Judul: Business Feasibility Analysis of Fish Culture Based on Fintech Crowdfunding: Asian Seabass (Lates calcarifer)
Abstrak: Kakap putih menjadi salah satu komoditas ekspor unggulan yang mampu mendongkrak pertumbuhan ekonomi dan peningkatan sumber devisa. Peningkatan produksi budidaya menjadi salah satu usaha untuk memenuhi kebutuhan ikan nasional. Namun, banyak hambatan dalam proses budidaya yang menyebabkan menurunnya produktivitas, diantaranya keterbatasan dana usaha. Growpal memiliki platform Crowdfunding yang memudahkan pembudidaya mengajukan bantuan pendanaan untuk usaha budidaya nya. Penelitian ini bertujuan menganalisis kelayakan bisnis pembesaran kakap putih (Lates calcarifer) dengan sistem pendanaan Fintech Crowdfunding. Metode analisis data yang digunakan dalam penelitian ini terdiri dari analisis aspek non finansial dan aspek finansial yang dianalisis secara kuantitatif dengan menggunakan kriteria kelayakan investasi, serta analisis sensitivitas (switching value). Analisis kelayakan bisnis pembesaran kakap putih berbasis Fintech Crowdfunding didapatkan NPV sebesar Rp194.228.465, Net B/C sebesar 7, IRR sebesar 97%, dan Payback period selama 1,26 tahun. Hasil analisis menunjukkan bahwa bisnis layak untuk dijalankan dan prospektif untuk didanai, serta lebih sensitif terhadap penurunan tingkat kelangsungan hidup., Seabass is one of the leading export commodities capable of boosting economic growth and increasing sources of foreign exchange. Increasing aquaculture production is of the effort to meet the needs of fish nationally. However, there are many obstacles in the cultivation cause a decrease in productivity, including limited business capital. Growpal has a Crowdfunding platform that makes it easy for farmers to apply for funding assistance for their cultivation. This study aims to analyze the business feasibility of raising seabass (Lates calcarifer) using the Fintech crowdfunding system. The data analysis method used in this study consists of the analysis of non-financial aspects and financial aspects are analyzed quantitatively using investment eligibility criteria, as well as a sensitivity analysis. Analysis of the business feasibility of raising seabass based on Fintech Crowdfunding obtained a Net Present Value of Rp194.228.465, a Net Benefit-Cost Ratio of 7, and an Internal Rate of Return of 97%, and a Payback Period of 1.26 years. The result show that the business is feasible and prospectively to be funded and is also more sensitive to decreasing the survival rate

Judul: The Role of Fintech in The Development of Vaname Shrimp Cultivation
Abstrak: Komoditas ekspor andalan Indonesia pada sektor perikanan salah satunya adalah udang vaname (Litopenaeus vannamei). Kegiatan akuakultur membutuhkan modal dalam menunjang kegiatan budidaya untuk memenuhi biaya operasional dan proses distribusi budidaya dari hulu hingga hilir. Hambatan yang dihadapi dalam kegiatan budidaya diantaranya yakni akses permodalan yang terbatas dalam pengembangan usaha akuakultur. Fintech merupakan layanan keuangan secara online yang menggabungkan keuangan dan teknologi dengan peranan yang cukup penting karena dapat meningkatkan akses finansial pembudidaya. Fintech yang bergerak dalam mendukung kegiatan akuakultur salah satunya adalah Infishta. Tujuan dari penelitian ini yakni menganalisis peran pendanaan fintech dalam pengembangan dan keberlanjutan usaha budidaya udang vaname. Penelitian ini dimaksudkan untuk menggali fakta terkait manfaat pendanaan fintech terhadap usaha akuakultur dengan menggunakan metode studi kasus yang terdiri dari data primer dan sekunder. Hasil penelitian menunjukkan bahwa pendanaan senilai 30% yang diberikan fintech dari total biaya dapat memberikan tambahan modal untuk pengembangan usaha dengan penambahan luas lahan produksi dari 26,8 ha menjadi 41,4 ha. Produksi yang dihasilkan meningkat menjadi 45,11 ton dari 32,24 ton akibat adanya penambahan luas lahan produksi. Berdasarkan aspek finansial, usaha budidaya udang vaname yang dilakukan layak untuk dijalankan karena memiliki nilai NPV > 0, net B/C ≥ 1, dan IRR > discount factor serta sensitif terhadap penurunan tingkat kelangsungan hidup dan kenaikan harga pakan. Namun, pada klaster C sesudah pengembangan usaha tidak memenuhi kriteria aspek finansial sehingga tidak layak dijalankan., One of Indonesia's primary export commodities in the fishery is vaname shrimp (Litopenaeus vannamei). Aquaculture activities require capital to support cultivation activities to meet operational costs and the distribution process of cultivation from upstream to downstream. Obstacles faced in cultivation activities include limited access to capital in the development of aquaculture businesses. Fintech is an online financial service that combines finance and technology with a reasonably significant role because it can increase the financial access of cultivators. Fintech engaged in supporting aquaculture activities, one of which is Infishta. This study aims to analyze the role of fintech funding in the development and sustainability of vaname shrimp farming businesses. This study is intended to explore facts related to the benefits of fintech funding to aquaculture businesses using a case study method consisting of primary and secondary data. The results showed that funding worth 30% of fintech's total cost could provide additional capital for business development by increasing the production land area from 26.8 ha to 41.4 ha. The production increased to 45.11 tons from 32.24 tons due to the increase in land area. Based on the financial aspect, the vaname shrimp farming business that is carried out is feasible to run because it has an NPV value of > 0, net B/C ≥ 1, and IRR > discount factor and is sensitive to decreases in survival rates and increases in feed prices. However, in cluster C, after business development, it does not meet the criteria for financial aspects, so it is not feasible to run.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
