📊 Problem Summary You’re given: Cost of Product A: $6,000 Cost of Product B: $3,000 Total Sales: $20,000 You need to find: Sales of Product A Sales of Product B 🧠 Step-by-Step Solution 1. Add the total cost of both products: Total Cost = 6,000 + 3,000 = 9,000 2. Calculate each product’s cost proportion: Product A: 6,000 ÷ 9,000 = 0.6667 (or 2/3) Product B: 3,000 ÷ 9,000 = 0.3333 (or 1/3) 3. Apply those proportions to the total sales: Sales of Product A = 0.6667 × 20,000 = $13,333.33 Sales of Product B = 0.3333 × 20,000 = $6,666.67 ✅ Final Answer Product           Cost           Sales Allocation Product A           $6,000           $13,333.33 Product B           $3,000           $6,666.67 Total           $9,000         ...

Introduction In project and operation management, ensuring tasks are executed in the most efficient manner is essential to avoid delays and cost overruns. One of the most powerful scheduling tools available to engineers is the Critical Path Method (CPM) . It helps identify: Which activities directly determine the total project duration. Where flexibility (slack/float) exists in scheduling. How to prioritize limited resources effectively. Key Concepts Activities (Tasks) The fundamental building blocks of a project. Each requires time and possibly resources. Dependencies Logical relationships between activities. Example: Task B cannot start until Task A is completed. Critical Path The longest sequence of dependent activities in a project network diagram. Determines the minimum project duration . Any delay in the critical path → directly delays the project. Slack (Float) The amount of time a non-critical activity can be delayed without af...

🛠️ Dari Pikiran ke Realitas: Panduan Praktis Desain Mekanis 1. Kenali Perangkap Kebuntuan Pikiran Desain mekanis sering dimulai dari ide dan perhitungan di kepala. Namun, terlalu lama berada di tahap ini dapat menimbulkan analysis paralysis . Kesalahan umum: Menunggu desain "sempurna" sebelum memulai. Mengabaikan efek dunia nyata (gesekan, toleransi, ekspansi termal). Terlalu terikat pada konsep awal yang belum teruji. Intinya: Berpikir itu penting, tetapi tidak dapat menggantikan pengujian. 2. Dasarkan Diri pada Teori Desain yang kuat berawal dari fondasi teoritis yang kokoh . Hal ini memastikan konsep Anda layak sebelum masuk ke tahap pemodelan atau pembuatan prototipe. Bidang pengetahuan inti: Statika & dinamika → gaya, gerakan, keseimbangan. Ilmu material → tegangan, regangan, kelelahan, elastisitas. Termodinamika & mekanika fluida → perpindahan energi, perilaku aliran. Desain untuk manufaktur (DFM) → metode produksi dan ba...
