Abstract

Patchouli (Pogostemon cablin Benth.) is one of the essential oil-producing plants which is Indonesia's leading export commodity so that it can contribute foreign exchange for the country. Patchouli production nationally is still fluctuating and the productivity of patchouli oil is still relatively low. Therefore, proper patchouli cultivation techniques are needed. Plant distance is an important factor in determining the quality and quantity of production. In addition, the use of superior varieties is also a technology that aims to increase the productivity, yield and quality of patchouli oil. This study aims to determine the interaction and analyze the growth and yield of three varieties of patchouli (Pogostemon cablin Benth.) at different plant distance. This research was conducted in October 2021 – March 2022 at the Experimental Garden of Agrotechno Park, Universitas Brawijaya, Jatikerto Village, Kromengan, Malang, East Java. The tools and materials used in this study were tractors, ovens, LAM, scales, hoses, alphaboard, polybags, stationery, cameras, patchouli seeds of Sidikalang variety, Patchoulina 1 variety, Patchoulina 2 variety, planting media, rainfall data, manure, fertilizer. Urea, KCL fertilizer, SP36 fertilizer, raffia rope and water. The design used in this study was the Randomized Block Design which was arranged in a factorial manner consisting of 6 treatment combinations and 4 replications, namely: V1J1: Sidikalang variety + 75 cm x 40 cm plant distance; V1J2: Sidikalang variety + 60 cm x 50 cm plant distance; V2J1: Patchoulina 1 + plant distance 75 cm x 40 cm; V2J2: Patchoulina 1 variety + 60 cm x 50 cm plant distance; V3J1: Patchoulina 2 variety + 75 cm x 40 cm plant distance; V3J2: Patchoulina 2 variety + 60 cm x 50 cm plant distance. The results showed that the treatment of varieties and plant distance had a significant effect on the components of patchouli plant growth. While the yield component of patchouli shows the interaction between varieties and plant distance. The conclusion of this study is that there is an interaction between the treatment of varieties and plant distance on the increase in fresh weight, dry weight and productivity of patchouli. The Sidikalang variety with a plant distance of 60 × 50 cm had the highest yield and oil quality compared to other treatments. The Sidikalang variety also had the highest growth compared to the Patchoulina 1 and Patchoulina 2 varieties. Likewise, the 60 cm x 50 cm plant distance treatment had the highest growth compared to the 75 cm x 40 cm plant distance.

Abstract

The presence of weeds in rubber plantations causes a decrease in productivity so it needs to be controlled. An effective and efficient method on a broad scale in terms of cost and time to control weeds is the chemical method using herbicides. One of the active ingredients of herbicides that can control rubber plantation weeds is paraquat dichloride. The purpose of this study was to determine the effective dose of paraquat dichloride in controlling rubber plantation weeds. This study used a randomized group design (RAK) with 6 treatments and 4 replications. The treatments consisted of herbicide application of paraquat dichloride at a dose of 310.5 g ha-1 (P1); 414 g ha-1 (P2); 496.8 g ha-1 (P3); 621 g ha-1 (P4), mechanical (P5), and control (P6). The results showed that: (1) paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 effectively controlled total weeds and weeds per class; (2) paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 resulted in changes in weed composition at 4-12 MSA; (3) application of paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 did not cause poisoning in rubber plants.

Abstract

Pestisida adalah zat khusus untuk memberantas, mencegah atau membasmi gangguan serangga, binatang pengerat, nematoda, cendawan, gulma, virus, bakteri, jasad renik yang dianggap hama yang merugikan. Penggunaan pestisida yang berlebihan dapat menyebabkan resistensi hama, resurjensi hama, munculnya hama sekunder, dan pencemaran lingkungan. Penelitian ini bertujuan untuk melakukan evaluasi penggunaan pestisida oleh petani dalam mengendalikan hama dan penyakit pada pertanaman hortikultura di Kabupaten Bangka, Provinsi Kepulauan Bangka Belitung. Penelitian ini disusun berdasarkan wawancara dan hasil observasi pada lahan pertanaman petani hortikultura. Hasil yang didapatkan dari wawancara dan observasi tersebut menunjukkan bahwa petani masih banyak menggunakan pestisida sintetik dengan tidak bijak dalam mengendalikan hama dan penyakit tanaman yang dibudidayakan. Dalam penggunaan pestisida, petani masih mengandalkan pengalaman pribadinya dibandingkan dengan ilmu pengetahuan. Rata-rata petani belum memahami penggunaan pestisida yang baik dan benar sehingga tidak mengerti mengenai ambang ekonomi dalam menggunakan pestisida. Kesimpulannya, petani masih beranggapan bahwa semakin banyak jenis pestisida yang digunakan, maka semakin cepat untuk mengendalikan hama dan penyakit tanaman. Dengan demikian, perlu adanya penyuluhan tentang penggunaan pestisida pada petani, sehingga petani dapat memahami cara penggunaan pestisida dengan bijak untuk kedepannya. Spesies hama dan penyakit yang menyerang tanaman hortikultura yaitu, 13 spesies hama dan 11 spesies penyakit.

Abstract

Soybean imports in Indonesia show that national soybean production is still low and efforts are needed to increase production. One way to increase edamame production is the application of Trichoderma sp. and NPK fertilizers. The purpose of this study is to determine the effect of the application dose of Trichoderma sp. and NPK fertilizers and their combinations on the growth and yield of soybean plants. This study used a factorial Randomized Block Design (RBD) consisting of two factors, namely Trichoderma sp and doses of NPK fertilizer, repeated 3 times so that there were 30 experimental units. The treatment consisted of: factors (a) Trichoderma sp. dose: a0= 0 g/plant; a1= 5 g/plant; a2= 10 g/plant; a3= 15 g/plant; and a4 = 20 g/plant. Factor (b) NPK fertilizer dosage from 2 levels, namely: b1 = 250 kg/ha and b2 = 300 kg/ha. The results of this study are: (1) administration of Trichoderma sp. independently affects the growth observation variable in the vegetative phase of the plant, but does not significantly affect production; (2) NPK fertilizer independently affects plant growth in the vegetative phase and production yields; (3) combination treatment of Trichoderma sp. 15 g/plant and 250 kg/ha of NPK fertilizer gave the highest seed weight per plant, namely 30.95 g; and (4) there is an interaction effect between the Trichoderma sp. treatments. and NPK fertilizer on seed weight per plant.

Abstract

One of the essential factors in edamame soybeans production is the use of quality soybean seed. Quality seeds had high viability and vigor values. One of the problems faced in the supply of quality seeds is seed deterioration. Seed deterioration is a process of decreasing seed vigor and viability during storage. Priming is a seed invigoration technique which is a process that controls the hydration-dehydration of seeds for metabolic processes to take place before germination. This objective was to determine the effect of priming media on the viability and vigor of edamame soybean seeds. This study was carried out from November 2021 to January 2022  in the Seed Technology Study Program greenhouse, Politeknik Negeri Lampung. This study used a factorial Completely Randomized Design (CRD) consisting of two treatment factors. The first factor consisted of four soaking media, specifically K1 = Aquadest, K2 = 〖GA〗_3, K3 = coconut water, and K4 = Atonik. The second factor is soaking time (L), which consists of L1 = 4 hours, L2 = 8 hours, and L3 = 12 hours. The observed variables in this study were germination, vigor index, maximum growth potential, growth simultaneity, growth speed, and root length. The interaction between priming treatment and soaking time had a very significant effect on the germination rate (DB), maximum growth potential (PTM), and growth simultaneity (KST). Meanwhile, the growth speed (KCT), vigor index (IV), and root length (PA) had no significant effect. The best invigoration priming treatment is coconut water as a medium with a soaking time of 12 hours which has the highest value.

Abstract

Soybean seeds are stored before being planted in the field, during this storage period the seeds can experience deterioration, if not stored in appropriate environmental conditions, seed deterioration will occur more quickly and can reduce the physiological quality of the seeds. The research aims to determine the physiological quality of gamma-ray irradiated black soybean seeds during the storage period. This study used a non-factorial completely randomized design , with control/no irradiation treatment of 0 Gy (R0) and 5 doses of gamma irradiation, including: 50 Gy (R1), 100 Gy (R2), 150 Gy (R3), 200 Gy (R4), 250 Gy (R5), each treatment was repeated four times. The variables observed were electrical conductivity test, seed germination, growing district, germination height, vigor index, and growing simultaneity. The results showed that the higher the dose of irradiation, the lower the percentage of seed germination, and the lower the physiological quality. Key word: Seed storage, Black soybean, Irradiation

Abstract

Sunflower seeds are the second largest producer of vegetable oil in the world. Sunflower seeds production ranks third in the world after peanuts and soybeans. Efforts to increase sunflower growth are through cultivation techniques including fertilization with the right dosage and treatment in the form of defoliation. Defoliation aims to increase the intensity of sunlight that can be received by plants, so that it will increase crop yields. Decreasing the intensity of sunlight can reduce yields by 40%. This research was conducted using the experimental method which was arranged in a factorial manner in a Completely Randomized Block Design. The first factor was the Professional NPK dose which consisted of two levels including the recommended dose (P1) and half the suggested dose (P2). The second factor is defoliation time which consists of three levels including phase R1, phase R2, and phase R3. The number of leaves removed is 30% of the number of leaves. The results showed that (1) the half recommended dose of NPK Professional in phase R3 had an effect on the variables of plant height and number of leaves and the recommended dose of Professional NPK had an effect on stem fresh weight; (2) The recommended dose of Professional NPK effects the variables of stem diameter and flower diameter in R2 phase, the recommended dose of Professional NPK affects root dry weight in R2 phase, and the weight of 100 seeds in R1 phase. (3) There is an interaction between the dosage of NPK Professional and defoliation time of sunflower plants. Keywords : Sunflower, NPK, Defoliation
