Pabrik Isooktana Dari Diisobutilene Dan Hidrogen Dengan Proses Hidrogenasi
Get PDFAn isooctane production plant with a capacity of 120,000 tons per year is planned to be established in Bontang, East Kalimantan. The plant will operate continuously for 24 hours per day and 330 days per year. The main raw materials used are Diisobutylene (C₈H₁₆) and Hydrogen (H₂). Diisobutylene is sourced from the dimerization of Isobutylene, while hydrogen is supplied from the plant’s internal storage system. The production process involves a hydrogenation reaction carried out in a fixed-bed catalytic multitube reactor using Nickel (Ni) and Alumina (Al₂O₃) catalysts under high temperature and pressure. The reaction achieves high conversion efficiency, and the resulting isooctane (C₈H₁₈) is purified through distillation to meet the required product specifications. As a high-octane hydrocarbon, isooctane serves as a key component in premium gasoline and environmentally friendly fuels.
The plant employs a Line and Staff organizational structure and is designed to accommodate 189 personnel. Supporting utilities include steam, electricity, process and cooling water, and fuel, with respective capacities of approximately 90.98 kg/h of steam, 311.1 kWh of electricity, 6,614.73 m³/day of water, and 0.14 L/h of fuel. The total land area required for the facility is around 35,800 m².
The economic evaluation indicates the feasibility of the project, with key parameters including a 2-year construction period, 10-year plant life, Fixed Capital Investment (FCI) of Rp 1.521 trillion, Working Capital (WC) of Rp 758.6 billion, and a Total Production Cost (TPC) of Rp 4.55 trillion. The project demonstrates a Return on Investment (ROI) of 16.06%, an Internal Rate of Return (IRR) of 10.14%, a Payback Period (PBP) of 3 years and 5 months, and a Break-Even Point (BEP) of 31.03%. Based on these indicators, the proposed isooctane plant is considered economically feasible for implementation

Get PDFAnalisis Perbandingan Quantity Pekerjaan Struktur Pile Cap Berbasis Mutual Check 0 Menggunakan Autodesk Revit (Studi Kasus: Proyek Pembangunan Gedung Jirona Rumah Sakit Aisyiyah Bojonegoro)
Get PDFIn the development of this construction project, various methods are used to calculate the volume of work items, one of which is the use of BIM-based (Building Information Modelling) applications. In the Ji’rona Building Construction Project, the need for fast and accurate calculations, cost projections, and structural work volume estimations is highly crucial. This can be easily achieved through the implementation of BIM. The purpose of this study is to implement the procedure for modeling pile cap structures using the BIM-based software Autodesk Revit to obtain quantities, and then compare them with the volumes listed in the Mutual Check 0 (MC-0) document. This research uses a quantitative approach that involves data quantification to compare the concrete and reinforcement quantity calculations for pile caps between Autodesk Revit and the MC-0 document. The pile cap modeling was carried out in Autodesk Revit by importing an AutoCAD floor plan as a reference for creating grids and levels, and by adjusting the pile cap family according to the shop drawings. The pile caps were modeled with main reinforcement of Ø25 mm, stirrups of Ø16 mm, and a concrete cover thickness of 100 mm in accordance with the technical specifications. Clash detection was performed using Navisworks Manage to analyze reasonable clashes or correct unreasonable clashes before re-evaluation. The results show that the total difference in concrete material quantity is 1.2 m³ with a deviation of 0.15%. The total difference in reinforcement quantity is 1,023.49 kg with a deviation of 0.89%. The total net concrete volume produced using Revit is 801.24 m³, while the net concrete volume in the MC-0 document is 802.31 m³. Therefore, the difference between MC-0 and Revit for concrete work is 1.07 m³. For both materials, the quantities obtained from the MC-0 data are greater than those calculated using Autodesk Revit
PENGARUH SERVICE QUALITY, KEBIJAKAN PRICE DISCOUNT, DAN PRODUCT KNOWLEDGE TERHADAP BRAND TRUST PADA TIKTOK LIVE STREAMING PINKFLASH INDONESIA
Get PDFThis research is motivated by the phenomenon of increasing use of TikTok Live Streaming as a promotional medium and consumer interaction by cosmetic brands, one of which is Pinkflash Indonesia. This phenomenon shows a shift in digital marketing patterns, where consumers not only buy products based on needs, but also because of trust in brands built through real-time direct interactions. In this context, the study focused on how service quality, price discount policies, and product knowledge can affect brand trust during TikTok Live Streaming sessions. This research aims to find out the meaning behind interactive marketing strategies and their influence on the formation of brand trust in Pinkflash Indonesia. The method used was an associative quantitative approach with a data collection technique through purposive sampling on 156 respondents who had watched TikTok Live Streaming Pinkflash at least twice. The data was processed using SPSS with Classical Assumption Test, Hypothesis Test and Multiple Linear Regression Analysis. The results showed that the three independent variables simultaneously had a significant positive effect on brand trust. However, partially, only service quality and price discount policies have a significant effect, while product knowledge has a negative effect on the positive. This research emphasizes the importance of choosing service strategies and price promotion policies in building trust in brands, especially in a competitive digital environment such as TikTok Live Streaming

Pengaruh Content Marketing, Diskon, dan Live Shopping Terhadap Perilaku Pembelian Impulsif Konsumen (Studi Kasus Pada Akun Tiktok Shop @Sattka.basic)
Get PDFThis study aims to analyze the influence of content marketing, discounts, and live shopping on consumers' impulsive buying behavior on the TikTok Shop account @Sattka.Basic. The research employs a quantitative method with a descriptive and causal approach. Data were collected through online surveys conducted with followers of the @Sattka.Basic account. Data are measured using a Likert scale, and the analysis process includes validity, reliability, classical assumptions, F tests, and t tests. The results indicate that simultaneously, content marketing, discounts, and live shopping significantly influence impulsive buying behavior. However, partially, only content marketing significantly affects impulsive buying behavior, while discounts and live shopping do not have a significant impact. These findings suggest that creative and engaging content marketing is more effective in driving impulsive purchases compared to discounts and live shopping in this case. Companies can increase repurchase intention by strengthening brand image through storytelling, influencers, and CSR, maintaining product quality through innovation and attractive packaging, and implementing content marketing at social media included TikTok. Promotions also need to be optimized with loyalty programs and engaging digital activities, including social media and online ordering platforms.

REPRESENTASI FEMININITAS JAWA KONTEMPORER DALAM AKUN TIKTOK RANIA YAMIN @raniaayamin (Studi Semiotika Model John Fiske)
Get PDFDi masa lampau, konsep femininitas sering kali dibatasi oleh konstruksi sosial yang mengharuskan perempuan untuk sesuai dengan ekspektasi tertentu, seperti bersikap lembut, penuh pengertian, dan selalu mengutamakan peran pengasuhan Penelitian ini bertujuan untuk menganalisis representasi femininitas Jawa kontemporer pada akun TikTok Rania Yamin (@raniaayamin) dengan menggunakan pendekatan semiotika televisi dari John Fiske. Dalam konteks budaya digital, media sosial seperti TikTok menjadi ruang strategis untuk membentuk dan menyampaikan nilai-nilai budaya serta identitas gender. Melalui tiga level analisis semiotik yaitu realitas, representasi, dan ideologi pada penelitian ini menemukan bahwa konten-konten Rania Yamin merepresentasikan nilai-nilai femininitas Jawa seperti kesopanan, kelembutan, dan kepatuhan dalam format yang estetik dan komunikatif. Dalam konteks ideologi, hasil penelitian menunjukkan bahwa konten Rania membawa ideologi femininitas Jawa tradisional yang dikemukakan oleh Clifford Geertz, seperti andhap asor (rendah hati), laku pasrah (berserah diri), dan pengendalian diri yang tinggi. Dengan demikian, dari sudut pandang Geertzian, konten Rania menegaskan kembali peran perempuan sebagai penjaga harmoni sosial dan simbol kesopanan dalam tatanan budaya Jawa.
