Published: July 2023

In this study, sawdust as a cheap method and abundant raw material was utilized to produce active carbon (SDAC). Physiochemical activation was utilized where potassium hydroxide used as a chemical activating agent and carbon dioxide was used as a physical activating agent. Taguchi method of experimental design was used to find the optimum conditions of SDAC production. The produced SDAC was characterized using SEM to investigate surface morphology and BET to estimate the specific surface area. SDAC was used in aqueous lead ions adsorption. Adsorption process was modeled statistically and represented by an empirical model. The highest specific surface area of SDAC was 688.3 m2/gm. Langmuir and Freundlich isotherms were used to fit the adsorption process, where equilibrium data was best represented by Langmuir isotherm model. Pseudo-first order and pseudo-second order equations were used to study adsorption kinetics, lead adsorption on SDAC fitted pseudo- second order more adequately. Best removal efficiency was found to be 99.63% with highest adsorption capacity of 19.92 mg/g.

Legal Entity Administration System or SABH (formerly known as Sisminbakum) is a type of legal service provided to the business community in the process of ratifying PT legal entities, granting approval for changes to the articles of association of PT, receiving notification of changes to the articles of association of PT and changes to PT data, as well as notification of information others electronically (via computer networks and the internet), organized by the Directorate General of General Legal Administration (Ditjen AHU) at the Ministry of Law and Human Rights of the Republic of Indonesia. Prior to 2000, the process of legalizing a limited liability company was done manually, starting from receiving files which included checking names, payments and making control cards, so it took quite a long time. The enforcement of the SABH began on October 4, 2000 based on the Decree of the Minister of Justice and Human Rights of the Republic of Indonesia number M-01.HT.01.01 of 2000.
To establish a company, it must meet the requirements and procedures that have been determined by the Limited Liability Company Law. The establishment of a Limited Liability Company must meet the following requirements: a.) The company is established by two or more persons with a notarial deed drawn up in the Indonesian language, b.) Each company founder is required to subscribe to shares at the time the company is established, c.) The company obtains status of a legal entity on the date of issuance of a ministerial decree concerning the legalization of a legal entity of a company and d.) After the company has obtained the status of a legal entity and the shareholders have become less than two persons, within a period of no later than six months as of the said situation, the shareholder concerned is obliged to transfer part of its shares to other people or the company issues new shares to other people. With the enactment of the Decree of the Minister of Justice and Human Rights of the Republic of Indonesia number M-01.HT.01.01 of 2000 concerning the implementation of the administrative system of legal entities, the process of legalization of legal entities is carried out electronically replacing the old system, namely manual registration of legal entities.
