Artemisia is one of the plants that can be used as an alternative medicine for malaria. The Artemisia plant contains secondary metabolites in the form of artemisinin compounds that function as antimalarials. One of the efforts that can be done to increase the growth of Artemisia annua. plants is by using a growth regulator of gibberellins (GA3). Using a Randomized Block Factorial Designs (RBFD) with the first factor being the concentration of 50 mg.L-1 (K1), mg.L-1(K2), 150 mg.L-1 (K3), 200 mg.L-1 (K4). The second factor has 3 frequencies, 1 time giving 7HSPT (F1), 2 times giving 7HSPT and 14HSPT (F2), and 3 times giving 7HSPT, 14HSPT and 30HSPT (F3). In addition, there were plants that were not given GA3 control (without treatment). Parameters observed were plant height, leaf area, glandular trichome density, and plant dry weight. The results showed that the administration of gibberellins (GA3) with different concentrations and frequencies on plant height, leaf area, glandular trichome density, and dry weight of A. annua plants had no significant effect. Plants have not been able to grow properly because the provision of gibberellins that have not been active stimulates all plant tissues and directly seeps through the roots, stems and leaves.

Soybean is planted in some types of land agroecology, but production centers are mostly on peat and tides. This research was conducted at the soybean center in Rantau Rasau District with agroecology peat and tideland. The trial was arranged in a Randomized Block Design (RBD) with ten treatments and four times repeatitions. It consisted of several doses of organic material decanter cake (DC) and the percentage of the recommended amount of mineral fertilizer (RDF). RDF was selected based on Indonesia Food Crop Agriculture Service. Decanter cake from palm oil mill waste was used as a source of organic material. Experimental parameters are plant height, leaf number, grain yield, 100 grain weight, and the number of pods, seeds per pod, and plant. The result indicated the combination of mineral fertilizer and organic material DC had significant differences in increasing plant height and number of leaves. Different types of RDF and DC combinations showed substantial effects on the soybean yield and yield components. The combination of RDF 25% and decanter cake at any dose positively impacted soybean height, leaf number, and grain yield component. The highest dry seed yield of 2.48 tons per hectare was achieved by a combination of 25% RDF and 20 ton ha-1 decanter cake. Soybean yield in this study was higher than Anjasmoro’s description of 2.03–2.25 tons ha-1

Tomato (Lycopersiconesculentum Mill. cv. Rampai) is rich in lycopene, a carotenoid group compound with many biological activities, one of which is as an antioxidant. Conventional tomato cultivation is not optimal due to the susceptibility of tomato plants to pests and diseases, even though the need for lycopene continues to increase. Plant tissue culture method can be one solution for lycopene production. Callus tomato cv. Rampai was initiated from cotyledons on MS medium (Murashige& Skoog) with the addition of 1 ppm BA (benzyladenine) and 1.5 ppm IAA (indole-3-acetic acid). Callus aged one week to four weeks were harvested and lycopene was extracted by maceration method using hexane:acetone (9:1) as solvent. The presence of lycopene in callus was confirmed by TLC (thin-layer chromatography) (retention factor value/Rf = 0.56) and UV-Vis spectrophotometry (wavelength that gives maximum absorbance = 472 nm). Lycopene content in tomato callus increased with increasing callus age and was directly proportional to the callus growth index. The highest lycopene level was found in callus aged 4 weeks, which was 0.3094 mg/100 g dry weight callus.

Maize and soybean have been widely cultivated in dryland. However, their productivity is relatively low. Turiman Jale cropping system was then established as an innovation to increase productivity by intercropping maize and soybean with proper arrangement of population and cultivars used. This study aimed to determine the best Turiman Jale cropping system model for increasing crop productivity, thereby improving the income of dryland farmers. The research was conducted during the second planting season 2019/2020 at the dryland of the Sadar Karya II Farmers Group, Sumberwojo, Sidorejo, Ponjong, Gunungkidul. It was arranged in a Randomized Complete Block Design (RCBD) consisting of 10 cropping systems, namely Jale 2:3 (cv. P36-Dega1)(40x20cm), Jale 2:3 (cv. P36-Dega1)(40x30cm), Jale 2:3 (cv. P36 -Dega1)(40x40cm), Jale 2:4 (cv. Bisi2-Dega1)(40x30cm), Jale 3:3 (cv. Bisi2-dega1)(40x30cm), Jale 2:6 (cv. NK212-Dega1)(40x30cm), maize monoculture (cv. Bisi2) (80x40x30cm), maize monoculture (cv. NK212) (80x40x30cm), maize monoculture (cv. Pioner36) (80x40x30cm), and soybean monoculture (cv. Dega1)(30x15cm). Observation was made on plant growth and yield variables. Land Equivalent Ratio (LER), Area Time Equivalent ratio (ATER), R/C ratio, B/C ratio, and Marginal Benefit Cost Ratio (MBCR) were also measured. The data were analyzed using ANOVA then further tested for orthogonal contrast and Tukey’s test with 5% significance level. The results showed that Jale 3:3 (Bisi2-Dega1)(40x30cm) resulted in the highest productivity, which was 5.890 ton ha-1 for maize and 2.209 ton ha-1 for soybean, with high LER of 1.79, high ATER of 1.90, R/C ratio of 2.33, B/C ratio of 2.39 and MBCR of 1.23, making it profitable and feasible.

Palm oil is Indonesia’s competitive advantage in the international commodity market. Various derivative products are produced by palm oil. However, the European policy banning palm oil exports has become an obstacle to Indonesia’s palm oil export performance. Environmental issues are the reason for the ban on imports of Indonesian palm oil. However, in this research, we try to extend the view of sustainable issues. This study uses Indonesian palm oil exports and the European rapeseed oil trade to explain this issue. In this study, we try to explain a pure European policy of sustainability or protectionism. Based on the analysis results, it was found that this policy was strongly influenced by exports and production of European rapeseed oil. The effect of rapeseed oil production on palm oil imports proves that this policy has an element of protectionism to protect European rapeseed plants

One of the factors that influence national rice production instability is an attack of tungro disease that can lead to decreased production by up to 90% even if attacking in the vegetative period can cause crop failure. To reduce tungro disease in the field can be by using resistant varieties which are the most effective components in tungro control.Advanced yield trial is one step toprocess of producing tungro resistant varieties. This research aimed to identify the results of tungro resistant strains that have higher phenotypic character and yield potential than other tungro resistant varieties. The research was conducted at Tungro Disease Research Station, Lanrang Sidrap from December 2017 - March 2018 using a Randomized Complete Block Design (RCBD). were tentungro resistant lines and check varieties i.e Inpari 7 Lanrang and Ciherang and it was repeated 3 times. Data were analyzed using the F test and tested for significance with the Least Significant Difference (BNT). Correlation test was conducted between growth components, yield components and yields. The results showed that the lines tested had different >performances on the growth component, yield component and yield.There are three lines, namely BP12280-3f-7-Kn-2-1*B-Lrg-1-1-10-9, BP12206f-8-3-2*B-LR-20-4 and BP12280-3f-7-Kn-2-1*B-Lrg-1-16-14 which produced the highest productivity, which was supported by the number of filled grain per panicle and the number of panicles per clump.Flowering age 50%, number of panicles and number of filled grains were positively correlated with grain yield.

Potato self-sufficiency in Indonesia faces three main problems: rising air temperatures, limited availability of low-temperature land suitable for potato cultivation, and lack of high-temperature tolerant potato varieties. Therefore, it is necessary to identify the tolerance of potato variety to high-temperature. This research was conducted in two locations: the optimum temperature location and the high-temperature location, using nine varieties, are Agria, Andina, Amabile, Cingkariang, Granola L, Granola K, Margahayu, Olympus, and Tedjo-MZ. The study design uses a split plot with three replications. Differences in temperature as the main plot and varieties as subplots. Parameters observed were air temperature, growth, and yield of potato tubers. The analysis carried out were the Stress Sensitivity Index (SSI), Stress Tolerance Index (STI), Yield Stability Index (YSI), and Cluster Analysis. The results showed that there were no tolerant to high-temperature varieties. Based on the STI, only Olympus was a medium tolerant of high temperatures. Based on the Stress Sensitivity Index (SSI), four varieties are moderately susceptible to high temperatures (Olympus, Andina, Cingkariang, and Margahayu). The YSI analysis shows the same results as the SSI. The cluster analysis results showed harmony between the results of the stress index analysis and cluster analysis. Nine varieties had a high similarity (87.3%), meaning that all varieties had the same characteristics and less tolerance to high temperatures. Olympus was the more tolerant variety to high temperatures, followed by Andina, Cingkariang, and Margahayu. The four varieties consider promising potato lines in high-temperature areas.

Red chili (Capsicum annum L) is a kind of horticulture that has been high economic and nutrient value, so it’s impotent to increase the yield. With the modern technology in agriculture, many farmers have been planting without using soil such as aquaponics, especially for vegetables. This study aims to determine the most suitable planting media for the growth and yield of 3 red chili varieties. This research was used a factorial Randomized Complete Block Design (RCBD) with 3 replicates, which first factor was used 4 growing media (Cocopeat, husk charcoal, tankos and a combination of all) and the second factor was used 3 varieties of red chili (Kirana, pasemah and terano). Parameters measured; plant height, number of leaves, number of branches, number of fruits and weight of fruits. Tankos media and terano variety have a significant effect on plant height and leaf number, during the 4 weeks of observation. The number of branches and number of fruit, for both the treatments of the planting media and the varieties, were not significantly different, but the yield was significantly different as compared among them with terano was the better.

With the modern technology in agriculture, many farmers have been planting without using soil such as aquaponics, especially for vegetables. This study aims to determine the most suitable planting media for the growth and yield of 3 red chili varieties. This research was used a factorial Randomized Complete Block Design (RCBD) with 3 replicates, which first factor was used 4 growing media (Cocopeat, husk charcoal, tankos and a combination of all) and the second factor was used 3 varieties of red chili (Kirana, pasemah and terano). Parameters measured; plant height, number of leaves, number of branches, number of fruits and weight of fruits. Tankos media and terano variety have a significant effect on plant height and leaf number, during the 4 weeks of observation. The number of branches and number of fruit, for both the treatments of the planting media and the varieties, were not significantly different, but the yield was significantly different as compared among them with terano was the better. It is clearly that, for high yield is terano variety, while the good medium is tankos.

In food chain of terrestrial ecosystem, ants have roles as predator of other arthropods, eater of seed, nectar, plant and aphid secreation, and fragmenter of dead organic matter. This research wanted to know the ant biodiversities and dominant ant species at Bendosari Park ecosystem, Salatiga municipality. Sampling technique used pitfall-trap in 10 zones that every zone had different trees composition. Each zone put five pitfall-traps,for 2x12 hours that were collected at 06.00 and 18.00. Observation was done eight times, every two weeks. Research result got five sub families, 16 genera, 20 morfospecies and 1462 individu. Species richness index of ant at 06.00 and 18.00 were 2.48 and 2.35. Species eveneess index of ant at 06.00 and 18.00 were 0.76 and 0.54. Species biodiversity index of ant at 06.00 and 18.00 were 2.19 and 1.60. Species biodiversity index of ant that relatively high was found at zone 2 and relatively low was found at zone 6 eventhough there was not different from one zone to others.

Imported soybeans have dominated national soybeans for more than two decades. To reduce dependence on imported soybeans, efforts are needed to maximize national soybean production and productivity through technological innovation. Soybean high yielding varieties are one of the easiest technologies to be adopted by farmers. The assessment aims to evaluate perceptions, attitudes and satisfaction of farmers with the attributes of superior soybean varieties. The assessment was carried out using a survey method of soybean farmers totaling 32 people in The Kebumen Regency. High yielding soybeans varieties studied is Grobogan, Anjasmoro and Gema varieties. Attributes evaluated are plant performance, yield, soybeans price selling, easier seeds to obtain, harvest age, the suitability of seed size to demand and pest resistance. Farmers’ perceptions were mapped using perceptual mapping, farmer attitudes were analyzed using the Fishbein Multiattribute Model and farmer satisfaction was analyzed using the Customer Satisfaction Index (CSI). The results of the study showed that farmers had better perceptions, attitudes and satisfaction towards Grobogan and Anjasmoro varieties compared to Gema variety. Grobogan and Anjasmoro varieties were perceived as more excellent because they had more attractive plant diversity, higher production, easier seeds to obtain and more resistance to pests-diseases. Farmers showed a more accepting attitude to cultivating Grobogan and Anjasmoro varieties with Fishbein Multiattribute scores of 45.63 and 43.93, while the Gema variety only scored 39.64. Farmers have a higher level of satisfaction with Grobogan and Anjasmoro variety with CSI values of 52.11% and 50.37% compared to the Gema variety of 44.66%.
