Abstract

Microbial N2-fixer and P-solubilizer were innoculated in a mixture of fresh manure and phosphate rock formulated as an Organonitrophos fertilizer. The population dynamics of bacteria and fungi growing during the composting process were observed. The inoculation treatments consisted of: K = mixture of 20% phosphate rock and 80% of fresh manure + decomposers (control), N = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + N2-fixer (Azotobacter and Azospirillum sp.) , P = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + P-solubilizer (A. niger and P. fluorescens), and NP = mixture of 20% phosphate rock and 80% of fresh manure + decomposers + N2-fixer + P-solubilizer. The results showed that inoculation of microbial N2-fixer and combination inoculation of N2-fixer and P-solubilizer increased the total bacterial population compared to that of the control as well as the only inoculation of microbial P-solubilizer on the 14th day of observation in which the bacteria reached the highest population. On all the observation days, the population of fungi in the inoculation of microbial P-solubilizer treatment increased significantly compared to that of the control. However, there was no difference between the populations of fungi in the inoculation of N2-fixer and combination inoculation of N2-fixer and Psolubilizer. The genus of fungy identified in the compost of the mixture of fresh manure and phosphate rock were Chytridium sp., Aspergillus sp., Rhizopus sp., and Fusarium sp.[How to Cite : Nugroho SG, Dermiyati, J Lumbanraja, S Triyono, H Ismono. 2013.

Abstract

Most of the coffee production areas in Lampung are in the vicinity of production forests andprotected forests, also a catchment area for watersheds in Lampung, namely Sekampung andWay Seputih watersheds. Continuity of sustainable coffee production lines is an importantdemand that needs to be done. The application of coffee production systems with shade(agroforestry) in the catchment area is very important in ensuring environmentalsustainability. This study aims to analyze the income performance of agroforestry coffeebased on the land status in Hulu Das Sekampung. The research uses survey methods. Fielddata exploration conducted in April-November 2016 is located in Datar Lebuay and SinarJawa Villages. Air Naningan, Tanggamus, Lampung. The descriptive statistical analysismethod is used to explain the performance of agroforestry coffee production at the researchlocation. Based on the results and discussion it was concluded that farmers with landownership status had the highest level of coffee farming income compared to the land statusof HKm and non-HKm. Agroforestry coffee farmers obtain sources of income from coffeeproduction, MPTS production, and other crop production (multiple cropping). The averagecontribution of coffee farming income is 22% of the total farm income. Coffee contributes22% to the total income of farmer households. Farmer's household income with the status ofland ownership is the highest compared to the land status of HKm and Non-HKm. Thediversity of income sources of upstream farmers in the watershed. The villages that comefrom various vegetation plants are important in maintaining land cover as a catchment area.The practice of agroforestry coffee is an adaptation of sustainable production in the upperwatershed Sekampung. The pattern of agroforestry coffee production in the area aroundprotected and watershed forests needs to be continuously developed.

Abstract

Coffee price is an important indicator that stimulates farmers to advance their welfare. Unfortunately, coffee crisis makes the farm gate price uncertain and volatile. This study aims to explore the Indonesian coffee export situation related to price risks and coffee market integration between Indonesian coffee price and international price. The time series data were the coffee price from 1987 to 2014 in Indonesian domestic market and in global trade in London. Vector Error Correction Model (VECM) approach was applied to test market integration based on Ravallion’s equation. Based on the analysis, the results of the study revealed that Indonesian coffee export performed progressively in the last decade. Export destination countries for Indonesian coffee also developed broadly.  There was market integration on the Indonesian coffee market and global price in the London terminal.  Although not fully, the shock in the international price was somehow felt in the Indonesian coffee market.  There were sufficient shreds of evidence to conclude that the Indonesian coffee market is well integrated with the international market in the long run. The changing coffee price in Indonesia and the International market adjusted in the next three years.  In short term, Indonesian coffee price was 76% influenced by international price changes, but not vice versa.JEL Classification D49; Q02; Q17

Abstract

Water is one of important things for the process of rice field farming. Irrigation as one of water sources for rice farming needs to be managed and maintained. The role of farmers is very important for irrigation management efforts.  The contribution of farmers in the repair and management of irrigation can be realized in the form of willingness to pay (WTP) of irrigation management services. The benefit of paying for irrigation management services is that it can be used for better irrigation management and maintained water adequacy. This study aims to determine the value of willingness to pay from farmers that use irigation from the Way Ketibung’s Irigation Area in Lampung Selatan regency, and the factors influence it.  Data collection was conducted in Sidomulyo and Candipuro district, Lampung Selatan in Juni - September 2020.  The number of samples of this research is 100 farmers who used irrigation for rice farming selected by using  propotionate random sampling method from total population of 1223 farmers. The data are analyzed using contingent valuation method (CVM) and ordinal logistic.  Based on the research results, average WTP value of irrigation management service in the Way Ketibung’s Irigation Area was IDR97,400.00 /Year, or IDR48,700.00 /Planting Session. The factors that influenced were land area and farmer’s knowledge of irrigation function

Abstract

Rampai tomato (Lycopersicon pimpinellifolium) is one important vegetable in Indonesia.  The production of rampai tomato increases every year, indicating a good opportunity for the tomato  in market. In the process of cultivation, fertilization is a very important aspect.  Advances in technology have invented some importantagricultural inputsespecially for chemical fertilizers such as Urea, TSP, KCl, NPK, and others.  Nowadays, small scaled farmers frequently face difficulty to get chemical fertilizers on market because ofeither scarcity or high price.  This condition needs to be well anticipated.  Reducing the use of chemical fertilizers by using organic fertilizers which isproduced from local and cheap natural resources is a somewhat promising solution.The organic fertilizer tested in this study is an alternative fertilizer called Organonitrofos.  Organonitrofos fertilizer is made from 70-80% cow dung and 20-30% phosphate rock, in the previous research.  Both the materials are locally available in Lampung.  This fertilizer then needs to be tested to ensureits consistency on plant production.  In this study, Organonitrofosfertilizerwas testedon rampai tomato plantsin pots (pot experiment).The study aimed  (1) to test the Organonitrofos fertilizer on the response of rampai tomato plants in pots (2)reduce the useof chemicalfertilizersin the production oframpai tomatoplants.The pot experiment was conducted in the Integrated Field Laboratory of the Faculty of Agriculture University of Lampung on January - April 2012.  The experiment used Completely Randomized Design (CR) with 7 treatment (7 combinations between chemical fertilizer and Organonitrofos), 4 replicates each.  Data collected was analyzed by using ANOVA and followed by LSD.  The variables observed were agronomic aspects (such as plant height, biomass, and production) and water consumption.  The results showedthat,based on theplant responsevariablessuch asplant height, upper and biomasses, andcrop production, treatmentC(100% Organonitrofos with 5000 kg/ha dose) was significantly different and better from every other treatment. Based on the water consumption (evaporationand irrigation), all the treatments were not significantly different.  However, the research showed that the use of 100% Organonitrofos fertilizer (5000 kg/ha); resulted in the highest water productivity (yield/water consumption).  This research also showed that the use of chemical fertilizersbe could significantly reduced by using combination between chemical fertilizers and Organonitrofos. Keywords: Rampai tomato , fertilizer, organonitrofos, plants response.
