Biopestisida dengan efektifitas dan efisiensi tinggi akan mendukung keberhasilan praktek proteksi tanaman di lapangan.  Tahapan yang cukup penting dalam produksi biopestisida berkualitas adalah formulasi.  Penelitian ini bertujuan untuk mempelajari formulasi biopestisida berbahan dasarTrichoderma asperellum yang diisolasi dari tanah di PTPN XII Kediri, Jawa Timur.  Proses formulasi dilakukandengan seleksi substrat padat untuk produksi konidia, uji konsistensi substrat, uji scaling up produksi substrat dan uji daya simpan biopestisida.  Seleksi substrat dilakukan terhadap lima kombinasi substrat padat yaitu beras 100%; beras:jagung (50%:50%); beras:jagung (75%:25%); beras:jagung (25%:75%) dan jagung 100%.  Hasil menunjukkan bahwa beras 100% merupakan substrat terbaik untuk produksi konidia T. asperellum (3 x 109 konidiag-1).  Uji konsistensi beras 100% sebagai substrat dilakukan dalam dua tahap yaitu dalam volume sama dengan uji seleksi dan dalam volume lebih besar sebagai uji scaling up.  Hasil menunjukan terdapat konsistensi antara kedua uji tersebut dengan uji seleksi (7,88 x 109 dan 7,95 x 109 konidiag-1).  Uji daya simpan T. asprellum pada beras 100% menunjukkan stabilitas jumlah konidia (≥ 105 konidia g-1) sampai 105 hari setelah simpan pada suhu ruang.  Oleh karena itu, formulasi T. asprellum sebagai biopestisida dapat menggunakan beras 100% sebagai substrat.

Over that last few decades there has been a significant rise in interest for design-led entrepreneurship and innovation. This has brought about the need to expand on the principles and methods of human-centred design by incorporating knowledge from multiple disciplines, such as management, business, and entrepreneurship studies. This expansion aids designers, engineers, and marketing practitioners who strive to create innovative, meaningful and relevant services, business models and experiences. More often than not, ventures operate under very limited resources, and practitioners are often required to fulfil several roles. The concept of ‘multidisciplinary teams’ widely spread in this sphere often bears little resonance in these contexts. Designers possess valuable competencies that can have a significant impact on the venture, especially driving user and context-centred strategy and processes for the introduction, legitimization and scaling-up stages. However, engaging with these areas of practice requires skills and capacities that overlap traditional disciplinary roles. In doing so, the boundaries between design and engineering, branding and communications, cultural and behavioural insight, marketing and management strategy are blurred. As educators in design innovation, how do we explore, define and balance interdisciplinary relationships between design, engineering, management, business and entrepreneurship theories, methods, language and models of education? The purpose of the entrepreneurship in design education track is to discuss methods, models, case studies, research, insights and unexpected knowledge in benefits and limitations of design entrepreneurship education. In particular, the three papers presented in this track demonstrate different approaches to entrepreneurship and design education.
