Abstract

Palm Oil Mill Effluent (POME) was high strength organic wastewater contained COD 50.000 – 70.000 mg/l. Mixed cultures used in this research is from cow dung. To increase concentration of bacteria on the inokulum and decreased lag phase on anaerobic treatment for treat it, the anaerobic mixed culture bacteria should be seeding process and acclimatized toward POME. The bioreactor of seeding process and acclimatization using circulating batch reaktor with worked volume 15 L and 5 L, respectively. Ratio wastewater to biomass bacteria was 70:30 (% V/V). This study use 3 variation of heat temperature of mixed culture anaerob that is 35° C for 1 hour; 70° C for 30 minutes; 100o C for 15 minutes with control. The parameter observed in this research was VSS and COD. Seeding process was doing in 5 days with highest VSS on day’s 5 was 8.280 mg/L and COD total concentration was 36.454 mg/L. Acclimatization process was doing on three stages, each of the 5 days. The most increase of VSS at the third stages of acclimatization was found within R1 (heat pretreatment inoculum 35° C for 1 hour) was 880 mg/L/day and the most reduction of soluble COD was found within R3 (heat pretreatment inoculum 100° C for 15 minutes) was 14,30%.

Abstract

Palm Oil Mill Effluent (POME) is highly polluting wastewater with high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in which can caused severe pollution to the environment, typically pollution to water resources. On the other hand, POME was identified as potential source to generate renewable bioenergy through anaerobic digestion. Anaerobic processes need seeding and acclimatization so the microorganism could be adapted. The acclimatization process used circulating batch reactor with worked volume 25 L and glucose and sequential waste ratio of wastewater 50:50 and 0:100 (% V/V). This research observed degradation of soluble COD and growth of VSS. Experiment results showed microbial consortium has been able to adapt to the new environment and degrade organic matter along with increasing waste volume ratio and decreasing glucose volume ratio.Keywords: Acclimatization, circulating batch reactor, Palm Oil Mill Effluent, Chemical Oxygen Demand, Volatile Suspended Solids

Abstract

Palm oil mill effluent (POME) had characteristics to COD, BOD, and protein a sequence of 40.823 mg/L, 15.309 mg/L, 40.500, 58,22 mg/L. pH was influenced the acidogenesis stage in anaerobic process. Additionally, in the stage of acidogenesis H2S was formed compounds, coused odor, inhibit bacterial growth, and corrosion on metal. The control of pH (acid, neutral and alkali) was required in order to optimize the formation of volatile fatty acids and inhibit the formation of H2S. This research is aimed to know the influence of pH and the detention time towards the elimination of H2S and know the influence of pH and the detention time of the formation of volatile acid and H2S. This research was conducted by varying pH the range of 4-4,5 (acid); 7-7,5 (neutral); 8-8.5 (alkali). The result of the research showed the lowest formation of H2S is on acids’ pH with the concentration of formation as much as 0,37 mg/L/hari and the detention time 120 hours. The highest formation of TAV was produced on acids’ pH (4-4,5) with the concentration rate of formation as much as 1.739,45 mg/L, and efficiency elimination 40,05 %. %. It can be concluded pH optimum of inhibhit the formation H2S is pH alkali. While pH optimum the formation TAV is pH acid. Keywords : H2S, total volatile fatty acid, acidogenic, POME

Abstract

Oil palm is a plantation commodity that has a strategic role in Indonesia's economic development. The development of the palm oil industry in Indonesia is inseparable from the role of planting materials used by oil palm plantation farmers. Superior oil palm seedlings are the basic capital to achieve high productivity and quality of palm oil. The use of illegal or careless seedlings can cause a decrease in productivity of up to 50%. In contrast, by using superior quality oil palm seedlings, stable production levels can be guaranteed for 25 years, hence the type and quality of seedlings is a major concern. This community service related to superior seedling selection strategies in order to increase national oil palm productivity was carried out at KUD Kampar. KUD Kampar oversees 20 farmer groups of oil palm farmers in Kampar district, so that through this service it is hoped that the PKM Polytechnic Kampar Team can be a means for oil palm farmers in Kampar Regency to get correct and accurate information about superior oil palm seeds and be able to increase the productivity of the oil palm plantations owned by KUD Kampar farmer groups.

Abstract

In 2023, Riau's oil palm plantation area with cultivation status will reach 3.5 million hectares with palm oil production reaching 9.06 million tons (Ministry of Agriculture, 2023). This figure makes Riau Province the largest palm oil center province in Indonesia. As the area of oil palm plantations increases, palm oil waste will be produced consisting of empty bunches, fronds, shells and fiber. This palm oil waste can pollute the environment in water and soil and can also threaten biodiversity. One use of palm oil waste is compost. Organic fertilizer (compost) is the final and/or intermediate result of changes or decomposition of plant and animal parts and remains, for example cake, guano, bone meal, livestock waste and so on (Ege et al., 2018). The objectives of this PKM are given to students of SMKN 1 Kuok, namely 1) providing early knowledge about the use of palm oil waste, 2) understanding how to make compost from palm oil waste, and 3) socializing the facilities and infrastructure available at Kampar Polytechnic . Large land and facilities for making compost fertilizer are not available in the ATP department of SMKN 1 Kuok. So with this training in making compost fertilizer, we can overcome the problem of places and practicum areas that are not available at SMKN 1 Kuok.

Abstract

Biodiesel, which is generally defined as monoalkyl esters from plant and animal fats, is an alternative fuel that has the potential to be used as a substitute for diesel fuel because of its characteristics. Used cooking oil or used cooking oil haD the potential to be processed into biodiesel and this study aims was to produce waste cooking oil into biodiesel from the results of the pre-treatment process of used cooking oil with bagasse waste, to find out the optimum result of the oil pretreatment proces and the raw material used was used cooking oil from the Rocket Chicken Food Court restaurant. Waste from sugarcane bagasse was useful as an adsorption process for the purification of used cooking oil which was able to reduce free fatty acid levels, water content, and impurities levels for the biodiesel process. The optimum particle size of bagasse waste for used cooking oil pretreatment was 30 mesh, with the analytical data was 1.93% of free fatty acid, 0,0018 % for water content and 0,03% of firt level. The results of the Biodiesel analysis from the pre-treatment process were the viscosity was 5.7 Cst, the density was 860 kg/m3 and the acid number was 0.8 mg KOH/g oil. This result was accordance to the indonesian national standard No. 04-7182-2006.

Abstract

Oil palms have a lifespan of 25 -30 years, so at the end of the period, the oil palm trunks will be rejuvenated. In rejuvenation activities, the waste produced is around 220 m3 /ha. With the large amount of palm oil stem waste produced, it can be used as raw material for making compost fertilizer. The process of making compost fertilizer from palm oil stem waste is adapted to the process of making compost fertilizer in general. In this research, palm stem compost was also made using additional materials such as goat manure and rice bran. Parameters tested include C/N Ratio, C-Organic, NPK, and water content which were tested for 40 days.
