Dye-sensitized solar cells (DSSC) are widely developed due to their attractive appearance and simple fabrication processes. One of the challenges that arise in the DSSC fabrication involves high material cost associated with the cost of conductive substrate. DSSC with monolithic configuration was then developed on the basis of this motivation. In this contribution, titanium dioxide-based monolithic type DSSCs were fabricated on a single fluorine-doped transparent oxide coated glass using porous ZrO2 as spacer. Herein, the catalytic material for the counter-electrode was varied using carbon composite and platinum in order to analyze their effect on the solar cell efficiency. Four-point probe measurement revealed that the carbon composite exhibited slightly higher conductivity with a sheet resistance of 9.8 Ω/sq and 10.9 Ω/sq for carbon and platinum, respectively. Likewise, the photoconversion efficiency of the monolithic cells with carbon counter-electrode almost doubled the efficiency of the cells with platinum counter-electrode. Our results demonstrate that carbon could outperform the performance of platinum as catalytic material in monolithic DSSC.
Oil palm is one of the largest agricultural products in Indonesia and has high economic value and can improve the welfare of oil palm farmers. The research was conducted at PT. Agro Putra Lestari regarding palm oil production, having its address at Jln.Imam Bonjol No.179 Kisaran with the name of the leader being Mr. Anda Puta Lubis, SE, M, Ma. PT. Agro Putra Lestari is a company that produces palm fruit products which is still running. PT. Agro Putra Lestari spread across the Asahan area, including Meranti, Simondol 1, Simondol 2, Simondol 3, Lahan Camat, Sitampu Saring, Marpaung, Miri-Miri, Solo Baru, and Lahan Kembar. The problem that often occurs is the amount of oil palm fruit production which is fluctuating so that the company does not know the estimated production of oil palm fruit in the following month. PT. Agro Putra Lestari has difficulty in knowing the results of oil palm fruit production in the following month because of improper planning to predict the production and have not applied the comparison of the weighted moving average and double exponential smoothing methods in predicting the amount of oil palm fruit production at PT. Agro Putra Lestari. The data used is from June 2021 to May 2022. The results of the forecasting of the two methods are compared to find out which forecasting results have the smallest error value, where the smallest error value can be used as a reference for future oil palm fruit production.

AbstrakTujuan PKMM ini adalah memberikan pelatihan pengolahan tanaman singkong menjadi aneka makanan olahan yang bernilai ekonomi tinggi. Target kegiatan PKMM ini adalah memberikan pelatihan kepada ibu rumah tangga di Dusun Mrico Desa Lebak, Grobogan. Setelah diberikan pelatihan maka selanjutnya mereka akan melakukan praktek secara terbimbing dan dilakukan pendampingan usaha. Pelatihan dilakukan secara berkelompok dengan pendekatan andragogi. Materi pelatihan disajikan dengan lebih banyak praktek dari teori, dengan rasio perbandingan 30 % teori dan 70 % praktek. Pelaksanaan PKMM telah memberikan pengetahuan kepada peserta pelatihan tentang diversifikasi olahan singkong, pengemasan dan pelabelan, sertifikasi cara produksi pangan yang baik, tata letak produksi, kewirausahaan, perhitungan harga jual dan titik impas, serta materi praktek pengembangan produk yang meliputi pembuatan keripik singkong aneka rasa. Pengabdian berjalan dengan baik karena adanya koordinasi yang baik antara ketua tim PKMM dengan anggota tim PKMM dan juga komunikasi yang baik dengan pihak eksternal mitra untuk menjalin kerja sama yang berkelanjutan. Namun demikian, masih ada satu kendala yaitu mindset warga yang masih sulit berubah menjadi wirausaha. Oleh karena, untuk merubah mindset tersebut tim
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
