The average import of benzoic acid in Indonesia is 8,339 tons per year (BPS, 2023). It is expected that …
Attira Denova ABSTRACT The polymer industry is one of the basic materials industries that is quite popular because of its widespread use in life. The development of the polymer industry began in 1839, with the discovery of vulcanization by Charles Goodyear. Until 1970 there were more than 25 polymer products produced and this continues to increase to this day. The important role of polymers i…
ABSTRACT Methyl Methacrylate is a chemical compound used in various industries such as leather coating, cosmetics, paint, household equipment, polymer, and other industries. Methyl Methacrylate is produced through the oxidation process of Isobutylene. The plant is planned to operate for 330 days per year, running continuously 24 hours per day, with a production capacity of 38,000 tons per year…
ABSTRACT In Indonesia, caprolactam is not yet produced domestically, thus the demand must still be met through imports from other countries. Over the past five years, the volume of caprolactam imports has remained relatively high, ranging between 30,000 and 35,000 tons annually. Caprolactam is produced via the Toyo Rayon Photonitrosation process. This process aims to convert cyclohexane into c…
ABSTRAK Indonesia is one of the developing countries, which continues to experience growth. The need for acrylonitrile is quite large in Indonesia. However, currently, the need for acrylonitrile is used as an intermediate chemical component in the manufacture of acrylic fibers, plastic, synthetic rubber and many other products. The purpose of the preliminary design of this factory is to meet d…
ABSTRACT This research aims to design a Catechol plant from Phenol using the Hydroxylation process with the main tool design for Distillation (T-103).Catechol is a toxic organic compound in the form of a crystalline powder that can be used as an important intermediate in the manufacture of pesticides and medicines. The factory is planned to be located in Cilegon, West Java, under the name …
ABSTRACT Methyl ester sulfonate (MES) is a group of anionic surfactants made through the sulfonation process. Methyl ester sulfonic acid is used to make liquid detergents. In Indonesia, there are not many factories or producers of methyl ester sulfonic acid so that imports are made to meet the needs. Therefore, the processing of methyl ester sulfonic acid is needed to meet the needs of methyl …
ABSTRAC In today’s digital era, the availability of a stable and efficient internet network is a crucial need to support teaching and learning activities in educational environments. SMAN 12 Pekanbaru, as one of the schools implementing technology-based learning, is experiencing issues related to uneven Bandwidth distribution, especially during peak usage hours. This often disrupts access to…
ABSTRACT Academic communication between students and lecturers in the Informatics Engineering Study Program at Universitas Riau currently relies on general platforms such as WhatsApp and email. This leads to issues such as the mixing of academic and personal messages, as well as difficulties in documentation and searching for discussion topics. This study aims to design and develop a web-based…
ABSTRACT The academic guidance process in the Informatics Engineering Study Program at Universitas Riau is still carried out informally through platforms such as WhatsApp, resulting in a lack of documentation, slow communication, and minimal supervision from the head of the program. This study aims to develop a web-based academic guidance reservation system to make the guidance process more or…
ABSTRACT The environmental pollution that is the center of attention is industrial waste. Adsorption has been shown to be a more effective method for absorbing heavy metals from wastewater. The adsorbent commonly used in adsorption is activated charcoal. Yellow bamboo is a material that can produce charcoal by carbonization. The aim of this research is to make adsorbents from bamboo, to ch…
ABSTRACT Chip quality is very important as it affects the next stages of production. Chip quality includes parameters such as accept, reject, overthick, pin fraction, fines, and chip length. This study analyzed the effect of different wood species on chip quality, specifically Acacia mangium, Acacia crassicarpa, and Eucalyptus. This study was conducted by analyzing secondary data in 8 days at …
ABSTRACT A winder machine is a machine that functions to roll a jumbo roll and cut the roll where the rolls will later be adjusted to customer demand. During the winding process, problems are often found in the form of defects or defects in sheeter roll products, which can affect the physical quality, aesthetics, and performance of the product when used by end customers. These defects can appe…
ABSTRACT Delco Citra Arengka Housing in Pekanbaru is one of the areas affected by waterlogging during high-intensity rainfall, indicating that the existing drainage system is not functioning optimally.
