Abstract

This study aims to analyze the potential for renewable energy development in Lampung Province, Indonesia, using data from NASA POWER and then integrating it with regional geographic and climate characteristics. The analysis focuses on three main types of renewable energy: solar, wind, and hydropower. In solar energy, Pesisir Barat shows significant potential with high and consistent solar radiation levels, averaging 18.61 kWh/m²/day, and stable temperature conditions, making this area suitable for solar photovoltaic (PV) systems. However, Mesuji shows lower solar radiation but remains a candidate for further exploration. Humidity patterns show minimal impact on solar radiation, while stable air pressure improves solar energy prospects in most areas. Based on the analysis, wind energy has limited potential for large-scale projects due to low wind speeds, averaging 1.0–2.5 m/s, but it can be used for micro-scale applications in coastal areas such as the Pesisir Barat and South Lampung. Hydropower presents significant opportunities, particularly in areas with high precipitation and significant topographic variation, such as West Lampung and Tanggamus, which are ideal for large-scale hydropower and micro-hydro systems. Seasonal precipitation patterns and stable air pressure support renewable energy development by providing predictable resource availability.Keywords: Energy, Lampung, NASA POWER. Studi ini bertujuan untuk menganalisis potensi pengembangan energi terbarukan di Provinsi Lampung, Indonesia, dengan menggunakan data dari NASA POWER dan kemudian mengintegrasikannya dengan karakteristik geografis dan iklim regional. Analisis difokuskan pada tiga jenis utama energi terbarukan: tenaga surya, angin, dan tenaga air. Dalam energi surya, Pesisir Barat menunjukkan potensi yang signifikan dengan tingkat radiasi surya yang tinggi dan konsisten, rata-rata 18,61 kWh/m²/hari, dan kondisi suhu yang stabil, menjadikan wilayah ini cocok untuk sistem fotovoltaik surya (PV). Namun, Mesuji menunjukkan radiasi surya yang lebih rendah tetapi tetap menjadi kandidat untuk eksplorasi lebih lanjut. Pola kelembapan menunjukkan dampak minimal pada radiasi surya, sementara tekanan udara yang stabil meningkatkan prospek energi surya di sebagian besar wilayah. Berdasarkan analisis, energi angin memiliki potensi terbatas untuk proyek skala besar karena kecepatan angin yang rendah, rata-rata 1,0–2,5 m/s, tetapi dapat digunakan untuk aplikasi skala mikro di wilayah pesisir seperti Pesisir Barat dan Lampung Selatan. Pembangkit listrik tenaga air menawarkan peluang yang signifikan, terutama di daerah dengan curah hujan tinggi dan variasi topografi yang signifikan, seperti Lampung Barat dan Tanggamus, yang ideal untuk sistem pembangkit listrik tenaga air dan mikrohidro skala besar. Pola curah hujan musiman dan tekanan udara yang stabil mendukung pengembangan energi terbarukan dengan menyediakan ketersediaan sumber daya yang dapat diprediksi.Kata kunci: Energi, Lampung, NASA POWER.

Abstract

The acid hydrolysis method was used to extract nanocellulose from bagasse. This study aims to prepare nanocellulose from sugarcane bagasse by acid hydrolysis method and to know the results of characterization with X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR). In this study, 4 samples were made with variations of H2SO4 of 19, 29, 39 and 45%. XRD analysis shows that with the increase of sulfuric acid, the percentage of each sample increases, but in the 39% sample, there is a decrease in purity because there are still areas of cellulose that have yet to disappear. The phase identification results show that in the sample with 19, 29, and 39% addition, H2SO4 Iα, Iβ, and thenardite phases were formed. In the sample, 45% only form Iα and Iβ phases with a resulting particle size of 2.83 nm and a degree of crystallinity of 55.52%. The results of the SEM test analysis show that the image pattern has stone structures that overlap each other. The results of FTIR analysis show that the functional groups detected are O – H, C – H, C ≡ C, C = C, H – C – H, C – O, and C – O – C, which indicates the presence of nanocellulose.

Abstract

The production of coffee in Indonesia, particularly in Lampung, plays a crucial role in both the local and national coffee sectors. Weather plays a crucial role in the development of coffee trees. Nonetheless, the coffee production is frequently hindered by unpredictable weather conditions. This can be foreseen through the use of scientific forecasting. Blending agriculture and science can maximize coffee production and effective resource utilization. This study creates a predictive model for coffee production by combining machine learning methods with the NASA POWER dataset. Data from NASA POWER is used to acquire information on various weather factors that impact the growth of coffee trees, including solar radiation, temperature, humidity, pressure, soil wetness, and wind speed. Additionally, information on coffee production is sourced from BPS-Statistics Indonesia. The Random Forest algorithm is used to model the connection between variables. The study findings demonstrate that combining machine learning with remote sensing can offer an effective model. Assessment of the R2, RMSE, and MSE figures shows satisfactory results, though not flawless. This happens due to external factors beyond the weather that influence coffee cultivation. The combination of machine learning and remote sensing is incorporated into a website. This model has the potential to be transformed into an app that offers precise details on coffee cultivation in Lampung. This research highlights how remote sensing data can offer insights into predicting sustainable agriculture outcomes.

Abstract

Lucutan corona merupakan salah satu bentuk teknologi plasma dingin yang menjanjikan dalam aplikasi sterilisasi karena kemampuannya menghasilkan radikal oksigen reaktif (ROS) yang efektif dalam menonaktifkan mikroorganisme. Penelitian ini mengkaji karakteristik geometri, konfigurasi elektroda, serta parameter operasi lucutan corona dalam berbagai studi yang telah dipublikasikan. Hasil analisis menunjukkan bahwa konfigurasi pin-to-plate lebih banyak digunakan dibandingkan surface discharge karena kemampuannya menghasilkan medan listrik terfokus dengan intensitas tinggi. Tegangan operasi berkisar antara 10–30 kV dengan frekuensi 0.5–20 kHz, tergantung pada lingkungan bakteri uji. Beberapa jenis bakteri patogen, seperti Pseudomonas aeruginosa, Staphylococcus aureus, Serratia liquefaciens, Salmonella typhimurium, Listeria monocytogene, dan Escherichia coli, terbukti dapat dinonaktifkan secara efektif oleh plasma corona. Namun, tantangan dalam optimasi parameter, efisiensi energi, dan penerapan dalam skala industri masih menjadi hambatan yang perlu diselesaikan. Oleh karena itu, diperlukan penelitian lebih lanjut untuk meningkatkan efektivitas dan efisiensi teknologi ini dalam berbagai aplikasi, termasuk di bidang medis, pangan, dan pengolahan limbah.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi reactive oxygen species (ROS) yang dihasilkan oleh plasma dielectric barrier discharge (DBD) pada konfigurasi rangkaian single dan double menggunakan Optical Emission Spectroscopy (OES). Variasi reaktor DBD digunakan untuk mengevaluasi spektrum emisi plasma. Hasil menunjukkan bahwa intensitas spektrum emisi pada rangkaian double secara umum lebih tinggi dibandingkan dengan Single. Produksi radikal OH dan O pada konfigurasi double lebih stabil, sementara emisi spektrum N₂ menunjukkan intensitas yang lebih besar dibandingkan dengan single. Stabilitas ini diuji lebih lanjut pada sampel dengan pH basa, yang menunjukkan penurunan pH menuju netral. Pengukuran suhu menunjukkan kestabilan selama proses berlangsung, menjadikan konfigurasi double DBD efektif untuk penelitian yang membutuhkan kestabilan suhu larutan. Hasil ini mengindikasikan bahwa rangkaian double dapat meningkatkan efisiensi produksi ROS dalam aplikasi plasma. Kata Kunci: Plasma DBD, spesies oksigen reaktif, spektroskopi optik emisi, rangkaian tunggal dan ganda Abstract This study aims to identify reactive oxygen species (ROS) generated by dielectric barrier discharge (DBD) plasma in single and double configurations using Optical Emission Spectroscopy (OES). Variations in DBD reactors were employed to evaluate the plasma emission spectra. The results showed that the emission intensity in the double configuration was generally higher than in the single configuration. The production of OH and O radicals in the double configuration was more stable, while the N₂ emission spectrum exhibited higher intensity compared to the single configuration. This stability was further tested on a sample with alkaline pH, which showed a decrease in pH toward neutrality. Temperature measurements demonstrated stability throughout the process, making the double DBD configuration effective for studies requiring solution temperature stability. These findings indicate that the double configuration can enhance ROS production efficiency in plasma applications. Keywords: DBD plasma, reactive oxygen species, optical emission spectroscopy, single and double configurations

Abstract

This study aims to characterize the performance of a corona plasma ozone generator, measure the concentration of ozone produced, and analyze and compare the size of ozone microbubbles from two diffusers (C50 and C80) to evaluate the efficiency of ozone mass transfer. The method used was experimental with equipment including a VOSOCO ozone generator, Ozone Monitor, dimmer, high voltage probe, Kyoritsu ampere clamp, SANWA multimeter, flowmeter, aquarium, Apexel 12.5x macro lens, C50 and C80 diffusers, and an iPhone 11, with Python-based microbubble size analysis software for digital image processing. The results showed that the ozone generator operated at 1200 V with a linear relationship between voltage, current, and power, where the highest ozone concentration was achieved at a flow rate of 0.8 l/min. The C80 diffuser produced smaller and more homogeneous bubbles (average 3.37 µm) compared to the C50 (4.09 µm), increasing the specific surface area by 21.4% for better mass transfer efficiency. The innovation of this research lies in the development of a Python-based analysis system with an effective and affordable digital image processing approach to characterize ozone microbubble size, providing an accurate alternative for analyzing critical parameters for optimizing microbubble-based ozonation systems.
