Abstrak: Keuangan syariah merupakan suatu konsep keuangan yang menggunakan nilai-nilai Islam dalam pelaksanaannya. Keuangan syariah ini sangat menjunjung nilai keadilan, melarang riba (bunga), dan gharar (kurangnya informasi). Oleh karena itu, keuangan syariah memiliki konsep bagi hasil atau yang dikenal juga sebagai Profit Loss Sharing (PLS) yaitu perjanjian kerjasama antara dua pihak atau lebih untuk melakukan suatu usaha dengan kesepakatan keuntungan ataupun kerugian akan ditanggung bersama. Dengan konsep bagi hasil, tidak akan ada pihak yang tereksploitasi atau dirugikan. Dalam karya ilmiah ini, dilakukan penambahan dana tabarru’ ke dalam model PLS. Dana tabarru’ merupakan kumpulan dana yang berasal dari pedagang di mana jika terjadi kerugian, maka pedagang akan mendapatkan dana itu kembali sebagai santunan. Penarikan kesimpulan dilakukan dengan membandingkan hasil penghitungan profit dari model bagi hasil atau PLS dan model PLS dengan penambahan dana tabarru’. Hasil yang didapat menyatakan bahwa model PLS lebih menguntungkan bagi pedagang dan investor dibandingkan dengan model PLS dengan tambahan dana tabarru’., Islamic finance is a financial concept that uses Islamic values in its implementation. The Islamic finance strongly upholds the value of justice, prohibits riba (interest), and gharar (lack of information). Therefore, Islamic finance has the concept of profit sharing or also known as Profit Loss Sharing (PLS) which is a cooperation agreement between two or more parties to conduct a business with an agreement that profits or losses will be shared. With this profit sharing concept, no party will be exploited or harmed. In this scientific work, the addition of tabarru' funds into the PLS model is carried out. Tabarru' funds are a collection of funds originating from traders where if there is a loss, the trader will get the funds back as compensation. Conclusions are drawn by comparing the results of calculating profits from the profit sharing model or PLS and the PLS model with the addition of tabarru' funds. The results obtained indicate that the PLS model is more profitable for traders and investors compared to the PLS model with additional tabarru' funds.

Judul: Sharia-based Micro Investment Modeling Using Profit Loss Sharing Model
Abstrak: Investasi merupakan aktivitas ekonomi yang sering dilakukan untuk mendapatkan keuntungan. Salah satu cara yang dapat dilakukan adalah dengan memberikan pinjaman kepada individu atau kelompok yang membutuhkan dana. Peminjam membutuhkan modal untuk membangun usahanya, sedangkan pemberi pinjaman menginvestasikan uangnya kepada peminjam dengan bunga sebagai keuntungannya. Akan tetapi, praktik bunga ini sering kali merugikan salah satu pihak, yaitu pedagang dengan laba harian yang kecil. Oleh karena itu, investasi syariah menghadirkan praktik investasi pinjaman yang lebih adil bagi kedua belah pihak. Dengan konsep bagi hasil yang ditawarkan, pedagang dengan laba harian kecil bisa mendapatkan keuntungan tanpa khawatir dirugikan. Dalam penelitian ini, model bunga atau rentenir dan model bagi hasil atau Profit Loss Sharing (PLS) diterapkan dalam suatu transaksi pinjaman antara pedagang dan investor, dengan nilai bunga dan porsi bagi hasil yang beragam dan besar pinjaman beragam pula. Selanjutnya dari masing-masing model, dilakukan penghitungan return yang didapatkan oleh investor dan pedagang lalu dibandingkan hasilnya. Hasil yang didapat menyatakan bahwa model PLS lebih aman bagi pedagang dibandingkan dengan model rentenir., Investment is a common economic transaction for gaining profit. Issuing loans to individuals or groups who need funds is one of the ways to invest. Lender, as the investor, will acquire profit from their investment in the form of interest on the loan from the borrower. However, this interest model is a burden for the borrower, especially traders with very low daily profit. Thus, a fair way of investing for both investor and borrower such as sharia investment is considered. This investment model is based on the concept of Profit Loss Sharing (PLS), which enables traders to access the capital they need without having to endure the excessive risks of loan. In this study, investment modelling is established for the interest model (loan shark model) and the PLS model with various interest and profit sharing portions and various credit sizes. The calculation of return of both models for the investor and borrower are performed and then compared. The result shows that the PLS model is safer for the traders than the loan shark model.

This species amount in the nature is very small, caused by the illegal hunting and trading. The purpose of this research is to get the information about population and habitat of the cockatoo in Flores, especially at the western part of Mbeliling Landscape. Cocatoo census was conducted by look-down method at vantage points when cockatoo flew passed by. Habitat analysis was carried out with vegetation analysis. The census showed that there were two groups of cockatoo, consisted of 69 cockatoos in Tao hill and 15 cockatoos in Nggoer River. Flight pattern of each group ranged 0-100 meters above the sea level and crossed mangrove forest, savanna, monsoon forest and cultivation plant vegetation. The vegetation analysis resulted Ceiba petandra or silk-cotton tree as the tree that most used by cockatoo and had the highest TIV (Tree Importance Value), 47,48%. Cockatoo’s foods which observed were crown flower (Calotropis gigantea), and Moringa olifera.
