Microgrids have emerged as a feasible solution for consumers, comprising Distributed Energy Resources (DERs) and local loads within a smaller geographical area. They are capable of operating either autonomously or in coordination with the main power grid. As compared to Alternating Current (AC) microgrid, Direct Current (DC) microgrid helps with grid modernisation, which enhances the integration of Distributed and Renewable energy sources, which promotes energy efficiency and reduces losses. The integration of energy storage systems (ESS) into microgrids has garnered significant attention due to the capability of ESS to store energy during periods of low demand and then provide it during periods of high demand. This research includes planning, operation, control, and protection of the DC microgrid. At the beginning of the chapter, a quick explanation of DC microgrids and their advantages over AC microgrids is provided, along with a thorough evaluation of the various concerns, control techniques, challenges, solutions, applications, and overall management prospects associated with this integration. Additionally, this study provides an analysis of future trends and real-time applications, which significantly contributes to the development of a cost-effective and durable energy storage system architecture with an extended lifespan for renewable microgrids. Therefore, providing a summary of the anticipated findings of this scholarly paper contributes to the advancement of a techno-economic and efficient integration of ESS with a prolonged lifespan for the use of green microgrids.

Published: October 2023

In Argentina, the excessive use of fertilizers is common in intensively cultivated zones around highly populated areas. Bioinoculants based on plant growth promoting rhizobacteria (PGPR) could be effective for crop production improvement without negative effects on the environment. The objective of this work was to evaluate an alternative inoculation method, namely the application of the biofilm produced by Bacillus subtilis as a growth promoter on seeds of three varieties of Lactuca sativa, and to compare it with the common planktonic approach. Biofilm was obtained under static culture conditions, while planktonic inoculum was produced at 150 rpm. The major biofilm effects were observed with Bacillus subtilis subsp. spizizenii, that showed antifungal activity against phytopathogens, synthesized plant growth regulators (IAA, cytokinin and ABA) and solubilized phosphates. The Grand Rapid variety inoculated with biofilm showed the best results, with 30% and 37% higher aerial and root biomass, respectively, compared to the planktonic form. Moreover, the biofilm positive effects were observed through successive plant development stages until harvest, when the bacterium was recovered from the interior of the roots. The biofilm of B. subtilis subsp. spizizenii behave as a superior growth-promoting inoculant compared to the traditional planktonic inoculation technique.
Evaluation of Carbon Emission Factors in the Cement Industry: An Emerging Economy Context
Authors: Khaiyum Mohammad Zahirul , Sarker Sudipa , Kabir Golam
Published: October 2023

The cement industry is a major contributor to carbon emissions, responsible for 5–8% of global emissions. This industry is expanding, particularly in emerging economies, and it is expected that CO2 emissions will rise by 4% by 2050. To address this critical concern, this paper identifies ten factors that contribute to carbon emissions in the cement production process through an extensive literature review and prioritises these factors using the Bayesian best–worst method. The data was gathered by conducting a methodical online survey with seven cement industry professionals in Bangladesh, with the aim of gaining insights into the emerging economy. The results illustrate that fuel burning and electricity consumption are the two greatest contributors to CO2 emissions in the cement production process. This research provides guidelines for cement industries in emerging economies on how to reduce CO2 emissions as well as suggesting areas of future research for sustainable cement production.
Application of Gated Recurrent Unit Neural Network for Flood Extraction from Synthetic Aperture Radar Time Series

Published: October 2023

Floods are a sudden and influential natural disaster, and synthetic aperture radar (SAR) can image the Earth’s surface almost independently of time and weather conditions, making it particularly suitable for extracting flood ranges in time. Platforms such as Google Earth Engine (GEE) can provide a large amount of SAR data and preprocess it, providing powerful assistance for real-time flood monitoring and time series analysis. However, the application of long-term series data combined with recurrent neural networks (RNNs) to monitor floods has been lacking in current research, and the accuracy of flood extraction in open water surfaces remains unsatisfactory. In this study, we proposed a new method of near real-time flood monitoring with a higher accuracy. The method utilizes SAR image time series to establish a gated recurrent unit (GRU) neural network model. This model was used to predict normal flood-free surface conditions. Flood extraction was achieved by comparing and analyzing the actual flood surface conditions with the predicted conditions, using a parameter called Scores. Our method demonstrated significant improvements in accuracy compared to existing algorithms like the OTSU algorithm, Sentinel-1 Dual Polarized Water Index (SDWI) algorithm, and Z-score algorithm. The overall accuracy of our method was 99.20%, which outperformed the Copernicus Emergency Management Service (EMS) map. Importantly, our method exhibited high stability as it allowed for fluctuation within the normal range, enabling the extraction of the complete flood range, especially in open water surfaces. The stability of our method makes it suitable for the flood monitoring of future open-access SAR data, including data from future Sentinel-1 missions.

Published: October 2023

During the operation of cooling water pumps, it is necessary to operate them under conditions of low flow rate. In order to improve the unstable performance of the cooling water pump under low flow rate conditions. Taking the cooling water pump as the research object, the internal flow and pressure pulsation characteristics of the cooling water pump under 0.4Q to 0.6Q conditions were investigated, and the influence of different operating conditions on the performance and vibration of the cooling water pump was analyzed. The ANSYS CFX 2022 software and the SST k-ω turbulence model were used to perform a three-dimensional numerical simulation of the cooling water pump. After analyzing the simulation results, the velocity and pressure cloud and streamline diagram within the semi-spiral suction casing and impeller were obtained. The internal flow state of the cooling water pump was then analyzed in detail under low flow rate conditions. At the same time, a series of monitoring points were set up within the impeller, and the pressure pulsation within the impeller was analyzed using the frequency domain diagram and the radial force polar coordinate diagram. The results show that at flow rates between 0.4Q and 0.6Q, a certain amount of vortex has been generated in the suction casing, which affects the flow state when entering the impeller. Furthermore, significant vortices have been generated in the middle and back part of the blade and mainly concentrated in the pump cover of the mid-open pump. At the same time, when in low flow rate conditions, the primary frequency of pressure pulsation is mainly the axial frequency, with three times the axial frequency and blade frequency following. The amplitude of the pressure surface (PS) of the blade is greater than that of the suction surface (SS) and increases as the flow rate decreases. The internal radial force corresponds with the result of pressure pulsation and exhibits a certain pattern. This study outlines the coolant pump’s internal flow and pressure pulsation characteristics under low-flow conditions. It proposes a solution to stabilize the cooling water pump at low flow rates and provides theoretical guidance for optimizing its design.
Towards a Cleaner Textile Industry: Using ASEC to Decrease the Water Footprint to Zero Liquid Discharge

Published: October 2023

Textile manufacturing is the second most polluting industry. It involves a series of processes that require large amounts of water and generates highly polluting wastewater. Four liquid wastes collected at different steps from two different textile factories (synthetic and natural fibers) were treated using a new disruptive technology (Adiabatic Sonic Evaporation and Crystallization—ASEC). After the treatment of the contaminated fluids, the byproducts obtained (freshwater and crystallized solids <1% humidity) were characterized to determine depuration efficiency and their potential commercial reuse. The physicochemical parameters were analyzed in the liquid and solid phases. The results evidence a completely efficient separation of the contaminants and solutes from the liquids analyzed, resulting in 100% pure water with the characteristics of distilled water (an electrical conductivity below 20 µS/cm) suitable for other industrial processes or water reuses, including human consumption. This implies an estimated annual reduction in the water consumption of these factories of between 16 and 103 Olympic pools. It would also avoid the disposal of 181 and 966 ton/y dried residue by the current synthetic and natural fiber textile processing factories, respectively. More than 75% of the resulting solid residue was S from the synthetic fiber industry, and light elements from the natural fiber residues. The installation of ASEC technology in different phases or at the end of industrial textile processing lines could change the paradigm of water consumption to a minimum, thus reducing consumption and resulting in the complete recycling of water. Using renewable energy and residual heat transforms the system into a zero-pollution technology; it makes it possible to attain almost 0% CO2 emissions, fulfilling the European Green Deal objectives such as a circular economy, the decarbonization of the textile industry, the protection of the biodiversity of river basins, and zero pollution.

Authors: Zhang Man , Sun Yong , Xun Bin , Liu Baoyin
Published: October 2023

Pollutant types are increasing along with the rapid development of society and economy. Some emerging pollutants from chemicals have begun to appear and endanger public and ecosystem health. However, the research and development of emerging pollutant monitoring technology is still in its infancy, with no complete monitoring system in place. This makes it impossible to access and identify the spatial pattern of emerging pollutants. Therefore, this paper reviews the existing quantitative research results on four common emerging pollutants in China’s water environment—namely, endocrine disruptors, brominated flame retardants, perfluorinated compounds, and microplastics—extracts the quantitative monitoring results of emerging pollutants in the case studies, and outlines the spatial distribution characteristics of emerging pollutants in the water environment. The results show that the emerging pollutants have a large distribution area that has covered most of China. The level of pollution from emerging pollutants correlates with the level of economic development and the pollution level in economically developed regions such as the Yangtze River Delta, the Pearl River Delta, and the Beijing–Tianjin–Hebei region is significantly higher than in other regions. This study provides a reference for the prevention and control of emerging pollutants in China.

The Impact of 2022 Capital and Currency Restrictions on the Fulfillment of the Covered Interest Rate Parity
Authors: Zubarev A. V. , Motyakina Ya. P.
Published: October 2023

This paper examines the fulfillment of the covered interest rate parity on Russian data from 2021 to 2023. The fulfillment of the covered interest parity means that investors are not able to profit from currency arbitrage using forward contracts. Crisis periods and restrictions on capital flows can clearly lead to non-fulfillment of interest parity.

The purpose of this work is to study the dynamics of deviation from covered interest parity for three-month and six-month deposits for two currency pairs (USD/RUB and CNY/RUB) in the period before and after the introduction of sanctions in 2022 when the Russian economy faced significant shocks and restrictions on capital flows. In this work, the authors study the two currency pairs, one of which is subject to significant currency restrictions, and the other is free to exchange. In this paper, the authors use standard methods: graphical and econometric analysis; their use in such an acute period, previously unexplored in the scientific literature, determines the novelty of the work.

As a result, the study revealed that since March 2022, the covered parity of interest rates has ceased to be fulfilled; the peak values of the deviation occurred in May and June 2022. By the beginning of 2023, the situation had stabilized, and the deviation from parity had decreased. Since March 2022, the ruble has lost its investment appeal, as amid overvalued exchange rates, expectations of the ruble weakening in the foreseeable future were included in forward contracts. Therefore, it was much more profitable to keep savings in foreign currency.
Additive Metric Composition-Based Load Aware Reliable Routing Protocol for Improving the Quality of Service in Industrial Internet of Things
Authors: Dharmalingaswamy Anitha , Pitchai Latha
Published: October 2023

The Internet of Things (IoT) is the collection of low-power devices deployed in real-time applications like industries, health care and agriculture. The real-time applications must quickly sense, analyze and react to the data within a time frame. So the data’s should be transmitted without any delay. The Routing Protocol for Low-power and Lossy Networks (RPL) is used to route the data by finding the optimal path. RPL forward the data packets from source to destination based on the objective functions. The objective functions can be designed using different routing metrics and most of the existing objective functions are not designed based on the characteristics of IoT applications. The Industrial Internet of Things (IIoT) environment with real-time data transfer characteristic is considered for this proposed work. Packet loss, power depletion and load balancing are the problems faced by real-time environment. Neighbor Indexed based RPL (NI-RPL) is implemented in two steps to improve efficiency of RPL. First, based on the Received Signal Strength Indicator (RSSI) and path-cost the preferred-parent set is formed from the set of neighboring nodes. Second, the rank of the nodes from the preferred-parent set is calculated based on the Neighbor Index (NI), Expected Transmission count (ETX) and Residual Energy (RE), and then the best route is selected based on the rank. The NI is used to avoid congestion, the ETX and RE helps in improving the Quality of Service (QoS) and lifetime of the network. The proposed objective function, NI-RPL is compared with other objective functions. NI-RPL guarantees the delivery of real –time data with better QoS, because it has improved the packet delivery ratio by 3% to 5% and decreases latency by 7 to 12 seconds
Quelques toponymes issus de la petite végétation arbustive en Champagne-Ardenne (suite) : le buis

Après deux articles consacrés à la descendance toponymique de racines à valeur collective (* bruscia "excroissances", dans la NRO 57 et * haisi "broussailles, buissons" dans la NRO 58), nous proposons une étude des toponymes liés à une essence précise, le buis. Ce végétal se caractérise du point de vue linguistique par d’importantes distorsions entre les plans dialectologique et toponymique, mais aussi, sur ce dernier, par une représentation beaucoup plus abondante des dérivés que du mot simple. Par ailleurs, cette recherche conduite à travers les corpus cadastraux s’inscrit dans une démarche pluridisciplinaire et s’articule avec une investigation conduite à l’échelle nationale à partir de la base de données toponymiques de l’IGN.
The Barocci systems: news (and questions) about Greek (and Latin) ruling

Published: October 2023

Dans deux manuscrits grecs, réglés à la pointe sèche, se trouve un ensemble de quatre systèmes de réglure (surnommés «systèmes Barocci » ), dont deux ressemblent à ceux qui ont été désignés comme Leroy 9 et 10, les deux autres étant sans parallèles connus. L’étude des «empreintes digitales » (petites irrégularités qui montrent quelle impression indirecte correspond à quelle impression directe) prouve que les systèmes ressemblant à des systèmes Leroy ne peuvent avoir été réalisés selon la méthode la plus probable utilisée pour tracer ceux-ci. Il en ressort l’évidence que le diagramme du système superficiel n’est pas suffisant pour comprendre la réglure : il faut étudier le «système approfondi » . — Une méthode a été proposée pour réaliser concrètement des cahiers Barocci, mais nous sommes encore loin d’être certains que ce soit la vraie solution. D’autres systèmes sont exposés, quelques uns purement théoriques, d’autres bien réels, comme un groupe trouvé par J.-H. Sautel.

Published: October 2023

This paper suggests that the second, third and fourth fascicles of Manuscript 10131 from the National Library of Spain were copied at a later stage than the first and fifth ones. Codicological and textual evidence is provided to support this claim. A codicological analysis shows that earlier and later parchments are of different type. Textual evidence is found in information included in the proem and index of the manuscript as well as in an abrupt beginning of the work. This is suggestive of textual amendments made on some fascicles. Importantly, after assembling the fourth fascicle — which was amended — and the fifth one, no information was lost and no differences in handwriting have been identified. Thus there are no textual indicators of amendment in the transition between the two fascicles. Amendments of this type required careful and tactful treatment. For this reason, only the most dexterous copiers got involved, using different techniques to do their work.

Розглянуто кілька задач побудови інтелектуальних систем керування, які включають задачу побудови адаптивної системи керування, що містить лінійний скалярний динамічний об’єкт за наявності довільних обмежених невимірюваних збурень з невідомими межами (задача 1); задачу навчання керуванню лінійним багатозв’язним статичним об’єктом в режимі off-line (задача 2); задачу побудови системи керування нелінійним багатозв’язним статичним об’єктом на базі його нейромережевої моделі (задача 3); задачу побудови системи керування тим же об’єктом на базі асоціативної моделі (задача 4) та задачу навчання розпізнаванню ситуацій керування, яка виникає за наявності скінченної множини допустимих керувальних дій (задача 5). Відмінна особливість задачі 1 — відсутність будь-якого припущення про наявну апріорну інформацію щодо меж множини належності вектора невідомих параметрів об’єкта. Для розв’язання даної задачі розроблено і детально обґрунтовано метод множинного оцінювання, що має бути реалізовано на додаток до традиційного методу точкового оцінювання цього вектора. Новизна даного методу полягає у тому, що замість невідомої апріорної множини належності вектора параметрів об’єкта слід будувати та оновлювати його своєрідну апостеріорну множину належності, використовуючи сигнали, доступні до вимірювання. Аби розв’язати задачу 2, запропоновано залучення досвідченої людини-оператора як зовнішнього «вчителя» для навчання моделі об’єкта в режимі off-line і одночасно — для керування об’єктом доти, доки цей режим не завершиться. У рамках розв’язання задачі 3 запропоновано застосування оберненої нейромережевої моделі, що має безпосередньо навчатися у ланцюгу керування та формувати керувальні дії. Наведено деякий алгоритм, орієнтований на розв’язання задачі 4. Аби розв’язати задачу 5, висунуто новий метод навчання розпізнаванню ситуацій керування, названий методом «найближчого сусіда».
Aerosol Typology and Trajectories in the Metropolitan Region of Rio De Janeiro, Brazil

Published: October 2023

Aerosols are liquid or solid particles suspended in the atmosphere. Correct determination of the distribution of aerosol types in the atmosphere is of paramount importance for long-term climate predictions. The latest report of the International Panel on Climate Change (IPCC) addresses aerosols as representing the most significant uncertainties in the context of forcing climate sources. These particles can interfere with the climate directly, indirectly, or semi-directly. Directly, we can highlight the interaction of these particles with solar radiation through their scattering or absorption. Indirectly, the role of these aerosols as nuclei for the condensation of liquid and ice in clouds is significant. Depending on their quantity, these aerosols can form larger or smaller droplets, leading to changes in the cloud's albedo. As for semi-direct effects, we can emphasize the role of aerosols as radiation absorbers within clouds, consequently leading to changes in the stability of the air parcel. As a semi-direct effect, we can highlight changes in the life cycle and the ability to make convective clouds colder and more profound.

Published: October 2023

Hotel adalah bentuk akomodasi yang dikelola secara komersial, disediakan bagi semua orang untuk mendapatkan layanan dan penginapan termasuk untuk makan dan minum. Tujuan pembuatan aplikasi ini adalah untuk memudahkan para konsumen guna mendapatkan/memesan hotel secara mudah dengan menggunakan aplikasi. Sistem pendukung keputusan dapat merekomendasikan kepada calon pelanggan untuk menentukan hotel pilihan secara cepat, tepat, dan akurat. Dalam aplikasi ini, dirancang sistem berbasis web yang menggunakan bahasa pemograman  PHP  berdasarkan  database  MariaDB.  Aplikasi    ini  juga  hanya  melakukan pencarian  hotel  di  Depok dan  mencari  hotel  terdekat  berdasarkan  jarak,  harga,  dan  rating berdasarkan tempat kita berada, yaitu di daerah Kota Depok. Sistem dikembangkan dengan menggunakan algoritma KNearest Neighbor (K-NN). Metode ini dipilih karena metode K- Nearest Neighbor adalah bentuk model pendukung keputusan yang dapat mengklasifikasikan data berdasarkan jarak terdekat. K-Nearest Neighbor adalah formula paling sederhana yang sering   digunakan   untuk   mengimplementasikan   pencarian   jarak   jauh.   Hasil   penelitian menunjukan bahwa Metode K-NN (K-Nearest Neighbor) dapat diterapkan dengan rumus Euclidean Distance untuk perancangan aplikasi sistem pencarian hotel yang menggunakan K- Nearest  Neighbor  dengan  menerapkan  kriteria  seperti  alamat  dari  pelanggan,  harga,  dan peringkat yang ditentukan sehingga dapat diimplementasikan sebagai media rekomendasi untuk pencarian  hotel.  Semakin  banyak data  training  hotel  yang di-input  dan digunakan,  tingkat keakuratan akan semakin baik dan tepat.

Authors: Suryani Anny
Published: October 2023

Penelitian ini bertujuan menentukan model matematis penduduk miskin di kabupaten/kota Jawa Barat yang dipengaruhi oleh faktor pendapatan per kapita, indeks pembangunan manusia, tingkat kepadatan penduduk, tingkat pengangguran terbuka, dan faktor-faktor apa saja yang signifikan memengaruhi penduduk miskin tersebut. Data sekunder yang digunakan sebagai variabel-variabel diperoleh dari BPS dalam periode 2017-2018. Karena berupa data time series dan cross section, teknik analisis yang digunakan adalah regresi data panel dengan pendekatan Fixed Effect Model (FEM). Hasil analisis menunjukkan bahwa model penduduk miskin di Jawa Barat dipengaruhi secara kuat dan signifikan oleh variabel pendapatan per kapita, indeks pembangunan manusia, tingkat kepadatan penduduk, dan tingkat pengangguran terbuka dengan nilai R-Square sebesar 0.811346. Artinya, penduduk miskin di Jawa Barat dapat dijelaskan sebesar 81,1345 % oleh keempat variabel tersebut, sedangkan hasil kajian dari faktor-faktor yang memengaruhi penduduk miskin di Jabar menunjukkan bahwa variabel pendapatan per kapita dan indeks pembangunan manusia berpengaruh negatif atau berlawanan secara signifikan terhadap penduduk miskin. Artinya, bila pendapatan per kapita maupun indeks pembangunan manusia meningkat, penduduk miskin akan berkurang. Sebaliknya, jika pendapatan per kapita, indeks pembangunan manusia menurun, penduduk miskin akan bertambah. Variabel tingkat kepadatan penduduk dan tingkat pengangguran terbuka berpengaruh searah atau mempunyai hubungan yang positif. Artinya, bila tingkat kepadatan penduduk dan tingkat pengangguran terbuka meningkat, penduduk miskin akan bertambah. Sebaliknya, tingkat kepadatan penduduk dan tingkat pengangguran terbuka menurun, penduduk miskin akan berkurang. Akan tetapi, dua variabel tersebut tidak signifikan berdasarkan hasil analisis parsial. Kata Kunci : Kemiskinan, Regresi Data Panel, Tingkat Pengangguran Terbuka

Penelitian yang membahas masalah tingkat pengangguran sudah banyak dilakukan. Namun, penelitian yang memasukkan unsur lokasi atau unsur spasial dalam pemodelan tingkat pengangguran dengan objek kota / kabupaten Jawa Barat untuk periode tahun 2017 - 2018 belum pernah dilakukan.  Untuk itu, dalam penelitian ini akan dikaji faktor-faktor yang memengaruhi tingkat pengangguran terbuka kota / kabupaten di Jawa Barat dengan memasukkan unsur lokasi atau spasial dalam pemodelannya. Data yang digunakan adalah data sekunder periode tahun 2017-2018. Variabel respon dalam penelitian ini adalah tingkat pengangguran terbuka (Y) dan peubah prediktor adalah Produk Daerah Regional Bersih (PDRB) atau X1, indeks pembangunan manusia (IPM) atau X2, jumlah penduduk miskin (JPM) atau X3, tingkat kepadatan penduduk (TKP) atau X4, upah minimum regional (UMR) atau X5, tingkat partisipasi aktif (TPAK) atau X6, inflasi atau X7, angka melek huruf (AMH) atau X8, dan persentase penduduk  yang berumur 15 tahun berdasarkan pendidikan tertinggi yang ditamatkan (PAK15BPD) atau X9. Metode yang digunakan adalah analisis deskriptif, analisis berdasarkan model regresi berganda (global), dan GWR (lokal) dengan pembobot Adaftif Kernel. Hasil menunjukkan bahwa model GWR mempunyai nilai koefisien determinasi 0,7289. Artinya, sekitar 72,93% dari variasi tingkat pengangguran terbuka dapat dijelaskan oleh peubah-peubah prediktor, sisanya 27,07% dijelaskan oleh peubah lain yang tidak dijelaskan dalam penelitian ini. Nilai koefisien determinasi regresi GWR lebih tinggi dari nilai koefisien determinasi  regresi Global yakni sebesar 30,56%. Selain itu, diperoleh 27 model GWR (lokal) sesuai dengan jumlah kota/ kabupaten di Jawa Barat.

PENERAPAN TURBOCHARGER PADA MODIFIKASI SEPEDA MOTOR INJEKSI UNTUK PENINGKATAN KELUARAN DAYA SECARA EFISIEN
Authors: Suryadi Aris , Fahmi M. Munir
Published: October 2023

Sepeda motor merupakan kendaraan yang banyak digunakan sebagai alat transportasi murah dan praktis. Kapasitas volume kerja mesin yang digunakan umumnya berkisar 110 s.d. 115 cc dengan keluaran daya 7 s.d. 11 HP. Untuk mendapatkan daya yang lebih besar, dibutuhkan kapasitas volume yang lebih besar. Pengoperasian sepeda motor yang lebih besar membutuhkan konsumsi bahan bakar yang lebih banyak bahkan untuk putaran idle. Sebagai salah satu alternatif pemecahan masalah tersebut, dilakukan penelitian penggunaan turbocharger untuk meningkatkan keluaran daya motor bakar tanpa mengubah kapasitas volume ruang bakar. Keuntungan penggunaan turbocharger adalah pengaturan tingkat kompresi dan pengaktifan yang mudah sehingga pengoperasiannya dapat disesuaikan dengan kondisi motor bakar pada variasi pembebanan. Penggunaan turbocharger diterapkan pada modifikasi sepeda motor injeksi. Hal ini memudahkan konstruksi pemasangannya karean tidak adanya karburator pada sistem saluran masuk yang akan mendapat kenaikan tekanan kompresi oleh turbocharger. Untuk mendapatkan peningkatan keluaran daya, sistem pengoperasian turbocharger akan diintegrasikan dengan sistem injeksi bahan bakar. Beberapa sensor digunakan untuk membaca kondisi pengoperasian motor bakar, seperti temperatur, putaran mesin, dan pembebanan. Pembacaan sensor melalui pengontrol dapat diprogram untuk mengatur pengondisian penyemprotan dan pengoperasian Turbocharger. Hasil dari penelitian menunjukkan, laju aliran massa Supercharger/Turbocharger ( ) yang dipergunakan dapat memenuhi laju aliran massa udara yang dibutuhkan oleh motor bakar ( ),      <     Akan tetapi, terdapat output tekanan yang masih rendah, terlihat dari peningkatan daya yang dihasilkan sebesar 2,5 %.
