Judul: Consumer Attitudes and Preferences Toward Gayo Arabica Coffee in East Aceh Regency and Langsa City
Abstrak: Penelitian bertujuan mengidentifikasi keputusan pembelian, juga menganalisis sikap dan preferensi konsumen terhadap kopi arabika gayo. Penelitian ini menggunakan data primer yang diperoleh melalui survei google form. Responden yang berpartisipasi sebanyak 223 orang. Data dianalisis menggunakan analisis deskriptif, analisis multiatribut fishbein, dan analisis conjoint. Hasil penelitian yang diperoleh menunjukkan bahwa proses pengambilan keputusan konsumen melalui lima tahapan keputusan dan hasil perbandingan antara tiga varian kopi arabika yaitu kopi arabika gayo, kopi sidikalang, dan kopi mandheling (lintong). Sikap konsumen terhadap kopi arabika gayo lebih positif sebesar 170,16 poin. Kopi arabika gayo memiliki keunggulan pada atribut rasa, aroma, ketersediaan produk, after taste, dan informasi produk. Hal ini didukung dengan hasil preferensi konsumen pada tingkat kepentingan atribut, atribut rasa memiliki tingkat kepentingan atribut tertinggi pada produk kopi arabika gayo sebesar 30,79 persen. Konsumen juga lebih menyukai kopi arabika gayo yang memiliki rasa manis, aftertaste lengket, aroma yang menyengat, kekentalan yang ringan dan harga Rp 35.000/250g. Produsen harus melakukan perbaikan pada produk yang belum sesuai harapan konsumen, juga meningkatkan dan mempertahankan produk yang sudah memenuhi harapan konsumen., The research aims to identify purchasing decisions, as well as to analyze consumer attitudes and preferences towards gayo arabica coffee. This research uses primary data from an online survey using google forms involving 223 respondents who participated. Data were analyzed using descriptive analysis, fishbein multi-attribute analysis, and conjoint analysis. The research results show that the consumer decision making process goes through five decision stages. The comparison between three variants of arabica coffee, namely gayo arabica coffee, sidikalang coffee, and Mandheling (lintong) coffee show that consumer attitudes towards gayo arabica coffee are more positive by 170.16 points. Gayo arabica coffee has advantages in the attributes of taste, aroma, product availability, aftertaste, and product information. This is supported by the results of consumer preferences on the level of attribute importance; the taste attribute has the highest level of attribute importance in gayo arabica coffee products at 30.79 percent. Consumers also prefer gayo arabica coffee, which has a sweet taste, a lingering aftertaste, strong aroma, light viscosity and a price of Rp 35,000/250g. Therefore, producers need to make improvements to product attributes that do not meet consumer expectations, as well as improve and maintain product attributes that meet consumer expectations.

Judul: Analisis Daya Saing Kopi Arabika Gayo di Kabupaten Aceh Tengah
Abstrak: Kopi merupakan salah satu tanaman perkebunan yang menjadi komoditas ekspor unggulan Indonesia. Kabupaten Aceh Tengah merupakah salah satu penghasil kopi terbaik yaitu Arabika Gayo yang sudah mendapatkan Indikasi Geografis dan juga Fair Trade Certified dari Organisasi International Fair Trade pada tanggal 27 Mei 2010. Permasalahan usahatani kopi Arabika Gayo di Kabupaten Aceh Tengah adalah produktivitas yang masih rendah, pencatatan keuangan petani yang buruk sehingga tidak mengetahui usahanya layak atau tidak serta tidak memiliki data terhadap faktor yang paling mempengaruhi pendapatan maupun pengeluaran. Penelitian ini menganalisis tentang daya saing kopi Arabika Gayo dan pengaruh penurunan harga serta biaya tenaga kerja terhadap daya saing usahatani kopi Arabika Gayo di Kabupaten Aceh Tengah. Penelitian ini menggunakan metode Policy Analysis Matrix (PAM) dan analisis sensitivitas. Hasil analisis PAM menunjukkan bahwa usahatani kopi gayo di Kabupaten Aceh Tengah memiliki keunggulan komparatif dan kompetitif. Hasil analisis sensitivitas menunjukkan bahwa penurunan harga sebesar 52 persen dan kenaikan upah tenaga kerja sebesar 330 persen mengakibatkan kopi Arabika Gayo tidak layak secara ekonomi.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
