Judul: Analisis Preferensi Konsumen terhadap Merchandise K-Pop di Toko Online Dulsetstore
Abstrak: Dulsetstore merupakan toko online yang menyediakan merchandise K-Pop yang berasal dari agensi HYBE Labels. Selama dua tahun terakhir, pendapatan toko online ini mengalami stagnan. Selama ini Dulsetsore hanya melakukan promosi dan open PO (pre-order) ketika ada idol group yang come back. Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik konsumen, menganalisis preferensi konsumen, menganalisis proses keputusan pembelian dan menyusun implikasi manajerial. Pengambilan sampel dilakukan dengan teknik purposive sampling dengan jumlah 100 sampel. Data dalam penelitian ini diolah dengan analisis deskriptif dan analisis konjoin. Atribut merchandise K-Pop yang paling penting adalah keaslian produk. Preferensi kombinasi atribut yang paling disukai adalah produk merchandise K-Pop yang official dengan harga < Rp 1.000.000, ketersediaan produk ready stock, pembayaran secara cicilan, dan packaging premium.

Judul: Pengaruh Social Media Marketing, e-WOM dan Kualitas Produk terhadap Keputusan Pembelian Produk Fanmade K-Pop
Abstrak: Berkembangnya aliran musik ini yang diiringi dengan naiknya populasi penggemar K-Pop, sehingga menyebabkan terbentuknya berbagai komunitas penggemar di Indonesia. Para penggemar akan menginginkan barang-barang yang berkaitan dengan idolanya. Hal ini merupakan suatu peluang bagi para penggemar untuk memulai ide bisnis fanmade yang berkaitan dengan K-Pop. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen, menganalisis pengaruh social media marketing, e-WOM, dan kualitas produk terhadap keputusan pembelian serta menganalisis faktor yang paling berpengaruh terhadap keputusan pembelian produk fanmade K-Pop. Metode analisis data yang digunakan adalah analisis deskriptif dan analisis SEM-PLS. Penarikan sampel dilakukan dengan menggunakan metode non-probability sampling dengan teknik purposive sampling. Hasil penelitian menunjukan bahwa social media marketing, e-WOM dan kualitas produk memiliki pengaruh yang positif dan signifikan terhadap keputusan pembelian dengan variabel social media marketing memiliki pengaruh yang lebih kuat., The growth of K-Pop music is also accompanied by the growing number of K-Pop fans, resulting in the emergence of various K-Pop communities in Indonesia. The fans will want to have items that are associated with their idols. It allows fans the opportunity to start a fan-made business related to K-Pop. The purpose of this research is to identify consumer characteristics and to analyze the effect of social media marketing, e-WOM, product quality, and the most influential factor contributing to the purchase decisions of K-Pop fanmade products. In drawing the samples, the researcher used the non-probability sampling method with the purposive sampling technique. The data analysis method used descriptive analysis and SEM-PLS analysis. The result showed that social media marketing, e-WOM, and product quality had a positive and significant effect on purchasing decisions, with the social media marketing variable being the strongest.

Judul: Pengembangan kandidat vaksin iradiasi Brucella abortus isolat lapang
Abstrak: Brucellosis is a strategic contagious animal disease in Indonesia, which is caused by Bru/:ella abortus (B. abortus). Brucellosis causes abortion, still birth, orchitis; arthritis, infertility and sterility lowering milk production. Eradication of cattle in many countries have been conducted by test and slaughter and vaccination programme. At the moment there are two vaccinations available to control bovine brucellosis; those are B. abortus S 19 and B. abortus RB51. One of the problems in the eradication is not enough a vaccine. The objective of this research was to develop irradiated brucellosis vaccine from B. abortlls local isolate through isolation, identification and biotyping B. abortus from field cases. Determination of B. abortus radiation dose and in vivo study was done in guinea pigs. The samples were collected from milk (Bandung, west Jawa), amnion fluids (diagnostic sample) and higroma fluids (Be1u, NIT). In this study we use three isolates that were SBDG-13C (milk), CAM-08/306 (amnion fluids), and CH09- BL (higroma fluids). Biotyping of the three isolates categorized as B. abortus biotype I. Standard curves of B. abortus was made by calculating bacteria cells number indirectly. Linear equation of the standard curve of SBDG- J3C; CAM- 08/306 and CH09-BL isolates were y = 7.2119x + 6.7723; y = 3.889lx + 7.5278 and y = 2.9829x + 7.9612 respectively (x is absorbance value and y is log number of cells/ml). Observation on the growth of the isolates after Gamma irradiation showed variation responses to the value LDso of isolate CAM-08/306, CH09-BL and SBDG-I3C were 13.5; 11.9, and 17.9 Gy, respectively. The in vivo study showed that the spleen of irradiation vaccinated guinea pigs was a swelling (splenomegaly) and contained 102 to 106 CFU bacteria. Based on the results, It seems likely that those three isolates have not been defined as candidate isolate for brucellosis vaccine.
