Abstract

The purpose of this study was to evaluate the plant growth performance of top grafted young cacao cultivated in various elevations. This research was conducted from January-August 2019 in South Sulawesi and Central Sulawesi. A total of 54 plants were taken randomly from 6 locations with 3 altitudes (<300, 300-600, >600 meter above sea level, as.). The results showed that there was not significant different of plant height, stem circle, crown circle, the number of primary branches, the number of flowers, the length of horizontal and vertical roots in response to different elevations. However, the height of primary stem and leaves number of cacao from <300 m asl was significantly greater than those from either 300-600 m asl or > 600 m asl. The largest crown portion of actual biomass was found in the branches, then followed by the leaves and stem. While the highest actual root biomass was found at 10-20 cm soil depth.

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

This study aimed to investigate the effect of compost from oil palm empty fruit bunches with different ages, mulching oil palm waste, the levels of heavy metals in compost and its influence on the growth and yield of chili. Composting was assisted by the starter (PromiTM) with a dose of 0.5 kg per ton of chopped bunches. Composting treatment distinguished by the composting time namely 4, 6, 8 and 10 weeks. Mulch treatment consisted of shell, fiber and empty fruit bunch chopped. The empty fruit bunch compost had the potential to decrease the soil acidity because the pH of 7.89- 8.66. The EFBs compost contained Boron of 7.7-10.7 ppm, 12-24.8 ppm of Cuprum, 0.05 to 0.24 % of Fe, 26.5-89.7 ppm of Mn, and 9.1-10.8 ppm of Na. This compost contained heavy metal Cd and Hg. Cd was detected in amount of 0.08 to 0.25 ppm. Hg was detected in amount of 12.9-19.5 ppm. Meanwhile, Pb and As were not found. Cd did not exceed the threshold. On the other hand, Hg was detected exceeding the threshold but did not affect the growth and yield of chili. Organic mulch from palm oil wastes did not significantly affect on the chili yield. Shell mulch had a negative influence on the growth and yield of chili.

Abstract

Plant spacing arrangement might benefit hill strength from the impact of strong wind velocity during extreme weather situations. Here, a loading test to evaluate rice hill strength was performed on Ciherang variety grown in square and double row spacing 2:1. The research was conducted at Cilubang village, Dramaga, Bogor, West Java, Indonesia from March to May 2017. Weight holding capacity was evaluated in 85 days after transplanting on four levels of hill height, i.e., 80 cm, 60 cm, 40 cm, and 20 cm above soil level with three-time replication. The results showed that double-spaced hills had 66.0 % ± 3.1 % stronger than those of square spacing at all height measurement. To lodge a hill into 20 cm to 40 cm from soil level, it required 346.7 g to 741.7 g in square spacing, and 555.2 g to 1149.2 g in double row spacing. Stronger hills in double row spacing seemed to correlate with a higher number of tiller and hills architecture; it requires further study in the role of both factors on the hill strength improvement. The present study recommends applying double row spacing to improve rice hill strength especially at a time with a high chance of lodging by strong wind incident.

Abstract

The essential oil of Banda nutmeg was extracted using hydro-distillation method to characterize their essential oil and volatile components.  Banda, Ambon, and Luhu nutmegs were chosen as sample ecotypes. Nutmeg oils were subjected to physico-chemical and GC-MC analyses.  Results indicated that nutmeg from the three ecotypes produced uncolored oils with the contents in mature seed were 11.69, 11.92, and 9.99%, respectively. Meanwhile those of immature seeds contained 13.32, 11.99, and 11.03% respectively.  Furthermore, the physico-chemical of the oil are specific gravity 0.897 to 0.909 g/ml; refraction index, 1.489 to 1.491; and optical rotation, +11.40 to +16,30.GC-MS analysis suggested that essential oils Maluku nutmegs composed of 28 to 31 components and also showed that nutmeg from Banda comprised 52.8% monoterpene hydrocarbon (MH), 21.11% oxygenated monoterpene (OM), and 18,04% aromatic compound (AC); Ambon’s 45.12% MH, 24.51% OM, and 16.97% AC; and Luhu’s 56.06% MH, 27.34% OM, and 13.62% AC.  Further analysis indicated that there were four important volatile oils fractions in nutmegs i.e. myristicin, elemicin, safrole, and eugenol. Maluku nutmeg contain 5.57 to 13.76% myristicin and 0.97 to 2.46% safrole. In conclusion, nutmeg oil shows a high stability in all physico-chemical properties.  Nutmeg from Banda ecotype has the highest content in myristicin.

Abstract

Extreme weather incidents refer to high rainfall and strong winds have been speculated to be detrimental on rice production. However, researches on the local adaptation to their impact on rice production are limited especially on tropical region like Indonesia. A study was conducted in Pesawaran, West Lampung, North Lampung, and Bandar Lampung using time series data of 2000-2015 and ground checking during extreme weather and normal seasons and its implication on sustainable management. Data were evaluated using multivariate regressions. Results demonstrated that the impact of extreme weather on the reduction of rice production was weak, 0.92%. Shifting on rice production among swampy, irrigated, and dry lands at which covered area of 13.67%, 42.69% and 43.65%, respectively, minimized the impact of the extreme weather. During limited precipitation, irrigated and swamplands had 2.5-3.0 times cropping intensity. Conversely, during La-Nina with excess precipitation, cropping in irrigated and drylands increased by 20 and 58%, respectively. Moreover, the local government maintained annual production improvement by about 5% through expansion of irrigated land, high yielding varieties and inputs subsidies. Considering that incident of extreme weathers tended to occur more frequently, consequently, planting calender utilization and rice variety adapted should be implemented.

Abstract

To mitigate the impact of extreme weather incidents, rice cultivars Way Seputih (WS) and Way Apo Buru (WAB) were evaluated under simulation of continuous wind and rainfall treatments. The research was conducted from July to October 2017 at Leuwikopo Experimental Farm, Bogor, Indonesia. For 15 days at day time, flowering rice hills were treated with about 100 mm/h water shower (Experiment-1), and with 0, 10-15, 20-25 and 35-40 km/h wind velocity (Experiment-2). Results showed that wind and rainfall treatments reduced rice production; the effect depended on the genotypes and flowering stage. Rain treatment from panicle emergence to 50%-emerged increased the number of unfilled grains by 154.6-182.3% and 55.7-101.9% in WS and WAB cultivars, respectively. Rain treatment at 100%-emerged had no effect on WS, but it increased unfilled grain (163.5%) and decreased grain index (12.9%) in the WAB cultivar. Wind speed at 35-40 km/h promoted a high percentage of grain drop (25.7%) and unfilled grains (77.3%), and low grain index (20.8 g) in WS genotype. WAB was more tolerant of wind stress than the WS. The present experiment showed that genotype had different responses to wind and rain treatments implying different mitigation strategies should be applied through genotype selection.

Abstract

Sagu merupakan salah satu tanaman penghasil pangan yang potensial dimasa yang akan datang jika dikelola dengan baik. Pada kondisi alami sagu tumbuh menyebar pada berbagai ekosistem yang luas. Sagu memiliki daya adaptasi yang kuat dikarenakan dapat tumbuh pada lahan bercekaman tinggi bagi tumbuhan lain. Tanaman sagu menyebar luas mulai dari Kawasan pesisir, rawa mineral, Daerah Aliran Sungai, dataran menengah hingga dataran tinggi. Penelitian ini bertujuan untuk mengetahui karakteristik habitat berbagai aksesi sagu dan korelasinya terhadap produksi. Penelitian menggunakan metode observasi lapang dan pengujian dilaboratorium dengan analisis data kadar lengas dengan metode gravimetri, volume dengan metode ring sampel, berat jenis dengan prinsip hukum Archimedes, tekstur tanah dengan metode pipet serta analisis kimia tanah dengan pengujian di laboratorium. Koefisien korelasi menggunakan analisis korelasi Pearson untuk melihat hubungan antara kualitas tanah dengan dengan produksi sagu dengan taraf kepercayaan 95% dengan menggunakan perangkat lunak SPSS 26. Metode pengamatan hidrologi dengan mengukur tinggi muka air tanah dengan penggalian minipit dan tinggi genangan air pada daerah yang tergenang. Tipe habitat tumbuhan sagu di Tana Luwu sangat beragam ditemukan pada kondisi lahan pesisir, rawa mineral, daerah aliran sungai, dataran menengah hingga 1000 mpdl. Rata-rata produksi terendah yaitu 181.52 kg pati kering pohon-1 terdapat pada lokasi sampel rawa pesisir dengan lama genangan 3-6 bulan dengan ketinggian 10-80 cm diatas permukaan tanah saat musim hujan dan 0-40 cm dibawah permukaan tanah saat musim kemarau. Rawa pesisir tersebut dapat dikategorikan memiliki kelas hidrologi agak baik. Aksesi sagu menyebar tidak merata pada berbagai lingkungan tumbuhnya. Sago is one of the potential food-producing plants in the future if managed properly. Under natural conditions sago grows spread over a wide range of ecosystems. Sago has strong adaptability because it can grow in high stress areas for other plants. Sago plants spread widely from coastal areas, mineral swamps, watersheds, medium to highland areas. This study aims to determine the characteristics of the habitat of various sago accessions and their correlation to production. The study used field observation methods and laboratory testing with analysis of moisture content data using the gravimetric method, volume using the sample ring method, specific gravity using the principle of Archimedes' principle, soil texture using the pipette method and soil chemical analysis using laboratory testing. The correlation coefficient used Pearson's correlation analysis to see the relationship between soil quality and sago production with a 95% level of confidence using SPSS 26 software. The hydrological observation method was by measuring the height of the groundwater by digging a minipit and the height of the puddles in the inundated areas. Habitat types for sago plants in Tana Luwu are very diverse, found in coastal land conditions, mineral swamps, watersheds, medium plains up to 1000 meters above sea level. The lowest average production, namely 181.52 kg of tree-1 dry starch, was found in coastal swamp sample locations with an inundation period of 3-6 months with a height of 10-80 cm above ground level during the rainy season and 0-40 cm below ground level during the dry season. The coastal swamp can be categorized as having a rather good hydrological class. Sago accession is spread unevenly in various growing environments.
