Abstract

This study aims to empirically measure and analyse the production and marketing efficiency of the patchouli oil industry in Aceh, Indonesia. The study uses primary data collected from 120 patchouli farmers and analysed using the Data Envelopment Analysis (DEA) approach. The results showed that, on average, the patchouli oil production and marketing efficiency levels were in the moderate-eficient and the low-efficient categories, respectively. The patchouli farmers have great opportunities to improve their production and marketing efficiency by optimising the use of proper inputs’ combinations and agricultural intensification technologies.

Abstract

Today, determining the priorities of spatial and economic development of Russian cities is a key strategic goal in the Russian Federation. Acting as points of growth and connecting elements of economic processes, cities form a common framework of settlement. Existing urban disparities distort the territorial space, demonstrate its insufficient integrity, which reduces the quality of life of the population and poses a threat to socio-political stability.

The purpose of the study is to determine the features of the interconnectedness of cities in the Russian Far East using the Moran index. The estimation method is based on the calculation of the global and local Moran indices to determine the effects of connectivity of territories by indicators: “population size”, “population density”, “volume of products shipped per capita”, “average monthly salary”. The information base was the data of the Federal State Statistics Service, the distance calculation was carried out according to the data of the automobile portal. The object of the study is the cities of the Far Eastern Federal District, with a population of more than 100 thousand people in 2017.  The calculations made it possible to determine the type (direct and reverse) and the strength of interterritorial relations according to the considered parameters. According to the indicators “population size”, “population density”, there is a negative autocorrelation, according to the indicators “volume of products shipped per capita”,” average monthly salary”, there is a positive autocorrelation. The calculations revealed the presence of polarization in the territory of the Russian Far East. The strongest relationships are between Vladivostok (LISA -0,314), Khabarovsk (LISA -0,026) in terms of population; Artem (LISA -0,165) Vladivostok (LISA -0,084) – population density; Artem (LISA 0.116), Komsomolsk-on-Amur (LISA -0,036) – the volume of products shipped per capita; Ussuriysk (LISA 0.081), Artem (LISA 0.092) – average monthly wages.

The scientific significance of the conducted research consists in the development of theoretical and methodological provisions in relation to the assessment of spatial interterritorial relations. In the future, work will continue in terms of studying autocorrelation in dynamics, expanding the analyzed indicators and identifying spatial and temporal shifts, for a deeper understanding of the patterns of spatial development of cities.

Abstract

South Sumatra Province is known as Indonesia’s largest natural rubber-producing center. In the last few decades, South Sumatra has faced climate change issues marked by increased variability of maximum temperature, mean temperature, minimum temperature, and rainfall. On the other hand, smallholder rubber plantations are considered to be particularly vulnerable to climate change. Therefore, the goal of this study was to identify the climatic factors that affect the productivity of smallholder rubber plantations in South Sumatra. The data was gathered from the Indonesian Central Bureau of Statistics and the Indonesian Agency for Meteorology, Climatology, and Geophysics from January 2006 to December 2019. A quadratic regression model was used to analyze the data. The results showed that maximum temperature, mean temperature, minimum temperature, and rainfall affect the productivity of smallholder rubber plantations. Maximum temperature and rainfall indicate a pattern that is increasing to the optimum point of 32.29 °C and 281.40 mm respectively and after that, it will slow down. The mean temperature and minimum temperature show a pattern that is decreasing to the optimum point of 26.84 °C and 22.14 °C respectively and after that, it will slow down.
