Abstract

Nanotechnology is believed to give a significant added value to the agricultural industry. Various applications of nanotechnology provide opportunities for improving the global competitiveness of the agricultural industry. This study aims to assess nanotechnology development strategy at the national agricultural industry by using the quantitative SWOT method and ANP in BOCR (benefit, opportunity, cost, risk) perspective. The results from these two approaches were then compared. There were four stages of the research procedure that consists of 1) analyzing agricultural industries that apply nanotechnology using quantitative SWOT, 2) formulating nanotechnology development strategy in the TOWS matrix quantitatively, 3) determining strategy alternative for developing nanotechnology in the agricultural industry with ANP in BOCR perspective and 4) assessing comparatively weight value of each strategy alternative using quantitative SWOT and ANP in BOCR perspective. Data were collected by conducting FGD (group discussion forum) for 20 participants and a questionnaire to 10 experts in the field of food chemistry, agriculture, nanotechnology and policy. Results show that in the formulation of nanotechnology development strategy on national agriculture industry, aspects of opportunities and positive impact are taken to account more than that risk and economic aspects. ANP results indicate that nanotechnology development in the national agricultural industry is still in the early stage where the strategy that leads to increased mastery of technology is paid more intention than the implementation of research result itself, socialization of nanotechnology safety and governance of policies. Strategy formulation done by ANP in BOCR perspective is slightly different than that done by quantitative SWOT method which uses only independent variables. The result of this study can be used as a reference for stakeholders for strategic decision making in relation to improving the competitiveness of the national agricultural industry through the development of nanotechnology.

Abstract

Kalsium pirofospat telah berhasil disintesis dari limbah kerang menggunakan metoda solvothermal dan pemanasan. Limbah kerang yang digunakan adalah kerang hijau dan kerang darah sebagai bahan baku kalsium karbonat. Kalsium oksida didapatkan dengan cara mengkalsinasi kalsium karbonat pada temperatur 1000°C selama 2 jam dengan kondisi atmosfir biasa. Selanjutnya, CaO dicampur dengan H3PO4 pada proses solvothermal guna mendapatkan fasa CaHPO4. Kalsium pirofospat diperoleh dengan cara memanaskan serbuk CaHPO4 pada temperatur 800°C selama 2 jam dan kondisi atmosfir biasa. Hasil analisa fasa menunjukkan terbentuknya fasa tunggal kalsium pirofospat tanpa adanya fasa pengotor lainnya untuk limbah kerang darah. Hal yang berbeda untuk limbah kerang hijau, dimana pengotor ditemukan selain fasa kalsium pirofospat. Ukuran partikel rata-rata untuk kalsium pirofospat dari limbah kerang hijau adalah 1.5 ± 0.8 µm, sedangkan kalsium pirofospat dari limbah kerang darah adalah 258 ± 294 nm.

Abstract

Nanobubble (NB) technology produces highly stable nano-sized bubbles with wide applications in water treatment, agriculture, and aquaculture. This study analyses the influence of gas pressure on NB formation, bubble size distribution, and dissolved oxygen (DO) levels in water, aiming to understand how pressure affects NB characteristics and oxygen dissolution efficiency. NBs were generated using a cartridge nozzle with pressurised oxygen gas at pressure values of 0.1, 0.2, and 0.3 kPa for 30 minutes. The results show that gas pressure is a key parameter for nanobubble size and distribution. At a pressure of 0.1 kPa, the average size was 170 nm, decreasing to 110 nm at 0.2 kPa and 93 nm at 0.3 kPa with a more homogeneous size distribution. As the NB size decreased, the DO concentration increased. The initial DO value of 2.42 mg/L increased rapidly over the first 5 minutes to 32.40 mg/L and then to 35.34 mg/L after 30 minutes for 0,3 kPa pressure. This trend is similar to NBs produced at another pressure. This study confirms that gas pressure variation is an important parameter in controlling NB formation and increasing DO, thereby supporting the development of efficient aeration technology for various applications.
