“…Based on the table, the highest content of CCO is in lauric acid (C12H24O2), myristic (C14H28O2), and caprylic (C8H18O2), which results are in accordance with research [9], [14]. The three fatty acids have short, straight, saturated chains and a small molecular mass so that CCO is more polar, according to the research results from [12], [19].…”

One of the strong candidates for biodiesel is Crude Coconut Oil (CCO) but its high viscosity cannot be applied directly without treatment. Therefore, nanocarbon is added to reduce the viscosity of CCO. Nanocarbon is a natural material with semiconductor properties, a good heat conductor, and can attract other molecules. By adding nanocarbon, it is expected to reduce the viscosity of CCO. This study aimed to determine the combustion characteristics of droplets on CCO by adding nanocarbon by 1% and 5%. The method used was a true experiment with droplets, which dripped on the thermocouple with activation energy from the heater. The results showed that CCO burned 0.933s with a droplet diameter of 4.307mm, droplet diameter of 5.472 mm. By adding 5% nanocarbon to CCO, the CCO burned faster, more reactive, and the ignition was shorter than the pure CCO and 1% CCO.

“…Fullerenes were composed of pure carbon elements totaling 60 (C60), uniquely shaped like a ball, connected by chemical bonds of the type sp3. The vegetable oil used was CCO obtained from the extraction process by dissolving using hexane and then separated using a distillate [12], [19].…”

“…The properties of the eucalyptus oil used in this study is shown in Table 2. CPO has a high viscosity of 48.7 mm 2 /sec as it belongs to the monosaturated fatty group which are predominantly made up of palmitic acid (C16H32O2) as much as 40-47% [13], [14]. It also consists of oleic acid (C18H34O2) by 36-44% [1], with a C18 chain length and a carbon double bond that primarily cause the high viscosity of CPO [15].…”

Article InfoUtilization of crude palm oils (CPO) as biodiesel faces difficulty due to their high level of viscosity. Mixing crude eucalyptus oils (CEO) with CPO may reduce the viscosity due to the presence of aromatic compounds in CEO. The single droplet analysis was performed to determine the characteristics of mixing CPO with the CEO. The results showed that the addition of CEO decreased the viscosity due to the presence of intermolecular attractions, thereby leading to more active molecules in the CPO-CEO mixture. Furthermore, the aromatic compound in the CEO helped in decreasing the CPO flash point, while the aromatic compound in the triglyceride molecule weakens the bonds between molecules. The addition of CEO to CPO tends to reduce the ignition delay due to the presence of cineol content in the CEO, which weakens the van der Waals bond in CPO. AbstrakMinyak sawit (CPO) sebagai bahan bakar biodiesel memiliki viskositas yang tinggi, sehingga perlu penanganan untuk mengurangi viskositasnya. Perpaduan minyak kayu putih (CEO) dengan minyak sawit dapat menurunkan nilai viskositas minyak sawit karena adanya senyawa aromatik di dalam minyak kayu putih. Analisa tetesan (single droplet analysis) telah dilakukan untuk menentukan karakteristik campuran dari minyak sawit dengan minyak kayu putih. Penambahan minyak kayu putih menghasilkan penurunan viskositas karena interaksi antar molekul yang saling tarik-menarik. Interaksi ini menghasilkan pergerakan molekul yang lebih aktif pada campuran minyak sawit -minyak kayu putih. Penambahan minyak kayu putih menurunkan titik nyala bahan bakar. Senyawa aromatik dalam minyak kayu putih menjadi faktor utama yang membantu mengurangi nilai titik nyala pada minyak sawit; senyawa aromatik dalam molekul trigliserida menyebabkan ikatan antar molekul menjadi lemah. Penambahan minyak kayu putih pada minyak sawit menghasilkan pengurangan waktu tunda pengapian karena adanya senyawa Cineol pada minyak kayu putih yang melemahkan ikatan van der Waals dalam minyak sawit. Kata-kata kunci: Minyak kayu putih, Minyak sawit, Biodiesel, Droplet

“…They used parameters such as Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) in their research, with DO indicating water health and BOD serving as a key variable for evaluating river water quality. Higher wind speeds correlated with increased DO concentration and decreased BOD concentration, suggesting improved water quality [21]. Conversely, higher water temperatures were associated with poorer water quality.…”

Yogyakarta faces challenges in maintaining water quality due to the presence of pollutants E.coli as a resulting dominant bacteria. The information provided by the media is easily understood when it is based on the needs of the community. The emergence of various local news media outlets becomes a solution to address the existing issues in society. The local news media in Yogyakarta has not yet made a significant impact on the environment, particularly in water resource management, as evidenced by the numerous complaints from the community regarding water quality. Primary data of this research is gained through qualitative content analysis and in-depth interviews with journalists of local news media outlets in Yogyakarta, namely harianjogja.com, krjogja.com, and tribunjogja.com, and twelve journal articles in the period from 2019 to 2023. The findings are Harian Jogja, Tribun Jogja, and Kedaulatan Rakyat, demonstrate insufficient resonance in their coverage of water source pollution management. This is evident through several factors: limited frequency of news coverage, absence of dedicated desks within the editorial teams, lack of specific sections dedicated to environmental topics, low traffic generated by related news articles, and a lack of specific attention from editors regarding water pollution management in terms of assignment and environmental education for journalists. The majority of news articles written by journalists in this context predominantly fall into the informative category, accounting for 71% of the coverage. In contrast, articles categorized as educational or solution-oriented are minimal. The findings of this research endeavor aim to contribute academically to the field of water pollution management by emphasizing the need to optimize the utilization of local news media in Yogyakarta.
