Judul: Designing Business Recylist: Waste Management Platform Through the Customer Discovery
Abstrak: Indonesia memiliki gap antara jumlah timbulan sampah dengan pengelolaannya di industri daur ulang. Recylist merupakan waste management platform yang dapat memenuhi ketersediaan bahan baku sampah pelaku usaha daur ulang. Rumusan masalah dan tujuan penelitian ini didasarkan atas penggunaan metode customer discovery agar menciptakan Recylist bersifat product-market fit. Jumlah sampel ditentukan 15 orang pada proses uji masalah dan lima orang pada proses uji solusi. Data diolah menggunakan analisis model Miles and Huberman dan statistik deskriptif. Pada tahap awal, Recylist menargetkan calon pengguna dari sisi industri daur ulang kepada earlyvangelist yang ditetapkan dengan jumlah 19.431 usaha di ProvinsiJakarta dan Jawa Barat. Hasil akhir penelitian ini berupa rancangan model bisnis dan high-fidelity prototype berbasis teknologi yang telah terverifikasi berdasarkan hasil proses pada tahap hipotesis, uji masalah, dan uji solusi sehingga diputuskan bahwa model bisnis dapat dilanjutkan pada tahapan customer development selanjutnya., Indonesia has a gap between the amount of waste generated and its management in therecycling industry. Recylist is a waste management platform that can fulfil the availability of waste raw materials for recycling businesses. The problem formulation and objectives of this researchare based on the use of the customer discovey method to create Recylist product-market fit.The number of samples was determined to be 15 people in the problemtest process and fivepeople in the solution test process. Data was processed using Miles and Huberman model analysis and descriptive statistics. In the first stage, Recylist targeted potential users from the recycling industry sector to the defined earlyvangelists with a total of 19,431 businessesin Jakarta and West Java Provinces.

Judul: Pengaruh Ph Terhadap IgG Anti H5N1 Asal Kolostrum Sapi Yang Divaksin Dengan Vaksin Avian Influenza H5N1
Abstrak: The aims of this study is to determine the stability of IgG anti-H5 from bovine colostrum (BC) after exposure to acid and basic pH. Two samples of BC, whole colostrum and whey colostrum incubated at pH 4, 5, 9, and 10 for 30 and 60 minutes. Haemagglutination Inhibition (HI) test is used to determine IgG titer after incubation. IgG titers decreased after exposure to acid or basic pH. Acid exposure (pH 5) decreased antibodi titer of whole colostrum as much as 3,75% and 16,25% after incubation 30 and 60 minutes respectively. Antibody titer to pH 4 also decreased until 12,5% and 16,5% after for 30 and 60 minutes respectively. In whey colostrum, both pH 4 and pH 5 reduce 18,75% antibody titer. On other hand, IgG titers is decreased until 100% at basic pH (pH 9-10). In conclusion, IgG from BC is degraded in acidic and alkaline conditions.
