KARAKTERISTIK API HASIL PEMBAKARAN DIFUSI SPRAY BIODIESEL WASTE COOKING OIL AKIBAT PENGARUH TEKANAN BAHAN BAKAR

Minyak jelantah merupakan limbah murah yang melimpah yang dapat dijadikan sebagai bahan pembuatan biodiesel dengan melewati pengolahan terlebih dahulu. Umumnya, minyak jelantah melewati proses esterifikasi dan transesterifikasi untuk menghasilkan asam lemak bebas agar dapat dikatakan sebagai bahan bakar biodiesel. Pada mesin diesel, bahan bakar disemburkan melalui nosel sehingga cairan mengalami atomisasi dan berubah menjadi partikel-partikel kecil (droplet) sebelum mengalami detonasi dan berlanjut pada pelepasan kompresi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tekanan bahan bakar terhadap karakteristik api pembakaran difusi spray biodiesel waste cooking oil dengan hasil yang diharapkan yaitu visualisasi nyala api dan tinggi api. Pada peniltian ini menggunakan minyak jelantah (B100) dan bahan bakar solar (B0) dengan variasi tekanan yakni 3.5 bar, 4 bar, 4.5 bar dan 5 bar. Hasil penelitian didapatkan bahan bakar solar (B0) dengan variasi tekanan 5 bar memiliki nilai tinggi api 129,367 cm yang lebih tinggi jika dibandingankan dengan tekanan bahan bakar yang lainnya maupun minyak jelantah (B100). Hal ini disebabkan oleh nilai viskositas pada bahan bakar biodiesel minyak jelantah (B100) lebih besar, sehingga hal tersebut dapat menghambat deformasi dari bahan bakar yang disemburkan

KARAKTERISASI LAPISAN Ni-Cr BAJA PADA ASME SA 210 C TERHADAP EROSI SUHU TINGGI

Combustion in a high-temperature circulating fluidized bed boiler produces pressurized circulation with silica sand and fly ash particles which can cause damage to pipes due to high-temperature erosional wear. Combustion oxy fuel thermal spray coating method is an alternative to overcome wear and tear. Variations of NiCr alloys were investigated to obtain compositions that could withstand temperatures of 600 °C with a fly ash impact speed of 200 m/s. The main compositions of the metal alloys that have been studied are NiCr, NiCrCo, and NiCrWc. The results of this study indicate that the coating is able to stick to the substrate and survive at 600 °C with a particle impact of 200 m/s in the high temperature erosion test. The highest hardness value obtained by the composition of the NiCr alloy was 177.79 HV and the lowest was found in the composition of the NiCrCo alloy 161.71 HV. The NiCrWc layer is the best layer compared to NiCr and NiCrCo with a weight loss ratio value of -0.00253 gram

Enhanced mechanical and water resistance properties of cassava starch-PVA composites with TiO2 nanofillers for triboelectric nanogenerators films

The utilization of biopolymers for energy applications continues to attract researchers, due to the unique properties of biopolymers that are easily modified, such as cassava starch (CS) biopolymer that has hydroxyl molecular chains. However, the brittle, and non-waterproof nature of starch films is an obstacle to their use in triboelectric nanogenerator (TENG) solid-solid films. This study aims to improve the physicochemical properties of cassava starch films by modifying them into nanocomposite films. The nanocomposite film was made from 70:30 CS/polyvinyl alcohol (PVA) composite and variation of TiO2 nanoparticles addition using solvent casting method. The results showed that the mechanical properties of cassava starch film increased with the addition of PVA. Meanwhile, the addition of TiO2 above 1 wt % of the mechanical properties of the film tends to decrease. The film has low wettability properties with a contact angle of 83.6°. The performance of the nanocomposite film as a Rotary disc freestanding film (RDF-TENG) produces 4.4-fold the output voltage and 2.8-fold the current compared to the film without TiO2. This is a new finding that the CS/PVA-TiO2 nanocomposite film has the potential for TENG films in high-humidity environmental condition

The Vitality of Javanese Language in a Multilingual Society in Solo, Central Java

This study investigates the introduction of javanese vitality in Solo, Central Java, a region celebrated for its linguistic diversity and cultural richness. A significant gap in literature exists in understanding the interplay of sociolinguistic factors such as age, gender, and education on language usage. In this regard, the study intends to assess the current situation with the languages of Solo and the factors that come into play in their preservation and passing on. In this case, the mixed tool included the method of interviewing 40 informants from various populations in order to collect data. Details indicate that domestic languages are mainly used in homes and informal contexts while the Indonesian language was used mostly in formal and public settings. Such developments which are said to be caused by the change of generations, education, and urbanization, highlight the tendency towards the heavy compartmentalization of language usage among generations. Major conclusions report the weakening of the generational shift paradigm and the global tourist trend as one of the stimulating factors for the shift of the language. The focus of the conclusion is on the role of local communities and authorities in implementation of such measures to maintain language diversity and sustain the cultural identity tied to mother tongues. By addressing these challenges, the study contributes to the broader discourse on language preservation in multilingual societies

Implementation of composite paper-based coating for reducing room temperature under galvalume roofing

The increasing amount of paper waste can be enhanced in its utility by transforming it into composites to utilize it as a technology for coating metal roofs to absorb heat. Various paper types have been proven to reduce heat inside the room below when applied to Galvalume roofs. Therefore, multiple types of paper waste are highly suitable for metal roof coatings. This research investigates whether differences in the types of paper mixed with epoxy and applied to the surface of Galvalume roofs will affect the temperature reduction inside the room. These differences in paper types also affect the level of thermal conductivity when measured with the same instruments and dimensions. Data were obtained by mixing small-sized cut paper materials and layering them on Galvalume sheets with the help of epoxy as an adhesive. The temperature data collection process was conducted by preparing 6 boxes with 4 thermocouples supplemented with thermal imaging testing. To broaden the analysis, images of the roof were also taken and analyzed for color to assess the extent of sunlight absorption and reflection on the roof. Four thermocouples were placed 20cm above the roof, above the composite, below the Galvalume, and 40cm below the roof or inside the room. Thermal conductivity data were analyzed separately and integrated with roof color data, further corroborated with temperature data collected by the thermocouples. The four sensors can determine the temperature inside and around the room, focusing on the temperature around the installed composite roof. The analysis shows that adding paper and epoxy-based composites can reduce the thermal conductivity of Galvalume roofs and lower the temperature inside the room below it. Compared to a Galvalume roof without coating, the composite coating with cardboard paper is the most effective, with an estimated average room temperature reduction of 1.9 degrees Celsius. For reducing the air temperature above the roof, the newspaper coating is the best choice, with an estimated average temperature decrease of 2.6 degrees Celsiu
