Abstract

Minyak atsiri merupakan campuran senyawa organik yang dihasilkan dari berbagai bagian tumbuhan, seperti daun, bunga, batang, akar, dan biji. Minyak ini memiliki sifat khas, seperti mudah menguap, beraroma kuat, dan tidak larut dalam air, tetapi larut dalam pelarut organik. Proses ekstraksi minyak atsiri dilakukan melalui berbagai metode, di antaranya distilasi uap, ekstraksi pelarut organik, dan cold pressing. Distilasi uap merupakan metode yang paling umum digunakan, di mana uap panas diarahkan melalui bahan tumbuhan untuk menguapkan minyak, yang kemudian dikondensasikan dan dipisahkan dari air. Pemilihan metode bergantung pada karakteristik bahan baku dan produk akhir yang diinginkan. Pengabdian masyarakat dengan tema "Mengenal Lebih Dalam Tentang Minyak Atsiri" dilaksanakan di SMKN 5 Dumai untuk memberikan edukasi dan pelatihan teknis kepada siswa terkait proses produksi minyak atsiri, mulai dari persiapan bahan baku, teknik distilasi, hingga analisis kualitas produk. Siswa diperkenalkan pada alat-alat produksi seperti alat distilasi uap sederhana, prinsip kerja kondensor, serta metode pemisahan minyak dari distilat. Selain itu, dijelaskan pula aspek penting dalam pengendalian proses, seperti suhu, tekanan, dan waktu distilasi, untuk mendapatkan hasil yang optimal dan sesuai dengan standar industri.

Abstract

Conventional handling of biomass waste, such as burning biomass, can cause other problems, and is not effective. Another common handling method is utilizing biomass waste. Second, conventional handling does not significantly reduce the amount of biomass waste. Microwave heating uses several power parameters and activation time to determine the effect of power and activation time on iodine number and surface area [25]. Activated charcoal is used as a raw material because it is hard charcoal and has good quality, and microwaves are used because it saves energy and time. Microwave treatment to study the effect of concentration and time of microwave irradiation separately on iodine number and adsorption capacity. The results of the FTIR spectra show that activated carbon has an –OH group. The results of the adsorption test showed that the activated carbon that had been prepared was able to absorb ions at the optimum concentration. Adsorption isotherm studies were carried out using the Langmuir equation. Microwave irradiation time also has a significant effect on the quality of activated carbon in the microwave irradiation time range

Abstract

Indonesia is the second largest producer of palm oil in the world today after Malaysia. Since 2003, the amount of palm oil production in Indonesia has reached approximately 9.9 million tons per year. According to (BPS 2021), the area of oil palm land in North Sumatra reached 442 072.76 hectares. This research will purify used cooking oil using natural adsorbents by utilizing palm frond waste. Palm fronds are chopped into powder, then sifted with sizes of 50, 70 and 100 mesh after which they are weighed with weights of 1.5, 3 and 4.5 grams. Oil palm frond adsorbents with mass variations of 4.5 grams have the greatest adsorption power in reducing used cooking oil and the best adsorption kinetics based on the correlation coefficient is the pseudo second order equation.

Abstract

The statistics center in 2021 stated that North Sumatra is the second largest palm oil-producing province in Indonesia with a plantation area of 1,373.30 Ha. The use of cooking oil in Indonesia in 2021 was 18.4 million tons and increased by 6% from the previous year. This research utilizes palm fronds for the manufacture of adsorbents in cooking oil refining. The method used is carbonization with the help of pyrolysis. The carbon is chopped into powder and divided by variations of 1.5, 3, and 4.5 grams. Each gram is stirred using a shaker with speed variations of 50, 70, and 100 rpm. Turbidity is tested using a turbidimeter once every 20 minutes for 180 minutes. The results of the analysis showed that the best adsorbent weight in reducing used cooking oil was 4.5 grams with a turbidity level of 15.5 NTU and stirring of 100 rpm.

Abstract

Sodium chlorate (NaClO3) is used to produce clorine dioxide (ClO2), which is used in the bleaching process in the pulp and paper industry. Sodium chlorate is produced in the industry by electrolysis process. This electrolysis process produces 2 main products, namely hydrogen and sodium chlorate. hydrogen is used in the process of making hydroclorid acid (HCl) and sodium chlorate is used in the process of making ClO2. In the process of making chlorate there are several things that must be considered, including: pH, oxygen levels in the degasifier, conditions of the hypo tower system, salt and chlorate concentration, and K cell factor. Based on the results of the above analysis, it can be seen that the acid wash cell is able to reduce the K factor of the cell. Do not run the electrolyzer if the cell voltage is above 3.5 volts. This is because at a voltage above 3.5 volts oxygen formation occurs, if oxygen meets hydrogen gas from electrolysis can cause an explosion.

Abstract

Oil palm fronds are an agricultural waste with potential application as a raw material for activated carbon due to their lignocellulosic content, which includes cellulose, hemicellulose, and lignin, enabling their function as an adsorbent. In this study, oil palm fronds were carbonized by pyrolysis at a temperature of 350°C, size-reduced to 100 mesh, and subsequently activated using a 0.1 M H₂SO₄ solution for 3 hours, then drying by oven at 70°C. 100 mL of the Siak River sample was added with 3 grams of activated carbon for the adsorption process, then shaken every 20 minutes for 3 hours. Turbidity analysis was conducted using a turbidimeter. The results indicated that the lowest turbidity values were obtained in the morning, namely 16.8 NTU at the upper section and 21.7 NTU at the lower section. This is attributed to the minimal level of community activities around the Siak River during the morning period.

Abstract

Penelitian ini bertujuan untuk mengembangkan karbon aktif dari tandan kosong kelapa sawit (TKKS) melalui proses pirolisis tanpa aktivasi pada suhu 350 °C untuk penggunaan pemucatan (bleaching) crude palm oil (CPO) di PKS Sei Pagar, PTPN IV Regional III, Riau. Latar belakang penelitian didasarkan pada tingginya ketersediaan tandan kosong kelapa sawit sebagai limbah padat pabrik kelapa sawit serta kebutuhan adsorben alternatif yang lebih berkelanjutan untuk mengurangi ketergantungan terhadap bleaching earth dan meminimalkan limbah spent bleaching earth (SBE). Metode penelitian bersifat eksperimental laboratorium yang meliputi pengeringan TKKS, proses pirolisis, penghalusan, dan pengayakan. Hasil penelitian menunjukkan bahwa karbon aktif yang dihasilkan memiliki rendemen sebesar 7,67% dan kadar air 11,84% sehingga memenuhi persyaratan SNI 06-3730-1995 (kadar air maksimum 15%). Pengaplikasian karbon aktif pada proses bleaching CPO menunjukkan hasil penurunan FFA dari 4,69% menjadi 1,66% dan 1,63%, penurunan DOBI dari 2,87 menjadi 2,76 dan 2,82, penurunan kadar air CPO dari 0,15 menjadi 0,07 dan 0,06, serta perubahan warna dari oranye gelap menjadi kuning terang. Dengan demikian, karbon aktif TKKS berpotensi digunakan sebagai alternatif adsorben dalam proses pemucatan CPO dan mendukung penerapan konsep pengelolaan limbah berbasis ekonomi sirkular di industri kelapa sawit. Hasil ini membuka peluang penerapan skala industri yang ekonomis, ramah lingkungan, dan berkelanjutan nasional sawit.

Abstract

Indonesia, as the world's largest palm oil producer, generates approximately 26 million tons of palm shell waste annually. This study aimed to evaluate the effect of contact time of NaOH-activated palm shell biosorbent on reducing water quality parameters in the WTP (Water Treatment Plant) sand filter unit at PKS PTPN IV Regional 3. Palm shells were prepared through washing, drying at 105°C, grinding, and sieving at 100 mesh. Chemical activation using 1 M NaOH for 2 hours without carbonization process resulted in increased material porosity. Adsorption testing was conducted at contact times of 30, 60, 90, and 120 minutes with adsorbent dosage of 10 grams per 100 mL water sample. Results showed that adsorption efficiency for Fe parameter reached 88-95% at 90 minutes contact time, turbidity reached 85-93% at 60 minutes, pH increased from 5.5 to 6.5-7.0, and TDS decreased from 27 to 25 mg/L. Kinetic analysis indicated that adsorption followed the pseudo-second-order model with determination coefficient R² = 0.998 for Fe and R² = 0.999 for turbidity, indicating chemisorption mechanism. Palm shell biosorbent without carbonization proved effective as an environmentally friendly alternative for water purification in palm oil industry WTP systems.

Abstract

As an adsorbent to reduce FFA levels and as a source of Calcium Oxide (CaO) for heterogeneous catalysts. Eggshells were calcined at 900°C for 4 hours to convert CaCO3 into active CaO, which was confirmed through XRD characterization with high crystallinity. The synthesis process was carried out in two stages: adsorption pretreatment and transesterification. The results showed that the adsorption process was able to significantly reduce the FFA content of used cooking oil from 4.5% to 0.8%. Optimum transesterification conditions were achieved at an oil:methanol molar ratio of 5:1, a catalyst weight of 3% (w/w), a temperature of 60°C, and a reaction time of 2 hours, resulting in a biodiesel yield of 92.4%. The physicochemical characteristics of the biodiesel produced include: density of 870 kg/m³, kinematic viscosity of 4.3 cSt, acid number of 0.42 mg-KOH/g, iodine number of 54 g-I2/100g, saponification number of 165.495 mg-KOH/g, and cetane number of 53. All test parameters have met the quality standard of SNI 7182:2015, indicating that duck eggshell waste has great potential as an economical and environmentally friendly catalyst raw material.

Abstract

Waste management in Padang City is currently facing a critical phase with the Air Dingin Landfill predicted to reach full capacity in 2026 and having a worrying Environmental Risk Index (IRL). This problem is exacerbated by a large fiscal shortfall, where the regional budget allocation is far less than the ideal requirement of IDR 133 billion per year. This study aims to evaluate the effectiveness of waste policies and formulate a communal-based integrated management strategy as a sustainable solution. The research method uses a qualitative approach through literature studies, a review of Regional Regulation Number 21 of 2012 and flagship government programs such as “Padang Bagoro” and “Padang Mamilah”, as well as secondary data analysis of waste management data (SIPSN). The results of the analysis indicate a functional gap between seasonal social participation and low sorting behavior at source, as well as weak law enforcement due to limited supervisory personnel. This study recommends policy restructuring through a communal-scale management approach (RT-RW) that maximizes communal management and integration with the sub-district Waste Management Institution (LPS) and industrial sector to reduce the logistical burden and extend the technical life of the landfill.
