Abstract

Sejumlah material sintetis digunakan sebagai inhibitor untuk mencegah korosi, tetapi kebanyakan inhibitor tersebut bersifat racun, maka digunakan bahan organik sebagai inhibitor korosi, yang tidak berbahaya dan ramah lingkungan. Penggunaan inhibitor dikenal sangat baik, diantara beberapa metode pengendalian dan pencegahan korosi. Pada penelitian ini digunakan senyawa kafeina sebagai inhibitor korosi. Senyawa ini dapat digunakan sebagai inhibitor korosi karena adanya gugus-gugus yang mengandung pasangan elektron bebas, yaitu gugus nitrogen. Pengujian laju korosi dilakukan di media air laut yang diambil dari daerah Utara Indramayu dengan variasi konsentrasi kafeina 0, 50, 100, 150, dan 200 ppm untuk mengetahui konsentrasi optimum kafeina dalam menginhibisi laju korosi baja karbon KS01 dan AISI 1045 yang merupakan material yang banyak digunakan pada sistem pendingin di industri. Laju korosi baja karbon KS01 tanpa penggunaan inhibitor lebih kecil, yaitu 25,07 mpy dibandingkan dengan laju korosi baja karbon AISI 1045 yaitu sebesar 45,82 mpy. Hasil penelitian ini menunjukkan bahwa kafeina mampu menginhibisi laju korosi baja karbon KS01 dengan efisiensi optimum sebesar 64,38%, dan baja karbon AISI 1045 sebesar 66,63%. Konsentrasi optimum dari kafeina untuk menghibisi baja karbon AISI 1045 adalah 150 ppm dan untuk AISI KS01 adalah 100 ppm. Selain uji korosi dilakukan juga analisis struktur mikro dari kedua sampel di atas, sebelum dan sesudah diberi inhibitor.

Abstract

KARAKTERISASI  SIFAT LISTRIK GRAFIT SETELAH IRADIASI DENGAN SINAR-g. Telah dilakukan penelitan tentang karakterisasi sifat listrik grafit hasil iradiasi dengan sinar-g. Serbuk grafit dibuat dalam bentuk pelet dengan daya tekan sampai 20 ton. Pada penelitian ini, diamati perubahan sifat listrik grafit setelah diiradiasi dengan sinar-g pada berbagai variasi dosis (100 kGy – 600 kGy). Karakterisasi sifat listrik grafit dilakukan dengan menggunakan alat ukur LCR meter. Hasil pengukuran sifat listrik pelet grafit dengan LCR menunjukkan bahwa nilai konduktivitas dan kapasitansi listrik grafit meningkat akibat radiasi sinar-g, dan nilai ini semakin meningkat seiring dengan bertambahnya dosis radiasi. Peningkatan nilai ini mencapai sekitar 43,2 % untuk nilai konduktivitas dan sekitar 55,4 % untuk nilai kapasitansi setelah diirradiasi dengan sinar-g sampai dosis 600 kGy. Peningkatan nilai ini diperkirakan akibat meningkatnya frekuensi interaksi antara radiasi sinar-g dengan bahan grafit (dalam hal ini adalah elektron), yang menyebabkan daya tampung listriknya meningkat, sehingga sifat listrik bahan grafit tersebut menjadi lebih besar. Kata kunci : Radiasi sinar-g, grafit,  sifat listrik

Abstract

Penelitian ini didasari oleh pentingnya perkembangan dalam kemampuan gerak. kemampuan gerak ini harus ditunjang dengan pembelajaran di sekolah Dilihat dari kemampuan motorik siswa tuna grahita di SDLB Bina Karya Insani Duren Sawit terdapat masalah, terlihat gerakan siswa sangat terbatas ketika melakukan gerak locomotor terutama berjalan, berlari, dan melompat. Seringkali siswa tidak fokus dan bosan ketika melakukan pembelajaran gerak locomotor, sehingga tujuan pembelajaran pun tidak tercapai dengan baik. Peneliti membuat model pembelajaran gerak locomotor berbasis permainan yang bertujuan untuk membuat siswa lebih tertarik dan menciptakan suasana yang menyenangkan bagi siswa tuna grahita dalam melakukan pembelajaran gerak locomotor. Penelitian ini dilakukan dengan mencari informasi, melakukan observasi dan juga wawancara kepada guru terlebih dahulu untuk mengetahui masalah yang ada pada pembelajaran gerak locomotor. maka peneliti membuat 14 model pembelajaran yang layak kemudian divalidasi oleh 2 ahli, masing-masing ahli gerak locomotor dan permainan. Selanjutnya, model pembelajaran ini diujicobakan kepada anak tuna grahita kelas 3 sampai kelas 6 di SDLB Bina Karya Insani Duren Sawit dan teknik analisa data menggunakan validitas ahli. Hasil akhirnya adalah bahwa model pembelajaran gerak lacomotor berbasis permainan layak dan efektif digunakan untuk anak tuna grahita SDLB Bina Karva Insani Duren Sawit.

Abstract

Abstract From the past until now, many parents feel confused and difficult in shaping positive behavior in children. Parents also often feel unable to understand their children's behavior that always tests their patience, so it is not uncommon for parents to become angry and apply punishment to children. This has an impact on the formation of children's perceptions that become negative towards parents. The child will feel that he is not understood, causing him to behave negatively such as lying, not doing his responsibilities at home, and others. One of the efforts that can be made to improve children's positive behavior is for parents to apply effective communication to children in interaction. With this Community Service Activity, it is hoped that it can provide new understanding, knowledge and skills for parents in implementing interpersonal communication with children. Therefore, a warm relationship between parents and children can be established, so that it is followed by positive behavior in children that will also increase. Activities are carried out using the counseling method, namely interpersonal by providing understanding and knowledge related to interpersonal communication so that it becomes a new skill that parents will learn in applying communication when interacting with children. The results of this activity show that parents gain new understanding, knowledge and skills related to applying interpersonal communication when interacting with children. In addition, parents realize that the communication applied so far with children is not appropriate, causing frequent conflicts and having an impact on children's negative behavior.

Abstract

Abstract This community service program aims to enhance digital literacy among the residents of Ngargorejo Village, Ngemplak Subdistrict, Boyolali Regency, by providing training on social media as a tool for promoting the village’s tourism potential. Ngargorejo Village possesses significant tourism potential, including natural beauty, local culture, and distinctive products. However, the community's limited knowledge of social media utilization poses a major challenge in effectively promoting these assets. The training program was designed using a participatory workshop approach, involving ten participants from local tourism managers and small business owners (UMKM). The training materials covered the creation of social media accounts, content development, management strategies, and hands-on practice. Evaluation results indicate a significant improvement in participants’ understanding of social media, with the average pre-test score of 49 increasing to 85 in the post-test. Additionally, the quality of participants uploaded content showed notable improvements in terms of visualization, narrative, and consistency. However, challenges remained, including low initial digital literacy, limited internet infrastructure, and inconsistency in content management after the training. To address these issues, the program provided solutions such as individualized mentoring, structured content guidelines, and the establishment of a village social media management team. This program has successfully provided the community with relevant digital skills, enabling them to independently promote their village’s potential. Recommendations for program sustainability include advanced training, infrastructure improvements, and local government support for regular content management.
