Although resources are scarce and outputs incorporate the potential to save human lives, efficiency measurement endeavors with data envelopment analysis (DEA) methods are not yet commonplace in the research and practice of non-government organizations (NGO) and states involved in humanitarian logistics. We present a boot-strapped DEA window analysis and Malmquist index application as a methodological state of the art for a multi-input and multi-output efficiency analysis and discuss specific adaptions to typical core challenges in humanitarian logistics. A characteristic feature of humanitarian operations is the fact that a multitude of organizations are involved on at least two levels, national and supra-national, as well as in two sectors, private NGO and government agencies. This is modeled and implemented in an international empirical analysis: First, a comprehensive dataset from the 34 least developed countries in Africa from 2002 to 2015 is applied for the first time in such a DEA Malmquist index efficiency analysis setting regarding the national state actor level. Second, an analysis of different sections in a Rohingya refugee camp in Bangladesh is analyzed based on a bootstrapped DEA with window analysis application for 2017, 2018, and 2019 quarter data regarding the private NGO level of operations in humanitarian logistics.

The fishing ground is identical and closely related to chlorophyll-a abundance in the waters, associated with its fisheries potential. This research has been conducted to determine the concentration and distribution of chlorophyll-a in the seas, especially in the Fisheries Management Area (FMA) 712 encompassing the Java Sea. The analysis used monthly time-series data collected from the satellite imagery over the last 11 years, taken through the ERDDAP website. The mean concentration of chlorophyll-a in the study area was 1.13 mg/l in June 2013. Based on 11 years of data processing, it can be concluded that the highest concentration of chlorophyll-a occurred in the west monsoon season from November to April, where increased rainfall caused the nutrient wash from terrestrial to the open waters. The lowest chlorophyll-a concentration happened in the east monsoon season from April to November, where the dry season arrived. The existence of pelagic fishes in FMA 712, such as Sardinella Lemurs and Sardinella Fimbriata, in waters highly influenced by the chlorophyll-a concentration, while Thunnus Sp. and Exocoetidae Sp. not affected significantly to the existence of chlorophyll-a concentration and its distribution.

Perkembangan produksi perikanan di Pelabuhan Perikanan Nusantara (PPN) Pelabuhan Ratu secara total mengalami peningkatan lebih dari dua kali lipat pada periode 2002 sampai 2013. Peningkatan produksi hanya terjadi pada armada Kapal Motor (KM) dengan armada lebih 5 GT, sedangkan produksi ikan dari Perahu Motor Tempel (PMT) dengan armada kurang dari 5 GT mengalami penurunan tajam. Pada tahun 2013 share produksi ikan dari KM sebesar lebih 95 % sedangkan produksi ikan dari PMT kurang dari 5 %. Kondisi ini mengakibatkan ketidakseimbangan dalam alokasi sumber daya. Tujuan penelitian untuk mengetahui faktor produktivitas total dan indeks ketidakstabilan pada perikanan tangkap. Penelitian dilakukan pada bulan Agustus – Desember 2014 di Pelabuhan Ratu, Jawa Barat. Teknik analisis menggunakan pendekatan Data Envelopment Analysis (DEA) dan Coppock Index Instability (CII). Data yang digunakan adalah data time series statistik PPN Pelabuhan Ratu. Hasil analisis yang diperoleh menunjukkan bahwa sebagian besar armada telah mencapai tingkat efisiesni (nilai efisiensi=1); sedangkan perubahan total faktor produktivitas mengalami fluktuasi yang tajam (berada dikuadran III) pertumbuhan tinggi disertai ketidakpastian yang tinggi, mengindikasikan terjadi ketidakstabilan. Kondisi ini mengindikasikan terjadinya persaingan yang ketat diantara pelaku usaha sehingga menyebabkan terjadinya over-fishing dan over-capasity. Oleh karena itu diperlukan kebijakan untuk dapat mengurangi ketidakstabilan dengan cara rasionalisasi armada tangkap terutama alat tangkap yang sudah tidak efisien dan pengendalian kapal tuna long line. (Total Factor Productivity And Instability Index Of Marine Capture Fisheries: Case in Pelabuhan Ratu, West Java)Fishery production at the Nusantara Fishery Harbour in Pelabuan Ratu increases more than double of production from 2002 to 2013. The increase was only occured for number of marine inboard motor size more than 5 GT, while marine outboard motor size less than 5 GT experienced a sharp decrease. In 2013 the production share of marine inboard motor was more than 95 per cent, while the production share of marine outboard motor was less than 5 per cent. This condition had an impact on imbalaced resource allocation. The applied policy was formulated for fishery management in Pelabuhan Ratu based on information of efficiency, productivity change, and instability index. The analysis was done by using Data Envelopment Analysis (DEA) and Coppock Index Instability (CII) approaches. The result showed that most of big boats (more than 5 GT) have been efficient (efficiency value=1), while total productivity factor fluctuated sharply and indicated instability of production. Coppock Index Instability and growth index showed that most of conditions were on positive growth stage with high level of instability. This conditon caused tight competition among businessmen leading to over fishing and over capacity. A policy is needed to reduce instability by rationalizing capturing boat, especially the infficient ones and to controlling tuna long line vessel.

In today’s increasingly competitive markets, it is essential to be able to determine the position of a company as opposed to its competitors. Today the traditional financial ratios are most widely used to measure corporate performance, but more and more authors begin to criticize their use. It is difficult to use financial ratios as a complex measurement tool. It is crucial to use an appropriate method or tool to measure corporate performance, which can measure the company’s performance in a complex way represented by one indicator. In this study, the Data Envelopment Analysis (DEA) method is used, which is one of the potential tools available. Several researchers have used the DEA method to measure corporate performance. Many authors consider DEA as a useful tool for measuring corporate performance, while others criticize it. The authors analyze the performance of retail food companies in Hungary’s Northern Great Plain region. The companies analyzed were chosen from the region investigated, and they have “food retail grocery store” as their main activity, and they had six cleared annual reports in the period 2012–2017. There was a total of 887 companies in the region examined, and 563 (63.5%) met the conditions. The analysis was made using the time-series data of companies for 2012–2017 based on their financial reports, and the authors dealt with various possibilities for extending DEA, which can support its more accurate use. Based on evaluating the retail food companies’ performance in the Northern Great Plain region, one can state that the efficiency of companies shows a very mixed picture over the years examined. The study suggests solutions to the indicated problem. The findings indicate that the application of extended DEA methods gives better results; that is, one can get better estimates of the efficiency of companies.

Sumber daya ikan pelagis kecil di Laut Jawa merupakan komoditi perikanan yang penting dan bersifat strategis. Sejalan dengan perkembangan pemanfaatannya, tekanan penangkapan yang tinggi dialami oleh hampir seluruh kawasan, terlebih di wilayah tradisionil. Kapasitas penangkapan akhir-akhir ini menjadi isu penting dalam perikanan global, mengingat di berbagai kawasan terjadi kapasitas berlebih dan penurunan stok ikan. Salah satu cara untuk mengetahui status perikanan terkini dilakukan dengan mengukur kapasitas perikanan. Penelitian ini dilakukan pada bulan Mei dan Juli tahun 2007 dengan metode Data Envelopment Analysis. Nilai rata-rata pemanfaatan variabel input (VIU) untuk daya lampu dan bahan bakar menunjukkan nilai di atas 1 (optimum = 1) yang mengindikasikan adanya kelebihan penggunaan variabel sehingga dipandang perlu untuk melakukan pengurangan variabel input. Nilai pemanfaatan kapasitas (CU) lebih besar dari 0,5 hampir mencapai 60% dari 106 kapal contoh. Hal ini menunjukkan bahwa nilai CU kurang dari 1 mendominansi distribusi perolehan nilai CU yang dapat diartikan telah terjadi kelebihan kapasitas pemanfaatan untuk penangkapan pukat cincin mini dengan basis di Pemalang, sehingga perlu upaya pengurangan kapasitas. Small pelagic fish resource in Java sea is an important fishery commodity. Nowadays high fishing pressure is experienced by mostly fishing areas, particularly in traditional zone. Fishing capacity recently becomes important issue in global fishery, because over capacity and fish stock decreasing is occured in various areas. One method to know the fishery status is by measuring fishery capacity, which is categorized as over capacity, under capacity or optimal condition. This study was carried out on May and July 2007. The method applied in this measurement of fishing capacity was DEA method (Data Envelopment Analysis). The average of variable input utilization for light intensity and fuel showed value of more than 1 (optimum = 1), indicating the usage of excess variable that need to reduce the input variable. The value of higher than 0.5 of capacity utilization showed 60% from 106 ships sample. This indicates that the CU value of less than 1 dominated the distribution of capacity utilization value. For mini purse seine based in Pemalang showed over capacity. This means, it needs to reduce the effort of fishing capacity.

Using Data

Fishing capacity is ability of fishery input (boat) used in output production (catch), it measured by using fishing unit or other fishing gear production. In simple way, fishing capacity is an ability of fishing boat (with all aspects) to capture fish. This ability will depend on the fish stock to be captured (seasonally or yearly) and the ability of the fishing gear itself. The aims of this research are to analyze technical efficiency and capacity of capture fishery in between years, of fishing gear and of purse seine. Research location was in the northern water of Gorontalo. Data was analyzed using data envelopment analysis (DEA). The development of capture fishery in 20 years since 1986 - 2005 of the northern water of Gorontalo showed that 1995, 2003 and 2005 are the most efficient years compared to other years, therefore, these years can be used as a basic of allocating fishing effort and catch. The most efficient fishing gear was purse seine and line, whereas gill net is an inefficient fishing gear. For purse seine, there are 11 boats that have efficiency value of 1. In order to reach efficiency level of each purse seine, it needs to decrease the number of input such as reducing 27.97 percent of boat, reducing the length of fishing duration to 29.49 percent,reducing the length of fishing trip / tonnage month to 26.87 percent and reducing fishing operation cost to 15.67 percent.

For decades, the problems of excess capacity and overfishing have been the subject of considerable attentions, sincethey are the primary reasons for the depletion of fish stocks, reduction of the profitability and economic performanceof the fishery sectors at the national and international levels. As a result, estimations of technical efficiency,harvesting capacity, and capacity utilization has become an increasingly important practice in the fishery, since theyprovide useful information about the optimum allocation of inputs and outputs, and guide policy formulation tocombat biological and economic losses. Based on the Johansen (1968) definition of capacity we have examined thetechnical efficiency, capacity and capacity utilization of the marine fishery sectors of the India’s 9 marine states and4 union territories using an output oriented data envelopment analysis approach. The result of the study shows thatmajority of the states/union territories have been inefficient and have the capacity to harvest considerably more thanwhat they have actually been harvesting by using the existing resources in an efficient configuration and showed howserious the problem of excess capacity is in the India’s marine fishery.

Degradation of marine ecosystems through, e.g., eutrophication and climate change is a concern for sustainable fishery management worldwide, but studies on associated impacts on fish populations are rare. This study examines the effects of eutrophying nutrient loads on the economic value of perch populations along the Swedish east coast by estimating the effects of nutrient loads on the population of perch and, then, simulates the harvest value of future perch population under the changes in nutrient loads. A modified Gordon-Schaefer logistic growth model was used for econometric estimation of perch populations based on annual time series data for the period of 1970-2014. Regression analysis using the fully modified ordinary least square (FMOLS) estimator revealed that phosphorus loads had significant effects on the perch population. A 40% decrease in phosphorus loads, as suggested by the international HELCOM agreement, could increase the steady state perch population by 50%. Simple calculations showed that this could increase the total discounted recreational and commercial harvest value of the perch by 30% over a 30 year period.
