The Diffrences in Student’s Grade Point Average (GPA) Based on SBMPTN of UTBC and UTBK and External Motivation in Choosing PMIPA Majors of Tadulako University

This study aims to describe the differences in student's GPAs at the Mathematics and Natural Science Education (PMIPA) Department of Tadulako University who enter through the Joint Selection to Enter State Universities (SBMPTN) pathway with the Print-Based Written Test (UTBC) in 2018 and Computer-Based Writing Examination (UTBK) systems in 2019, describe the relationship of external motivation of students in choosing majors with GPA based on the SBMPTN (UTBC and UTBK) pathway. The samples used were all students at the PMIPA Study Program of Tadulako University who entered through the UTBC SBMPTN pathway in 2018 as many as 134 students and 130 students of UTBK 2019. There is an insignificant difference in the students' GPA through the UTBC and UTBK SBMPTN pathway. The students of UTBK have a higher GPA in the second semester than the students of UTBC, with the average GPA of UTBC students is 3.407, and the average GPA of UTBK students is 3.525. There is no relationship between students' external motivation in choosing a major against students' GPA at the PMIPA department of Tadulako University, but factors of interest and self-will influence it

PENGUATAN BUDAYA LITERASI EKOLOGIS DI SEKOLAH

Abstrak: Tingkat literasi peserta didik di Indonesia masih berada pada kategori rendah. Pengabdian kepada masyarakat (PKM) dilakukan untuk menguatkan budaya literasi ekologis peserta didik di Sekolah Bala Keselamatan Palu terhadap 56 orang peserta didik baru. Penyuluhan dilakukan melalui ceramah, tanya jawab, dan simulasi menggunakan presentasi dan video tentang isu-isu fenomena ekologis dengan tujuan: (1) Membangun budaya literasi ekologis; dan (2) Membangun perilaku go green school. Hasil evaluasi melalui tanya jawab sepanjang penyuluhan menunjukkan rata-rata persentase “Membangun budaya Literasi Ekologis” sebesar 60,4% dan “Membangun perilaku dan go green school activity” sebesar 84,9%. Hasil evaluasi melalui observasi dan wawancara seminggu setelah penyuluhan menunjukkan adanya kreativitas kelompok “Sasisapo” melakukan proyek “perubahan iklim global” dengan merawat tanaman setiap hari seusai sekolah, menanam tanaman (bunga-bunga dan dua pohon akasia), dan bersih-bersih lingkungan sekolah setiap hari Sabtu. Diharapkan hasil PKM ini menjadi masukan terhadap guruguru dalam menginternalisasi nilai-nilai budaya literasi ekologis pada pembelajaran di kelas.Abstract: The literacy level of students in Indonesia is still in the low category. Community service (PKM) is carried out to strengthen the ecological literacy culture of students at the Palu Salvation Army School for 56 new students. Counseling is carried out through lectures, questions and answers, and simulations using presentations and videos on issues of ecological phenomena with the aim of: (1) Building a culture of ecological literacy; and (2) Building go green school behavior. The results of the evaluation through questions and answers during the extension showed that the average percentage of "Building an Ecological Literacy culture" was 60.4% and "Building behavior and going green school activity" was 84.9%. The results of the evaluation through observations and interviews a week after the extension showed the creativity of the "Saisapo" group in carrying out a "global climate change" project by taking care of plants every day after school, planting plants (flowers and two acacia trees), and cleaning the school environment every day. Saturday. It is hoped that the results of this PKM will become input for teachers in internalizing the cultural values of ecological literacy in classroom learning

Analisis Vitamin C pada Buah Pepaya, Sirsak, Srikaya dan Langsat yang Tumbuh di Kabupaten Donggala

Vitamin C is known as ascorbic acid. The function of vitamin C is to help the synthesis of collagen and antioxidants that the body needs. Vitamin C can be obtained from fruits, and each fruit had different levels of vitamin C. This study aims to determine the levels of vitamin C in the fruit papaya, soursop, sugar apple and complexioned fruit. This study uses a volumetric method that uses a solution of iodine (I2) as the titer, and using starch as an indicator, and each piece studied every day for three days with the same treatment. The results obtained levels of vitamin C in papaya fruits in a row are the first day of 46.89 mg, the second day 34.6 mg, third day and 22.88 mg. Vitamin C in the complexioned fruits are the first day 82.28 mg, the second day 61.31 mg, and third day 37.14 mg. Vitamin C in the sweetsop fruit are the first day 49.83 mg, the second day 35.2 mg, and third day 20.46 mg. And the soursop fruit vitamin C content was obtained on the first day 62.42 mg, the second day 33.44 mg, and third day of 23.14 mg. The results demonstrated that levels of Vitamin C in four fruits had decreased each day since the time of storage
