Customer Service is any activity that is intended or intended to provide customer satisfaction, through services that can fulfill the desires and needs of customers. Sign facilities are signs or information that are placed or installed at airport terminals, made clear, easy to understand and function to explain or provide instructions, warnings, regulations, prohibitions and orders for all users or service users at the airport. The purpose of this study is to find out how much influence the performance of Customer Service and Sign placement has on the level of passenger satisfaction at Zainuddin Abdul Majid International Airport. This study uses quantitative data. The data used in this study were taken from primary data based on questionnaires distributed to passengers at Zainuddin Abdul Majid International Airport from August to October 2022. With a total of 150 people, the data analysis technique used was Multiple Linear Regression Analysis, T Test , F Test and Coefficient of Determination. The results showed that H1 was rejected and H2 was accepted, which means that the calculation results of the F test showed the calculated F value = 0.829181 ftable value = 0.737812. It is very clear that H1 and H2 are accepted. The T test shows a significant value of the X1 variable to the Y variable, namely = 0.003244 Less than the threshold value Significance = 0.05 means that Customer Service Performance has a significant effect on Passenger satisfaction and a significant value of the Variable X2 to Variable Y, namely = 0.040887 Smaller than the threshold value. Significance = 0.05 means that the Placement of Sign Facilities has a significant effect on Passenger satisfaction. The results of the Coefficient of Determination test which shows how much the X1 variable is Customer Service performance and the X2 variable is the placement of Sign Facilities on the Y variable passenger satisfaction is known to be a determination coefficient of 78.7%, which means that the X1 variable is Customer Service performance and the X2 variable is the placement of Sign Facilities. Y variable is passenger satisfaction. contributed 78.7% to the Y variable of passenger satisfaction with a Correlation Value = 0.92087 (Very Strong).

The objectives of this study are: 1) To find out how much influence the level of advertising attractiveness has on the purchasing decisions of UNIQLO consumers on Instagram. 2) To find out how much influence the quality of advertising messages has on purchasing decisions of UNIQLO consumers on Instagram. 3) To find out how significant the influence of celebrity endorser use is on UNIQLO consumer purchasing decisions on Instagram. This research uses a quantitative approach, and the analysis used is multiple linear regression. The research sample used was 100 people who actively use Instagram. There are three variables in this study, namely: the attractiveness of the ad, the quality of the advertising message, and the celebrity endorser. The results of this study indicate that the variables of advertising attractiveness and celebrity endorsers have a positive effect on purchasing decisions. Meanwhile, the variable quality of advertising messages has no effect on purchasing decisions of UNIQLO consumers on Instagram.Tujuan penelitian ini yaitu: 1) Untuk mengetahui seberapa besar pengaruh tingkat daya tarik iklan terhadap keputusan pembelian konsumen UNIQLO di Instagram. 2) Untuk mengetahui seberapa besar pengaruh kualitas pesan iklan terhadap keputusan pembelian konsumen UNIQLO di Instagram. 3) Untuk mengetahui seberapa signifikan pengaruh penggunaan selebriti endorser terhadap keputusan pembelian konsumen UNIQLO di Instagram. Penelitian ini menggunakan pendekatan kuantitatif, dan analisis yang digunakan adalah regresi linear berganda. Sampel penelitian yang digunakan sebanyak 100 orang yang aktif menggunakan Instagram. Variabel dalam penelitian ini sebanyak tiga variabel, yaitu: daya tarik iklan, kualitas pesan iklan, dan selebriti endorser. Hasil penelitian ini menunjukkan bahwa variabel daya tarik iklan dan selebriti endorser berpengaruh positif terhadap keputusan pembelian. Sedangkan, variabel kualitas pesan iklan tidak berpengaruh terhadap keputusan pembelian konsumen UNIQLO di Instagram.

Pasir besi atau titanomagnetit ditemukan di wilayah pesisir pantai Indonesia yang tersebar dari Aceh hingga pantai utara Papua. Kandungan logam berharga seperti besi, titanium, dan vanadium belum dimanfaatkan dengan baik karena hingga saat ini belum ada pabrik pengolahan dan pemurnian (smelter) di dalam negeri yang mampu mengolah pasir besi hingga menjadi produk akhir dengan nilai tambah yang tinggi. Perusahaan di dalam negeri hanya mampu mengolah pasir besi hingga menjadi konsentrat. Ulasan literatur ini disusun dengan harapan dapat menjadi salah satu langkah awal perkembangan teknologi pengolahan dan pemurnian pasir besi di Indonesia. Hasil ulasan literatur menunjukkan bahwa pasir besi atau titanomagnetit telah diproses baik menggunakan teknologi rotary kiln – electric furnace maupun tanur tiup (blast furnace). Penelitian terus berkembang ke arah teknologi reduksi langsung karena kemungkinannya untuk menghasilkan terak titanium dengan kadar tinggi. Artikel ini juga membandingkan parameter yang berpengaruh dalam proses reduksi langsung konsentrat pasir besi atau titanomagnetit yang terdiri dari pengaruh reaktor, reduktor, temperatur proses, dan penambahan bahan imbuh. Rekomendasi juga diberikan sebagai saran untuk perkembangan penelitian selanjutnya dalam reduksi konsentrat pasir besi atau titanomagnetit.
