Abstract

Pratama et al, 2018. Oil Palm Breeding Program Strategy for Suboptimal Area in PT Binasawit Makmur  . JLSO 7(1):26-36. Suboptimal areas have great potential to be used an alternative land for cultivation of oil palm.We needed superior oil palm material to be able to grow well on that land. PT. Binasawit Makmur (BSM) through the Breeding Unit has developed a strategy regarding the assembly of superior material oil palm drought resistant. Therefore, this research aimed to develop  a strategy regarding breeding program in suboptimal lands of PT Binasawit Makmur.  The strategies used were  introducing, evaluating, and selecting genetic material based on productivity components (total and weight of fresh fruit bunches/ha, extraction rate) and high increment.  In addition, the efforts have been made to obtain drought tolerant material are conducting a progeny trial (DXP Trial) on mature palm to obtain drought tolerant in the dried season. Based on the results of the progeny trial, both of parents were traced to a crossing program. Currently, the seeds of the crossing have been obtained to confirm the results of the research on the nursery scale. In the nursery trial, research will be conducted to measure the proline content, stomata and chlorophyll content. Selection in the mature palm DXP progeny trial was followed by application a molecular tool such as SSR and SNP. Through this approach, a superior genetic material in terms of productivity and also drought tolerance can be developed and therefore can be used for recombination and release of new varieties.

Abstract

Lastinawati et al, 2018. Price Transmission Analysis of Rice in Ogan Komering Ilir District, South Sumatra Province. JLSO 7(1):43-49. Price transmission is one indicator of whether or not a marketing system is efficient and also can explain the distribution of welfare between producers and consumers in the marketing channel. This study aimed to analyze the transmission of rice prices which are the basic needs of the Indonesian people, both the price transmission of consumer to farmers, and vice versa, with two groups of rice based on their quality, namely premium and medium rice. This research conducted at Ogan Komering Ilir District, South Sumatra Province. Price transmission was analyzed using price transmission elasticity, using weekly rice price series data from the second week of March 2016 to the second week of September 2018. The results showed that the transmission of consumer prices of premium and medium rice to the price of harvested dry grain at farmer level had an elasticity value not equal to one, and vice versa. This showed that the rice market in Ogan Komering Ilir Regency was in elastic and less efficient, because prices were transmitted asymmetrically.

Herlina et al, 2018. The Evaluation of Climate Change and The Effect to Cropping Pattern, Panting Season and Productivity of Soybean (Glycine max L. Merrill) in Malang Regency, East Java. JSLO 7(2):106-120. Climate change is a negative impact due to development activities on Earth. Forests that lose function caused degradation and increases in greenhouse gas concentrations cause global warming and trigger climate change. Climate change is thought to affect cropping pattern, planting time and soybean productivity. The purpose of the study was to evaluate the expected climate change and analyze correlation between climatic elements and the pattern and time of planting and soybean productivity. The research was carried out in March to April 2018 in Kalipare, Donomulyo, Singosari and Dau, Malang Regency, East Java. The tool used is a questionnaire. The material are the climate elements, soybean productivity and interview data. This study uses survey research methods. Total respondents were 40 farmers. Climate change analysis by analyzing mean changes in temperature, rainfall and number of rainy days in period 1 (1988-1997), period 2 (1998-2007) and period 3 (2008-2017). Correlation coefficient analysis is used to determine the correlation between climatic elements and soybean productivity and followed by t test. The results show that climate change has occurred in Malang Regency for the past 30 years. The correlation between temperature, rainfall with soybean productivity showed a "low" correlation, while number of rainy days with soybean productivity had a "very low" correlation. Temperature significantly affected soybean productivity in Malang Regency. Soybean cropping patterns was not affected by climate change, but planting time was influenced by shifting seasons.
