Abstract

Along with the current developments, electricity has become a basic need that must be required. With population growth, economic development, and an increase in various activities and the use of facilities that require electricity, the use of electrical energy will continue to increase even in the use of lights as lighting in offices. The expected purpose of this study is to examine the efficiency of energy use as office lighting for one of the fertilizer industries before and after using LED lights, as well as analyze the costs incurred and the economic value obtained from the use of LED lamps. In this study, several data are needed, such as building plan data, inventory of the types of lamps used, electrical energy consumption, and the price of electricity consumption per kWh through the calculation method. The difference in costs incurred for the use of non-LED lamps into LED lamps is IDR 580,931.14 in the 1st-floor office building in one of the fertilizer industries and IDR 319,747.56 in the 2nd-floor office building in one of the fertilizer industries. Based on this, the difference in costs incurred is very large, so the use of LED lamps is the main alternative in saving energy and costs. Therefore, it is important to conduct studies and research on the impact that can be caused by the use of LED lights on energy consumption and electricity cost efficiency in the company.

Abstract

The problem of domestic wastewater originating from restaurants is the largest contributor to organic wastewater in urban waters. Among them are waste water parameters, namely oil, and grease. Oils and grease are compounds that do not dissolve easily in water. However, it can be dissolved with non-polar organic solvents. The carbon chains of oils and grease are also long. So, it is difficult to decompose and takes a long time if processing uses the help of microorganisms. So, the alternative is to use physical-chemical processing. In this research, we tried using a static mixer and an impeller mixer. We conducted a systematic review of DAF techniques in wastewater treatment. We reviewed six indexed databases namely dissolved air flotation, microbubbles, wastewater treatment, and key operational and design parameters involved in the effectiveness of the flotation process. In this pre-treatment, the focus is on the withdrawal/discharge speed in collecting wastewater as a test and the effectiveness of mixing wastewater with coagulants and air pressure. These three aspects are used in equilibrium to achieve the optimum dose for the static mixer use scheme. Meanwhile, the impeller mixer scheme uses rotational speed in mixing with the coagulant, contact time, and Reynolds number to achieve the required turbulence. Apart from that, the use of electrical energy in the pump is also calculated in these two schemes. The results obtained were the amount of weight of oil and grease collected in the static mixer pretreatment of 9.12% w/v and the impeller mixer of 7.63% w/v and the results of the organic content of the Chemical Oxygen Demand (COD) parameter for the static mixer were 86.92 % and mixer impeller 78.86 %. From these results, static mixers have advantages over using impeller mixers in terms of the effectiveness of the oil and grease reduction process.

Abstract

Universitas Pembangunan Nasional “Veteran” Jawa Timur is one of the public facilities that produces solid waste, including organic waste, inorganic, and hazardous waste. Waste that can be immediately utilized is organic waste consisting of food waste and leaves and twigs. Therefore, appropriate technology is needed to process organic waste into more useful goods and as a better management alternative through community service. One of the alternatives for processing waste is recycling it into compost using Simultaneous Composting Technology with EM4 and MOL. The main target of this community service is to reduce waste and utilize university waste with appropriate technology for regional coverage and national coverage in the future. The method of this community service is to separate waste between organic and non-organic, selected organic waste is cut by a hammer mill, and then other waste from the canteen activity is made Local Microorganisms (MOLs) as the decaying medium in the composite production of the organic garbage processing device reactor. As a result, this community service has been running smoothly and well. The results of this community service have a positive impact through the use of organic waste into compost which can be utilized by the internal campus and generate economic value.

Abstract

The wastewater from industrial laundries has a high quantity of contaminants from the washing process, as well as chemical additives. The current study assessed the efficacy of the coagulation/occultation/sedimentation (C/F/S) method to treat laundry wastewater in relation to physicochemical parameters of water quality with the goal of treating this type of wastewater. For this purpose, an experimental design was applied to the C/F/S step using the addition of coagulant Alum, coagulant Alum plus flocculant Superfloc, and coagulant HCA. Alum coagulant has removal efficiency of 52% for COD and 37% for phosphate. The use of alum coagulant and Superfloc flocculant produces COD removal efficiency of 60% and phosphate removal efficiency of 58%. The use of HCA coagulant shows a removal efficiency of 64% for COD and 78% for phosphate. This shows that using more HCA coagulant is more effective than using alum coagulant and Superfloc flocculant in laundry wastewater treatment.

Abstract

Universitas Pembangunan Nasional (UPN) "Veteran" Jawa Timur is one of the state universities located in the Rungkut Madya-Gunung Anyar area, Surabaya, where various activities take place daily. Based on the types of activities, the sources of waste at UPN "Veteran" Jawa Timur are divided into two areas: waste from academic buildings, offices, and cafeterias, and waste from gardens and streets. About 70% of the waste generated by campus activities has the potential for recovery. Organic waste from garden sweeping, cafeterias, and other activities can be processed through composting. In addition to composting, there is currently another alternative method with better economic potential, one of which is turning it into eco-enzymes. Commercialization is understood as a process of developing new products from creative industries, making a product more valuable and commercially viable. In this article, commercialization is also understood as a comprehensive technology transfer process, starting from selecting raw materials for a product and continuing through the production process until the product is produced and reaches the end consumer. With the available and applicable processing technologies, it is hoped that this commercialization activity can assist in promoting the transformation of waste into furniture, home décor, and eco-enzymes by business groups. It includes designing commercial packaging for products and creating management and promotion schemes for processed campus waste products at UPN "Veteran" Jawa Timur.

Abstract

This study examines the comparative performance of recycled glass and silica sand as filter media in the slow sand filtration process to treat laundry wastewater. The main objective of this study was to evaluate the efficiency of recycled glass and silica sand in reducing Total Suspended Solids (TSS), turbidity, and phosphate content in laundry wastewater effluent. The selection of recycled glass as a filtration medium is due to its characteristic of having a small sphericity value so that its porosity value is large which results in a small headloss value. The use of recycled glass as an alternative media is an effort to reduce the exploitation of the use of sand media in filtration. The results of the study showed that the use of recycled glass was quite efficient than silica sand in reducing TSS and turbidity with a percentage of TSS removal (94%% vs 90%) and turbidity (90,57% vs 86,04%). While in phosphate removal, silica sand was more efficient than recycled glass with a percentage of removal (46,74% vs 83,48%). Before the research was conducted, a maturation phase was carried out for 2 weeks to form the schmutzdecke layer. The addition of Effective Microorganism 4 (EM4) was carried out to help the growth of the schmutzdecke layer in this study.

Abstract

Cooking oil is an important basic ingredient in the frying process with the main function as a heat conductor, adding savory taste, increasing nutritional value, and heat of foodstuffs. If cooking oil is used many times it becomes less good for consumption, this is because the fatty acids contained will be more saturated and will change color Used cooking oil that has been used is called used cooking oil. Used cooking oil is oil that has been used more than two or three times frying, and is categorized as waste because it can damage the environment and can cause a number of diseases. So the use of used cooking oil is carried out by reprocessing it for the manufacture of solid soap. The participants of this activity were PKK mothers in one of the villages in Gresik, this activity consisted of discussions, demonstrations and direct practice. The results of this service activity show that community members are very enthusiastic about participating in this activity, as can be seen from the many questions they ask and their desire to participate in this activity. The practice and demonstration are intended to provide skills to the participants in determining the right formula in making laundry soap from used cooking oil. Once these activities take place, it is hoped that the development of the talents they have learned in the future will result in financial rewards.

Abstract

Pengelolaan sampah yang efektif dan berkelanjutan memiliki tujuan penting yaitu untuk mengatasi kompleksnya permasalahan sampah, terutama pada sektor pendidikan. Pengelolaan sampah merupakan tantangan yang dihadapi oleh Universitas Pembangunan Nasional "Veteran" Jawa Timur. Sampah di UPN “Veteran” Jawa Timur diklasifikasikan menjadi dua jenis berdasarkan sumbernya, yaitu sampah bersumber dari ruang kelas, kantor dan kantin, serta sampah bersumber dari pekarangan dan jalan. Sangat disayangkan tidak adanya pengelolaan sampah yang baik untuk sampah ruang kelas, kantor, dan kantin. Hanya sebagian kecil yang dikumpulkan dan diolah. Penelitian ini akan menganalisis timbulan dan komposisi sampah di UPN “Veteran” Jawa Timur serta mengembangkan peta sistem pengelolaan sampah untuk memungkinkan metode operasional sampah yang efisien di kampus. Penelitian mengungkapkan bahwa bentuk sampah yang paling umum adalah sisa makanan, dedaunan, kertas, dan botol plastik. Metodologi penelitian yang digunakan menghitung jumlah timbulan sampah berdasarkan peta sebaran yang direncanakan. Limbah makanan, yang mencakup sekitar 51,958 ri total keseluruhan, terutama berasal dari kantin dan asrama. Dampak limbah makanan dipengaruhi oleh faktor-faktor seperti populasi siswa yang besar, ukuran gedung, dan perencanaan makan yang buruk. Berdasarkan hasil penelitian, diusulkan rekomendasi untuk meningkatkan praktik pengelolaan sampah di UPN “Veteran” Jawa Timur. Diantaranya pengadaan wadah sampah dengan warna berbeda untuk memudahkan pemisahan sampah oleh warga kampus. Selain itu, penetapan strategi pengangkutan atau daur ulang sampah juga diperlukan untuk mengoptimalkan operasional pengelolaan sampah di kampus. UPN "Veteran" Jawa Timur bertujuan untuk meningkatkan kesadaran tentang pengelolaan sampah dengan pengadaan tempat sampah stainless steel yang dilengkapi infografis yang menguraikan berbagai jenis sampah. Tujuan dari program ini adalah untuk membantu warga kampus dalam membuang sampah pada sumbernya, sehingga membantu mengurangi produksi sampah.

Abstract

The Snail Canning Industry has the potential to impact the environment if wastewater with high organic compound content is not treated first. This study aims to analyze the performance of the Snail Canning Industry Wastewater Treatment Plant (WWTP) based on BOD, COD, and TSS parameters. The method used is descriptive, with primary data obtained through interviews and secondary data from laboratory test results. Measurements were taken at the inlet and outlet points of the WWTP, then compared with the quality standards based on the Regulation of the Minister of Environment No. 5 of 2014. The results showed that the WWTP succeeded in reducing the concentration of BOD from 201 mg/L to 6 mg/L, COD from 315 mg/L to 24 mg/L, and TSS from 25 mg/L to 6 mg/L. The reduction efficiency of each parameter was 97.01% for BOD, 92.38% for COD, and 76% for TSS. All outlet results met the established quality standards. This indicates that the wastewater treatment process at the IPAL functions effectively in reducing the levels of pollutant parameters in wastewater.
