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.

Additional continuous light (photoperiod of 24 hours/day) with irradiation value of 0.61 cal/cm2/minute and illumination value of 59 lux was able to suppress the development of flowering, pod building, grain filling and the production of soybean variety Bromo, so that the sum of flowers, pods and grain production dropped and reached to null value. However, the plant height increased with remarkable measurement from normally 78.0 cm to be 193.2 cm. At the later condition the plant lodged and crept. Due to additional continuous light irradiation at value of 0.03 cal/cm2/minute with average illumination value of 17 lux, the grain production was still null ton/ha. However, the formed flowers and pods were not well developed. At very little additional continuous light irradiation at the value of 0.01 cal/cm2/minute with illumination value of 2 lux, soybean production reached only 0.72 tons/ha, which at the normal condition it was able to produce grain legumes in amount to 1.53 tons/ha. Light shading at the level of 56% could not improve the negative effect of the additional continuous light excess, so that the grain production was not much better. However, grain production was either not reduced significantly due to the light shading. It showed that the soybean is well tolerant against the shading treatment at this additional light condition. Key words : light, shading, soybean, air carbon dioxide, photoperiod

ABSTRACTIn a long life cycle of oil palm plantation, sustainable water management is mandatory because irrigation is rarely applied. In order to develop water management for sustainable palm oil production, tree-based water footprint of well-established oil palm plantation was assessed. Field data were collected from February to June 2016 in Dolok Ilir managed by PTPN IV, North Sumatera, Indonesia. Additional data were obtained from interviews on the site and the surrounding estates, reports and references. Results showed that water footprint (WF) for production of fresh fruit bunch (FFB) was 510.69 m3 tonne-1 and crude palm oil (CPO) was 517.79 m3 tonne-1. Green, blue and grey water contributed 94.78%, 0.71% and 4.50% in FFB, and 93.48%, 1.66% and 4.85% in CPO productions, respectively. All green WF was calculated basen on actual value of tree evapotranspiration, therefore, the value was mostly lower than other researchs. Low amount of blue water indicates that the oil palm tree in North Sumatera extracts low amount of ground water. On the other hand, grey water for pollution dilution of fertilizers, pesticides and herbicides were high, i.e., 15.15 m3, 4.77 m3, 3.07 m3 tonne-1 FFB, respectively. It implies that reduction of grey water should be implemented in the near future through precission farming.Keywords: CPO, Elaeis guineensis, precission farming, sustainable production, water footprint

Minapadi adalah suatu model yang dianggap sesuai untuk diterapkan di sawah, baik pada lahan yang luas ataupun terbatas selama ketersediaan air mencukupi kebutuhan padi dan ikan untuk tumbuh. Pada minapadi terdapat pengintegrasian antara perikanan dan pertanian yang mana pengintegrasian tersebut dapat meningkatkan ketersediaan pupuk dan pakan. Penelitian ini bertujuan untuk mengetahui pengurangan pupuk anorganik pada pertanian terpadu padi-ikan dengan sistem minapadi sehingga dapat meningkatkan efisiensi pemupukan. Rancangan penelitian menggunakan rancangan acak kelompok faktor tunggal dengan lima taraf perlakuan, yaitu: padi monokultur 100% pupuk anorganik, monokultur ikan, minapadi dengan 100% pupuk anorganik, minapadi dengan 60% pupuk anorganik, dan minapadi dengan 20% pupuk anorganik. Minapadi dapat mengurangi penggunaan pupuk anorganik melalui hubungan komplementer antara padi dan ikan. Pemberian pupuk anorganik 20% dosis anjuran pada minapadi menghasilkan produktivitas padi tidak berbeda nyata dengan minapadi 60% dan 100% dosis anjuran dan dengan padi monokultur 100% dosis anjuran. Minapadi dapat menghemat 80% pupuk anorganik sehingga meningkatkan efisiensi penggunaan pupuk anorganik. Kelangsungan hidup ikan dan berat ikan pada minapadi tidak berbeda nyata dengan monokultur ikan. Kata kunci: monokultur, produktivitas, pupuk anorganik, unsur hara

Jejak lahan merupakan salah satu indikator untuk mengukur daya dukung lingkungan suatu sistem pertanian berkelanjutan. Penelitian bertujuan mengevaluasi daya dukung lingkungan sistem pertanian terpadu dan ternak melalui pendekatan jejak lahan dalam rangka membangun usaha pertanian berkelanjutan. Penelitian dilakukan pada Mei-Agustus 2019 di Desa Sekaran, Bojonegoro, Jawa Timur. Data indeks ketersediaan pangan (IKP) dan indeks daya dukung pakan (IDD) diformulasikan dari laporan dan wawancara. Hasil menunjukkan IKP dan IDD tahunan dalam katagori cukup dengan nilai 3.4 dan 7.2. Jejak lahan pangan adalah 143.2 ha dan jejak lahan pakan adalah 759.1 ha yang mencakup jejak lahan pakan asal limbah pertanian tanaman pangan dan hijauan. Nilai jejak lahan total pangan-pakan yakni 759.1 ha lebih rendah daripada luas lahan tersedia untuk kegiatan agronomi yakni 1,574 ha, yang mengindikasikan kecukupan daya dukung lingkungan untuk membangun sistem pertanian berkelanjutan. Namun demikian, pada April-Mei nilai IDD < 1 yang berarti ada keterbatasan pakan untuk mendukung populasi ternak yang ada. Berdasarkan nilai IDD bulanan, populasi sapi pembibitan yang dapat ditopang adalah 713 ekor dan sapi penggemukan sebanyak 24 ekor. Populasi sapi penggemukan dapat ditingkatkan hingga 1,590-2,515 ekor dengan menambah ketersediaan pakan melalui pembuatan silase, penanaman rumput gajah dan tanaman hijauan lain yang tahan kering.

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.

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.

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.

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.
