Remote temperature monitoring is needed in hazardous area conditions or fast data retrieval is needed without being limited by distance. This condition can be overcome by monitoring and measuring the temperature from a remote location using internet technology that is currently developing, namely the Internet of things. There are many implementations of remote temperature monitoring systems, but the measurement results of these sensors sometimes have very significant differences even for measuring the temperature of the same object. This study aims to analyze the implementation of an effective and efficient remote temperature monitoring system. The temperature measurement process uses the LM35 and MLX 90614 sensors based on Internet of things technology using the Message Queue Telemetry Transport (MQTT) protocol. After obtaining the results of temperature measurements using different sensors, the measurement results are analyzed and compared with standard temperature measuring instruments to obtain an effective and efficient implementation. Based on the analysis, the results of temperature measurements using the MLX 90614 sensor are effective and efficient sensors.

So far, the distribution of zakat has been done by Muzaki (obliged to pay zakat, or giving zakat) giving directly to people who get zakat. The impact of this arises from queues of people who get zakat, the distribution of zakat is not evenly distributed, sometimes some get double and some don't. Therefore, it is necessary to socialize better zakat management, namely through the Amil Zakat Institution and Baznas so that the distribution of zakat can be maximally evenly distributed. The method of implementing this socialization is by giving lectures in vitual or online because it is still in a state of covid 19. From this service, community members have a better understanding and understanding of the distribution or distribution of zakat through the Amil Zakat Institute and Baznas.

Along with the development of information technology that is increasingly rapid, the use of information technology at this time is an important requirement in every agency or company An educational institution requires good administrative management with the aim to improve services to students, the school payment system in the form of Education Provision Contribution (SPP) and Donation of Institutional Development (SPI) at SMP Muhammadiyah 3 Semarang is still done conventionally, where the recording of data and the payment process of SPP and SPI are written into diaries, ledgers and spreadsheet applications which results in the accumulation of data in the form of archives. In the data collection of students and the payment process takes a relatively long time, so that during the payment process results in long queues in the administration and requires a long time to make payment reports and arrears SPP and SPI which are needed quickly.Developments in the field of science and technology were developed with the aim of solving problems and making it easier for users to complete work tasks. The use of barcode technology is one of the technologies that can respond to the provision of fast, accurate and accurate information. Barcode technology is applied to student cards that function as student IDs and also as student payment cards

Pengaduan sering menjadi salah satu permasalahan di perusahaan yang sangat berpengaruh terhadap kinerja karyawan dan perusahaan. Kurangya perhatian terhadap masalah yang terjadi diperusahaan, baik itu masalah kecil atau besar sangat memprihatinkan. Pada masa sekarang dengan semakin canggihnya teknologi permasalahan seperti pengaduan keluhan dapat diselesaikan dan diproses secara cepat. Untuk membantu konsumen yang mengalami masalah dan mengutarakan keluhannya melalui pengaduan. Maka dari itu dibuatlah Queue System Pengaduan Pelanggan Internet Service Provider (ISP) Menggunakan Metode First In First Out (FIFO) yang bertujuan untuk memudahkan pelanggan untuk melakukan pengaduan dan menyampaikannya kepada perusahaan. Sistem ini dibuat dengan menggunakan bahasa pemrograman PHP. Hasil dari penelitian ini adalah Sistem antrian pengaduan (Queue System) yang dapat memproses pengaduan pelanggan.
