Abstract

Pemanfaatan limbah plastik polipropilena dan tandan kosong kelapa sawit dilakukan dengan cara mengolah serta menggabungkan limbah plastik polipropilena dengan pati tandan kosong sawit menjadi plastik biodegradable yang mudah terurai di alam. Modifikasi komposisi yang digunakan pada pembuatan plastik biodegradable adalah limbah plastik dan pati tandan kosong sawit adalah (80:20; 70:30; 60:40). Metode pencetakan plastik biodegradable adalah dengan metode kempa tekan panas. Hasil karakterisasi plastik biodegradable dengan komposisi optimum yaitu pada perbandingan 60:40 menunjukkan harga kekuatan tarik 6,54 N/m2 dan kemuluran 2,42%. Hasil analisa sifat biodegradable-nya didapatkan penurunan massa yang telah ditanam selama 1 bulan yaitu pada tanah sampah sebesar 6,78% dan analisa dengan FT-IR ditemukan bilangan gelombang 1165 cm-1 yang menunjukkan gugus fungsi C-O bending yang khas untuk menunjukkan ikatan antara limbah plastik polipropilena ter-grafting maleat anhidrida dan pati yang didukung dengan bilangan gelombang 1590-1560 cm-1 yang menunjukkan gugus fungsi C=C pada maleat anhidrida dan polipropilena yang terikat silang.

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 research about “Acid-Base Indicator Manufacturing from Avocado’s Peel” had done. The research aims to make acid-base indicator from avocado’s peel in paper form as chemistry’s learning media. Polytechnic ATI Padang was the place that the research held with avocado’s peel as the sample matter.  The genre of the research was descriptive with qualitative approaching. It had two phases which was manufacturing and testing of paper indicator from avocado’s peel. Data was collected by acid-base indicator from fruit’s peel’s paper test observation. Data analysis showed interval up to 30 days for avocado’s peel based paper indicator to express a different color in acid, base, and neutral solution. The Conclusion of the research was acid-base indicator from avocado’s peel paper was stable and could be used as acid-base indicator and learning media.

Abstract

This research about “Acid-Base Indicator Manufacturing from Banana’s and Dragon fruit’s Peel” had done. The research aims to make acid-base indicator from banana’s and dragon fruit’s peel in paper state as chemistry’s learning media. This research was conducted in Polytechnic ATI Padang with banana’s and dragon fruit’s peel as the sample. Descriptive with qualitative approaching was the style of this research. It had two phases which was manufacturing and testing of paper indicator. Data was collected by acid-base indicator from fruit’s peel’s paper test observation. Data analysis in 30 days showed acid-base indicator from banana’s and dragon fruit’s peel’s paper could expressed a different colour in acid, base, and neutral solution. These researches have conclusion that acid-base indicator from banana’s and dragon fruit’s peel’s paper in 30 days interval could be used as acid-base indicator and learning media.

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.

Abstract

Penggunaan fly ash (FA) pabrik kelapa sawit (PKS) sebagai adsorben dapat meningkatkan nilai guna dalam pengolahan limbah padat PKS. Penelitian ini bertujuan mengkaji kemampuan FA sebagai adsorben untuk pemucatan (bleaching) crude palm oil (CPO). Adsorben FA diharapkan dapat mengurangi atau menjadi alternatif pengganti adsorben komersial bleaching earth (BE) di industri refinery minyak sawit. Penelitian diawali dengan proses aktivasi adsorben FA secara kimia (penambahan larutan asam oksalat) dan fisika (pemanasan menggunakan furnace). CPO dilakukan degumming terlebih dahulu menggunakan asam fosfat. Selanjutnya, adsorben hasil aktivasi dan adsorben komersial BE digunakan dalam proses bleaching CPO dengan jumlah adsorben dan suhu bleaching yang divariasikan. CPO hasil bleaching dilakukan uji warna dengan lovibond tintometer untuk menentukan kemampuan penyerapan adsorben. Penurunan warna CPO terendah diperoleh pada adsorben FA dengan aktivasi kimia pada konsentrasi asam oksalat 1,5 M (FA 1,5 M) dan aktivasi fisika pada suhu 400°C (FA 400°C) masing-masing sebesar 16R/16Y dengan jumlah adsorben 1,5% dan suhu pemucatan 120°C. Berdasarkan hasil uji gum, penggunaan dosis adsorben 1,5% menunjukkan tidak adanya sisa gum pada CPO hasil bleaching. Selain itu juga dikaji kemampuan penyerapan dari kombinasi adsorben FA dan BE dengan rasio yang divariasikan. Penurunan warna CPO terbaik sesuai standar mutu industri refinery sebesar 17R/17Y diperoleh pada rasio adsorben BE:FA sebesar 1:3 (adsorben campuran BE:FA 1,5 M dan BE:FA 400°C). Kadar FFA CPO hasil bleaching secara keseluruhan mengalami kenaikan dibanding dengan CPO awal yaitu sebesar 7,719%.
