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.
