Judul: Rancangan Model Sistem Penunjang Keputusan Dalam Perancangan Usaha Mikro dan Kecil Olahan Komoditas Lele Dumbo (Clarias gariepinus)
Abstrak: Business feasibility studies is one of the requirements to lodge financing to investors. Leleku.com sistem aims to help building the appropriate financial feasibility model so that the owner may submit financing toward investors, either individual investors or financial institutions. The sistem was made by using reference data from similar Small & Micro Enterprises (SME) gain through direct interviews, afterwards, a web-based application is made by using programming language, namely HTML, PHP, Javascipt, CSS, JQuery and using MySQL as the database. The modeling sistem is formed into two subsistem, covering database management subsistem ( DBMS ) and basic model management sub-sistem ( MBMS ). After being verified with researched data, the feasibility value for both SME was formed, with details as such : (1) For Karmina SME resulting NPV of Rp 469,884,900; 129% ROI; 2.99 of IP; 2.69 for B/C ratio; and Pay-back period after 10 months with profit of Rp 112,475,300/year. (2) For Al-Fardh SME resulting NPV of Rp 283,385,500; 149% ROI; 2.91 of IP; 2.66 for B/C ratio; and Pay-back period after 8 months with profit of Rp 68,323,700/year. From both name of SME, it appears that both SME deserved to be established and for investors, this is very promising because these businesses will gain big profit each year, which are Rp 112,475,300/year or Rp 9,372,900/month (Karmina SME) and Rp 68,323,700/year or Rp 5,693,600/month (Al-Fadh SME).

Judul: Pengembangan Model Bisnis dan Studi Kelayakan Finansial Produk Dried Breadcrumbs di PT LeGitt Boga Mandiri
Abstrak: Desain model bisnis produk dried breadcrumbs dari PT LeGitt Boga Mandiri berhasil dikembangkan dari B2B menjadi B2C menggunakan metode BMC. BMC Existing mewakili model bisnis B2B yang saat ini diterapkan oleh mitra dan BMC Improved mewakili pengembangan model bisnis ke pasar B2C dengan segmentasi menengah ke bawah. Hasil model bisnis ke pasar B2C dipelajari kelayakannya menggunakan metode studi kelayakan dengan sumber data dan asumsi yang telah divalidasi bersama mitra. Studi kelayakan memberikan hasil parameter kelayakan NPV Rp 50.876.013.370,-, PBP 46 Bulan, IRR 48,82%, ROI 73,78%, dan B/C 1,208 serta tetap mempertahankan harga yang dapat bersaing dengan produk serupa di segmentasi menengah-ke-bawah. Hasil analisis sensitivitas pada kenaikan harga bahan baku 3% dan 15% menunjukkan hasil yang tetap layak, sehingga bisnis yang dirancang memiliki ketahanan yang tinggi meskipun nantinya ada perubahan variabel maupun asumsi yang mempengaruhi biaya., The business model design for the dried breadcrumbs product by PT LeGitt Boga Mandiri has successfully improved from B2B to B2C using the BMC method. The existing BMC represents the current B2B business model applied by partners, while the improved BMC represents the development of the business model for the B2C market targeting the lower-middle segment. The feasibility of the business model for the B2C market was studied using a feasibility study method with data sources and assumptions validated by partners. The feasibility study results show the following viability parameters, NPV of Rp 50.876.013,370,-, PBP of 46 months, IRR of 48.82%, ROI of 73.78%, and B/C ratio of 1,208, while maintaining competitive pricing with similar products in the middle-to-low segment. Sensitivity analysis results for a 3% and 15% increase in raw material prices still indicated viability, demonstrating that the designed business has high resilience even with potential changes in variables or assumptions affecting costs.

Judul: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
