Efektivitas Metode Pemupukan pada Pertumbuhan Dua Varietas Bibit Kelapa Sawit (Elaeis guineensis Jacq.) di Pembibitan Utama (Main Nursery)
No full textTo achieve success in getting the results of plant growth and development, fertilizing is necessary. But before that, palm oil nurseries must be optimized with fertilization for success in planting in the field. The supply of nutrients contained must be able to complement the macro- and micronutrients. Therefore, the accuracy of fertilizer dosage during the nursery process becomes a benchmark and is a very important factor, and the fertilization method is also the right way and the right target in palm oil nurseries in the main nursery. This research was conducted in the nursery area of the Soil Management Field Laboratory of Institut Teknologi Sawit Indonesia, Medan. Soil observations at the Soil, Plant, Fertilizer, and Water Laboratory at the Balai Pengkajian Teknologi Pertanian Johor, North Sumatra, and the Laboratory at the Pusat Penelitian Kelapa Sawit Medan by observing soil analysis on chemical, physical, and exchangeable cation properties, as well as vegetative plant observations in the field, plant fresh and dry weights. The study used a Randomized Group Design where the parameters consisted of plant height, stem circumference, number of leaflets, leaflet length, root and crown fresh weight, and root and crown dry weight. The parameters of plant height, stem circumference, number of leaf midribs, and leaf midrib length have the highest values in the sowing fertilization method, as well as the fresh weight of roots, crowns, and dry weight of roots. Crowns also have the highest value in the sowing fertilization method compared to sachet and drip fertigation. This indicates that the growth and development of palm oil seedlings in the main nursery of PPKS 540 and SP-1 (Dumpy) varieties are better with the sowing fertilization method than the sachet fertilization and drip fertigation methods.154 HalamanTesis Magiste
Analysis of The Occurrence of Damage To Crane Operations on Board Km. Lotus Ungu
No full textThe smooth maintenance and repair of diesel main engines requires complete and adequate equipment. Hoist cranes are equipment used to lift and move engine components that cannot be moved by human labor. With a hoist crane on board, the machinist on board is easier to lift diesel main engine components such as cylinder heads, pistons, and cylinder liners when carrying out maintenance and repairs. To support the process of lifting diesel main engine components during maintenance and repair, the hoist crane must be in good condition. The main point of a good hoist crane is that the hoist crane can lift loads up to 4 tons. The method that the author uses to make this scientific work is to use a qualitative descriptive method. In this scientific work, the instruments used to produce descriptive data are observation, interviews and documentation. Carrying out these steps is expected to find the problems that cause damage to the hoist crane. Hoist crane damage caused by high temperature electromotor can be prevented by performing maintenance according to the planned maintenance system
