Information systems are created in stores in order to easily process data and produce the information needed quickly, accurately, precisely, effectively, and efficiently, reducing spending costs. The purpose of this study is to produce a forecasting system for tempeh demand to suit consumer needs when marketed. This type of research is research and development using the waterfall model. This model consists of stages of analysis, design, implementation, and testing. The analysis was conducted to obtain the needed data regarding tempeh using the weighted moving average (WMA) method. While we make this design, such as flowcharts, use cases, and data flow diagrams, Furthermore, the implementation of the women's tempeh factory was carried out, and testing was carried out using black box testing. The data we use is request data from September 29, 2023, to December 23, 2023. Our findings show that the mean absolute percentage error (MAPE) to predict tempeh demand is 3.83%; this result is quite small, so the accuracy rate obtained is 96.17%. In addition, the results of the system we developed are also in accordance with the results of manual calculations. This is also evidenced by the absence of errors that occur after testing using black box testing. So that this system can be used to manage tempeh, it is ready to be marketed by the female tempeh factory.

Abstract: Due to the successful conversion from LPG stoves to electric stoves, which are unsupported by the village’s electricity supply—averaging 450 watts—while government-provided stoves have a power rating of 900 watts, making them unsuitable for use in Tomuanhollbung Village. To address this issue, the research team designed a stove that uses waste oil (35,000 kJ/kg) and incorporated embedded system technology, utilizing the French design research method. The research results indicated that by using a DC motor with specifications of 12VDC/3A, 3800 rpm, and a valve diameter of 9.7 x 9.5 x 3.3 cm, a power output of 36W was achieved, with a pressure of 288.7 Pa or 0.00289 bar and an angular velocity of 398.1 rad/s. When the burner stove was first ignited, the flame appeared yellow. With a voltage of 3.7VDC/3A, it produced a rotation of 3795 rpm, a yellow flame, a flame height of 8 cm from the stove, and a flame width diameter of approximately 18 cm. At a voltage of 3.7VDC, the pressure measured 0.000964 bar, with a flame temperature of 275°C (as measured by an infrared sensor). A voltage of 7.4VDC resulted in a pressure of 0.0192 bar and a flame temperature of 350°C, while a voltage of 11.8VDC produced a pressure of 0.0289 bar with a maximum flame temperature of 420°C. For fuel consumption over 10 minutes at 3.7VDC/3A, the flame height reached 7-10 cm, with a wind pressure of 0.000964 bar and a fuel consumption of 0.237 grams. Keywords : embedded system burner stove; microcontroller; snail dc motor.

Clean water is one of the necessities for humans, especially to meet the washing needs of families. Most of the population in the Asahan district still uses drilled well water as a source of clean water to meet their water needs. The results from inhalation of water will also be filtered, and usually, within 30 minutes, the water will turn yellow again. During this time, the cleaning of the water filtering container is cleaned every 1 - 2 weeks, with a long cleaning time of 30 minutes to 1 hour. From the field study, the research team designed a filter by utilizing six paralon pipes with a size of 3.5 inc, 1 m long, with a clarification module for each pipe, starting from the first pipe with spongy media, the second pipe for gravel media, the third medium, soil, and sand. The fourth media is charcoal, the fifth media, and the sixth paralon, and the sixth media is palm fiber. The results of the water reading in the first pipe to the fourth pipe found the ph of water at an index of 5-6 ph, with an average sensor output voltage value of 4787 mV. The sensor supply and the pH reader controller use a 7.4 VDC supply voltage and a 5VDC / 5A.

The design of a lighting automation system for dragon fruit plants uses an LDR sensor as a light intensity detector. This system is supported by a solar module with a capacity of 10-20 watts to supply power to a 12V battery which is paralleled to 24V. This voltage was then changed by the inverter to 220VAC to light 10 lights as research samples. Tests show that the LDR sensor works optimally at 5VDC voltage. If the voltage supplied is less or more than 5VDC, the sensor cannot function properly. Analysis of the conversion of ADC values to output voltage shows consistent results according to the test table. In addition, using 12VDC voltage directly on the LDR causes the sensor to not function because the LDR is designed for low voltage (≤5V). Without a suitable resistor, excessive current can damage sensor components. The system design is able to minimize the use of electricity sources from PLN and is an energy-saving solution for lighting dragon fruit plants in the field. Keywords: agriculture sustainable; dragon fruit trees; photosynthesis; renewable energy;solar cells Abstrak: Rancangan sistem otomatisasi lampu pada tanaman buah naga menggunakan sensor LDR sebagai pendeteksi intensitas cahaya. Sistem ini didukung oleh modul surya berkapasitas 10-20 watt untuk menyuplai daya ke baterai 12V yang diparalel menjadi 24V. Tegangan ini kemudian diubah oleh inverter menjadi 220VAC untuk menyalakan 10 lampu sebagai sampel penelitian. Pengujian menunjukkan bahwa sensor LDR bekerja optimal pada tegangan 5VDC. Jika tegangan yang diberikan kurang atau lebih dari 5VDC, sensor tidak dapat berfungsi dengan baik. Analisis konversi nilai ADC ke tegangan output menunjukkan hasil yang konsisten sesuai tabel pengujian. Selain itu, penggunaan tegangan 12VDC langsung pada LDR menyebabkan sensor tidak berfungsi karena LDR dirancang untuk tegangan rendah (≤5V). Tanpa resistor yang sesuai, arus yang berlebih dapat merusak komponen sensor. Rancangan sistem mampu meminimalisir penggunaan sumber listrik dari PLN dan menjadi solusi hemat energi untuk penerangan tanaman buah naga di lapangan.

Oral health problems are more vulnerable in children with disabilities than children in general. One of the efforts to minimize these problems is to increase parents' awareness of the importance of maintaining effective oral health in children with disabilities. Therefore, it is necessary to increase the knowledge and skills of parents who have children with disabilities in the early detection of oral health problems so that severity does not occur. This community service program is in the form of socialization activities and early detection skills training conducted for 71 parents/caregivers on 20 September 2024 at the RSGMP Baiturrahmah Hall, Padang City. Pre and post-assessment of parents' knowledge and skills were conducted, out of 72 parents/caregivers only 39 parents/caregivers completed the pre and post-test. The results of the analysis of existing data showed a significant increase in both the knowledge and skills of parents in the early detection of oral health problems. This activity needs to be carried out regularly as a promotional effort to improve the degree of oral health in children with disabilities.

Abstract: This study aims to improve the growth of Pakcoy (Brassica rapa L.) plants through environmental monitoring and control using a pH sensor, LM35 temperature sensor, and air humidity sensor within a hydroponic planting system. The methodology involves designing an automatic monitoring system based on a microcontroller integrated with the three sensors. The pH sensor monitors the acidity level of the nutrient solution, the LM35 measures ambient temperature, and the humidity sensor records the relative air humidity around the plants. Data were collected periodically and analyzed in relation to plant growth parameters such as height, number of leaves, and leaf color over a 30-day cultivation period. The results show that the sensor-based monitoring system successfully maintained environmental parameters within optimal ranges, positively impacting Pakcoy plant growth, with an average height increase of 18% compared to a system without automatic control. The study concludes that the integrated use of pH, LM35, and humidity sensors in a hydroponic system significantly enhances cultivation efficiency and plant growth quality.
