Abstract

Penelitian ini adalah penelitian eksperimen yang bertujuan untuk mengetahui karakteristik komposit ZnO-bentonit hasil sintesis. Tahapan penelitian terdiri dari preparasi dan akivasi bentonit menggunakan H2SO4, sintesis komposit ZnO-bentonit dengan metode impregnasi dan karakterisasi komposit ZnO-bentonit menggunakan XRD dan SEM –EDX. Hasil penelitian menunjukkan Bentonit dan komposit ZnO-bentonit dengan karakterisasi instrumen XRD masing-masing menunjukkan terbentuk puncak pada 2θ = 20-62 dan 2θ = 31-57 yang masing-masing mengindikasikan adanya montmorilonit dan ZnO. Karakterisasi morfologi menggunakan instrumen SEM-EDX menunjukkan ZnO berwarna putih tersebar diatas permukaan bentonit yang ditandai dengan hasil EDX dengan persentase O sebesar 90,55% dan sisanya terdapat unsur lain seperti Al (Aluminium) 8,65 %, P (Phsphorus) 0,43 % dan S (Sulphur) 0,37 %.

Abstract

Analisis kandungan gizi kopi biji salak Desa Pekkabata Kecamatan Duampanua Kabupaten Pinrang bertujuan untuk mengetahui kandungan protein, kadar lemak, dan karbohidrat yang terkandung dalam kopi biji salak produk PKM Badan Kontak Majelis Taklim (BKMT) Desa Pekkabata. Berdasarkan hasil wawancara dan observasi dengan masyarakat setempat, salak hasil panen biasanya dijual ke pasar dan juga biasanya dikonsumsi sendiri, namun biji salak hanya dibuang begitu salak. Dengan demikian tim pengabdi melakukan penyuluhan mengenai pembuatan kopi bijisalak. Berdasarkan hasil analisis diperoleh kadar protein sebesar 4,42%; kadar lemak 12,19%; dan kadar karbohidrat 46,74%.Kata kunci: kopi, biji salak, kandungan gizi. The analysis of the nutritional content of salak seed coffee in Pekkabata Village, Duampanua District, Pinrang Regency aims to determine the protein content, fat content and carbohydrates contained in the zalacca seed coffee products of Community Partnership Program (PKM) BKMT Pekkabata Village. Based on the results of interviews and observations with the local community, the farmed salak is usually sold to the market and is also usually consumed alone, however the zalacca seeds are only thrown away. Thus the PKM team conducted counseling on the making of zalacca seed coffee. Based on the analysis results obtained protein content of 4.42%; fat content 12.19%; and carbohydrate content of 46.74%.Keywords: coffee, salak seed, nutritional content.

Abstract

This research is a quasi-experimental research which aims to know the difference of learning outcomes between the students that learned by using cooperative learning model with type of NHT and the students that learned by using cooperative learning model with type of STAD. The research design was “Posttest-Only Design”. The independent variables of this research are cooperative learning model with type of NHT and cooperative learning model with type of STAD, and the dependent variable is learning outcomes. The population of this research is all first grade students of SMA Negeri 1 Segeri that consist of seven classes with the number 210 students, whereas the research samples are class XH as the first experiment class and class XB as the second experiment class. Each class consists of 30 students. Data of learning outcomes is performed by givingposttest. Data that with multiple choice as much 20 items is analyzed by using descriptive statistics and inferential. The result of analysis shows that the average value of learning outcomes of the first experiment class in the posttest is 77. 16 and the second experiment class is 70.66. The result of hypothesis testing using t-testing isobtained the value as t count = 3.3859 and in the significant level of α = 0.05 with dk = 58 obtained value as t table = 1. 672. Therefore, t count>t table , so that H1 is accepted and H0 is rejected. It means that the learning outcomes of students that learned by using learning cooperative model with type of NHT is better than the students that learned by using learning cooperative model with type of STAD in the fisrt grade class of SMA Negeri 1 Segeri in the main subject of chemical bond.
