Mining material of quarry (class-C) as one of the activities that utilize natural resources should be able to bringgood impacts to the community economy, but with the understanding of the community that is still said to be low. Some factors such as economic impetus, ignorance aspect, personal interests, political elements, the usage, the quarry brings more negative impact. This is due to the fact thatthere are no clear rules and no boundaries in operatingthe mining process. Reclamation is very difficult to do. The purpose of this research is to explain to the community ofthe dangers posed byquarry to the environment of thecommunity forest at Karang Sidemen Village North Batukliang District, Central Lombok. This research uses qualitative method of research and uses three methods of data collection, namely observation method, interviews, and documentation conducted in the village. This research uses four stages of data analysis, namely data collection, data reduction, display or presentation, and data verification. Theresults show that the understanding of the people about the dangers of class-C mining to the environment of the community forest in the village of Karang Sidemen is still low, due to low education level and based on economic drive factor.

This research aims to describe the learning by applying peer tutor learning model as an effort to improve the learning outcomes in the linear program of fourth semester students in Mathematics education study program of FKIP UM Mataram. The research method used a class action research. The research population was fourth semester students of Mathematics education study program of FKIP UM Mataram, with as many as four students taken as samples. The instruments of the study were the observation results of the learning implementation and the final test result of students study. Analysis of research data on students test results was obtained from the final test result of the learning cycle. The test was said to succeed if 85% of the total students got a value of ≥ 65. Based on the results of the study, the application of peer tutor learning models could improve learning outcomes with the observation result of lecturers and student learning activities were in good criteria. And, the final test score of cycle I had achieved a classical learning standard with a percentage achievement reached 75%.

Abstrak: Pembelajaran yang masih bersifat konvensional menyebabkan siswa merasa kesulitan dalam menyelesaikan masalah dalam setiap materi pembelajaran bentuk aljabar. Akibatnya hasil belajar siswa rendah. Tujuan peneltian ini adalah untuk meningkatkan hasil belajar siswa kelas VII SMP melalui penerapan model pembelajaran TSTS pada pokok bahasan bentuk aljabar. penerapan model pembelajaran TSTS adalah selalu melibatkan siswa dalam setiap penyelesaian masalah dan mencari informasi sendiri karena guru hanya sebagai fasilitator.Subyek pada penelitian ini yaitu kelas VII SMPN 18 Mataram yang terdiri dari 23 siswa. Adapun indikator keberhasilan penelitian ini adalah aktivitas belajar siswa dan guru dikatakan meningkat apabila berkategori baik, serta peningkatan hasil belajar siswa dikatakan meningkat apabila mencapai nilai rata-rata 70 dengan ketuntasan klasikal 75%. Hasil penelitian ini menunjukan terjadi peningkatan hasil belajar siswa dari siklus I sampai Siklus II. Rata-rata hasil belajar siswa pada siklus I 71,01 dengan ketuntasan klasikal 68,56%, sedangkan pada siklus II meningkat menjadi 82,61% dengan rata-rata nilai 76,38. Untuk rata-rata skor aktivitas siswa dan guru adalah 55,76 dan 80,77 yang termasuk berkategori cukup baik dan sangat baik. Kesimpulan penerapan model pembelajaran TSTS pada pokok bahasan bentuk aljabar dapat meningkatkan hasil belajar siswa kelas VII SMP. Abstract:  The convention learning was difficult in teaching aljabar at the students.

Applying of TSTS learning model is followed by the students in problem solving and found out the information by their self because teacher as a facilitator. The subject of research were the students of seventh grade of SMPN 18 Mataram who are 23 students. The indicators of result study were the students learning activities and teacher were improved if it was good and KKM of score was about70, the classical point 75%. The result of study showed the applying cooperative learning TSTS model in teaching aljabar at the students was improved from cycle I until II. The result of score in cycle I 71,01 with classical score 68,56 %, meanwhile in cycle II was improved score 82,61 with mean score 76,38. The result of students and teacher was 55,76 and 80,77, it was included better. The concluded of applying TSTS in teaching aljabar can improved the students ability.

Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas metode pembelajaran Thinking Aloud Pair Problem Solving (TAPPS) terhadap hasil belajar siswa kelas VIII SMP. Jenis penelitian yang digunakan adalah quasi eksperimen dengan melibatkan 42 siswa yang terdiri dari dua kelas dengan teknik purposive sampling. Teknik pengumpulan data dilakukan melalui tes hasil belajar. Teknik analisis data yang dilakukan adalah uji prasyarat analisis dengan uji normalitas, uji homogenitas, dan uji hipotesis dengan uji-t. Berdasarkan analisis data hasil belajar diperoleh rata-rata hasil belajar kelas eksperimen (51,77) lebih tinggi dari pada rata-rata kelas kontrol (39,95). Pada uji normalitas dan homogenitas juga diketahui bahwa kelas eksperimen dan kelas kontrol berdistribusi normal dan homogen. Setelah dilakukan uji-t diperoleh nilai  thitung sebesar 2,33 sedangkan ttabel pada taraf signifikan 0,05 sebesar 1,684. Karena thitung  > ttabel, maka H0 ditolak dan H1 diterima. Jadi, dapat ditarik suatu kesimpulan bahwa  metode Thinking Aloud Pair Problem Solving (TAPPS) efektif terhadap hasil belajar siswa pada pokok bahasan kubus dan balok kelas VIII SMP.Abstract:  This study aims to determine the effectiveness of the Thinking Aloud Pair Problem Solving (TAPPS) learning method on student learning outcomes in class 8 of Junior High School. The type of research used was quasi-experiment involving 42 students consisting of two classes with purposive sampling technique. Data collection techniques are carried out through learning outcomes tests. The data analysis technique performed is an analysis prerequisite test with normality test, homogeneity test, and hypothesis testing with t-test. Based on the analysis of learning outcomes data obtained the average experimental class learning outcomes (51.77) is higher than the control class average (39.95). In the normality and homogeneity test it is also known that the experimental class and the control class are normally distributed and homogeneous. After the t-test is done, the tcount is 2.33 while the t-table is at the significant level of 0.05 is 1.684. Because t count> t table, then H0 is rejected and H1 is accepted. So, a conclusion can be drawn that the Thinking Aloud Pair Problem Solving (TAPPS) method is effective on student learning outcomes on the subject of cubes and beams in class 8 of Junior High School.

Taman Ayu Village in Gerung, West Lombok District, has a prospect as an up-coming tourist area. It is unfortunate if the coastal sand mining activities damage the coastal regions. The research conducted aims to describe the level of understanding and attitude of the community towards the impact of mining illegally. This research method is descriptive, with a qualitative approach by using observation, in-depth interviews. The results of the study show that mining is carried out by the community, because of the need for beach sand for building materials, especially as the final content for making ornaments or home decorations. Coastal sand mining caused a decrease in the beach surface, potential disasters, and coastal abrasion. The positive impact of these activities is increasing the income of the mining community. The community has understood that sand mining activities cause damage to coastal areas, but due to economic demands, the community continues to carry out these activities. In tackling illegal mining on the central coast, the role and responsibility of the Government is integral. Banning and giving warnings in the form of installing warning boards around the mining site as well as providing specialized training for mining officials to provide an understanding to stop the mining activities.
