Abstract

Tanaman soba (Fagopyrum esculentum) berasal dari wilayah subtropis, berpotensi sebagai pangan fungsional karena mengandung senyawa flavonoid antioksidan yaitu rutin. Kadar rutin sangat dipengaruhi oleh lingkungan. Penelitian ini bertujuan untuk mengetahui potensi tanaman soba sebagai sumber bahan pangan fungsional. Penelitian dilaksanakan di Kebun Pembibitan, desa Kopo (600 meter dari permukaan laut) Kabupaten Bogor, Jawa Barat, dari bulan Mei sampai Juli 2012. Metode yang digunakan adalah rancangan petak tersarang dalam rancangan acak kelompok dua faktor dengan tiga ulangan. Faktor pertama adalah naungan terdiri dari dua taraf, yaitu: tanpa naungan, dengan naungan paranet 55 persen, dan faktor kedua adalah populasi terdiri dari dua taraf, yaitu: 200 tanaman/m2, 50 tanaman/m2. Hasil penelitian menunjukkan produksi biji terbanyak pada kombinasi perlakuan tanpa naungan populasi 200 tanaman/m2 (N0P1) sebesar 764,3 g/m2 atau 7,643 ton/hektar dan terendah pada perlakuan dengan naungan paranet 55 persen populasi 50 tanaman/m2 (N1P2) sebesar 146,0 g/m2 atau 1,46 ton/hektar. Kadar rutin tertinggi diperoleh pada perlakuan tanpa naungan sebesar 0,398 mg/g biji. Produktivitas kadarrutin biji soba sebesar 304,19 mg/m2. atau 3,04 kg/hektar.Buckwheat (Fagopyrum esculentum), originated from subtropical regions, has the potential as a functional food because it contains flavonoid, called rutin. Rutin concentration is greatly influenced by the environment. The objective of this study is to determine the potential of the buckwheat plant as a functional food. The research is conducted in the nursery garden of Kopo village (600 m asl), Bogor District, West Java, from May to July 2012. The method used is the nested plot design in a randomized complete block design with two factors and three replications. The first factor is two levels of shading namely without shading and with shading of 55 percent paranet. The second factor is two crop densities namely 200 plants/m2 and 50 plants/m2. The research results show that the highest grain production (764.3 g/m2 or 7.643 tons/ha) is in the combination treatment of NOP1 and the lowest one (146.0 g/m2 or 1.46 tons/ha) is in N1P2 treatment. The highest rutin concentration is obtained on the treatment without shade at 0.398 mg/g groats. The productivity of rutin concentration of buckwheat groats is 3.04 kg/ha.

Abstract

Extreme weather conditions due to strong wind and high rainfall cause rice lodging. Lodged plants have lower photosynthetic rate and nutrient transport capacity which resulting in lower rice quality. However, physiological process of rice plant under lodging condition is rarely reported. Therefore the objective of this research was to evaluate the biochemical compounds of two rice varieties under artificial lodging treatment. IR64 and HIPA8 varieties were planted at the Experimental Farm in Leuwikopo, Bogor Agricultural University (IPB) in November 2016 to June 2017. At grain filling stage, rice hills were enforced to lodge using manual force until culm break. Analysis of untargeted biochemical compounds was conducted at Research and Development Institute, Laboratory of Regional Health, DKI Jakarta where rice culms from upper and below breaking position were compared. Results showed that rice culms had different biochemical compounds after lodging, especially in fatty acid, terpene, alkane, and steroid group. Lodging culms had a total of 22 to 25 compounds compared to 15 to 17 of the normal plants. It means that lodging stimulated different physiological process in rice plants. A decrease in fatty acid and an increase in the steroid level of lodged plants indicated an increase in oxidative stress of lodging condition. It is possible that low rice grain quality under lodging condition was caused by the changes in the plant physiological processes in response to the environmental stress.Keywords: extreme weather, metabolomics, oxidative stress, rice culm, rice lodging

Abstract

Climate change is believed to increase the intensity and the frequency of extreme weather events in reference to strong winds and heavy precipitations. The extreme event is defined as strong wind at speed of 50 km.h-1 and rain fall intensity 10 to 20 mm.h-1 or more .  This condition is detrimental to rice production as this may lead to lodging and flooding which normally occurs during the grain filling stage to harvesting resulting in lower yield and grain quality.  The. Simultaneous extreme events and critical rice growth occured more frequently due to increasing cropping season within a year in Indonesia. Therefore, it is important to mitigate and develop adaptation strategies in order to sustain rice production. Efforts to adapt to these extreme environmental conditions are mostly based on genetics and agro ecological approaches. Genetically, rice with strong hills, high aerodynamic with low water retention is desired. Agro-ecological manipulation is conducted through wind break application, planting arrangement to facilitate better sunshine penetration, to manage water level and planting calendar. Availability of weather station in the field is important to improve mitigation and continuous adaptation strategy against extreme weather events. Keywords: plant canopy architecture, climate change, heavy rainfall, lodging, strong wind

Abstract

Studies about lichens and pollution in South-East Asia are restricted because the lichens are poorly known. A research project about air quality bioindicator using epiphytic macrolichens in Bogor City was conducted from March 2012 until July 2013. Purposive sampling method was applied in 3 plots: plot 1 was in the centre of Bogor Botanical Garden (BBG) that far from busy roads, plot 2 was in a part of BBG adjacent to main and busy roads, and plot 3 was along busy roads and near a factory. In each plot, macrolichens were observed in 8 canary trees using 2 mini quadrats (32 x 20 cm2). The population conditions of epiphytic macrolichens were analyzed and to be used as bioindicator of air quality. Seven genera of macrolichens were found: Coccocarpia, Leptogium, Canoparmelia, Parmotrema, Dirinaria, Physcia, and Pyxine. Plot 1 was having Coccocarpia and Leptogium that were not found in other plots and therefore they can be used as sensitive bioindicators, none of Canoparmelia and Pyxine, a few and infrequent Dirinaria but with larger average coverage (AC = 6.15 cm2), and Physcia was found abundantly (sensitive bioindicator). Conversely, plot 2 and 3 were having none of Coccocarpia and Leptogium, few or many Canoparmelia and Pyxine and therefore appeared to be tolerant, many and frequent Dirinaria but with smaller AC (plot 2 = 2.85 cm2, plot 3 = 1.16 cm2), and few or none of Physcia was found. Being found in all plots, Dirinaria showed a clear pattern of increasing thallus number and decreasing AC from plot 1 to plot 3, so it can be used as tolerant bioindicator. Conversely, Parmotrema had unclear pattern of population condition. Similar researches on different trees are necessary to explore more details regarding epiphytic macrolichens population condition.

Abstract

AbstractRice lodging due to incident of extreme weather, i.e., combination of strong winds and high rainfall is eviden in Indonesia. However, yield loss in the area is rarely studied. In order to estimate yield loss on rice, a model for calculating the yield reduction was developed. The objective of present study was to analyze the effect of strong winds and high rainfall incidents on yield loss of rice in the field. The study was conducted at the Sawah Baru IPB, Bogor, Indonesia from February to April, 2016 on rice plots severe from natural incident of strong wind and high rainfall. The results showed that rice lodging from strong wind and high rainfall formed patterns and specific formations. We determined four major lodging formations,  five lodging degrees, and eleven different patterns due to wind direction. Overall, lodging occured on research area of 27.6% with production loss up to 11.89%. This research showed that estimation of yield loss due to incident of extreme weather could be conducted in the level of field based on area of coverage and degree of lodging. Application of the model on wider area needs further evaluation. Keywords: Agronomic character, extreme weather adaptation, modelling, lodging, rice variety

Abstract

Study on the effect of dose management on water irrigation and the effect of pruning corn lower leaves on productivity of Lamuru variety grown on dry land of dry climate area has been done. The experiment was organized at Naibonat Experimental Station, East Kupang Subdistrict, Kupang, East Nusa Tenggara, from June to October 2011. The area used was 72 × 32 m using split plot design methods, employing two treatments. The first treatment was conducted on the main plot with water irrigation dose given 100, 80, and 60% the dose control was according to the farmer’s customary. The second treatment was applied by pruning or not pruning the lower leaves at the generative phase on the determined submain plot. The result showed that dose of water irrigation of 80 and 60% gave significant effect on corn productivity, that is 7.3 and 5.3 ton/ha, but not significant to the control (6.6 ton/ha). On the other hand, the treatment with and without leaf pruning did not give significant effect on the growth component because pruning was conducted during the generative phase. The Anova test result of corn productivity was not significantly different between the treatment of with and without pruning. The treatment of 80% dose of water irrigation could save water until 842 m3 or 20% per planting season per hectare. Meanwhile, the farmer’s customary wasted the water up to 2.105 m3 or 50% per planting season per hectare. Based on the results, the optimizing of water irrigation interval is seven times more efficient in one planting period as compared to 14 irrigation times in one planting period.

Abstract

Rice lodging followed by flooding has negatively detriment on the production, however, scientific evident is still rare. As the incident tends to escalate as the impact of extreme weather, hence, research was conducted in order to evaluate rice production and its quality of two rice genotypes treated with lodging-flooding. The experiment was conducted at Leuwikopo Farm IPB Bogor in July-October 2016 using randomized complete block design using two factors, i.e., variety (Way Seputih and Way Apo Buru) and lodging (no lodged [bending 0-18°], lodged [lodged 38-56°], and lodged with flooded [lodged 76-90°]). Rice hill aged 85 days after transplanting was lodged for 15 days. Results showed that lodged with flooded treatment did not increase yield loss although the plant tended to have sterility 5.59-22.00% higher, grain weight 2.05-35.26% lower, and 0.88-10.66% lower value of rice to unhusked ratio. Grains from the lodged-flooded plant had a number of head rice 13.38-15.78% lower, broken rice 0-24.84% higher, and stimulated germination on 1.33-3.40% grains than lodged-without-flooded. It is important to use rice varieties with stable on milling quality to address the lodged-flooded incident.

Abstract

Teak (Tectona grandis L.f.) has been grown in Indonesia since the beginning of 14th century. Teak forests in Indonesia are found mainly on the island of Java, which cover an area of about 1 million ha (Indonesia Forest State Enterprise, 1992). Outside Java, the natural area of teak is Muna Island, Southeast Sulawesi (Simon, 1997). In some recent years, teak has been planted in some other islands of Indonesia from Sumatra to Papua mainly by private sectors and farmers. Some of these plantations are in areas that would have been considered marginal for teak growing two decades ago.This phenomenon was encouraged by relatively new perception of teak planting as a commercially profitable venture, as well as by policy and legal changes. The rotation cycle of new high-intensity teak plantations is generally between 20 and 25 years which is three to four times shorter than for older low-intensity plantations (Nair & Souvannavong, 2000). Nowadays, the government does not control its harvesting and utilization for teak grown on private land.However, information on growth response of this kind of teak to climate is very limited. The fast growth of this kind of teak needs a specific environment that could be different for the slow growing one. Its resistance to water deficit may not be as high as the slow growing one as its needs much water to cover its fast growth particularly in the early period of growth. This experiment was intended to analyze the effects of water deficit to the growth of young fast growing teak.

Abstract

Efisiensi penggunaan radiasi surya adalah nilai konversi radiasi surya menjadi energi kimia melalui proses fotosintesis. Nilai ini menunjukkan persentase berapa banyak energi radiasi yang diserap tanaman mampu diubah menjadi energi dalam bentuk kimia (Lawlor, 1993). Produksi berat kering berbagai tanaman rata-rata sekitar 1,4 g berat kering per MJ radiasi surya yang diserap tanaman atau dengan kata lain mempunyai nilai Efisiensi Konversi Energi (EKE 2,5) %. Pada tanaman kentang, dengan intensitas 2 GJ m-2 selama masa pertumbuhan 120 hari umumnya diperoleh nilai EKE 1,3 % (Jones, 1992)Sampai dengan tahun 2000 perkembangan luas panen tanaman kentang di Indonesia mencapai 73.068 ha, dengan total produksi 977.349 ton, atau produksi rata-rata per hektar berkisar 13,4 ton (BPS, 2000). Di Jawa Timur, Basuki et al. (1993) melaporkan, produktifitas 10 varietas kentang pada nilai ILD 1,26 – 3,93, berkisar 11 - 27 ton per hektar. Produksi ini apabila ditinjau dari sisi penangkapan energi surya, efisiensinya sangat rendah, karena menurut Haeder dan Beringer (1983), pada kisaran ILD tersebut semestinya dapat dihasilkan umbi kentang sekitar 20 – 50 ton per hektar. Kecenderungan hasil yang rendah ini disebabkan praktek budidaya tanaman yang kurang benar sehingga memberikan nilai konversi energi surya yang sangat tidak efisien, misalnya penggunaan jarak tanam yang terlalu lebar, penanaman tanaman pada saat musim hujan dimana banyak awan yang menghalangi radiasi surya, penanaman tanaman pada dataran tinggi yang cenderung berkabut, saat tanam tanpa memperhatikan fase pertumbuhan yang peka terhadap intensitas radiasi surya, dan lainnya. Untuk meningkatkan efisiensi penggunaan radiasi surya, berbagai cara dapat dilakukan. Sugito (1999) menyarankan beberapa cara perbaikan budidaya tanaman, diantaranya dengan mengurangi energi surya yang lolos pada pertanaman dan mengoptimalkan penggunaan energi surya yang jatuh pada kanopi tanaman, diantaranya dengan meningkatkan populasi tanaman. Haeder dan Beringer (1983) menambahkan peningkatan EKE dapat juga dilakukan dengan memilih kultivar yang berumur panjang dan pemilihan lokasi bersuhu 10 – 20 C dengan intensitas cahaya tinggi. Percobaan ini bertujuan untuk menganalisis peningkatkan efisiensi energi surya melalui pengaturan saat tanam, populasi tanaman serta penggunaan varietas yang potensial.
