Eksplorasi Tekstur Tiga Dimensional Dengan Aksara Sunda Baku Sebagai Inspirasi Visual Pada Produk Fashion

Aksara Sunda merupakan sistem penulisan yang pertama kali digunakan oleh sebagian rakyat Sunda pada Abad XIV-XVIII, dimana aksaratersebut merupakan perkembangan dari Aksara Pallawa yang telah mencapai taraf modifikasi bentuk khasnya sebagaimana yang digunakan naskahnaskahlontar pada Abad XVI. Pada awal tahun 2000-an pemerintah Jawa Barat melakukan modifikasi dan pembaharuan pada Aksara Sunda agarlebih sesuai dengan perkembangan zaman, yang kemudian lebih dikenal dengan Aksara Sunda Baku. Namun demikian perlu diperhatikan bahwakeberadaan Aksara Sunda tidak pernah menonjol di dalam kehidupan masyarakat Sunda, dimana bahkan masyarakat Sunda sendiri justru lebihmengenal Hanacaraka yang sebetulnya berasal dari Jawa sebagai Aksara Sunda yang asli. Upaya pemerintah Jawa Barat untuk mengenalkan kembaliAksara Sunda Baku sendiri dirasa tidak memenuhi sasaran, karena walaupun dijadikan pelajaran pada muatan lokal, signage jalanan di kota Bandung,dan nama kantor-kantor pemerintahan Jawa Barat, masyarakat awam sendiri akan lebih memedulikan keberadaan huruf latin yang disandingkanbersama Aksara Sunda. Pembelajaran ini bertujuan untuk membuat masyarakat menyadari kembali akan potensi Aksara Sunda Baku, paling tidakmembuat mereka mengenali bahwa Aksara Sunda memiliki karakterisasi tersendiri yang berbeda dengan Aksara lainnya. Untuk membuat dampakyang lebih besar, eksplorasi tekstur tiga dimensional digunakan untuk memvisualisasikan motif Aksara Sunda Baku dan menjadikannya produkfashion. Penilitan ini diharapkan dapat menjadi langkah awal untuk penelitian lebih lanjut mengenai potensi Aksara nusantara

The main objective of teacher training is to improve the ability and skills in learning process, so as to prepare students for competition in the millennial century. In chemistry learning teachers must be able to stimulate all initiatives, creativity and scientific attitudes through guided inquiry-based laboratory activities. The purpose of this study was to measure the effectiveness of teacher training in improving the ability to develop guided inquiry lab worksheets to achieve students’ understanding and literacy. The training involved 26 chemistry teachers who teach in Karawang West Java. The method applied in this study is multi-method, both quantitative and qualitative with multi-design. The results achieved in this study indicate that the teacher’s response to training materials and training methods is very strong based on the results of the pretest and posttest. Increased ability of teachers in inquiry is classified as medium category. In general, the teacher’s response to the training showed a very positive response especially to the topic of practical evaluation or evaluation. Some teachers demonstrated their ability to design guided inquiry-based lab worksheets mainly related to contextual phenomena, including the effect of vinegar acid concentration on baking soda decomposition reactions, and the effect of fertilizer concentrations on grain sprout growth Teacher training is still a project that many considered as not effective and has a number of shortcomings. Learning should prepare students according to the demands of the 21st century. So that the learning process of chemistry should stimulate initiative, creativity, and scientific attitude through Guided-Inquiry based laboratory activity to improve student literacy ability. The objective of this research is to measure the effectiveness of teacher training in improving the production ability of Guided-inquiry Labs to achieve students’ understanding and literacy. The training involved 26 chemistry teachers as trainees, a mixed method chosen to measure the quantitative side by preexperimental design with a pretest-posttest design, one-group design and teacher feedback collection on training through questionnaires. The pretest and posttest results were calculated by measuring N-gain, and scoring teacher responses on a scale of 1-4. The results of questionnaire showed that the teachers responded with strong criteria and very strong, with an average of 83 (Very Strong). Increased ability of participants is shown with N-gain obtained by each teacher. The average N-gain of trainees is 0.71 in the medium category. Aspects of analyzing the curriculum have the smallest N-gain value compare to the aspects of composing the referring questions and aspects of presenting the experimental data in the form of tables/graphs. In general, teachers’ responses to training show very strong categories with the highest responses on the topic of practicum assessment. And the ability of teachers in designing guided-inquiry self-study worksheets has improved especially for aspects of curriculum analysis and presenting experimental data in the form of tables/graphs. The development of teachers’ skills through measurable training that focused on improving teacher competence should be more frequent. The selection of materials that are urgently needed and used in the learning process should also be considered.     Keywords: guided inquiry, LKS, rate of reaction, student worksheet, scientific literacy, training, scaffoldin

Increasing Nitrogen Fertilizer Efficiency on Wetland Rice by Using Humic Acid

The objective of the research was to study the interaction between dose of humic acid and nitrogen fertilizer on the growth and yield of  rice. The experiment was conducted in May until September 2014 in Sukamanah village Cipedes sub-district Tasikmalaya city. A field experiment was done using as split plot design consisted of two factors. The dosage of humic acid were placed as main plot consisted of four levels i.e. 0 kg ha-1, 3 kg ha-1, 4 kg ha-1, and 5 kg ha-1; and the rate of N fertilizer, as subplot, consisted of 4 levels i.e.0 kg N ha-1, 45 kg  N ha-1, 67.5 kg  N ha-1, and 90 kg N ha-1. The variables observed were: (a) the levels of soil organic C before and after treatment, (b) the levels of crop N, and (c) the components of growth and yield. Nitrogen fertilizer efficiency was expressed in terms of  agronomic efficiency of nitrogen (AEN). The results showed that the growth and yield of rice given humic acid was higher than that without humi cacid. The increasing dose of humic acid i.e. 3 kg ha-1, 4 kg ha-1, and 5 kg ha-1 did not have significant effect. A higher response on growth and grain yield was shown at the dose of humic acid 3 kg ha-1. Nitrogen fertilizer gave significant effect on all growth variables and yield of rice. The higher the level of nitrogen fertilizer up to a certain level (i.e. 67.5 kg N ha-1 or equals to 150 kg  Urea ha-1), the higher would be the effect on all growth variables and yield. The increase in weight of grain ha-1 due to the increased level of nitrogen fertilizer compared to those without nitrogen fertilizer (control) were respectively 58.05% at 45 kgha-1 N, 150.54% at 67.5 kg  ha-1 N, and 168.13% at 90 kg ha-1 N. Humic acid increased the efficiency of N fertilizer. The most efficient dose of N fertilizer was 67 kg ha-1, equal to 150 kg ha-1 combined with humic acid 3 kg ha-1.
