Jumlah kandungan selulosa dalam bahan alam berupa biomassa menunjukkan potensinya menjadi adsorben berdasarkan karbon yang dapat dihasilkan. Salah satu biomassa yang dapat dimanfaatkan sebagai adsorben adalah limbah kulit pisang kepok yang ketersediaan banyak dan mengandung selulosa sebanyak 18,71%. Penelitian dilakukan dengan variasi perlakuan delignifikasi dan tanpa delignifikasi pada kulit pisang kepok untuk menjadi biosorben dan karbon aktif. Semua jenis adsorben kemudian diaktivasi menggunakan aktivator H2SO4. Hasil analisis karakteristik SEM – EDX, FTIR, dan BET menunjukkan bahwa kombinasi perlakuan delignifikasi dan karbonasi (sampel A) dapat meningkatkan kadar karbon yang terkandung dalam sampel adsorben (pad hasil SEM ditandai dengan adanya struktur selulosa yang lebih beraturan dan pori kecil). Dari hasil EDX, sampel A terindikasi mengandung unsur karbon tertinggi yaitu 78,65% berat dan diperkuat dengan hasil analisis FTIR dimana sampel A memiliki rentang peak ikatan C=C dan C-H lebih luas (pertanda selulosa yang sudah terpisah terkarbonasi dengan baik sehingga menghasilkan unsur karbon). Selain itu, kombinas perlakukan proses delignifikasi dan karbonisasi juga meningkatkan luas permukaan pori keseluruhannya dibandingkan dengan variasi lainnya dengan nilai sebesar 83,381 m2 /g. Dari penelitian ini tampak bahwa pretreatment proses delignifikasi dapat meningkatkan karakteristik adsorben dari nlimbah kulit pisang kepok dengan peningkatan kadar karbon terkandung dan luas permukaan

The growth of Indonesia's cosmetics industry reached 21.9%, with 913 companies in 2022 and 1,010 companies by mid-2023. Among the total products from local cosmetic companies, the largest market segment is personal care. Shampoo and bodywash are the two main categories of personal care cleansing products. Foam is an important indicator of product quality; however, technically, foam does not always correlate with the cleaning strength of a product. Nevertheless, consumers expect shampoos and body washes to lather easily and produce abundant foam. The foaming ability of a product is influenced by several factors, one of which is the addition of foam boosters. Cocamidopropyl betaine (CAPB) is the most used foam booster and is produced on a large scale. Another foam booster is lauryl hydroxysultaine (LHS) which has better foam-producing ability than CAPB. This study aims to determine the right formulation of LHS addition in shampoo and bodywash thus it meets the specified requirements. Shampoo and bodywash were prepared with several formulations, the samples were then tested for their viscosity, foam quality, and irritation potential. The results showed that LHS performed better than CAPB for the three parameters above. It was obtained that a dose of 2% LHS gave a better effect than 3% CAPB. It is, therefore, quite profitable from an economic and environmental perspective.

Palm kernel shell (PKS), a byproduct accounting for up to 60% of palm oil production, is often used solely as fuel. However, due to its silica content, PKS can also function as an adsorbent. This study aimed to evaluate the impact of delignification on the quality of PKS as an adsorbent, specifically its ability to adsorb free fatty acids from used palm cooking oil. Delignification was performed using a microwave-alkali (Mw-A) method. Initially, PKS was cleaned, ground into powder, and sieved to 25 mesh. The powder was then delignified using Mw-A before activation with NaOH concentrations of 10%, 20%, and 30%. The temperature settings were 70⁰C, 80⁰C, and 90⁰C, with durations of 30, 35, and 40 minutes. The delignified PKS was carbonized at 400⁰C for 2 hours to produce the adsorbent. The adsorption capacity of each adsorbent was tested on free fatty acids in used palm cooking oil. Results indicated that the Mw-A assisted delignification significantly enhanced the adsorption efficiency, achieving a 55% adsorption capacity at 30% NaOH concentration, 90⁰C temperature, and 35 minutes. In comparison, PKS without Mw-A assisted delignification adsorbed only 32% of free fatty acids. It was showed that the adsorption kinetics belong to pseudo-first order reaction. Thus, delignification proved to be an effective pretreatment method to enhance PKS's adsorption capacity.

Palm oil is one of the Indonesian prima donna whose total national production is increasing every year. Palm oil can be used as a raw material for production of cooking oil products, industrial oil needs and energy sources. The base color of Crude Palm Oil (CPO) is due to the presence of a high β-carotene content in palm oil which can produce a red color in CPO. For this reason, it is necessary to bleach CPO. Most of the palm oil industry currently uses adsorbents as a pale material in the Bleaching process. This research does several things related to the process of making palm oil in general, the process is the production of adsorbents with activated adsorbents, removal of gum with H2SO4, bleaching process with adsorbents and analysis of bleaching oil (BPO). The experimental results show that zeolite can be used as an adsorbent for the bleaching process of palm oil. Zeolite has been activated by chemical methods using H2SO4 solution before being used as an adsorbent. From the experimental results, the best results for the application of β-carotene were obtained from 3% activated zeolite with 15% by weight zeolite.
