Abstract

Palm oil was first introduced in Indonesia by the Dutch government in 1848, at that time there were 4 oil palm seedlings planted at Bogor Botanical Garden (Botanical Garden) in Bogor, two from Bourbon (Mauritius) and two from the Hortus Botanicus, Amsterdam ( Netherlands). Currently the development of oil palm cultivation is increasing with an area of 2017 covering 11.5 million hectares and the production of palm oil (CPO) has reached ± 30 million tons in 2018. The main objective of this research is to find out the influence of the increase of capacity achievement, availability of raw materials and the achievement of oil and palm kernel oil to the performance of oil palm factory, especially the cost of processing so that it can give added value to the company. Based on the result of the research, it is known that the capacity of X1 is negative but not significant. This is in accordance with the hypothesis, the availability of raw material (X2) is negative but not significant and the yield of rendement (X3) is negative but not significant this is in accordance with the hypothesis and capacity though, the availability of raw materials and yields of yields together have a significant effect on the cost of processing. On the basis of this, then the management should increase attention to the capacity of the process, the availability of raw materials and the achievement of rendemen to minimize the basic price.

Abstract

The average CSR development in PTPN-IV Adolina Business Unit has increased every year with a larger budget and realization. This study aims to determine the success factors of CSR which have a significant effect on the sustainability of oil palm companies, the elements that form a sustainable palm oil industry, the effect of good CSR implementation on the sustainability of the palm oil industry, building a CSR-based strategic management model towards the palm oil industry. sustainable. This research method uses descriptive quantitative research methods with a total sample of 102 people. The types of data used are primary data and secondary data. Primary data were collected through a questionnaire measured through a Likert scale and secondary data through documentation studies. The data was processed with SPSS 20.0 for Windows software. Hypothesis testing uses Multiple Regression Analysis. Research to see the effect of corporate commitment, operational standard CSR internalization policies, involving the community on the implementation of CSR in the oil palm sector of PTPN IV Kebun Adolina. The results of this study concluded that company commitment, CSR internalization policies in operational standards and involving local communities, have a significant positive effect on CSR implementation, where the most significant positive effect is first involving local communities, then CSR internalization policies in operational standards and then corporate commitment companies towards the implementation of CSR in the oil palm sector at PTPN IV Kebun Adolina.

Abstract

Modern management of smallholder oil palm plantations is very much needed to enable smallholder oil palm plantations to follow the progress of management of large oil palm plantations, both state-owned and privately owned. This study aims to determine how production factors influence production and to determine the technical efficiency of smallholder oil palm plantations. The location of the study was determined purposively based on the consideration of the existence of smallholder oil palm plantations in the area. The sample was determined by quota sampling of 150 samples from two villages, namely Buntu Bayu Village and Buntu Turunan Village, each with 75 samples. The analysis involves applying the Multiple Non-Linear Regression Test (Rank Test) alongside Data Envelopment Analysis, focusing on managing smallholder oil palm plantations throughout 2023. The study results show that, partially, the production of smallholder oil palm plantations is significantly positively influenced by each production factor. Conversely, the output of smallholder oil palm plantations is notably affected by various production factors, including land, labor, fertilizer, and pesticides. Most (78.00%) smallholder oil palm plantations are technically inefficient, with an average technical efficiency value of 0.9755. To achieve a technically efficient production process, smallholder plantation farmers must reduce inputs, namely 2.5416% of the land, 4.0501% of labor, 5.5449% of fertilizer, and 3.1165% of pesticides.

Abstract

This study was conducted to analyse the economic efficiency of smallholder oil palm plantations and the socioeconomic factors that affect them. The study area was purposively selected because it is the sub-district with the largest area of smallholder oil palm plantations in Padang Lawas Regency, with the largest area of smallholder oil palm plantations on the West Coast of North Sumatra Province. The study sample was determined using quota sampling, with 150 samples drawn from Aek Lancat Village and Pagaran Mompang Village, each with 75 samples. Data analysis methods used: Data Envelopment Analysis and Censored Tobit Regression Analysis for smallholder oil palm plantation management data for 2023. The results showed that the majority (85.33%) of smallholder oil palm plantations were not economically efficient, with an average economic efficiency value of 0.8789. Factors such as gender, farming experience, family size, type of seed used, distance from the farmer's residence to the input market, and experience in applying organic fertiliser significantly affected the economic efficiency of smallholder oil palm plantations. Meanwhile, socioeconomic factors such as age, education, the number of productive oil palm plants cultivated, access to credit, experience in participating in farmer organisations, and farmers' experience in using information and technology facilities related to farming management have no significant effect on the economic efficiency of smallholder oil palm plantations.

Abstract

The technical efficiency of smallholder oil palm plantations is a reflection of the farmers' ability to coordinate the use of inputs to obtain the desired output. This study aims to determine the value of technical efficiency and factors that influence the technical efficiency of smallholder oil palm plantations. The research area was determined purposively on the grounds that it is a sub-district area that has the largest area of smallholder oil palm plantations in Asahan Regency as the regency area that has the largest area of oil palm plantations in North Sumatra Province. The research sample was determined by quota sampling of 150 samples originating from two villages, namely Gonting Malaha Village and Padang Pulau Village, each with 75 samples. The data analysis method used Data Envelopment Analysis and Censored Tobit Regression Analysis for data on the management of smallholder oil palm plantations during 2023. From the results of the study, it was found that the majority (81.33%) of smallholder oil palm plantations were not technically efficient, with an average technical efficiency value of 0.9782. Factors that significantly influence technical efficiency are gender, age, farming experience, number of productive crops cultivated, distance from the farmer's residence to the input market, farmer experience applying organic fertilizer, experience participating in farmer organizations, and experience using information and technology facilities related to farm management. Meanwhile, factors such as education level, family size, type of seed used, and access to credit by farmers have no significant effect on technical efficiency.
