The beach is an attractive place to unwind from your daily routine. The beauty of the beach must always be maintained so that comfort can still be obtained for everyone who visits it. The beach becomes a comfortable place if cleanliness is maintained. Plastic waste, if any along the coast, can be carried by the waves into the ocean. Plastic waste brought to sea can be consumed by marine biota because marine biota cannot distinguish between plastic and food waste. This community service activity intends to inspire visitors (tourists), managers and traders at Balekambang beach to care about the environment. A well-preserved environment will be a legacy that will be left on the next generation. The survey results show that visitors understand the meaning of waste and are willing to dispose of waste in its place.
ABSTRAKMinyak jelantah merupakan minyak goreng yang digunakan secara berulang-ulang untuk menggoreng makanan dengan menggunakan minyak goreng yang sama. Penggunaan minyak jelantah tersebut menimbulkan bahaya bagi tubuh kita dan pembuangan minyak jelantah secara sembarangan dapat menimbulkan dampak negatif bagi lingkungan maupun perairan. Permasalah ini ditemukan di Desa Bendiljati Wetan Kecamatan Sumbergempol Kabupaten Tulungagung. Tujuan pengabdian kepada masyarakat ini adalah memberikan sosialisasi dan pelatihan (edukasi) kepada ibu-ibu rumah tangga terkait minyak jelantah dan pemanfaatan kembali limbah tersebut. Metode yang digunakan dalam kegiatan ini adalah ceramah dan tanya jawab. Evaluasi dalam kegiatan ini dengan cara membagikan angket berupa pretest dan postest yang dibagikan sebelum dan sesudah kegiatan. Hasil kegiatan ini menunjukkan bahwa penyuluhan dan pelatihan tentang pembuatan lilin dari minyak jelantah telah memberikan informasi dan pengetahuan baru kepada ibu-ibu rumah tangga Desa Bendiljati Wetan. Kegiatan ini telah dapat diikuti dan dilaksanakan dengan baik oleh para peserta.Kata Kunci: Minyak jelantah, lilin, Ibu-ibu rumah tangga ABSTRACT Used cooking oil is cooking oil that is used repeatedly to fry food using the same cooking oil. Using used cooking oil poses a danger to our bodies, and indiscriminate disposal of used cooking oil can harm the environment and waters. This problem was found in Bendiljati Wetan Village, Sumbergempol District, Tulungagung Regency. This community service aims to provide homemakers with socialization and training (education) regarding used cooking oil and the reuse of the waste. The method used in this activity is lecture and question and answer. This activity evaluation by distributing questionnaires in the form of pretest and post-tests shared before and after the action. This activity indicates that counseling and training on making candles from used cooking oil have provided new information and knowledge to homemakers in Bendiljati Wetan Village. This activity has been followed and carried out well by the participants. Keywords: Used cooking oli, candles, homemaker
Material Mg/Al hidrotalsit (Mg/Al-HT-ATBH) terinterkalasi asam 3,4,5-trihidroksibenzoat (ATHB) telah berhasil disintesis dengan metode kopresipitasi langsung melalui mikro reaktor-T. Material hibrida dikarakterisasi dengan XRD dan FT-IR. Hasil penelitian menunjukkan bahwa sintesis Mg/Al-HT-ATBH berlangsung optimum pada pH 8 dengan perbandingan mol ATHB: Mg 2+ : Al 3+ sebesar 0,5 : 2 : 1. Karakterisasi menggunakan FT-IR dan XRD menunjukkan bahwa ATBH terinterkalasi di dalam daerah antar lapis Mg/Al-HT menggantikan anion NO3 -. Hal ini menyebabkan terjadinya pergeseran basal spacing d003 dari 11,27° menjadi 6,74° dan jarak antar lapis meningkat dari 7,84 menjadi 13,10 Å.
ABSTRAK Sudah diselesaikan kegiatan workshop tentang penguatan materi ikatan kimia, penguatan materi kimia koordinasi dan penulisan karya ilmiah pada diskusi bersama musyawarah guru matapelajaran (MGMP) Kimia SMA Kabupaten Malang.
