Abstractâ€” The percentage of failure to multiply "Siam madu" oranges by grafting in the rainy season is around 50 % to 80 %. The purpose of the study was to determine the interaction of rootstock pruning length and time of grafting plastic opening on the initial growth ofÂ "Siam madu" oranges (Citrus nobilis L). The study used a factorial experiment based on a randomized block design (RAK). The first factor was the length of pruning (P) were, P1 = 5 cm above of patch eye with 0.5 stems, P2 = 5 cm above of patch eye, and P3 = 10 cm from the shoot. The second factor is the opening time of grafting plastic (B) were B1 = 25 days after grafting (DAG), B2 = 30 DAG and B3 = 35 DAG. Observation parameters included the percentage of grafting growth, time of shoot appearance, number of leaves, length of grafting shoots, and leaf area. The results showed that there was a significant interaction between the treatment of rootstock pruning length (P) and plastic opening time (B) to shoot appearance time, the number of leaves, shoot length, and leaf area. The best results of the combination variable treatment observed were achieved by the treatment of rootstock pruning length of 5 cm above of patch eye and opening time of grafting plastic 25 DAG (P2B1), namely shoot emergence time (30.20 days), shoot length 46 DAG (21.06 cm). In addition, the number of leaves was 46 DAG (10.66) and leaf area (225.96 mm2)Â Keywordsâ€”: grafting percentage growing;; root stock; scions; vegetative propagation

Abstractâ€” Rice is the staple foodstuff in Indonesia, rice consumption in Indonesia has increased every year. The obstacle found in rice production centers is the scarcity of labor, which has become a barrier to rice farming, especially the labor for planting rice seeds. The limited number of workers when planting rice seeds causes the rice planting schedule to not be synchronized. So there needs to be a change in rice farming, one of which is by means of a rice planting system using a rice planting machine, because rice planting machines do not require a lot of labor. Apart from having less labor, the use of rice planting machines also reduces costs. The method used is descriptive, namely research that leads to the disclosure of a problem or situation as it is. The method used is Î = TR-TC (Î = farm profits) TR = total revenue, and TC = total production costs consisting of fixed costs and variable costs. The results showed that the R / C ratio of rice farming with the machine cropping system was feasible to develop with an R / C ratio of 2.25.Â Keywordsâ€”: Farming Analysis; Rice Plants; Rice Transplanter.

The natural growth period of porang plants is only about four months in a year, allowing them to be planted in the off-season. For this purpose, the availability of seeds is a problem that needs to be solved. One technique that can be used to produce porang seedlings out of season and does not take long is the tissue culture technique. This technique has the advantage of using selected lines, free of pests and diseases, and can produce many seeds quickly. However, the problem that often occurs is its sensitivity to disease contamination during the culture-making process. Laboratory quantitative research in the form of experiments using an empirical approach is used in this study. The treatments used were the use of implant origin, namely: (1)upper tuber shoots, (2) bottom tuber shoots, and (3 )buttom tuber skin shoots. The callus formation in this experiment was still low due to the high level of fungal contamination. Estimated that the fungus carried out by the origin of the tubers and laboratory conditions are less sterile. Porang plant tissue culture should use specially grown shoots that are free of pests and diseases. Keywords—: upper tuber shoots, buttom tuber shoots, tissue culture, “porang”
