Abstract

Agarwood is one of the forest products that can be utilized and has a high selling value. Agarwood contains essential oils which have many active compounds and contains a specific aromatic resin that is naturally formed as a form of defense against physical damage or microbial infection. Agarwood essential oil with good quality has a high economic value. This study aims to extract agarwood essential oil using ethanol as a solvent. The optimal yield of agarwood essential oil can be obtained by varying the particle size, the ratio of the weight of the agarwood biomass (kg) to the volume of the solvent (L), and the length of maceration (h). The results showed that the particle size of agarwood did notaffect the yield of agarwood essential oil. The results of the comparison of agarwood biomass with the volume of the solvent showed that the ratio of 1:9 (w/v) obtained the highest yield of 4.02% and the longest maceration time with the highest yield of 4.12% for 72 hours. However, 48 hours of maceration had a greater increase in yield compared to 72 hours of maceration. The increase in yield at 48 hours to 72 hours of maceration was only 0.22% when compared to the increase in yield at 24 hours to 48 hours of maceration, which was 0.56%.

Abstract

Plastik multilayer adalah limbah plastik yang banyak dikeluhkan oleh pemilik bank sampah, hal ini disebabkan plastik multilayer tidak dapat dijual ke pengepul. Salah satu pengolahan yang telah dilakukan yaitu mendaur ulang menjadi prakarya dengan tujuan memperlambat masuknya sampah plastik multilayer ke Tempat Pemprosesan Akhir (TPA). Oleh karena itu, dibutuhkan proses daur ulang menjadi material yang bersifat jangka panjang. Pada penelitian ini dilakukan proses daur ulang sampah plastik multilayer menjadi papan polimer menggunakan alat Hot press. Papan polimer dibuat dengan kombinasi sampah plastik HDPE sebagai matrik. Untuk mendapatkan kualitas papan polimer yang baik dilakukan penentuan komposisi yang tepat antara filler dan matrik. Pada penelitian ini akan divariasikan komposisi penyusun papan polimer. Selanjutnya untuk meningkatkan kualitas perlu ditambahkan zat adiktif berupa Maleic Anhydride (MAH) sebagai compatibilizer dengan variasi 5% dan 10 %. Hasil penelitian menunjukkan papan polimer dengan variasi 30% multilayer: 70% HDPE dengan penambahan MAH 10% memiliki nilai keteguhan tekan sebesar 90 kgf/cm3, nilai kerapatan tertinggi sebesar 1,16 gr/cm2, kadar air 0% dan daya serap air 0%. Hal ini menunjukkan bahwa komposisi limbah plastik multilayer dengan berat maksimal 30% dari berat keseluruhan dan penambahan MAH 10% memberikan hasil memenuhi SNI 03 – 2105 -2006.Penambahan MAH memberikan pengaruh dalam meningkatkan kualitas papan polimer. Kata Kunci : Plastik Multilayer dan Papan Polimer. Multilayer plastic is plastic waste that many waste bank owners complain about, this is because multilayer plastic cannot be sold to collectors. One of the processes that have been carried out is recycling into crafts with the aim of slowing down the entry of multilayer plastic waste into the Final Processing Site (TPA). Therefore, a long-term recycling process is needed. In this study, the process of recycling multilayer plastic waste into polymer boards was carried out using a hot press. Polymer board is made with a combination of HDPE plastic waste as a matrix. To get a good quality polymer board, it is done with the right composition between filler and matrix. In this study, the composition of the polymer board will be varied. Furthermore, to improve the quality of additives that need to be added in the form of Maleic Anhydride (MAH) as a compatibilizer with variations of 5% and 10%. The results showed that the polymer with 30% multilayer variation: 70% HDPE with the addition of 10% MAH had a compressive strength value of 90 kgf/cm3, the highest density value was 1.16 gr/cm2, 0% moisture content and 0% water absorption. This shows that the composition of multilayer plastic waste with a maximum weight of 30% of the total weight and the addition of 10% MAH gives results that meet SNI 03 – 2105 -2006. The addition of MAH has an effect in improving the quality of the polymer board. Keywords: Multilayer Plastic dan Polymer Board.

Abstract

CV. Amna Lab Aromaterapi Small and Medium Enterprises have started the citronella oil business in 2018. Some of its products such as soap, aromatherapy spray, propolis, and body oil have arrived in several big cities in Indonesia. However, since the Covid-19 pandemic, these SMEs have experienced difficulties, especially regarding the large capital costs and the price of citronella which has fallen drastically to 100% of the original price. Under these conditions, SMEs are constrained in the process of increasing productivity and lack production technology as well as marketing and management. The Community Service Team of the ATI Padang Polytechnic offers solutions to overcome these problems by providing alternative processing of citronella oil-based products to be aromatherapy candles and educating the SMEs on the product marketing strategies through e-commerce applications. The community service team tried resolving the delinquent by determining the amount of citronella oil that should be included and the composition variations of stearic acid, vegetable oil, and paraffin. The variations were tested in order to find the right comparison in making aromatherapy candles based on citronella oil. The team also searched and studied several references to analyze marketing strategies in accordance with SMEs CV. Amana Aromatherapy Lab. Considering the result of the experiments, it was identified that 1% of citronella oil could be added to the wax mixture while the exact composition of oil and paraffin was 1: 2. The stearic acid was unsuitable to applied since the candle product easily melted. E-commerce marketing strategies were used by utilizing advertisements on internet searches to expand the promotions.

Abstract

The use of palm oil mill fly ash (FA) as a low-cost adsorbent is one of the solutions for handling FA waste. In this study, the addition of dolomite is expected to improve the adsorbent performance. The aim of this study was to investigate the optimum FA-dolomite adsorbent composition and operating conditions for methylene blue adsorption. Different parameters were studied to optimize adsorption process such as the amount of dolomite, methylene blue flow rate, bed height and number of trays. FA-dolomite was converted into nano-adsorbent by sol-gel method which was coated on zeolite surface. Nano-adsorbents were characterized by XRF, FTIR, XRD and SEM. The adsorption capacity was tested by Spectrophotometer UV-Vis. XRF characterization showed that FA had the highest SiO2 content of 58.15%, while dolomite contained CaO of 52.72%. FTIR characterization detected the groups of Si-O-Si, Si-O-Al, Ca-O and Si-O. XRD characterization showed the average crystalline size of FA-dolomite 2% adsorbent was 28.56 nm and SEM characterization showed fine pores on the adsorbent surface. The highest adsorption efficiency obtained at FA-dolomite 2% was 97.364% and the lowest obtained at FA-dolomite 8% was 13.16% with a flow rate of 500 ml/h, adsorbent height of 9 cm and 3 trays. The greater the amount of dolomite added, the absorption efficiency decreases.
