Abstract

Sel surya berbasis DSSC memiliki peluang untuk dikembangkan karena proses fabrikasinya yang sederhana, biaya murah, serta berbahan dasar organik. Pembuatan DSSC dengan memanfaatkan pigmen tumbuhan murni seperti β-karoten dan menggukanan TiO2 sebagai fotoanoda. Karaterisasi DSSC dilakukan melalui pengukuran I-V dibawah pencahayaan 1000 W/m2, dengan analisis dilakukan melalui fitting nonlinier dari persamaan Shockley untuk mendapatkan seluruh parameter sel surya seperti n, Rs, Rsh, Io, Iscdan Voc.

Abstract

Dye Sensitized Solar Cell (DSSC) merupakan salah satu bagian dari energi terbarukan yang memiliki potensi besar dengan memanfaatkan energi dari sinar matahari menjadi energi listrik dengan bantuan sensitizer sebagai agen penyerap cahaya. Kemampuan konversi DSSC ditunjukkan oleh nilai Jsc (12,70 mA/cm2), Voc (0,585 V), FF (0,476), dan η (3,54%) yang diperoleh dari pengujian solar simulator. Selain parameter tersebut, karakteristik DSSC dapat juga ditunjukkan dari nilai ttr (0,010 s), trec (0,080 s), ηcc (0,874), D (0,192) dan  LD  (0,124 mm) melalui IMPS (Intensity Modulated Photocurrent Spectroscopy) dan IMVS (Intensity Modulated Photovoltage Spectroscopy). Pada artikel ini juga dilaporkan Impedansi antar lapisan DSSC melalui analisis EIS (Electrochemical Impedance Spectroscopy). DOI: http://dx.doi.org/10.17977/um024v4i12019p023

Abstract

Penggunaan energi terbarukan berbasis energi matahari banyak dikembangkan dalam beberapa tahun terakhir berupa solar sel khususnya dalam bentuk DSSC. Semikonduktor SnO2 memiliki band gap yang paling besar yaitu 3,6 eV dan TiO2 dalam bentuk anatase dan rutil memiliki nilai 3,2 dan 3,0 eV. SnO2 dan TiO2 memiliki beberapa kemiripan pada sifat elektronik dan struktural. Pada penelitian ini, pembentukan komposit TiO2/SnO2 dilakukan dengan menggunakan variasi Wt% massa TiO2 100, 97, 94, 88  dan 85%. Metode dalam sintesis menggunakan kopresipitasi untuk TiO2 dan solgel untuk SnO2. Karaktersisasi XRD menunjukkan nano partikel TiO2 dengan struktur anatase dengan ukuran butir 8,89 nm dan nano partikel SnO2 28 nm. Pada variasi massa, efisiensi meningkat dengan bertambahnya massa TiO2. Nilai efisiensi maksimum yang dihasilkan pada 100 % TiO2 yaitu 0,18 %. DOI: http://dx.doi.org/10.17977/um024v3i22018p063

Abstract

Pengenalan Panel Surya sebagai Sistem Energi Terbarukan untuk siswa SMA di Kalimantan Tengah. Khususnya Palangka Raya dapat menjadi upaya mendukung terwujudnya program Sustainable Development Goals (SDGs). Tim telah melakukan diskusi secara daring dengan pihak mitra yaitu SMAN 6 Palangka Raya untuk melaksanakan pengenalan Panel surya sebagai sistem energi terbarukan pada siswa di SMAN 6 Palangka Raya. Sekolah ini berlokasi di Jl. Tjilik Riwut KM29, kelurahan Tumbang Tahai, kecamatan Bukit Batu, kota Palangka Raya, Kalimantan Tengah. Tim membuat suatu kegiatan edukasi kepada siswa yaitu demo konversi energi surya menjadi energi listrik. Pelaksanaan pengabdian masyarakat ini telah terlaksana dengan baik. Siswa sangat antusias dalam belajar mengenal panel surya dan komponen-komponen elektronika yang digunakan secara langsung.

Abstract

Abstrak: Green economy merupakan salah satu jenis ekonomi yang memperhatikan aspek lingkungan. Konsep green economy melibatkan pemanfaatan tanaman sebagai sumber daya terbarukan dalam bidang ekonomi. Sebagai kabupaten yang baru keluar dari status 3T, Seruyan memiliki potensi pengembangan ekonomi dalam bidang green economy. Pengabdian ini bertujuan mengenalkan green economy melalui transfer teknologi destilasi minyak atsiri dengan tanaman yang digunakan adalah Serai Wangi yang lazim ditemukan di Desa Bukit Buluh. Metode pelaksanaan pengabdian terdiri dari merancang alat destilasi dan pelatihan pemanfaatan alat destilasi yang dihadiri 23 peserta dari warga dan pengurus desa dengan peningkatan pemahaman dalam bidang rangkaian distilasi, pemilihan tanaman, dan optimasi ekstraksi sebanyak 95, 60, dan 85 %. Kegiatan pengabdian ini berjalan dengan baik dengan tingginya antusiasme warga dalam kegiatan pelatihan.Abstract: Green economy is an economic model that prioritizes environmental considerations. The concept of the green economy revolves around utilizing plants as renewable resources within the economic sector. Seruyan, recently emerged from 3T status, holds substantial potential for economic growth within the realm of the green economy. The purpose of this initiative is to introduce the principles of a green economy by imparting knowledge about essential oil distillation technology, using Lemongrass as the primary plant source, abundantly available in Bukit Buluh Village. The method of implementing the service consisted of designing distillation equipment and training on the utilization of distillation equipment which was attended by 23 participants from residents and village administrators with an increase in understanding in the fields of distillation circuit, plant selection, and extraction optimization by 95, 60, and 85%. This service activity went well with the high enthusiasm of the residents in the training activities.

Abstract

The issue of environmental pollution has become a concern, especially for the government, since the establishment of Law No. 4 of 1982. This is because the effects of pollution can be toxic and even fatal for living beings, particularly humans. One of the pollutants in the environment generated from mining industry waste is heavy metal Fe. In light of these problems, a study was conducted to investigate the effectiveness of sawdust and Moringa twigs as by-products in adsorbing heavy metal iron (Fe) in the liquid waste of the gold mining industry. This research is classified as pure experimental research. The research reveals that the mean percentage reduction in the heavy metal iron (Fe) content in the gold mining industry wastewater, after treatment with the addition of Moringa leaf powder, is 9.6%. On the other hand, treatment with the addition of Moringa stem powder achieves a reduction of 92%. This significant difference is attributed to the bioactive compound rhamnosyloxy-benzyl isothiocyanate present in Moringa. This compound has the ability to adsorb and neutralize sludge and metal particles found in the waste suspension, along with dirt particles in the water. Consequently, Moringa shows potential as a natural coagulant for water purification purposes.

Abstract

Karamunting (Melastoma malabathricum L.) contains several compounds with pharmacological activities including antioxidant, analgesic, anti-inflammatory, antipyretic and diuretic. Karamunting flowers contain flavonoid compounds, saponins and tannins. Tannin compounds can stabilize free radicals by complementing the electron deficiency of free radicals. To increase the utilization of karamunting flowers, it is formulated in the form of effervescent granules. This study aims to determine the ethanol extract of karamunting flower (Melastoma malabathricum L.) with concentrations of 1%, 2%, and 3% can be formulated in the form of effervescent granules. The physical properties of the granules were tested which included organoleptic test, flow rate test, granule compressibility test, dissolving time test and pH of effervescent granules. The results showed that formula 3 with a concentration ratio of 3% ethanol extract was a formula that met the requirements for the physical properties of the granules, namely with a sweet and sour taste, a characteristic odor of karamunting, and a dark purple-brown color. With an average flow rate of 2.853 g/sec, average compressibility of 21.12%, an average dissolving time of 7.52 seconds and a pH measurement of 5.
