Tamansari 20, Bandung 40116, Indonesia 3) RS Paru Dr.H.A Rotinsulu, Jl. Bukit Jarian 40, Bandung 40141, Indonesia Abstract Indonesia is the second largest of tuberculosis (TB) endemic country in the world and affected by devastated coronavirus disease 2019 (COVID-19) pandemic. The clinical manifestation caused by co-infection of TB and COVID-19 in Indonesia is unknown. Vital signs are standard clinical manifestation examined during hospitalisation. We aimed to analyse the vital signs of hospitalized COVID-19 patients who had TB co-infection and had no TB infection. We conducted a retrospective study using medical record of patients who had confirmed COVID-19 and hospitalized in Dr. Rotinsulu Lung Hospital from January 2020 to December 2021. TB and COVID-19 co-infected group (TB COVID) was firstly screened as those had both diagnosis confirmed COVID-19 and TB during hospitalisation in electronic medical record. The COVID group was those without TB diagnose during hospitalisation and randomly selected for minimum sample size. Vital signs (systolic and diastolic blood pressure, respiratory rate and O2 saturation) were data firstly recorded during hospitalisation. The differences of vital signs between two group were analysed by Mann-Whitney. The 165 participants enrolled compromised 83 (50.3%) TB co-infection and 82 (49.7%) no TB infection. TB COVID had lower (p=0.0096) median systolic blood pressure (mmHg) (118 (IQR 110-128)) than COVID (120 (IQR 116-132)). The median diastolic blood pressure (80 mmHg) in both of group was similar. The median for respiratory rate in TB COVID was 23 (IQR 22-24) and not significantly different to that in COVID (p=0.54). TB COVID had significant higher (p=0.0238) median O2 saturation (%)(97 (IQR 94-98)) than COVID (96 (IQR 93-97). In conclusion, this study showed that median for vital signs in both of groups was in normal range. COVID-19 patients co-infected with TB had lower systolic blood pressure and higher O2 saturation. Co-infection of TB is unlikely to have detrimental effect on initial vital signs in hospitalised COVID-19 patients.

THE EFFECT OF GYPSUM (CaSO4) ON THE VALUE OF COHESION AND ANGLE OF FRICTION USING DIRECT SHEAR STRENGTH TEST Iswandaru, Rully Nurhasan R, Eka Adhitya K. Universitas Islam Bandung Abstract Clay soil is a type of soil that has the characteristics of large shrinkage, this makes clay an unfavorable material in a construction work. Low bearing capacity can lead to instability of a building foundation erected on clay soil and the swelling and shrinkage properties of clay can cause cracks in highway pavements, also rupture or breakage on the ground floor of the dam. In the construction of civil buildings, the cohesion and shear strength of the subgrade have an effect on the planning of a building, so soil stabilization can be carried out before the soil is used. One of the efforts to improve soil stabilization is mixing soil with certain materials in order to improve the technical properties of the soil to meet certain requirements by increasing soil parameters such as density, cohesion, and shear strength. The soil stabilization process includes mixing with gypsum material (CaSO4) to obtain the desired gradation so that the soil properties become better with calcium levels that bind organic matter to clay and also absorb more water which is very useful for strengthening soil. The research was conducted by testing the direct shear strength of the soil (Direct Shear Test) by adding different percentages of Gypsum (CaSO4) ranging from 5% - 10%. The effect of the addition of gypsum on the cohesion value and the optimum internal friction angle occurred in the addition of 7% lime with a value of 0.018 MPa and 24.93o.

In Law No. 17 of 2019 concerning Water Resources Article 29 states that the utilization of water resources does not only include surface water, groundwater, or seawater, but also rainwater. Uncontrolled use of groundwater can cause adverse impacts, including groundwater crises, land subsidence, or seawater intrusion. Therefore, alternative use of other water sources is needed, namely rainwater. The challenge faced in utilizing rainwater as a source of raw water is the existence of rainwater that is not continuous and is strongly influenced by the seasons, so an effort is needed to harvest rainwater that can be used also when there is no rain. This research is focused on analyzing the chemical quality of the results of mixing between groundwater and rainwater at the research site. The samples used were 2 samples from rainwater and 2 samples from groundwater. Based on the chemical quality test of the sample, it shows that if a mixture of 10%-90% ratio of rainwater and groundwater is carried out, the water quality criteria fall into the Class II category. Based on Government Regulation (PP) Number 22 of 2021 for the Implementation of Environmental Protection and Management, this category is intended for freshwater fish cultivation, livestock, and water for irrigating plants or other uses that require the same water quality as these uses.

Observation and Simulation of Traffic Congestion using SimEvents MATLAB Erwin Harahap (a*), Farid Badruzzaman (b) a) Department of Mathematics, Universitas Islam Bandung Jalan Ranggagading No. 8, Bandung 40116, Indonesia *erwin2h[at]unisba.ac.id b) Department of Management, Universitas Teknologi Digital, Jl. Buah Batu No. 26, Bandung 40262, Indonesia Abstract Congestions are events that severely hamper community activities. Generally, congestion occurs caused by too many vehicles with very limited road capacity. However, it has to be a proof that the congestions occur because of these two factors. There are several factors that caused congestion, such as people activities, bad drivers, u-turn, crossing, etc. Cinunuk road lies on Cibiru-Cileunyi line, located at the sub-district of Cileunyi, Bandung district, West Java, Indonesia. This location is usually congested over time, and become one of the most congested street in Bandung district. The Cinunuk street currently is the only one main non-toll street that connect that connects cities in the western and northern regions of the West Java province to the south or east regions. The result is high traffic density which causes traffic congestion throughout the day, specifically in the morning (06:00 to 09:00) and late afternoon (15:00 - 18:00). However, congestion also often occurs outside of these hours. In this article, a study is conducted to analyze on what exactly causes the traffic congestion in the Cinunuk line, therefore some strategic steps have to be taken to reduce congestion. We propose a modelling of situation based on observation through the causes of the congestion, using queuing models to compare the level of congestion before and after certain steps are carried out, and then simulate it using the MATLAB SimEvents application. Through this method, hopefully solution can be found to reduce the traffic congestion.

In this paper, the authors design a real-time Cigarette Smoke Detection System (SPAR) based on the MQ-2 sensor and the ESP32 microcontroller. SPARs are placed in certain locations that can monitor an area. The MQ-2 sensor is used to detect the presence of smoke (including cigarette smoke) in the form of an analog signal. This signal is then translated into digital code and read by the ESP32 microcontroller. Furthermore, ESP32 sends a command to a buzzer to give a response in accordance with the program code that has been designed. The buzzer will respond as alarm sound, which indicates that cigarette smoke has been detected around the area. Through this alarm sound, the competent authorities can immediately provide an appropriate response. The results of research and experiments have succeeded in making SPAR tools and functioning well in detecting cigarette smoke.

Aerobic Composting Process Development Using Perforated Brick Construction Method by increasing the airflow Mohamad Satori, Endang Prasetyaningsih, Puti Renosari, Fariz izzulhaq, Ira Ayu Wulandari Bandung Islamic University Jalan Tamansari No.1 Bandung, Indonesia Faculty of Engineering Abstract Waste can contribute to environmental issues, but it also contains potential resources that can be generated and used by the community. Waste utilization based on characteristics is following Waste Management Law No. 18 of 2008. Previous research indicates that the composition of the household and similar waste is dominated by organic waste accounting for 50-60%. The organic waste can be converted into compost, which can be used to enrich agricultural soil. A perforated brick construction method (metode Bata Terawang) with the open windrow principle is a well-known composting method in Indonesia, where the supply of oxygen and moisture must be an essential consideration. The aeration system in the composting with the perforated brick construction is typically accomplished in two ways: by creating hollows in the brick construction or by placing perforated pipes crosswise in the middle of the composter tube. This study attempted to place a perforated pipe into the aeration process and periodically add airflow from a blower. The results show that adding airflow will speed up the composting process, while the quality of the compost produced is drier due to the lower water content.

Identifying The Frozen Food Business Omni-Channel Retail Strategy in Bandung Djamaludin, Nita Puspita, Selamat Industrial Engineering - Universitas Islam Bandung Abstract Micro, Small, and Medium Enterprises or commonly abbreviated as MSMEs are business groups managed by certain people or business entities whose criteria are determined based on Law Number 20 of 2008. Currently, there are more than 65 million MSMEs spread across Indonesia [3], while in Bandung City, West Java Province, there are around 160,000 [6]. In this study, one example of a frozen food company in the city of Bandung, which has the characteristics of the small business category [10], has an average sales turnover of 30 million per month, employees are less than 10 people, various frozen food products are their own production, run a business for more than 3 years, have resellers < 10, sales are carried out through the social media network whatsapp only. From the results of the initial research, it can be seen, from the product side and buyer experience, it is found that the products produced by the company are very satisfying and unique, and in terms of sales channels, they have not reached the electronic market or resellers in cities spread across Java. Therefore, it can be seen that there is a great opportunity to develop and expand its market reach through various sales channels both online and offline. This research is a start to determine a more appropriate omni-channel retail strategy in its development and implementation. The results showed the need for an integrated and efficient system in terms of product management, inventory, marketing sales, reporting from various channels that will be entered by the company. Companies can choose and utilize the right technology according to the needs and financial capabilities of the company. This can be done by calculating the Return on Investment (ROI) of the creation or utilization of software and related infrastructure, namely by measuring the potential of software applications and related infrastructure, to increase revenue, reduce costs, increase customer satisfaction, and achieve operational efficiency.

IMPLEMENTATION OF GREEN MANUFACTURING AND LEAN MANUFACTURING IN THE TANNERY INDUSTRY Aviasti Aviasti (a*), Asep Nana Rukmana (b), Chaznin R.M.(c), Reni Amaranti(d), Deva Akbar(e), Ari Ramdani(f) (a) Program Studi Profesi Insinyur Fakultas Teknik Universitas Islam Bandung * Aviasti98[at]gmail.com (b,c,d,e,f) Program Studi Teknik Industri Fakultas Teknik Universitas Islam Bandung Abstract The leather tanning industry is an industry that converts raw animal skins into tanned leather through three stages: beam house, tanning, and post-tanning stages. In recent times, the leather tanning industry in Indonesia has experienced a setback due to the lack of availability of raw leather raw materials in the country, the unconnected user industry with the national leather tanning industry, as well as increasing regulations that must be met related to chromium content in water. Green manufacturing leads to the minimization of negative impacts on the environment from design to the end of the product life cycle. Green manufacturing practices are defined as manufacturing practices that can meet consumer needs while simultaneously complying with environmental regulations. Lean manufacturing is one of the best practices in manufacturing that teaches simplification through waste elimination that can be applied to very complex and non-integrated processes. Lean manufacturing can be said to be manufacturing without waste, so the main principle of this approach is the reduction of waste in the manufacturing function. This article will discuss the implementation of green manufacturing and lean manufacturing, as an effort to overcome the problems experienced by the leather tanning industry, especially those related to environmental issues.

Optimization of The Fish Port Queuing System Ahmad Arif Nurrahman, Otong Rukmana, Ajrina Febri Suahati, Hideo Darell Marvian, Elsa Novia Sari Universitas Islam Bandung Abstract The background of this study is the constraints of the queuing system that occurred at karangsong indramayu port. Karangsong Port plays an important role in supporting the fishing industry sector in Indramayu. Based on the results of previous research, the facilities and infrastructure at Karangsong Port are still inadequate, such as the Fish Auction Area (TPI), labuh ponds, and parking areas whose capacity is still lacking. In addition, there is a queue of fishing boats that want to unload the catch. Although the fish unloading process is in accordance with standard operating procedures (SOP), there are still queues of vessels. This queue obstacle must be solved considering that Karangsong Port has a high level of activity in supporting the fishing industry sector in Indramayu. In addition, efforts to optimize the fishing boat queuing system need to be carried out, in line with the steps of the local and central governments through the MPA which currently has planned to carry out various constructions of facilities and infrastructure at Karangsong Port.

INDUSTRIAL SYMBIOSIS MODEL IN LEATHER PROCESSING INDUSTRY CENTER Aviasti Aviasti(1)*, N Nugraha(1), and R Amaranti(2) (1)Program Studi Profesi Insinyur Fakultas Teknik Universitas Islam Bandung (2)Program Studi Teknik Industtri Fakultas Teknik Universitas Islam Bandung (1)*Correspondence author E-mail: Aviasti98[at]gmail.com Abstract One of the manufacturing industries that has the potential to have an impact on the environment is the leather processing industry. The leather and leather goods industry consists of industries that process raw leather into leather and leather goods industries. The leather tanning industry is an industry that converts raw animal skins into tanned leather through three stages: beam house, tanning, and post-tanning stages. This tanned leather is then used as raw material for the manufacture of various leather products such as shoes, bags, jackets, belts, and other leather crafts. The leather tanning industry produces liquid and solid wastes that have the potential to have a negative impact on the environment. Meanwhile, industries that make leather products produce solid waste in the form of patchwork. If the disposal of the leather patch accumulates for a long time, it will certainly be a problem for the surrounding environment. Industrial symbiosis is a form of cooperation between different industries. This form of cooperation can increase the profits of each industry and ultimately have a positive impact on the environment. This article will discuss how the leather tanning industry and the leather processing industry work together to minimize the waste generated.

Gen. Gatot Subroto 10, Jakarta 12710. Abstract Digitalization in economic processes and governance requires a fast, efficient and secure process. Digital signatures help digitization run quickly and securely. It makes it easy for those who adopt it. Several users benefit from digital signatures (Ministry of Communication and Information Technology, Ministry of Finance. This study aims to overview the problems in adopting this digital signature technology. This qualitative research collects data from some registered Electronic Certification Providers. This study found obstacles to the adoption of digital signatures. Constraints in the adoption of this technology are inharmonious regulations and literacy. For example, authentic meanings must be made before a Notary to meet the requirements for verification and fulfillment of the Power of Authentication Deed. This study suggests that the government ( Ministry of Law and Human Rights) harmonizes regulations related to digital signatures. Meanwhile, literacy improvement aims to increase awareness about digital signatures. As a regulator, the Ministry of Communications and informatics needs to help other institutions adopt digital signature technology, prepare infrastructure, and encourage the use of digital signatures in society.
