Dye-sensitized solar cells (DSSCs) offer advantages such as low production costs, simple fabrication methods, and reduced toxicity compared to silicon-based solar cells, although their efficiency remains a major limitation. The aim of this review is to discuss the fundamental principles of DSSCs and evaluate the electrochemical techniques used to optimize their performance. The method employed is a narrative literature review, allowing the author to synthesize relevant literature from various sources. Current-voltage (I-V) measurements and electrochemical impedance spectroscopy (EIS) are identified as the primary tools for assessing DSSC efficiency and quality. The findings indicate that I-V measurements provide critical metrics such as efficiency and fill factor, while EIS helps identify charge transfer resistance and improves cell stability. Techniques such as voltammetry and Tafel polarization plots offer additional insights into catalytic activity and diffusivity. This review underscores the importance of electrochemical characterization in supporting efficiency improvements and the development of new materials, with EIS playing a key role in modelling cell morphology through equivalent circuit analysis.

Sump Kerinci PT Cipta Kridatama, the jobsite of PT Kuansing Inti Makmur, covers an area with coal reserves at an elevation of 26 meters. However, due to the high intensity of rain, the elevation of the sump increased to 38 meters, hampering mining activities. This study aims to design an efficient dewatering solution through the calculation of planned rainfall, runoff water discharge, and pump requirements, with a specific approach to the design of the open-pit mine drainage system at the research site. The research method involves analyzing historical rainfall data over the past eight years to calculate planned rainfall, rainfall intensity, and runoff water discharge using the Gumbel hydrological method. Pump requirements are calculated based on the technical specifications of the centrifugal pump and the topographical characteristics of the site. From the results of the analysis, it takes 24 pumps to dry the sump in one day, but this approach is not economical. Alternatively, the use of 3 pump units operating for 63 days is proposed as the optimal solution to reduce operational costs and meet the need for dewatering for two months. Sump Kerinci PT Cipta Kridatama, jobsite PT Kuansing Inti Makmur, mencakup area dengan cadangan batubara pada elevasi 26 meter. Namun, akibat intensitas hujan yang tinggi, elevasi sump meningkat hingga 38 meter, menghambat aktivitas tambang. Penelitian ini bertujuan untuk merancang solusi dewatering yang efisien melalui perhitungan curah hujan rencana, debit air limpasan, dan kebutuhan pompa, dengan pendekatan spesifik terhadap desain sistem penyaliran tambang terbuka di lokasi penelitian. Metode penelitian melibatkan analisis data historis curah hujan selama delapan tahun terakhir untuk menghitung curah hujan rencana, intensitas hujan, dan debit air limpasan menggunakan metode hidrologi Gumbel. Kebutuhan pompa dihitung berdasarkan spesifikasi teknis pompa sentrifugal dan karakteristik topografi lokasi. Dari hasil analisis, dibutuhkan 24 unit pompa untuk mengeringkan sump dalam satu hari, namun pendekatan ini tidak ekonomis. Sebagai alternatif, penggunaan 3 unit pompa yang beroperasi selama 63 hari diusulkan sebagai solusi optimal untuk menekan biaya operasional dan memenuhi kebutuhan dewatering selama dua bulan.

The Micro Hydroelectric Power Plant Simulator (MHP) serves as a teaching tool to understand the principles and factors influencing electrical power output. While previous studies have examined the impact of turbine types, elbow angles, and flow rates, limited research has focused on the effect of flywheel diameter. The flywheel diameter influences the torque generated for generator rotation. This study, conducted on the MHP simulator at the Energy Laboratory of Jakarta State Polytechnic, explores the effects of variations in elbow angle, flow rate, and flywheel diameter on electrical power output. Experimental results reveal that these parameters significantly impact power generation. Notably, in case 1, with a 45° elbow angle, a flow rate of 7 L/s, and a 30 cm flywheel diameter, the system produces the highest output of 63 W. These findings underscore the importance of flywheel diameter in optimizing micro-hydropower system efficiency, offering insights for future plant design, especially in water-scarce regions. Simulator Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) digunakan sebagai alat pembelajaran untuk memahami prinsip dan faktor yang mempengaruhi keluaran daya listrik. Meskipun penelitian sebelumnya telah mengkaji pengaruh jenis turbin, sudut siku-siku, dan debit aliran, penelitian tentang pengaruh diameter flywheel masih terbatas. Diameter flywheel mempengaruhi torsi yang dihasilkan untuk memutar generator. Penelitian ini dilakukan pada simulator PLTMH di Laboratorium Energi Politeknik Negeri Jakarta untuk menguji pengaruh variasi sudut siku-siku, debit aliran, dan diameter flywheel terhadap keluaran daya listrik. Hasil eksperimen menunjukkan bahwa ketiga parameter tersebut mempengaruhi secara signifikan pembangkit daya listrik. Pada kasus 1, dengan sudut siku-siku 45°, debit aliran 7 L/s, dan diameter flywheel 30 cm, dihasilkan daya tertinggi sebesar 63 W. Temuan ini menekankan pentingnya diameter flywheel dalam mengoptimalkan efisiensi sistem mikro-hidro, yang dapat menjadi acuan perancangan pembangkit mikro-hidro di daerah dengan sumber daya air terbatas.

Clay soil is known for its low bearing capacity, causing cracking or even collapse in construction. Soil improvement is needed before embanking into building on this type of soil. Methods to increase the bearing capacity of clay soil include compacting the soil or mixing it with additive materials that can improve soil properties. This study aimed to analyze the CBR value of clay soil in the Limau Manis hilly area, Padang City, with the addition of 5% lime and 2%, 4%, 6%, and 8% rice husk ash (RHA). The type of the soil is Organic Silt and Silty Clay (OL). This study conducted physical and mechanical properties of soil testing, i.e. sieve analysis, specific gravity, plastic limit, liquid limit, and CBR value. The results showed that adding 5% lime increased the CBR values of 0-day and 7-day cured soil, both in soaked and unsoaked conditions. The CBR value of the soaked and unsoaked 0-day cured soil sample increased by 189% and 168% respectively, while the CBR value of the soaked and unsoaked 7-day cured soil sample increased by 259% and 215% respectively. However, the addition of rice husk ash decreased the CBR value.

Distance relays in high-voltage transmission systems detect faults by measuring impedance; however, fluctuations caused by power swings can mimic fault patterns and trigger false trips. This paper analyzes the impact of power swings on the performance of distance relays in a 500 kV transmission system using Real-Time Digital Simulator (RTDS) simulations. The results indicate that power swings cause 267 to 299 false trip signals before the actual fault occurs in the observed system. Recommendations include the development of protection algorithms such as Power Swing Blocking (PSB) and artificial intelligence (AI) technologies, including Wavelet Transform, Support Vector Machine (SVM), Chaos Theory, Prony Analysis, as well as hybrid combinations such as Wavelet-Chaos Theory and Adaptive Neuro-Fuzzy Inference System (ANFIS), to detect fault patterns in real-time. Although this study focuses on a 500 kV HVAC system, the findings can be generalized to other nominal voltage systems utilizing HVAC technology. However, further research is required for applications in HVDC-based systems.
