Abstract

One of the most harmful pests of sugar cane is the Chilo sacchariphagus striped stem borer because it causes a decrease in the quality and quantity of sugar cane. Scratched wounds can be a place of infection of various pathogens so that it can result in fatal losses that can cause the death of sugar cane plants. The purpose of this study was to determine the concentration of tobacco liquid smoke that precisely suppressed the attack of striped stem borer. The study was conducted in the Experimental Garden Sweetener and Fiber Crops Research Institute Malang in May to September 2018. The study was conducted using a randomized block design with 3 replications. The treatments consist of: concentration of tobacco liquid smoke: 10 ml / l, 8 ml / l, 6 ml / l, 4 ml / l, 2 ml / l, Diafentiuron concentration 2 ml / l (negative control), and without treatment. Spraying of liquid tobacco smoke is done every 2 weeks. The results showed that the treatment of tobacco liquid smoke concentration had no significant effect on the intensity of the striped stem borer attack, but the number of sugar cane tillers and sugar content showed a significant effect

Abstract

Permukiman penduduk di RW 07 Kelurahan Merjosari di Kota Malang menghadapi permasalahan pada infrastruktur saluran air di tepi jalan permukiman, menuju riol kota. Limpasan air hujan yang mengalir di atas permukaan jalan, seharusnya dialirkan menuju saluran air kota. Pada kondisi eksisting ruas Jalan Tirto Agung, telah terdapat saluran air memanjang dan melintang, namun kondisinya telah menurun karena debit air hujan lebih besar dibandingkan kapasitas penyalurannya. Kondisi tersebut menyebabkan tepi dan dinding saluran memanjang yang rusak, dan terjadi penumpukan sedimen pada saluran melintang. Pengabdian ini bertujuan untuk memperbaiki dinding saluran drainase memanjang, dan merombak saluran drainase melintang. Kegiatan pengabdian dilakukan dengan pemasangan bata dan plester pada dinding saluran memanjang, dan merubah sudut belok, lebar, dan kedalaman saluran melintang. Rangkaian kegiatan pengabdian diawali dengan persiapan perencanaan dan diskusi dengan warga, dan dilanjutkan dengan pelaksanaan perbaikan yang diikuti oleh Bapak-Bapak Warga RW 07. Hasil kegiatan pengabdian ini berupa saluran air memanjang yang telah diperbaiki dindingnya sepanjang 60 meter. Pada sisi melintang, telah dibangun saluran semi terbuka dengan diameter 40 cm sedalam 60 cm dengan panjang 5 m. Program kegiatan yang dilakukan mendapat respon yang positif yang ditunjukkan dengan antusiasme dan partisipasi masyarakat yang luar biasa dalam pelaksanaan kegiatan. Warga RW 07 Merjosari saat ini telah memiliki saluran air yang lebih memadai, setelah dilakukan perbaikan dinding saluran drainase memanjang dan perombakan saluran drainase melintang pada ruas Jalan Tirto Agung. Permasalahan limpasan air hujan pada ruas jalan tersebut diharapkan tidak terjadi di masa mendatang, karena tepian jalan menjadi lebih tertata dan bantalan dinding saluran air lebih tinggi dari badan jalan

Abstract

The purpose of this study was to study the relationship between storage temperature and sorbitol concentration on the shelf life of strawberries. The research was carried out in the Agrotechnology Laboratory of the Faculty of Agriculture-Animal Husbandry, University of Muhammadiyah Malang in October to November 2018. The design of the experiment used a randomized nested design. The first factor is the storage temperature namely T1 (room temperature) and T2 (cold temperature of 100 C), the second factor is sorbitol concentration which is P0 (without treatment), P1 (5%), P2 (10%), P3 (15%), P4 (20%), P5 (25%), the observed variables were weight loss, fruit volume, fruit hardness, percentage of disease severity, disease attack intensity, fruit shelf life, vitamin C content, and total dissolved solids. The results showed no interaction between storage temperature treatment and sorbitol concentration on the shelf life of strawberries. Temperature of 100 C significantly affected the parameters of weight loss, fruit volume, fruit hardness, percentage of disease severity, intensity of disease attack, vitamin C levels, total dissolved solids, and the shelf life of strawberries. The treatment of sorbitol concentration did not significantly affect the parameters of weight loss, fruit volume, fruit hardness, percentage of disease severity, disease intensity, vitamin C levels, total dissolved solids and shelf life of strawberries. Temperature of 100 C is able to maintain the shelf life of fruit up to 14 days, 25% sorbitol concentration is able to extend the shelf life of strawberries at room temperature for 7 days.
