Abstract

Bacteria found in the digestive tract of shrimp mostly play a major role in nutrient absorption. One of the nutritional contents that is quite difficult for shrimp to absorb is fiber. Bacteria that can degrade fiber content are known as cellulolytic bacteria. This study aimed to determine the activity index of cellulolytic bacteria found in the digestive tract of shrimp. The research method includes sampling shrimp with three different categories based on average length and weight, divided into three categories such as large (22.2 g ± 87.3 cm), medium (17.1 g ± 36.7 cm), and small (13.4 g ± 18.8 cm) taken from the north coast waters of Pemalang and the south coast waters of Cilacap. Furthermore, bacterial isolation, morphological observation, calculation of bacterial abundance, and testing of cellulolytic activity were carried out. The results showed that 150 bacteria were successfully isolated from both locations at different sizes and a total of 68 bacterial isolates had cellulolytic activity. There were 22 potential isolates from each coastal water that had a great cellulolytic activity index, ranging from 1.4 to 7.0. Moreover, the most potential activities were performed by 8 bacterial isolates encoded with GM.1, GM.2, GM.3, GM.4, GM.5, GM.6, GM.7, and GM.8 with a range of cellulolytic index obtained ranging from 3.0-7.0. The high activity index of the cellulolytic bacteria obtained is a fairly promising potential as a probiotic candidate that plays a role in degrading fiber in food found in the digestive tract of shrimp so that it can accelerate its growth.

Abstract

Digital transformation in parking systems is essential to improving operational efficiency, staff integrity, and customer satisfaction. PT Reska Multi Usaha (KAI Services) has implemented various technology-based parking systems such as Manless, Full Manless, Combo, and LPR. However, several locations still rely on manual supervision, which increases the risk of fraud and inaccurate overnight vehicle data. This study developed an Internet of Things (IoT)-based prototype system to monitor gate status and manage customer surveys automatically, with real-time data transmission to a centralized dashboard. The system utilizes gate position sensors, microcontrollers, and digital survey forms integrated with an online server. Test results show that the system operates effectively without manual input, with an average data latency of 1.57 seconds and sensor detection accuracy of up to 50 cm. The system has the potential to be integrated with the Early Warning System (EWS) Command Center to support safer and more responsive parking services.

Abstract

Bumi Banjararum Asri Housing Complex is a housing complex located in Banjararum Village, Malang, East Java. This residence has many features to support the comfort of its residents with a location close to educational institutions, health centers and cyberspace centers around Malang, East Java. Apart from that, the main accommodation in Banjararum Asri is very easy to access by cellphone. However, unfortunately, in the current situation, there are many problems, especially in terms of security and public facilities that need attention, including security against motor vehicle theft and the entry of thieves into people's homes at vulnerable hours, including in public places and conditions roads in residential areas that are damaged. Residents do many things to maintain area security, such as putting up warning flags to warn each other of theft, utilizing Internet of Things (IoT) technology to provide security by residents of RT 15/RW XI. They provide security officers and other security (installing gates and adding lights in several areas), but it is not complete because it requires a relatively large budget. The results obtained from the community empowerment activities of RT 15 Housing Banjararum, Singosari in reconditioning security facilities and road facilities in the RT 15/RW .

Abstract

Kreativitas merupakan upaya membangun berbagai kreasi yang memungkinkan bagi pemberdayaan dan penguatan bagi pengembangan bakat yang telah tergali. Dalam kehidupan, kreativitas merupakan hal sangat penting, dengan kreativitas kita akan terdorong untuk mencoba bebagai macam cara dalam melakukan sesuatu. Stimulasi kreativitas pada anak penting dilakukan karena memiliki banyak manfaat positif untuk perkembangan mereka, karena dengan kreativitas, anak belajar untuk berpikir secara kreatif dan melihat masalah dari berbagai sudut pandang. Hal ini membantu anak mengembangkan kemampuan berpikir kritis yang penting dalam menyelesaikan masalah di kehidupan sehari-hari. Salah satu cara mengembangkan kreativitas anak adalah melalui pembuatan karya digital. Karya digital merupakan karya seni atau produk yang dibuat dengan menggunakan teknologi digital atau komputer. Berbeda dengan karya tradisional yang mungkin menggunakan media seperti kanvas, pensil, atau cat air, karya digital melibatkan penggunaan perangkat lunak dan perangkat keras komputer, seperti komputer pribadi, tablet grafis, atau perangkat cerdas. Pengabdian masyarakat yang akan dilaksanakan di MAN 1 Kampus B Kelurahan Pulau Harapan, Kepulauan Seribu diharapkan mampu menstimulasi kreativitas siswa melalui karya digital

Abstract

Design and build a payment system for patient treatment at the Sangrila Clinic at PT Prima Hexa Taslam, South Jakarta. This study uses a descriptive method, which describes and analyzes data based on existing facts and information. The data collection technique used is by conducting field studies which include observations, interviews, and literature studies. Based on the results of the study, it was concluded that Sangrila Clinic still uses a manual system in carrying out the medical record data collection process. This creates several obstacles, namely: employee delays in recording all medical record reports because it is still done manually. The research method used is Library Research and Field Research, the application software used is Microsoft Visual Studio 2010 Ultimate, Microsoft SQL Server Management Studio 2008 R2, Microsoft Word 2019, SAP Crystal Reports, Microsoft Visio 2019, Microsoft Power Point 2019, Google Chrome, and Adobe Photoshop 2015.Keywords: Design, System, Information, Medical Records, Patients.

Abstract

Desa Lebakharjo Kecamatan Ampelgading Kabupaten Malang memiliki kondisi geografis berbukit dengan banyak tikungan tajam yang meningkatkan risiko kecelakaan lalu lintas. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keterampilan dasar pengelasan masyarakat melalui pelatihan Shielded Metal Arc Welding (SMAW). Kegiatan ini juga memfasilitasi pembuatan dan pemasangan tiang cermin jalan pada titik rawan kecelakaan serta membangun dasar pemberdayaan masyarakat melalui keterampilan pengelasan. Metode pelaksanaan meliputi persiapan, pelatihan, pemasangan cermin jalan, serta evaluasi kepuasan. Hasil kegiatan menunjukkan peningkatan pengetahuan peserta dengan N-Gain 0,61 (kategori sedang–tinggi). Penilaian praktik menunjukkan aspek posisi elektroda, kerapian las, dan kepatuhan terhadap K3 berada pada kategori baik hingga sangat baik. Pemasangan cermin jalan dilakukan secara gotong royong pada lokasi rawan kecelakaan. Kegiatan ini terbukti efektif meningkatkan keterampilan teknis masyarakat sekaligus memberikan kontribusi nyata terhadap keselamatan lalu lintas dan peluang pemberdayaan ekonomi melalui pengembangan usaha las komunitas.
