Abstract

Water is used as one of the primary needs for humans and is also an exemplary process for the human body and other living things, so that clean water is needed when it is consumed. There are various ways to purify water, starting from using natural ingredients to using artificial materials. One method of purification that can be done is by finely grinding the moringa seeds so that the dirt in the water becomes a coagulant. This process is called the coagulation-flocculation method. The purpose of this method is that the purified water has a pH value of around seven and also has a high clarity level value. In order for the data collection process to be accurate, pH and turbidity sensors are needed to measure directly. The pH sensor is used as a measure of acidity and turbidity as a measure of clarity. Based on the results of research and testing tools in the field, the more biocoagulant powder given, namely moringa seeds, can increase the pH value and can reduce the turbidity value in water, with research evidence that in Experiment 1, the pH and turbidity values before purification were 7, 00 and 2940.70 NTU so that when entering Tube 2 and Tube 3 the pH and turbidity values become 7.38 and 2876.30 NTU. In Experiment 2, the pH and turbidity values before purification were 7.0 and 2940.70 NTU so that when entering Tube 2 and Tube 3, the pH and turbidity values were 8.08 and 2789.5 NTU. In Experiment 3, the pH and turbidity values before purification were 7.0 and 2940.70 NTU, and after being purified through Tube 2 and Tube 3, the pH and turbidity values were 8.25 and 2394.63 NTU.

Abstract

Water is one of the basic needs in the life of creatures on this earth. Water is used for the body's metabolism, both humans and other living things. Thus, improving water quality is very necessary because it is very influential for the health of humans and other living things. Therefore, the water filter is designed so that this goal is achieved. Not only, water but environmental health is very important. So, this water filter is designed using solar cell technology, which is one of the ideas of renewable energy, and utilizes moringa seeds (moringa oleifera). This water filter is designed using solar panels and batteries as a source of electrical energy. The panel is coupled and will flow energy from the sun. That energy will be absorbed and received by the battery. This water filter uses a coagulation method and also a natural filter that utilizes fibers, silica sand, zeolite stones, and activated carbon. The process of this filter is to compare the input values detected by the sensor, the pH sensor and the turbidity sensor.

Abstract

Dalam penelitian ini cangkang kulit aren dimanfaatkan sebagai bahan bakar alternatif dengan cara mengubahnya menjadi bioarang sebagai bahan utama pembuatan briket. Tujuan pembuatan bioarang untuk mengetahui kualitas bioarang yang baik dan mengetahui pengaruh variasi waktu terhadap nilai kalor Manfaat pembuatan bioarang selain sumber bahan bakar alternatif,juga digunakan untuk engurangi penimbunan sampah yang menyebabkan pencemaran lingkungan. Pengarangan atau dikenal dengan pirolisis adalah degradasi termal senyawa lignin dengan kondisi tanpa atau hampir tidak ada udara. Pengarangan dilakukan dengan variasi waktu 1,5 jam, 2 jam, 2,5 jam, dan 3 jam. Hasil dari pengarangan yang dinamakan bioarang dianalisa nilai kalornya menggunkan calorimeter bomb. Hasil penelitian menunjukan persentase nilai kalor tertinggi cangkang kulit aren berada pada waktu 2 jam dengan nilai kalor sebesar 5037, 3 cal/gram. Berdasarkan hasil pengujiaan nilai kalor yang diperoleh menunjukkan bahwa bioarang kulit aren (Arenga Pinnata) dapat dimaanfatkan sebagai bahan bakar alternatif yang dapat diperbahuri.

Abstract

Water is an essential source of needs for all living things and human life. For the category that can be consumed, the water must meet several criteria such as chemical, physical, bacteriological and radioactive. From the category of chemical quality, heavy metal is one of the parameters that must meet the standard for the category of clean drinking water, including Fe and Pb. In this study, data were taken three times to simulate the use of this water filter which will be used to analyze the levels of heavy metals Fe and Pb. The results of the first experiment before filtration and the addition of bio coagulants, Fe levels were 0.083 mg/L and Pb levels were 0.0062 mg/L to 0.055 mg/L at Fe levels and 0.0043 mg/L at Pb levels, respectively. The next data is seen in the second simulation, the results of the analysis of Fe levels before the addition of bio coagulants and filtration are 0.087 mg/L and Pb levels are 0.0069 mg/L, but after treatment, Fe levels and Pb levels become 0.063 mg/L and 0.0059 mg/L. Furthermore, in the third analysis, Fe levels before treatment were 0.091 mg/L and after treatment became 0.072 mg/L, while the Pb levels at the beginning before treatment were 0.0084 mg/L to 0.0066 mg/L.
