Judul: Backend Development of High Performance REST API Based IoT Data Server Applications Using Golang Gin and Postgresql
Abstrak: Internet of Things (IoT) menjadi salah satu bidang teknologi yang semakin banyak digunakan. Platform yang digunakan untuk manajemen perangkat dan data IoT salah satunya adalah ThingSpeak. Sayangnya, platform ini memiliki banyak keterbatasan untuk pengguna yang tidak berbayar. Saat ini telah dikembangkan server data IoT berbasis REST API menggunakan Python Falcon dan Postgresql sebagai alternatif untuk menghilangkan keterbatasan tersebut. Dalam penelitian ini, akan dikembangkan ulang API tersebut dengan bahasa pemrograman Go dan framework Gin agar API dapat memiliki kinerja yang tinggi. Metode yang digunakan dalam pengembangan API ini adalah iterative waterfall. Dari hasil pengujian, API Golang Gin ini berhasil meningkatkan kinerja lebih dari 600 kali lipat daripada Python Falcon. Pada endpoint GET /node/id kinerja meningkat menjadi 1256 TPS, sedangkan pada POST /channel kinerja meningkat menjadi 2076 TPS. Jika cache digunakan secara maksimal, GET /node/id bisa mencapai 8097 TPS., The Internet of Things (IoT) is becoming one of the increasingly used areas of technology. One of the platforms used for data and IoT devices management is ThingSpeak. Unfortunately, this platform has many limitations for non-paid users. Currently, a REST API-based IoT data server has been developed using Python Falcon and Postgresql as an alternative to eliminate these limitations. In this research, the API will be re-developed with Go programming language and Gin framework so that the API can have high performance. The method used in the development of this API is iterative waterfall. From the test results, the Golang Gin API managed to improve performance more than 600 times compared to Python Falcon. At the GET /node/id endpoint the performance increased to 1256 TPS, while at POST /channel the performance increased to 2076 TPS. If the cache is maximally used, performance of GET endpoint can increase to 8097 TPS.

Judul: Developing and Improving REST API IoT Server Performance by Using Golang Fiber
Abstrak: Perkembangan dan kebutuhan internet of things (IoT) semakin tinggi di masyarakat. Data yang diambil oleh perangkat IoT tidak bisa disimpan dalam perangkat itu sendiri karena kapasitas memorinya yang terbatas. Oleh karena itu, dibutuhkan server yang bisa menyimpan dan menganalisis data yang didapatkan. Dalam penelitian ini, peneliti mengembangkan aplikasi server IoT kinerja tinggi berbasis REST API dengan menggunakan framework Golang Fiber, kemudian membandingkan kinerjanya dengan aplikasi sejenis yang menggunakan framework Python Falcon dan Python Sanic. Metode yang digunakan untuk pengembangan aplikasi adalah metode waterfall. Pengukuran kinerja dilakukan pada VPS dengan spesifikasi 4 vCPU dan RAM 8 GB menggunakan perangkat lunak ‘siege’. Dari hasil perbandingan kinerja, didapatkan bahwa aplikasi Golang Fiber dapat melayani klien hingga 2250 transaction per second (TPS), nilai tersebut 73 kali dan 2 kali lebih baik dibandingkan dengan Python Falcon dan Python Sanic. Aplikasi Golang Fiber juga memiliki penggunaan memori yang efisien, yaitu sebesar 628,8 MB, nilai tersebut 1,7 kali dan 5 kali lebih efektif dibandingkan dengan Python Falcon dan Python Sanic., The development and demand of internet of things (IoT) continues to grow in society. Data gathered by an IoT device cannot be saved in the device itself because of its low memory capacity. Therefore, there is a need for a server that can analyze and store the obtained data. In This research, researcher developed a high performance IoT server based on REST API with Golang Fiber framework, then compare its performance and memory usage to similar application which use Python Falcon and Python Sanic. The method used for developing the application is waterfall. Load testing were carried out on a VPS with 4 vCPU specifications and 8 GB RAM using the 'siege' software. Based on the comparison result, Golang Fiber application can serve the client until 2250 transaction per second (TPS), this value is 73 times and 2 times faster than Python Falcon and Python Sanic. Golang Fiber application also have efficient memory usage of 628,8 MB, this value is 1,7 times and 5 times more effective than Python Falcon and Python Sanic.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
