One of the causes of low sugar production is the quality of sugar cane seeds. Seed quality is one of the factors that determine the success of sugarcane cultivation. Breeding bud chips is a vegetative sugarcane seedling using one-eye cuttings. In addition to nutrients, growth and seed quality are also influenced by growth regulators (ZPT). Atonic (auxin) is able to increase the metabolic rate so that cell development increases and the absorption area of leaves is more which affects the increase in leaf area, and stimulates plant root growth, increasing root absorption of nutrients. The purpose of the study was to determine the growth response of sugarcane seedlings (Saccharum officinarum L.) on the duration of immersion of cuttings in Atonic PGR solution. The study was carried out using a randomized block design with 4 replications, and 6 levels of immersion time of sugarcane cuttings in Atonik PGR solution: P0 = control, P1 = 10 minutes, P2 = 20 minutes, P3 = 30 minutes, P4 = 40 minutes, and P5 = 50 minutes. Testing the data with an orthogonal polynomial test. Research conclusions: (1) For every 10 minutes of immersion time of sugarcane cuttings in Atonic PGR solution: (a) the length of the sugarcane seeds increased by 0.379 cm, and (b) the dry weight of the sugarcane seeds increased by 0.007 g. (2) The duration of immersion of sugarcane cuttings of one bud in Atonic ZPT solution did not show any effect on the percentage of budding cuttings of sugarcane cuttings, the number of leaves, stem diameter, and wet weight of seedlings. Keywords: Sugarcane Plant Seeds, Soaking Time, ZPT Atonic Solution

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.

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.

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 2022Â 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 = ã€–GAã€—_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.
