Abstract

PT. XYZ is a company that produces motorcycle and car tires. This company has a fairly broad product market, so the products it manufactures have good product quality. In producing tires, one of the machines used in producing tires is an extrusion press machine. In carrying out its production, the extrusion press experiences downtime in the period August-December 2022, where the biggest downtime occurs in August, which has a downtime of 1890 minutes. After conducting an analysis using the Overall Equipment Effectiveness method to determine the level of effectiveness of the extrusion press machine, the OEE value calculation results from the August-December 2022 range are less than the international standard value of 85%. so we need an increase in the OEE value on the extrusion press machine. In increasing the OEE value, better engine maintenance is needed, so the Total Productive Maintenance (TPM) method is used as an effort to make engine maintenance even more effective.

Abstract

The problem that often occurs in people who use semi-jet water pumps is that when the installation of the water pump has been completed, it turns out that the water discharge cannot flow as expected and the electricity consumption is quite large. This research is expected to get optimal results, when installing the water pump installation, it is expected to get the largest water discharge by varying the valve location with the in-late angle, so that it will reduce the time to use the water pump. The experimental results with the linear regression method show that optimal conditions are achieved at variation 8 meaning to maximize the water discharge at the semi-jet water pump, namely the location of the valve above with an in-late angle of 450. The results of the comparison between the average value of water discharge for general use conditions are 29 .6 liters/minute with an average value of water discharge under optimal conditions of 34.8 liters/minute, indicating that the value of water discharge under optimal conditions can increase the water discharge by 5.2 liters/minute = (34.8 liters/minute – 29 ,6 liter/minute), so there is an increase of 8.0745 % = { [5,2 / (34,8+29,6)] x 100%}.

Abstract

The increase of biodiesel production capacity is followed by an increase in crude glycerol production as a by-product. Crude glycerol still has a low purity and a lot of impurities so it requires special treatment so that it can be utilized and valuable. One of the ways to increase the purity of crude glycerol is in the adsorption process. This study aims to determine the best conditions for the adsorption process and the characteristics of the glycerol produced after the adsorption process. The initial condition of crude glycerol purity is low, namely 67.8%, so purification is needed. One way of purifying crude glycerol is by physically separating it using fly ash as an adsorbent. The experiment was carried out with the adsorption process using fly ash with the adsorbent mass variable 30,35,40,45, and 50 grams and the adsorption time variable was 50,60, and 70 minutes. The purified products are analyzed quantitatively and qualitatively, including glycerol content, density, viscosity, moisture content, ash, and MONG. The best conditions for the adsorption process using fly ash were obtained at a mass of 50 grams with a time of 50 minutes with the results that the glycerol content was 97.5%, water content 0.03%, ash content 0.0432%, MONG content 2.426%, density 1.253 gr / ml , viscosity 233.56 cP. Based on these results, purified glycerol was obtained that met the quality standards of SNI 06-1564-1995.

Abstract

The use of Personal Protective Equipment (PPE) can protect against exposure to the COVID-19 virus, but on the other hand it causes an increase in the generation of plastic waste. The amount of COVID-19 PPE waste is estimated at 1.6 million tons per day with masks or face shields worth 3.4 billion per day. The urgency of handling PPE waste is not only due to the volume of waste, but also the nature of the virus that survives on solid surfaces. This publication aims to provide a systematic review of PPE waste management in Indonesia, both from health facilities and households. Good practices from abroad are explored to see the potential for developing PPE waste management in Indonesia. The search results provide 38 articles, namely 21 national articles and 17 international articles. PPE waste management in Indonesia and abroad in general is separation, disinfection, collection/temporary storage, transportation, and final disposal (incineration/sterilization/landfill). 3R practice improvement (reuse, reduce, recycle) can create sustainable PPE waste management, for example, the use of environmentally friendly materials, reuse PPE after sterilization to increase lifetime or conversion of PPE waste into raw materials.

Abstract

Material komposit yang diperkuat dengan serat merupakan material rekayasa teknik yang saat ini banyak digunakan karena memiliki kekuatan dan kekakuan spesifik yang lebih baik daripada material teknik. Serat alam merupakan pilihan alternatif sebagai penguat komposit karena serat alam merupakan material komposit yang ramah lingkungan dan bisa didaur ulang. Selain memiliki nilai ekonomis yang tinggi, limbah ampas tebu sangat mudah didapat, murah, tidak membahayakan kesehatan, dan dapat terdegradasi secara alami (biodegradability) sehingga nantinya dapat dimanfaatkan sebagai serat penguat komposit mampu mengatasi permasalahan lingkungan. Tujuan penelitian ini adalah untuk mengetahui pengaruh (komposisi/persentase/kandungan) serat ampas tebu terhadap penyerapan suara panel akustik. Panel akustik dibuat dengan mencampurkan serat ampas tebu, semen, dan air. Variasi (komposisi/ persentase/kandungan) serat ampas tebu dimulai dari 2% sampai 10%. Untuk uji karakteristik penyerapan suara dilakukan dengan menggunakan metode ruang dengung berdasarkan ISO-354 (1985), dengan sumber suara white noise. Hasil penelitian menunjukkan bahwa semakin tinggi komposisi serat ampas tebu, semakin tinggi pula nilai koefisien penyerapan suara dari panel tersebut. Serapan suara terbaik dengan nilai koefisien penyerapan 0,4 terjadi pada panel dengan persentase serat ampas tebu 10%, menggunakan sumber suara  white noise.

Abstract

Mining activity is one of the producers of coarse particulates and fine particulates in the air which can have an impact on the surrounding environment. Limestone mining carried out by PT. Semen Padang is likely to contribute particulates such as Total Suspended Particulate (TSP) in the air. This study evaluates the dispersion pattern of TSP with variations in time and place to see its movement and direction of spread to determine affected areas or areas with high pollutants. Sampling and location determination refers to SNI 19-7119.6-2005 which consists of 30 observation points in 8 cardinal directions in the area around mining. Meteorological data was taken to see the dominant wind direction using the PCE-FWS 2.0 tool and then processed using the WR Plot software. TSP concentrations were measured using an EPAM 5000 tool which was divided into 4 shifts with the duration of each shift measured for 30 minutes, then TSP concentrations were mapped using Surfer 10 software. The results showed that TSP concentrations in the morning and afternoon were influenced by sampling distance and mining activity. , while the concentration of TSP at night is influenced by the wind direction and the sampling location. The TSP dispersion pattern in the morning and afternoon tends to be east, south, and west, while at night the dispersion pattern tends to be high in the southwest direction.

Abstract

Kegiatan penangkapan nyamuk dalam survei dan pembelajaran praktik di laboratorium selalu menggunakan aspirator. Aspirator adalah alat yang digunakan untuk menangkap serangga yang sangat kecil, lembut, gesit, dan aktif yang sulit dikumpulkan dengan pinset atau sikat, seperti nyamuk. Aspirator yang banyak digunakan untuk menangkap nyamuk saat survei maupun di laboratorium sederhana yaitu aspirator mouth suction. Penggunaan oral suction aspirator rentan terhadap penyebaran kasus COVID-19 karena selain dihisap melalui mulut, juga digunakan secara bergantian. Sehingga perlu dikembangkan berbagai model aspirator otomatis tanpa penyedot mulut. Metode penelitian yang digunakan adalah Research and Development (RD). Berdasarkan uji daya hisap, model kipas memiliki kecepatan hisap maksimum 5cm sedangkan model katup 1 cm. Model aspirator kipas menerima 3,82 atau sangat baik dibandingkan dengan model katup 3,4 atau baik.
