Abstract

Upredictable natural conditions cause fish larvae to die because they cannot adapt to these conditions, leading to potential harvest failure. Changes in natural conditions due to weather result in unstable pH levels in pond water. Fish Farmers traditionally attempt to improve water pH quality using by manual pH meters, but This method has limitations if not monitored periodically. Based on this problems, researchers plan to develop a water acidity measurement tool using an IoT-based E4502C pH sensor to help fish farmers monitor pond pH levels through their smartphones. Testing the pH sensor showed an average error rate of 4.09% at pH 4, 2.47% at pH 7, and 6.31% at pH 9. More accurate results can be achieved by collecting more data and processing it to determine the average values before displaying them on the user interface.

Abstract

Today, the current development of Batam City is not only in the development of industrial and tourism areas but also leads to the development of agriculture and plantations. This was done as a form of effort in maintaining food security for areas in Batam City, where initially a lot of food needs were supplied from areas on the island of Sumatra. The city of Batam, whose territory consists of islands, creates obstacles in the development of agricultural land and plantations. Among them are types of soil that are difficult for seasonal crops to grow; water resources that depend on rainwater; as well as access to agricultural and plantation locations that are spread across several islands, making it difficult to deliver logistics and agricultural products. Soil conditions greatly affect the quality of the plants produced, and the type of soil will affect the types of plants suitable for planting. Based on these obstacles, the Batam State Polytechnic formed a Community Service team to support the agricultural land development program, one of which was the development team for portable soil condition measuring devices in collaboration with a partner from "Kelompok Tani Maju Mandiri" on Setokok Island. Community service activities are carried out in stages, apart from field surveys in order to identify the needs of farmer groups, the current community service period has reached the development of portable soil condition measuring devices with test results still in laboratory testing and not yet testing on actual agricultural land. The field survey results describe the condition of the partner's agricultural soil, which is brownish-red in color, mostly clay. Plants that are quite successful in the form of green curly chili plants. The water source comes from small rain-fed reservoirs prepared around agricultural land. The results of the measuring instrument design have reached the laboratory testing stage, which has shown the value of soil nutrition. Testing measurements on agricultural land directly and assisting partners in operating measuring instruments will be carried out at the next community service stage.

Abstract

Elevator are one of the most important transportation these days. Elevator is a link in a tall building that has many floors. The role of the elevator which is always used by the public requires a high level of precision. In this study, researchers made a prototype elevator system using a stepper motor and obtained test results with a maximum error rate of 2% on the 10 cm elevator input using a ruler as a testing tool. The largest comparison of testing result using a ruler and using a rotary encoder is 0.2 cm or 2 mm at the 40 cm elevator input. The precision of the elevator prototype still can be improved by using half step mode when controlling the stepper motor.

Abstract

A pressure vessel is a container designed to hold fluids under pressure, including liquids and gases with varying pressures and temperatures. The pressure exerted on the vessel's walls and body is a critical factor that must be carefully considered to ensure compliance with applicable international design standards and prioritize worker safety and security. This research focused on a pressure vessel to investigate the impact of temperature on shell thickness to meet ASME standards. The study utilized shell components made from SA-516 Gr 70 and SA-537 materials. Experiments were conducted with each material at temperatures of 250°C, 235°C, and 343°C, revealing that thickness varies based on material and temperature. The research findings demonstrate compliance with ASME standards, as the shell thickness in all trials exceeded the minimum specified in the drawings.
