Abstract

Ikan lele sangkuriang merupakan salah satu komoditas perikanan air tawar yang banyak dibudidayakan di Indonesia karena permintaan yang terus meningkat. Meningkatnya permintaan ikan lele akan berdampak pada sektor budidaya karena dalam kegiatan budidaya kendala yang dihadapi adalah mahalnya harga pakan dan ketersediaan pakan dalam jumlah yang cukup. Upaya untuk mengurangi biaya pakan, sebagian pembudidaya menggunakan bahan pakan alternatif sebagai pengganti bahan pakan. Lamtoro merupakan sumber daya hayati lokal yang potensial untuk digunakan sebagai pakan dengan dihasilkan limbah hijauan bernilai nutrisi yang cukup tinggi dan mudah dicerna. Penelitian ini bertujuan untuk mengetahui laju pertumbuhan dan kelangsungan hidup ikan lele sangkuriang menggunakan pakan komersial, pakan tepung daun lamtoro dan pakan tepung daun lamtoro fermentasi. Metode yang digunakan adalah rancangan acak lengkap dengan tiga perlakuan dan tiga ulangan. Perlakuan A pakan komersial, B tepung daun lamtoro, C tepung daun lamtoro fermentasi. Parameter yang diukur adalah pertumbuhan berat mutlak, laju pertumbuhan spesifik, kelangsungan hidup dan rasio konversi pakan. Hasil analisis ragam menunjukkan bahwa pemberian pakan yang berbeda signifikan terhadap pertumbuhan berat mutlak, laju pertumbuhan spesifik dan rasio konversi pakan, namun tidak signifikan terhadap kelangsungan hidup ikan lele sangkuriang (Clarias gariepinus var). Pemberian pakan tepung daun lamtoro fermentasi memberikan hasil tertinggi untuk pertumbuhan berat mutlak pertumbuhan spesifik.

Abstract

Cucumber plant (Cucumis sativus L.) is a vegetable plant that has many ingredients which can be used as vegetables, fresh vegetables, salads, or pickles and also cucumber plants can be beneficial for health. Production of cucumber plants in Indonesia from year to year has always decreased. The cause of the low production of cucumber plants in Indonesia is due to several factors, namely environmental factors, cultivation methods and also due to pests and diseases. This study aims to determine and understand the effect of organic and inorganic fertilizers on the growth and production of cucumber plants. The research design used was a randomized block design (RBD) consisting of 5 treatments repeated 3 times, namely 6 kg of goat manure/polybag (P0), 3 kg of goat manure/polybag + 2.5 g of NPK fertilizer/polybag (P1 ), 4.5 kg goat manure/polybag + 1.25 g NPK/polybag (P2), 1.5 kg goat manure/polybag + 3.75 g NPK fertilizer/polybag (P3), 5 g NPK fertilizer/ polybag (P4). The results of the analysis of the variety of application of organic fertilizer at a dose of 6 kg gave optimal results on plant height and number of fruit on cucumber plants but not on the number of leaves, age at the start of flowering, and fruit weight on cucumber plants.

Abstract

Cocoa (Theobroma cacao L.) is one of the people's plantation crops with promising prospects because it can flower and bear fruit throughout the year. One of the efforts to improve the quality of cocoa seeds is by increasing the viability and vigor of seeds through seed invigoration techniques. This study aimed to determine the effect of biopriming invigoration treatment techniques in increasing cocoa seeds' viability, vigor, and growth. This research was conducted at the Laboratory of Agronomy Unit of the Faculty of Agriculture of Halu Oleo Kendari from April to May 2019. This study used a completely randomized design (CRD) consisting of 4 treatments: Control (B0), Bio-priming Bacillus sp. CKD061 (B1), Bio-priming Pseudomonas flourescent (B2), a combination of Bio-priming Bacillus sp. CKD061 with Pseudomonas fluorescent. Each treatment was repeated three times, so there were 12 experimental units. The data obtained were analyzed using variance analysis and continued using the Least Significant Difference Test (LSD). Based on the results of research that biopriming treatment using rhizobacteria has the best influence on the viability, vigor and growth of cocoa seeds. Keywords: Biopriming, cocoa seeds, rhizobacteria, seed growth

Abstract

The obstacle of chilli pepper development in saline is that there is no salinity tolerant variety, so it is necessary to assemble tolerant varieties. Information on tolerant genotypes, selection criteria and determination of new selection methods at the germination level are needed to make it easier for breeders to select prospective tolerant varieties early. This study aims to determine tolerant genotypes, appropriate selection criteria and NaCl concentrations used for selection at the germination level. The study was arranged based on a completely randomized design with two factors: NaCl concentration and some chilli pepper genotypes. NaCl solution concentrations consist of five concentrations of N0: 0 g L-1 (EC 291 µS/cm, SAL 0,10), N1: 2 g L-1 (EC 3,71 ms/cm, SAL 2,0), N2: 4 g L-1(EC 6,60 mS/cm, SAL 3,60), N3: 6 g L-1 (EC 9,56 mS/cm, SAL 5,40) and N4: 8 g L-1 (EC 12,45 mS/cm SAL 5,40). The second factor is the genotype of chilli pepper consisting of 22 genotypes. The results showed that the most tolerant genotypes were G4, G7 and G15. Characters that can be used as selection criteria at the germination level are the percentage of germination, radical and hypocotyl length. The concentration of 8 g NaCl L-1 is effectively used to select tolerant genotypes
