Abstract

ABSTRAK Secara umum penelitian ini bertujuan untuk mengetahui pengaruh adanya beda potenisial listrik dengan berbagai tegangan input di dalam tanah dan lama waktu pemaparan terhadap petumbuhan dari tanaman sawi dengan parameter berupa tinggi tanaman, jumlah daun, kehijauan daun, panjang dan lebar stomata serta berat basah tanaman sawi. Penelitian ini menggunakan 3 kali pengulangan dan 2 faktor, dengan faktor pertama besar tegangan listrik elektroosmosis (1,5V, 3V dan 4,5V) dan faktor kedua lama pemaparan tegangan listrik elektroosmosis (1 jam, 2 jam dan 3 jam). Faktor lingkungan yang meliputi suhu udara, kelembaban udara dan cahaya dikondisikan seragam untuk semua perlakuan. Pemberian pupuk dan penyiraman untuk semua sampel diperlakukan sama. Berdasarkan penelitian dapat diketahui bahwa pemaparan tegangan elektroosmosis dapat mempengaruhi pertumbuhan dari tanaman sawi. Hasil yang didapat juga menyimpulkan bahwa perlakuan tegangan 3 Volt merupakan perlakuan yang terbaik dengan memberikan perbedaan yang nyata. Waktu yang terbaik untuk pemaparan tegangan yaitu selama satu jam untuk parameter jumlah daun, kehijauan daun, panjang dan lebar stomata serta berat basah. Sedangkan untuk parameter tinggi tanaman yaitu selama dua jam. ABSTRACT  In general, this study aimed to determine the effect of electric potential differences with various input voltages in the soil and the length of exposure to mustard plants growth with parameters such as plant height, leaf number, leaf greenery, stomata length and width, and wet weight of mustard plants. This study uses 3 repetitions and 2 factors, with the first factor was electro-osmosis electrical voltage (1.5V, 3V, and 4.5V) and the second factor was the length of electro-osmosis electrical voltage exposure (1 hour, 2 hours, and 3 hours). Environmental factors which include air temperature, humidity and light are uniformly conditioned for all treatments. there was no difference in treatment for water and fertilizer for all plant samples. Based on the research, it can be seen that electro-osmosis voltage exposure can affect the growth of mustard plants. The results obtained also concluded that the 3 Volt voltage is the best treatment by giving a real difference. The best time for stress exposure is one hour for parameters of number of leaves, greenness of leaves, length and width of stomata and wet weight, while for parameters of plant height that is for two hours

Abstract

Marketing strategy has a vital role in increasing sales of "AirKu" products at Perumda Air Minum Tirta Binangun, Kulon Progo Regency. Through the right strategy, Perumda Air Minum Tirta Binangun can be more effective in introducing, promoting, and communicating the value of their products to potential customers. The purpose of this study is to determine how the marketing strategy implemented by Perumda Air Minum Tirta Binangun, Kulon Progo Regency, for AirKu products, and to find out how to formulate an effective marketing strategy. The research method used is a descriptive qualitative method. The population of this study is the marketing unit of AirKu products. The sample in this study is the marketing manager of AirKu products. Data were collected through interviews, observations, and documentation. Data were analyzed using data triangulation, qualitative analysis, and SWOT analysis. The results of this study indicate that the formulation of a new effective marketing strategy is still needed for PERUMDA Tirta Binangun Kulon Progo Drinking Water, namely by utilizing opportunities with a market segmentation approach that is more grouped into types of consumers, overcoming threats is done by monitoring market trends and always adapting to the current market, utilizing the strengths of AirKu products by introducing AirKu products which are local products that are not inferior to other mineral water products. Overcoming weaknesses is done by researching demand from the company's sales partners. This is done to prevent an empty stock of AirKu products at agent, retail, and wholesale partners.
