Jagung merupakan salah satu komoditas pangan yang penting di Indonesia. Hama utama yang menyerang biji jagung adalah Sitophilus zeamais Motschulsky. Salah satu cara alternatif untuk pengendalian hama S. zeamais yang bersifat ramah lingkungan adalah dengan menggunakan pestisida nabati. Penelitian ini bertujuan untuk mengetahui daya insektisida ekstrak daun jeruk purut dengan formula carrier zeolit sebagai pestisida nabati terhadap hama gudang S. zeamais. Penelitian ini dilaksanakan di Laboratorium Entomologi Seameo Biotrop pada bulan Oktober 2018-Januari 2019. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan tiga kali ulangan pada setiap konsentrasi ekstrak daun jeruk purut yang digunakan. Konsentrasi ekstrak daun jeruk purut yang dipakai pada uji pendahuluan daya insektisida adalah 0%, 6%, 9%, 12%, 15% dan 18%. Konsentrasi ekstrak daun jeruk purut yang dipakai pada uji utama daya insektisida dan uji formulasi adalah 0%, 2%, 4%, 8%, 10% dan 12%. Ekstrak daun jeruk purut pada uji daya insektisida memiliki pengaruh yang nyata sebagai insektisida nabati S. zeamais. Ekstrak daun jeruk purut dalam waktu 72 JSP dapat mematikan hama S. zeamais sebesar 50% (LC 50) dengan konsentrasi 2,03% dan dapat mematikan hama S. zeamais sebesar 95% (LC 95) dengan konsentrasi 10,59%. Formulasi pestisida ekstrak daun jeruk purut dengan carrier zeolit pada 24 JSP, 48 JSP dan 72 JSP memiliki pengaruh yang nyata sebagai insektisida nabati S. zeamais. Pengujian formulasi pestisida dalam waktu 72 JSP belum dapat mematikan hama S. zeamais sebesar 50% (LC 50) dan 95% (LC 95). Hasil penelitian ini menunjukkan bahwa daun jeruk purut lebih berpotensi sebagai insektisida pada komposisi bahan aktif tunggal dibanding formulasi pada hama gudang Sitophilus zeamais Motschulsky.

Kesadaran masyarakat dalam mengkonsumsi sayur dan buah berkualitas saat ini meningkat, tetapi hal tersebut tidak sejalan dengan lahan yang semakin sempit dengan kondisi tanah kurang baik. Hidroponik sebagai alternatif untuk mencukupi kebutuhan masyarakat dalam memperoleh kualitas dan hasil buah. Penelitian ini bertujuan untuk mengetahui produksi dan kualitas melon (Cucumis melo L.) secara hidroponik rakit apung yang diberi nutrisi kalium berbeda. Penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri atas satu faktor yaitu penambahan nutrisi kalium nitrat (KNO3) dan kalium sulfat (K2SO4). Penambahan nutrisi kalium terdiri atas 11 taraf, yaitu K 0%=kontrol tanpa kalium, KNO3 5% = 0,022 g/liter air KNO3 10% = 0,045 g/liter air, KNO3 15% = 0,068 g/liter air, KNO3 30% = 0,136 g/liter air, dan KNO3 50% = 0,227 g/liter air yang berisi taraf kalium nitrat. Taraf K2SO4 5% = 0,003 g/liter air, K2SO4 10% = 0,005 g/liter air, K2SO4 15% = 0,008 g/liter air, K2SO4 30% = 0,015 g/liter air, dan K2SO4 50% = 0,026 g/liter air berisi taraf kalium sulfat. Hasil penelitian menunjukkan aplikasi tambahan kalium melon hidroponik rakit apung tidak memberikan pengaruh yang nyata terhadap semua peubah vegetatif, begitu juga dengan jumlah bunga jantan. Pemberian tambahan kalium berpengaruh nyata terhadap bobot buah, diameter buah, dan tebal daging buah, serta tingkat kemanisan buah. Peningkatan bobot buah, diameter, dan tebal daging buah ditunjukkan oleh perlakuan K2SO4 10% dengan dosis kalium tambahan 0,005 g/liter air. Tingkat kemanisan tertinggi diperoleh dari tanaman melon dengan perlakuan KNO3 50% dengan tingkat kemanisan buah mencapai 18 brix.
