Abstract

As a maritime country, ports play an important role in economic development in Indonesia. Throughput is an important factor affecting Port Profits. This prediction is needed in an effort to find out the company's prospects, help estimate the long-term profitability of representatives, predict earnings, and estimate risk in investment. In this research, forecasting data throughput will be carried out, such as container traffic, number of ships, export traffics, goods traffic, animal flow and passenger traffic for the next year using Time Series-Adaptive Neuro Fuzzy Inference System (TS-ANFIS) as an input parameter in the decision support system. Before predicting the benefits of the port using the ANFIS method, principal component analysis (PCA) was applied to reduce parameters that did not sufficiently affect the profits of the port. The data used are time series data from 2009 to 2018. From the system built it is expected to be able to provide good results in predicting the value of port throughput using TS-ANFIS and to predict profit values using the ANFIS method. The best results from profit prediction using ANFIS obtained R2 of 0.947, RMSE of 28524582.39, MAPE of 14.74% and MAAPE of 0.145. From the prediction results, it can be used as a reference for company projections in investing, managing cash flow, managing assets and global bonds.

Abstract

PT Y is a subsidiary of Y Group which specializes in producing speakers for local and international markets. At present PT Y's orders have not met the expected performance targets. Fulfillment of production orders reached 97.55% of the target of 100%. This is one of the concerns of Y Group that PT Y need to improve themselves because it can result in companies becoming less competitive than competitors. Based on preliminary observations, there was indications of waste, namely defects, downtime, and process delays. The lean tool used for further waste analysis is Lean Assessment Matrix (LAM). The results of the research show that the waste which gives the most significant influences are transportation, waiting and inventory. The root causes of problems between work stations are not ergonomic, do not have preventative maintenance schedules, there are no standards for handling defective products, the layout of the room is not in the direction of material, the carrying capacity of hand trucks is small, and the Outgoing Quantity Check (OQC) processes are not included in the company’s time standards. The proposed improvement recommendations include conducting training to improve product repair skills, relayout of production plant, and making a preventative machine maintenance schedule.

Abstract

For the past 15 years, radio and music industry trend is decreasing. One of the causes is “disruption” from Radio Internet Pureplay such as Spotify, Joox, etc. Svara came with “Beyond Disruption” concept that can be saved radio and music industry by starting Radio Digital Transformation. Nowadays, the growth of IT Start-Up Company keeps increasing. which also followed by the increased number of skilled IT workers. The turnover rate over the IT Company also increases. Most of the employees stayed for a short period then moved to another company. This high turnover rate causes decrease in productivity that affected the revenue of the company since low level of employee engagement. In this paper, PT Svara Inovasi Indonesia will be studied and improved employee engagement. The factors of employee engagement level are measured through the data collected by questionnaire. The main objective of the study was to measuring and improving the employee engagement level on PT Svara Innovasi Indonesia. To measure employee engagement with suggestive improvements, the study uses 3 models; Gallup Q12, Aon-Hewitt Employee Engagement Driver, and Deloitte Simply Irresistible Organization model. The result is identified that “stay” component from employee engagement level is low. This caused by low level of recognition, rewards, and work-life balance. This could be improved to increase engagement level, productivity and reducing turnover.

Abstract

PT. Mortars is an instant cement producer with many product variants. Some problems that PT. Mortars encountered are uncertainty of demand, limitation on production capacity, and inventory capacity, which caused product shortages and high inventory costs. The production scheduling process is produced manually so it requires a long time, relying on the ability and experience of the production planner which is vulnerable to mistakes. Therefore, new methods and tools are needed for inventory control and production scheduling to make sure goods are delivered to customer just in time while maintaining operational efficiency. Periodic review system (R,S) and (R, s, S) methods are proposed in this study to improve inventory parameters and reorder systems that have an impact on service levels and inventory costs. The tools are designed using Microsoft Excel software with solver add-ins functions and linear programming approaches to generate optimal production schedule decisions automatically. In order to determine the level of service and inventory costs generated by each method, a simulation is conducted by using the tools that have been made. The simulation of the existing method produces a service level of 98,64% and a total inventory cost of Rp. 1.167.160.494. The periodic review system (R, S) method resulted in increasing service level of 0,96% and lower inventory cost of Rp. 15.130.801 while the periodic review system (R, s, S) method resulted in increasing service level of 1,29% and a lower inventory cost of Rp. 448.653 compared to the existing method. The periodic review system (R, S) method produces the lowest inventory costs while the method (R, s, S) produces the highest service level compared to other methods.

Abstract

Green supply chain management (GSCM) is one of the strategies to overcome environmental problems caused by industrial activities and pressure from stakeholders such as the government and customers.The concept of green supply chain is a multidisciplinary issue that emerges essentially from building environment-friendly management practices in the context of supply chains. Nowadays manufacturing moves to Asia, awareness of green operations or sustainability has become important but relevant studies in Asian countries are not many especially in the Southeast Asia region .Prior studiesabout effects of GSCM on firm performance suggested for more in-depth research on the effect of each GSCM practices on company performance because GSCM's scope is quite extensive. Furthermore, several studies that examine the relationships between GSCM practices and organizational performance, there is a dearth of studies that have considered these relationships within the context of organizational or business strategy. Most studies have examined the outcomes of GSCM within the context of tangible measures such as environmental, operational, and economic performance. Consequently, research on intangible outcomes of GSCM practices is limited. Thus, the need examines the deployment of GSCMand analyzes their impact on environmental, economic and intangible performance.

Abstract

There’s emerging discussion about creative financing and diversification to close the funding gap of a massive development plan, with future flow securitization is one of the candidates. Since the first transaction undertaken in the late 1980’s, future flow securitization still rarely used in Indonesia. Currently, such type of instrument was coming from the state-owned enterprise notably the state toll road enterprise securitized their future toll-road revenue flow. The Government of Indonesia could use future flow securitization as part of financing diversification, with rationalities of lowering the cost of capital through secured financing, risk-sharing to the private sector, and earmarking certain revenue for particular spending. Badan Layanan Umum/BLU (public service agency) could be the agent to conduct such financing, enabled by its characteristics of public service function mixed with corporate-like governance and also its nature of revenue center agency. The government would still be in complete control since BLU is within government arms’ length and its financial management is not separated from the general budget. This study derives the potential use of future flow securitization through BLU. From the central government financial report, we found – on an aggregate basis – that there is a proper capacity of BLU’s revenue to be securitized. This paper using qualitative method to construct a securitization-fit framework comprised of model, requirements, criteria along with features of the binding arrangement, required organizational settings, compartmentalization, and tranching.

Abstract

In this study the equipment lease contract, where two players, the lessor, lease the equipment to the user (lessee), if the equipment fails to exceed the tolerance agreed by both players during the lease period and needs to be repaired, it is considered detrimental to the lessee, because it results in a loss of potential revenue will be received from leased equipment. Therefore, the total income of the lessor in the lease contract may incur penalty costs as a consequence of the lessor for failure to maintain maintenance performance. We use Nash's game theory formulation to find a win-win solution between players where it is an equilibrium point for lessor and lessee. The results of this study are, when Lessee decides to maximize profits, which is the total potential profit gained by the lessee using leased equipment, and the lessor also decides to maximize their profits derived from the leased equipment by considering penalty cost as a cooperatively determined variable. The selected scenario is the percentage of the minimum penalty cost with the maximum level of equipment used.
