Abstract

The Clean Water Distribution Pump plays a crucial role in delivering clean water to consumers. Over time, increased noise levels indicate potential damage to pump components, which, if left unaddressed, can lead to severe failures and costly repairs. One of the analyzes of pump damage is vibration analysis. With vibration analysis, damage to the pump in the form of misalignment, mechanical looseness, bent shaft, bearing damage, worn gears, cavitation can be identified. The purpose of this research is to determine the characteristics of vibrations that occur in the pump, so that we can detect damage and failures that occurs and suggest maintenance action. Vibration analysis is carried out using a vibration analyzer to determine the vibration spectrum that occurs in the axial, radial and tangential directions, then analyzing the type of damage and appropriate maintenance to be carried out.  The results showed that this pump indicated: extreme motor free end bearing looseness with a severity score of 99/100, serious motor free end bearing wear with a severity score of 72/100, serious motor drive end bearing looseness with a severity score of 53/100, and moderate motor drive end bearing wear with a severity score of 37/100. and based on the ISO 10816-3 standard, it is recommended that the motor free end bearing be replaced because vibration will cause damage and for the drive end bearing motor it is only recommended to operate for a short time.

Abstract

Pembangunan Gedung Unit Kesehatan Sekolah (UKS) di Sekolah Dasar Negeri 1 Banu-Banua Jaya (BBJ) merupakan bagian dari penguatan infrastruktur pendidikan dasar yang berada di wilayah pesisir dengan akses layanan kesehatan yang terbatas. Dalam konteks ini, perencanaan yang matang diperlukan untuk menghindari keterlambatan dan pembengkakan biaya proyek. Penelitian ini bertujuan untuk merencanakan penjadwalan proyek pembangunan gedung UKS menggunakan metode Critical Path Method (CPM) guna meningkatkan efisiensi dan efektivitas pelaksanaan. Penelitian ini menggunakan pendekatan deskriptif kuantitatif dengan data primer yang diperoleh melalui wawancara dan observasi lapangan, serta data sekunder berupa dokumen Rencana Anggaran Biaya (RAB). Data RAB diolah dengan mengidentifikasi aktivitas proyek, menentukan durasi, dan membentuk jaringan kerja proyek untuk menghitung jalur kritis. Hasil penelitian menunjukkan bahwa jalur kritis proyek terdiri dari aktivitas A-C-B-E-F-I-J-K dengan total durasi pelaksanaan selama 189 hari kalender atau 27 minggu, lebih cepat 25 hari dibandingkan kontrak awal selama 214 hari. Implikasi dari penerapan metode CPM ini menunjukkan bahwa manajemen proyek yang berbasis perencanaan teknis dan visualisasi jaringan kerja mampu membantu pelaksana proyek dalam mengoptimalkan penggunaan waktu dan sumber daya serta mengantisipasi potensi keterlambatan secara lebih sistematis.

Abstract

The Indonesian National Army (TNI) is part of Indonesian society that is trained and educated to maintain the integrity of the Republic of Indonesia. TNI has a life guideline in carrying out its official life, namely Sapta Marga and the Soldier's Oath to improve discipline in the TNI's official life. However, TNI members are only ordinary people, not free from mistakes and actions related to crime. One of them is the crime of desertion during peacetime. The crime of desertion during peacetime is a crime committed by military members by mistake or intentionally being absent without permission for 30 days. This type and research is a qualitative analysis research using primary data in the form of interviews and secondary data in the form of primary legal materials, secondary legal materials and tertiary legal materials. The results of the research are to examine the problems and find answers regarding legal policies, law enforcement and future regulations regarding the crime of desertion during peacetime committed by military members in the regionlaw of TGKH Air Force Base.

Abstract

These blind people still have difficulties in carrying out their activities, especially in terms of mobility in society. This is of course due to the lack of facilities and infrastructure that can support blind people in carrying out their daily activities. One of the assistive devices commonly used is a blind cane. With this stick, blind people are quite helped, especially when walking, but the conventional cane has limitations, one of which is the reach is too short. Thus, in this study, a concept for walking aids for blind people was developed by designing a new device that can cover the limitations of conventional canes. The tool is designed to utilize microcontroller technology with a minimum Arduino uno system, ultrasonic sensor HC-SR04, and DFPlayer Mp3 Mini module. The results showed that the designed tool can detect a maximum distance of 80 cm and can make a sound when the ultrasonic sensor is blocked.

Abstract

In general, sorting waste is still done manually by human hands. For example, it is still done manually by human hands to sort metal and non-metal waste from a pile of garbage. This results in less efficiency in terms of time and energy and also greatly impacts the health of oneself and others. With these conditions, one solution is to build a metal and non-metallic waste sorting system in the trash. The metal and non-metal waste sorting system that is made can sort metal and non-metal waste automatically because it is equipped with an inductive proximity sensor system which functions to detect metal waste plus a NodeMCU module which functions as a data sender of information on the weight capacity of the waste. With this automatic waste sorting system, waste can be sorted according to predetermined types of waste such as metal waste and non-metal waste.

Abstract

The Internet of Things is a development of today's internet-based technology which has a concept to expand the benefits of objects connected to an internet connection continuously. For example, electronic objects, one of which is Arduino. This technology can provide information automatically and in real time. One use of this technological development in the fisheries sector is a pond water monitoring system. In practice, catfish farmers still monitor conventionally, namely by visiting fish ponds. This affects the time efficiency and effectiveness of fish cultivation work. In this research, a tool was developed to help monitor and control the water quality of catfish ponds based on the Internet of Things. The device needed is a temperature sensor. Data from these sensors is recorded by Arduino and then processed into information according to user needs via the internet automatically. Furthermore, this data can be displayed on various platforms, including the mobile web model. The test results show that the development of Internet of Things technology in this system can help farmers monitor water quality automatically. The developed automation system promises to increase success in catfish cultivation.

Abstract

Membaca merupakan keterampilan yang diperlukan sebagai aspek dasar setiap siswa. Namun kemampuan membaca yang kurang pada siswa sekolah dasar khususnya kelas 1 dan 2 belum berkembang dengan baik. Kurangnya kemampuan membaca siswa juga berdampak pada kemampuan menulisnya yang terletak pada (1) cara pengucapan huruf yang runtut dan tidak jelas, (2) pembacaan suku kata, (3) penulisan yang mengandung kesalahan. Penelitian ini bertujuan untuk mengetahui peningkatan literasi membaca dan menulis pada siswa melalui media pembelajaran berupa flashcard Alphabert di SDN Turipinggir 1 Megaluh Jombang. Dari hasil sosialisasi peningkatan kapasitas, rata-rata nilai posttest siswa adalah 54 yang termasuk dalam kriteria “cukup mampu”. Kesimpulan ini menunjukkan bahwa terdapat peningkatan yang terlihat pada diri siswa dari sebelum dilaksanakan tes dan setelah dilakukan tes

Abstract

Tin smelting process produces waste in the form of large amount of slag II. Slag II still consist of major elements such as 0.0619% uranium, 0.530% thorium, 0.179% P2O5 and 6.194% RE total oxide. Based on that fact, the processing of slag II is interesting to be researched, particularly in separating uranium and thorium which contained in slag II. Uranium and thorium dissolved using acid reagent (H2SO4). Percentage recovery of uranium, thorium, phosphate and RE oxides by dissolution method are 98.52%, 83.16%, 97.22%, and 69.62% respectively. Dissolved uranium, thorium, phosphat, and RE were each precipitated. The factors which considerable affect the precipitation process are reagent, pH, temperature, and time. NH4OH is used as precipitation reagent, optimum condition are pH 4. Temperature and time reaction did not influence this reaction. Percentage recovery of this precipitation process at optimum condition are 93.84% uranium and 84.33% thorium.
