Abstract

East Java Province is recognized as one of Indonesia’s main producers of the white sugar (plantation white sugar/gula kristal putih). However, The closure of these sugar mills raises an important question about the mills efficiency. The urgency of this study lies in the need to develop a comprehensive literature review that synthesizes existing findings on the production efficiency of East Java's sugar mills. The research was conducted in April 2025, using the literature review  method. The results shows that the efficiency of sugar mills in East Java Province remains below the optimal threshold, both technically and economically. This inefficiency is caused by several factors, including inconsistent sugarcane supply, outdated factory machinery, and socio-economic challenges such as price policy and the low welfare of farmers. Inefficiency has become one of the key reasons behind the closure of several sugar mills in East Java, particularly those owned by PTPN X and PTPN XI.

Abstract

Cocoa is an important commodity that consistently contributes to the structure of the Indonesian economy. The purpose of this study isto analyze the technical efficiency of cocoa based onclones used in PolewaliMandar. This study use Data Envelopment Analysis (DEA) and Tobit Regeression. From the results,some farmers in PolewaliMandar Regency have used the superior clones of Sulawesi 1 and Sulawesi 2 and local clones as the seeds used for side grafting. Separated by 55 farmers planted with Sulawesi 1&2 clones and 54 people using local clones. Both applications have not used input as recommended, such as the use of urea fertilizer, SP-36, KCL, pesticide, manure and labor, still many farmers of respondents who have not gained the optimal results.
