“…Umumnya pemanfaatan singkong hanya terbatas pada dagingnya sebagai bahan pangan sedangkan bagian kulitnya sebagian dimanfaatkan sebagai pakan ternak dan selebihnya dibuang (Santoso et al, 2014). Pemanfaatan kulit singkong sebagai pakan ternak cukup terbatas karena mengandung cyanogenic glucosides yang dapat meracuni hewan ternak (Suprabawati et al, 2018) sehingga selebihnya menjadi limbah karena dibuang begitu saja. Hal ini menjadi ancaman pembuangan di sebagian besar negara yang menjadikan singkong sebagai makanan pokok (Oghenejoboh, 2015).…”

“…Kulit singkong merupakan biomassa lignoselulosa dengan kandungan utama hemiselulosa yaitu 23,9% dan lignin 7,5% (Widiarto et al, 2019) yang memiliki potensi besar untuk digunakan sebagai prekursor karbon aktif. Seperti pada penelitian (Suprabawati et al, 2018) karbon aktif kulit singkong menunjukkan kemampuan signifikan untuk pengikatan logam dari larutan berair yaitu pada penjerapan ion Pb 2+ yang mencapai 98%. Selain itu dengan adanya kandungan unsur karbon yang cukup banyak yaitu sekitar 59,31% (Setyoningsih & Indarti, 2018) serta kaya akan gugus karboksil, hidroksil dan amino menjadikan kulit singkong sangat berpotensi sebagai prekursor karbon aktif.…”

Cassava peel is a natural material that is still underutilized even though has the potential as an alternative to activated carbon precursors. In the synthesis of activated carbon, the impregnation ratio and activation temperature are important factors that affect the characteristics of the activated carbon produced. This study aims to determine the effect of variations in the impregnation ratio (carbon: H3PO4) and activation temperature on the characteristics of activated carbon from cassava peel (CPAC) and to determine the optimal conditions in the manufacture of CPAC. In this study, CPAC was produced by treatment with various impregnation ratios of 1:5, 1:6, 1:8, 1:10, and 1:12 (w/w, carbon: H3PO4 30%) and a range activation temperature variation of 400 - 800 °C in the furnace for 60 minutes. The CPAC results were analyzed using FTIR, XRD, and SEM-EDX instruments. Based on the results of the FTIR test, it is showed that the characteristics of CPAC contain functional groups O–H, C–H, C≡C, C=C, C–O/P=O with an impregnation ratio of 1:6 (w/w, carbon: H3PO4 30%) and an activation temperature of 500 °C for 60 minutes to be the optimal conditions in the production of CPAC. The CPAC has an amorphous crystalline character based on XRD analysis and a hollow (porous) surface based on SEM analysis. The results of the EDX test showed that CPAC consisted of the elements carbon (C), oxygen (O), nitrogen (N), phosphate (P), sodium (Na) with the respective percentages being 72.60%, 15.52%, 10 .32%, 1.09%, and 0.47% respectively.

“…Penelitian ini dilakukan dalam beberapa tahapan proses, yaitu pembuatan karbon aktif dari kulit singkong, penentuan kondisi optimum kinerja karbon aktif pada senyawa fosfat artifisial, dan Aplikasi karbon aktif pada senyawa fosfat limbah laundry. Proses pembuatan karbon aktif dari kulit singkong mengacu pada metode penelitian Suprabawati et al (2018) dengan modifikasi. Secara umum pembuatan karbon aktif melalui tahapan dehidrasi, karbonisasi kemudian dilanjutkan dengan aktivasi mengahasilkan karbon aktif (Utomo, 2014).…”

“…Adsorben yang dibuat pada penelitian ini belum optimal dalam menjerap fosfat. Namun pada sampel dan metode yang sama, adsorben kulit singkong yang diaktivasi KOH 0,4 M memiliki kemampuan yang baik dalam mengadsorpsi ion logam Pb 2+ dengan efisiensi 98% (Suprabawati et al, 2018). Adapun penjerapan fosfat menggunakan karbon aktif dari kulit durian memiliki kapasitas adsorpsi sebesar 2,39 mg/g pada waktu kontak optimum 25 menit dan berat adsorben 1 g (Rajagukguk, 2018).…”

Cassava peel has high carbon content. It becomes potential as an adsorbent in adsorbing laundry phosphate compounds. Utilization of cassava peel into activated charcoal is an effort to reduce waste from the cassava processing industries. This study used two types of activated carbon from cassava peel, i.e. acid activated charcoal using HCl 0.4 M and alkaline activated charcoal using KOH 0.4 M. The objectives of this research were to determine: (1) the optimum contact time of adsorption at 30, 60, 90, 120, 150, and 180 min treatment time; (2) the optimum pH value of adsorption at pH 4, 6, 8, and 10; and (3) the adsorption capacity using adsorbent concentration treatment of 0.5%, 1%, 1.5%, 2%, and 2.5% (w/v). The experimental design used was a Single Factor Randomized Block Trial Design, ANOVA-DNMRT statistical analysis, and linear graphic for descriptive analysis. The analysis of the activated charcoal showed that water contents of the acid activated charcoal and the alkaline activated charcoal were 3.49% and 2.89%, respectively; the ash contents were 6.78% and 9.03%, respectively. The water content and ash content meet the standard of SNI 06-3730-1995. The performance test showed that the optimum contact time and pH of acid activated charcoal were 30 min and pH 4, while the alkaline activated charcoal was 90 min and pH 6. The adsorption capacity of acid active charcoal was 0.26 mg/g and the adsorption capacity of alkaline active charcoal was 0.49 mg/g. Activated carbon from the cassava skin can be used as an adsorbent to reduce phosphate concentrations in laundry waste.
