Full text linkManajemen Public Relations di Program Corporate Social Responsibility PT SIER Dalam Community Development dan Corporate Social Innovation
Full text linkThis study analyzes public relations (PR) management in the Corporate Social
Responsibility (CSR) program of PT Surabaya Industrial Estate Rungkut (SIER) for
community development and corporate social innovation (CSI). Using a qualitative
descriptive approach, the study explores the four PR stages—finding the fact and
defining the problem, planning and programming, taking action and communication,
and evaluating the program. PT SIER implements CSR through community relations,
community service, and community empowerment, which include MSME
empowerment, infrastructure development, and digital marketing training. However,
the awareness stage in community development remains suboptimal due to the absence
of social mapping. The capacity-building stage involves funding and training, while
the empowerment stage focuses on international collaboration such as business
matching. PT SIER's CSR program also adopts CSI principles: multisectoral
collaboration with governments and strategic partners, sustainable innovation in
digital training and water recycling, and alignment with business to create shared
value. The results show that PT SIER has designed and implemented programs to
enhance the capacity and independence of the community. However, strengthening
long-term monitoring systems and developing formal social mapping are necessary to
ensure program sustainability. This study contributes theoretically to the study of CSR
based on community development and the practice of corporate social innovation

Pra Rancangan Pabrik Metil Etil Keton (2-Butanon) Dari 2-Butanol Dengan Metode Dehidrogenasi
No full textA Methyl Ethyl Ketone (MEK) plant with a capacity of 50,000 tons per year will be established in Manyarejo, Manyar District, Gresik Regency, East Java. The plant will operate 24 hours a day and 330 days a year. The MEK plant will use 2-butanol from Yujiang Chemical (Shandong) Co., Ltd in China and Copper Catalyst from PT. Hunan Minstrong Technology Co., Ltd in Hunan, China.
Methyl ethyl ketone is an important solvent with properties similar to acetone. MEK has advantages over other solvents, including a comparable evaporation rate, high solubility ratio to viscosity, ability to mix with large amounts of hydrocarbons without affecting solid content or viscosity, and good volume/mass ratio due to its low density. In general, MEK is a competitor to ethyl acetate as a low-boiling-point solvent due to its low viscosity, high solid content, and large dilution tolerance.
The MEK plant uses a dehydrogenation process with CuO catalyst. The process starts with pre-treatment by evaporating 2-butanol. The first step is dehydrogenation in a fixed-bed multitube reactor with CuO catalyst at 380°C. The gas produced is then separated from unwanted substances, such as nitrogen and water, using a flash drum. The next step is to separate the MEK and water components in a distillation column. The separated MEK gas is then condensed and cooled before entering the product tank.

Pabrik Difenilamin Dari Anilin Dan Katalis Alumina Aktif Dengan Proses Alkilasi Kapasitas 50.000 Ton/Tahun
No full textBerikut adalah terjemahan teks tersebut dalam bahasa Inggris:
Diphenylamine (DPA) or N-phenylbenzenamine is one of the chemical materials that must be imported from abroad to meet domestic needs. This is because Indonesia does not yet have a factory that produces diphenylamine. The establishment of a diphenylamine factory in Indonesia is expected to reduce dependence on imported products, not only diphenylamine products but also other products that use diphenylamine as a raw material, thereby encouraging the growth of downstream industries related to or using diphenylamine products. Diphenylamine is used as a stabilizer for elastomers, nitrocellulose, nitroglycerin, and as an intermediate for dyes. In addition, diphenylamine is also used as an additive in propellants to increase storage power by neutralizing acidic products formed from the decomposition of nitrocellulose.
According to UN Comtrade (2024), the total import of diphenylamine commodities in the country in 2024 was 46,337 tons per year. The demand for diphenylamine in Indonesia is expected to continue to increase in line with the increasing human needs and the growth of downstream industries in Indonesia that require diphenylamine as a raw material. Planning for the establishment of a diphenylamine factory with a capacity of 50,000 tons/year can help meet domestic needs.
The location of the factory is a crucial aspect that must be considered. Based on several considerations, the diphenylamine factory will be established in the JIIPE Gresik Industrial Area, Jalan Raya Manyar KM 11 Manyarejo, Manyar Sidorukun, Manyar District, Gresik Regency, East Java 61151.
In general, diphenylamine can be produced through liquid-phase conversion and vapor-phase conversion processes. The process chosen in this factory design is the vapor-phase conversion process. The process starts with vaporizing aniline using a vaporizer. The resulting vapor is then heated with a furnace to a temperature of 460°C, which is then compressed to 7 atm. The vapor is then flowed into the reactor with an operating temperature of 460°C and a pressure of 7 atm with active alumina catalyst in the reactor tube. The aniline vapor will decompose into diphenylamine vapor and ammonia by-products. The mixture of diphenylamine vapor, ammonia, and unreacted aniline is separated in a separator. The bottom product of the separator is liquid-phase diphenylamine, which is then crystallized using a prilling tower and stored in a storage warehouse. The top product of the separator is a mixture of ammonia and unreacted aniline, which is separated again in separator 2. The bottom product of separator 2 is unreacted aniline, which is then flowed back to the vaporizer as a recycle. The top product is ammonia gas, which is stored in an ammonia storage tank.
The utility unit in the diphenylamine factory serves to provide auxiliary materials and energy. In the water treatment unit, sanitary water, process water, cooling water, and boiler feedwater are provided. To conserve water, the used cooling water must be cooled again in a cooling tower. In the steam supply unit, the boiler is planned to produce saturated steam at a pressure of 4.5 bar with a temperature of 148°C.
The main product sold is diphenylamine with a price of $437 per 100 kg. The economic analysis shows that the Total Capital Investment is Rp1,163,755,457,051 with a Return on Investment after tax of 16%. The Break-Even Point is 32.85% with a Payback Period of 2 years and 2 months

No full textThe use of technology in the entertainment industry has advanced rapidly, including the application of gamification in education. This study aims to design and develop an educational application based on a Role-Playing Game (RPG) with turn-based mechanics to enhance high school students' learning motivation. The application was developed using the Multimedia Development Life Cycle (MDLC) method, which consists of six stages: concept, design, material collecting, assembly, testing, and distribution. The application employs character attributes aligned with specific subjects, such as Health Points (HP) for biology, Attack (ATK) for mathematics, Mana Points (MP) for chemistry, Defense (Def) for Bahasa Indonesia, Critical Rate (Crit Rate) for advanced mathematics, and Critical Damage (Crit DMG) for physics. Students can complete five main levels along with an additional level called Level EX. The application is a web-based platform developed using JavaScript, HTML, and CSS, featuring key elements such as character attributes, quiz practices based on UTBK problems, and combat against mobs. The research findings reveal that gamified quiz practices with an RPG genre can increase students' learning motivation. Testing conducted on 10 students over 15 days, from October 22, 2024, to November 5, 2024, showed that 9 out of 10 students felt motivated to practice quizzes using the application, with 5 students achieving the highest level (Level EX). These results indicate that the RPG-based gamification approach creates an interactive and enjoyable learning experience while helping students enhance their motivation for independent learning

Korelasi Profil Tekstur Pada Nasi Kecambah Beras Merah dengan Menggunakan Pengujian Instrumen dan Profiling Sensori
No full textGerminated red rice is an innovation in food processing aimed at improving the texture quality and nutritional value of red rice. This study aims to analyze the effect of germination on the texture profile of germinated red rice, evaluate the correlation between instrumental and sensory texture analysis, and determine the characteristics of germinated red rice through correlation analysis. The research was conducted using a factorial randomized block design with two factors: red rice variety (Inpari Arumba and Inpari 24) and germination time (0, 12, 24, 36, and 48 hours). The analyzed parameters included amylose content, amylopectin, swelling power, solubility, pasting profile (RVA), and texture profile using the Texture Profile Analysis (TPA) method, along with descriptive sensory evaluation. Additionally, microscopic analysis using Scanning Electron Microscopy (SEM) was performed to observe changes in starch granule structure. Data were analyzed using ANOVA, DMRT test, Pearson Correlation, and Principal Component Analysis (PCA). The results showed that the germination process of red rice led to a decrease in amylose content and an increase in amylopectin, solubility, and swelling power up to a certain duration. The RVA pasting profile results indicated a decrease in peak viscosity with increasing germination time. SEM analysis revealed starch granule structure degradation due to enzymatic activity. Additionally, the germination process could also cause starch structure degradation in germinated red rice flour. Correlation analysis showed a significant positive relationship between instrumental testing results (TPA) and sensory evaluation, particularly in the hardness attribute. PCA successfully grouped texture characteristics based on variety and germination time. This study provides in-depth insights into the physicochemical and textural changes in germinated red rice and highlights its potential development as a functional food product with improved texture and nutrition.
