Abstract

ABSTRAKDalam praktiknya, banyak ruangan yang tidak memiliki ventilasi cahaya sehingga menggunakan sumber cahaya hingga selama 24 jam. Penelitian ini bertujuan untuk merancang sistem yang dapat meminimalkan penggunaan listrik untuk penerangan dengan menggunakan sistem solatube. Solatube akan memberikan sinyal pada dimmer yang mengatur kapasitas cahaya lampu sehingga tidak selalu membutuhkan performa penuh. Berdasarkan hasil pengujian, sistem solatube dapat menghasilkan nilai intensitas cahaya maksimal yang dapat memenuhi standar untuk ruang baca yaitu lebih dari 350 Lux dengan persentase penerangan menjadi hanya 1% - 79%, terutama selama penggunaan beban siang hari. Hal ini menunjukkan bahwa dengan penggunaan solatube penggunaan daya untuk penerangan dapat dikurangi, sehingga meningkatkan penghematan energi dan biaya. Kemudian alat ini dilengkapi dengan data logger yang dapat diakses melalui internet untuk memantau penggunaan listrik secara realtime sehingga dapat dilakukan monitoring dan evaluasi untuk pengembangan selanjutnya.Kata kunci: Sistem Pencahayaan, Solatube, Penghematan Energi, Data Logger. ABSTRACTIn practice, many rooms do not have light ventilation, so they use light sources for up to 24 hours. This study aims to design a sistem that can minimize the use of electricity for lighting using a solatube sistem. Solatube provide a signal to the dimmer that regulates the light capacity of the lamp thus it does not always require full performance. Based on the test results, the solatube sistem can produce a maximum light intensity value that can meet the standards for the reading room, which is more than 350 Lux with the percentage of light being only 1% - 79%, especially during the use of daytime loads. This shows that with solatube lighting sistem, power consumption for lighting can be reduced, thereby increasing energy and cost savings. Furthermore this tool is equipped with a data logger that can be accessed via the internet to monitor realtime electricity usage thus that it can be monitored and evaluated for further developmentKeywords: lighting sistem, solatube, energy saving, data logger.

ABSTRAKPotential of Hydrogen (pH) adalah salah satu parameter penting yang terdapat pada nutrisi tanaman hidroponik. Setiap tanaman memerlukan nutrisi dengan pH sesuai kebutuhannya, agar dapat tumbuh dengan baik. pH nutrisi akan berubah setiap saat, sehingga perlu sering dipantau. Terdapat kendala pada pH meter yang digunakan saat ini, misalnya perlu kalibrasi ulang jika digunakan lebih dari 24 Jam karena elektroda sensor pH rentan terhadap larutan yang diukurnya. Pada penelitian ini dirancang sebuah pH meter cerdas yang akan digunakan untuk mengukur nutrisi tanaman. Alat ukur ini mampu digunakan secara terus menerus selama lebih dari 24 jam. Sensor pH yang digunakan adalah FIT0348 dan ATMega8 sebagai unit kontrolernya. Proses pengujian terdiri dari 4 tahap. Berdasarkan hasil pengujian, disimpulkan bahwa koefisien determinasi pada rangkaian pengkondisi sinyal yang dirancang telah linier yaitu 0,9999 dengan persamaan regresi y=0,0065x+6,189. ΔpH dari pH meter yang dirancang adalah ±0,01 dengan menggunakan PH/EC-9853 sebagai alat ukur pembandingnya.Kata kunci: potensial of hydrogen, pH meter, hidroponik, nutrisi tanamanABSTRACTPotential of Hydrogen (pH) is one of the important parameters found in hydroponic plant nutrition. Every plant needs nutrients with pH according to their needs, so they can grow well. The pH of nutrients will change at any time, so it needs to be monitored frequently. There is a problem with the pH meter used today, for example, it needs recalibration if it is used more than 24 hours because the pH sensor electrode is susceptible to the solution it measures. In this study, a smart pH meter was designed to be used to measure plant nutrient. This measuring instrument can be used continuously for more than 24 hours. The pH sensor used is FIT0348 and ATMega8 as the controller unit. The testing process consists of 4 steps. Based on tests, it was concluded that the coefficient of determination in the signal conditioning circuit designed was equal to 0.9999 with the regression equation y = 0.0065x + 6.189. ΔpH from the pH meter designed is ± 0.01 by using PH/EC-9853 as a comparison measuring instrument.Keywords: potensial of hydrogen, pH meter, hydroponic, plant nutrition

Abstract

Compost fertilizer is a type of fertilizer used by the Nur Alam community to enrich their agricultural land. This fertilizer is needed in large quantities every week. In this community service activity, a composting machine was created to assist Nur Alam Tani with their fertilizer needs. The function of this machine is to accelerate the compost production process by shredding waste into smaller sizes. The machine has dimensions of 490 x 455 x 950 mm. An electric motor with a power specification of 1Hp is used as its drive. This machine is capable of processing waste at a rate of 5 kg/hour, producing shredded material with an approximate size of 10 mm. The output from this machine has greatly benefited Nur Alam Tani, as prior to the use of this device, they were only able to produce about 10 kg of fertilizer per week.

Abstract

Hydroponics is a farming technique that has many advantages. This system has many types, for example the Nutrient Film Technique (NFT). In this activity, an NFT hydroponic system based on automation is created for parameter settings that affect plant growth. Several parameters are controlled, such as pH and TDS on plant nutrition, as well as humidity and air temperature in the environment. This system was placed in Ciparay village to help the community learn hydroponic farming. As a result of this activity, the entire system can work well, but there are still some leaks. After this system worked, socialization activities were carried out to the Ciparay community to explain how to use the system for hydroponic cultivation.
