Abstract

Styrofoam is the number 6 plastic in the plastic classification, namely polystyren and styrofoam is categorized as the 5th largest producer of hazardous waste in the world. One method of processing styrofoam waste is biodegradation using mealworm (Tenebrio molitor larvae) because it is able to degrade styrofoam and does not have a negative impact on survival. The research aims to analyze the relationship of pellet from the biodegradation of styrofoam by mealworm to LD50 values with variations in the composition of pellet making. This research was carried out by the experimental method. The results of the biodegradation of styrofoam produce waste are fecula (mealworm feces) and biomass (dead mealworms). Variations in the composition ratio of ingredients in the pellets of each basin are different. Treatment of A = pellets P1 (25% biomass and 75% fecula), B = P2 pellets (50% biomass and 50% fecula), C = P2 pellets (75% biomass and 25% fecula), and D = pellets commercial buoyancy as a control. The results of the LD50 toxicity test on parrot fish, pellet from the biodegradation of styrofoam by mealworm is not toxic.Keywords: styrofoam waste, biodegradation, mealworm, pellet, LD50 toxicity test.

Abstract

The main constraint faced in the utilization of lignocellulosic organic waste is lignin content that is difficult to degrade both enzymatically and chemically. One solution to solve the problem is by composting method with the addition of Trichoderma viride and MOL Tapai. Composting TKKS using windrow method for 40 days. The study was conducted by varying the dosage of Trichoderma viride and MOL Tapai fungi by 50 ml Trichoderma viride, 50 ml MOL Tapai, 25 ml Trichoderma viride + 25 ml MOL Tapai, 35 ml Trichoderma viride + 15 ml MOL Tapai and 15 ml Trichoderma viride + 35 ml MOL Tapai. Measurement of lignocellulose using Chesson-Datta method. The results showed that the pH reached at the end of composting in each reactor was pH 7, the temperature during composting took place at the thermophilic condition with the highest temperature of 660C at R2, R3, and R5, 650C at R1 and R4, water content at the end of composting at each reactor is R1 35,86%, R2 37,67%, R3 37,20%, R4 35,01%, and R5 35,75%, value of C / N ratio at end of composting in each reactor ie R1 14.35, R2 13.22, R3 13.06, R4 14.20, and R5 14.35. The lowest lignocellulose value at the end of each composting was Hemiselulose 13.96% in variation R4 (TKKS + Trichoderma viride (35 ml) + MOL Tapai (15 ml)), Cellulose 14.22% in variation R4 (TKKS + Trichoderma viride (35 ml) + MOL Tapai (15 ml)), and lignin 13.56% in variation R5 (TKKS + Trichoderma viride (15 ml) + MOL Tapai (35 ml)).Keywords : lignocelluloses, Trichoderma viride, MOL Tapai

Abstract

One of the activities that produce CO2eq emissions in campus activities is transportation activities by lecturers, staff, and students. The purpose of this study is to calculate the value of CO2eq emissions resulting from activities at the Faculty of Engineering, University of Riau during the pandemic and during normal conditions, analyze the value of CO2eq emissions resulting from the activities of the Faculty of Engineering, University of Riau during the pandemic and during normal conditions, and provide alternatives to minimize CO2eq emissions resulting from activities at the Faculty of Engineering, University of Riau during normal conditions. Results Total CO2eq emissions from the use of operational vehicle fuel by lecturers, staff, and students during the pandemic were 168,248.58 kgCO2eq/year and under normal conditions 253,135.28 kgCO2eq/year. The chosen alternative to reduce CO2eq emissions is to implement a car free day system once a week in the campus area for students who live 2 km walk to campus supported by shuttle buses and communal parking in front of the campus and propose to students to replace the use of motorized vehicles (cars and motorbikes) by bicycle to campus with a distance of 3 km from their residence.

Abstract

Spent bleaching earth (SBE) is solid waste that is produced from the bleaching industry of palm oil (CPO). In principle, SBE can be regenerated and reused as an adsorbent, but its adsorption capability is limited. This weakness can be overcome through an activation process using one type of mineral acid such as hydrochloric acid (HCl). HCl as a chemical activator can reduce the moisture content in the resulting adsorbent and can dissolve impurities so that more adsorbent pores are formed. This study aims to determine the effect of the effect on HCl concentration and contact time of iodine activation number and SBE surface area. Keywords: Adsorbent, Activation, HCl, Spent Bleaching Earth.

Abstract

The heavy metal found in industrial waste is copper (Cu). The adsorption process of the artificial Cu 2+ solution was investigated using an adsorbent made from Empty Palm Oil Bunches (EFB). EFB is one of the largest solid wastes produced from agricultural activities which contain lignocellulose. Lignocellulose is the main component of EFB which has the ability to adsorb heavy metals because it contains active groups such as –OH and COOH. This study aims to calculate the efficiency of metal ion Cu2+ on EFB adsorbent, with adsorbent mass variation 0.5; 2; 3.5; 5 and 6.5 grams. the best efficiency results were obtained, namely the adsorbent mass of 6.5 grams, which was 79.33%.Keywords: Adsorption, , Cu2+, Palm Empty Fruit Bunches (EFB).

Abstract

Limitations possessed by compos in the form of bulk are in the process of spreading easily carried by the wind and easily drift when carried by the water, and requires a large space during storage, and difficult in the process of distribution. Therefore it is necessary to conduct a study that examines the physical quality of a solid organic fertilizer one of them is by making Granul Organic Fertilizer (POG). This study aims to observe the effect of adhesive concentration on physical quality (POG) produced. The methodology used in this research is variation of 5%, 10%, 15%, and 20% clay adhesive by calculating the value of bulk density, percentage of granule size (2-5 mm), durability value, water absorption value, time dispersion. The best POG quality is on clay adhesive 20%Keywords: Organic fertilizer granules (POG), clay, particle size

Abstract

The empty fruit bunch (EFB) is a solid waste produced in large quantities byindustrial processing of palm oil through 23% of fresh fruit bunches (FFB). EFB is a waste of lignocellulose containing lignin, hemicellulose, and cellulose. The high lignin content in the EFB affects the length of decomposition period. It can be accelerated by adding of white mushrooms, one of paddy straw mushroom (Volvariella volvacea). This research aims to examine the effects of paddy straw mushroom in degrading lignin, C/N, and the effect of adding POME with residual EFB of the mushroom media to the C/N ratio, content of N, P, and K. The method used within two variations of planting mushrooms is precisely by mixingand spreading. The best planting is by implementing the mixed variation with the degradation results of lignin toward EFB of 10.582% and the value of C/N ratio of 38.8. The composting process used in-vessel system and the effect of variation in adding 1 kg of POME, 1.5 kg of POME, and 2 kg of POME to EFB. The greatest value of C/N ratio in adding 2 kg of POME equal to 15.13%. Nitrogen content (N) of 2.64 %, Phosphorus (P) equal to 1.10 %, and Potassium (K) equal to 1.10 % is in accordance with the standard of compost quality of Indonesian Standard National 19-7030-2004.Keywords : Empty fruit bunches, paddy straw mushroom, lignin degradation, POME, invessel system , composting
