In recent years, inappropriate land use, urban and industrial development along with different pollutions emanating from it gives rise to loss of natural resources and further leads to destructive floods, soil erosion, sedimentation and other various environmental, economic and social damages. Thus, management and planning are essential for the proper utilization, protection and revival of these resources. This study aimed to develop a mathematical-spatial optimum utilization model using FGP – MOLA in watershed including environmental and economic objectives while considering social issues. The results showed that the proposed model can lead to economic growth to 37% and decreasing the environmental damages to 2.4%. Under optimized condition, the area allocated to dry farming lands will decrease about 12% and gardens will increase about 423% and the other land uses remain unchanged too. In addition to, the results demonstrated the usefulness and efficiency of the proposed fuzzy model due to its flexibility and capability to simultaneously provide both optimum values and location of production resources.

Effective Decision

Selecting appropriate and resilient suppliers is an important issue in supply chain management (SCM) literature. Making an effective decision on this issue can decrease external risks and disruptions, purchase costs, and delay times and also guarantees business continuity in the event of disruptions and, consequently, increases company competitiveness and customer satisfaction. This paper aims to provide a model based on identifying and investigating related criteria to evaluate suppliers’ resilience and select the most resilient suppliers in Iran’s electronic industry. To this purpose, the screening technique, the best–worst methodology (BWM), and goal programming (GP) have been applied in the fuzzy environment. The proposed model has been implemented and demonstrated by a case study of the electronic industry, as a real-life example. The results show that agility (0.227), compatibility (0.153), and vulnerability (0.102) are the most important factors for a resilient supplier.

Abstract: The industry has a great influence on the economy of Semarang Regency by becoming the largest contributor to Gross Regional Domestic Product (GRDP). The rapid industrial development from 2011-2017 has an impact on the decrease of agricultural land area, besides that industrial development has implication on land use mismatch of Spatial Plan. This study describes the results of descriptive qualitative analysis with spatial approach from the impact of industrial development on land use change and land use suitability for industry in 2017 against Spatial Plan. The analysis shows that, first, the impact of industrial development on land use change in Semarang regency in 2011-2017 resulted in the amount of agricultural land decreased by 253,32 Ha. The biggest land use change occurred on industrial land use that is 146,10 Ha (28,84%). Second, the use of land for industry in 2017 of 288,05 Ha has been in accordance with the spatial plan is in accordance with the industrial designation area, while the land with an area of 202,02 Ha is used for industries that are not in accordance with the industrial designation area. Keywords: Land Use Change, The Industry, The Suitability of The Spatial Plans Intisari: Industri telah memberikan pengaruh terhadap perekonomian Kabupaten Semarang dengan menjadi penyumbang terbesar pada Produk Domestik Regional Bruto (PDRB). Pesatnya perkembangan industri dari tahun 2011-2017 berdampak pada penurunan luas tanah pertanian, disamping itu perkembangan industri tersebut berimplikasi pada ketidaksesuaian penggunaan tanah tehadap Rencana Tata Ruang Wilayah (RTRW). Kajian ini menjelaskan mengenai hasil analisis secara deskriptif kualitatif dengan pendekatan keruangan dari dampak pembangunan industri terhadap perubahan penggunaan tanah serta kesesuaian penggunaan tanah untuk industri tahun 2017 terhadap RTRW. Hasil analisis menunjukkan bahwa pertama, dampak pembangunan industri terhadap perubahan penggunaan tanah di Kabupaten Semarang tahun 2011-2017 mengakibatkan jumlah luas tanah pertanian mengalami penurunan sebesar 253,32 Ha. Perubahan penggunaan tanah terbesar terjadi pada penggunaan tanah untuk industri yaitu seluas 146,10 Ha (28,84%). Kedua, penggunaan tanah untuk industri tahun 2017 seluas 288,05 Ha telah sesuai dengan RTRW yaitu sesuai dengan kawasan peruntukan industri, sedangkan tanah dengan luas 202,02 Ha digunakan untuk industri yang tidak sesuai dengan kawasan peruntukan industri. Kata Kunci: perubahan penggunaan tanah, industri, kesesuaian RTRW

The Impact

Impact of coastal inundation on ecology and agricultural land use case study in central Java, Indonesia Focusing on the regional scale, this study provides information concerning the existing ecological problems associated with coastal inundation in the northern part of coastal area in Central Java Province, Indonesia. The objectives of this paper are to map the coastal inundation, to investigate the impact of coastal inundation on coastal environment and ecology, and to assess the impact of inundation on agricultural land use. An integration of techniques, namely neighborhood analysis, iteration operation, and superimposed analysis method has been applied to generate the digital map and to analyze the impact of inundation. Fieldwork measurement has been done using cross-profiling in order to observe the impact of inundation on the coastal ecosystem. Based on the scenario of 100 cm and 150 cm of inundation, the affected area is about 15 207.6 Ha and 16 687.31 Ha, respectively. Fishpond, dry farming and paddy field are the most affected agricultural areas due to coastal inundation.
