### 1. Executive Summary / Quick Answer
Under Indonesian Labor Law, a labor contract clause establishing a standard workweek of **50 regular hours is legally unenforceable and null and void (*batal demi hukum*)**.
Indonesian law strictly caps standard working hours at **40 hours per week**. While an employee may physically work up to 50 hours in a given week, the **10 hours exceeding the 40-hour threshold must be legally treated, agreed upon, and compensated as statutory overtime (*kerja lembur*)**, subject to statutory overtime caps and mandatory overtime pay calculations. The underlying employment contract remains valid, but the 50-hour standard clause is overridden by statutory limits.

### 3. In-depth Legal Analysis & Rights of Parties

*Exception:* Certain non-standard sectors (e.g., energy, mining, maritime, and offshore plantations) are permitted specialized working shifts regulated under specific Ministerial Regulations (*Permenaker*). Unless the business falls strictly within these specialized industries, a baseline of 50 regular hours violates the law.
