Abstract

Kelapa Dua Lake is important for the local community as a water catchment and reservoir. At certain times of the year, water hyacinth grown and spread rapidly due to the lake's high nutrient content, including nitrogen, phosphate, and potassium. These are indicators of pollution from the surrounding populated areas. Inappropriate and poorly timed countermeasures against this invasive species have had many negative effects. One countermeasure that could work, however, is harvesting the water hyacinth as a raw material for handicrafts. A joint team of lecturers, UPH service learning, students, a team from the National Disaster Management Agency (BNPB), the Indonesian local government, and local resident carried out a collaborative event to clear one section of Kelapa Lake of both water hyacinth and plastic waste. A numbers of water hyacinth were collected and then processed as a basic material for handicraft products. These handicraft products were then exhibited at an environmental education concert attended by invited guests, including representatives of the Kelapa Dua local government. This event is expected to provide new information about the processing and use of water hyacinth, highlighting its economic value and encouraging more positive activities to decrease water hyacinth and protect the environment.BAHASA INDONESIA ABSTRACT: Danau Kelapa Dua merupakan danau yang sangat penting bagi masyarakat setempat sebagai tempat resapan dan tampungan air. Pertumbuhan eceng gondok di danau ini cukup cepat pada masa waktu tertentu karena adanya kemungkinan air danau yang memiliki kandungan nutrien tinggi seperti nitrogen, fosfat, dan potasium. Oleh sebab itu, invasi eceng gondok pada danau ini menjadi salah satu indikator pencemaran air dari berbagai aktivitas warga di sekitarnya. Penanggulangan yang terlambat dan kurang tepat terhadap invasi eceng gondok memberikan banyak dampak negatif. Salah satu pengontrolan invasi eceng gondok dapat dilakukan dengan memanfaatkannya sebagai bahan baku kerajinan tangan. Kegiatan gotong royong membersihkan eceng gondok dan sampah plastik pada salah satu area danau Kelapa Dua telah dilakukan oleh gabungan tim dosen, service learning UPH, mahasiswa dari berbagai jurusan, tim dari Badan Nasional Penanggulangan Bencana (BNPB), pemerintah dan warga setempat. Setelah kegiatan gotong royong, sejumlah eceng gondok yang dikumpulkan kemudian diolah sebagai bahan dasar produk kerajinan tangan. Berbagai produk kerajinan tangan kemudian dipamerkan pada konser musik edukasi lingkungan. Presentasi produk disaksikan oleh tamu-tamu undangan konser termasuk perwakilan pemerintah daerah Kelapa Dua. Kegiatan ini diharapkan dapat memberikan informasi baru tentang pengolahan eceng gondok agar bernilai ekonomis serta melakukan kegiatan positif untuk menjaga lingkungan.

Abstract

Thromboembolic disorders can cause various life-threatening cardiovascular diseases. Anticoagulants are the most common treatment for thromboembolic disorders. Organosulfur compounds in onions, such as allicin and flavonoid compounds, have anticoagulant properties. The purpose of this study is to test the anticoagulant activity of onions extracted by maceration method using 96% ethanol as a solvent. The anticoagulant test was performed on samples of blood groups A, B, AB, and O using the Lee-White method. Six tubes were filled with 1 cc of each blood sample with treatments including control (without treatment), negative control (96% ethanol), positive control (EDTA), and variation of extract concentrations 5; 7.5; 10%. The results of 96% ethanol extract of Onion (Allium cepa Linnaeus) using the maceration method contains secondary metabolites including flavonoids, saponins, and phenols. The onion extract had a significant mean difference (p < 0.05) with the EDTA positive control group and did not produce a significant mean difference (p > 0.05) with the untreated group, so the onion extract with a concentration of 5; 7.5; 10% extracted with 96% ethanol solvent using maceration method had no anticoagulant activity. Blood type A, B, AB, and O did not have a significant difference in the mean blood clotting time with a value of P = 0.504 (p > 0.05).
