Abstract

Anak Berkebutuhan Khusus (ABK) memiliki keterbatasan secara fisik, mental, emosi, sosial, dan intelektual, dalam hal ini salah satu yang termasuk sebagai anak berkebutuhan khusus adalah tunagrahita, ini dikarenakan memiliki nilai intelengensia di bawah rata-rata dapat menjadi hambatan bagi mereka sehingga kesulitan untuk memahami materi pada proses pembelajaran terkhususnya matematika. Sehingga diperlukan suatu inovasi yang memiliki tujuan untuk menciptakan media pembelajaran matematika bagi anak tunagrahita dalam mendukung target SDGs 2030 (Sustainable Development Goals) yaitu Smart Book Mathematic for Difabel (SOMABEL) yang harapannya mampu mendukung mereka dalam menghadapi hambatan belajar matematika khususnya materi bangun datar. Metode penelitian yang dipilih adalah Research and Development (R&D), pengumpulan data yang dilakukan dengan studi kasus, studi Pustaka, observasi dan wawancara. Hasil penelitian menunjukkan bahwa media pembelajaran Somabel dapat meningkatkan semangat belajar siswa tunagrahita yang mana media ini secara langsung terintegrasi pada teknologi berbasis website, yang memiliki sekaligus melestarikan budaya Provinsi Bengkulu, serta desain buku dan media fisik yang menarik sehingga tidak membosankan dalam belajar materi matematika. Inovasi media pembelajaran ini juga membantu para guru dalam mengajar guru, karena selain bisa menjadi bahan referensi media ini juga tidak membosankan dan bisa menjadi pengetahuan tambahan untuk pengenalan budaya yang ada di Provinsi Bengkulu. Kata kunci: Pembelajaran Matematika, Research and Development, Website

Abstract

This study aims to determine the content of senggani leaves and utilize senggani leaves as a raw material for printer refill ink. This can increase the utilization of senggani leaves into products that are low in VOC levels. The method used in this study the first test is done, the ink absorption rate test on HVS paper is done by using a medium such as paper by comparing the length of the absorption path ∆x with a time interval t during the absorption process. The next test is the ink performance test using the volume of aqueous solvent and comparing the quality of the ink obtained. The ink consists of 3 components, namely pigment, solvent, and thickening agent the pigment used in this study is carbon obtained from the carbonization of senggani leaves, 98% alcohol is used as a carbon solvent as a thickener and adhesive in the form of gum arabic. The variation of carbon used is 1 gram, 2 grams, and 3 grams, while the volume of aquadest, the volume of alcohol, and gum arabic mass is made fixed that is sequentially 15 mL, 3 mL, and 3.5 grams. The test results of senggani leaf ink with the best composition resulted in solvent and mass variation values by the standard. Meanwhile, from the results of the print test, the resulting printer ink has provided good print and color results as well as commercial ink and does not easily fade if exposed to water. Keywords: senggani leaf, ink, pigment.

Abstract

Statistical Processing Data 2021 shows that technical efficiency in stunting intervention costs in Bengkulu Province always achieves efficient results in the technical system, however, for that reason, it is technically inefficient in costs. This research aims to analyze the Analytical Hierarchy Process (AHP) method in deciding to determine priorities for handling stunting in Bengkulu Province, which will then get results according to the level of needs of each district/city. This study used the AHP method to determine priorities for handling stunting by collecting primary data directly from respondents, namely the Bengkulu Province Health Service. Validity and reliability tests are used before researching to obtain good research results suitable for development. The results of the consistency test showed that the Consistency Ratio (CR) value for each criterion and the alternative was, which means that the filling and results of the questionnaire for respondents had obtained results that met the requirements. The results of the analysis of preferences for criteria/alternatives show that the main priority in making decisions for handling stunting in Bengkulu Province is North Bengkulu as the main priority, followed by South Bengkulu, Seluma, Rejang Lebong, Kepahiang, Central Bengkulu, Bengkulu, Mukomuko, Lebong, and finally Kaur. Keywords: Analytic Hierarchy Process, Consistency Ratio, stunting, Bengkulu Province.
