Public transportation between the island seas is one of the economic backbones where Maluku Province is an archipelagic area. Ambon City as the capital of Maluku Province is a city with activities and interactions between communities using public transportation to support daily activities. However, due to the enactment of PSBB (Large-Scale Social Restrictions) from June 23 to November 22, 2020, the number of public transportations (Perwali No. 18) is limited, with odd-even implementations up to passenger restrictions (6 people per trip), resulting in operational costs. Vehicles will increase. This study aims to find out how much the upper and lower limit tariffs are used for the community and students. In this study, the calculation method was used according to the Standards of the Directorate General of Land Transportation (2002) SK 687/AJ.206/DRDJ/2002. The results of the study show that the upper and lower tariff rates for the community in Nusaniwe District are Rp. 16,592 – Rp. 11,061,-; Sirimau District IDR 5,138 – IDR 3,425,-; and Baguala and Teluk Ambon Districts Rp. 25,000 – Rp. 16,666,-. The upper and lower limit rates for students in Nusaniwe District are Rp. 8,296 – Rp. 5,531,-; Sirimau District IDR 2,569 – IDR 1,712,-; and Baguala and Teluk Ambon Districts Rp 12,500 – Rp 8,333,-. Tariffs based on the BOK during the PSBB period ranged from Rp. 25,000 – Rp. 5,138,-, while the real tariff was Rp. 3,000 – Rp. 5,000.

Clinical Biomarkers

Homovanillic acid (HVA) and vanillylmandelic acid (VMA) are end-stage metabolites of catecholamine and are clinical biomarkers for the diagnosis of neuroblastoma. For the first time in Korea, we implemented and validated a liquid chromatography tandem mass spectrometry (LC–MS/MS) assay to measure urinary concentrations of HVA and VMA according to Clinical and Laboratory Standards Institute guidelines. Our LC–MS/MS assay with minimal sample preparation was validated for linearity, lower limit of detection (LOD), lower limit of quantification (LLOQ), precision, accuracy, extraction recovery, carryover, matrix effect, and method comparison. A total of 1209 measurements was performed to measure HVA and VMA in spot urine between October 2019 and September 2020. The relationship between the two urinary markers, HVA and VMA, was analyzed and exhibited high agreement (89.1% agreement, kappa’s k = 0.6) and a strong correlation (Pearson’s r = 0.73). To our knowledge, this is the first study to utilize LC–MS/MS for simultaneous quantitation of spot urinary HVA and VMA and analyze the clinical application of both markers on a large scale for neuroblastoma patients.

Food Assistance Program

Because of the covid-19 virus pandemic in 2020, Indonesia is implementing large-scale social restrictions (PSBB) to protect healthy people from contracting the covid-19 virus. So most residents of Kampung Muka losing their jobs and unable to buy food for their daily needs. So they have to rely on the government’s non-cash food assistance program (BPNT). During the covid-19 pandemic occurred, the residents of Kampung Muka could not survive in their village and had to rely on government assistance to survive. The design method is the everydayness approach, by adding new daily activities in Kampung Muka, namely horticultural agriculture so that the residents can get a new source of livelihood. Also, horticultural agriculture is a source of food for residents during emergencies such as PSBB. Meanwhile, the commercial section is used as a place to sell food products and makes the view of horticultural agriculture a commercial attraction. Keywords: Commercial; Future; Government program; Horticultural agriculture Abstrak Dengan adanya pandemi virus Covid-19 pada tahun 2020, Indonesia memberlakukan pembatasan sosial berskala besar (PSBB) untuk melindungi orang yang sehat agar tidak tertular virus covid-19. Mengakibatkan kebanyakan warga Kampung Muka kehilangan pekerjaannya dan tidak dapat membeli pangan untuk kebutuhan hidup mereka sehari hari. Sehingga mereka harus bergantung pada program bantuan pangan non tunai (BPNT) pemerintah. Pada kondisi yang terjadi saat pandemi covid-19, warga Kampung Muka tidak dapat bertahan hidup di dalam kampung mereka sendiri dan harus bergantung pada bantuan pemerintah untuk bertahan hidup. Metode perancangan yang digunakan adalah pendekatan everydayness, dengan menambah aktivitas keseharian yang baru di Kampung Muka yaitu pertanian hortikultura, agar para warga mendapatkan sumber pencaharian yang baru. Selain itu, pertanian hortikultura juga sebagai sumber pangan para warga saat kondisi darurat seperti PSBB. Sedangkan bagian komersial, dimanfaatkan sebagai tempat untuk menjual hasil pangan dan menjadikan view pertanian hortikultura sebagai daya tarik komersial.

This paper presents a system in which the cluster devices are controlled by single-chip microcomputers, with emphasis on the cluster management techniques of single-chip microcomputers. Each device in a cluster is controlled by a single-chip microcomputer collecting sample data sent to and driving the device by driving data received from the same cluster management computer through COMs. The cluster management system running on the cluster management computer carries out such control as initial SCM identification, run time slice management, communication resource utilization, fault tolerance and error corrections on single-chip microcomputers. Initial SCM identification is achieved by signal responses between the single-chip microcomputers and the cluster management computer. By using the port priority and the parallelization of serial communications, the systems real-time performance is maximized. The real-time performance can be adjusted and improved by increasing or decreasing COMs and the ports linked to each COM, and the real-time performance can also be raised by configuring more cluster management computers. Fault-tolerant control occurs in the initialization phase and the operational phase. In the initialization phase, the cluster management system incorporates unidentified single-chip microcomputers into the system based on the history information recorded on external storage media. In the operational phase, if an operation error of reading and writing on a single-chip microcomputer reaches a predetermined threshold, the single-chip microcomputer is regarded as serious fault or not existing. The cluster management system maintains accuracy maintenance database on external storage medium to solve nonlinear control of specific devices and accuracy maintenance due to wear. The cluster management system uses object-oriented method to design a unified driving framework in order to enable the implementation of the cluster management system simplified, standardized and easy to transplant. The system has been applied in a large-scale simulation system of 230 single-chip microcomputers, which proves that the system is reliable, real-time and easy to maintain.

Slope Safety

Geology uncertainties and real-time construction modification induce an increase of construction risk for large-scale slope in hydraulic engineering. However, the real-time evaluation of slope safety during construction is still an unsettled issue for mapping large-scale slope hazards. In this study, the real-time safety evaluation method is proposed coupling a construction progress with numerical analysis of slope safety. New revealed geological information, excavation progress adjustment, and the support structures modification are updating into the slope safety information model-by-model restructuring. A dynamic connection mapping method between the slope restructuring model and the computable numerical model is illustrated. The numerical model can be generated rapidly and automatically in database. A real-time slope safety evaluation system is developed and its establishing method, prominent features, and application results are briefly introduced in this paper. In our system, the interpretation of potential slope risk is conducted coupling dynamic numerical forecast and monitoring data feedback. The real case study results in a comprehensive real-time safety evaluation application for large slope that illustrates the change of environmental factor and construction state over time.

This paper presents a framework which integrates maintenance and optimal operation of multiple compressors. The outcome of this framework is a multiperiod plan which provides the schedule of the operation of compressors: the schedule gives the best decisions to be taken, for example, when to carry out maintenance, which compressors to use online and how much to load them. These decisions result in the minimization of the total operational costs of the compressors while at the same time the demand of the plant is met. The suggested framework is applied to an industrial gas compressor station which encompasses large multistage centrifugal compressors operating in parallel. The optimization model of the framework consists of three main parts: the models of compressor maps, the operational aspects of compressors, and a maintenance model. The results illustrate the optimal schedule for 90 days and an example of the optimal distribution of the load of the compressors for 5 days. Finally, the results show the economical benefits from the integration of maintenance and optimization.

Abstract. Inversion of the magnetic field in a model of large-scale αΩ-dynamo with α-effect with stochastic memory is under investigation. The model allows us to reproduce the main features of the geomagnetic field reversals. It was established that the polarity intervals in the model are distributed according to the power law. Model magnetic polarity timescale is fractal. Its dimension is consistent with the dimension of the real geomagnetic polarity timescale.
