Qual è la differenza tra enak e sedap ?Sentiti libero di rispondere con un esempio.

Hello, chone-san!

The difference between 'enak' and 'sedap' according to KBBI (or The Official Dictionary of Indonesian), I added also Japanese definition, just in case:

1.Enak means 美味しい or うまい
a.) sedap, lezat (ttg rasa - about taste) - 味
Sedap = nice, delicious, tasty, pleasant, well-made food.
Explains about the pleasant feeling gained from our 'taste' sensor/sense (i.e: tounge) or from our 'smell' sensor/sense (i.e: nose)
Contoh (Example):
Kue ini enak rasanya. (This cookie/cake tastes delicious).
Baunya enak ya! (Hey, it smells good!)

b.) sehat atau segar (tt kondisi badan - about body condition): 体が良いor 気分が良い
Sehat = healthy, fit, well in a sense you feel great (not sick) (explains about body condition, how fit your body is)
Segar = healthy, in a fresh sense (explains usually when you have just taken your bath and feeling well and fresh, similar feeling with "Fresh from the oven" ).
Contoh (Example):
Hari ini saya kurang enak badan. ( I feel unfit/unwell today)
However, it is highly unusual if you say "Hari ini saya enak badan". (Today I feel fit/well )

c.) nikmat atau menyenangkan (tt perasaan, suasana, dsb - about feeling, atmosphere, etc) - 楽しいこと, 嬉しいこと, 享楽気分
Nikmat atau menyenangkan = good, enjoyable or pleasure-inducing feeling ( about feeling, atmosphere, situation, etc)
Nyaman = comfortable (some meanings are better translated with fresh, but the feeling conveyed is 'comfortable')
Contoh (Example):
-> Setelah mandi dengan air hangat, badan terasa enak (After taking a shower with hot water, I feel fresh).
-> Berendam air panas memang benar-benar enak. (Soaking in hot water definitely feels great!)

d.Pulas; Lelap (tt tidur - about sleep/slumber) - 春眠, ぐっすり眠ります
Pulas: (fast) and sound (about sleep quality) - usually deep sleep implied where you won't get awakened easily. Also, conveys that you're well-rested after the sleep.
Lelap: sound (about sleep quality) -
Contoh (Example):
Pada malam itu, tidurnya enak sekali (At that night, he was fast asleep) or (At that night, he slept soundly)

2.Sedap means 香ばしい or 良い風味
a.Enak - delicious, savory, tasty, it's (about 風味, 味), usually food that freshly served.
Contoh (Example):
Makanan ini rasanya sedap. (This food tastes delicious) - It is implied that the food tastes delicious and also smells good.

b.Beautiful, pretty (奇麗, 美人)
Contoh (Example):
Perempuan itu sedap dipandang mata. (That girl is beautiful) - (literal translation: That girl is 'delicious' to be looked/stared at)

c.Harum (Fragrant - about pleasant-inducing aroma/scent)
Contoh (Example):
Baunya sedap. It smells good. (or fragrant).

Hey, I saw that your native language is Japanese, so I added some 'nearest' Japanese counterpart for the word.
Conclusion:
enak = 美味しい, うまい (mostly for food, body condition, work condition, condition/atmosphere)
sedap = 香ばしい, 良い風味 (mostly for food and taste/smell, rarely used for other usage in conversation)

Enak is a general term to describe the pleasant feeling of our sense(s)
Sedap is a specific term to describe the pleasant feeling of usually our smell (olfactory) or taste sense. If you want to describe that lots of mixed seasoning is added into a cooking/food and it feels great, you can say 'sedap' for specific term.

While "enak" and "sedap" can be used interchangeably, it is not in some cases such as:

1.In case of bodily function or feeling, 'enak' conveys fitness, healthy condition. Usually used in negative sense (+kurang/tidak)
-> Kurang enak badan = feeling unwell, unfit
-> Tidak enak badan = feeling sick (気分が悪い) - stronger feeling
-> Kurang/Tidak sedap badan (x) (wrong)

2.In case a specific flower called: sedap malam (olianthes tuberosa).
You can't say enak malam (x) (wrong).

Actually there are lots of other usage that differentiate between 'enak' dan 'sedap' in its inflected form such as:
-> pe+sedap => penyedap (flavoring agent)
-> pe+enak => pengenak (x) (wrong)

Hope this helps ^_^.
