Abstract

Dalam menganalisis kemampuan lahan selalu menggunakan data keruangan. Data tersebut merupakan data faktor yang akan menentukan satuan kemampuan lahan diantaranya jenis morfologi, kestabilan lereng, kedalaman efektif dan ketersediaan air. Data lingkungan tersebut ditumpang-susunkan dan diberi nilai untuk mendapatkan kelas kemampuan lahan sesuai potensinya. Tujuan penelitian ini menentukan kemampuan lahan, membandingkan penggunaan lahan dan merekomendasikan pengembangan sesuai kemampuan lahan di wilayah Kabupaten Musi Rawas Provinsi Sumatera Selatan. Pengolahan data pada satuan kemampuan lahan dilakukan dengan pemodelan spasial menggunakan sistem informasi geospasial yaitu dengan metode tumpang susun (overlay). Hasil analisis kelas kemampuan lahan terdiri dari 3 kelas kemampuan lahan yaitu kelas kemampuan lahan b dengan klasifikasi pengembangan rendah dan diarahkan untuk tetap dilestarikan dan tidak merusak tutupan lahannya. Kelas kemampuan lahan c dengan klasifikasi pengembangan sedang, arahan pengembangan harus mendapat persetujuaan telaah tata ruang. Pada kelas kemampuan lahan d dengan klasifikasi pengembangan agak tinggi yang mempunyai sedikit penghambat perlu perhatian terutama pada lahan sawah, sungai, danau dan rawa agar tidak dialih fungsikan, sedangkan kawasan rawan banjir tidak ada pembangunan. Pada rentang waktu antara tahun 2008 ke tahun 2017, ternyata ada perubahan luasan kemampuan lahan. Pada tahun 2008 luasan kemampuan pengembangan agak tinggi seluas 53,17%, dan pada tahun 2017 menjadi seluas 53,39%. Untuk kemampuan pengembangan sedang, pada tahun 2008 seluas 44,92%, menjadi seluas45,72% pada tahun 2017. Dengan kurun waktu yang sama pada tahun 2008 kemampuan lahan rendah seluas 1,91% dan pada tahun 2017 menjadi seluas 0,89%.

Abstract

[GROWTH AND YIELD OF  EIGHT SWEET CORN GENOTIPE ORGANICALLY GROWN IN SWAMPLAND]. Sweet corn (Zea mays saccharata Sturt) has a greater advantage than feed corn because of its early maturity and the price is more expensive. Recently, the need for sweet corn is higher than its production. To overcome these problems, it is necessary to expand the planting area by utilizing sub-optimal land such as swamps of low fertility. Agricultural intensification can be carried out through the use of organic materials to meet nutrient needs for growth and yield of sweet corn. Determination of varieties suitable for planting in sub-optimal land is also an effort to increase the productivity of sweet corn in swampland. This study aims to determine the potential of sweet corn genotype for organically cultivated in swampland. The material used in this study consisted of seven sweet corn genotypes and one comparative variety planted in experimental plots based on a Randomized Completely Block Design (RCBD) with three replications. The variables evaluated in this study were the growth, development, yield, and yield components of sweet corn. The results showed that the 8 sweet corn genotypes tested had significantly different in plant height, number of leaves, number of rows of seeds per cob, and yields per plot. Caps 17 B x Caps 22 and Caps 3 x Caps 5 are genotypes that have better growth than the comparative variety. On the other hand, the yield and yield components of the comparative variety was higher among the other genotypes tested.

Abstract

[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.
