You may think years of being a techie is adequate preparation or taking a few classes in high school or college, but it's no substitute for working with a good SM or two. As you can see, SMs have to have people skills, technical skills, foresee problems, and be organized as hell. This position obviously takes a very precise type of person!  While, yes, a good SM can locate a screwdriver in seconds and get to working on a breaking set piece, they can also coordinate with directors and actors -- two very different types of people -- and predict their problems. A good SM has multiple types of intelligence, quite obviously. Fine line, huh? You must be likeable but also be able to maintain your authority so that the cast and crew listens to you and respects you. If you aren't likeable no one will ever want to work with you again; if you aren't respected as an authority you cannot ensure the safety of the cast and crew. As you can see, you are an integral cog in the machine of the show. If you don't lead, chaos will ensue.  Establish control from the very first audition. Though a stage manager should not be feared, they should be respected. No need to scare people into listening to you, but don't be afraid to be firm when you need to be. Expect respect from the beginning of the process and respect the ones around you as well. It's important that you have the keen ability to maintain the artistic and technical integrity of the show. It is your job as an SM to maintain the director's vision during the performances of the show, whether there are 5 performances or 500. If things change, you need to rein 'em back in. Even if you disagree, it's still your job. Does the director want the scene lit so dim that you can barely see the actors? Well...okay. Sure. That's how it's going to work for the rest of the run -- even when the director doesn't show up. If you don't do anything else on this page, take this one little grain of wisdom seriously: It's absolutely imperative that you stay calm. If you lose your cool, everyone...

How would you rephrase that briefly using Indonesian?
