Abstract

Toraja arabica coffee is well known for its higher price and quality compared to robusta coffee, but its commercial is often added with other ingredients, including robusta coffee which has low economic value. Visual inspection is unreliable in roasted ground coffee due to the resemblance of its chemical content. The ATR-FTIR method tandem PCA was able to provide an overview of the typical chemical content of the coffee preparation. The purpose of this study was to evaluate the robusta coffee as adulterant in Toraja arabica coffee preparation by using ATR-FTIR. Toraja arabica coffee beans were obtained from three smallholder plantations around Toraja and Robusta coffee beans were obtained from Toraja, Lampung, and West Java coffee plantations. The coffee beans were roasted and then macerated using 96% ethanol for 3×24 hours and concentrated using a rotary evaporator until being thick. The IR spectrum of each extract was measured using the ATR-FTIR spectroscopy at a range of 4000-650 cm-1. The results show there is a similarity in the IR spectrum patterns and there is only a small difference in the transmittance of Toraja arabica coffee and robusta coffee. Furthermore, the IR spectrum is clustered by using PCA in R program. The projection of three commercial samples shows that samples 1 and 2 do not contain robusta coffee while sample 3 shows the presence of robusta coffee. In conclusion, the ATR-FTIR spectroscopic method tandem PCA was able to clustered the presence or absence of robusta coffee content in the Toraja arabica coffee.

It is very interesting to study about improving learning outcomes with quizizz paper mode in learning with RME for students. With this type of qualitative research using pre-test and post-test instruments. The instrument was validated by experts with valid results. While the teacher observed the implementation of RME learning with the results that all steps could be carried out. The results of the research are that it can increase student learning outcomes to 86% of the remaining completion. So an increase of 50% of the results at the beginning of learning. The application of the quizizz paper mode can be continued by adding validation to the teacher's teaching documents.

Abstract

This research is a pre-experimental research study aimed to determine whether the Learning Starts With A Question method has an effect on improving the IPAS learning outcomes of fourth-grade students at SD Inpres 3/77 Bajoe 1. The research design used is One-Group Pretest-Postest Design. The population in this study were all of the fourth-grade students of SD Inpres 3/77 Bajoe 1 with a sample of 19 students selected based on the saturated sample technique. The data obtained were then analyzed using a paired sample t-test with a significance level of 5%. From the results of the data analysis, it was obtained that tcount = 8.785> ttable = 2.100. So, t count> ttable then H0 is rejected which means that the IPAS learning outcomes before and after the implementation of the Learning Starts With A Question method differ significantly. Because the average IPAS learning outcomes of students after the implementation of the Learning Starts With A Question method are higher than before the implementation and the average is significantly different, it can be said that the Learning Starts With A Question method has a significant effect on improving the IPAS learning outcomes of students in grade IV of SD Inpres 3/77 Bajoe 1, Tanete Riattang Timur District, Bone Regency.

Abstract

Kebutuhan akan layanan bimbingan konseling seperti Unit Pelayanan Teknis Bimbingan Konseling (UPT BK) pada Universitas Negeri Makassar semakin penting di kalangan masyarakat khususnya bagi mahasiswa. Hadirnya layanan bimbingan konseling, di harapkan menjadi ruang bagi mahasiswa untuk mengekspresikan diri dan mengungkapkan berbagai permasalahan yang sedang dialami. Akan tetapi, semua fungsi layanan UPT BK ini belum sepenuhnya dapat dirasakan mahasiswa di UNM khususnya bagi mahasiswa yang berkampus di luar kota Makassar seperti kampus V Pare-Pare dan Kampus VI Bone. Ada 5 akar penyebab masalah ini yakni: 1) system layanan bimbingan konseling masih berfokus pada kegiatan konvensional yakni tatap muka secara langsung, 2) kurangnya sosialisasi layanan BK 3) kurangnya kolaborasi antara penyedia layanan pusat dengan pihak kampus diluar kampus utama (UNM Pare-pare dan PGSD Bone), 4) jarak antara mahasiswa PGSD Bone FIP UNM dengan pusat layanan cukup jauh, dan 5) kecenderungan mahasiswa gen Z pada layanan berbasis online. Untuk itu, penulis memfokuskan upaya penanganan masalah kurang optimalnya penggunaan layanan bimbingan konseling bagi mahasiswa PGSD Bone dengan mengupayakan suatu solusi berupa pengabdian yakni “ Sosialisasi Layanan Konseling Berbasis Web Bagi Mahasiswa PGSD Bone”.
