Increasing demand on glucomannan as healthy diet in develop countries, promotes higher planting area of Amorphophallus. Iles-iles corm (Amorphophallus muellen) contains high percentage of glucomannan. In order to meet with increasing demand, providing mass planting materials is a great concern in Indonesia. Therefore, the study on skin corm and bulbil as propagation materials was conducted. In the first experiment, bulbil with different size and section, i.e., very small, small, medium and large, and half section and 1f4 section were used. In the second experiment, we evaluated the prospect of skin corm as propagul where different size of skin corm was used, i.e., 1 em x 1 em, 2 em x 2 em, and 4 em x 4 em. Results showed that both bulbil and skin corm could be utilized as prospectivepropagules of iles-iles. Propagation using bulbil was more superior as compared to skin corm. Bulbil of both whole and sectioned had high emergence of bud (> 90%), except very small sized ones. Very small bulbil (diameter less than 1 em) resulted in ca 605 of emergence. Skin corm sized 4 em x 4 em produced equal emergence to medium bulbil. In general, increasing size of skin corm increased success of emergent bud. Delaying emergence on small sized skin corm could be assessed by smaller nutrient reserved. Most unseccessemergence of small sized skin and very small bulbil was due to decay of the propagules. These experiments implied that both bulbils and skin corm could be used as mass propagules for iles-iles production.

Corm of iles-iles (Amorphophallus muelleri Blume) is extracted for glucomannan production, a material that is widely used in medicinal, food, and beverage industries. Increasing demand on glucomannan promotes fast expansion of planting area in Indonesia, however, seed availability is limited. The objective of the experiment was to study corm age, planting distance, and planting depth in order to enhance seed production in A. muelleri. Two experiments were conducted under paranet of 65% in Leuwikopo Experimental Farm, Bogor Agricultural University (IPB) from June-November 2015. First experiment used 0- (bulbils), 1-, 2-, 3-, and 4-year-old corms. Second experiment used flowering 3-year-old corms, arranged by factorial of planting distance (0 × 0 cm and 50 × 50 cm) and planting depth (0 and 5 cm in depth). Results showed that flowering of A. muelleri was dependent on corm age, 96% of 3-year-old corms produced flower but none of the 1- and 4-years-old corms produced flower, whereas 8% of 2-year-old corms produced flower. Planting distance did not affect flower growth, while planting at a depth of 5 cm enhanced seed production. Present experiments imply that application of large 3-year-old corms, planting in dense population and at depth of 5 cm could enhance seed production of A. muelleri. It needs further investigation on seed quality from flowering of present treatments.

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.

Most of Amorphophallus muelleri seeds for corm production derives from natural production in the forest. The objective of research was to evaluate seed quality and seedling growth from natural and gibberellin (GA3)-induced flowering, and different growing media in order to develop seed production technology. The experiments were conducted at Leuwikopo Experimental Farm of Bogor Agricultural University, Bogor, Indonesia from August 2016-April 2017. A. muelleri seeds from six culture practices were compared, i.e., mother corms with natural flowering were planted in soil media, soil+rice husk charcoal, and soil+cow manure, and mother corms induced flowering using GA3 (1.000, 1.500, and 2000 ppm) were planted in soil media. Results indicated that berry size, color, seed color and size and seed germination rate were independent of seed production method, i.e., non-induction, GA3 induction, and growing media. Germination rate was >90%, and no abnormal sprouting was found. The highest seedling establishment, represented by full-expand of first leaf, was obtained from seeds of soil+rice husk charcoal media. Seedling from seeds of soil+rice husk charcoal and soil+cow manure media had larger leaves than the other treatments. Present study implies that application of rice husk charcoal or manure in the seed production of A. muelleri is important to obtain high quality seedling.

Ambon Forest nutmeg (Myristica fatua Houtt) is one of the endemic plants in Indonesia. The morphological characteristic of Ambon Forest nutmeg is slightly different from that of Banda nutmeg (Myristica fragrans Houtt) i.e., it is not used as spices, but its oil is used as a lamp oil. This study aimed to determine the chemical components and essential oils of Ambon Forest nutmeg derived from its seeds, mace, and flesh compared to Banda nutmeg. Extractions of essential oils were performed using a steam hydro-distillation. Analysis of chemical compositions and contents of essential oil was carried out using a Gas Chromatography-Mass Spectrometry (GCMS) instrument and SNI 06-2388-2006 method. The essential oil contents in Ambon Forest nutmeg were relatively low, i.e., 0.63% in the seeds, 0.30% in the mace, and 0.04% in the flesh compared to Banda nutmeg i.e., 1% in the seeds, 40% in the mace, and 3.5% in the fruit flesh. The chemical compositions of essential oils showed that M. fatua Houtt contained 12 compounds in the seeds, 24 compounds in the mace, and 17 compounds in the fruit flesh, while for Banda Nutmeg, the contents of essential oils were found 18 compounds in the seeds, 10 compounds in the mace, and 15 compounds in the fruit flesh. M. fatua Houtt contained the highest Copaene, i.e., 28.41% in the seeds, 10.42% in the mace, and 23.33% in the fruit flesh. Myristicin, as the main marker compound of nutmeg oil, was also found in Ambon Forest nutmeg i.e., 1.3% in the seeds, 1.16% in the mace, and 5.19% in the fruit flesh. However, these results showed lower contents when compared to Banda nutmeg with Myristicin contents of 8.72% in the seeds, 10.14% in the mace, and 10.46% in the fruit flesh.

The increasing popularity of leaf and fruit of African nightshade as vegetables in Indonesia stimulates farmers to harvest both leaf and fruit from single plant alternately; the yield is presumably affected by fertilizer rate, e.g., nitrogen. The present study aimed to evaluate such hypothesis through evaluation of plant production, N absorption, and its status. Seedlings were treated with five N levels, i.e., 0, 90, 180, 270, and 360 kg/ha in Leuwikopo Experimental Farm, IPB Bogor, Indonesia. The results revealed that leaf and fruit productions were sensitive to nitrogen level. Leaf and fruit productions had quadratic correlation to N levels, i.e., r 2=0.9671 and r 2=0.9483 with optimum dosages as 304.8 kg/ha and 336.5 kg/ha, respectively. Proper N application is important for both leaf and fruit productions because nitrate level in leaf had quadratic relationship (r 2=0.5264) and it has a linear relationship in fruit production (r2=0.9587) by increasing N level from 90 to 360 kg N/ha. From the total fresh mass leaves and fruits harvested, the optimum N for the best alternate harvesting was 271.1 kg/ha (r 2=0.9644).

Depolarized katuk pellets (Sauropus androgynus) as a growth trigger in ruminants have been produced, but are constrained by the adequacy of leaf raw materials. This study aims to utilize the soft stems (BL) of the katuk plant as a substitute for leaf raw materials (D) as much as 15%, and its effect on the productvitas of rams growing. Katuk leaf pellets (100%) and pellets mixed between D (85%) and BL (15%) or DBL, were prepared through a depolarization process. The male rams (21) were divided into 7 groups, 3 heads each, with different pellet-giving treatments. The treatment was the control group, leaf pellets 5 g (D-5), 10 g (D-10), and 15 g (D-15), and also the DBL pellet group 5 g (DBL-5), 10 g (DBL-10), and 15 g (DBL-15) per head daily. Each sheep gets adequate treatment and feed for 3 months. TheDBL-15 and D-15 sheep group showed an improvement in the average percentage of growth in sheep body weight and carcass (p<0.05), which were 54% and 43%, respectively, as well as 74% and 43%, compared to the control group, which was only 46% and 40%. The application of DBL-15 pellets showed a greater percentage of fat deposits, which was 3.4% (p<0.05) than the administration of D-15 pellets, which was only 2.4% and the control group (2.1%). It was concluded that the 15% soft stem to the pellets is still very good as a substitute for the raw material of katuk leaves for the production of depolarized pellets. Keywords: carcass, depolarization, katuk, pellet, sheep
