Abstract

Nilai resistansi tanah tanaman terkait dengan kandungan air dalam tanah dalam kondisi tercukupi atau mengalami kekeringan air. Ketika kandungan air dalam tanah tanaman berkurang, maka dapat menyebabkan tanaman akan menjadi layu. Pada penelitian ini dilakukan pengujian kondisi air tanah tanaman kondisi tercukupi atau mengalami kekeringan berdasarkan nilai resistansi tanah tanaman tersebut. Hasil pengujian pada tanah tanaman berada dalam wadah berbentuk empat persegi panjang memiliki dimensi parameter panjang,  lebar dan tinggi dalam satuan centi-meter. Hasil penelitian pada tanah tanaman berada dalam wadah tersebut dalam kondisi kandungan air tanah tercukupi nilai resistansi tanah R(t.c) = 40,5 kOhm. Kondisi tanah tanaman mengalami kekeringan air nilai resistansi tanah parameter R(t.k) = 51,2 kOhm. Indikasi kandungan air tanah tanaman mengalami kekeringan air saklar elektronik dari peralatan rangkaian elektronika mengaktifkan suara bunyi buzzer. Kemudian dilakukan penyiraman air kedalam wadah tanah tanaman yang  mengalami  kekeringan air tersebut untuk menghindarkan tanaman menjadi layu, maka saklar elektronika menonaktifkan kondisi buzzer menjadi tidak bunyi.

Abstract

The maximum solar cell power capacity without load parameter Pm(no-load) = 0.4 watts is used to supply an external electrical load with a resistor R in ohms. Irradiation of the solar cell surface area during the day in bright sunlight supplies an electrical load with a resistor R = 100 Ω which absorbs solar cell power with parameters Psel(R) = 0.09 watts. The power efficiency of a solar cell loaded with a resistor R is expressed as the parameter eff.sel(R) which is the result of a comparison between the power Psel(R) = 0.09 watts and the power Pm(no-load) resulting in a value of eff.sel(R) = 22.5% . Achieving solar cell to more effectively supply a resistor load of R = 100 Ω is efficiency done by adding a parallel FC-75 type dc-dc buck converter device to the solar cell output. Test results: The input power of the FC-75 dc-dc buck converter is Pi(conv.) = 0.178 watts. The resistor load R absorbs the output power Po[conv.(R)] = 0.078 watts. The power efficiency of solar cells using a dc-dc buck converter is expressed as the eff.sel(conv.) parameter. The results of the comparison between the power Po[conv.(R)] and the power Pi(conv.) reach 43.82%. The achieved power efficiency results for solar cells supplying resistor load R using a dc-dc buck converter are eff.sel(conv.) = 43.82%, which is greater than eff.sel(R) = 22.5%.

Abstract

Mobile phone (HP) battery manufacturing specifications have a charging current capacity maximum parameter CAh(maks.) = 800 mAh and maximum voltage Vbat(max.) = 3.7 volts dc reduces to 2.02 volts dc requires recharging. In this research HP battery voltage was recharged using the FC75 dc-dc buck converter method, starting from a voltage of Vbat(initial) = 2.02 volts until the final battery voltage was charged at Vbat(final) = 3.713 volts. The HP battery charge voltage parameter Vch comes from the output voltage of the FC75 dc-dc buck converter the parameter Vo(conv.) is expressed as Vo(conv.) = Vch. The purpose of using the FC75 dc-dc buck converter is to electronically convert the lower Vo(conv.) charger voltage (buck) to the larger Vi(conv.) input voltage to control the HP battery charger output power equal to the input power. The results of the research on controlling the output power of the HP battery charger of Po(conv.) = Pi(conv.) = 0.579 watts, there was an increase in the final charger voltage Vokonv.(final) along with the increase in the final HP battery voltage Vbat(final) being charged. The increase in the final charger voltage reaches Vokonv.(final) = Vbat(final) = 3.713 volts, the final charger current becomes Ich(final) = 0.156 A and remains towards the HP battery during charging with a difference in the decrease in charger current towards the HP battery of ∆Ich = 0.009 A relatively small is still profitable, because it avoids back current to the charger voltage.

Abstract

This community service activity provided counseling to 24 class XII IPA1 students at Mater Dei High School, Pamulang sub-district, South Tangerang municipality. The counseling aims to know, understand and understand the use of PLTS using solar cells which produce a direct/DC output voltage to supply light bulbs when they are on. The counseling method for students to understand PLTS scientific material is theoretically presented in the classroom for 90 minutes. Then proceed to find out and understand the benefits of PLTS using solar cells to produce output voltage to supply light bulbs when they are on outside the classroom. The extension activity of illuminating the surface area of ​​solar cells with sunlight outside the classroom for 90 minutes is carried out by five (5) students per group taking turns accompanied by members of the extension team with the aim of practical knowledge and understanding. Each group of students takes an average of 16 minutes to shine sunlight on the surface area of ​​the solar cell which produces electrical power when the light bulb is on or off. The results of the implementation of counseling on the condition of the light bulb is on, the voltage value on the lamp load is Vb(lamp) = 4.46 volts when bright sunlight shines on the surface area of ​​the solar cell. Then, if the light bulb does not light up, the voltage value on the light load changes to 0.351 volts, when sunlight is blocked or blocked from reaching the surface area of ​​the solar cell. The results of the outreach activities were 24 students responding to six (6) questions with multiple choice answers listed on the questionnaire form that had been prepared. A total of 23 people chose useful answers to the content of the material presented, a total of 22 people chose interesting answers to questions about the material presented by the speaker and as many as 21 people chose useful answers for the entire extension activity event.
