Abstract

Citra merek sebuah produk bertujuan untuk menarik perhatian konsumen. Untuk mendukungnya, maka perlu adanya iklan. Dalam iklan terdapat bahasa yang menarik sehingga calon konsumen memahami produk. Namun kenyataannya terdapat pelajar kelas XI SMAN 2 Trenggalek tidak memperhatikan informasi iklan produk yang akan dibeli. Penelitian ini memiliki tujuan untuk mengetahui pengaruh bahasa iklan, citra merek, terhadap keputusan pembelian. Penelitian dilakukan pada pelajar kelas XI SMAN2 Trenggalek, teknik pengambilan sample memakai metode probability sampling dengan random sampling. Teknik pengumpulan data memakai uji validitas dan uji reliabilitas. Teknik analisis data memakai regresi linear sederhana, regresi linear berganda, uji T dan uji F. Hasil penelitian hipotesis 1 ditemukan pengaruh bahasa iklan terhadap keputusan pembelian, hipotesis 2 terdapat pengaruh citra merek terhadap keputusan pembelian. Sedangkan hasil uji F menunjukkan ftabel sebesar 3,12 dimana fhitung (36,551) > ftabel (3,12) dan tingkat signifikannya 0,000 < 0,05 yang artinya terdapat pengaruh yang signifikan. Dengan demikian dapat disimpuklan bahwa ada pengaruh secara parsial dan simultan antara variabel bahasa iklan, citra merek, terhadap keputusan pembelian.

Abstract

The Energy and Mineral Resources Office of Central Java Province has proposed the evaluation of the CAT Semarang-Demak groundwater conservation zone for the 2022 fiscal year. There it was announced that the evaluation in the Semarang-Demak Groundwater Watershed (CAT) in Semarang City, there is already a critical utilization zone (mera). Groundwater withdrawal, which tends to be more intensive over time, will have an impact on the quantity, quality, and carrying capacity of the local environment, and can lead to groundwater level subsidence and land subsidence. As an effort to fight and anticipate further environmental damage, groundwater management in Semarang City needs to be evaluated. This evaluation uses a geographic information system (GIS)-based approach method in making a spatial model of the damaged groundwater utilization zone in the Semarang City Groundwater Basin. This evaluation was carried out to determine the distribution and characteristics of the aquifer, hydrogeological conditions, groundwater and environmental conditions, groundwater protected areas, water needs for the community and its development. The results of the Evaluation, Mapping, and Analysis Study of Damaged Zones for Groundwater Utilization in Groundwater Catchment Areas in Semarang City can be used as a reference for the Central Java Provincial Government in making groundwater management policies according to its authority.

Abstract

This study compares two types of glass materials applied to a box-type solar cooker, namely low-iron glass and soda-lime glass. Low-iron glass is produced with a reduced iron oxide content, resulting in a higher transparency level compared to soda-lime glass, which affects its optical properties, particularly transmittance. The testing was conducted under two conditions: a stagnation test and a load test using 1 kg of water. The results indicated that the soda-lime glass system was superior, successfully boiling water up to 101.25 °C with a thermal efficiency of 0.48, an F1 value of 0.22, and an F2 value of 0.51. In contrast, the low-iron glass failed to boil the water, as the temperature only reached 79.25 °C, and it did not meet the load test feasibility standard, recording an F2 of 0.13 and an efficiency of 0.25.
