Perkembangan teknologi pada saat ini telah maju dan pesat. Hal ini dapat dimanfaatkan dalam bidang pertanian, khususnya pada lahan pertanian para petani di Dukuh Tambakroto Desa Tambaksari yang telah memiliki wadah organisasi bernama GAPOKTAN (Gabungan Kelompok Tani). Masalah yang dihadapi oleh para petani Gapoktan ialah sering memperkirakan kondisi tanah hanya dengan cara melihat keadaan tanah dan tanaman padinya saja. Hal tersebut bisa mempengaruhi pertumbuhan tanaman kurang maksimal dan tumbuhnya jamur serta bakteri. Dikarenakan unsur hara yang terdapat pada tanah bisa hanyut oleh air jika para petani tidak memperhatikan kelembapan tanah. Selain itu, para petani sering memperkirakan waktu pemupukan. Dimana bila tanah dalam kondisi kering pupuk tidak dapat dilakukan harus menunggu lahan menjadi lembab. Hal tersebut bisa mempengaruhi penyerapan pupuk kurang maksimal. Mengacu pada latar belakang tersebut penulis mempunyai gagasan pada Tugas Akhirnya untuk membuat  “Rancang Bangun Alat Ukur Kelembapan Tanah Menggunakan Sensor Soil Moisture Untuk Tamanan”. Teknologi tersebut akan diterapkan pada sebuah prototype. Pengembangan sistem ini diharapkan mampu mempermudah para petani untuk mengetahui kadar kelembapan pada tanah pesawahan dan waktu  pemupukan, khususnya pada sawah para anggota Gapoktan Dukuh Tambakroto.

Stroke is the number one cause of disability and the second cause of death in the world. Blood flow that is not smooth in stroke patients causes hemodynamic disorders including changes in the value of oxygen saturation in the blood (SpO2) which can interfere with the function of internal organs including the heart due to lack of oxygen intake. So we need a system to monitor the oxygen saturation value which can be used as an early indicator in recognizing stroke patients. This system uses detection of two sensors to measure oxygen saturation in the blood, a microcontroller to process data, a monitor to display data, a buzzer as a warning of the lower limit of measurement and a micro sd card module to store measurement data that has been running. Parameters displayed include the date of measurement, patient ID, SpO2-1, SpO2-2, last SpO2-1 and last SpO2-2. This system will measure and display the SpO2 value of both right and left arms simultaneously. Stroke patients who experience muscle weakness in one hand may experience different values with a hand that does not experience muscle weakness. This study aims to develop an SpO2 monitoring system that will be used to detect stroke patients with non-invasive methods. The results show that the system has been developed and can be used to measure the patient's SpO2 from both hands simultaneously with a measurement error rate of ±2% for each sensor from standard medical equipment.

Water is very important for all aspects of life on earth, agriculture is one of the fields that really need large amounts of water because of the use of water in the process of plant photosynthesis. Water that has good quality is if the water is not excessively polluted by harmful chemicals or minerals. One indicator that water is polluted is a change in temperature and pH (acidity) of the water. Temperatures that are too hot in the water will interfere with the growth of plants and other microorganisms. While the normal pH of water has a pH that ranges from 6.5 to 7.5. The quality of water and soil is very important in agriculture. The level of acidity (pH) and soil temperature are one of the things that affect plant fertility. Therefore, the quality of water and soil on agricultural land is one of the important things that needs special attention in its management. One solution so that water and soil quality can be monitored and managed efficiently is to utilize a Wireless Sensor Network based on the Internet of Things (IoT). The use of the ESP8266 Module as a WIFI module, is widely used by Internet of Things-based applications because the price is cheap so it reduces a lot of costs and has a fairly good speed of 80 MHz. This study aims to develop the concept of a Wireless Sensor Network by utilizing the ESP8266 module to monitor pH values using a pH Meter Analog Kit sensor and temperature from agricultural land using a DS18B20 Waterproof sensor and can be monitored at any time using a smartphone.
