Abstract

A palm oil plantation company often experiences late payment of wages. This happens because in the Operational Fund Request (PDO) creating process, which start from the input of document on the realization of work in the field up to the payment of wages, it does not run according to the specified time. The purpose of this research was to propose an improvement in the PDO creating process to prevent late payment of wages using the Value Stream Mapping (VSM) method. This research was conducted on February 20th – May 27th, 2017 at a palm oil plantation company in Central Sulawesi. Data processing is carried out by the step of using the value stream mapping principle. The result showed that the proposed improvement using value stream mapping (VSM) is to create a future state map which is a concept of improvement in the PDO creating process up to the payment of wages for harvesting employees by eliminating wastes in the current state map is a waiting/delay time.

Abstract

The problem always occurs with solar panel users, is the efficiency of solar panels and monitoring of solar panel generating systems. This causes the need for a solar tracker and monitoring system. The tracker system functions to increase the productivity of solar panels and the monitoring system serves to provide information on the condition of the productivity of solar panels. Internet of Things (IoT) allows devices to communicate like sending and receiving data. This study designed a tracker and monitoring system consisting of Arduino Mega, Esp8266-12F, LDR sensors and servo motors. Simple web application is able to provide information in realtime to users, so they can monitor the productivity of solar panels. When the solar panel generates electricity and passes the INA219 current sensor, the sensor will send an analog signal to Arduino Mega which will be forwarded to Esp8266 to send sensor data information sent to a simple web, then the data is accessed by the Google Chrome application as a user interface. The LDR sensor can detect the level of sunlight and send a signal to arduino mega which will then be processed and send commands to the servo motor to move following the arduino mega command to the direction of the light source.

Abstract

PT SIM is a leading automotive company in Indonesia which produces two-wheeled vehicles and four-wheeled vehicles. This company requires a lot of raw materials or components to make these products. The components are imported from local and imported suppliers. Especially for imported components, storage is carried out in a warehouse before it is used or produced. PT SIM has used a Warehouse Management System (WMS) to facilitate the control of the inventory, because the amount is very much. Even though we have used an integrated system, but there are no indicators to measure the success of warehouse operations, so it is necessary to do research on indicators of warehouse performance success. The purpose of this study is to design a way to measure the performance of the Warehouse against targets that have been determined using the Key Performance Indicator (KPI). The KPIs element used refers to the activity at the warehouse, ie Receiving, Put away, Storage, Unpacking, Picking and Fulfilment, so it will be determined formulation that can describe a value that can be measured its success. The result of this study indicate that there is a performance report format that can be used to measure the success of warehouse operations at PT SIM.

Abstract

Soybeans will respond differently to shade conditions. One of the obstacles on sheltered land is the lack of sunlight intensity and light energy that can be received by plants. Adaptation to shade conditions can be achieved if plants have the mechanism of capture and use of light efficiently. The purpose of this experiment was to determine the effect of shade on morphological characters, and physiology on Ceneng soybean varieties. The experimental design used was Split Plot Design with the main plot was the level of shade and subplot are soybean varieties . The results showed that the shade treatment affected the growth and yield of soybean by decreasing the percentage of growth in germination, root dry weight, number of root nodules, anthocyanin pigment content, leaf total sugar content, slower flower emergence time, number of flowers at harvest, amount total pods and pod weight, but on the contrary there was no increase in shade-free soybean plants. While the shade treatment also influenced the increase in growth and yield of soybean plants by increasing plant height, number of leaves, number of branches, length, width, leaf area index, chlorophyll a pigment, chlorophyll b and rubberenoid, canopy wet weight, canopy dry weight, moisture content canopy, root water content, decreased number of empty pods and number of filled pods, but vice versa did not occur in shade-free soybean plants.

Abstract

A Boiler is an energy conversion machine that converts water to steam, which occurs due to continuous heating. The steam produced can be used for all equipment that requires steam at a palm oil mill (POM), especially power turbines. In addition, other equipment are sterilizers, pressing station, kernel recovery station and clarification station. The quality and quantity of steam produced must be based on their need, because if it is not achieved it will disrupt the processing in the POM. This study purpose to calculate the quantity of steam needed for palm oil processing in POM. This research was conducted on May 7th until May 12th, 2018. This study used a descriptive method with data gathering techniques by observation, documentation and interview. The result showed that the average steam discharge was 30,523 Kg/hour, while the steam requirement for turbine operation with an actual power of 1,200 Kw was 26,400 Kg and for the palm oil processing was 24,750 Kg/hour. Steam discharge generated by the boiler is over than the mill capacity of 45 Tons/hour, so that the steam discharge generated by the boiler is sufficient to meet the steam need in the POM.
