The experiment aimed to induction of insensitive peanut somatic embryo (SE) to culture filtrate medium from various races of S. rolfsii and its plantlet regeneration. To achieve these objective, the experiments have been done in several steps: somatic embryo development, preparation of culture filtrate (CF) medium from various races of S. rolfsii, induction of insensitive peanut somatic embryo and peanut plantlet regeneration of insensitive somatic embryo. Result of experiment showed that selected SEs on selective medium containing culture filtrate of S. rolfsii one race or two races or three races or four races were specifically insensitive only on selective medium containing culture filtrate one race or two or three or four races of S. rolfsii. All SEs selected in culture filtrate medium of four races S. rolfsii (race 1, 6, 8, and 9) were more insensitive on culture filtrate medium of S. rolfsii races compared with SEs that only selected in culture filtrate medium of one race. Selected insensitive SEs had ability to form normal seedling (50.5-65.5%) and abnormal germinated SEs (23.5 - 30.5%). Normal germinated SEs developed to form plantlets. These plantlets were developed to produced peanut plant R1 generation and peanut seeds. Further evaluation using subsequent generation of peanut (R1 and R2) plants need to be conducted to testing peanut line resistance to stem rot disease (S. rolfsii) in the field.The experiment aimed to induction of insensitive peanut somatic embryo (SE) to culture filtrate medium from various races of S. rolfsii and its plantlet regeneration.

Drying is one way of post-harvest handling to extend the shelf life, especially for agricultural crops. In general, post-harvest drying is only done naturally by using heat from solar energy or commonly called conventional drying. In this study, the grain was dried using a fluidized bed dryer. However, the fluidized bed dryer was modified by adding a pipe heat exchanger. The purpose of this study was to find the effect of grain mass and air intake temperatures on drying time. The Indonesian government has carried out SNI provisions for milling the maximum water content in the material which is 14%. In this study, the grain used was the newly harvested grain where the water content was about 20% with a tolerance of ± 1%. The mass variations in this study were 0.4 kg, 0.6 kg and 0.8 kg and the temperature variations applied were 55°C, 60°C, and 65° C. The results showed the highest heat loss occurs at the highest mass because the air velocity is not able to circulate properly.Drying is one way of post-harvest handling to extend the shelf life, especially for agricultural crops.

The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment. Therefore, the use of organic ferlizer is increased recently. Many authors report that macroalgae is an important source of organic biostimulant and biofertilizer. This is due to the fact that liquid extract contains phytohormone, and solid extract contains essential elements, stimulating growth and production of plants. This article reports effect of solid and liquid extracts on growth and yield of rice plants. Liquid extract (10%) was sprayed during vegetative growth of the plants. On the other hand, liquid extract (5%) was applied directly to growth media. Then, the growth parameters (plant height, tiller number, shoot dry weight and root dry weight), and yield parameters (penicle number and grain weight), were measured during harvesting time. The results show that solid and liquid extracts of Sargassum crassifolium increased the growth and yield of rice plants. This indicates that solid extract of Sargassum crassifolium could be developed as a source of organic fertilizer. On the other hand, liquid extract of Sargassum crassiflium could also be used as a source of organic biostimulant. Both products should support suitable agriculture production.The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment.

Our previous finding showed that the single culture of Lactobacillus plantarum has a maximum time of 18 hours in order to produce carboxyl cellulose and amylase during cassava fermentation. These two enzymes are important in order to give a final characteristic of modified cassava flour including texture, aroma, flavor and taste. The cyanide content of cassava tuber also decreases during its fermentation process. We therefore aimed to modify the starter using co-culture starter of L. plantarum and L. acidophilusand to analyze the production of extracellular amylase and carboxymethyl cellulose during cassava fermentation. The maximum of carboxymethyl cellulose and amylase activity of 13.76 × 10−3 U/ml and 8.31 × 10−3 U/ml, respectively, were obtained from filtrate that has been incubated at 37°C for 23 and 26 h, respectively under static condition. The Km of CMCase and amylase by co-culture starterof L. plantarum and L. acidophilus (1:1) were 0.4791 × 10−3 U/ml and 0.6133 × 10−3 U/ml, respectively.

This research aimed to determine the effect of temperature and time of roasting by using the Gene Cafe’ roaster on the quality of Robusta coffee and determine the appropriate treatment to obtain the best ground coffee. The method used in this research was the experimental Completely Randomized Block (CRB) using 2 factors, which were roasting temperature (225°C and 250°C) and roasting times (10 minutes; 15 minutes and 20 minutes). The parameters observed were chemical quality characteristics (moisture content, ash content, caffeine content), physical characteristics (moisture content, ash content, caffeine content and antioxidant activity), physical quality characteristics (yield, colour and browning index) and organoleptic quality(aroma and taste). Data were analyzed with analysis of variance (ANOVA) at 5%significance level by using software Co-Stat and a significant difference data were tested further by real difference test with Honestly Significant Difference (HSD) test. The results showed that the interaction between temperature and roasting time give significant effect on all parameters, such as moisture content, ash content, caffeine content, antioxidant activity, yield, L* value and °Hue of colour value, browning index, aroma (hedonic and scoring) and taste (hedonic and scoring). The treatment of roasting temperature at 225°C and roasting time for 20 minutes was the best treatment to produce ground Robusta coffee with moisture content 2.63%; ash content 4.66%; caffeine content 2.17%; antioxidant activity 50.93%; yield 73.33%; brown ground Robusta coffee (°Hue value = 16.75 and L* value = 13.93), browning index value 232.89; aroma (strong and slightly like) and taste (bitter and slightly like).This research aimed to determine the effect of temperature and time of roasting by using the Gene Cafe’ roaster on the quality of Robusta coffee and determine the appropriate treatment to obtain the best ground coffee.

Mangrove ecosystems are natural resources in coastal areas that have their own ecological systems, and have contributed as a place for local people to get their daily needs. In this regard, the sustainability of mangroves is a necessity, so that people do not lose their livelihoods. The purpose of this paper is to assess the success of local scale mangrove conservation in its relationship as a place where people looking for the necessities of daily life. Data collected through direct observation, questionnaires, interviews and in-depth discussions. Furthermore, the data were analyzed using descriptive statistical analysis. Mangroves at the study location in their condition before 1980 had not yet been damaged but after that, there was conversion of mangrove land into salt fields, expansion of settlements and shrimp farms. In the early 1990s, mangrove was planted. The results show that a significant number of people who are directly dependent are those who are looking for shellfish, mangrove crabs, shrimp and fish as livelihoods. In addition, community groups that have indirect impacts are those who look for small shrimp in coastal waters as raw material for shrimp paste. In conclusion, the local scale mangrove conservation efforts can be a solution for the livelihoods of local communities. Therefore, a local scale conservation models can add or become a policy choice on a broader scale to maintain the existence of a mangrove ecological system for the environmental and economic needs of the community.Mangrove ecosystems are natural resources in coastal areas that have their own ecological systems, and have contributed as a place for local people to get their daily needs. In this regard, the sustainability of mangroves is a necessity, so that people do not lose their livelihoods. The purpose of this paper is to assess the success of local scale mangrove conservation in its relationship as a place where people looking for the necessities of daily life. Data collected through direct observation, questionnaires, interviews and in-depth discussions. Furthermore, the data were analyzed using descriptive statistical analysis. Mangroves at the study location in their condition before 1980 had not yet been damaged but after that, there was conversion of mangrove land into salt fields, expansion of settlements and shrimp farms. In the early 1990s, mangrove was planted. The results show that a significant number of people who are directly dependent are those who are looking for shellfish, mangrove crabs, shrimp ...

In the exploration of eaglewood species in Buru Island, Maluku Islands, Indonesia on February 1-5, 2017, three noteworthy eaglewood species were found. One species was Gyrinopsmoluccana(Miq.) Baill in Namrinat village and Tikbary village, Namrole district, South Buru. This species has been mentioned in 1959 by Hou and Keliopas in 2013, however they were found in Kayeli area, North Buru. Three other species of eaglewood were new records to Buru. Two newly recorded species, first Gyrinopsdecipiens Ding Hou that was found at Waeduna Mount, Bara village, Aer Buaya district, North Buru and second GyrinopssalicifoliaRidl. from Tikbary village, Namrole district, South Buru. One genus was a new record to Buru island, namely Aquilaria. Its species was Aquilarifilaria(Oken) Merr.that was found together with G. salicifolia in Tikbary village, Namrole district, South Buru.In the exploration of eaglewood species in Buru Island, Maluku Islands, Indonesia on February 1-5, 2017, three noteworthy eaglewood species were found.

A mine clearing machine, which is the solution subject of this article, is a mobile machine intended for a detection of mines in a terrain. The machine is able to move in the rugged terrain due to a wheel-tracked chassis, which can be modified to be purely wheeled in order to drive on roads. The objective of this article is the modification of this wheel-tracked chassis, because the current stage of this chassis meets problems consists in formation of cracks in its steel track. The design modification of the chassis goes from structural analyses of the original design of the chassis. There were carried out strength calculations of the original one to find out, in which location of the track and which values stresses are reached. Analyses have served as a basis for the design of a tension mechanism. Two variants of the tension mechanism were developed. Both variants of the mechanism are analysed from the strength point of view in order to identify the distribution of stresses in the structure.A mine clearing machine, which is the solution subject of this article, is a mobile machine intended for a detection of mines in a terrain.
