Tahun 1900 bukan merupakan tahun kabisat karena bilangan 1900 tidak habis dibagi dengan bilangan ....
Correct Answer
C. 400
Explanation
The year 1900 is not a leap year because it is not divisible by 400. In order for a year to be a leap year, it must be divisible by 4, except for years that are divisible by 100. However, if a year is divisible by 400, then it is still considered a leap year. Since 1900 is not divisible by 400, it is not a leap year.

Tahun Kabisat pada perhitungan kalender Masehi terjadi karena ....
Correct Answer
C. Lamanya bumi mengelilingi matahari lebih dari 365 hari
Explanation
A leap year occurs in the Gregorian calendar because it takes the Earth slightly more than 365 days to orbit the Sun. To account for this extra time, an additional day, February 29th, is added to the calendar every four years. This ensures that the calendar stays in sync with the Earth's orbit around the Sun. Therefore, the correct answer is "lamanya bumi mengelilingi matahari lebih dari 365 hari".
3.
Bagian permukaan bulan yang menghadap ke bumi selalu sama. Penyebabnya adalah ....
Correct Answer
D. Kala rotasi bulan sama dengan kala revolusi bulan
Explanation
The correct answer is that the rotation period of the moon is the same as its revolution period around the Earth. This means that the same side of the moon is always facing the Earth.
4.
Jumlah hari dalam satu tahun pada sistem penanggalan yang didasarkan pada revolusi bulan terhadap bumi adalah....
Correct Answer
A. 354 hari
Explanation
The correct answer is 354 days. This is because a lunar calendar is based on the revolution of the moon around the earth, which takes approximately 29.5 days. Therefore, a year in a lunar calendar would consist of 12 lunar months, each with 29 or 30 days, totaling to 354 days. This is shorter than a solar calendar year, which is based on the revolution of the earth around the sun and consists of 365 or 366 days.

Penetapan hari raya Idul Fitri dijadwalkan pada kalender ....
Correct Answer
B. Hijriah
Explanation
The correct answer is "Hijriah" because Idul Fitri is a Muslim holiday that marks the end of Ramadan, the Islamic holy month of fasting. The Islamic calendar, also known as the Hijri calendar, is a lunar calendar based on the sighting of the moon. Therefore, the determination of Idul Fitri is based on the Hijri calendar.
7.
Setiap hari, kita melihat seolah-olah Matahari bergerak dari timur ke barat. Hal ini terjadi karena....
Correct Answer
A. Bumi berotasi dari barat ke timur
Explanation
The correct answer is "bumi berotasi dari barat ke timur." This is because the Earth rotates on its axis from west to east, which creates the illusion of the Sun moving from east to west in our daily experience.
8.

Correct Answer
C. Belahan bumi utara dan selatan secara bergantian condong ke arah matahari atau menjauhi matahari sehingga terjadi perubahan musim
Explanation
The correct answer explains that the tilt of the Earth's axis causes the northern and southern hemispheres to alternately tilt towards or away from the sun, resulting in changes in seasons. This tilt affects the amount of sunlight each hemisphere receives, leading to variations in temperature and weather patterns throughout the year.

Bulan adalah satelit yang setia mengorbit bumi. Bidang orbit bulan memiliki kemiringan sekitar .... terhadap bidang ekliptika bumi.
Correct Answer
B. 5 derajat
Explanation
The correct answer is 5 derajat. The explanation for this is that the moon's orbit around the Earth is tilted at an angle of approximately 5 degrees with respect to the Earth's ecliptic plane. This tilt is what causes the moon to appear at different positions in the sky throughout its orbit.
11.
Kala rotasi bulan sama dengan kala revolusinya. Hal tersebut mengakibatkan....
Correct Answer
C. Permukaan bulan yang menghadap ke bumi selalu sama
Explanation
The rotation period of the moon is the same as its revolution period, which means that the same side of the moon always faces the Earth. This is why the surface of the moon that is visible from Earth remains constant, resulting in the statement that the surface of the moon that faces the Earth is always the same.
12.
Bumi berputar pada sumbunya sebanyak ... dalam 24 jam.
Correct Answer
A. 1 kali
Explanation
The correct answer is "1 kali" because the Earth completes one full rotation on its axis in 24 hours, which is equivalent to one day. This rotation causes day and night cycles on Earth.
13.
Kala rotasi bulan adalah ....
Correct Answer
C. 29 hari
Explanation
The correct answer is 29 days. The rotation of the moon on its axis takes approximately 29 days. This means that it takes the moon around 29 days to complete one full rotation. This is why we always see the same side of the moon from Earth.
14.
Pada tanggal 21 Maret-21 Juni di belahan bumi utara mengalami musim ....
Correct Answer
A. Semi
Explanation
The correct answer is "semi". Pada tanggal 21 Maret-21 Juni di belahan bumi utara mengalami musim semi. This means that between March 21st and June 21st in the northern hemisphere, the season experienced is spring.
15.
TAndi dan Romi sama-sama berumur 4 tahun. Jika umur Andi 4 tahun dalam tahun masehi dan umur Romi 4 tahun dalam tahun hijriah, selisih umur mereka dalam hitungan hari adalah ....
Correct Answer
B. 44 hari
Explanation
The question states that Andi's age is 4 years in the Gregorian calendar (year Masehi) and Romi's age is 4 years in the Hijri calendar (year Hijriah). The difference in their ages in terms of days can be calculated by finding the difference in the number of days between the two calendars. As the Gregorian calendar has 365 days in a year and the Hijri calendar has 354 or 355 days in a year, the difference in days would be 365 - 355 = 10 days per year. Therefore, the difference in their ages would be 4 years x 10 days/year = 40 days. However, since Andi's age is ahead by 4 years, the total difference in days would be 40 days + 4 days = 44 days.
16.
Jika belahan Bumi selatan sedang musim panas, belahan Bumi utara mengalami musim....
Correct Answer
A. Dingin
Explanation
When the southern hemisphere is experiencing summer, the northern hemisphere is experiencing winter. This is due to the tilt of the Earth's axis. During summer, the sun's rays hit the southern hemisphere more directly, resulting in warmer temperatures. Conversely, the northern hemisphere is tilted away from the sun during this time, leading to colder temperatures and winter conditions. Therefore, the correct answer is "dingin" which means "cold" in English.
17.
Gerhana matahari terjadi jika ….
Correct Answer
B. Sinar matahari terhalang bulan
Explanation
During a solar eclipse, the moon moves between the sun and the earth, blocking the sunlight from reaching the earth's surface. This is why the correct answer is "sinar matahari terhalang bulan" which translates to "sunlight is blocked by the moon".
18.
Peredaran bumi mengelilingi matahari disebut ....
Correct Answer
D. Revolusi
Explanation
The correct answer is "revolusi" because it refers to the Earth's movement around the sun. This movement is known as revolution, and it takes approximately 365 days to complete one revolution.
19.
Kalender atau penanggalan dibuat berdasarkan pada peristiwa alam, salah satunya adalah ...
Correct Answer
A. Terjadinya fase-fase bulan
Explanation
Kalender atau penanggalan dibuat berdasarkan pada peristiwa alam, salah satunya adalah terjadinya fase-fase bulan. Fase-fase bulan terjadi karena perubahan posisi relatif antara Matahari, Bumi, dan Bulan. Bulan mengelilingi Bumi dan menerima cahaya dari Matahari. Saat Bulan berada di sisi yang sama dengan Matahari, kita melihat fase Bulan baru. Ketika Bulan berada di sisi yang berlawanan dengan Matahari, kita melihat fase Bulan purnama. Fase-fase Bulan ini membantu dalam mengatur kalender dan penanggalan karena siklusnya yang teratur dan dapat diobservasi dengan mudah.
20.
Ada 2 peristiwa kemungkinan yang terjadi jika kedudukan matahari, bumi dan bulan sejajar atau berurutan yaitu purnama dan gerhana bulan, hal ini terjadi karena....
Correct Answer
A. Kemiringan bidang orbit bulan terhadap bidang ekliptika bumi
Explanation
The correct answer is "kemiringan bidang orbit bulan terhadap bidang ekliptika bumi." This is because the alignment of the sun, earth, and moon in a straight line can result in either a full moon or a lunar eclipse. The inclination of the moon's orbit with respect to the earth's ecliptic plane determines whether the moon passes through the earth's shadow during a lunar eclipse or is fully illuminated during a full moon.
21.
Gerakan bumi berputar pada porosnya disebut ....
Correct Answer
C. Rotasi
Explanation
Rotasi adalah gerakan bumi yang berputar pada porosnya sendiri. Gerakan ini menyebabkan pergantian siang dan malam serta perubahan posisi bintang dan matahari di langit. Revolusi adalah gerakan bumi mengelilingi matahari, bukan gerakan berputar pada porosnya sendiri. Reformasi adalah perubahan atau perbaikan dalam sistem atau kebijakan yang ada. Orbit adalah jalur yang dilalui oleh benda langit saat bergerak mengelilingi benda lain dengan gaya gravitasi.
22.
Selisih kalender Islam dengan kalender Masehi dalam setahun adalah ....
Correct Answer
C. 11 hari
Explanation
The Islamic calendar is based on the lunar calendar, which consists of 354 or 355 days in a year. On the other hand, the Gregorian calendar, commonly known as the Masehi calendar, is a solar calendar with 365 or 366 days in a year. The difference between the two calendars is approximately 11 days. This is because the lunar year is shorter than the solar year, causing the Islamic calendar to lag behind the Gregorian calendar by about 11 days each year.
23.
Tanggal 1 Muharam 1433 H bertepatan dengan 15 November 2012. Namun, 1 Muharam 1434 H ternyata bertepatan dengan 5 Nopember 2013. Hal ini terjadi karena ....
Correct Answer
C. Kala revolusi bulan lebih cepat daripada kala revolusi bumi
Explanation
The correct answer is "kala revolusi bulan lebih cepat daripada kala revolusi bumi". This means that the lunar revolution (the time it takes for the moon to orbit the Earth) is faster than the Earth's revolution around the Sun. As a result, the Islamic calendar, which is based on the lunar cycle, moves forward approximately 10 to 12 days each year compared to the Gregorian calendar, which is based on the Earth's revolution around the Sun. Therefore, the dates of Islamic events, such as the start of the month of Muharram, do not align exactly with the dates in the Gregorian calendar.
24.

Correct Answer
B. Bayangan umbra tidak sampai ke bumi dikarenakan bulan berada pada titik terjauhnya dengan bumi
Explanation
During an annular solar eclipse, the moon is at its farthest point from the Earth, causing the shadow of the moon (umbra) to not reach the Earth's surface completely. This results in a ring of sunlight being visible around the moon, creating the appearance of a "ring of fire" during the eclipse.
25.
Berikut adalah peristiwa-peristiwa alam ;1) pergantian siang dan malam2) perbedaan waktu3) gerak semu harian matahari4) terlihatnya rasi bintangberdasarkan peristiwa tersebut, yang termasuk akibat rotasi bumi adalah peristiwa nomor ....
Correct Answer
A. 1, 2 dan 3
Explanation
The events mentioned in options 1, 2, and 3 are all caused by the rotation of the Earth. The rotation of the Earth causes the alternation between day and night (event 1), the difference in time zones (event 2), and the apparent daily motion of the sun across the sky (event 3). These events are all directly related to the Earth's rotation and its effect on our perception of time and the movement of celestial bodies.
