It is also called White Gold. The present investigation was conducted with 52 Gosypium hirsutum entries comprising of 42 F1s produced by Conventional (14 F1s), GMS(14 F1s) and CMS(14 F1s) method, by using same 7 females and 2 males and 1 check were evaluated at three locations viz., Surat, Bharuch and Hansot. The experiment was laid out in a Randomized Complete Block design (RBD) with three replications. Analysis of variance showed significance difference among the characters. The s.c.a. variances were greater than g.c.a. variances for Plant height, number of sympodia per plant, number of monopodia per plant, number of bolls per plant, boll weight, ginning percentage, seed yield per plant, 2.5 per cent span length and fibre length except days to 50 per cent flowering, seeds per boll and seed index, indicating the non-additive gene effects, thus, it emphasizes the use of heterosis breeding approach to exploit available vigour in this crop. The parents, G (B) 20 was found to be good general combiner for all the traits except plant height and ginning percentage and average combiner for days to 50 per cent flowering, seed index and fibre strength, whereas, LRK-516 was found to be good general combiner for all the traits except ginning percentage and average combiner for 2.5 per cent span length and number of bolls per plant. Therefore, these two parents were noted as good source of favorable genes for increasing seed cotton yield through various yield contributing characters.

The need for electrical energy has been dependent on fossil energy, while the availability of fossil energy is decreasing along with the increasing demand for electricity in the community, especially in Siman Village, Lamongan. To overcome this problem, many sources of energy substitutes for fossil energy have been developed and researched in the form of renewable energy sources, one of which is the source of solar energy. One of the applications of solar energy utilization is a solar cell. The proposed solar cell uses Photovoltaic (PV) 1500 WP as energy conversion. PV produces power that is volatile or erratic. So it requires Maximum Power Point Tracking (MPPT) so that PV works at its optimum point. MPPT can find the greatest power from PV using the Perturb and Observe (P&O) algorithm. The converter used is a SEPIC converter which functions to increase or decrease the voltage without changing the polarity of the resulting voltag...

It began to be developed and researched additional energy in the form of renewable energy sources, such as the utilization of solar energy using photovoltaic (PV). The utilization of solar energy in PV can be connected to the grid. For that, we need a stable performance that grid usage can be reduced. So we use Battery Energy Storage (BES). The role of the Energy Management System (EMS) is needed to determine the charge/discharge of battery and strategies to minimize grid power. The proposed research carried out an EMS on a system consisting of PV, BES, and load. First is predicting PV output power using Artificial Neural Network (ANN) by considering the parameters of irradiance, temperature, and time. Second, it is considering battery State-Of-Charge (SOC). The battery is kept at the minimum and maximum SOC limits to maintain the battery. These two parameters become the input of EMS. EMS using ANN to determine charge/discharge of...
