Abstract

The presence of water hyacinth in waters can be a threat to aquatic ecosystems. Its naturally fast growth and excess nutrients in the waters cause its growth to become uncontrollable. So it is necessary to handle the biomass and produce it. One thing that can be done is to turn it into organic fertilizer. The problem is, water hyacinth is a lead (Pb) hyperaccumulator plant. So that the biomass produced by water hyacinth contains a large amount of Pb. This study aims to see the effect of vermicomposting on the amount of Pb contained in water hyacinth biomass. The research began by converting water hyacinth biomass into a living medium for earthworms. Changes in Pb levels were observed before and after the earthworms were added. The results found a change with an average initial content of 2.7857 ppm to 2.0477 ppm. So from this study, it was found that the decrease in Pb levels was 26.4924% Keywords: waterhyacinth, hyperaccumulator,biomass, earthworm, vermicomposting.

Abstract

Tongkol jagung telah banyak digunakan sebagai sumber arang aktif atau karbon aktif dengan berbagai cara sintesis karena mengandung selulosa, hemiselulosa, dan lignin dengan kadar yang besar. Arang aktif merupakan senyawa karbon yang daya absorpsinya ditingkatkan melalui proses karbonasi dan aktivasi. Penelitian ini bertujuan untuk mengetahui pengaruh waktu aktivasi terhadap karakterisasi arang aktif tongkol jagung meliputi bulk density, Bagian yang tersisa pada pemanasan 950 oC, dan uji daya serap arang aktif terhadap larutan Iod (I2). Pada penelitian ini digunakan variasi waktu aktivasi 6, 12, 18, 24, dan 36 jam dengan menggunakan H2SO4 sebagai aktivator. Hasil penelitian menunjukkan seiring bertambahnya waktu aktivasi, bulk density semakin berkurang, Bagian tersisa pada pemanasan 950 oC semakin bertambah, dan daya serap terhadap larutan Iod (I2) semakin bertambah, di mana waktu aktivasi yang optimum adalah 36 jam. Data karakterisasi arang aktif tongkol jagung sudah memenuhi SII 0258-88, kecuali pada pengujian daya serap terhadap larutan iod (I2). Kata kunci: tongkol jagung, arang aktif, karakterisasi

Abstract

Papaya plants have considerable potential and have not been widely developed, especially in the seeds because there is a high enough oil and protein content. The objective of this study was to investigate in situ transesterification process which allows direct production of biodiesel from papaya seeds. Changing conditions of the process variables studied were the volume of the methanol (100, 200, 300 mL) and time of process (15,30,45, 60, and 90 minutes) with a specified variables weight and water content of seed, catalyst, stirring speed, temperature and observable effect of the yield of oil extracted to form FAME. Volume of methanol and reaction time significantly affect the yield FAME. The highest FAME yield obtained on the volume of 300 mL methanol and 90 minutes time reaction (77,68%).

Abstract

The development of alternative energy sources is a crucial issue in overcoming energy and environmental challenges in the modern era. One of the efforts to deal with this challenge is to explore the potential for liquid smoke produced from bintaro fruit (Cerbera odollam) waste. This study aims to investigate the process of producing liquid smoke from bintaro fruit seed waste and to analyze the chemical composition of the liquid smoke. The main objective of this research is to assess the potential of liquid smoke from bintaro fruit waste as a sustainable alternative energy source. The research was carried out through a series of laboratory experiments which included the extraction of bintaro fruit seed oil and the conversion of this oil into liquid smoke through a pyrolysis process. The research variable was the temperature of the pyrolysis reactor starting at 300, 400, 500 and 600 oC with 3 kg of treated bintaro fruit raw materials for each variation. The results showed that the highest yield of charcoal product was 1765 grams obtained from a reactor temperature of 400 oC and the production of bio oil tended to increase following the increase in pyrolysis temperature and the highest amount of 190 mL was obtained at a temperature of 600 oC. The results of this study have significant implications for the development of alternative energy sources and organic waste management. In addition, this potential can also provide economic benefits for local communities. Based on the research findings, there is an opportunity for further steps to take advantage of the potential of liquid smoke from bintaro fruit waste as a sustainable and environmentally friendly alternative in meeting future energy needs.

Abstract

Rapid industrial progress and supported by various innovations that are increasingly using lightweight and strong materials, so that sandwich composite research is needed by utilizing existing natural fibers. Composite is an alloy of various materials which is then made using the Hand Lay Up method to create a material that has characteristics that are ductile, light and strong depending on the elements of the carrying material. The sandwich composite with pineapple leaf fiber core and 40% : 60% fiberglass skin which was processed at 70℃ for 8 hours yielded an average maximum stress of 547,721 Kgf. While the pineapple leaf fiber core and fiberglass skin 50% : 50% at a temperature of 80℃ get an average maximum stress of 437,156 Kgf and at a composition of 60% : 40% temperature 90℃ an average maximum stress is obtained of 225,882 Kgf. Furthermore, at the lowest stress the results of the bending test at a temperature of 70℃ the average bending test value is 312,156 Kgf, in the micro tests carried out it can be seen that there are still quite a lot of cavities at high temperatures causing the bending value to decrease, the higher the temperature and the blend of fibers Pineapple leaf that is applied the lower the bending strength value is done, so it can be concluded that the pineapple leaf fiber does not give the maximum effect to the composite material.Keywords: Sandwich Composite, Post-curing, Pineapple Leaf Fiber, Resin, Bending Test, Micro Structure Test.

Abstract

Penelitian ini mengeksplorasi metode pengukuran dan manajemen tekanan air dalam sistem tangki air untuk memenuhi kebutuhan masyarakat dan industri. Tekanan air yang tepat krusial untuk pasokan yang konsisten dan memadai bagi pengguna akhir, sementara ketidakseimbangan dapat merusak pipa dan menciptakan ketidaknyamanan. Fokus penelitian adalah analisis CFD terhadap pipa dan tangki menggunakan Software SolidWorks Flow Simulation. Variasi diameter pipa PVC 1 inci dan ¾ inci dengan tinggi pipa tetap 7 meter menjadi fokus analisis. Hasil menunjukkan tekanan maksimum saat pengisian terjadi pada pipa Output 1 inci dan ¾ inci dengan perbedaan 9 kPa. Kecepatan aliran maksimum terjadi pada pipa Output 1 inci dan ¾ inci dengan perbedaan Penelitian ini dapat disimpulkan bahwa pipa 1 inci lebih efisien dan stabil dalam menjaga tekanan dan kecepatan aliran dibandingkan dengan pipa ¾ inci.
