MENINGKATKAN KETERAMPILAN MOTORIK HALUS MELALUI SENI TARI KREASI BETAWI (Penelitian Tindakan Kelas pada Siswa Tunagrahita Kelas IV Di SDLB C Budi Daya, Cijantung, Jakarta Timur )

Penelitian ini bertujuan untuk mengetahui apakah seni tari kreasi Betawi dapat meningkatkan keterampilan motorik halus siswa tunagrahita kelas IV di SDLB C Budi Daya Cijantung, Jakarta Timur. Penelitian ini dilaksanakan pada bulan Juli hingga November 2011 dengan subyek penelitian siswa kelas IV SLB C Budi Daya Cijantung sebanyak 6 siswa. Penelitian ini dilaksanakan sebanyak 2 siklus. Setiap siklus menggunakan prosedur tindakan yaitu perencanaan tindakan, pelaksanaan tindakan, pengamatan, dan refleksi tindakan. Analisis data dalam penelitian ini menggunakan triangulasi yang didapat dari catatan lapangan, tes unjuk kerja, dokumentasi, dan wawancara. Peneliti menetapkan kriteria ketuntasan minimal adalah memantabkan gerakan motorik halus. Dari hasil tes awal diperoleh bahwa 4 siswa telah mencapai tahap manipulasi gerakan sedangkan 2 siswa masih dalam tahap peniruan berarti masih dibawah ketuntasan minimal yang telah ditetapkan. Setelah dilakukan penelitian tindakan kelas pada akhir siklus II diperoleh data bahwa 4 siswa telah mencapai tahap naturalisasi gerakan-gerakan tari sedangkan 2 siswa telah pada tahap ketetapan gerakan-gerakan tari yang artinya semua siswa telah memenuhi kriteria ketuntasan minimal yang telah ditentukan.Kesimpulan dari hasil penelitian ini adalah bahwa seni tari kreasi dapat meningkatkan keterampilan motorik halus siswa tunagrahita kelas IV di SDLB C Budi Daya Cijantung, Jakarta Timur. This study aimed to determine whether Betawi creation dance can improve fine motor skills in the fourth grade students tunagrahita SDLB C Cijantung Budi Daya, East Jakarta. The research was conducted in July and November 2011 with the fourth grade students study subjects SLB C Cijantung Budi Daya as 6 students. The research was conducted by 2 cycles. Each cycle using the action procedure action planning, action, observation, reflection and action. Data analysis in this study uses triangulation obtained from field notes, test performance, documentation, and interviews. Researchers set a minimum completeness criteria are solidified fine motor movement. From the initial results obtained that 4 students have reached the stage of manipulation movements while 2 students are still in the stage of imitation means still below a predetermined minimum passing grade. After the end of the action research cycle II data showed that 4 students have reached the stage of naturalization dance movements while 2 students have the determination stage dance movements, which means all students have met the minimum criteria that have ditentukan.Kesimpulan completeness of the results of research this is the creation of dance can improve fine motor skills in the fourth grade students tunagrahita SDLB C Cijantung Budi Daya, East Jakarta

Physical Properties of Orange Peels Eco-enzyme: One way to Reduce and Recycle Waste and Environmental Problem

A high quantity of organic waste without proper waste management can endanger public health and environmental sustainability. To reduce the risk that can be caused by organic waste pollution, then there should be a solution. One of them is to make eco-enzyme. Eco-enzyme is a fermented solution from organic waste that can be used as floor cleaner, plant disinfectant, hand sanitiser, plant fertilizer, etc. A good eco-enzyme solution has special properties. One of them is the low-value power of Hydrogen (pH). In this study, other physical properties of eco-enzyme are analyzed. Eco-enzyme was produced from organic waste. Here, Sunkist orange peel and various mixtures of orange peel were used as the main materials of eco-enzyme. The eco-enzyme solutions were carried out for 33 days, accompanied by routine monitoring by reviewing physical parameters such as pH, Total Dissolved Solid (TDS), and Electrical Conductivity (EC) values. The results showed the characteristics of the eco-enzyme product by physical properties are the eco-enzyme has an acidic with a low pH value (1000 ppm) and EC (>1500mS/cm). The finding is TDS and EC have high value whereas usually high EC and TDS are owned by polluted liquids

Resistivity and Density Structure of Limboto Lake—Pentadio, Gorontalo, Indonesia Based on Magnetotelluric and Gravity Data

Limboto Lake—Pentadio area is located in the province of Gorontalo on the northern arm of Sulawesi Island, Indonesia, which experienced a tectonic process from the Sula Platform collision in the mid-Miocene. This tectonic process led to the westward subduction of the early Miocene and post-collision rifting and uplifting of the arc and subduction along the North Sulawesi Trench during the Late Miocene to the Quaternary periods. The rifting process of the North Sulawesi arc resulted in the formation of the Gorontalo graben zone in the W–E direction. There are geothermal surface manifestations near Limboto Lake, such as hot spring complexes, with temperatures ranging from 74.8 °C to 78.5 °C. To understand the geological structure and prospective geothermal characteristics beneath the investigated area, we performed integrated magnetotelluric and gravity surveys. The preferred 3D resistivity model confirmed the presence of a fault system and a graben system that was filled with conductive bodies (~1–15 Ωm) corresponding to alluvium deposits. This result was in accordance with the 2D density model inferred from the gravity data, where a low-density value indicates the presence of a graben zone. The conceptual model of Limboto Lake—Pentadio was constructed using the information from the MT and gravity results, and from the geological study. The conceptual model illustrates the geothermal system in Limboto Lake—Pentadio, which is controlled by the fault system and the Gorontalo graben system
