Abstract

Cultivation of tiger prawns stands as a crucial sector in Indonesia's fisheries industry, significantly contributing to the country's foreign exchange. However, challenges persist in the cultivation process, particularly concerning suboptimal harvest outcomes. A critical factor in tiger prawn cultivation is the water temperature within shrimp ponds, a parameter directly influencing shrimp growth. The recommended normal temperature range is 28-31°C. Deviations from this range can adversely impact the shrimp's metabolic system and appetite, resulting in stress and potential mortality. Temperature fluctuations can lead to severe issues such as hindered growth, reduced productivity, and increased shrimp mortality. Real-time monitoring of air temperature emerges as a pivotal element in ensuring the success of shrimp farming. This research aims to provide a practical solution for shrimp cultivation by presenting a system that enables farmers to adjust air temperature in ponds in real-time through a user-friendly website application. The ability to promptly respond to abnormal temperature fluctuations empowers farmers to optimize cultivation conditions, thereby reducing shrimp mortality rates. The research focuses on creating a water temperature monitoring system for tiger prawn ponds using cloud storage through the Firebase platform. By implementing real-time temperature monitoring, financial risks for shrimp farmers can be mitigated, preventing losses attributed to temperature-induced shrimp mortality. The research utilizes the DS18B20 temperature sensor and WeMos D1 R2 as the control center. The website displays air temperature measurements, showcasing a high accuracy of 99% with a minimal error of 1.2%. This underscores the system's effectiveness in measuring air temperature both above and below the pond. The incorporation of IoT technology for monitoring water quality in ponds offers a practical and innovative approach to tiger prawn cultivation, with the potential to enhance production outcomes in each harvest.

Abstract

One of the problems in providing infrastructure is the lack of interest in managing infrastructure. AWS Lambda is a FaaS (Function as a Service) service that allows users to run code automatically in an environment managed by Amazon Web Services. In this study, the method used is to collect data on code execution time at various input sizes, then perform an analysis of the factors that affect execution time. Furthermore, optimization is carried out by selecting the appropriate memory size and proper coding techniques to improve performance. The results show that optimizing memory size and coding can improve code execution time performance by up to 30%, depending on the type of service used. This can help AWS Lambda users improve code performance and save on operational costs.

Abstract

Indonesia, a tropical country with a growing population, has significant potential for food production but faces challenges in meeting this demand. Factors such as generation change, industrialization, and food production monopolies, as well as climate change, food security measures, and a lack of technological progress, affect productivity. Governments need to address these problems by implementing policies such as cost efficiency, supply chain management, minimum labour consumption, and effective food distribution. Food security is vital to the health and well-being of the population, and food is a vital food source to consume. Vegetables, a popular food source, are vital for health and growth. Salad, a plant used for food production, is beneficial to food production and is the main food in the modern market. Technologically speaking, food security is vital to the health and well-being of the population. Governments should focus on improving food security and ensuring that food is accessible to all. The proposed system consists of five sensors: the DHT11 sensor, the TDS meter, the humidity sensor (DS18B20), the water height sensor, and the pH meter. Data from the sensor will be stored in a cloud database via the LoRa communication network, allowing users to access data through Android applications.

Abstract

This research implements an oxygen monitoring system in tiger shrimp ponds using a Dissolved Oxygen (DO) sensor based on Wemos D1 R1 with an Internet of Things (IoT) approach. Tiger shrimp ponds, as aquaculture centers, require regular monitoring of water quality. The system uses DO sensors in the water, processed by Wemos D1 R1, and the data is sent to Firebase Cloud for storage. A web application serves as the user interface to monitor and analyze the data. The results of the research in Pandawa 1000 tiger shrimp pond, Lanrisang Village, Pinrang, showed the positive impact of IoT technology on pond management. The selection of the Wemos D1 R1 and the use of the Dissolved Oxygen Sensor enabled accurate and efficient measurement of oxygen levels, overcoming the shortcomings of previous research, especially the integration of the sensor directly into Firebase for real-time data storage and delivery. This development improves connectivity and real-time monitoring capabilities, crucial aspects in ensuring optimal pond water quality.

Saat ini, UPT PJP UMI telah memiliki website, namun pengelolaannya belum memenuhi standar penilaian webometrics, sehingga belum optimal dalam mempengaruhi peringkat webometrics UMI. Beberapa permasalahan muncul, seperti performa website yang mendapatkan nilai "B" berdasarkan pengukuran GTMetrix, jumlah backlink yang masih kurang, dan konten berita yang belum menggunakan standar SEO. Kegiatan pengabdian terfokus pada sosialisasi peningkatan pemeringkatan webometrics dan pendampingan dalam workshop manajemen konten website berbasis SEO. Hasil dari kegiatan ini mencakup peningkatan pemahaman pemeringkatan webometrics, peningkatan kemampuan pengelolaan website mitra, serta penyerahan modul "Pedoman Pengelolaan Website Berdasarkan Penilaian Webometrics" kepada UPT.PJP UMI. Hasil kegiatan ini berhasil mencapai tujuannya dengan memberikan kontribusi positif dalam meningkatkan kualitas pengelolaan website UPT.PJP UMI berdasarkan standar penilaian webometrics. Perolehan hasil persentase kuisioner pre dan posttest menunjukkan bahwa dari 10 orang peserta sosialisasi dan workshop mengalami peningkatan pemahaman tentang pemeringkatan webometrics dari 54% menjadi 76%. Diharapkan dengan peningkatan pemahaman peserta pelatihan dapat memberikan arah perubahan pemeringkatan webometrics UMI menjadi lebih baik di Tahun 2024 nantinya.

Abstract

Smk Latanro Enrekang merupakan salah satu sekolah kejuruan yang berada di kota Enrekang. Saat ini ada beberapa guru dan siswa yang memanfaatkan jaringan internet dari sekolah. Namun manajemen bandwidth di sekolah ini belum dapat digunakan secara optimal dalam mencukupi kebutuhan pengguna, dimana ketika banyaknya pengguna akses internet pada saat jam belajar dan kepentingan administrasi akan menyebabkan penggunaan banwdwith menjadi lambat. Salah satu cara untuk mengurangi penurunan performansi adalah dengan mengatur pembagian bandwidth antar pengguna dengan tepat. Penelitian ini bertujuan untuk mengukur performansi jaringan di SMK Latanro Enrekang dengan metode Per Connection Queue (PCQ) dan Hierarchical Token Bucket (HTB) serta menganalisa parameter pengukuran performansi jaringan dengan menggunakan Quality of Service (QoS). Hasil penelitian menunjukkan nilai rata-rata throughput dengan metode PCQ 1,2 Mbps dengan kategori TIPHON “Bagus” serta nilai rata-rata throughput dengan metode HTB  1,0 Mbps dengan kategori TIPHON “Bagus”, nilai rata-rata packet loss dengan metode PCQ 0,3% dengan kategori TIPHON “Sangat Bagus” serta nilai rata-rata packet loss dengan metode HTB 0,3% dengan kategori TIPHON “Sangat Bagus” dan nilai rata-rata delay dengan metode PCQ 6.42 ms dengan kategori TIPHON “Sangat Bagus” serta nilai rata-rata delay dengan metode HTB 5.92 ms dengan kategoriTIPHON “Sangat Bagus”.
