    Kontinuasi ke atas dapat digunakan untuk pemisahan anomali gayaberat regional yang dihasilkan dari sumber yang dalam. Dengan menggunakan metode praktis yang berdasarkan pada studi model, ketinggian optimal kontinuasi ke atas untuk pemisahan gayaberat regional-residual dapat diestimasi. Dengan menggunakan metode ini, dapat dihitung ketinggian optimal untuk kontinuasi ke atas. Meskipun secara matematis tidak ada ketinggian optimal, metode ini memberikan prosedur yang obyektif untuk menghitung ketinggian terbaik dari kontinuasi ke atas. Pertama-tama dibuat model sintesis gayaberat 2D dengan menggunakan metode talwani 2D. Model sintesis ini dihasilkan dari anomali benda dekat permukaan (anomali residual) dan anomali dalam (anomali regional). Kontinuasi keatas untuk berbagai ketinggian diterapkan pada model sintesis dengan memanfaatkan konvolusi Fast Fourier Transform (FFT). Untuk menghitung ketinggian optimal kontinuasi ke atas, dilakukan dengan korelasi silang maksimum antara kontinuasi ke atas dari model sintesis dan anomali regional yang diketahui. Sedangkan untuk daerah yang tidak diketahui anomali regionalnya, seperti data lapangan, ketinggian optimum dihitung dari serangkaian korelasi silang antara kontinuasi ke atas pada dua ketinggian secara berturut-turut. Defleksi maksimum ketinggian rata-rata dari nilai-nilai korelasi silang menghasilkan ketinggian optimal untuk pemisahan regional-residual. Metode ini telah berhasil diterapkan pada data model sintesis, yang nantinya akan diterapkan juga pada data gayaberat dilapangan

    Air sebagai komponen dari lingkungan hidup yang akan mempengaruhi dan dipengaruhi oleh komponen lainnya. Semua makhluk hidup membutuhkan air untuk mempertahankan hidup. Namun, dalamkenyataannya air yang berada di badan penerima air TPSA seperti sungai mulai beralih fungsi dan mengalami pencemaran. Penelitian ini bertujaun untuk menganalis akualitas air limbah sampah dan merumuskan beberapa strategi pengendalian pencemaran yang mampu diterapkan dalam kehidupan masyarakat secara berkelanjutan. Lokasi penelitian ini berada di Kampung Ciangir Desa Mugarsari Kecamatan Tamansari Kota Tasikamalaya. Penelitian kualitas air limbah sampah dilakukan melalui wawancara dengan petugas dan masyarakat yang berada disekitar TPSA dan melakukan observasi langsung. Hasil penelitian menunjukkan bahwa air limbah dari penimbunan sampah dapat dikelola menjadi air bersih yang dapat dimanfaatkan oleh masyarakat sekitar untuk sarana irigasi pertanian masyarakat yang melalui beberapa tahapan dengan dibuatnya licit (tempat pengelolaan air sampah TPSA). Air yang telah dikelola melalui licit tidak menimbulkan efek bagi masyrakat. Namun, pada beberapa tahun kebelakang seiring turun hujan yang deras air limbah sampah dari TPSA Ciangir yang merembes ke selokan dan masuk kolam warga, sehingga banyak ikan milik warga mati akibat terkontraminasi air limbah sampah dari TPSA Ciangir tersebut

    Abstract The problem in the mathematics learning process at SD Negeri Panjang 03 Ambarawa is that Critical Thinking and Collaborative skills are still low and have an impact on the students' learning outcomes that have not been satisfactory. Based on these problems it is necessary to conduct classroom action research conducted in two cycles, each cycle consists of five stages: planning, action implementation, observation, evaluation, and reflection. The purpose of this research is to improve Critical Thinking and Collaborative skill through application of Group Investigation model assisted Magic Ball media. The data collection instrument used questionnaires to measure Critical Thinking and Collaborative and observation sheets to obtain data on learning activities. Data analysis techniques using quantitative and comparative descriptive techniques. The results showed that the improvement of Critical Thinking and Collaborative skills was evident from the increase in total score of learners per cycle. Percentage improvement of Critical Thinking skill by 35% in cycle I. After improved the learning design in cycle II succeeded to increase by 64%. The increase also occurred in Collaborative skill, which is 29% in cycle I and 68% in cycle II. Based on the above description it can be concluded that the application of Group Investigation model assisted Magic Ball media is effective in improving Critical Thinking and Collaborative skills.

    Abstrak Tujuan penelitian ini yaitu unutk menganalisis proses implementasi asesmen yang diterapkan untuk anak tunagrahita, menemukan pola perkembangan anak tunagrahita, serta mencari problematika pelaksanaan asesmen di TK LB C1 Dharma Rena Ring Putra. Penelitian ini merupakan penelitian kualitatif dengan metode pengumpulan data observasi, wawancara, dan dokumentasi. Analisis data dilakukan dengan langkah mereduksi data, menyajikan data serta menyimpulkan data. Pemerikasan keabsahan data dilakukan dengan menggunakan triangulasi teknik. Hasil penelitian menunjukan proses pelaksanaan asesmen di TK LB C 1 Drama Rena Ringputra I Yogyakarta dialkukan dengan dua cara yaitu: Pertama, Asesmen perkembangan anak disabilitas, pelaksanan dimulai dengan asesmen prasekolah yang bertujuan untuk mendiskripsikan kemampuan serta hambatan pada anak sebelum masuk sekolah, kemudia dilanjutkan asemen pasca sekolah, sebagai tindak lanjut sesmen pasca sekolah yang bertujuan mengembangkan kemampuan anak dengan mengacu tahapan perkembangan anak disabilitas atau TPPAD (Tingkat Pencapaian Perkembangan Anak Disabilitas). Kedua, Asesmen perkembangan anak tunagrahita dari sudut kenormal, pelaksanan asesmen anak disabilitas dari kenormal dimulai dengan pengamatan setiap hari, pencatatan harian, menganalisa data setiap bulan dan rekap perkembangan selama semester dengan mengacu pada STPPA (Setandar tingkat pencapaian perkembangan anak). Pola perkembangan anak tunagrahrita selalu berkembang berpasang-pasangan, aspek kognitif selalu berpasangan dengan aspek motorik, aspek sosial emosional berpasangan dengan nilai moral agama sedangakan aspek perkembangan bahasa dan seni selalu mengiringi aspek-aspek tersebut. Problem matika pelaksanaan asesmen, masih kurang pahamnya akan pelaksanaan asesmen, kurangnya buku panduan asesmen.   Kata Kunci: Tunagrahita, Asesmen, Perkembangan anak. Abstract The purpose of this study is to analyze the assessment implementation process applied to mentally retarded children, find patterns of development of mentally retarded children, and look for problems in carrying out assessments at TK LB C1 Dharma Rena Ring Putra. This research is a qualitative research with location in SLB C-1 Dharma Rena Ring Putra I Yogyakarta. Data collection is done by observation, interview, and documentation. Data analysis is done by reducing, presenting and concluding data. Data validity is done by using technique triangulation. The results showed the process of conducting the assessment in TK LB C 1 Drama Rena Ringputra I Yogyakarta was conducted in two ways: disabled child development assessment, the implementation begins with a preschool assessment that aims to describe the ability and barriers to the children before entering school, then continued assessment of post-school, as a follow-up post-school assessment that aims to develop and maximize the ability of children by referring to the development stage of children with disability or commonly called TPPAD (Level Achievement of Children Development Disability). Second, the assessment of the development of the intellectual disability children from the normal point, the implementation of the child's assessment of disability from the normality begins with daily observation, daily recording, analyzing data every month and recap the progress during the semester. The process of implementing the child's assessment of intellectual disability from the angle of normality refers to STPPA (Standard level of child development achievement).. Pattern development of intellectual disability children always develop in pairs, cognitive aspect always pairs with motor aspect, emotional social aspect paired with religion moral value while the aspect of language development and art always accompany those aspects. Problematic implementation of the assessment is the absence of assessment standards and appraisal books for intellectual disability children.
