Abstract

Land tenure can be used as an illustration of equity control of the main production factors in the agricultural sector. Changes in agricultural land tenure structure will affect agricultural production (farming) both in terms of efficiency and farm income, while the pattern of land ownership represents the state ownership of the main production factors in agricultural production. The purpose of this study was to analyze the factors that influence the choice of tenure to the use of inputs, attitudes, motivation, work ethic, production and income. The research location is determined by using purposive sampling method, i.e. selecting the study area based on the characteristics or specific reasons are deemed to have a close relationship with the problems examined. The selected area in this study was Sigi District where became one of the centers of rice production, furthermore Subdistrict Gumbasa have been selected because as one of the centers of rice production also has the status of land tenure are more varied in Sigi District. The District Gumbasa selectived 2 Villages where has the highest number of rice farmers such as the Pakuli and Kalawara Village. Respondents in this study amounted to 99 respondents. Factors that affect the status of tenure choice can significantly increase the probability of tenure including the production, input prices, output prices, household income and work ethic, while the factors that were not affect the land tenure were motivation, use of labor and attitudes of farmers.

Abstract

The research aimed to discover the response of the growth of two spinach species on Nutrient Film Technique (NFT) hydroponic system and the concentration of the appropriate AB Mix solution on each species. The research was conducted in January to February 2016, at Green House, Faculty of Agriculture, Tadulako University by using Split Plot Design method. The main plot was red and green spinach, while the subplot was the concentration of AB Mix nutrient solution, namely 4 ml/L of water, 5 ml/L of water, 6 ml/L of water and 7 ml/L of water. The research findings reveal that AB Mix nutrient solution was generally very good to support the growth of spinach on NFT hydroponic. The green spinach had better response rather than the red one. There was no interaction between species and the concentration of nutrient solution. The good concentration of nutrient solution for green spinach is 6 ml/L. It was showed by the better growth of plant height on all age of plant, the more number of leaves, the canopy and the root (wet and dry) were heavier, while on the red spinach, 5 ml/L of concentration of nutrient solution resulted in the best growth, yet it was not significantly different from other concentration except on the parameter of plant height and the dry weight of plant canopy.

Abstract

Yantu et al. developed the prototype of smallholder cocoa farm. The aim of this study is (i) to test effect of application of biological agent to productivity of cocoa farm; and (ii) to test workability of the prototype based on the application. Design of the research was completely random design. There were 4 treatments for every object (cocoa black pod (CBP), vascular streak dieback (VSD), and pod borer (PB), 6 repetition, and 4 observation times. The result of analyzes showed that the treatments significantly effect to the decreasing of attack level of CBP, VSD and PB at level of alpha 0.05. The result of Tukey’s method showed that two treatments significantly difference from control, namely P2 (spraying with Trichoderma sp. for CBP and VSD, and with B. bassiana for PB), and P3 (spraying with Trichoderma sp. and giving compost plus Trichoderma sp. for CBP and VSD, and with B. bassiana giving compost plus Trichoderma sp. for PB). Iterating the primary data of the treatments both to the prototype can be predicted event of decreasing of pod damage, namely 75 – 93 percents. That signed that the prototype put to a test its workability. The hypothesis value for decreasing was just 35.69 percent. In consequence of the decreasing is the increasing of the productivity minimal 3.36 in magnitude.

Abstract

Water is a main factor on production input in rice farming. The need for water will increase as time progresses, but the availability of it is increasingly uncertain. One way to overcome the scarcity of water is the efficient using of water by determining the price of irrigation. This study aims to determine the price of water which is probably paid by farmers in rice farming, and to know the constraints faced by them. The research design used is quantitative descriptive. Primary data are obtained from 80 farmers taken by simple random sampling. Data analysis’ used here are analysis of descriptive, analysis of farming, and analysis of Willingness To Pay (WTP). The result of this research shows that the value of water rent in Buahdua Village is Rp. 4,428,031/ha/MT. Interviews show that almost all farmers are willing to pay the price of irrigation. The average value of PAP respondent is Rp. 61,813/ha/MT and the average value of TWTP is Rp. 28,751.891. Many obstacles faced by farmers in the use of irrigation is garbage, difficulty of getting water during the dry season, and damaged irrigation. This condition will affect the increasingly inefficient management of irrigation. Therefore, the economic value of water usage can be used as a reference asafees level by the farmers to reach efficiently.

Abstract

Data in 2012 explained that Indonesia had dry land about 148 million ha (78%) and wetland by 40.20 million ha (22%) out of 188.20 million ha of the total land area. The variety of rice which can grow and produce well on marginal land such as gogo rice is very indispensable. This research aimed to find the gogo rice cultivars that can germinate normally in particular osmotic pressure and the tolerance limit on the drought by using PEG 6000 solution. The research was prepared with two-factor factorial design by using Completely Randomized Design. The first factor consisted of three gogo rice cultivars, namely 1. siang, 2. Pulut ko, and 3. roda, while the second factor consisted of four treatments, namely 1. water as control of 2. -1 bar, 3. -2 bar, and 4. -3 bar.Thus, there were 12 combinations of treatment in which each treatment was repeated four times. In the experiment Rolled Paper placed in plastic test method was used in which there were 50 items in each experiment unit.The variable observed was potential for growth, percentage of germination, and germination rate. The research findings reveal that the three cultivars were able to germinate normally only up to -1 bar osmotic pressure, while the pulut cultivar had higher germination capacity compared with siang and roda cultivars up to -3 bar PEG 6000 osmotic pressure. Siang cultivar and -1 bar osmotic pressure gave potential for growth, germination capacity, and germination rate.
