Abstract

One of the application of zeolite as a multi-function mineral is the use as catalyst. Investigation to utilize Indonesian natural zeolite as a catalyst will increase the added value and gives a chance to reduce the dependency of imported catalyst. One of the main property, which allow zeolite to be used as a catalyst, is a high silica-alumina ratio, where Si/Al >10. As a preminalry stage to form a catalyst zeolite, research has been carried out to increase the Si/Al ratio of natural mordenite from Cikalong, Tasikmalaya. The method applied is dealumination process, which is followed by calcinations and ion exchange. This process is expected to modify the Na-zeolite from natural mordenit to be a NH4-zeolite which can be transformed to a catalyst zeolite. Dealumination process is carried out using HNO3, with variable concentration and time at temperature of 85°C. Thereafter, zeolite is calcined at 700°C and is followed ion exchange process using NH4NO3. The current stage of research has been succeeded to increase the Si/Al ratio of natural mordenite from Si/Al @ 5 to Si/Al > 10. The process condition applied is dealumination with 8N HNO3 for 24 hours at 85°°C and is followed by calcinations at 700°C for 2 hours. Ion exchange is proceeded with 5% NH4NO3 for 2 hours and is followed by another calcinations at 400°C for 2 hours.

Abstract

 Perkembangan dunia usaha saat ini berjalan dengan pesat, secara tidak langsung menciptakan suatu persaingan di bidang pemasaran. Semakin banyak konsumen yang merasa puas dengan barang atau jasa yang ditawarkan, maka volume penjualan di perusahaan tersebut pun akan meningkat. Faktor – faktor yang mempengaruhi volume penjualan ialah : (1) harga, (2) promosi, (3) produk yang ditawarkan, (4) saluran distribusi, (5) mutu. Harga menjadi salah satu pertimbangan utama ketika konsumen akan membeli suatu produk yang mereka inginkan. Adapun tujuan penelitian ini untuk mengetahui : (1) gambaran penetapan harga jual yang dilakukan oleh Tungku Café and Resto, (2) gambaran volume penjualan pada Tungku Café and Resto, (3) pengaruh penetapan harga jual terhadap volume penjualan di Tungku Café and Resto. Metode penelitian yang digunakan ialah metode deskriptif dengan menggunakan teknik pengumpulan data secara langsung melalui observasi dan wawancara. Hasil penelitian menunjukkan bahwa (1) penetapan harga jual menggunakan metode cost plus pricing mengalami fluktuatif dengan rata –rata margin sebesar 23%, (2) volume penjualan mengalami fluktuatif dengan rata – rata penjualan sekitar 38 produk yang terjual, (3) besarnya pengaruh penetapan harga jual terhadap volume penjualan sebesar 57,76% (koefisien determinasi). Hasil uji hipotesis diketahui bahwa   lebih besar dari  (3,697 ≥ 2,228) artinya Ho ditolak dan Hi diterima. Hal ini menunjukkan bahwa penetapan harga berpengaruh signifikan terhadap volume penjualan Kata kunci : Penetapan harga, cost plus pricing, volume penjualan.
