Authors: Firsty Giovanni Naoki Panca Putra  , Jaswadi  , Ludfi Djajanto
Published: July 2023

The Point of Sales (POS) system refers to a system which supports sales transactions where POS is currently growing since it has the ability not only to record sales, record inventory, print invoices, calculate profits but also improve services for business people and entrepreneurs. Super Mama Frozen Food is a store that is currently developing in Malang. In addition, the simple of access to buying products through online services has made the increasing in transactions. However, at Super Mama Frozen Food, most of the data management, data processing, and sales transaction processing have so far relied on a manual or paper-based recording system. As a result, this condition may open up risks in both data management and security. By designing a website-based Point of Sales System, recording sales, collecting inventory, printing invoices, and calculating profits can be done using the PHP programming language with the CodeIgniter framework and MySQL. This system was developed using the Agile Method with the reason that short-term system design can increase client satisfaction

Politik Hukum Pembentukan Peraturan Perundang-Undangan Pasca Perubahan Kedua Undang-Undang Nomor 12 Tahun 2011
Authors: Febriani Nadia Ayu , Wasti Ryan Muthiara
Published: July 2023

Article 22A of the 1945 Constitution of the Republic of Indonesia mandates the establishment of a rule regarding the law-making process, which serves as a guideline for the law-making process from its inception until the regulation is enacted to the public. However, in its implementation, problems are still related to the law-making process in Indonesia. This normative research uses a statutory and conceptual approach that specifically looks at "over regulated" or "legal obesity” to analyze the legal politics of the formation of laws and regulations after the second amendment of Law Number 12 of 2011 concerning the Establishment of Laws and Regulations. In this context, there is an overlap between one law and another, which creates sectoral egos and results in legal uncertainty in its application. One of the causes of this legal obesity is the lack of regularity in the law-making process. In this case, legislators do not always refer to the guidelines for the law-making process and the principles for forming statutory regulations as stipulated in the law-making process regulation. In addition, the law still needs to be optimal in fulfilling meaningful participation. Therefore, the author will analyze the politics of law of the amendments of law-making process regulation after the Constitutional Court Decision Number 91/PUU-XVIII/2020, which includes accommodating the omnibus method and the concept of meaningful community participation as a solution for overlapping legislation in Indonesia.
Omnibus Law dalam Konstitusi Indonesia

Published: July 2023

The Omnibus Law is often discussed and debated, especially in its implementation in Indonesia. Omnibus Law is considered as a solution to make legislation more efficient, Omnibus Law is something new in the formation of legislation in Indonesia. Previously, the Omnibus Law was often used in the common law legal system, and several civil law countries have also implemented the Omnibus Law. In this study, the authors examine the United States and the Philippines. The concept of the Omnibus Law is not only used for one type of law but has penetrated into other sectoral laws. In the Philippines, since 2003 the Omnibus Law has been enacted as a method for forming legislation. It is different from the United States, which has implemented the Omnibus Law since 1850. This research refers to a comparison of the Omnibus Law in the Philippines because the Philippines is a country in the Southeast Asia region just like Indonesia and adheres to a legal system that combines common law and civil law which does not very different from Indonesia, further comparison with the United States Omnibus Law, because the United States is also one of the countries that is the mecca of world law. This study uses normative legal research, using secondary data which is processed using qualitative techniques. This study uses a comparison of two countries which makes this research different from other research related to the Omnibus Law, with the aim of examining the position of the Omnibus Law in Indonesia and making comparisons with the United States and the Philippines.

QS. al-An'ām [6]:108 contains the prohibition of insulting and degrading the worship of other religions. The purpose of this prohibition is to prevent the polytheists from insulting Allah in return for the insults made by the Muslims. The content of this verse suggests several principles of tolerance that need to be known and practiced by a plural society. This paper aimed to examine the verse in the framework of thematic interpretation and its correlation with the principles of tolerance in the Indonesian context. This research is a library research using thematic interpretation method. The focus of the theme in this study was the principle of tolerance implied in QS. al-An'ām [6]:108 which is then associated with the Indonesian context. The author can conclude three principles of tolerance based on this verse; First, not to defame the worship of other religions. Second, recognizing the existence of other religions. Third, preaching with good words. In the context of Indonesia, which consists of a plural society, these three principles are very important to maintain the harmony of religious life in the midst of the onslaught of various intolerant individuals and groups.

This research attempts to trace the most significant development caused by the information revolution, namely "the Communication Technology" which reduced the distances between different urban communities, or within a single one, eliminated the geographical boundaries and the transformed the world into a global village. This led to the emergence of new forms and bodies to those urban communities; perhaps the most important is the fragmentation of the major cities and the emergence of (Satellite Cities) with global links, rather than hinterlands to the local capital cities as in the past. But in spite of the technological tide of communications and its inevitable impacts, it stays, with all its possibilities, a reaction that occurs only in one direction and within the limits of no more than sending and receiving nothing more. This is what Arab cities had seen in the recent stages of their change.Here arises the problem of the emergence of the communication act as a "Dogmatic" because the whole world revolved around the communications network ... Which in turn became the heart of the system of this era. In light of this problem, this research has sought to find the act parallel if not alternative that will fold the " Communication " between its wings, making it, the stage of the process of response and interaction surpassing the limits of sending and receiving. In other words the transition fromimporting technology to the process of contributing to its production. This only takes place through the investment of the Communications Technology to achieve that which is the highest and noblest, posed in this research by the "Communicativeness" between communities. To achieve this goal it took the building of the theoretical framework, in the light of which we put forward the hypothesis of the research that reads (Communication in its technological dimension and Communicativeness in its social dimension, both, play a role in the formulation of Satellite Cities of the twenty-first century through their essential impact on the physical, social and economic infrastructure development of those cities). The research, then, sought to test the validity of this hypothesis and draw conclusions and recommendations.

Authors: Sarsam Saad I. , Al-Rawi Abeer A. , Abdul Rahim Ahmed S.
Published: July 2023

Roller compacted concrete (RCC) is a concrete compacted by roller compaction. The concrete mixture in its unhardened state must support a roller while being compacted. The aim of this research work was to investigate the behavior and properties of roller compacted concrete when constructed in the laboratory using roller compactor manufactured in local market to simulate the field conditions. The roller compaction was conducts in three stages; each stage has different loading and number of passes of the roller. For the first stage, a load of (24) kg and (5) passes in each direction had been employed. For the second stage, a load of (104) kg and (10) passes in each direction were conducted. Finally, at the third stage, a load of (183) kg and (15) passes were adopted. Such procedure was in accordance to previous work conducted by the author. The effects of the type of coarse aggregate (crushed and rounded), fine aggregate (river and natural) and cement type (OPC and SRPC) on the mechanical properties of RCC were investigated. The effect of compaction method on compressive strength and indirect tensile strength was also discussed. A total of (26) roller compacted concrete slab samples of (380×380×100 mm) were prepared in the laboratory, Then, the slab specimens are taken out of the molds and immersed in the curing tank for (28) days. Core and Beam specimens were obtained from the slab samples for the determination of mechanical properties. Such properties include compressive, indirect tensile, flexural strengths using one point loading. It was concluded that the compressive strength of RCC using crushed aggregate is higher than that when using rounded aggregate in a range of (15-66) % for core specimens, while the compressive strength of RCC when using river sand is higher than that when using natural sand in a range of (9-26)% for core specimens. When river sand is implemented, RCC samples show higher indirect tensile strength than those with natural sand, such variation is within (7-8) %

Published: July 2023

Corrosion inhibiting admixtures are unique among other methods to protect reinforced concrete from corrosion damage. In this study, the effect of furfural on the fresh and hardened properties of concrete mixes of 35 and 45 MPa compressive strengths as well as the corrosion inhibition of furfural was evaluated. Furfural was added at different dosages (1, 2 and 3% by weight of cement) with and without superplasticizer (HRWR). Different electrochemical measurements were performed (Half-cell potential, Tafel plot and linear polarization resistance). Electrochemical measurements confirmed that furfural dramatically reduces the rate of corrosion; the inhibition efficiencies were 62.7 and 63.8 % due to 3% furfural addition to 35 and 45MPa-concretes respectively. Results also showed that the combined presence of furfural and HRWR was found to provide an excellent corrosion protection to steel.

Preparation of Design Charts for Estimation of the Length of an Upstream Impervious Blanket in a Homogenous Earth Dam
Authors: Mahmood Raghad Samir
Published: July 2023

Earth dams are constructed mainly from soil. A homogenous earth dam is composed of only one material. The seepage through such dams is quite high. Upstream impervious blanket is one of the methods used to control seepage through the dam foundations. Bennet's method is one of the commonly used methods to design an impervious upstream blanket. Design charts are developed relating the length of blanket, total reservoir head, total base width of the dam (excluding downstream drainage), the coefficient of permeability of the blanket material, blanket thickness, foundation thickness, and coefficient of permeability of the foundation soil, based on the equations governing the Bennet's method for a homogenous earth dam with a blanket of uniform thickness. The length of the upstream impervious blanket can be determined by using the developed charts. The length of the blanket is inversely proportional to the coefficient of permeability of the blanket material. The length of blanket is directly proportional to the total reservoir head, total base width of the dam (excluding downstream drainage), blanket thickness, foundation thickness, and coefficient of permeability of the foundation soil.

Authors: Sulaymon Abbas Hameed , Ebrahim Shahlaa Esmail , Ridha Mohanad Jasim Mohammed
Published: July 2023

The biosorption of lead (II) and chromium (III) onto dead anaerobic biomass (DAB) in single and binary systems has been studied using fixed bed adsorber. A general rate multi- component model (GRM) has been utilized to predict the fixed bed breakthrough curves for single and dual- component system. This model considers both external and internal mass transfer resistances as well as axial dispersion with non-liner multi-component isotherm (Langmuir model). The effects of important parameters, such as flow rate, initial concentration and bed height on the behavior of breakthrough curves have been studied. The equilibrium isotherm model parameters such as maximum uptake capacities for lead (II) and chromium (III) were found to be 35.12 and 23.84 mg g-1 respectively. While pore diffusion coefficients (Dp) were obtained to be 7.23×10-11 and 3.15×10-11 m2 s-1 for lead (II) and chromium (III) respectively from batch experiments. The results show that the general rate model was found correct for describing the biosorption process of the dynamic behavior of the DAB adsorber column.

Remediation of Groundwater Contaminated with Copper Ions by Waste Foundry Sand Permeable Barrier
Authors: Faisal Ayad Abedalhamza , Ahmed Maryam Dheyauldeen
Published: July 2023

The permeable reactive barrier (PRB) is one of the promising innovative in situ groundwater remediation technologies, in removing of copper from a contaminated shallow aquifer. The 1:1- mixture of waste foundry sand (WFS) and Kerbala’s sand (KS) was used for PRB. The WFS was represented the reactivity material while KS used to increase the permeability of PRB only. However, Fourier-transform infrared (FTIR) analysis proved that the carboxylic and alkyl halides groups are responsible for the sorption of copper onto WFS. Batch tests have been performed to characterize the equilibrium sorption properties of the (WFS+KS) mix in copper- containing aqueous solutions. The sorption data for Cu+2 ions, obtained by batch experiments, have been subjected to the Langmuir and Freundlich isotherm models. The Langmuir model was chosen to describe the sorption of solute on the solid phase of PRB. COMSOL Multiphysics 3.5a based on finite element method was used for formulation the transport of copper ions in two- dimension physical model under equilibrium condition. Numerical and experimental results proved that the PRB plays a potential role in the restriction of the contaminant plume migration. A good agreement between the predicted and experimental results was recognized with mean error (ME) not exceeded 10 %.

Authors: Almilly Raghad Fareed Kassim , Alobaidy Asrar Abdullah , Alhassani Maha Hadi
Published: July 2023

This research presents a new study in reactive distillation by adopting a consecutive reaction . The adopted consecutive reaction was the saponification reaction of diethyl adipate with NaOH solution. The saponification reaction occurs in two steps. The distillation process had the role of withdrawing the intermediate product i.e. monoethyl adipate from the reacting mixture before the second conversion to disodium adipate occurred. It was found that monoethyl adipate appeared successfully in the distillate liquid. The percentage conversion from di-ester to monoester was greatly enhanced (reaching 86%) relative to only 15.3% for the case of reaction without distillation .This means 5 times enhancement . The presence of two layers in both the distillate and residual liquids was noticed ,the upper (water) layer and the lower (ester) layer. However, water layer was dominant in the distillate .The percentage excess of NaOH solution was calculated with respect to the concentration of monoester (9%-79%) and it was found that increasing the concentration of NaOH solution( until 40%) led to increase in the percentage conversion to monoester. It also led to get a pure monoester in the distillate and made the residual liquid appear as one layer. Maximum conversion had been occurred in the rang (40%-60%). After 60% the percentage conversion lowered noticeably.

This work dealt with separation of naphthenic hydrocarbons from non-naphthenic hydrocarbons and in particular concerns an improved process for increasing the naphthenes concentration in naphtha, The separation was examined using adsorption by Y and  B zeolite in a fixed bed process. The concentration of naphthenes in the influent and effluent streams was determined using PONA classification. The effect of different operating variables such as feed flow rate (2- 4 L/hr); bed length (50 - 80 cm) on the adsorption capacity of Y and  zeolite was studied. Increasing the bed length lead to increase the naphthenes concentration, and increasing the flow rate lead to decrease in the concentration of naphthenes, It was found that the decrease in flow rate to 2 L/hr and increase the bed length to 80 cm lead to increase the naphthenes concentration from 6.2 to 24.8 Wt. %.
