Abstract

Pada studi ini, telah dilakukkan pembuatan lapisan sel surya silikon amorf terhidrogenasi (a-Si:H) tipe p dengan menggunakan sistem PECVD pada subtrat kaca ITO. Deposisi yang dilakukan selama 30 menit dengan daya RF 3-Watt dan temperatur 2700C. Fabrikasi sel surya amorf menggunakanmetode ekperimen dengan mengalirkan gas silan (SiH4) 20 sccm dengan variasi laju gas Hidrogen (H2) dari 30 sccm sampai 70 sccm dan laju gas Boron (B2H6) 2 sccm dan 4 sccm. Hasil fabrikasi sel surya amorf mendapatkan ketebalan lapisan yang diukur dengan spektrometer (NanoCalc-2000) sebesar 302,8-324,0 nm. Dengan menggunakan pengukuran four-point probe didapatkan konduktivitas gelap 3,34 x 10-3 S/cm dan konduktivitas terang didapatkan 3,91 x 10-3 S/cm. Serta, hasil pengukuran menggunakan UV-VIS mendapatkan energi gap sebesar 1,7-1,8 eV. Fabrikasi lapisan sel surya amorf ini diharapkan dapat meningkatkan efisiensi sel surya berbasis a-Si: H.

Abstract

Slumbung merupakan salah satu desa di Kabupaten Blitar yang sebagian besar masyarakatnya memiliki profesi sebagai peternak sapi, sehingga dari sekian banyak sapi yang dipelihara mengakibatkan penumpukan limbah kotoran sapi. Apabila limbah kotoran sapi tidak ditangani akan berdampak buruk bagi lingkungan sekitar, sehingga diperlukan upaya untuk pengolahan limbah kotoran sapi untuk mencegah pencemaran lingkungan. Kegiatan pengabdian masyarakat bertajuk pemrosesan limbah kotoran ternak sapi menjadi pupuk organik ramah lingkungan di Desa Slumbung, Kecamatan Gandusari, Kabupaten Blitar telah dilaksanakan oleh tim dari Departemen Fisika, Institut Teknologi Sepuluh Nopember. Proses fermentasi selama 2 minggu dilakukan dengan mencampurkan kotoran ternak sapi, EM4 (Effective Microorganism 4), molase (tetes tebu), dan trico G. Dari proses fermentasi didapatkan pupuk organik yang tidak basah dan tidak berbau. Pupuk organik yang telah dihasilkan dapat dimanfaatkan untuk kegiatan pertanian dan dapat dijadikan produk lokal desa yang tentunya sangat berdampak positif pada masyarakat yang tinggal di sekitar lokasi.

Abstract

In an increasingly competitive market, companies are vying to meet customer needs and desires. Consequently, customer satisfaction has become the primary goal of every company. However, PT. EAST JAKARTA INDUSTRIAL PARK is facing a decline in investor shares, indicating that the company's image may need improvement. To this end, this study aims to explore the combined impact of service quality and customer relations on the image of PT. EAST JAKARTA INDUSTRIAL PARK. This implies that these elements of service quality require sustained attention. On the other hand, the tangibles dimension falls under quadrant 2 (focus here), indicating that significant efforts need to be directed towards improving this area as a top priority. PT. EJIP's commitment to fostering strong relationships with its customers is evident in various aspects. These include frequent communication with customers, ensuring product quality, fulfilling agreements with customers, building trust in the company's integrity, reputation, and reliability. Despite competition from other investment vehicles, PT. EJIP strives to retain its customers' loyalty by consistently providing exceptional service and maintaining a reputation as a trustworthy and reliable company. According to the findings of this study, the image of PT. EJIP is jointly impacted by service quality and customer relations. However, a closer analysis reveals that customer relations play a dominant role in shaping the image of the company, while service quality does not have a significant impact. Please refer to Table 4.21 for more details.

Abstract

In oil and gas production, CO2 corrosion and  CaCO3 scale happen simultaneously. Research has been carried out on the corrosion behavior of CO2 on carbon steel samples. Corrosion behavior was analyzed based on changes in temperature (60, 80 and 100 °C) and CaCO3 concentration (0, 700 and 1000 ppm) in seawater environments with CO2 gas at a flow rate of 1 lt/min. The corrosion rate calculation is carried out using the weight loss method. Increasing the concentration of CaCO3 in seawater causes a decrease in the corrosion rate and the greatest corrosion rate occurs at 80 °C. Characterization of corrosion products from deposited powder using XRD and SEM at various temperature changes produces crusts with aragonite, calcite and halite phases. Meanwhile, variations in CaCO3 concentration produce aragonite phases as well as siderite and chukanovite corrosion products with morphologies such as rice grains, rhombohedral, needle-like and plate-likeKeywords: CO2 corrosion, aragonite, siderite and chukanovite

Abstract

This study examines how methane flow rate during the plasma-enhanced chemical vapor deposition (PECVD) process affects the electronic properties of amorphous silicon-carbon (a-SiC) thin films. The films were deposited with varying methane flow rates, and their structural and electronic properties were analyzed using spectroscopic ellipsometry and atomic force microscopy (AFM). Results show that the methane flow rate influences the ratio of sp2 to sp3 carbon bonding, which impacts the material's electronic band structure. Higher methane flow rates increase sp2 carbon content, reducing the bandgap energy and enhancing electrical conductivity. In contrast, lower flow rates lead to higher sp3 bonding, wider band gaps, and decreased conductivity. This study highlights the potential for optimizing methane flow rates in PECVD to tailor the electronic properties of a-SiC films for specific applications. The findings offer valuable insights for designing and optimizing a-SiC materials for electronic devices. Future research will investigate how other deposition parameters and post-deposition treatments affect a-SiC's electronic properties, aiming to further improve material performance for advanced technological applications.
