge transfer and regulate ion-adsorption capability, thereby improving the electrochemical performance. Additionally, the flexible AZIBs device exhibits good service performance. This study on interface engineering introduces a new possibility for utilizing LDHs in AZIBs and offers a novel strategy for designing electrode materials.

A new methodology for pre-camber design of a long-span bridge considering dynamic train load and complex environmental effects

This work aims to develop a reasonable pre-camber design method for long-span cable-stayed bridges by investigating the high-speed train-bridge interaction under complex environmental loads, including ambient temperature, concrete creep, and concrete shrinkage (CCCS). First, an integrated dynamic model of the train-track-cable stayed bridge system (TTCSBS) is established using multibody dynamics and finite element theory and validated through field test. Then, the temperature change features at several key positions on the long-span bridge are investigated using long-term monitoring data. Temperature-induced bridge deformation is calculated by applying the established bridge finite element model (FEM) and compared with test results. CCCS-induced bridge deformation is determined through numerical calculations that consider the bridge's structural and material properties. On this basis, the effects of bridge deformation caused by environmental loads on vehicle-bridge dynamic interaction are investigated in detail, and a new bridge pre-camber design method is proposed to counteract the effects of both environmental and train dynamic loads. Results indicate that the proposed model's simulations align well with field test data. The long-span bridge deformation induced by the environmental loads intensifies the dynamic responses of a running vehicle, particularly the wheel-rail vertical force and car-body vertical vibration. However, it has slight influence on train-induced bridge vibration. The proposed pre-camber design method for long-span bridges, which accounts for long-term environmental load action, effectively ensures good vehicle service performance. The research results could provide useful guidance for the design of long-span bridge systems.

Self-cleaning foulant attachment on near-infrared responsive photocatalytic membrane for continuous dynamic removing antibiotics in sewage effluent environment

Bifunctional photocatalytic nanofiltration (PNF) membrane has become a reliable frontier technique for removing refractory organic micropollutants. However, the active mitigated fouling mechanism from the microscopic perspective during its long-term operation of purifying real micro-polluted water is rarely studied. Herein, with an integrated use of QSense Explorer and confocal laser scanning microscope techniques, self-cleaning foulant attachment on an activated and customized near-infrared responsive polymeric PNF (termed as nPNF) membrane with good service performance for continuous dynamic removing antibiotics in sewage effluent environment was firstly elucidated. Time-dependent changes in dissipation oscillation frequency, sensed mass and the visualized foulant spatial distribution all indicated that there were only sporadic foulant attachment, an extremely low fouling layer thickness and irreversible fouling rate on/of the activated nPNF membrane top surface, thereby endowing it with excellent self-cleaning characteristic. This is probably because the reactive oxygen species (mainly •O2− and •OH) concurrently destroys the integrity of fouling layer and its internal adhesion structure, transforming part of the irreversible fouling on nPNF membrane surface into reversible one that is easy to wash off. These new horizons provided useful insight on the fate of selected antibiotics in the to-be-removed stage and self-cleaning foulant attachment of PNF membrane.

Mud pumping in high-speed railway: in-situ soil core test and full-scale model testing

Mud pumping induced by moving train loads on rainwater-intruded roadbed causes intensive track vibrations and threatens safety of high-speed trains. In this paper, a vehicle–track–subgrade finite element model was established to analyze the dynamic responses of a ballastless track, and results showed that the concrete base and roadbed were detached because of the whipping effect arising from the rainwater intrusion channel. An in-situ soil core test showed that the intruded rainwater accumulated in roadbed to form standing water and saturated the roadbed. The flapping action of the concrete base caused by the whipping effect led to mud formation mixed with fine particles and rainwater, which migrated upward under the pore-water pressure (PWP) gradient. Mud pumping resulted from continuous particle migration in the saturated roadbed under moving train loads: under normal roadbed condition, coarse and fine particles were uniformly distributed in the roadbed; in early period of mud pumping, fine particles migrated downward to bottom of the roadbed because of the rainwater infiltration flow; in middle stage of mud pumping, fine particles migrated upward and gathered at the roadbed surface under PWP gradient; in later period of mud pumping, fine particles were entrained and removed with the dissipation of excess PWP. Moreover, a full-scale physical model was established to reproduce mud pumping, and polyurethane injection remediation against mud pumping was validated on this physical model. The remediation method was applied to an in-situ mud pumping. The deviation of the vertical track profile reduced remarkably and remained at a low level within half a year, showing a good long-term service performance of the polyurethane remediated roadbed.

Telecom Big Data Based User Offloading Self-Optimisation in Heterogeneous Relay Cellular Systems

This paper proposes a telecom big data based user offloading self-optimisation (TBDUOS) scheme. Its aim is to assist telecom operators to effectively balancing the load distribution with achieving good service performance and customer management in heterogeneous relay cellular systems. To achieve these objectives, in the cell-level offloaded traffic analysis stage, the optimal offloaded traffic is calculated to minimise the total blocking probability. In the user-level offloading stage, the user portrait is drawn and the K-MEANS algorithm is employed to manage the users clustering in the heavily loaded cell, and finally shifting users to assistant cells. Simulation results show the TBDUOS scheme can effectively reduce the handover failure and call dropping of specific users, especially voice/stream users, high consumption users, high level users. The TBDUOS scheme can also reduce the blocking probability.

The Effect of Microstructure Inhomogeneity on Fatigue Property of EA4T Axle Steel

Axles are the key component of high‐speed rail trains, which are required to have a good service performance. In the current study, the microstructures, basic mechanical properties, and fatigue property of EA4T axle steel are investigated. Due to the temperature gradient during heat treatment, the industrial EA4T axles present differences in microstructures, basic mechanical properties, and fatigue property along the radial direction. It is found that the difference in fatigue properties for the outer and middle layers results from the microstructures inhomogeneity variations, and the difference in fatigue properties can be evaluated more accurately by the statistical results of microhardness. The effect of the microhardness evaluation method is that the fatigue characteristic ratios for the two layers calculated by microhardness are more similar than fatigue ratios calculated by tensile strength.

A Conductive Bamboo Fabric with Controllable Resistance for Tailoring Wearable Sensors.

Force-sensitive textile sensors are becoming a research hotspot as a part of wearable devices. The core research topic is the method to obtain the sensing property, which decides the sensitivity and service performance of the sensors. Here, we introduce a new sensing mechanism based on a statistical change of contact resistance that exhibits an exponential decay upon strain or pressure, where a novel conductive bamboo fabric is prepared and the dependence of electric conductivity on the fabric structure is discovered. The fabric surface resistivity (ρs) is anisotropic with respect to the measuring directions and the warp, weft, and linear densities. The surface resistance (Rs) decreases rapidly under pulling force, especially in diagonal directions, making it available in designing strain sensors. The volume resistivity (ρv) decreases with increasing weft and linear densities, too. The vertical resistance (Rv) decays exponentially under pressure, and the rule is retained even if the fabric is coated with a polymer, leading to diverse possible pressure sensors with a good service performance (e.g., waterproof). Finally, the conductive fabric could be facilely tailored to various wearable sensors with a fast response time, e.g., sensing finger sleeves and sensing insole, which could be used to operate the manipulator's fingers or to monitor human walking gestures, respectively.

The perception of the farmer on dairy cooperative feed mill logistics service using customer satisfaction index (CSI) and importance-performance analysis (IPA)

A good logistics service performance in the dairy feed mill increases farmer benefits and reduces negative environmental effect. Therefore, this study aims to measure the effectiveness of logistics services quality in dairy cooperative feed mill using the customer satisfaction index (CSI) method and important performance analysis (IPA) to enhance performance quality in achieving sustainable business processes. This was conducted in Lembang Districts, West Java, Indonesia, with 150 farmer members of the cooperative as respondents. Then, a total of 100 questionnaires that is suitable with the analysis criteria were used. The CSI method was used to determine farmers’ perception of the logistics service performance and the IPA was adopted for selecting the attributes that need improvement. The result showed a CSI value of 71.05%, which falls under the satisfied category and the IPA diagram showed that the responding rate toward farmers’ demand and employees’ willingness to help was in quadrant II. Conclusively, the logistics service in the cooperative is effective to fulfil farmer needs. Furthermore, some attributes in quadrant II are useful recommendations for improving the logistics service quality.

Surface integrity of heat treatable magnesium alloy AZ80A after cavitation peening

The present paper aims to investigate topographical behavior of precipitation hardened magnesium alloy AZ80A subjected to cavitation peening. The introduction of surface residual compressive stress is the main feature of this new method, which is different from the traditional mechanical processing method and is also the key factor leading to the good service performance of the metal material surface. The tested material was heat treatable magnesium alloy AZ80A. Magnesium alloys have the lowest density among the common non-ferrous alloys and so are very important in reducing the weight and are used in many fields, including aviation, aerospace, electronics and automobile industries. After heat treatment of the magnesium alloy, cavitation peening was performed, which in all cases raises the surface hardness of the specimens. Cavitation peening also has a beneficial effect on compressive residual stresses, as they increase in all cases. It should be noted that in all specimens throughout the entire measurement depth the residual stresses stayed in compressive nature. They are especially expressed in the case of artificial aging, where we also achieve the maximum stress on the specimen surface in the amount of −220 MPa. The most negative thing about such a process is the surface roughness after cavitation hardening as it is greatly increased in all cases.
