Abstract

This study was conducted to examine the utilization of solid waste oil palm and SP-36 on the growth and yield of cayenne pepper on spodosols. This experiment used a factorial Completely Randomized Design (CRD) consisting of 2 treatment factors and 3 replication. The first factor is the provision of solid palm oil consisting of 4 (four) levels, namely without the provision of solid palm oil, 10 ton.ha-1, 20 ton ha-1, and 30 ton ha-1 solid palm oil. The second factor is the administration of SP-36 consisting of 4 (four) levels, namely : without giving SP-36, 100 kg ha-1, 200 kg ha-1 and 300 kg ha-1 SP-36. The variables observed were plant height, number of flowers plant-1, shoot/root ratio, dry weight plant-1, and fresh weight of fruit plant-1. The results showed that there was an interaction effect between oil palm solids and SP-36 on plant height, number of flowers, and fresh fruit weight of plant-1 on spodosol soil. The combination of solid oil palm 20 tons ha-1 and SP-36 200 kg ha-1 was the best combination in increasing the growth and yield of cayenne pepper on spodosols and produced the heaviest fresh fruit weight plant-1, which was 68,33 g plant-1.

Abstract

Wastewater originating from household, industrial, and public places that contains materials can endanger human life and living things and disrupt environmental sustainability. Various methods have recycled domestic wastewater. One is through the photodegradation process utilizing ultraviolet light in the photocatalytic process. Inorganic materials are semiconductors with photocatalyst activity that can absorb photons and simultaneously carry out material interface transformation reactions. The research aimed to determine the effect of adding Fe metal dopants on TiO2 photocatalyst activity in simulated methylene blue and domestic waste treatment. The precursor used was TiO2 P25 Degussa Anatase. Fe dopant was added using the hydrothermal method with variations of 2%, 4%, and 6%. The XRD characterization results show that TiO2 has a high degree of crystallinity, so the overall process of electron diffusion and electron transfer in SSPT is higher to increase its efficiency. SEM-EDX characterization results show that TiO2-Fe particles are scattered in a spherical shape with a size of less than (<)100 nm and tend to agglomerate. Test results of simulated methylene blue (MB) waste with a UV-Vis spectrophotometer at variations in mass, concentration, pH, and time showed that the addition of doping could increase photocatalytic activity and optimum conditions at 6% (F6) were used in the analysis of parameters pH, COD and TSS of domestic wastewater. The pH value increased from 5 to 6, % COD degradation was 59.17%, and TSS was 23.07%. This research showed that TiO2-Fe was effective enough for domestic wastewater treatment.

Abstract

The goal of education is to actively develop students' potential by establishing a learning environment and process. Most students still find learning chemistry in high school or trade school to be challenging. One way for universities to help schools grow and enhance secondary school students' skills is through the Assisted School Program. Students in this program receive training to help them develop a broad perspective, expose them to the working world, and encourage their innovative spirit. Students at the target school responded favorably to this exercise, as evidenced by the average proportion of their responses on the indicators of interest, responsiveness, and satisfaction that met positive criteria. Students at this aided school, SMK Negeri 2 Pekanbaru, responded actively to the activities 94% of the time, whereas SMK Negeri 1 Tualang received the fewest replies (72%). In general, student responses regarding their level of enthusiasm in the targeted school activities are excellent. Overall, the guided inquiry method's student replies were rated as good. This is demonstrated by the percentage of each statement falling into the very good category, the overall student response rate of 81.88%, and the pre-test and post-test results, which showed that it had an impact on students' knowledge growth as indicated by the higher post-test scores compared to the pre-test score.

Abstract

Increased production in industries tends to increase burden and complexity of waste produced. For this reason, it was necessary to develop materials that have good degradation capabilities and into environmental products. In this research, the MnO2 has been synthesized using the strategy of coprecipitation and reducing agents. The as-synthesized MnO2 is then used for the degradation of methylene blue. The results of this study indicate that different strategy of coprecipitation and reducing agents produce different MnO2 and has unique properties as nano-hierarchical microstructure. Using citric acid as a reducing agent results in a hierarchical structure of α-MnO2 and Mn2O3, while oxalic acid produces a hierarchical structure of β-MnO2 and Mn2O3. To optimize the degradation of Palm Oil Mill Waste which contains a high concentration of pollutants, it still needs to be improved. From the parameters pH, chemical oxygen demand, oil & grease, and total suspended solids, the best degradation efficiency of each parameter was achieved at pH 8.8, 16.3%, 43.5% and 56.6%.

Abstract

Kualu Nenas Village is a village that produces quite a lot of jackfruit flesh in the form of chips for sale. UMKM that process jackfruit as the main ingredient will have an impact on the amount of easily damaged organic solid waste from the jackfruit itself, such as jackfruit seeds. However, in processing jackfruit seeds are more often just boiled or fried as a snack. One way to process jackfruit seed waste is to make nuggets. Socialization and nugget making training activities were carried out in Kualu Nenas Village with the PPK Ormawa HIMAKI team. The aim of this activity is to increase knowledge and skills for the people of Kualu Nenas Village in processing waste, optimizing natural resources, and improving the community's economy by selling jackfruit seed nuggets. The activity began with a presentation through socialization of material about waste jackfruit seeds and nuggets in general, then continued with practical training in making nuggets from waste jackfruit seeds. The results obtained from this community service activity are that the community can understand the techniques for processing jackfruit seed waste into nuggets well as shown by the achievement percentage ≤ 74%.
