Facility Location Modeling in Multi-Echelon Distribution System: a Case Study of Indonesian Liquefied Petroleum Gas Supply Chain

-This paper presents model of Indonesian LPG supply chain by opening new facilities (new echelon) taking into account the current facilities. The objective is to investigate the relation between distribution costs such as transportation, inventory cost and facility location in Indonesian multi-echelon LPG supply chain. Fixed-charged capacitated facility location problem is used to determine the optimal solution of the proposed model. In the sensitivity analysis, it is reported that the trade-offs between facility locations and distribution costs are exist. Results report that as the number of facility increases, total transportation and inventory cost also increase

Location-allocation modelling for Indonesian multi-echelon LPG supply chain

This research is to design the Indonesian LPG distribution system through Location-allocation modelling taking into account the existing facilities. Location-allocation model is developed in fixed charge capacitated location-allocation problem considering transportation and inventory decisions. Multi echelon LPG distribution system is considered to be modelled from regional warehouse to agents. The objective of this research is to determine the candidate locations of regional warehouses and feeder filling stations optimally and evaluate the implications of the future changes as sensitivity analysis. The optimal result found that the location-allocation model for the proposed distribution system results a better outputs on associated distribution costs than in the existing distribution system. The global optimal shows that in the proposed distribution model, total distribution cost from echelon 1 to 4 is lower than in the existing distribution system. Meanwhile, the service level, which is represented by the percentage of LPG shortage, is also lower, about 28 per cent lower than the existing distribution system. Four scenarios of different facility location numbers such as 9, 12, 17 and 18 FFSs are applied in the model. It is found that there is a trade-offs between location adjustment, location-allocation costs and service level. Comparing to the optimal results, less number of FFS decreases transportation and inventory cost that leads the decrease of total distribution cost. It is also observed that service level which is represented by the number of LPG shortages in the distribution system elevates as the number of FFS decreases. Furthermore, the implication of increasing demand to the proposed model reveals different results. It is found that the increasing demand which is projected by Pertamina for the next four years impact significantly on the location-allocation decisions. It is reported that the projected potential FFSs locations and LPG allocation changes as LPG demand increase. As consequences, the associated distribution costs as fixed cost, inventory and transportation cost also increase. The same phenomenon also occurs in the investigation between service level applied in the echelon 4, associated location-allocation costs and LPG shortage in the distribution system. This research also considers direct and indirect distribution system between echelon 2, 3 and 4, in which FFS is not only allowed to supply LPG to FS, but also to agents. The model of this research could contribute for further research in location-allocation problem in term of the hierarchical distribution system and the integration of other logistics aspects into the model

Muslim and non-muslim perceptions on Halal Meat Logistics (HML)

The study explores customer preferences of willingness to pay halal meat products based on logistics activities for Indonesian consumers in muslim and non-muslim areas. Two different Indonesian places were chosen to explore and compare the difference preferences about halal meat products. This paper investigates the factors influencing muslim consumers to pay halal meat products especially in term of logistics activity factors. The respondents of East Java and Bali provinces are collected to be compared to explore consumers\u27 preferences in purchasing halal meat products in term logistics activities. Statistics descriptive is used to answer the research question using Cut off Point (COP) or average ration to figure out the distribution data of respondents in two different areas. Two variables considered in this study are halal logistic performance and customer\u27s satisfaction

Location-Allocation Modeling for Indonesian LPG Distribution

This study investigates the current distribution networks of Liquefied Petroleum Gas (LPG) for location-allocation modeling. The aim of the study is to model inventory and transportation decisions into location-allocation problem in a Multi-Echelon Distribution Channel

Program Gerakan Masyarakat Hidup Sehat (Germas) dan Deteksi Dini Penyakit Tidak Menular (PTM)

Effective prevention and control of PTM requires effective interaction between health care facilities from the primary level to the referral level, which includes promotive, curative, palliative and rehabilitative prevention of PTM cases. All first-level health service facilities must be staged in stages to be able to manage PTM in an integrated manner with a focus on families. The aim of the activity is to increase awareness, willingness and the ability of people to behave in healthy living and early detection of non-communicable diseases. Methods lectures, questions and answers, blood pressure measurement, blood sugar testing, gout, measurement of body weight, height, fruit eating movements and stretching exercises. Target audience Age ≥ 15 years and over, obesity has a history of suffering from hypertension and DM. The number of participants is 56. The results of this community service showed that out of 56 people, 25% had a waist circumference >90cm, identified 66% had hypertension, 39.3% identified symptoms of diabetes mellitus until they were identified as having diabetes mellitus. Conclusion not all people willing to do a health check. It is recommended to the health department so that the results of community service activities can be followed up by the Health Service through the nearest Puskesmas so that people who are detected as having non-communicable diseases (PTM) can be immediately dealt with

Scheduling the optimal LPG distribution using periodic vehicle routing problem: a case study in Indonesian LPG distribution

One of the biggest problems faced in distributing products is determining the scheduling of product delivery and delivery routing. Suboptimal delivery schedule and delivery routing of the products will impact seriously to distribution costs. Periodic Vehicle Routing Problem (PVRP) is one of the methods can be used to solve the distribution schedule and routing delivery. This paper studies the application of PVRP method with cluster first second round (CFSR) approach in distribution of Liquefied Petroleum gas (LPG) in Indonesia. The results show that the region of distribution should be clustered into two clusters. Three delivery frequencies of 1 and 2 clusters, gives an optimal solution. The results of delivery routing which are obtained from Lingo software using Ant Colony algorithm indicate that there is a decrease of distances, about 347.19 km from the previous distribution system and it reduces about 25% of the current distribution costs per week

Bantuan Kemanusiaan Korban Bencana Alam Banjir Bandang dan Tanah Longsor di Masamba, Kabupaten Luwu Timur Sulawesi Selatan: Humanitarian Assistance for Victims of Natural Disasters Flash Floods and Landslides in Masamba, East Luwu Regency, South Sulawesi

Monday, July 13th, 2020, Flash floods and landslides have hit the Masamba area, East Luwu Regency, South Sulawesi. The large number of victims and urgent needs and in order to ease the burden on the victims, the Academic Community of the Poltekkes Kemenkes Palu initiated a community service program in Masamba Regency.
