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
Hadir nya aplikasi online shop adalah salah satu dampak dari globalisasi. Aplikasi online shop ini memudahkan banyak orang untuk berbelanja, terutama para remaja. Tak terkecuali mahasiswa Sosiologi angkatan 2021 Universitas Negeri Malang. Maka dari itu kami mengambil judul penelitian Gaya Hidup Konsumtif sebagai Dampak Hadirnya Online Shop di
The presence of an online shop application is one of the impacts of globalization. This online shop application makes it easy for many people to shop, especially teenagers. No exception for Sociology students batch 2021, State University of Malang. The purpose of this study was to find out changes in student lifestyles as a result of the online shop among students majoring in Sociology batch 2021, State University of Malang. This study uses descriptive qualitative methods with open interview data collection techniques and literature study. After interviewing several students, it can be concluded that online shopping is very popular because it is easy and has many choices. Besides that, online shopping can also save time. However, this shopping habit has a negative impact among students, namely a consumptive lifestyle that is difficult to avoid. The emergence of a consumptive lifestyle as a result of the existence of an online shop is in line with Jean Baudrillard's theory of consumption society, where current consumption is not based on need but based on desire.
Pada penelitian ini telah dilakukan sintesis antara serbuk partikel nano TiO2 dan serbuk partikel nano ZnO menjadi pasta yang akan diaplikasikan sebagai elektroda pada dye-sensitized solar cell (DSSC). Elektroda pada DSSC ini bekerja berdasarkan adsorbsi foton oleh pewarna, elektron yang tereksitasi ditransfer ke TiO2/ZnO yang mempunyai perbandingan berbeda. Dimensi material partikel nano TiO2/ZnO sebagai elektroda sangat penting untuk menghasilkan efisiensi yang lebih tinggi pada DSSC. Sifat ini sangat dipengaruh oleh metoda pabrikasi elektroda TiO2/ZnO dan parameternya. Pada penelitian ini digunakan metoda doctor blade untuk pabrikasi DSSC dan larutan dyes (Z907) sebagai zat pewarna. Tujuan penelitian ini adalah untuk mengetahui pengaruh pencampuran serbuk TiO2 dan serbuk ZnO sebagai elektroda. Teknik pembuatan pasta TiO2/ZnO sebagai elektroda sangat penting untuk menghasilkan efisiensi tinggi pada DSSC. Teknik ini sangat terkait dengan material TiO2/ZnO, metoda pabrikasi, dan parameter pengukurannya. Dalam penelitian ini dibahas hasil karakterisasi XRD pada kedua serbuk TiO2 dan ZnO, hasil SEM pada pencampuran kedua material, hasil pengujian IPCE serta hasil pengukuran effisiensi pada pengujian I - V.
