KOMPARASI SISTEM MANUFAKTUR PUSH DAN PULL MELALUI PENDEKATAN SIMULASI
Authors: Wibisono Eric 
Published: November 2023

Manufacturing systems that are often classified as push and pull often invite question: "How far do the differences between those two systems exist?" Many researches have been carried out but succinct answer to the above question is always difficult to reach. The difficulty roots from the variety of definition of the push and pull systems itself and also from the variety of complexity of a manufacturing system.
This paper attempts to study the differences in performance between push and pull systems in a relatively simple model that consists of 4 serial processors with buffers located between these processors. Variations being modelled is on the setting of the system's load (high and low) and the buffer size with performance being measured include machine utilization, number of outputs and mean flow time of jobs. The approach used is simulation using ProModel software as the tool. From the experiments it can be derived that buffer size turns out to be a very critical factor in system performance. Moreover, it is also proved that when the buffer size is large, push and pull systems do not differ significantly.

Abstract in Bahasa Indonesia :

Sistem manufaktur yang umumnya dikategorikan menjadi sistem push dan pull sering mengundang pertanyaan: "Seberapa jauh perbedaan dari kedua sistem tersebut ada?" Banyak penelitian telah dilakukan namun jawaban yang lugas atas pertanyaan tersebut sulit diperoleh. Kesulitan ini umumnya berakar dari beragamnya definisi sistem push dan pull itu sendiri serta variasi dari kompleksitas suatu sistem manufaktur.
Makalah ini mencoba melihat perbedaan antara kinerja sistem push dan pull dalam suatu model sederhana yang terdiri dari 4 prosesor serial dengan buffer yang diletakkan di antara masing-masing prosesor tersebut. Variasi yang dilakukan adalah pada setting beban kerja sistem (padat dan ringan) dan ukuran buffer dengan kinerja yang diukur adalah utilisasi mesin, jumlah output dan rata-rata waktu tinggal job. Pendekatan yang dipakai adalah simulasi dengan alat bantu software ProModel. Dari eksperimen yang dilakukan didapatkan hasil bahwa ukuran buffer sangat berpengaruh terhadap kinerja sistem. Secara khusus juga dibuktikan bahwa pada ukuran buffer besar, ternyata antara sistem push dan pull tidak memiliki perbedaan yang signifikan.

AbstractRealizing efficient electrocatalysts is a stepping stone toward achieving high‐performance alkaline water/seawater electrolysis, but remains a crucial challenge. Herein, heterogeneous Mo2N/Ni3Mo3N electrocatalysts on nickel foam (denoted MN‐NMN/NF) that is stable and active for the hydrogen evolution reaction (HER) in both alkaline water/seawater are demonstrated. The optimized MN‐NMN09/NF achieves an ultralow HER overpotential of 11 mV@10 mA cm−2 in 1.0 m KOH electrolyte, which is not only superior to the benchmark Pt/C catalysts but also the best reported ever among NiMo‐based electrocatalysts in an alkaline environment. Successively, the optimized MN‐NMN09/NF electrocatalyst can drive HER current densities of 10 and 500 mA cm−2 using low overpotentials of 9.37 and 123 mV in 1.0 m KOH seawater electrolyte, which remains durable after 120 h long‐term electrolysis at a constant current density of 500 mA cm−2. In situ Raman analysis reveals that the enhanced performance is attributed to the accelerated H2O adsorption and OH dissociation processes on the MN‐NMN surfaces. Theoretical analysis further confirms that rapid H2O adsorption‐dissociation kinetics and H adsorption‐conversion kinetics on the Ni3Mo3N/NiOOH and Ni3Mo3N/MoOx surfaces result in boosted HER capability. This work depicts a significant potential for designing stable and efficient hydrogen production electrocatalysts for both alkaline water and seawater electrolysis.

Published: November 2023

AbstractDevelopment of low‐cost electrocatalysts for water splitting is crucial to economical hydrogen production. Here, a highly efficient electrocatalyst composed of MoNi4‐embedded amorphous MoO2 nanosheets grown on less‐tortuosity hierarchically porous carbonized wood (MoNi4/MoO2@CW) is reported. The generation of abundant MoNi4/MoO2 heterointerfaces and defects‐rich MoO2 significantly promote the adsorption and activation of reactant molecules on the MoNi4/MoO2@CW. The obtained MoNi4/MoO2@CW catalyst exhibits ultralow overpotentials of 22 and 205 mV for hydrogen evolution reaction and oxygen evolution reaction at a current density of 10 mA cm−2, respectively. The catalyst can be used for dual‐function electrodes and assembling two‐electrode electrolyzer illustrates 10 mA cm−2 at 1.47 V and superior durability over 24 h for overall water electrolysis. Moreover, it also possesses a high mass activity of 142 Ag−1 MoNi4 at 200 mV, surpassing the Pt/C catalyst (132 Ag−1). The outstanding performance of the MoNi4/MoO2@CW is attributed to the decrease in energy barrier for water dissociation, optimal adsorption/desorption of H/O‐intermediates, and fast mass transport through the porous structure, as confirmed by experimental results and density functional theory‐based calculations. The MoNi4/MoO2@CW electrocatalyst has excellent potential for practical water splitting.

AbstractPrinting metallic nanoscale features remains challenging, but particularly important for making electronic devices. In existing techniques, complex operation, and material parameters significantly limit printing resolution, materials development, and real‐time control. Alternatively, aerosols and ions are synergized to print nanoscale metals, but the ions turn out to be instable, thereby making the printing lose the ability in controlling feature sizes. Herein electrically biased parallel planes are utilized to configure electric fields for programmable and parallel printing of aerosol nanoparticles into high‐purity (>98.5 wt.%) nanoscale features in arrays over large areas (≈mm2). By applying different potentials to three horizontal parallel planes, with the middle plane containing periodic circular perforations, the fields are configured into repeating “funnels” with sizes controllable at both ends. Charged nanoparticles are then subjected to a gas flow orthogonal to the field assembling them to 3D nanoarchitectures. The “funnels” size is predictable and used to control the feature sizes. The printed nanopillars are modulated from 67 to 743 nm in diameters with aspect ratios up to 25 and show excellent mechanical and electrical properties. The programmable and parallel nanoprinting of metallic nanoscale features offers an enabling technology for accelerating the development of next‐generation high‐frequency ultra‐large scale integrated electronic devices.

Published: November 2023

AbstractHighly sensitive electronic skin (e‐skin) sensors with considerable operating range offer great possibilities for health care, human–‐machine interfaces, and intelligent robotics. Although subtle microstructures have been used in recent years to improve the sensitivity and sensing range of e‐skin sensors, the trade‐off between these features remains a big challenge to overcome. Here, an asymmetric interlocked gradient elastic modulus (AIGM) structure is designed for the first time to provide sufficient deformation space to the traditional interlocked structure while ensuring high sensitivity, and the gradient elastic modulus further extends the sensing range of the AIGM structure‐based sensors, which exhibit a maximum sensitivity of as high as 9.89 kPa−1 with an ultrawide working range that extends to above 530 kPa at the same time. As a demo, this sensor is integrated into an intelligent adjustable mouse platform for physiological signal monitoring, pressure feedback, and modulus adjustment, providing a viable alternative for hand disease prevention.

Abstract2D nanomaterials are proposed as promising photothermal materials for interfacial photothermal water evaporation. However, low evaporation efficiency, the use of hazardous hydrofluoric solution, and poor stability severely limit their practical applications. Here, a mixed solvent exfoliation surface deposition (MSESD) strategy for the preparation of NiPS3 nanosheets and NiPS3/polyvinyl alcohol (PVA) converter is successfully developed. The converter is obtained by drop‐casting the NiPS3/PVA nanosheets onto a sponge. The PVA is mainly deposited on the edge of NiPS3 nanosheets, which not only improves the stability of NiPS3 nanosheets, but also adheres to the sponge to prepare a 3D photothermal converter, which shows an evaporation rate of 1.48 kg m−2 h−1 and the average photothermal conversion efficiency (PTCE) of 93.5% under a light intensity of 1 kW m−2. The photothermal conversion mechanism reveals that the energy of absorbed photons in NiPS3 nanosheets can be effectively converted into heat through non‐radiative photon transitions as well as multiple optical interactions. To the best of the knowledge, this is the first report on the application of 2D metal‐phosphorus‐chalcogen (MPChx) for solar desalination, which provides new insights and guidance for the development of high‐performance 2D photothermal materials.

AbstractThe study reports for the first time on the ultrafast dynamics of charge transfer (CT) and exciton dissociation in block copolymer PBDB‐T‐b‐PTY6‐based state‐of‐the‐art single‐material organic solar cells (SMOSCs). From the transient absorption spectroscopy of the dilute PBDB‐T‐b‐PTY6 in the insulating polystyrene, exciton dissociation and hole transfer (HT) processes at the intramolecular interface of covalent linkage between the donor and acceptor segment are achieved. In comparison to the charge generation in blend PBDB‐T:PTY6 films, it is found that the HT rate in the isolated block copolymer chain via the intramolecular channel is approximately an order of magnitude higher than that via the intermolecular channel. Much faster exciton dissociation in the dilute PBDB‐T‐b‐PTY6 film than in the blend film from electro‐absorption and polaron‐absorption signals is also verified. The intrachain chemical interface in the block copolymer is thus more conducive to the HT path than the traditional interface in the bulk heterojunction. Moreover, though the PBDB‐T‐b‐PTY6 film has weak molecular ordering, its overall CT efficiency is comparable to that of the PBDB‐T:PTY6 film. These findings portend that further molecular design with optimized ordering toward fast intramolecular exciton dissociation may contribute to SMOSCs with higher power conversion efficiency.

AbstractFerrofluidic robots with excellent deformability and controllability have been intensively studied recently. However, most of these studies are in vitro and the use of ferrofluids for in vivo medicinal applications remains a big challenge. The application of ferrofluidic robots to the body requires the solution of many key problems. In this study, biocompatibility, controllability, and tumor‐killing efficacy are considered when creating a ferrofluid‐based millirobot for in vivo tumor‐targeted therapy. For biocompatibility problems, corn oil is used specifically for the ferrofluid robot. In addition, a control system is built that enables a 3D magnetic drive to be implemented in complex biological media. Using the photothermal conversion property of 1064 nm, the ferrofluid robot can kill tumor cells in vitro; inhibit tumor volume, destroy the tumor interstitium, increase tumor cell apoptosis, and inhibit tumor cell proliferation in vivo. This study provides a reference for ferrofluid‐based millirobots to achieve targeted therapies in vivo.

AbstractThe complex pathological mechanism of Alzheimer's disease (AD) limits the efficacy of simple drug therapy, and drugs are difficult to penetrate the blood‐brain barrier (BBB). Therefore, it is a breakthrough to enhance the therapeutic effect of AD by rationally using multiple therapeutic strategies to inhibit multiple pathological targets. In this study, macrophage membrane (MM) with active targeting inflammation function is used to functionalize molybdenum disulfide quantum dots (MoS2 QDs) with the properties of elimination of reactive oxygen species (ROS) and anti‐Aβ1‐42 deposition to form the nano drug (MoS2 QDs/MM), and play the role of multi‐target combined therapy with NIR. The results show that MoS2 QDs/MM has a targeted therapeutic effect on ROS elimination and anti‐deposition of Aβ1‐42. In addition, the combined therapy group effectively reduced Aβ1‐42 mediated cytotoxicity. The modification of MM could effectively target the brain, and NIR irradiation could actively increase the cross of BBB of materials. In vivo behavioral study also show that APP/PS1 mice in the combined treatment group showed the similar exploration desire and learning ability to mice in the group of WT. MoS2 QDs/MM is an excellent nano drug with multiple effects, which has advantages in the field of neurological diseases with crisscross pathogenesis.
