Abstract

The most commonly used chemicals for making the soaps are less safe for human skin. Soap contains ingredients that are safe and nutritious for the skin need to be developed. Seaweed is one of the potential mariculture commodities in Bangka Belitung Islands Province.. The purpose of this activity is the utilization of seaweed for making the soap using direct experimental methods in order to generate the profit. Business analysis was performed to determine the advantages and feasibility. This study revealed that seaweed can be used as raw material for making safe and profitable soap with a soft texture. Keywords: soap, seaweed, safe, nutritious, soft

Abstract

The process of tin ore mining in TB 2.1 is conducted by channeling slurry (the mixture of ore and water) from the stock pile into the washing unit by using slurry pump. Now, TB 2.1 is planning block 3 for the operation of tin ore production proceess. Thus, a good technical planning in accordance with the characteristic of tin ore in TB 2.1 and evaluation of operating system design in Block 1 are necessary. The sample of tin ore concentrate is taken as many as 250 gr from the washing unit to detect P80 of particle size distribution (PSD) of sample. The data of sucker and pressure pipe’s lenghth, store tank’s height, quantity of primary and secondary jig and tin ore monthly production are required to furthermore plan the mining design, washing plant and equipment needs in the drying unit. Based on the research findings, It is obtained the grain size distribution of tin ore is 1.001 mm, so that the amount of lifting velocity is 3.27 m/s. Slurry pump discharge with a pipe’s diameter of 10 inches is 54 m3/hour, while total head of mining design is 30.23 m. Width of launder required is 6.5 m and equipped with two Grizzlies. Washing plant requires three units of primary Jig (2 × 3 cell) and a unit of secondary jig (2 × 3 cell). Adding rotary vibrating screen, shaking table and rod mill are necessary for process optimization in the drying unit.
