Abstract

Lighting is a major requirement in human life to be able to see objects around clearly, lighting is obtained from natural light sources and artificial light sources. The IDB laboratory building of the FMIPA UNESA has many rooms with different functions and uses, so the lighting of each room must be adjusted to the Indonesian National Standard (SNI 03-6575-2001). Therefore, a program is needed to analyze and determine the number of lights used quickly and accurately in order to achieve safe and comfortable lighting according to (SNI 03-6575-2001). In this case the method used is to use the calculation of the visual basic 6.0 program by inputting the dimensions of each room, namely length, width, height, and the type of artificial lighting used. Based on the results of the calculation of the lighting standards of the IDB building using the visual basic 6.0 program, it is known that only the prayer room on the 1st floor, the microscope room on the 2nd floor, the warehouse on the 1st, 2nd, 3rd and 4th floors and the microteaching room on the 2nd, 3rd and 4th floors meet SNI 03-6575-2001. Whereas for other rooms such as libraries and laboratories cannot meet SNI 03-6575-2001 so that action needs to be taken so that they can meet the standards, namely by increasing the number of lighting points in each room, or it can also be by replacing the type of lighting with a larger lumen value than before.

Abstract

Forecasting demand for screen-printed clothing products at the UMKM "D'mitz Screen Printing" in Sobrah Village, Wungu District, Madiun Regency helps with production control planning to maximize supply chain management for screen-printed clothing products. To predict future product demand, it is very important for UMKM to forecast market demand. Forecasting future demand is very important to avoid sales prediction errors that can cause waste, such as increased production costs due to sales predictions being too large, or stock outs due to sales predictions being too small, which results in customers having to wait longer to get the goods they want. Based on this problem, the UMKM "D'mitz Screen Printing" carried out a demand forecasting analysis for screen printed clothing with the aim of reducing waste and maximizing value. Forecasting demand for screen printed clothing for the next five months using time series analysis and moving average methods. Forecasting results for the period March 2022 to February 2023 show sequential forecasting values of 3266.67; 3300; 3250; 3283.33; 3233.33; 3316.67; 3333.33; 3372.22; 3305.56; and 3272.22. From the Mean Absolute Error (MAE) and Mean Square Error (MSE) calculations that have been carried out, the MAE value is 94.44 and the MSE value is 16018.593.

Abstract

To fulfil the needs of electricity, UNTAG Surabaya Building uses electrical energy derived from PLN. But, the provision of electrical energy from PLN unable to constantly supply electrical energy without interruption. So, to overcome it, it’s obligatory to have an electrical energy back-up system in the form of a Genset so electrical energy for building needs is preserved. The Genset works automatically, so when PLN's electrical energy goes out, the generator will immediately work. Conversely, if PLN's electrical energy back to normal, the generator will stop working. Because the electrical energy back-up system at UNTAG Surabaya has been working for really long, it’s obligatory to evaluate also re-analyze the generator back-up system. The analysis is carried out by performing calculations assisted by the ETAP simulation program. For generator efficiency, it is still quite good, which is only 68.25%., because the generator only supplies loads that are an urgent priority. From the simulation results, the load must be provide by the generator is 273.04kW/341.3kVA and the generator capacity used is 400kW/500kVA. In that case, the performance of the genset is still within the limits of its capabilities.

Abstract

The public demand for better vehicle performance is increasing. Increasing the compression ratio and fuel octane is one solution to improve vehicle performance. This study aims to determine the effect of increasing the compression ratio and ethanol mixture in fuel on the power and torque of the 125 cc Otto engine. The method used is an experiment using a dynotest. The compression ratio was varied to 8.9, 9.2, and 9.6, with ethanol mixtures of 5%, 10%, and 15%. The test data were analyzed using the two-way ANOVA method. The results showed that increasing the compression ratio and ethanol mixture can increase engine power and torque. The highest peak power and torque occurred at a compression ratio of 9.6 with 15% ethanol, which was 6.11 kW and 10.23 N.m. A compression ratio of 9.2 produces 6.07 kW of power and 10.07 N.m of torque at 15% ethanol. A compression ratio of 8.9 produces 5.62 kW of power at 15% ethanol and 9.73 N.m of torque at 10% ethanol.

Abstract

Infrastructure development in urban areas is often faced with various challenges, including ethical issues. The jetty construction project at Pantai Mutiara in Block SB Number 15 A, North Jakarta, is one prominent example in this regard. The jetty, designed to support maritime and tourism activities, has, since its inception, presented a range of issues related to ethical violations. These include manipulation of permits, misuse of funds, disregard for environmental impacts, and exploitation of labour. The ethical violations in this project not only harmed the environment and surrounding communities, but also undermined public trust in the government and related agencies. This case shows how important integrity, transparency and responsibility are in every stage of development. Through this study, we will take an in-depth look at the various aspects of the ethical violations that occurred in the jetty construction project at Pantai Mutiara, including the causes, impacts, and efforts that can be made to prevent similar occurrences in the future. By identifying and understanding the ethical breaches that occurred, it is hoped that valuable lessons can be learnt that can be applied to other development projects in Indonesia. Ultimately, the aim of this paper is to provide constructive recommendations to improve the planning and implementation process of infrastructure projects, so as to achieve a balance between development progress and the ethical principles that must be upheld.

Abstract

Pemanfaatan spektrum gelombang radio telah meningkat pesat dalam beberapa dekade terakhir, namun tidak sejalan dengan ketersediaan frekuensi yang tersedia untuk pengguna. Fenomena ini diperparah oleh banyaknya pita frekuensi yang tidak digunakan oleh pemiliknya, yang menciptakan spectrum holes atau white spaces. Dalam konteks ini, teknologi Cognitive radio (CR) menjadi penting karena memungkinkan pengguna sekunder (secondary user) untuk mengakses dan menggunakan spectrum holes tanpa mengganggu pengguna primer (primary user). CR memungkinkan adaptabilitas perangkat radio dengan memanfaatkan cognitive cycle, dengan tahap utamanya adalah Spectrum sensing, di mana perangkat CR mencari spectrum holes dalam spektrum radio yang tersedia. Tahap berikutnya, Spectrum analysis dan Spectrum Decision, memungkinkan CR untuk mengoptimalkan penggunaan spektrum sesuai dengan kondisi yang ditemui. Paper ini bertujuan untuk melakukan tinjauan singkat terhadap implementasi CR, khususnya pada aspek spectrum sensing. Kami mengevaluasi berbagai teknik spectrum sensing, mengidentifikasi kelebihan, kekurangan, serta tantangan yang dihadapi. Dengan teknologi CR, pemborosan sumber daya spektrum dapat diminimalkan dan efisiensi komunikasi nirkabel dapat ditingkatkan. Paper ini memberikan pemahaman mendalam tentang pengembangan terbaru dalam spectrum sensing pada jaringan radio kognitif, serta memberikan panduan bagi penelitian dan implementasi di masa depan.

Abstract

Breast cancer is a prevalent disease among women that can lead to fatalities. Using deep learning methods to detect and classify tumors can aid in the diagnostic process. Tumors can be classified as either malignant or benign, and doctors require an accurate diagnostic system to distinguish between the two. Even specialists can find it challenging to identify tumors, emphasizing the need for an automated diagnostic system for diagnosing and treating tumors. This study aims to enhance the efficiency of breast cancer diagnosis by implementing a deep convolutional neural network (DCNN). The Wisconsin Diagnostic Breast Cancer (WDBC) dataset was used in the main trials. The CNN technique utilized in this study exhibits superior performance compared to existing methods and achieves a 99.70% accuracy rate in detecting breast cancer.
