Abstract

Ni-Fe alloy thin film on Cu substrate by electro-deposition method has been made without as well as with agitation of 300 rpm for a 3 minutes deposition time and potential of 3 Volt. The characterizations consist of crystal structure test by X-Ray Diffraction method, morphology and composition test by SEM/EDX and magnetoresistance measurement with two-point probes equipment. Result of the XRD test showed that the growth of crystal structure was in the same orientation on 111, 200, 220, 311with structure of fcc. Morphology test showed that the structural images of Ni-Fe surface thin film on agitation became flat and had less grain size. The composition test results showed that composition with agitation closely Ni80Fe20 (permalloy) was 87.51% for Ni and 12.49% for Fe. The magnetoresistance measurement was less with the agitation treatment i.e. without agitation was 9.1 % and with agitation was 1.9 %.

Abstract

This study aims to investigate the effect of nickel doping into chlorophyll dye on the optical properties and conductivity for DSSC application. The nickel doping is focused the effect of nickel concentration into chlorophyll dye as photosensitizer. Analysis of optical properties (absorbance) of dye solutions and TiO2 used the UV-Visible spectrophotometer. The conductivity of dye solutions were calculated using I-V meter. The characterization results of absorbance and conductivity of dye solutions were direcly proportional to increasing the Ni concentration. The FTIR characterization resulted the optimum absorption at a concentration of 0,1 M with the frequency peak of (Ni-Cl) at 679 cm-1. The absorbance of TiO2/dye also showed that the optimum doping concentration of 0,1 M.

Abstract

Shallots one of a leading vegetable commodity in Central Java. However, the shallot farming industry is frequently confronted with the issue of decreasing yields due to the presence of plant pests. Onion plant pests include the butterfly (Spodoptera exigua) and the leafminer fly (liriomyza). There are two approaches to dealing with this pest problem: pesticides/insecticides and light traps. In terms of organic farming methods, the use of light traps is more profitable. However, the operational costs are quite high because farmers must have a generator to generate electricity, diesel fuel to turn on the generator, oil to lubricate the engine, operators, or must connect to the PLN electricity network. So, we used a solar-powered pest trap lamp system with Li-ion batteries as the energy storage medium to solve this problem. In Srimulyo village, Gondang district, Sragen regency, community service activities such as installing pest trap lights to control pests on shallots were carried out. The onion farmer group association is the service activity's partner (Gapoktan). This activity was well received by shallot farmers because the presence of this light trap can reduce pest attacks.

Abstract

Sampah selalu menjadi permasalahan yang tak kunjung usai dan menjadi perhatian serius pemerintah Indonesia. Kesadaran masyarakat Indonesia dalam pengelolaan sampah masih harus terus ditingkatkan. Secara umum sampah dapat dikategorikan sebagai sampah organik dan non organik. Kedua jenis sampah tersebut sejatinya dapat dimanfaatkan lagi. Sebagai contoh dengan mendaur ulang sampah plastik menjadi barang-barang yang bermanfaat seperti vas bunga, pot, tempat pensil dan lain sebagainya Sedangkan sampah organik dapat dimanfaatkan untuk membuat pupuk kompos atau bahkan untuk sampah organik dalam jumlah banyak dapat dimanfaatkan sebagai sumber energi baru biogas. Oleh karenanya dalam usulan pengabdian ini, akan dilakukan edukasi pengelolaan sampah organik di Yayasan Pendidikan Mutiara Insan Sukoharjo. Yayasan Pendidikan Mutiara Insan membawahi beberapa institusi pendidikan yaitu SMPIT Mutiara Insan, SDIT Mutiara Insan dan TKIT/PAUD Mutiara Insan. Sebagai lembaga Pendidikan dengan kurikulum fullday, yayasan menerapkan kebijakan pemberian katering snack maupun makan siang setiap harinya. Selain berdampak positif, hal tersebut tentunya menimbulkan masalah karena banyaknya sampah organik yang berasal dari potongan sayuran maupun sisa makanan siswa. Berdasarkan latar belakang tersebut, maka diperlukan edukasi untuk membangun kesadaran pengelolaan sampah organik tersebut. Edukasi dengan pemberian materi in class tentang pengelolaan sampah menjadi energi alternatif biogas. Kegiatan diikuti oleh pemangku kebijakan dari Yayasan Mutiara Insan dan juga perwakilan pemerintah setempat. Dari hasil pelatihan, peserta merasa mendapatkan pencerahan mengenai sampah organik sebagai sumber energi alternatif dan siap mendukung penerapannya di Yayasan Mutiara Insan sebagai usaha mewujudkan sekolah yang berwawasan mandiir energi. Dari pengabdian ini diharapkan masyarakat mendapatkan kemanfaatan edukasi dan teknologi tepat guna dalam usaha pengelolaan sampah khususnya sampah organik.
