Abstract

Labu Jepang (Kabocha) merupakan tanaman yang berpotensi untuk dijadikan gula glukosa karena memiliki kandungan karbohidrat yang cukup tinggi yakni senilai 13%. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi enzim α-amilase pada hidrolisis enzimatis labu jepang (Kabocha). Penelitian ini dilakukan melalui 4 tahap yakni pelarutan, likuifikasi, sakarifikasi, dan pemucatan. Pada tahap likuifikasi pati diubah menjadi dekstrin oleh enzim   α–amilase dengan kombinasi perlakuan faktorial 3 x 3 yang terdiri dari 3 kali pengulangan pada satu perlakuan variasi konsentrasi enzim 0,01%, 0,02% dan 0,03% berat kering bahan. Analisa kuantitatif gula reduksi diperoleh dengan metode spektrofotometer UV-Vis menggunakan pereaksi Iodium pada panjang gelombang (λ) 348 nm. Hasil yang diperoleh menunjukkan bahwa hidrolisis pati menghasilkan kadar gula reduksi terbaik dengan penggunaan enzim 0,03% berat kering bahan dengan waktu hidrolisis selama 120 menit.

Abstract

This study aimed to determine the results of total tannin content determination of sapodilla peel extract (Manilkara zapota) and the effectiveness of sapodilla peel extract (Manilkara zapota) as a Aedes aegypti mosquito larvicide. The method used was a quantitative descriptive with a purposive sampling method. The sample was ripe sapodilla (Manilkara zapota) peel. The determination of tannin content in sample extracts was analyzed using UV-Vis spectrophotometry. The extraction of tannins from sapodilla peel (Manilkara zapota) was carried out by maceration method using 70 % ethanol. Based on the research results it was found that the total content of sapodilla peel extract was 3,058 mg GAE/g extract. The results of the larvicide test showed that the sapodilla peel extract could be used as an Aedes aegypti larvicide with the most effective concentration in killing 50% of the larvae at a concentration of 20,000 ppm.

Abstract

Plastik merupakan suatu barang yang sangat erat dengan kehidupan manusia sehari-hari dimana memiliki kegunaan dan kekurangan yang apabila terus digunakan akan menjadi salah satu ancaman terbesar bagi kelestarian lingkungan. Permasalahan yang biasa terjadi pada lingkungan kampus yaitu kurangnya keasadaran mahasiswa akan bahaya penggunaan sampah plastik dan belum adanya sosialisasi kepada mahasiswa tentang bagaimana cara pengolahan sampah plastik. Upaya yang dapat dilakukan yaitu dengan pembuatan ecobrick dengan memanfaatkan sampah plastik dan botol minuman. Sasaran pengabdian masyarakat yaitu perwakilan mahasiswa dari lima program studi Fakultas Teknik Universitas PGRI Madiun dengan jumlah 22 orang. Tahap pengabdian masyarakat yaitu tahap persiapan, tahap pelaksanaan dan tahap evaluasi. Instrumen pengukuran yang digunakan yaitu angket pengetahuan sebelum dan sesudah pengabdian, serta angket kepuasan mahasiswa. Kegiatan sosialisasi dan pelatihan pembuatan ecobrick di lingkungan Universitas PGRI Madiun telah mampu meningkatkan pengetahuan mahasiswa dari skor persentase 27% menjadi 86,9%. Mahasiswa juga merasa telah puas atas terselenggaranya kegiatan pengabdian masyarakat ini.

Abstract

The primary source of income for the residents of Kenongorejo Village in Madiun Regency is agriculture. The village is situated in a mountainous region. This village produces an increasing amount of agricultural waste due to the abundance of agricultural products. Environmental pollution may result from the amount of agricultural waste that has not been appropriately recycled. Even if part of the agricultural waste has been used as animal feed, the residents of this village still have a concern with the vast amount that has been wasted. It takes environmentally responsible technologies to transform these agricultural wastes into products with a marketable value. The service team's recommendation is to offer training sessions on the production of eco-enzymes, which source their primary raw material from agricultural waste. In order to improve comprehension and abilities in creating eco-enzymes, the strategy employed in this community service activity includes identifying partner requirements, counselling, training, evaluation, and monitoring, as well as post-activity help. The majority of the women of PKK Kenongorejo Village are the main audience for this project. Eco-enzymes, which can be utilised for domestic requirements and sold to the general public as natural cleaning solutions, are the end products of this service activity.
