Nā nīnau hoʻohālike e kūkākūkā ana i ka mana o ka wahi Astronomical ma ka mahele ʻana o nā ʻāpana manawa ma Indonesia
He ʻāina pae ʻāina ʻo Indonesia ma waena o nā ʻāina ʻelua, ʻo ʻAsia a me Australia, a me nā moana ʻelua, ʻo India a me ka Pakipika. ʻO ke kūlana hōkū o Indonesia, e moe ana mai ka latitu 6° ʻĀkau a i ka latitu 11° Hema a mai ka latitu 95° Hikina a i ka longitude 141° Hikina, he mea nui ia i ka mahele ʻana o nā ʻāpana manawa ma ka ʻāina holoʻokoʻa. E kūkākūkā kēia ʻatikala pehea e pili ai ke kūlana hōkū i ka mahele ʻana o nā ʻāpana manawa ma Indonesia a hāʻawi i nā nīnau hoʻohālike a me nā kūkākūkā e pili ana i kēia kumuhana.
Ka Mana o ka Wahi Astronomical ma ka Māhele ʻana o nā ʻĀpana Manawa
ʻO Indonesia, ma ke ʻano he ʻāina me ka laulā honua ākea e hoʻolōʻihi ana mai ke komohana a i ka hikina, pono ia i kahi mahele manawa kūpono e hoʻomaʻamaʻa pono ai i nā hana a kona heluna kanaka. Ma muli o kēia wahi hōkū, ua māhele ʻia ʻo Indonesia i ʻekolu mau ʻāpana manawa nui:
1. Manawa Komohana o Indonesia (WIB, GMT+7): Uhi iā Sumatra, Java, a me nā ʻāpana o Kalimantan. Pili ka WIB ma muli o ka longitude o ka ʻaoʻao komohana o Indonesia e kokoke loa ana i GMT+7.
2. Manawa Waena o Indonesia (WITA, GMT+8): Uhi iā Bali, Nusa Tenggara, nā ʻāpana o Kalimantan, a me Sulawesi. Aia kēia ʻāpana ma ka ʻāpana waena o Indonesia, e hahai ana i kahi lōʻihi ma ka hikina iki o WB.
3. Manawa Hikina o Indonesia (WIT, GMT+9): Uhi iā Maluku a me Papua. Aia ma ka ʻaoʻao hikina loa o Indonesia, i hoʻoponopono ʻia no ka lōʻihi ma ka hikina.
ʻAʻole wale kēia mahele ʻana o nā ʻāpana manawa ma muli o ka wahi honua, akā, ua noʻonoʻo pū kekahi i nā ʻano hoʻokele, hoʻokele waiwai, a me nā ʻano nohona-moʻomeheu e kūpono i nā hana maʻamau o kēlā me kēia lā o ka poʻe ma kēlā me kēia wahi.
Nā Nīnau Laʻana a me ke Kūkākūkā
Eia kekahi mau nīnau hoʻohālike e hiki ke kōkua i ka hoʻoikaika ʻana i kou ʻike i ka mana o ka wahi hōkū ma ka māhele ʻana o nā ʻāpana manawa ma Indonesia:
Laʻana Nīnau 1
Nīnau: He aha ka mea e hana ʻia i ka manawa kūloko ma Indonesia inā hoʻoholo ʻia ma muli o ka wahi hōkū me ka ʻole o ka noʻonoʻo ʻana i nā kumu pilikanaka a me ka hoʻokele waiwai?
Kūkākūkā:
Inā hoʻoholo ʻia ka manawa kūloko ma Indonesia ma muli wale nō o ka wahi astronomical (longitude) me ka noʻonoʻo ʻole i nā kumu pilikanaka a me ka hoʻokele waiwai, e ʻike mākou i nā ʻāpana manawa he nui aʻe ma mua o kā mākou i kēia manawa. ʻO kēlā me kēia 15° o ka longitude e hōʻike ana i ka ʻokoʻa manawa hoʻokahi hola. Me nā longitudes mai 95° Hikina a i 141° Hikina, hiki iā Indonesia ke loaʻa ma mua o ʻekolu mau ʻāpana manawa. Eia nō naʻe, i ka ʻoiaʻiʻo, pono e kūlike ka hoʻokaʻawale ʻana o ka manawa me ke ola socio-economic, e like me nā hola hana a me nā hana kaiāulu, no laila ua wehewehe wale ʻia he ʻekolu mau ʻāpana nui: WIB, WITA, a me WIT.
Laʻana Nīnau 2
Nīnau: Aia kekahi kūlanakauhale X ma 120° Hikina. I ka hola 12:00 awakea manawa kūloko ma ke kūlanakauhale X, he aha ka manawa i hōʻike ʻia ma ke kūlanakauhale Y aia ma 95° Hikina?
Kūkākūkā:
No ka hoʻoholo ʻana i ka ʻokoʻa manawa ma waena o nā kūlanakauhale ʻelua, pono mākou e helu i ka ʻokoʻa o ka longitude a hoʻololi iā ia i ka manawa. ʻO ka ʻokoʻa o ka longitude ma waena o ke kūlanakauhale X a me ke kūlanakauhale Y penei:
120° Hikina Longitude – 95° Hikina Longitude = 25°.
No ka mea, ʻo kēlā me kēia ʻokoʻa 15° ma ka lōʻihi ua like ia me 1 hola, a laila:
25° / 15° = 1,67 hola.
A i ʻole ma kahi o 1 hola a me 40 mau minuke.
No ka mea aia ke kūlanakauhale ʻo X ma ka hikina o ke kūlanakauhale ʻo Y, e lohi ka manawa ma ke kūlanakauhale ʻo Y ma mua o ke kūlanakauhale ʻo X. No laila, inā he 12.00 awakea ma ke kūlanakauhale ʻo X, a laila ʻo ka manawa ma ke kūlanakauhale ʻo Y he 12.00 - 1 hola 40 mau minuke = 10.20 am.
Laʻana Nīnau 3
Nīnau: Inā hele kekahi mai Jayapura (135° Hikina Longitude) a i Jakarta (106° Hikina Longitude) a hōʻea i ka hola 18.00 WIT, i ka manawa hea e hōʻea ai ʻo ia i ka manawa kūloko o Jakarta (WIB)?
Kūkākūkā:
ʻO ka mea mua, hoʻoholo mākou i ka ʻokoʻa manawa ma muli o ka ʻokoʻa o ka longitude ma waena o Jayapura lāua ʻo Jakarta:
135° Hikina Longitude – 106° Hikina Longitude = 29°.
29° / 15° = 1,93 hola.
No ka mea, 1 hola = 60 mau minuke, a laila 0,93 hola = ma kahi o 56 mau minuke.
ʻOiai ʻo Jayapura (WIT) he GMT+9 a ʻo Jakarta (WIB) he GMT+7, ʻo ia hoʻi he ʻokoʻa manawa 2 hola ma waena o Jakarta a me Jayapura; ʻO Jakarta he 2 hola ma hope o WIT.
No laila, inā hōʻea ʻoe i Jayapura i ka hola 18.00 WIT, a laila ma Jakarta penei:
18.00 WIT – 2 hola = 16.00 WIB.
Ka hopena
ʻO ka wahi ākea o Indonesia ma ka honua he hopena ia i nā mahele o nā ʻāpana manawa he mea nui ia no ka hoʻomaʻamaʻa ʻana i nā uaki olaola o kānaka a me ka hana waiwai. ʻOiai hiki iā Indonesia ke loaʻa nā ʻāpana manawa hou aʻe, ua koho ʻo ia e hoʻokaʻawale i kona manawa i ʻekolu mau ʻāpana nui e hoʻomaʻalahi i nā hoʻoponopono manawa i ke ola o kēlā me kēia lā.
Pono e hoʻomaopopo pono ʻia kēia mahele, ʻoiai mai nā kuanaʻike kumumanaʻo a me nā kuanaʻike hana, a pehea e hiki ai i nā ʻokoʻa manawa ke hoʻopilikia nui i nā ʻano he nui o ke ola, mai ka hoʻonohonoho ʻana i nā hana a hiki i ke kamaʻilio honua. No laila, he mea nui kēia ʻike ʻaʻole wale ma kahi ʻano honua akā i nā pilina ākea ma ka pae honua.
