Abstract

SLS (Sodium Lauryl Sulfate) and LAS (Linear Alkyl Sulfonate) are active ingredients in detergents which have a negative impact on living things and the environment. To overcome these problems, one of the environmentally friendly alternative ingredients is waru leaves. The purpose of this study was to determine the benefits of waru leaves in their use for washing cloth, knowing the effectiveness of waru leaves as an active ingredient in cleaning stains and knowing the level of contamination of COD waste waru leaf extract. The composition of the detergent formula uses the experimental method with 1 factor, namely the concentration of waru leaves (80%, 82%, 84%, 86%, 88%). The sample selection stage is based on the parameters of pH, foam height, optimal viscosity. From this stage, two best formulas were obtained, namely 80% and 82% waru leaf extract. The two best samples were washed so that the best formula was 82%. Further testing is carried out to measure the level of waste contamination. The sample had a pH of 7.56, foam height of 4.10 cm, viscosity of 539.0, white degree of WI-CIE 155.02 and level of COD contamination of 308.25 mg / l. These results can prove that waru leaves can be used as detergent raw materials.

Abstract

Generally the measurement of standard time is only based on how many product units are produced per unit of time, without regard to the movements carried out by the operator. The movements carried out by the operator in completing the work are very necessary to be evaluated, considering that many of the movements of the operator that are not effective will slow down the completion time of the work, which in turn affects the product output. Movement study is an analysis carried out on several movements of the worker's body in completing work. Through the study of motion the standard time can already be determined by synthesizing the standard times of the parts that have been labeled. Based on the standard time calculation of the results of the motion study, it was obtained the results of 25,988 bowl component units and 84,485 APP lid box components. If 25% of the available time is cut off by the needs of the operator, namely the provision of adjustment factors and the allowance factor for operators of the target of 10,000 APP box units, it is still very possible.

Abstract

Jatiluhur Reservoir is one of the largest reservoirs in West Java which has many functions, one of which is for aquaculture with the KJA system. But along with the development of KJA activity in the Jatiluhur Reservoir it has become one of the factors causing the decline in water quality of the Jatiluhur Reservoir. Therefore the Purwakarta Regency government made a program called Operation Jatiluhur Jernih Lake through the Decree of the Regent of Purwakarta No.523.31.05 / Kep.286-DLH / 2017. This program had a purpose to curb a number of cageculture in Jatiluhur Dam. The purpose of this study was to analyze the effectiveness of the program as an effort to save the condition of reservoir water and to analyze the impact of the program to the sosio-economic condition of the farmer. The methode that used in this study was quantitavie methode based on the effectivity value from the quisioner and the qualitative method by analyzing data from interview. the results of this study indicate that the Jatiluhur Lake Operations program is running quite effectively with the acquisition of a score of 60.37%, which means this program has a pretty good value in efforts to save the water conditions of the Jatiluhur reservoir. But on the other hand this program has a significant impact, especially on the socio-economic conditions of farmers such as decreasing income levels, rising potential for unemployment, increasing levels of difficulty in fulfilling the needs of life, and also reducing the supply of fish in the Jatiluhur Reservoir

Abstract

In line with industrial development and scientific and technological advancement, the use of metals cannot be separated from human life. Aside from benefits, the rapidly increasing industrial developments also give negative impact from their heavy metal waste. Some electroplating waste treatment methods are studied in this research, specifically electrodeposition method, electrocoagulation, and pH 9 hydroxide coagulation method. This research aimed to determine the most effective method and conditions from the 3 methods mentioned above in reducing contents of nickel in the wastewater. The artificial wastewater was made to have the same concentration to waste from electroplating industry; specifically 2154.20 mg/L. The most effective reduction of nickel for this method occurs at 6 volts with final concentration of 404.86 mg/L. The treatment result from electrodeposition was then further processed through two different processes, a electrocoagulation method and pH 9 hydroxide coagulation method. Electrocoagulation process was done for 1 hour with variation in voltage at 5; 7, 5; and 10 volts. Metal Al was used at the anode, while metal Cu was at the cathode. The optimum voltage for this process occurs at 10 volts with final concentration of nickel at 164,98 mg/L, nickel elimination efficiency was at 59.25 %, specific energy at 1.0777 kWh/kg and current efficiency at 32.3 %. Sample from electrodeposition which was processed further with pH 9 coagulation process produced final nickel concentration at 25.59 mg/L, nickel elimination efficiency was at 93.68 %. Keywords: electrocoagulation; electrodeposition; electroplating; hydroxide coagulation; nickel.

Abstract

Dry Processing was generally consist of two model mathematics, emphirical and mechanistic model. CDRC (Characteristic Drying Rate Curve) and REA (Reaction Engineering Approach) are one of mechanistic model to find physic condition in all term, which is emphirical model hasn’t. The results obtained by simulation are shown with the temperature profile and the moisture content of mango tissues that has previously been validated according to the literature. Mean square error and explained variation value showed similarity value between moisture content and temperature. Experiment data for REA using drying temperature at 338K and Y at 0,0134kg H2O/kg dry air. CDRC is divided by two approaching model, Constant Rate Period (CRP) and Falling Rate Period (FRP) at temperature 338K. To find the relative activation energy as amount of losing moisture content, temperature used at 328K. The result showed are CDRC and REA model relatively similar, which is CDRC closer to experiment data. For drying curve, moisture content of mango tissues is descending exponentially at the time of drying. But for temperature curve against time of drying, temperature of mango tissues is ascending exponentially.

Abstract

Inventory Control is part of production planning that needs to be considered in more detail. In the case of raw material inventory, if there is a delay or a vacancy in the stock, then the worst risk is termination of the production process. In order to avoid these conditions, an inventory model is made that includes backorder elements, with the hope that there will be no shortage of raw materials, even if it does, then there will be a substantial penalty. In the case of PT ABC, it resulted in inventory costs is Rp 1.739.774.271,00and this reiterates that the inventory needs to be managed well because of the large value that must be managed
