Abstract

Indonesia as a large population country has the potential to become one of the largest consumers of sugar in the world. Indonesia's national sugar needs amounted to 3.2 million tons per year while domestic production was around 2 million tons. In the sugar industry, the benefits of evaporator tools are to thicken clear juice whose dissolved solid number is 7 - 11 oBrix into a thickened syrup with a dissolved solid of 55 - 60 oBrix, this process occurs through the process of evaporation of water content contained in the material. In one sugar factory, the type of evaporator used is a Semi-Kestner Evaporator with the quintuple effect principle. One of the biggest challenges of evaporators is the decrease in heat value of the evaporator due to the onset of mineral crust that inhibits heat transfer. On September 7th, 2021 Q evaporator 1 is at 135874.8 Kw and on October 26th, 2021 Q evaporator 1 is at 121399.2 Kw. Based on the results of data observations on the evaporator carried out in September 2021 and October 2021, it can be concluded that the decreased heat transfer will cause the evaporator's performance in evaporating water from the sap material (clean juice) so that the material flow rate is getting bigger. Efforts that can be made to overcome this are to carry out mechanical cleaning or chemical cleaning per 28 days of the grinding process, to remove crusts on the tube calandria evaporator.

Abstract

The waste problem is never solved. The increase in the amount of waste every day is following the rate of population growth and activities carried out by the community. Tanjung Raja is the oldest district in Ogan Ilir Regency, South Sumatra, Indonesia. One of the educational facilities in Tanjung Raja is SMA Negeri I Tanjung Raja. Related to school environmental problems, especially to reduce the waste that will be brought to the Landfill, SMA Negeri I Tanjung Raja has not done waste sorting. During this time the garbage collected in the place that has been provided according to its designation will be thrown into the Temporary Landfill. Based on the results of observations and interviews with partners, the PKM activities that will be carried out are processing waste generated from school activities. The activity will be done by sorting the resulting waste, then continued by making compost from the leaves produced in school and also other organic waste into compost. PKM devotional activities have produced compost products from organic materials. Partners have come up with solutions to address the waste generated from daily activities and fallen leaves. The compost produced is economically valuable. This activity can overcome the problem of waste in schools and is also useful in preserving the school environment.

Abstract

An eggshell is estimated to have around 10,000–20,000 pores; this condition created a chance for the eggshells to be used as an adsorbent. This research aims to activate egg shells used as an adsorbent. Egg shells were applied as an adsorbent in solutions of lead (Pb) and iron (Fe). Test parameters for adsorption capacity were carried out on the optimum mass and absorption contact time with lead (Pb) and iron (Fe) while using the eggshell waste as an adsorbent. The adsorbent quality of egg shells was tested using parameters such as ash content, water content, and adsorption capacity towards methyl blue. This research aims to utilize egg shells as an adsorbent to absorb lead (Pb) and iron (Fe) content using an adsorption process. There are 3 stages of a method for this research to establish: adsorbent preparation, adsorbent activation, and the adsorption process. The adsorption process was carried out with variations of the mass sample, which are 0.75 grams, 1 gram, 1.25 grams, 1.50 grams, and 2 grams and time variations when contact occurred in 20, 30, 40, 50, and 60 minutes. The outcome of this research showed that the highest adsorption capacity at the optimum mass of Pb metal was 1.5 grams at 98.914% and for Fe metal at 96.386%. The highest adsorption capacity results were influenced by Pb metal contact time in 40 minutes, which was 99.30%, and the best capacity for adsorption of Fe metal was at a contact time in 50 minutes, which was 99.82%.
