Abstract

Bali merupakan daerah yang sangat disukai oleh berbagai spesies lebah madu termasuk jenis Trigona (Lebah Kele). Permintaan madu lebah Trigona dipasaran nasional cukup tinggi. Potensi pasar yang sangat besar bagi penjualan madu Trigona sesungguhnya membuat budidaya ini memiliki potensi ekonomi yang sangat besar dan dapat dijadikan alternatif peningkatan kesejahteraan masyarakat. Walaupun lebah jenis trigona ini keberadaannya cukup melimpah di Desa Aan, namun karena kurangnya pengetahuan budidaya lebah Kele dari peternak, mengakibatkan kurang optimalnya pengembangbiakan koloni. Selain itu limbah pasca panen dari peternakan lebah juga belum mendapat perhatian yang optimal. Dari hasil survey yang dilakukan terdapat beberapa masalah pada mitra diantaranya sulitnya menangkar lebah Kele liar, bagaimana pemanenan yang benar sehingga tidak merusak koloni, pemasaran madu dan memanfaatkan ampas perasan (propolis) Kele. Di tahun 2018 melalui program Udayana Mengabdi telah dilaksanakan pelatihan pembuatan sabun berbahan limbah propolis kele yang diberikan kepada ibu-ibu peternak. Dari kegiatan tersebut tercetus ide untuk mengembangkan kewirausahaan sosial dengan memanfaatkan sumber daya alam sekitar. Solusi yang ditawarkan pada program ini diantaranya, memberikan pelatihan budidaya Kele, membantu terbentuknya industri rumah tangga ibu-ibu peternak dan pengadaan website pemasaran. Hasil akhir dari kegiatan ini adalah peningkatan pengetahuan dan keterampilan mitra dan pembentukan entitas bisnis (kewirausahaan sosial) yang melibatkan anggota mitra.

Abstract

Agricultural insurance is an insurance in agriculture sector that is relatively newly introduced in Indonesia. Agricultural insurance based on rainfall index is one of the risk management tool to keep farmers in case of crop failure. This study aims to determine the steps in determining the value of rainfall index on agricultural insurance and calculate the value of agricultural insurance premiums based on simulated rainfall index by Stochastic weather generator with mixed exponential distribution. The results of this study provide value if the amount of rainfall 103,71 mm so that the amount of premium payments equal to Rp19.016, and if the rainfall is high 128.35 mm then the amount of premium payment equal to Rp1.088.000.

Abstract

The aim of this research was to measure the risk of the IHSG stock data using the Value at Risk (VaR). IHSG stock index data typically indicates a jump. However, Geometric Brownian Motion (GBM) model can not catch any of the jumps. To view the jumps, it is necessary that the model was then developed into a Geometric Brownian Motion (GBM) model with Jumps. On the GBM model with Jumps, returns the data are discontinuous. To determine the value of VaR, the value of return to perform the simulation model of GBM with Jumps is required. To represent processes that contain jumps, discontinuous Poisson process using the Peak-Over Threshold is required. To determine the parameters of model, calibration of historical data using the Maximum Likelihood Estimation (MLE) method is performed. VaR value for GBM model with Jumps with a 95% and 99% confidence level are -0,0580 and -0,0818 while VaR value for GBM model with a 95% and 99% confidence level are -0,0101 and -0,0199. VaR for GBM model with Jumps with a confidence level of 95% and 99% show greater than the model VaR for GBM.

Abstract

Udayana University is one of the universities that have developed an e-learning system that is coupled with the IMISSU (Integrated Management Information System of the Udayana) system and is known as the ELSE-U (E-Learning Smart and Elegant of Udayana). This system was built with the aim of accommodating online lectures. But in reality there are still many lecturers, especially in the Mathematics Department who have not utilized the learning media. Many reasons related to the media have not been utilized. In this study, a material development strategy and learning using ELSE-U will be initiated for conceptual mathematics material in order to obtain optimal benefits. In addition, the measurement of the level of acceptance and use of the utilization of ELSE-U in learning is carried out using the Technology Acceptance Model (TAM) method. The results showed that the internal and external factors of students did not affect the perceived ease of use in the use of ELSE-U, organizational factors (study programs, faculties, and universities) had a significant effect on perceived usefulness and perceived ease of use in the use of ELSE-U, while student behavior in addressing the use of ELSE-U has a significant effect on students' intention to use it.

Abstract

The guarantee minimum on unit-linked insurance applies only to the most extreme situations of very bad rate of return on the fund’s policyholders. One of the investment guarantees commonly used in unit-link is guaranteed minimum death benefit (GMDB). The final value under unit-linked insurance contracts can be expressed in terms of options that can be calculated using the Black-Scholes-Merton method. The purpose of this study is to determine the effect of age to the guarantee minimum value calculated using the Black-Scholes-Merton method. The calculation of GMDB value based on case simulation in this study resulted that the increasing age of the insured the greater the minimum guarantee value to be obtained.

Abstract

This study aimed to apply glowworm swarm optimization (GSO) algorithm as an alternate way to obtain optimal bandwidth in geographically weighted regression (GWR) model with adaptive kernel function. The result showed that GSO was able to obtain optimal bandwidth with lower cross validation (CV) value than the traditional way that was using k-nearest neighbor (KNN) algorithm. Unfortunately, the running time of GSO was far slower than KNN was.
