Opis:
Batteries are electric cells that use a reversible electrochemical process. One of the important components in the battery is the electrode. Electrodes in conventional batteries generally contain the B3 material. This study aimed to produce and characterize the bioelectrolytes made from blood clam shells and sugarcane bagasse. This study consisted of four stages, namely the stage of calcination of blood clam shells, the stage of hydrolysis of sugarcane bagasse, the stage of making bioelectrolyte paste, and the stage of test parameters. The test parameters performed included calcined blood clam shell morphology analysis using SEM, composition and mineral analysis on blood clam shell ash using XRF (X-Ray Fluorcence), analysis using UV-Vis spectrophotometry, and analysis using FTIR spectrophotometry. The characterization of the bioelectrolytes was tested using an AVOmeter or a multimeter connected using a connecting cable and an alligator clip. The best bioelectrolyte results were obtained using a reaction time of 90 minutes and a concentration of acid solution 30% (v/v) with a mixture of shell ash and sugarcane bagasse paste in 1:1 ratio. The best power produced was 0.02 watts.

Opis:
In this study the focus is on the Enactment of Law No.17 of 2008, concerning shipping has experienced a lot of improvements in the function of Harbor Harbor Safety and Security. Safety and security issues in shipping are a big responsibility in port. Syahbandar (Harbourmaster) has the highest authority to carry out and supervise the fulfillment of the provisions in the legislation to ensure the safety and comfort of the voyage. The aim of this research is to examined the supervision system of port authority on the activities of loading and unloading dangerous goods in the port of tanjung perak surabaya. This type of research carried out in this research is to use descriptive research. The results of the study show that the application of work standards in the field is not yet optimal in accordance with the Standard Operating Procedures so that the task in supervising dangerous goods has not been carried out properly, inadequate facilities and infrastructures at the Port thus reducing the function of the Port in the supervision of dangerous goods and the limited number of personnel at the Port of Tanjung Perak so that services in the supervision of dangerous goods are less than optimal.
