Abstract

ABSTRAKPeningkatan terhadap kebutuhan akses data membuat Visible Light Communication (VLC) menjadi alternatif media transmisi nirkabel yang efisien. Namun berdasarkan performansinya, VLC memiliki permasalahan data rate yang tidak merata diterima oleh User Equipment (UE). Dalam mengatasi permasalahan tersebut, penelitian ini menerapkan alokasi daya kirim dengan algoritma waterfilling yang mampu memberikan keadilan data rate setiap UE berdasarkan nilai kanal. Penelitian ini menggunakan kanal Line Of Sight (LOS) dengan 3 skenario berbeda. Kami menggunakan parameter validasi untuk mengukur setiap kinerja dengan nilai Signal Noise Ratio (SNR), data rate, fairness index dan efisiensi energi. Dari hasil simulasi menggunakan algoritma waterfilling, kami memperoleh nilai fairness index untuk data rate sebesar 100% namun tidak memiliki efisiensi daya. Dengan memodifikasi algorima waterfilling, terjadi penurunan fairness index, SNR serta data rate, tapi memberikan efisiensi energi LED hingga 9%. Dengan demikan, daya yang dipancarkan oleh LED memiliki lifetime yang lebih panjang dengan modified waterfilling.Kata kunci: VLC, Power Allocation, Waterfilling, Fairness. ABSTRACTThe increase in the need for data access makes Visible Light Communication (VLC) an alternative wireless transmission medium that is efficient. However, based on its performance, VLC has a data rate problem that is not evenly accepted by User Equipment (UE). In overcoming this problem, this study applies power allocation with waterfilling algorithm that is able to provide fair data rate for each UE based on channel value. This study uses the Line Of Sight (LOS) channel with 3 different scenarios. We use validation parameters to measure each performance using the Signal Noise Ratio (SNR) value, data rate, fairness index and energy efficiency. From the results of simulation using the waterfilling algorithm, we obtain a fairness index value for the data rate of 100% but does not have a power efficiency. By modifying the waterfilling algorithm, there is a decrease in the fairness index, SNR and data rate, but provide LED energy efficiency of up to 9%. Thus, the power emitted by the LED has a longer lifetime with modified waterfilling algorithm.Keywords: VLC, Power Allocation, Waterfilling, Fairness.

Abstract

The study aimed to test the effectiveness of ambon banana stems flour through feeding on the health status and performance of the groupers reared in the sea floating net cages. The groupers (8.27 ± 0.20 cm length and 11.69 ± 0.50 g weight) were reared in 1 m × 1 m × 1.5 m floating net cages with a stocking density of 112 fish /m3 for 42 days. The feed was commercial feed with 46% and 48% protein, which was added with 30 g/kg of ambon banana stems flour with a coating method. This study consists of three treatments and three replications, i.e. feeding at the beginning of reared for 7 days (A), 14 days (B), and feeding without ambon banana stems flour (control). The observed parameters were production performance, morphometric, hematological test, and water quality. The results showed that the production performance between treatments was not significantly different (P>0.05). Based on the morphometric test the total length for treatment A increased significantly (P <0.05) compared to the control and B. On the 14th day of the hematological test, it was known that the highest total erythrocyte, hemoglobin, hematocrit, and total leukocyte was found in treatment B, however, the differential leukocyte did not differ significantly (P>0.05). The addition of Ambon banana stems flour in feed in the first 14 days (B) can improve health status but has not been able to increase production performance and morphometric grouper. Keywords: cantang grouper fish, production performance, health status, Ambon banana stems flour ABSTRAK Tujuan penelitian ini adalah menguji efektivitas tepung batang pisang ambon dalam pakan terhadap status kesehatan dan kinerja produksi ikan kerapu cantang yang didederkan dalam KJA di laut.
