Wisaksono, M. A., Tamrin, T., Pratama, F. (2024). The utilization of fiber tissue as an electrolyte absorbent of Dye Sensitized Solar Cell. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 634–648). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dye-Sensitized Solar Cells represent a set of photoelectrochemical solar cells capable of converting light energy into electrical energy by harnessing plant-derived dyes as light sensitizer. One of the factors influencing the performance of a DSSC is the electrolyte. The addition of a fiber tissue layer to DSSCs can reduce evaporation in the electrolyte solution. The fiber tissue layers used in this study were derived from facial tissue. The objective of this research is to study and understand the impact of varying thicknesses of fiber tissue layers as electrolyte absorption media on the performance of Dye-Sensitized Solar Cells. This research was conducted from September 2023 to December 2023 at the Energy and Electrification Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Universitas Sriwijaya. The study comprised of three stages: DSSC structure preparation, assembly and arrangement of DSSC layers, and DSSC measurements. The thickness variations of the fiber tissue layers used were two layers (0,027 cm), three layers (0,041 cm), four layers (0,054 cm), five layers (0,068 cm), six layers (0,081 cm), and a control without fiber tissue layer applied to water hyacinth leaf dye and senduduk fruit dye. Parameters observed in this study included current and voltage characteristics, power calculations, fill factor, and DSSC efficiency. The results indicated that DSSCs with an additional fiber tissue layer exhibited relatively better performance compared to DSSCs without the additional fiber tissue layer, both in the senduduk fruit dye and water hyacinth dye.. The DSSC performance was most prominent in the senduduk fruit dye sample with a four-layer (0.054 cm) thickness of fiber tissue layer. The electrical characteristics produced by this sample were Isc:  0,016 mA, Voc:  0,682 mV, Imax:  0,011 mA, Vmax:  0,397 mV, Pmax:  0,00417 mW, FF:  0,37924, and an efficiency of 0,016%.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 886–894). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cabai merah (Capsicum annuum L.) merupakan salah satu jenis tanaman hortikultura  penting yang dibudidayakan secara komersial, hal ini disebabkan selain cabai memiliki kandungan gizi yang cukup lengkap juga memiliki nilai ekonomi yang tinggi. Tujuan dari praktek lapanagn ini adalah monitoring penyakit sclerotium pada tanaman cabai merah di Kecamatan Indralaya Utara Kabupaten Ogan Ilir.  Praktek lapangan ini dilaksanakan dengan metode survei dimana penarikan sampel secara laju perkembangan penyakit. Data yang digunakan dalam praktek lapangan ini adalah data primer dan data sekunder. Data primer diperoleh secara langsung melalui wawancara dengan petani, sedangkan data sekunder adalah data-data penunjang dari data primer, yang didapatkan melalui jurnal, buku, arsip-arsip. Berdasarkan hasil praktek lapangan di kecamatan indralya utara kabupaten ogan ilir desa simpang sawit menunjukan pada pengamatan kejadian penyakit sclerotium rolfsii yang diperoleh pada pengamatan penyakit berdasarkan pengamatan  rerata persentase keparahan penyakit layu Sclerotium tinggi pada pengamatan pertama rerata  10 % dan pada pengamatan selanjutnya mengalami penurunan  pada pengamatan kedua 4,1% selanjutnya pada pengamatan ketiga mengalami penurunan lagi ,pengamatan ketiga sebesar 3,5 % berikutnya penurunan kembali pada pengamatan keempat 2,8 % dan rerata persentase keparahan penyakit yang terendah terjadi pada pengamatan kelima sebesar 2,7 %. Pengendalian layu Sclerotium selama ini hanya secara mekanis dengan mencabut dan membuang tanaman yang sakit. Cara pengendalian tersebut kurang efektif karena patogen masih mampu bertahan lama di dalam tanah, dengan membentuk organ pembiakan, yaitu sklerotia.

Abstract

Saputri, R. A., Prayoga, A., Ramadhani, I. S., Pratama, F., & Tamrin, T. (2024). Evaluation of dye sensitized solar cells performance with continuous fiber tissue layer. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 344–357).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the factors that can affect DSSC performance are electrolytes. The addition of continuous fiber tissue can improve DSSC performance by maintaining electron continuity because electrolytes are always available. The fiber tissue used in this study was facial tissue. This research was studied the differences in the width of the continuous fiber tissue layer as an electrolyte provider on the performance of dye sensitized solar cells, especially efficiency and fill factor. This study used several series, namely: preparation of the DSSC structure, arrangement and assembly of the DSSC layer, and measurement of the DSSC. The variations in the width of the continuous fiber tissue layer used in this study were 1 cm, 1,5 cm, and 2 cm. The research parameters observed in this study were: current and voltage measurements, power calculations, Fill Factor measurements, and DSSC efficiency calculations. The results of the study showed that the performance of DSSC with the addition of continuous fiber tissue layers with variations in width had higher performance than DSSC without additional treatment. The best DSSC performance using the addition of continuous fiber tissue was found in experimental unit B with a width of 1,5 cm, namely Isc: 0,0269 mA, Voc: 731 mV, Imax: 0,0103 mA, Vmax: 472 mV, Pmax: 5,0504 µW, FF: 0,257, and an efficiency of 0,01912%.

Abstract

Meranjat Ilir Village is located in the South Indralaya District, Ogan Ilir Regency, South Sumatra Province, with one of the leading products, kemplang. The kemplang business is the main livelihood for the community, as well as an income for craftswomen in Meranjat Ilir Village. One important factor in maintaining product quality, increasing selling value in marketing, and business sustainability is halal certification. The awareness of small and medium entrepreneurs to carry out halal certification is very low. Therefore, an activity is needed to socialize the halal certification process. This community service activity aimed to provide knowledge and understanding, as well as socialize with the community of kemplang crafters in Meranjat Ilir Village regarding the halal certification process for food products, especially kemplang products. The method used was the lecturing method which was carried out through the presentation and explanation of material accompanied by discussion and question-answer. The target audience in this activity was the community of kemplang crafters in Meranjat Ilir Village. The results showed that kemplang crafters in Meranjat Ilir Village gained knowledge and understanding of the halal certification process. There was an increase in understanding of the target audience by 28.39% after the presentation of the material.
