In this paper, we aim to underscore the need for a more nuanced understanding of vaccine non-adopters. As the availability of vaccines does not translate into their de facto adoption—a phenomenon that may be more pronounced amid “Operation Warp Speed”—it is important for public health professionals to thoroughly understand their “customers” (i.e., end users of COVID-19 vaccines) to ensure satisfactory vaccination rates and to safeguard society at large. © 2020

IOP Conference Series: Earth and Environmental science 2019年第1期399卷

作者： I Firmansyah Widiatmaka B Pramudya S Budiharsono Study Program of Natural Resources and Environmental Management IPB University Department of Soil Science and Land Resources Faculty of Agriculture IPB University Department of Mechanical Engineering and Biosystem Faculty of Agriculture Technology IPB University Technical Advisor Ministry of National Development Planning/National Development Planning Agency (BAPPENAS)

The rate of population growth and the increase in food needs for consumption have made the need for paddy fields higher. On the other hand, the pressure on paddy fields is quite intense so that the conversion of paddy fields is quite challenging to be controlled. Moreover, the concerns about food security and food sovereignty have become critical issues. The high demand for land utilization has caused pressure on paddy fields in the Citarum watershed. The objective of this study is to build a model for maintaining paddy fields in the Citarum watershed. The study was conducted from June to September 2015. The method of this research is a modelling using system dynamics approach by simulating time series data. From the simulation, it can be concluded that the rate of conversion of paddy fields will still be high if there is no specific policy in its protection. This fact can be seen from various scenario conditions, either in existing circumstances, in the optimistic scenario, as well as in a moderate scenario. The strategy that can be done is that paddy fields should be specially protected or owned by the government to minimize the rate of conversion.

引用

IOP Conference Series: Materials science and engineering 2019年第2期662卷

作者： S L B Ginting Y R Ginting Sutono A Rakhman Computer System Study Program Faculty of Engineering and Computer Science Universitas Komputer Indonesia Jl. Dipati Ukur 112-116 Bandung 40132 Indonesia Department of Mechanical Engineering Universitas Riau Kampus Bina Widya KM 12 5 Simpang Baru Pekanbaru 28293 Indonesia

The research intends to create an application which is able to analyse sales data in a motorcycle company to predict the types of spare parts which should be stocked. This prediction is crucial since problems are often encountered while restocking. For instance, when there have been some imprecisions occurring in deciding regarding the types of spare parts to restock, the spare parts accumulate. It can cause inefficiency in terms of storage, the products quality deteriorates due to having been stored for too long, and sometimes the best-selling products are not available in the warehouse. This application is developed with Naïve Bayes Classifier (NBC) method which has a high accuracy in predicting future occurrences. This method works by calculating the probability value in each attribute class and determining the optimal probability value. From the test results, 4500 training data with 200 sample test data has 90% similarity with the results of the restock decision without application. For 500 test data, the similarity was 96%. It is proven that this method has a high accuracy so that it can help the decision makers solved the company problem in predicting the types of motorcycle parts to be restocked.

IOP Conference Series: Earth and Environmental science 2018年第1期105卷

作者： Y W Budhi M Fakhrudin N T U Culsum V Suendo F Iskandar Chemical Engineering Study Program Faculty of Industrial Technology Bandung Institute of Technology Bandung 40132 Indonesia Chemistry Study Program Faculty of Mathematic and Science Bandung Institute of Technology Bandung 40132 Indonesia Physics Study Program Faculty of Mathematic and Science Bandung Institute of Technology Bandung 40132 Indonesia

Empty fruit bunch (EFB) of palm oil, an abundant agro-waste in Indonesia, was used as raw material of Cellulose Nanocrystals (CNCs) preparation. Instead of conventional acid mineral, phosphotungstic acid (H3PW12O40, HPW) was used to hydrolyze cellulose due to recycling ability and easy handling. Before hydrolysis process, dried EFB was treated by 3% NaOH solution at 90°C for 2 hours and then bleached using 2% NaClO2 solution at 80°C for 3 hours to remove hemicellulose and lignin. Hydrolysis reaction parameters such as temperature, acid concentration, and reaction time were optimized with fixed solid-liquid ratio of 1:40. Response surface method was used for experimental design to determine the optimum condition of each parameter by using software Minitab. In this study, pulp from dried EFB produced 44.8% yield of CNCs. Dynamic Light Scattering (DLS) analysis showed that most of CNCs equivalent diameter was 140 nm. Crystallinity index was observed at 73.3% using X-ray Diffraction (XRD) analysis. Thus, a green established process for the preparation of CNCs was achieved.

作者： Ady Satria Poltak Sihombing Sawaluddin Informatics Engineering Study Program Magister Faculty of Computer Science and Information Technology University of Sumatera Utara

Load Balancing is very well applied to the distribution of internet access at any point of the Wi-Fi area so that the use of limited devices can be optimal and on target. The proper use of the Greedy Algorithms when applied to an access point device is very capable in resolving excessive loading in a single resource to take the best choice at every stage in an optimum process. Access point device is also a success factor in running the optimization of the distribution of Wi-Fi access on the Access Point is strongly influenced by the parameters set. In this research, user access factor in one very high Wi-Fi area also influences the possibility of incoming access failure. For the application of the results of this study can be utilized on all access point devices that have limits, but for speed internet access remains at the capacity provided bandwidth.

引用

Journal of Physics: Conference Series 2018年第1期1120卷

作者： D Hikmawati A R Rohmadanik A P Putra Siswanto Aminatun Physics Study Program Department of Physics Faculty of Science and Technology Universitas Airlangga Surabaya 61110 Indonesia Biomedical Engineering Study Program Department of Physics Faculty of Science and Technology Universitas Airlangga Surabaya 61110 Indonesia

Electrospinning technique is a method to produce nanofiber with high potential difference. Several main parameters in the electrospinning process are solution parameter, such as viscosity, surface tension and conductivity. Those parameters affect the morphology of nanofiber membrane produced by the electrospinning process. This study used 10% PVA in aquadest with several Aloe vera concentration (0, 2.5, 5, 7.5 and 10 % w/v). The viscosity of the solution increased when the concentration of the Aloe vera increased. SEM image of the nanofiber membrane showed that the diameter of the nanofiber increased with the increase of the Aloe vera concentration, with the highest diameter of 379.80 nm on the membrane with Aloe vera concentration of 10% w/v. The result of DSC test showed that there were shifts on the glass transition (Tg) and melting point (Tm) value along with the addition of Aloe vera in the PVA solution. This results was also emphasized with the result of FTIR test which showed the shift on the wavenumber absorbance due to the crosslinking between PVA and Aloe vera. The degradation test indicated that the presence of crosslinking could maintain the nanofiber structure, thus the membrane was not easily degraded.

引用

AIP Conference Proceedings 2018年第1期1987卷

作者： Muhammad Rafsanjani Irwan Meilano Dina Anggreni Sarsito Geodesy and Geomatics Engineering Study Program Faculty of Earth Science and Technology Bandung Institute of Technology Indonesia

The islands of Sumatra accommodate the collision of the Indies-Australian plate pressing the Eurasian plate at a speed of 5-6 cm/yr at the boundary between the plates along the west coast of Sumatra (Natawidjaja, D.H., 2007). The oblique collision between the two plates formed a subduction zone in the western part of the island of Sumatra and a number of fault segments on the island of Sumatra. Subduction zones and cesareans segments that are formed actively move so often cause earthquakes in the region. Mentawai islands are located in the westernmost part of Sumatra and belong to the subduction zone of Mentawai Segment Mentawai Islands movement can be identified using GPS observation data. The data used are GPS observation data from 2013 to 2016 coming from Sumatran GPS Array (SuGAr) Network. The data is processed using software GAMIT / GLOBK 10.6. The results of the GPS data processing will be processed to produce velocity velocities and strain values of each GPS observation station used to observe deformation activity on the Mentawai Islands. The results of GPS observation data processing showed vector movement in Mentawai Islands referenced to Sundaland Block leads to the northeast on the northern part of the Mentawai Islands, heading southwest to the southern part of the Mentawai Islands, and heading north to the central part of the Mentawai Islands. The strain obtained from data processing showed that the Mentawai Islands experienced an interseismic phase in the north, a post-seismic phase in the south and a transitional phase in the middle.
