Abstract

The research of this background is based on the students understanding of mathematical concepts have minimum level, in pre-teaching,  the teacher do not generate interest of the students and do not give motivation to the students, students tend to be passive and reluctant to ask. The aims of This study is to determine whether students understanding of mathematical concepts by applying the Learning Cycle models are better than student understanding of mathematical concepts by applying conventional learning in class XI students of SMA Negeri 15 Padang. Type of this research is experimental research, the researcher choose the sample of research using Random Subjects . The population of this study was four class of XI IPA students of SMA Negeri 15 Padang academic year 2013/2014. The sample was IPA2 class as the experimental class  and class XI IPA1 as the control class. The Instruments that used in this research is a test of understanding mathematical concepts. Based on the analysis of the data found that the two classes are normally and homogeneous samples at α = 0.05 and the results obtained from testing the hypothesis P-value = 0.007 means less than α = 0.05, so it means that the hypothesis in this study is received . It can be concluded that the students understanding of mathematical concepts that apply the Learning Cycle Model with taped questions better than students understanding of mathematical concepts by applying conventional learning in class XI student of SMA Negeri 15 Padang.

Abstract

AbstrakPenelitian ini bertujuan untuk menganalisis kemacetan di Kota Banda Aceh untuk mengetahui dampak kemacetan terhadap sosial ekonomi masyarakat,penelitian ini menggunakan metode analisis deskriptif kualitatif yaitu untuk menentukan cara mencari, mengumpulkan dan menganalisis data. Data yang digunakan adalah data primer dari 50 responden yang ditentukan melalui random sampling. Jenis data dalam penelitian ini menggunakan data primer dan sekunder yang di hasil dari penelitian ini menunjukkan bahwa kemacetan memberikan dampak yang negatif yang sangat besar bagi masyarakat seperti pemborosan bahan bakar minyak, terbuangnya waktu secara percuma dan kerusakan lingkungan akibat polusi yang dikeluarkan oleh kendaraan bermotor. Kemacetan yang terjadi di kota Banda Aceh itu mencapai 72% sedangkan yang jarang mengalami kemacetan itu hanya 28% dan kemacetan tersebut mengakibatkanstres dan penyebab dari kemacetan itu jelas dapat merugikan masyarakat dan berpengaruh besar terhadap sosial ekonomi masyarakat dan kemacetan terjadi akibat pertambahan jumlah penduduk yang di ikuti oleh pertambahan jumlah kendaraan bermotor. Kata Kunci:   Kemacetan, Jumlah Kendaraan, Jumlah Penduduk, Panjang Jalan, Random Sampling.

Abstract

Likopen atau yang sering disebut sebagai a-carotene adalah suatu pigmen merah terang, suatu fitokimia yang banyak ditemukan dalam buah jambu biji danbuah-buahan lain yang berwarna merah. Jambu biji (Psidium Guajava) adalah salah satu tanaman buah jenis perdu, Jambu memiliki buah yang berwarna hijau (agak kekuningan setelah matang) dengan daging buah berwarna putih atau merah dan berasa asam manis, Jambu biji mengandung vitamin C yang paling tinggi dan cukup mengandung Vitamin A, Kandungan Vitamin C dua kali lipat lebih banyak. Pengaruh waktu terhadap densitas bahwa semakin tinggi waktu yang kita gunakan maka semakin rendah nilai densitas yang diperoleh, karena semakin tinggi suhu yang kita gunakan maka semakin sedikit hasil ekstrak yang didapat, pada run 9 Volume jambu biji 50 ml dan volume n-Heksana 150 ml dengan waktu 110 menit dan suhu yang dipakai 70 oC maka densitas yang diperoleh sebesar 0,397. Kadar likopen semakin banyak larutan yang digunakan maka semakin tinggi pula nilai absorbansi yang didapat pada bahan baku sebanyak 50 ml dengan suhu 70 oC dan pelarut n-Heksana 150 ml, panjang gelombang 470 nm, maka absorbansi yang diperoleh sebesar 0,250 dan kadar likopen yang terekstrak sebesar 6,27.

Abstract

This research is a research development practicum guide in the field of chemistry education. The aims of this research are (1) to obtain a practicum guide based on the Discovery type syntax, (2) the significant difference in the improvement of learning outcomes that are learned using the existing practicum guides at school with the Discovery type practicum guides, (3) the effectiveness of the learning process taught by using the Discovery type practicum guide. using the Discovery type practicum guide. The stages in this research are (1) Syntax analysis of the Discovery learning model to determine the components of the chemical practicum guide according to the Discovery type, (2) Compile and develop a chemical practicum guide on acid-base solution materials according to the Discovery type syntax, (3) Standardization or feasibility test of practicum guides for teacher validators, (4) Implementation of practicum guides for class XI students of SMA Negeri Unggul Sigli, (5) Analyzing the effectiveness of the Discovery type practicum guide in learning Acid-Base Solutions that have been tested. The results of the feasibility test for the Discovery type practicum guide 3.41 and the practicum guide at school 2.31. While the effectiveness of the use of the Discovery type practicum guide and the practicum guide commonly used in schools, judging by student learning outcomes, it is known that the experimental class I which uses the Discovery type practicum guide is an average of 86.00 with an increase in learning outcomes of 71.4% while the experimental class II which uses a practicum guide in the LKS an average of 61.75 with an increase in learning outcomes of 58.8%. So it can be concluded that the Discovery type practicum guide and the practicum guide being studied are feasible to be used as practicum guides in schools, with increased learning outcomes using the Discovery type practicum guide being higher in value than the existing practicum guides in the lectures.Keywords: Development of Practicum Guide, Type of Discovery.

Abstract

This study aims to evaluate the presentation of local financial statements at the Aceh Financial Management Agency office in the context of conformity with the guidelines of Government Accounting Standards (PSAP) 71. Statement of Government Accounting Standards (PSAP 71) regulates local government financial statements, focusing on disclosures related to fixed assets. The evaluation phase includes an assessment of compliance with the standard as well as the quality of the information presented, with a focus on transparency and accountability in asset management. With the existence of PSAP 71, it is expected that financial statements can present relevant, reliable and useful information. This research methodology uses a qualitative approach with data collection techniques. This research was conducted in the time span of 2022-2023. The results showed that although the Regional financial statements in Aceh Province had been prepared with reference to PSAP 71, there were still some discrepancies in the application of accounting principles. For example, it can be in the form of fixed asset valuations that are not updated, so that the reported values do not reflect the actual conditions. Based on the analysis, this study recommends several corrective measures. First, the development of a better and integrated accounting information system to facilitate the process of collecting and presenting financial data.
