Abstract

Oil palm plantations have a strategic role as a contributor to the country's foreign exchange and as a provider of employment opportunities for people in Indonesia. Palm oil production in Indonesia is still dominated by large private plantations, but smallholder plantations are increasingly playing an important role in palm oil production. However, the problem is that the production of crude palm oil (CPO) by smallholder plantations has large variations, and is below plantation standards. This study aims to determine the factors that influence smallholder oil palm production in Riau Province. The data collected is secondary data based on the results of the 2013 agricultural census by the Central Statistics Agency (BPS). The number of samples as many as 4,038 farmers, spread across the Riau Province. The method of determining the research location was chosen purposively, namely Riau Province as the research area with the consideration that this area is the largest palm oil producing center in Indonesia. The analytical method used to determine the factors that affect oil palm production is the Cobb Dauglash production function model which is estimated by the OLS (Ordinary least square) method. The results showed that the factors that influenced the production of smallholder palm oil in Riau Province were the number of plants, plant age, urea fertilizer, SP36 fertilizer, NPK fertilizer, organic fertilizer, number of workers,  members of the cooperative and  partnership participants.

Abstract

Increasing food production, which is currently difficult to do on productive land with an extensification pattern due to limited land availability, causes the exploitation of wetlands with the category of lebak land (marginal land) to be an option for expanding food crops to increase food production in South Sumatra which has a lot of wetlands.   Technological engineering is an option in overcoming the constraints of processing lebak land, especially in the use of agricultural tools and machinery which are still low in interest and adoption rates among farmers.  This study aims to; (1) formulate strategies so that farmers are interested in cultivating lebak land into productive land, (2) formulate farmer adaptation strategies in cultivating lebak land by applying relevant technology.  The survey method was used in this study with two layers of samples (farmers who used Alsintan and farmers who worked on the land manually), as many as 50 respondents in each layer (a total of 100 respondents) were taken using a simple disproportionate random method. Primary and secondary data obtained, processed to calculate income, tested for differences using paired sample t tests, the results of which became the basis for strategies to increase farmers' interest.  Formulation of adaptation strategies using the SWOT method with the results of the study: (1) farmers who apply mechanization technology in cultivating rice in lebak land can do their farming with IP 200, incur lower production costs, and higher production and income than farmers who cultivate it manually; (2) The use of mechanization technology is still not efficient in the use of seeds, fertilizers, pesticides, so it must be optimized, (3) The adaptation strategy that must be carried out by farmers is an aggressive strategy because it is in quadrant I, which shows that rice farming in lebak land is in a strong position and has great opportunities to do.  This strategy is the main strategy because the strength factors (S) and opportunities (O) owned by farmers in cultivating rice on lebak land have a value greater than the weakness factors (W) and threats (T) that will be encountered.

Abstract

Coffee agribusiness in Indonesia has grown rapidly in the last 5 years. This commodity has great potential to make a significant contribution to the post-pandemic national economic recovery (PEN) program. The results of previous studies showed that most of the coffee beans from farmers (56%) were sold in the form of dry beans (raw material), or in bulk. Meanwhile, the rapid progress of the tourism and creative economy sectors as well as the development of consumer preferences in the food and beverage business have been able to elevate premium coffee (picked red) into a potential new market for farmers. However, limited market access and supply chain systems as well as yield handling technology mean that this potential is only enjoyed by a small number of farmers. This study aims to: identify the coffee supply chain system from farmers to consumers (exporters/coffee processing industries) from West Lampung production centers to Bandar Lampung City. Based on the identification of the coffee bean supply chain system, there are eight streams of the coffee bean supply chain and several actors who are directly involved, namely farmers, collector traders, wholesalers, farmer groups, federate farmer groups, joint business groups, and consumers (exporters and industry). The results of calculations and analysis of economic added value show that most of the added value from the coffee bean supply chain channel is enjoyed by actors who are directly involved in the supply chain system. The largest value added recipients are farmers and the smallest value added recipients are collectors. Keywords: supply chain system, actors of coffe supply chain, added value of coffee bean

Abstract

Soybean plants (Glycine max (L) Merrill) are annual plants, have white or purple flower colors and have various shapes and sizes for leaf and seed characters. Soybean production in Lampung province in 2015 was 9.82 thousand tons of dry beans, decreased by 3.96 thousand tons (28.76%) compared to 2014. Crop productivity is strongly influenced by the environment and the variety of plants planted, and the spacing is also closely related to the plant population. Spacing arrangement is very influential on plant growth and yield. One of the efforts that can be done to improve soil fertility is by giving compost. Compost is the final substance of a fermentation process of piles of garbage / plant litter and sometimes also includes animal carcasses. This study used a randomized block design with 3 replications, the treatment was given 2 factors, spacing and compost application. The purpose of this study was to increase the yield of edamame soybean optimally with the treatment of spacing and giving organic compost. The results showed that based on least significant different show that the best interaction between spacing planting and compost application on all variable is J2K2 (15cm x 40cm + 12 ton/ha). While the lowest treatment on the J0K0 (15cm x 20cm + 0 ton/ha).

Abstract

The development of off season shallots is still low, this is constrained by the availability of adaptive seeds and appropriate cultivation techniques. The main objective of this study was to obtain adaptive, high-yielding shallot (Allium cepa var Aggregatum L.) in the off season in dry acid soil, Lampung. This research was conducted from February to May 2019 at the IP2TP Garden, Lampung Agricultural Technology Study Center, Natar, Bandar Lampung. This study was conducted using a completely randomized block design with five replications. The treatments consisted of five new purple varieties (VUB) of shallots registered by the Agricultural Research and Development Agency, including Violetta 1 Agrihorti (V1), Violetta 2 Agrihorti (V2), Violetta 3 Agrihorti (V3), Sembrani (V4) and Maja Cipanas ( V5). Observation parameters included growth components (plant height and number of tillers) and yield components (productivity) and shallot quality test (tuber diameter, number of tubers per 100g, percentage of rotten tuber, percentage of moldy tubers, shallot tuber color index, moisture content and tuber hardness index). The results showed that the red onion variety Violetta 3 Agrihorti was adaptive in the rainy season on dry acid soil because it had the best yield and physical quality compared to other varieties because it had the highest productiviy (12,89 ton/ha), the largest tuber diameter (2,2 cm), the lowest percentage of rotten tubers (6.24%) and the lowest percentage of moldy tubers (4.95%), redder tuber color, and lower hardness value or harder texture.

Abstract

The Covid-19 pandemic presents a significant risk for coffee players, especially for Gayo farmers in Central Aceh Regency. Including price risk, supply and demand risk, and supply chain risk. This study aims to study the dynamics of the supply chain in Gayo coffee caused by Covid-19 by measuring the supply level and profits of Gayo coffee actors. The type of data in this study used cross-section data. Data were collected for this study at a particular time. Sources of data in this study include primary data and secondary data. Sample selection was carried out by snowballing a sample of critical cooperatives/gathering traders with the following selection criteria: (i) farmers, collectors, and Gayo Arabica coffee cooperatives connected to the supply chain; (ii) Gayo Arabica coffee farmers, collectors, and cooperatives have experienced and experienced supply chain disruptions during the Covid-19 pandemic. The analysis used in this study uses a dynamic modeling system to simulate changes in inventory levels and profits caused by disruptions in production, supply, and sales). The results influence the level of supply and profits of coffee supply chain actors due to disruption from the COVID-19 pandemic. One of them is a decrease in earnings for coffee players and an increase in supply for sales actors (cooperatives). The increase in operational costs also affects the level of coffee supply chain actors.

Abstract

The livestock sector of East Nusa Tenggara has a large multiplier impact on the welfare and absorption of labor. One approach used to measure the welfare of farmers is the farmer's exchange rate. The study aims to examine the development of the exchange rate of large ruminant farmers in East Nusa Tenggara with quantitative descriptive and the factors that influence it with a multiple regression model. The data used are the exchange rate of livestock sector farmers and the exchange rate of large ruminant farmers during the period from January 2017 to December 2020 obtained from the Central Statistics Agency. The results showed that although the average exchange rate of large ruminant farmers in East Nusa Tenggara was lower than the National average, the trend was increasing. In part, only the wages of farmworkers have a significant effect on the exchange rate of large ruminants and collectively household consumption expenditures; the price of seedlings; prices of medicines and feed; land rent, taxes, and others; transportation costs; the cost of adding capital goods; and the wages of farmworkers are a significant explanation of the exchange rate of large ruminant cattle farmers. Keywords: livestock, ruminants, breeders, welfare
