Abstract

Letak astronomis Indonesia yang dilewati oleh garis khatulistiwa memberikan potensi yang sangat baik dari sumber energi surya, sumber energi ini dapat dimanfaatkan dalam berbagai aspek kehidupan salah satunya untuk daur ulang air kotor. Indonesia sebagai negara maritim yang memiliki luas daerah perairan sekitar 62,89 % luas Indonesia, tetapi hal ini tidak menjamin banyaknya sumber air bersih yang merata disetiap daerah. Alat daur ulang air kotor tenaga surya dirancang untuk menghasilkan air bersih, dengan memanfaatkan radiasi matahari yang diserap oleh kolektor pelat datar maka akan membantu proses penguapan air kotor yang diletakkan dalam bejana tepat di atas kolektor, sehingga akan menghasilkan uap air dan terkondensasi membentuk butir-butir air (kondensat) yang menempel pada permukaan penutup alat yang terbuat dari kaca sehingga dapat dialirkan ke penyimpanan air yang sudah bersih. Volume air bersih rata-rata yang dihasilkan setiap jam adalah 217,5 ml dengan suhu sekitar 37,2 oC dan intensitas cahaya matahari yang mengenai tutup kaca sebesar 350 Cd. Air bersih yang dihasilkan ini tidak dapat dikonsumsi langsung oleh tubuh manusia dan perlu diolah lebih lanjut dengan proses kimia. Kata kunci: Daur ulang air, Tenaga surya, Kolektor pelat datar.

Abstract

Mountainous areas often have a lot of natural wealth. The existence of geological appearances in the form of outcrops which are products of intrusion and alteration, indicates that the Pacitan area is a mineralized zone. In this study, geophysical measurements were carried out using the Induced Polarization (IP) method in the area where mineralization was suspected. The polarization induction method is expected to prove the presence of a mineralized zone in the Pacitan area. From the research results, line 1, line 4, line 5, line 6 and line 7 are areas with high chargeability values. So it can be proven that the area with high resistivity and high chargeability is an area with mineralization. Judging from the geological conditions on the surface, there are also outcrops which show that there is an intrusion and the result of alteration. So it can be concluded that the area has a fairly high mineralization. In measuring the correlation between magnetic anomalies and IP, the results are very supportive of each other that the area is a mineralized area, if we look at the resistivity, and chargebility.

Abstract

The astromi indonesia traversed a line equator Provides the potential for maximum solar energy, this energy source be used to recycle water. Indonesia as a country maritime had area of water 62,89% from area of Indonesia, but this fact does not guarantee the large number of clean water supplies in each region. The instrument recycle water with solar energy designed to produce clean water be used solar radiation absorbed by flat plate collector will Help the process of evaporation dirty water A container at the top of a collector, So that will yield water vapor and the condensed form the grain of the water (condensate) On the surface of cover collector, so Of the water where they cleansed and pruned already can be funneled into a clean water storage. The rate of volume clean water every hour is 217,5 ml with temperature 37,2oC and The intensity of sunlight on cover collector is 350 Cd. This clean water can not be consumed by body and Need to processed further by a chemical process.

Abstract

The phenomenon in the industrial revolution 4.0 era shows that more business actors are utilizing digital media as a marketing tool, including HerJamu products in Bengkalis District which optimizes Digital Marketing strategies to strengthen its position in the market. This study aims to determine the effect of Digital Marketing and Customer Relationship Marketing on consumer loyalty of HerJamu products with a sample of 85 respondents taken through accidental sampling techniques. Data analysis was carried out using classical assumption tests, multiple linear regression, and model feasibility tests consisting of coefficients of determination, multiple correlations, F tests, and t tests. The results of the study indicate that Digital Marketing has a positive and significant effect on consumer loyalty, which means that the more optimal the implementation of digital marketing strategies, the higher the consumer loyalty of HerJamu products. In addition, Customer Relationship Marketing has also been proven to have a positive and significant effect on consumer loyalty, so that the better the implementation of customer relationship strategies, the stronger the consumer bond in using HerJamu products in Bengkalis District.
