Rainwater harvesting is implemented appropriately by striving to use costs that are quite cheap and efficient, but still has many benefits for meeting clean water needs. In this study, the rainwater harvesting model to be analyzed was using the cistern method. The advantage is that it is easier to apply, the amount of water collected is quite large, and it does not require a large area of land. By implementing a culture of harvesting rainwater, can get several benefits, including reducing runoff which can prevent the UTU campus area from inundation and flooding. The average volume of rainwater that can be harvested using a 5-year return period is 110581.12 liter/day with an average volume of water requirements of 7452.09 liters/day. From the results of the rainwater harvesting analysis, it can be concluded that this method is capable of being applied where the analysis results show that the harvested rainwater can meet the water needs of users on the Teuku Umar University campus. In the future, it will be planning where the excess water stored in the cistern will be channeled into infiltration wells to maintain groundwater sources sustainably.

The development of hand sanitizers from a combination of mangrove leaves and patchouli oil has not yet developed in the world and Indonesia, though these two natural ingredients have antibacterial activity as a substitute for alcohol. It is known that many alcohol-based hand sanitizers can cause burning, irritation, dry skin, and cannot be used on wound skin. The purpose of this study was to develop an innovative hand sanitizer in the form of a gel from a combination of mangrove leaves extract and patchouli oil from Aceh. The samples of mangroves (Avicennia) leaves and Patchouli oil were collected from the Kuala Langsa Mangrove Forest and patchouli farmers in South Aceh. Staphylococcous aereus bacteria were obtained from the Laboratory of Universitas Sumatera Utara. This study used a completely randomized design (CRD) with three replications for the gel formulation. The study prepared four formulations namely K (-) as control without mangrove extract and patchouli oil, F-I contained 1g mangrove extract and 10mL patchouli oil, F-II contained 5g mangrove extract and 20mL patchouli oil, and F-III contained 10g mangrove extract and 30mL patchouli oil. Gel hand sanitizer formulations were test for antibacterial active using diffusion method against S. aereus. The data were analyzed using one-way ANOVA. The results of the gel hand sanitizer formulation showed inhibitory effect against S. aereus with the diameter zones of 12.6 mm, 21.33 mm, 19.61 mm and 25 mm for negative control, F-I, F-II, and F-III. The F-III formulation was found as the maximum formula to inhibit the growth of S. aereus.

Samudera Pasai is one of the Islamic Sultanates in Indonesia which appeared in the Middle Ages or around 1267 AD. Evidence of the existence of the Sultanate of Samuedra Pasai in Indonesia is listed in the book Rihlah ilal-Masyriq (Wanderings to the East) written by Abu Abdullah Ibnu Batutha (1304 - 1368 AD), a Muslim adventurer who traveled to Samudera Pasai in 1345 AD. The spatial pattern of the Samudera Pasai Sultanate is no longer visible because there are no traces of archaeological remains in the form of any remaining buildings, except for the tombs of Sultanate figures and historical records of foreign adventurers who have explored the Samudera Pasai Sultanate. This record strengthens the evidence of the existence of the Samudera Pasai Sultanate. The methodology used in this case is a phenomenological approach and a historical approach, which are expected to approach optimal results in uncovering spatial patterns in the development of Islam. The spatial arrangement of the sultanate generally used the concept of catur gatra tungga, which was arranged in the form of: alun-alun (the square) as the center of space, markets to the north of the square, palaces to the south of the square, and mosques to the west of the square. The spatial arrangement then formed a spatial pattern that became the center of the Samudera Pasai Sultanate.

In everyday life, it is not uncommon when we hear the sound of chanting the holy verses of the Al Al Qur’an which are read in mosques before prayer time or in other conditions we seem interested in knowing what Surah and which verse is being recited. This is due to the love of Muslims themselves for the Al Qur’an but not all Muslims memorize the entire contents of the Al Qur’an . Based on the limitations and the magnitude of curiosity about Surah and Verse information, the writer is interested in developing a computer system that can recognize and provide information on the recited Surah and Verse. Advances in computer technology not only make it easier for humans to carry out activities. One of the human intelligences that are planted into computer technology is to recognize the verses of the Al Al Qur’an Surah Al-Falaq through voice. Ada-Boost method is one method to identify or recognize voice classification, and by using this method the success rate in recognizing verse numbers reaches 72%. This system can only recognize the number of verses of the Al Al Qur’an Surah Al-Falaq, recorded sound files with the .wav file extension and built using the Delphi programming language.

Distributed systems increased the performance of a system by allowing applications to be processed in parallel. It helps us to share resources like printers, computers, storage facilities, data, files, web pages, networks, and thus it reduces the cost by shaing a single resource among several users instead of multiple resources. Since multiple machines communicate with each other through the network so they can be easily affected by the attacker and the full system should be corrupted. Users can access remote and local resources but they also may not aware of which machines their processes are running on. So, secure communiction of a distributed system is the most important issue. We need to analyze various vulnerabilities and can take proper protection of the system. In this paper, we discuss different architectural styles of distributed systems. Also, hold up different threads and protection mechanisms to get rid of these threads. The most focusing part of this paper is a summary of various distributed systems security. Here we hold up different distributed system security techniques like SSSE algorithm, BLCS architecture, ODIS algorithm, two eavesdropper model, dynamic cuckoo filter, etc. Finally, we summarize the full discussion like used methodology or architecture, advantages, disadvantages, accuracy, and future work in a table by which an author can easily gather knowledge about the summary of this paper. To better understanding, we show the result of various papers with a visual representation. I think it helps authors to know about security techniques and grow interested to work in this area.
