Abstract

  Achieving the economic efficiency of the oil palm business is largely determined by the scale of the cultivation of the oil palm farms. This study aimed to analyze the performance of smallholder palm oil farming and its supply chains. This research used survey method. The research location was at the community oil palm plantation center in Tulang Bawang Regency, in Penawartama District and Gedung Aji Baru. The sample of oil palm farmers amounted to 74 respondents of farmers and the trader agents who involved in the supply chain. Analysis of farm performance used indicators of productivity, prices, farm cost efficiency, and income. Business scale can be divided into three classifications, as high, medium, and low business scale. Analysis of different tests of productivity, income and business scale using Least Squares Differences (LSD). Supply chains analysis used the S-C-P (Structure, Conduct, and Performance) model analysis. The results showed that the performance of independent smallholders of oil palm farming differed in their level of productivity and income on the scale of farming land, between small, medium and large landholders. The optimum of oil palm land makes a very significant difference in the level of palm oil farmers’ income received by smallholders on a large scale of land. While not significantly different between the scale of a narrow and medium scale. Oil palm fruit bunches (fresh fruit bunches FFB) supply chains involve marketing institutions namely lapak and agents as an extension of the palm oil mill. The flow of the independent farmer in FFB trading system involved many intermediaries as a market institution, that is, from the farmer-stall agent-the company raises the risk of low prices at the farm level. The assessment of FFB marketing performance illustrates the condition of price uncertainty with a reflection of the high FFB price range at the farm level. This puts the marketing performance of FFB not in favor of independent oil palm farmers.

Abstract

Corn shelling tools have developed in Indonesia ranging from very simple corn shellers to mechanical corn shellers. However, the maize sheller with a medium-scale capacity has not been well developed. The research objective was to design and analyze the performance of a medium-capacity portable corn sheller machine to meet the maize harvest processing process, which can increase productivity, the quality of maize shelled with medium-scale capacity and also develop a new shelling tool design. This research was conducted in 3 stages, namely field observation, design, and machine performance. The results showed a corn sheller machine with a 0.5 hp electric motor. The results of the work show that the speed of the shelling process is very influential on the results of the shelling. The higher the speed of the shelling process, which is 2400 rpm, the better or no leftover corn is shredded.

Abstract

Utilization of biogas by-products is expected to increase the beneficial aspects of the existence of a biogas reactor as a source of input for small-scale agriculture, despite the main function as a renewable energy supply. In this study, formulation of solid fertilizer from biogas solid waste and evaluation of formulation yields have been done. Solid (sludge) waste from the biogas reactor were separated and mixed with another biomass for further processing into fertilizer or nutrients for plants. Two formulations have been made (3 kg each) with treatments of one week fermentation with once back stirring (P1) and two weeks fermentation with twice back stirring (P2) aimed to identify the difference between the two samples based on the quality of solid fertilizers produced. The evaluation tests were pH, water content, C-organic, C/N ratio, by-products substance, NPK total, Fe total, and Zn total. The data were analyzed statistically using independent t-test Parametric Statistic for normally distributed and/or homogeny data and also Mann Whitney Non-Parametric Statistic for the opposite. The test results of the fertilizer formula showed a pH value of around 6-7 with water content value of 52-67%. C-Organic value resulted was 25.89±3.10 (P1) and 21.35±1.99 (P2). The resulting C/N ratio was 25,89±3.10 (P1) and 21.35±1.99 (P2). By-products substances, NPK total, Fe total, and Zn total parameter were in accordance with the quality standard of solid fertilizer. Further development efforts are needed to adjust the moisture content of the developed formulation. Moisture content was estimated to affect shelf life, in relation to the number of live microbes as a quality control.

Abstract

This study aims to analyze the factors that influenced the production of roses and the level of technical, allocative, and economic efficiencies of rose farming in Central Java along with the factors that influenced them. This study employed Stochastic Frontier Analysis (SFA) and dual cost reduction methods. The findings of this study indicate that only three variables had a significant effect on rose production in Central Java, namely land area, number of plants, and chemical fertilizers. Furthermore, in terms of the level of efficiency, rose farming in Central Java had been said to be technically efficient but had not been considered to be efficient in terms of its allocation and economic factors with an average score of technical, allocative, and economic efficiencies of 0.82, 0.33, and 0.28. Socio-economic factors that significantly affected technical inefficiency were the source of seeds, business assistance, and partnership. Meanwhile, the variables that had a significant effect on allocative inefficiency and economic inefficiency were the proportion of self-financing sources, farmers group membership, and partnerships. Keywords: dual cost, efficiency, stochastic frontier, rose farming

Abstract

The mini factory operated by PT Aneka Laba Jaya Utama (AULAJU) is the only mini factory in Lampung Province.  However, the current business activities seem to be "running in place" and even chocolate production has stopped for almost a year.  Therefore, a financial feasibility study was carried out as a basis for planning for the development of PT AULAJU's chocolate production business.  The research was conducted at the Perseroda PT AULJU, Pesawaran Regency, Lampung Province.  The analysis used in this study is testing the investment criteria, that are Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit Cost Ratio (Net B/C), Gross Benefit Cost Ratio (Gross B/C), dan payback period (PP).  The business development strategy was analyzed using SWOT analysis.  The results of the discussion show that PT. AULAJU was declared eligible to be run and developed because NPV=27 billion >0 (positive), IRR=86%>BRI Bank interest rate 12%, Net B/C=1,01>1, Gross B/C=2,01>1, and PP=1,44 (Payback Period< maximum time/economic life of investment (10 years).  On the other side, PT AULAJU must make improvements in the context of developing its business. The three main priority strategies are 1) Repair and rejuvenation of machinery and factory equipment that have been damaged or are no longer used, 2) Optimizing the management of BPOM and Halal production permits, etc., 3) Improving the management of BUMD management.

Abstract

South Lampung Regency is the center of corn production in Lampung Province. However, the low productivity of corn  due to the suboptimal allocation of production factors has affected the efficiency of corn farming production. This research aims to analyze the level of technical, allocative, and economical efficiency corn farming in South Lampung Regency. Two subdistricts in South Lampung Regency—Penengahan and Ketapang—that are major corn production hubs were used for data collection. The data collected in this study are primary and secondary. Primary data was obtained using a survey method, namely by directly interviewing corn farmers using a list of questions (a questionnaire) that has been provided. Secondary data were obtained from institutions or agencies related to this research. A simple random sampling method was used to choose up to 71 maize producers for the sample size. The Stochastic Frontier Cobb-Douglas production function is used in data analysis and is processed by the Frontier 4.1 application. The results show that corn farming was technically efficient but not allocatively or economically efficient.. The use of inputs appropriately and efficiently will reduce the use of excessive inputs, which can then be allocated to the purchase of other inputs that are less used, with the aim of achieving allocative and economic efficiency.

Abstract

The demand for local soybean commodities is very low compared to imported soybeans, which affects the decline in soybean planting area, and farmers are also less willing to farm soybeans because they are less profitable. Government policies related to soybean self-sufficiency are widely carried out, but imported soybean commodities still have stronger competitiveness. This study aims to analyze the competitiveness and government policies on soybean farming in Tamalatea District, Jeneponto Regency. This study used a survey method. Data collection techniques are observation and interviews. The sampling technique using purposive sampling is to choose soybean farmers who are more productive in their farming, so that the number of samples obtained is 48 farmers. The data analysis technique is quantitative descriptive analysis with the Policy Matrix Analysis method. The results of this study indicate that soybean farming has strong competitiveness, because it has a Private Cost Ratio value of 0.2077 and a Domestic Resource Cost Ratio of 0.1628, with a private profit of Rp 5,752,342.42 per hectare and social profit of Rp 7,682,461.16 per hectare. The input policy on soybean farming resulted in values including: input transfer (IT) of -184,240.32, transfer factor (TF) of Rp 14,365.87, and nominal protection coeficient input (NPCI) of 0.61104. Meanwhile, the output policy resulted in an output transfer (OT) value of Rp -2,099,993.19 and a nominal protection coefficient input (NPCO) of 0.7824. Input-output policies have values including: effectivity policy coeficient (EPC) of 0.7912, subsidy ratio for producer (SRP) of -0.20001, profitability coeficient (PC) of 0.7488, and net transfer (NT) of -1,930,118.73. Government policies that are protective of tradable inputs have a positive impact on soybean farming, so farmers pay lower prices than they should. Government protection policies against tradable output have not been effective, so soybean farmers get output prices that are lower than the price they should. Government policy on tradable inputs simultaneously has not been effective in protecting soybean farming, so it has not been able to provide incentives for increased production.
