Plastic-Pollution Reduction and Bio-Resources Preservation Using Green-Packaging Game Coopetition
Authors: Carfí David , Donato Alessia
Published: December 2022

In this paper, we deal with the renowned problem of plastic pollution caused by food consumption and its conservation. Specifically, we consider the producer/reseller decision problem of industrial organizations in conditions of perfect competition within small oligopoly clusters. Indeed, very often, one major sustainability problem is that the presence of direct competitors in the same market determines entrepreneurship choices which lower production costs and packaging costs at the expense of the environment and public health. For this purpose, in order to show economic scenarios in which the respect and preservation of the environment and natural resources are quantitatively compatible with profits and economic growth, we present a provisional coopetitive model of the strategic interaction of two food enterprises, in direct duopoly competition, through investments in sustainable-packaging technologies. The macroeconomic goal is to propose possible actions to reduce carbon footprints and the inflow of plastics to the marine environment, following the environmental targets established by the United Nations, also in the presence of direct perfect oligopolistic competition in the same market. From a microeconomic point of view, we assume the existence of two competitors selling a very similar type of food in the same market; therefore, within a competitive interaction, we adopt a classic “Cournot duopoly” core upon which we define a parametric game, namely, a coopetitive game, together with its possible dynamical scenarios and solutions. We should notice that beyond the parameter arising from the cooperation construct, we introduce a matrix of stochastic variables, which we can also consider as the state of the world. Moreover, we numerically examine one possible state of the world to exemplify our model proposal. We determine, analytically and graphically, the optimal investment in the cooperative strategy, the purely coopetitive solution and some super-cooperative solutions. The cooperative strategy represents the common investment chosen to acquire advanced green technologies for innovative packaging, while the fourth component of any solution in the strategy space represents the state of the world at the end of the coopetitive process in which, finally, we can see the profits and costs deriving from the adoption of the green technologies.

Published: December 2022

This paper considers a class of non-homogeneous fractional systems with harmonic terms by means of the Riemann–Liouville definition. Two different approaches are applied to obtain the dual solution of the studied class. The first approach uses the Laplace transform (LT) and the solution is given in terms of the Mittag-Leffler functions. The second approach avoids the LT and expresses the solution in terms of exponential and periodic functions which is analytic in the whole domain. The current methods determine the solution directly and efficiently. The results are applicable for other problems of higher order.

Published: December 2022

Mannosylerythritol lipids (MELs) are biosurfactants with excellent biochemical properties and a wide range of potential applications. However, most of the studies focusing on MELs high titre production have been relying in the use of vegetable oils with impact on the sustainability and process economy. Herein, we report for the first time MELs production using oils produced from microalgae. The bio-oil was extracted from Neochloris oleoabundans and evaluated for their use as sole carbon source or in a co-substrate strategy, using as an additional carbon source D-glucose, on Moesziomyces spp. cultures to support cell growth and induce the production of MELs. Both Moesziomyces antarcticus and M. aphidis were able to grow and produce MELs using algae-derived bio-oils as a carbon source. Using a medium containing as carbon sources 40 g/L of D-glucose and 20 g/L of bio-oils, Moesziomyces antarcticus and M. aphidis produced 12.47 ± 0.28 and 5.72 ± 2.32 g/L of MELs, respectively. Interestingly, there are no significant differences in productivity when using oils from microalgae or vegetable oils as carbon sources. The MELs productivities achieved were 1.78 ± 0.04 and 1.99 ± 0.12 g/L/day, respectively, for M. antarcticus fed with algae-derived or vegetable oils. These results open new perspectives for the production of MELs in systems combining different microorganisms.

Published: December 2022

Porous metal–organic framework [Zn2(ttdc)2(bpy)] (1) based on thieno [3,2-b]thiophenedicarboxylate (ttdc) was synthesized and characterized. The structure contains intersected zig-zag channels with an average aperture of 4 × 6 Å and a 49% (v/v) guest-accessible pore volume. Gas adsorption studies confirmed the microporous nature of 1 with a specific surface area (BET model) of 952 m2·g–1 and a pore volume of 0.37 cm3·g–1. Extensive CO2, N2, O2, CO, CH4, C2H2, C2H4 and C2H6 gas adsorption experiments at 273 K and 298 K were carried out, which revealed the great adsorption selectivity of C2H6 over CH4 (IAST selectivity factor 14.8 at 298 K). The sulfur-rich ligands and double framework interpenetration in 1 result in a dense decoration of the inner surface by thiophene heterocyclic moieties, which are known to be effective secondary adsorption sites for carbon dioxide. As a result, remarkable CO2 adsorption selectivities were obtained for CO2/CH4 (11.7) and CO2/N2 (27.2 for CO2:N2 = 1:1, 56.4 for CO2:N2 = 15:85 gas mixtures). The computational DFT calculations revealed the decisive role of the sulfur-containing heterocycle moieties in the adsorption of CO2 and C2H6. High CO2 adsorption selectivity values and a relatively low isosteric heat of CO2 adsorption (31.4 kJ·mol–1) make the porous material 1 a promising candidate for practical separation of biogas as well as for CO2 sequestration from flue gas or natural gas.

Published: December 2022

X-ray fluorescence computed tomography (XFCT) has attracted wide attention due to its ability to simultaneously and nondestructively obtain structural and elemental distribution information within samples. In this paper, we presented an image system based on the pinhole collimator for the polychromatic L-shell XFCT to reduce time consumption and improve the detection limit. First, the imaging system model was expressed by formulas and discretized. Then, two phantoms (A and B) were scanned by numerical simulation and Monte Carlo simulation. Both phantoms with the same diameter (10 mm) and height (10 mm) were cylinders filled with PMMA, and embedded with GNP-loaded cylinders. The phantom A was inserted by six 1.5 mm-diameter cylinders with different Au concentrations ranging from 0.2% to 1.2%. The phantom B was inserted by eight cylinders with the same Au concentration (1%), but a radius ranging from 0.1 mm to 0.8 mm. Finally, the reconstruction of the XFCT images was performed using the method with and without absorption correction, respectively. The feasibility of XFCT system presented in this paper was demonstrated by the numerical simulation and the Monte Carlo simulation. The results show that absorption attenuation can be corrected by the presented method, and the contrast to noise ratio (CNR) is proportional to Au concentration but almost remains unchanged with the radius of GNP-loaded cylinders, which may provide the necessary justification for further optimization of the imaging system.

Published: December 2022

The uneven pore water distribution in unsaturated soil will cause water movement, change the hydraulic and mechanical characteristics of soil, and then cause soil damage. Therefore, it is important to study the hydraulic characteristics of unsaturated soil. In this paper, the law of conservation of mass and Darcy’s law were used to analyze the unit soil after seepage to obtain a continuous equation. Combined with the soil-water characteristic curve (SWCC), the effect of matric suction and permeability coefficient of unsaturated soil on infiltration rate is substituted into the equation. Through the analysis of pore water stress of the unit soil, the function of the unsaturated permeability coefficient with the effective saturation degree is obtained, and the theoretical formula of the one-dimensional infiltration rate of unsaturated soil is derived. Compared with other models, this formula has fewer parameters and is easy to use.

The antibiotic azithromycin (AZM) is one of the most persistent in the environment, with potential to cause serious health and environmental problems. As some polluting discharges containing this antibiotic can reach the soil, it is clearly relevant determining the ability of soils with different characteristics to retain it. In this research, AZM adsorption and desorption were studied for a variety of soils, using batch-type experiments. The results show that, at low doses of antibiotic added (less than or equal to 50 µmol L−1), the adsorption always reached 100%, while when higher concentrations were added (between 200 and 600 µmol L−1) the highest adsorption corresponded to soils with higher pH values. Adsorption data were fitted to the Linear, Langmuir and Freundlich models, with the latter showing the best fit, in view of the determination coefficient. No desorption was detected, indicating that AZM is strongly adsorbed to the soils evaluated, suggesting that the risks of environmental problems due to this contaminant are minimized for these edaphic media. These results can be considered relevant with respect to risk assessment and possible programming of measures aimed at controlling environmental contamination by emerging contaminants, especially from the group of antibiotics, and in particular from AZM.

Published: December 2022

Since the beginning of the 21st century, agility and sustainability have played a significant role in the global manufacturing industry. The manufacturing paradigm leaning toward green procurement and organizational agility has crossed all levels of sustainability by colossally influencing the firms’ sustainable practices, innovation capacity, and eco-friendly procurements. Integrating sustainable practices in manufacturing is a complex task that demands that global economies conduct comprehensive research on the factors influencing the firms’ sustainable practices. Therefore, the study considers empirical research between organizational agility and sustainable manufacturing practices. The data was collected from 461 respondents working in the manufacturing sector by applying a convenience sampling technique. We utilized structural equation modeling (SEM) for direct and indirect hypothesis testing. The study results revealed that operational, customer, and partnering agility significantly and positively impact sustainable manufacturing practices and green procurement. Green procurement mediates the relationship between operational, customer, partnering agility and sustainable manufacturing practices. The study results showed a significant moderating role of big data between green procurement and sustainable manufacturing practices. The study findings are helpful to managers and policymakers.

In Ultimate Frisbee, players are responsible for administering and reinforcing adherence to the rules of the game. As a self-refereed sport, UF relies upon the Spirit of the Game (SOTG). This study aimed to profile the experience, to ascertain the training history of the sport, the participation and goal orientations of international Ultimate Frisbee players in the European Beach Ultimate Championship, and to evaluate the contribution of these variables in a discriminant function to classify players according to SOTG level and competitive level. The sample consisted of 160 players [females 33.8% (29.3 ± 7.2 years); males 66.2% (37.6 ± 9.7 years)] who competed in the European Beach Ultimate Championship, 2019. Factorial ANOVA was used to test the effect of sex, competitive level and SOTG level (measured by the sum of the scores obtained in five questions addressing the following domains: (1) Knowledge and use of the rules; (2) Fouls and body contact; (3) Fair-mindedness; (4) Positive attitude and self-control; (5) Communication. The results revealed that sex was not a consistent source of SOTG level variation among players. In each competitive level, those with high SOTG levels obtained lower European Beach Ultimate Championship classification (t = 5.73 to 6.55, p < 0.001, d = 1.28 to 2.06), higher SOTG classification (t = −13.21 to −7.04, p < 0.001, d = 1.28 to 2.85), and better evaluation for fouls and body contact (t = 2.76 to 9.23, p < 0.05, d = 0.86 to 1.99) and for positive attitude (t = 5.88 to 7.43, p < 0.001, d = 2.06 to 2.57), than regular SOTG level players. Players of different competitive levels demonstrated similar SOTG results. These findings provide important information to coaches, physical education teachers and sport consultants.

Published: December 2022

Stimulants belonging to the amphetamine group nowadays pose an undeniable worldwide threat to the life and health of users. Intoxications of domestic animals also occur, which can either be accidental or related to intentional human action. This study presents the first ever reported case of a simultaneous amphetamine and methamphetamine intoxication of a cat, along with the results of toxicological studies. Blood, urine, vitreous humor and liver were collected during the cat’s autopsy and analyzed by UHPLC─QqQ─MS/MS. The sample preparation technique was based on one-step precipitation of proteins with cold acetonitrile. The determined amphetamine concentrations in the collected biological materials were 93.4 ng/mL in blood, 496.6 ng/mL in urine, 589.2 ng/mL in the vitreous humor and 291.2 ng/g in liver, respectively. Methamphetamine concentrations were 45.5 ng/mL in blood, 263.1 ng/mL in urine, 351.2 ng/mL in vitreous humor, and 97.7 ng/g in liver. Other substances were also found in the biological material, i.e., diazepam, oxazepam and nordiazepam. Cases of intentional or accidental poisoning of pets with psychoactive substances are a serious problem, carrying the risk to the health and life of the animal. Therefore, it is important to increase awareness of the high risk of poisoning of domestic animals, as well as to learn about the incompletely understood mechanisms of pharmacokinetics of various drugs in animals, including cats.
Alman Oryantalizminde Temel Kıraat Problemlerine Yaklaşımlar: Geschichte des Qorâns Örneği
Authors: YILDIRIM Müslüm
Published: December 2022

Bu makalede ünlü şarkiyatçı Theodor Nöldeke (1836-1930) tarafından ilk olarak 1860 yılında Almanca olarak kaleme alınan ve daha sonraki yıllarda farklı yazarlar tarafından genişletilerek yeni baskısı gerçekleştirilen Geschichte des Qorâns’ın (Kur’an Tarihi) temel kıraat problemlerine yaklaşımlarına yer verilmiştir. Burada zikredeceğimiz yaklaşımlar, başta Nöldeke olmak üzere özellikle kıraatler konusunda kitaba önemli katkılar sunan Gotthelf Bergsträßer’e (1886-1933) ait yaklaşımlar olacaktır. Onun temel kıraat problemleri hakkındaki yaklaşımlarına geçmeden önce, Alman dilinde kıraatler konusunda yapılan bazı çalışmalara tarafımızdan yer verilmiştir. Söz konusu çalışmalar içerisinde önem açısından Geschichte des Qorâns’ın yeri tartışılmazdır. Özellikle kıraatler konusunda önemli çalışmalara imza atan Bergsträßer’in Geschichte des Qorâns’a katkıları göz önünde bulundurulduğunda kitabın değeri bir kat daha artmaktadır. Dolayısıyla Geschichte des Qorâns’ın kıraat konusuna yaklaşımı ve bu konuda söyledikleri önem arz etmektedir. Makalede, Geschichte des Qorans’ın temel kıraat problemlerine yaklaşımları olarak, başta kıraat-resm ilişkisi bağlamında bir kıraatin resmü’l-mushafa uygun olması meselesi üzerinde durulmuş, ayrıca kıraat-gramer ilişkisi bakımından da kıraatin Arapça gramere muvafakat etmesi konusu ele alınmıştır. Makalede sahih sened ilkesi detaylı bir şekilde ele alındığı gibi “icmâ”/“âmme” prensibi ve “ihtiyâr” kavramı üzerinde de durulmuştur. Son olarak kıraatlerin birleştirilmesi/standardizasyonu konusu işlenmiş ve kitabın kıraat problemlerine yaklaşımları hakkında genel bir değerlendirme yapılmıştır.

Authors: TAŞPINAR Kadir
Published: December 2022

Endülüs tefsir geleneğinin önemli simalarından olan İbn Atıyye (ö. 541/1147) ve İbn Cüzey (ö. 741/1340), iki asır arayla yazmış oldukları tefsirlerinin mukaddimelerinde ulûmü’l-Kur’ân’a dair birçok hususu ele almışlardır. Gerek İbn Atıyye’nin el-Muharrerü’l-vecîz’inin mukaddimesinde gerekse İbn Cüzey’in daha muhtasar tarzda kaleme aldığı et-Teshîl li-‘ulûmi’t-tenzîl’inin mukaddimesinde kıraat ilmini ilgilendiren bazı konu başlıklarının varlığı dikkat çekmektedir. Söz konusu başlıklarda Kur’ân’ın fazileti, Kur’ân’ın cem‘i ve istinsâhı, yedi harf meselesi, kıraat imamları, vakflar, isti‘âze ve besmele gibi bahisler yer almaktadır. İbn Atıyye, İbn Cüzey’den farklı olarak mukaddimesinde yedi harf meselesini ele alırken, İbn Cüzey’in ise kıraat imamları ve vakflarla ilgili müstakil başlıklara yer verdiği görülmektedir. et-Teshîl’in en önemli kaynaklarından olan el-Muharrer’in, mukaddimesinde yer alan kıraat meseleleri bağlamında et-Teshîl’e etkisi ne düzeydedir? Ele alınan kıraat konularının benzerliği ve farklılığı ne derece söz konusudur? Müfessirlerin kıraat ilmine dair hususları ele alış tarzı nasıldır? Çalışmamızda bu sorulara cevap aranmış, bahse konu mukaddimeler kıraat ilmi konuları çerçevesinde değerlendirilmeye tâbi tutulmuştur.
Safedî’nin Keşfü’l-esrâr ve Ebû Hayyân’ın el-Bahrü’l-muhît İsimli Tefsirlerindeki Kıraat Farklılıklarının Kur’ân’ın Yorumlanmasına Katkısı

Published: December 2022

Hz. Peygamber’in “yedi harf ruhsatı” olarak bilinen müsaadesine dayalı kıraat farklılıkları tamamı ile nakle dayalı bir rivâyet ilmi olarak ilm-i kıraatin ortaya çıkması ile neticelenmiştir. Memlûk dönemi, özellikle hicrî 7-10. yüzyıllar arası, tefsir, kıraat ve diğer İslâmî ilimlerin gelişimi açısından İslam tarihinin en parlak dönemlerinden biri olarak kabul edilmektedir. Nitekim Moğolların Bağdat'ı işgali ve Endülüs'ün haçlı seferlerine (Reconquista) maruz kalması nedeniyle Ebû Abdillah el-Kurtubî (ö. 671/1273) ve Ebû Hayyân el-Endülûsî (ö. 745/1344) gibi meşhur müfessirler bu dönemde Memlûk saltanatına sığınmak zorunda kalmışlardır. Ayrıca İzzeddîn b. Abdüsselâm (ö. 660/1262), İbnü'l-Müneyyir el-İskenderî (ö. 682/1284), Takiyyüddin ibn Teymiyye (ö. 728/1284), Şemsüddîn ez-Zehebî (ö. 728/1328), İbnü'l-Cezerî (ö. 833/1429) ve Celâleddîn es-Süyûtî (ö. 911/1505) gibi tefsir ve kıraat âlimlerinin tamamı Memlük saltanatının farklı şehirlerinde ikamet etmişlerdir. Bu araştırmada kıraat farklılıklarının âyetlerin yorumlanmasındaki etkisine genel bakışın yanında, özel olarak birbiri ile çağdaş iki önemli müfessirin, Safedî ve Ebû Hayyân’ın tefsirlerinde bu farklılıkları kullanış ve değerlendiriş tarzları karşılaştırılmalı olarak incelenmiştir. Bu araştırmada, her ne kadar kıraatlerin tercihi açısından farklı yaklaşımlara sahip olsalar da her iki müfessirin de kıraat farklılıklarını nahiv ilmi gibi diğer ilimlerle irtibatı içerisinde açıkladıkları ortaya konmaktadır. Makalenin özgün yönü bu iki müfessirin, kıraat farklılıklarına tefsirlerinde dönemin diğer tefsir âlimlerinden çok daha fazla yer vermiş olmalarının ortaya konmasında merkezileşmektedir.
Abbâsî İslâm Tarihyazıcılığını Edebî Eleştiri Odağında Okumak: Tayeb el-Hibri Örneği

Published: December 2022

Bu çalışma, Abbâsî İslâm tarihyazım geleneğini edebî tahlil perspektifinden ele alan Amerikalı araştırmacı Tayeb el-Hibri’nin akademik çabalarını değerlendirmeyi amaçlamaktadır. İlk bölümde Batı’da geliştirilen yazılı eserlerin doğasını ve temel formlarını ortaya çıkarmayı amaçlayan edebiyat eleştirisini İslâm tarihinin klasik kaynaklarına uygulamaya çalışan Batılı İslâm araştırmacılarının çalışmalarına kısaca temas edilmektedir. İkinci bölümde ise Hibri’nin çalışmaları hakkında kısaca bilgiler verilmekte, akabinde edebî tahlil yoluyla erken dönem Abbâsî hilafetine dair kaynaklardaki bilgilerin mahiyetine ilişkin ulaştığı sonuçlar değerlendirilmektedir. Hibri, Ortaçağ Müslüman tarihçilerin düşünce dünyasını yeniden inşa etme ve onların edebî başarılarına gereken değeri verme çabasında, hem filolojik hem de tarihsel eleştiri paradigmalarını aşan bir metodolojiye ihtiyaç duyulduğu kanaatindedir. Bu düşünce çizgisini takip ederek iki önemli başyapıtında İslâm tarihçiliğinde tarihsel gerçekliğin inşasında en temel araçlar olarak kullanılan haberi/rivayeti bir söylem olarak ele almakta, haberin/rivayetin kendisi kadar tutarlı bir anlatıya nasıl dönüştürüldüğüne ilişkin interaktif süreci irdelemeye çalışmaktadır. Ortaçağ İslâm tarihçilerini yaşadıkları dönemin toplumsal, tarihsel, ekonomik koşullarına bağlı olarak oluşturdukları tutarlı anlatılarla geçmişi yorumlamaya çalıştıklarını, bunu yaparken mecaz, kinaye, kelime oyunları ve ironi gibi bir dizi karmaşık üslup biçimlerini kullandıklarını ileri sürmektedir.

La Hidrovía Paraguay-Paraná como corpus iuris aquarum
Authors: Capaldo Griselda D.
Published: December 2022

El interés concitado por la licitación y posterior concesión de la vía fluvial Paraná, Río de la Plata, Magdalena, genera un espacio óptimo para referirnos a la hidrovía Paraguay-Paraná desde la perspectiva jurídica y, más enfáticamente, desde la triple óptica del Derecho Internacional Público, del Derecho de Aguas y del Derecho Ambiental. Esas tres ramas de la enciclopedia jurídica forman el marco teórico sobre el que descansa el presente trabajo. La perspectiva internacional se justifica porque la hidrovía Paraguay-Paraná es parte de una cuenca transfronteriza entre cinco países que, a su vez, integran el Mercosur (con Bolivia en proceso de adhesión plena). El abordaje ambiental no puede estar ausente por cuanto se trata de uno de los derechos y garantías consagrados por la Constitución Nacional de cada uno de los ribereños. El objetivo específico de esta investigación es indagar sobre el grado de coherencia y robustez de ese conjunto normativo y, en razón de ello, colegir que componen un corpus iuris aquarum aplicable a la hidrovía Paraguay-Paraná.

Published: December 2022

Las ciudades son un espacio privilegiado para la creación humana y locus de concentración de actividades sociales y económicas. Pero es también en ellas donde se producen inequívocas manifestaciones de desigualdad y exclusión social, profundizadas, especialmente en el caso de Brasil, por las malas condiciones de la movilidad urbana de los socialmente vulnerables. A partir de eso, este artículo presenta una agenda de políticas públicas que permita mejorar la movilidad urbana, teniendo como referencia los Objetivos del Desarrollo Sostenible, para las ciudades brasileñas. Esta agenda se estructura en torno al rol central del Estado en la formulación e implementación de políticas públicas; destaca la necesidad de una planificación integrada entre uso del suelo y transporte a escala metropolitana, la formación de recursos humanos para actuar en los órganos de control, el financiamiento de la investigación pública articulando universidades y organizaciones de la sociedad, el uso de plataformas digitales para la gestión integral de las redes de transporte y la información a la población y la participación social en la perspectiva de construcción de la ciudadanía.
Influência de variáveis climáticas no fluxo de ciclistas em Belo Horizonte

Published: December 2022

Muitos são os fatores que determinam a escolha de uma pessoa em utilizar ou não a bicicleta. Esses fatores podem estar relacionados às características socioeconômicas do indivíduo e às caraterísticas do ambiente, como o clima. O impacto do clima no ciclismo pode ser complexo uma vez que os fatores relacionados ao conforto podem ter um peso importante na decisão de usar a bicicleta e os ciclistas estão completamente expostos às intempéries. Diante disso, o trabalho se propôs a analisar as principais variáveis climáticas que influenciam no fluxo de ciclistas em Belo Horizonte. As variáveis testadas foram temperatura, umidade, precipitação e nebulosidade. As variáveis que apresentaram melhor resultado para explicar variabilidade no fluxo de ciclistas foram umidade e precipitação. O modelo encontrou um alto poder explicativo para a variável umidade, em que a disposição para pedalar aumenta conforme a umidade relativa do ar cresce entre 30% e 50%. O modelo também sugere que a variável chuva é significante onde para cada acréscimo de 1mm de chuva há uma queda 0,75% no número de ciclistas. Este trabalho destaca a importância de o poder público considerar as variáveis climáticas nos processos de planejamento urbano e de construção de políticas públicas de mobilidade.

Designing automatic midges for rice plants, in addition to trapping and repelling insect pests, can alsokill pests that always interfere with the growth of rice plants automatically based on microcontrollers. In thisdesign, PIR, ultrasonic sensors, and ESP32 are used as control systems. Ultrasonic sensors are used to emitultrasonic waves as a pest disruptor that wants to get close to rice plants. The PIR sensor itself is set to detectpests approaching plants and then react to the ultrasonic sensor to emit waves to disturb pests that perch on riceplants. The PIR sensor will work by capturing the thermal energy possessed by insect pests in front of the sensor. This is where the Arduino plays a role as a controller, which will carry out the execution. The use of this electric racket module is to give a sting to pests if the pests caught directly perch on the wire surrounding the lamp, where the wire has been supplied with a high electrical voltage even with a small electrical voltage input. In addition, the use of the module here is useful for killing pests that perch on traps if pests are not disturbed by waves emitted by ultrasonic sensors. The test results show that the performance of the designed system can function properly. The designed system can detect objects in the form of insect pests and can accurately display data to the 16x2 LCD.

The project development process related to scheduling and cost budgeting in the project scheduling process is often not in accordance with field conditions, causing delays in its completion. Budget costs related to progress are generally directly proportional to scheduling. The tank construction project currently underway is the Refinery Development Master Plan (RDMP) project, namely Tank Modification carried out by contractor PT XYZ. The construction of the tank that will be evaluated is the P-4 tank with a duration of 252 days. The P-4 tank is a tank that functions as a container of crude oil with a diameter of 39 meters by 12.8 meters, and has been used for approximately 30 years, so it requires rejuvenation or modification that requires special handling considering that the modification of the tank is in the middle of the area or operating refinery unit. The method in the evaluation uses work scheduling and the budget for the construction of the P4 tank. The scheduling method takes into account the factors of rainfall intensity, labor and the Critical Path Method. Meanwhile, the additional cost budget will be reviewed in the S curve (S-curve) of the project. In evaluating scheduling, the rainfall factor is the main contributor resulting in the delay of the completion schedule or work completion date as much as 16%. Based on the analysis using the Critical Path Method (CPM), the realization of the project was 22 days late from the initial planning of the work. Despite the delay in the tank construction schedule, this does not affect the budget.

UD Bangkit Tiga Brothers is one of the SMEs engaged in the furniture manufacturing industry with antique products. The problem that occurs in this company is that it cannot estimate the exact number of orders for raw materials because the number of sales varies each period. So that every time you place an order, you sometimes exaggerate the product to be used as stock and save on ordering costs in the transportation section. At a certain time when there is a demand but the stock in the warehouse runs out so you have to reorder and excess orders for stock supplies. One solution that is applied to overcome this problem is the Lot Sizing method. By applying this method, the raw material procurement system can be identified by predicting the demand for raw materials and using the Lot Sizing method in order to obtain the optimum raw material procurement. Optimul forecasting results were obtained using the Exponential Smoothing method with a MAPE of 20.34%. The forecasting value obtained is 45.62 46 pcs in August 2022 with an accuracy value of 79.66% of the results then calculated using the Lot Sizing method. The results of the calculation of the Lot Sizing method obtained the optimal method, namely the Period Order Quantity (POQ) which is Rp. 58.130.923,-. The resulting difference with the value of the company is Rp. 4,217,240, - or 6.76%. From the figures obtained, it results in cost savings that are very profitable for the company.
