Judul: The Impact of the Covid-19 Pandemic on the Gayo Coffee Supply Chain
Abstrak: Kebijakan Pembatasan Sosial Berskala Besar (PSBB) yang diterapkan pemerintah selama pandemi Covid-19 berpengaruh ke banyak sektor, salah satunya rantai pasok kopi. Tingkat ketergantungan dan kompleksitas rantai pasok menyebabkan rantai pasok menjadi lebih rentan terhadap pengaruh pandemi Covid-19, penundaan dalam mendistribusi kopi sehingga membutuhkan penambahan modal yang harus disiapkan oleh pelaku kopi Gayo. Petani kopi juga ikut merasakan penurunan pendapatan akibat dari harga beli kopi yang rendah. Hal ini menyebabkan hasil kopi yang dihasilkan tidak langsung didistribusikan melainkan dilakukan penundaan masa panen,masa penyimpanan dan juga pengolahan. Penelitian ini berfokus pada struktur rantai pasok kopi Gayo sebelum pandemi dan masa pandemi. Metode yang digunakan ialah pendekatan deskriptif kuantitatif dengan menggunakan data primer yang diperoleh dari wawancara dan data sekunder. Analisis deskriptif frekuensi dilakukan pada distribusi karakteristik 122 responden. Hasil penelitian ini menunjukkan struktur rantai pasok Kopi Gayo terdiri dari petani, kolektor dan koperasi, sedangkan pola rantai pasok lainnya terdiri dari petani, pedagang pengumpul, kolektor, pedagang kopi lokal, UMKM dan koperasi selaku ekportir. Terdapat adanya pengaruh perubahan produksi, harga dan pendapatan sebelum pandemi dan masa pandemi. Implementasi manejerial yang dapat diterapkan dengan sistem kemitraan atau kelembagaan dan sertifikasi., The Large-Scale Social Restrictions (PSBB) policy implemented by the government during the Covid-19 pandemic has affected many sectors, one of it was the coffee supply chain. The level of dependence and complexity of the supply chain causes the supply chain to become more vulnerable to the influence of the Covid-19 pandemic, delays in distributing coffee, requiring additional capital to be prepared by Gayo coffee suppliers. Coffee farmers also experienced a decrease in income due to low coffee purchasing prices. This means that the coffee produced is not distributed immediately but rather delays the harvest, storage and processing periods. This research focuses on the Gayo coffee supply chain before the pandemic and during the pandemic, including aspects of structure, production, price and income. The analytical method used is quantitative descriptive analysis using primary data sourced from interviews with 122 samples consisting of 100 farmers, 20 traders/collectors, and 2 cooperatives. Descriptive analysis to explain the characteristics of respondents. Quantitative analysis to show the effect of the pandemic on production, prices and profits using the difference test. The research results show that the supply chain structure of Gayo Coffee consists of farmers, collectors and cooperatives, while other supply chain patterns consist of farmers, collecting traders, collectors, local coffee traders, MSMEs and cooperatives as exporters. Different test results show that the Covid-19 pandemic has significantly reduced production, prices and profits at the farmer, collector and cooperative levels.

Judul: The Effectiveness Marketing Communication of MSME Coffee in the Covid-19 Pandemic Era
Abstrak: Tingkat konsumsi kopi dalam negeri cukup tinggi dan meningkat secara signifikan, sehingga sektor hilir semakin bertumbuh dan berkembang seperti UMKM (Usaha Mikro, Kecil, dan Menengah) yang bergerak dalam komoditas kopi. Pandemi Covid-19 telah menimbulkan berbagai masalah bahkan kerugian bagi UMKM, sehingga komunikasi pemasaran terpadu yang efektif sangat diperlukan supaya UMKM dapat bertahan dan berkembang. Penelitian yang dilakukan di Kopi Sisi Kiri, Kota Bogor, Provinsi Jawa Barat ini bertujuan untuk menganalisis efektivitas komunikasi pemasaran terpadu yang dilakukan oleh UMKM. Analisis dilakukan menggunakan uji korelasi Rank Spearman dengan melibatkan responden sebanyak 30 orang yang berkunjung ke Kopi Sisi Kiri. Hasil penelitian menunjukkan bahwa Kopi Sisi Kiri sudah intensif dalam melakukan komunikasi pemasaran terpadu, terutama melalui iklan sebagai yang paling intensif diikuti oleh hubungan masyarakat dan penjualan personal, lalu promosi penjualan dan pemasaran langsung. Komunikasi pemasaran yang dilakukan Kopi Sisi Kiri cukup efektif karena terbukti berkorelasi positif dengan perilaku konsumsi, terutama dalam aspek kognitif dan afektif. Penjualan personal adalah komunikasi pemasaran yang paling efektif karena berkorelasi positif dengan ketiga aspek perilaku konsumsi, sementara iklan dan hubungan masyarakat hanya berkorelasi dengan aspek kognitif serta promosi penjualan yang hanya berkorelasi dengan aspek kognitif dan afektif. Perilaku konsumsi juga terbukti berkorelasi dengan karakteristik konsumen, terutama tingkat pendidikan dan tingkat pendapatan., The level of coffee consumption is quite hight and has increased significantly, so that the downstream sector is grow and developing such as MSME’s engaged in coffee commodities. The Covid-19 Pandemic has caused various problems and even losses for MSME’s, so that effective integrated marketing communication is very much needed for MSME’s can be survive and develop. This research will be held in Kopi Sisi Kiri, Bogor City, West Java Province aims to to analyze the effectiveness integrated marketing communication carried out by MSME’s. The analysis was carried out using the Rank Spearman correlation with involve 30 respondents who visited Kopi Sisi Kiri. The results showed that Kopi Sisi Kiri was already intensive in carrying out integrated marketing communications, especially through advertising as the most intensive followed by public relation and personal selling, then sales promotion and direct marketing. The marketing communication conducted by Kopi Sisi Kiri is quite effective because it is proven to be positively correlated with consumption behaviour, especially in cognitive and affective aspects. Personal selling is the most effective marketing communication because it is positively corelated with all three aspects of consumption behaviour, while advertising and public relation only correlate with cognitive aspects and sales promotion which only correlate with cognitive and affective aspects. Consumption behaviour is also showed correlated with consumer characteristics, mainly due to education level and income level.

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.
