Abstract

Every educational institution, both state and private, has the same main task and is important in carrying out lecture activities. These three main tasks are in the form of lecture or academic activities, research activities, and community service activities. These three main activities are commonly referred to as Tridarma Perguruan Tinggi. To carry out these three activities or Tridarma Perguruan Tinggi, health and safety are needed at work. It is known today that all parts of the world have experienced the outbreak of the Coronavirus disease 2019 or Covid-19. This has a very direct impact on the process of implementing Tridarma Perguruan Tinggi. To reduce the spread of the Covid virus outbreak, the actual action is needed that can prevent the transmission of the Covid virus outbreak. The government through the Ministry of Health issued 3M guidelines in preventing and reducing the spread of the Covid virus outbreak. 3M stands for wearing a mask, washing hands, and keeping your distance. However, 3M is not enough, there need to be other actions to prevent and reduce the spread of the Covid virus outbreak in safeguarding all the academics and students of the Cilacap State Polytechnic. One of the other forms of efforts taken in handling the spread of the Covid outbreak in the Cilacap State Polytechnic environment is the manufacture of WHO standard disinfectants and the holding of regular disinfectant spraying.

Abstract

Penanganan limbah saat ini terutama limbah plastik, oli bekas, styrofoam bisa dimanfaatkan menjadi batako ataupun batu bata. Dengan proses sederhana, limbah plastik, oli bekas, styrofoam dapat diubah menjadi produk yang lebih bermanfaat dengan harga bersaing dengan batako biasa. Namun pengujian sifat-sifat fisik batako limbah plastik, oli bekas, styrofoam sebagai bahan bangunan konstruksi masih belum banyak dilakukan. Melalui penelitian ini diharapkan kita dapat mengetahui keunggulan ataupun kelemahan karakteristik batako komposit sebagai bahan bangunan dibandingkan batako biasa.  Tujuan penelitian ini adalah untuk membandingkan karakteristik kuat tekan batako komposit pada beberapa variasi komposisi komposit. Campuran limbah plastik, oli bekas, styrofoam yang dikompositkan dalam batako adalah sebesar 20,26% volume. Campuran oli bekas, plastik, Styrofoam  dan pasir yang dikompositkan dalam batako adalah sebesar 20,26% volume. Cetakan dibuat dari plat baja tebal 3mm dibuat dalam bentuk balok ber alur lebar 150 mm sepanjang 500 mm sebanyak alur 2 buah. Hasil pemeriksaan kuat tekan dibandingkan berat batako oli bekas, plastik, Styrofoam  dan pasir komposisi cetakan III lebih ringan dari cetakan II meskipun voume komposit pada masing-masing cetakan tersebut sama. Hal ini disebabkan karena campuran penekanan pada cetakan II lebih padat daripada campuran pada cetakan III.

Abstract

Dusun Bondan is a district located in a tidal area. Various problems arise in Dusun Bondan because of the use of water that doesn’t meet the quality of sanitation water causing several diseases. The water crisis experienced by the residents of Dusun Bondan becomes the worst disaster especially in summer because the water at Dusun Bondan is salty with high total dissolved solids. A water desalination system has been made to produce sanitation water that meets the standard based on Minister of Health Regulation No. 32 of 2017. The methods used to overcome these problems are water source identification, design of desalination system, purchasing, fabrication and testing of desalinated water. The result of the activities is a desalination system which consists of pre-treatment using 4 filtration stages ended with reverse osmosis desalination using a special membrane. The result of desalinated water test shows that the water is odourless, tasteless, and other parameters meet the requirement of the standard.

Abstract

Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems is the lack of clean water and the PLN electricity network. In 2020, a desalination facility named Sidesi Mas will be built in Bondan Hamlet with a capacity of 240 liters/hour and using the reverse osmosis principle. The energy source for desalination uses a solar power plant (PLTS). Desalination management requires economic analysis, especially in determining the selling price of desalinated water. The cost of producing desalinated water can be calculated using the Cost of energy (CoE) value of the PLTS or the costs incurred to produce electrical energy per 1 kWh. To get the PLTS CoE, this article discusses a simulation to analyze the performance of PLTS desalination systems with Homer software. Homer performs analytical calculations based on a location input, solar energy potential, capacity, and costs of PLTS components as well as electrical load data. The simulation results show that PLTS energy production is 535 kWh/year, the CoE value is IDR 21,975/kWh and the production cost for producing clean water is IDR 183.13/liter.

Abstract

Optimization of volute design is essential for the performance of centrifugal pumps and blowers. This study investigates the effect of volute tongue angle variation on air velocity and flow rate in volute casing design using flow simulations. The volute design was tested with tongue angles of 15°, 30°, 45°, 60°, and 75°, based on theoretical equations of flow rate and volute radius. Simulation results indicated that increasing the volute tongue angle enlarges the volute cross-sectional area. Generally, this enlargement decreases air velocity but increases the flow rate. A 75° tongue angle produced the highest flow rate of 4.860 m³/s, while the highest velocity, 21.35 m/s, was observed at 15°. This behavior aligns with the principle of mass conservation, where a larger cross-sectional area leads to reduced fluid velocity. These findings suggest that volute designs with larger tongue angles can optimize the flow capacity.

Abstract

Modern machining processes heavily rely on liquid coolants to extend the life of cutting tools; however, water-soluble coolants are susceptible to oil contamination, which degrades their quality. This research aims to design the form and details of a disc-type oil skimmer machine, perform the necessary machine element calculations, and test the results. The design process utilizes the VDI 2222 systematic approach with the aid of Autodesk Inventor 2025 software, supported by literature and field studies. The calculation results indicate a required motor power of 0.042 HP, a minimum shaft diameter of 7.2 mm, and a dynamic bearing load of 5.868 N. The frame strength analysis also ensures safety, with a maximum stress of 15.19 N/mm², well below the allowable limit of 79,2 N/mm². In conclusion, this design yields a viable and safe oil skimmer for implementation on the Hurco VM10 series CNC Milling machine, complete with detailed working drawings and an optimal speed of 80 rpm for separating oil from the coolant.

Abstract

This study aims to analyze the effect of orifice thickness on the performance of a porous-orifice microbubble generator (MBG) in aeration processes, particularly concerning the enhancement of dissolved oxygen (DO) concentration and the volumetric oxygen mass transfer coefficient (KLa). The primary issue identified is the limited number of studies that explicitly address the role of orifice thickness as a critical geometric parameter influencing microbubble formation and oxygen transfer efficiency. The research was conducted experimentally under controlled laboratory conditions using two orifice thickness variations, 1.5 mm and 9 mm, with different water and air flow rates, QL and QG. The findings reveal that increasing air flow rate (QG)  correlates positively with higher KLa values for both orifice types; however, the thinner orifice consistently demonstrates superior KLa performance. This behavior is attributed to a steeper pressure gradient and stronger shear forces that promote finer bubble fragmentation and greater gas–liquid interfacial area. Overall, the thin-orifice MBG proved more efficient in enhancing aeration performance compared to the thick-orifice configuration.
