<![CDATA[In order to develop and expand business expansion, the photocopy business owner plans to open a new business branch by renting a shophouse. The choice of location requires careful consideration of several factors because it will affect revenue and business strategy to get maximum profit and have an impact on business continuity. The purpose of this study is to analyze the decision to choose the location of the photocopy business branch with four alternative locations. Location selection was carried out using the Cut Off Point method to determine important criteria to consider, Analytical Hierarchy Process (AHP) was used to weight the selected criteria and Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) as a complement in determining the location selection. The results with a Cut Off Point from five competent business experts, selected 8 criteria from 20 criteria such as rental prices, proximity to consumers, and market opportunities. Weighting criteria with AHP obtained three criteria with the highest weight, namely the price of renting a place, market opportunities, and cleanliness of the place. TOPSIS calculation results obtained preference values of 0.704 (Cipayung), 0.647 (Cakung), 0.477 (Cimanggis), and 0.297 (Ciputat). So, the shophouse in Cipayung was chosen as the best alternative.]]>

<![CDATA[Having published three articles in the Journal La Multiapp: “Doppler Effect and Acoustic Trails of Neutrinos”, “Neutrinos above the Earth's surface” and “Algorithm for detecting acoustic traces of neutrino decay”, I already wanted to stop research in this direction, if only because that I do not have enough competencies in astrophysics, and that published data is enough for specialized specialists to evaluate the technical and scientific novelty and understand the capabilities of the new method. But, when on the morning of February 3, 2024 at 07:40:19 I turned on the monitoring system, bipolar acoustic pulses with a visible period of 40 μs (frequency 25 kHz) began to be observed on the screen with an interval of about 0.3 seconds, the shape of which is very similar to acoustic traces, associated with neutrino decay. The apparent frequency of these pulses was underestimated by a factor of two, probably due to the insufficiently high Nyquist frequency (50 kHz). A similar picture was observed during the next registration at 07:40:38, and at 07:40:57, only five pulses were recorded with a repetition interval of 1 second. On the fourth and fifth of February there were practically no impulses. There was a suspicion that the observed process was timed to coincide with a geomagnetic storm; more precisely, it was the observed processes that caused geomagnetic storms.]]>

<![CDATA[CV. XYZ found barriers that could hinder the implementation of a sustainable supply chain in the company. However, the company does not have a resolution method for determining the priority barriers that most influence the implementation. The aim of this research is to determine the barriers that influence the implementation of a sustainable supply chain. Settlement is carried out using the DEMATEL-ISM method. The research results show that the most influential barriers are lack of regulation and guidance from the government (A9) and high initial investment (A1). Because in the DEMATEL-ISM integration, these two factors were found to be located at the lowest level, which is the level with the most influential barriers, which are the main drivers. As a result, companies need to prioritize lack of regulation and guidance from the government and high initial investment as a basis for evaluation and improvement in implementing sustainable supply chains.]]>
