Abstract

This volunteer work is being done in Klino Bojonegoro, more specifically in the Bojonegoro and Madiun border region. By supplying IOT-based automatic plant sprinklers for watering the local chrysanthemum horticulture, this PKM activity serves to support farmer organizations in the community. Chrysanthemum and rose picking excursions are one of the tourist attractions in Klino Village, one of the tourist destinations in Bojonegoro. The female farmer organization Blooming Sari is in charge of managing the chrysanthemum cultivation (KTW). Using hoses and padlocks, traditional watering procedures are still used, and they are done in the morning and evening. The approach used in this program is to have casual, one-on-one conversations with farmer groups, followed by observations of field requirements and the creation of tools. The stages of activities completed include site surveys, tool and material analysis, tool creation, tool testing, socialization, monitoring, and PKM program evaluation. This PKM activity resulted to the creation of an IOT-based, smartphone-controllable automatic plant watering solution. There are a number of challenges, including those in tool manufacturing that necessitate numerous trials, pipe installation that requires pipes to match the position point, network limitations, and others. This leads to the conclusion that this PKM activity is effective, capable of resolving issues, and perhaps a solution to the issues facing farmer groups in Klino Bojonegoro village.

Abstract

Polyaniline is a polymer material that has unique physical and even chemical properties, especially in its electrical properties. PANi synthesis can be carried out by chemical and electrochemical oxide reaction methods. The purposes of this study are to synthesize PANi and PANi / Fe3O4 composites by chemical oxide reactions and measure their conductivity. This research begins with the synthesis of iron oxide (Fe3O4) from natural iron sand and then followed by the synthesis of PANi / Fe3O4 composites using copreticipitation method. The Fe3O4 crystal phase was determined by using XRD, while the vibrational mode and morphology of the PANi / Fe3O4 nanocomposite was observed using FTIR and SEM. The conductivity properties were measured using a LCR meter. Furthermore, the conductivity properties were measured using a LCR meter and the result reveals a greater conductivity value as increasing the concentration of Fe3O4, the highest conductivity value of 3.1 mS/cm is known by the sample with an iron oxide concentration of 1 %. While the samples with a concentration of 0.5 % of iron oxide has conductivity values  of 2.8 mS/cm and pure PANi of 2.1 mS/cm. Due to its properties such  to inert to the environment and having conductive properties, the obtained PANI / Fe3O4 composite can be employed as a super capacitor electrode.

Abstract

Pada beberapa jenis buah-buahan seperti buah belimbing memiliki kandungan zat kimia aktif yang dapat diubah menjadi energi listrik. Proses yang dapat dilakukan yakni melalui reaksi reduksi dan oksidasi yang terjadi pada kedua elektroda. Tujuan dari dua konduktor, ketika Cu dan Zn dihubungkan melalui larutan elektrolit dapat membentuk rangkaian menjadi sel volta. Tegangan muncul sebagai akibat reaksi kimia di kedua elektroda. Sedangkan elektroda positif (Cu) mengalami reaksi reduksi, selanjutnya elektroda negatif (Zn) akan mengalami reaksi oksidasi, sehingga elektron mengalir dari seng ke tembaga. Penelitian ini difokuskan pada pengujian buah belimbing (Averrhoa carambola) sebagai larutan elektrolit. Jenis rangkaian seri pararel digunakan sebagai variasi dalam penelitian ini. Sel volta digunakan sebanyak 10 sel untuk menghasilkan tegangan dan arus maksimal. Sel volta buah belimbing dibuat dengan cara merangkai kerangka sel volta dengan kabel dan LED serta diuji dengan voltmeter dan amperemeter. Telah didapatkan pada sel volta belimbing matang dirangkai secara seri menghasilkan tegangan sebesar 4,2 V dan arus 0,2 mA sedangkan jika dirangkai secara pararel menghasilkan tegangan 0,6 V dan arus 1,05 mA. Pada uji ketahanan dengan rangkaian seri, sel volta buah belimbing mampu menyalakan lampu LED hingga 9 hari. Sel volta ini dapat menghasilkan listrik dengan elektroda Cu dan Zn yang tergantung pada kondisi elektrolit
