Abstract

The development of science, technology and art influence on economic and social development of society. The rapid economic growth in Indonesia is still a profit-oriented bussines. The attitude of caring and awareness about the environment tend to be ignored by the employers even do not inserted and properly evaluated in the education curriculum in Indonesia. Attitudes towards environmental awareness needs to be instilled as early as possible to the students and evaluated particularly well in chemistry learning where has direct contact with the environment. The concept of sustainable development issued by the United Nations (UN) could be one of the solution to develop economic with environmental way and can be inserted into chemistry learning process. Sustainable development concept has three main domains are environmental, economic and social. There are several models and strategies of learning where has sustainable development orientation, are: experiental learning, project-based learning, values and character-based learning, inquiry learning, and others. The indicators of the students who have environmental awareness, are: 1) to know and be aware of issues and environmental issues, 2) have a perception and awareness of the issues and problems of the environment, and 3) have confidence in solving environmental problems and contribute to environmental improvement. Writing this article aims to outline the concept of sustainable development in learning chemistry so that it can be a reference for improving students' environmental awareness. This article will examine several issues, are: the concept of sustainable development, learning chemistry for sustainable development, sustainable development-oriented learning models and indicators of environmental awareness. Through this article, educators and stake holders are expected to be able to insert and apply the concept of sustainable development in the learning process chemistry to enhance students' environmental awareness

Abstract

Sirkulasi Perpustakaan Jurusan Administrasi Niaga Politeknik Negeri Ujung Pandang selama ini masih dilakukan secara manual. Oleh karena itu, staff pelayanan perpustakaan sering mengalami masalah dan kendala seperti semakin kompleksnya koleksi perpustakaan, data peminjaman, transaksi dan sirkulasi koleksi perpustakaan yang mengakibatkan seringnya terjadi keterlambatan dalam pelayanan pada anggota perpustakaan dan pembuatan laporan. Penelitian ini bertujuan untuk membuat sebuah program aplikasi pengolahan database perpustakaan yang dapat memberikan kemudahan-kemudahan seperti, kemudahan dalam mengakses informasi mengenai riwayat sebuah buku atau laporan, kemudahan mengakses data-data peminjam atau pengembalian sebuah buku, jumlah buku dan laporan yang tersedia ataupun yang sedang dipinjam, jumlah tambahan buku setiap tahun, dan lain-lain. Kemudahan-kemudahan tersebut terjadi jika menggunakan software/program aplikasi pengolah database yang sesuai, misalnya dengan memanfaatkan MS Access.Tipe penelitian yang digunakan adalah penelitian terapan yaitu salah satu jenis penelitian yang bertujuan untuk memberikan solusi atas permasalahan tertentu secara praktis. Desain penelitian terdiri atas 3 tahapan. Tahapan 1 meliputi ketersediaan data dan informasi, penggunaan perangkat lunak dan keras, serta manajemen yang digunakan. Tahapan kedua adalah penentuan perancangan sistem. Di sini perancangan sistem menggunakan Data Flow Diagram (DFD) sebagai gambaran sistemnya dan ERD sebagai rancangan relasi tabelnya. Perancangan Data Flow Diagram (DFD) dimulai dari pemetaan sistem yang berupa diagram konteks, kemudian membuat DFD level 0, dan dari DVD level 0 dapat dibuat DFD level 1 yang menunjukkan gambaran sistem secara rinci. Sedangkan ERD menjelaskan bagaimana relasi antar tabel dalam suatu database. Tahap ketiga adalah tahap pengujian hasil rancangan sistem.

Abstract

This study aims to determine the ability of snail shell chitosan as an antibacterial on cotton fabric based on the effect of variations in soaking time on growth activity of Staphylococcus aureus. Preparation of chitosan be done in three phases demineralization, deproteination and deacetylation, then chitosan acetate is prepared by dissolving chitosan in a 2% acetic acid solution. The coating of cotton fabric through soaking using sodium periodate is followed by the coating of chitosan acetate with a variation of the soaking time of 1 minute, 5 minutes and 10 minutes. Antibacterial activity test using the stocking method. The results showed that the longer the soaking time, the bacterial growth decreases. It was concluded that chitosan acetate can inhibit the growth activity of Staphylococcus aureus.

Abstract

The objectives of this research were: (1) to prove the influence of strategic quantitative solving problem method in calculating pH of Buffer and Hydrolisis toward the learning outcome of the eleventh grade students of SMA Negeri 2 Palu, (2) to describe the difference between students’ learning outcome which employed Strategic Solving Problem Method (COAST) in solving Buffer soluble pH exercises and Hydrolisis with conventional learning to the eleventh grade students (Science Program) of SMA Negeri 2 Palu. This research employed Design Randomized Control Group Only. The population of the research was the eleventh grade students of SMA Negeri 2 Palu. The sample were classes of Science Program 1 and Science Program 3. The sampling done purposively. The hypothesis examining used t-test statistics test. The research result shows that the students’ learning outcome who employed with COAST method, the average were higher than those who did not. Statistically, there was a significant difference, where tcalculated -4.586 <ttable 2.000, with α significance level = 5% which mean reject Ho and accept Ha. Therefore, it can be concluded that there is a significant difference of the students’ learning outcome employed COAST method in calculating pH and the students’ learning outcome employed conventional one.

Abstract

This study aims to determine the description of scientific attitudes of fourth grade students of SD Inpres Ana Gowa and SD Negeri Buttono K. This research is a survey research with data analysis using descriptive statistics. The population in this study were all fourth grade students of Ana Gowa Inpres Elementary School and SD Negeri Buttono K. The sampling technique used was simple random sampling. The sample in this study were students of class IVB and IVC of SD Inpres Ana Gowa and students of class IVA and IVB of SD Negeri Tombolo K with a total sample of 124 students. Data collection techniques using a scientific attitude questionnaire. The results showed that students' scientific attitudes had the same average score. The indicators of scientific attitudes that had the highest average scores were attitudes prioritizing data or facts with a percentage of 63.50% and the lowest scientific attitude indicator scores were critical thinking attitudes with a percentage of 62.20%. This shows that students' scientific attitudes still need to be developed in the learning process so that it affects cognitive learning outcomes and especially affective learning outcomes in science learning.

Abstract

Creativity is an aspect that is mandated by law and become essential to the development of a nation in order to compete with other nations. The study aimed at examining the correlation between prior knowledge with creative thinking ability of students grade XI IPA at Public Senior high school in entire Takalar district. This study was an ex post facto research. The population was the entire students of grade XI IPA at public senior high school in the entire Takalar which consist of 39 classes with 1537 people. Sample was taken by employing stratified purposive random technique and obtained grade XI IPA 1 students in SMAN 1 Takalar, SMAN 3 Takalar, SMAN 1 Polongbangkeng Selatan, and SMAN 1 Polongbangkeng Utara with 134 students. The instrument of the study used test of prior knowledge consisting of 16 items (α = 0.883) and test of verbal creativity that consist of 18 items (α = 0.808). by using correlation and simple regression analysis, study founded that coefficient correlation between these two variables is 0.619, p = 0.000 (p <0.05). This value indicated that there was correlation between prior knowledge with creative thinking ability in chemistry and the correlation between the two variables is a positive correlation.
