Abstract

[IMPACT OF THE TILLAGE SYSTEM AND OIL PALM EMPTY FRUIT BUNCH MULCH ON GROWTH, YIELD OF SWEET CORN (Zea mays saccharata) AND GROUNDWATER SYSTEM].  This study aims to determine the impact of land management and the use of oil palm empty fruit bunches (TKKS) mulch. This research was conducted from August to October 2018, arranged in a split plot design with two factors. As a first factor, land management consists of unprocessed, plowed, and plowed and harrowed. The treatment of oil palm empty fruit bunches mulch as the second factor consisted of no mulch, 9 tonnes/ha of mulch, 12 tonnes/ha of mulch, and 15 tonnes/ha of mulch. Plant variables observed consisted of plant height, stem diameter, number of leaves, fresh plant weight, plant dry, ear weight, ear length, ear diameter. Soil variables observed were the redistribution of groundwater and infiltration. The results showed no significant interaction between the tillage system and the application of oil palm empty fruit bunch mulch on all observed variables. Treatment without tillage or mulch dose of 12 tons/ha can provide growth and yield of sweet corn plants better than other treatments. The highest water content and infiltration rate were obtained from the dosage of oil palm empty bunches mulch 15 tons/ha. Soil cultivation by plowing and harrowing produces the highest infiltration rate compared to lower tillage intensities. About 18% to 42% of the diversity of growth and yield of sweet corn plants have a significant relationship with the diversity of groundwater.

Abstract

[POD BORER ATTACK ON SIX SOYBEAN VARIETIES AND THEIR EFFECTS ON YIELD]. This study aims to determine the level of pod borer attack on six soybean varieties and their effects on yields. This research was conducted from December 2017 to March 2018 in the Experimental Field of the Faculty of Agriculture, University of Bengkulu, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City. The experimental design used was a Randomized Complete Block Design (RCBD) with the treatment of six soybean varieties (Demas, Argomulyo, Dega, Ringing, Echo, and Dena I) and was repeated 4 times so that there were 24 experimental units. The results showed that the percentage of pod attack on the Demas, Argomulyo, Ringing, Gema, and Dena I varieties was classified as resistant, while the Dega variety was relatively resistant. Whereas the percentage of seed attack in all soybean varieties tested was classified as resistant. Argomulyo varieties have higher resistance to pod borer attack than other varieties because they produce the highest number of trichomes, and the lowest number of larvae per plant. Argomulyo variety produces the highest number of seed weight per plant, and the highest seed weight per plot. The echo variety produces the highest number of total pods, while the Dega variety produces the highest weight of 100 seeds.

Abstract

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND]. This study aims to obtain the precise combination of variety and biofertilizer to increase soybean productivity in Bengkulu coastal land. The research was conducted from March to July 2017, located at Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted using a split-plot design which was repeated three times. The main plot was two soybean varieties (Grobogan and Wilis). The subplots were two types of biofertilizers, arbuscular mycorrhizal fungi and phosphate solubilizing fungi. The result showed that the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) was significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the increment of the Wilis variety (equivalent to 1.12 tons/ha) was higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi showed superior performance than arbuscular mycorrhizal fungi or phosphate solubilizing fungi alone. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). In terms of economics of resources, the use of arbuscular mycorrhizal fungi is not required to be combined with phosphate solubilizing fungi.

Abstract

Abstrak — Permasalahan utama yang dihadapi adalah mengubah budaya masyarakat yang sebelumnya hanya menjual hasil mentah (buah kelapa saja) menjadi budaya agribisnis yang berorientasi mendapatkan nilai tambah atau keuntungan. Produksi kelapa di Desa Kemumu Kabupaten Bengkulu Utara hanya dijual dalam bentuk butir kelapa tanpa sabut. Sementara itu, mengingat besarnya sumber bahan baku dengan harga murah dan tersedianya tenaga kerja, maka kegiatan ini difokuskan untuk memberikan nilai tambah dengan mengintroduksi teknologi pengolahan buah kelapa, sehingga menjadi produk yang bernilai lebih tinggi. Kegiatan pengabdian kepada masyarakat berupa penyuluhan dan praktek tentang pengolahan kelapa menjadi Nata De Coco di masyarakat Desa Kemumu. Bahan baku pembuatan Nata De Coco tersedia di Kemumu sehingga untuk bahan baku tidak perlu mendatangkan dari luar daerah. Kegiatan ini bertujuan untuk memberikan informasi, memotivasi dan meningkatkan pengetahuan masyarakat dalam memanfaatkan potensi lokal daerahnya yang dijadikan produk olahan yang dapat meningkatkan pendapatan. Kegiatan pengabdian ini akan dilaksanakan mulai bulan Mei sampai Agustus 2022, dengan topik khususnya adalah perlunya teknologi pengolahan kelapa menjadi Nata De Coco. Hasil pengabdian masyarakat berupa produk nata De Coco dan perhitungan analisis usaha juga diberikan kepada masyarakat peserta kegiatan sehingga mengetahui keuntungan yang diperoleh untuk membuat usaha pembuatan Nata De Coco. Air kelapa yang semula dianggap limbah dan dapat menjadi polusi apabila dibuang ke lingkungan dapat dicegah dengan mengolahnya menjadi produk fermentasi berupa nata.

Abstract

Tanaman sorgum telah lama dijuluki sebagai tanaman multi guna, sebagai pangan, pakan, pupuk organik, bioethanol, dan herbisida organik. Sorgum digunakan sebagai herbisida organik karena mengandung alelopati. Ekstrak sekunder yang bersumber dari batang ratun sorgum yang mengalami fermentasi satu tahun merupakan hal yang menarik untuk diteliti terkait dampak alelokimia terhadap beberapa varietas test plant (kacang hijau). Tujuan penelitian ini adalah untuk mengetahui potensi ekstrak sekunder batang ratun tanaman sorgum yang mengalami fermentasi satu tahun terhadap penghambatan perkecambahan beberapa varietas test plant. Penelitian dilaksanakan Mei 2023 menggunakan rancangan acak lengkap (RAL). Percobaan uji bioassay disusun faktor tunggal dengan perlakuan berupa beberapa varietas test plant yang diberi aplikasiekstrak sekunder batang sorgum terfermentasi satu tahun. Taraf perlakuan yaitu kontrol (tidak diberi ekstrak) dengan varietas Vima 1, kontrol Vima 2, kontrol Vima 3, kontrol Kutilang, Vima 1, Vima 2, Vima 3, dan Kutilang. Percobaan terdiri dari 3 ulangan dan unit percobaan berupa cawan petri. Setiap cawan petri diberi 10 ml ekstrak air, ditanam 20 benih kacang hijau dan diinkubasi 3 hari. Hasil penelitian menunjukkan bahwa ekstrak sorgum konsentrasi 30% yang terfermentasi satu tahun menghasilkan daya hambat terhadap test plant. Varietas Vima 2 menghasilkan persentase kecambah normal terendah dan abnormal tertinggi. Varietas test plant yang mendapatkan perlakuan ekstrak cenderung mengalami penghambatan, terlihat pada panjang hipokotil, bobot segar hipokotil, persentase kecambah normal maupun abnormal. Selanjutnya disarankan menggunakan test plant kacang hijau varietas Vima 2 karena lebih responsif dan peka terhadap ekstrak.
