Glucomannan is a polysaccharide consisting of β-1.4-linked D-mannose and D-glucose monomers, which have many benefits especially in the food and pharmaceutical industry. It has been widely reported that one of the main sources of glucomannan is porang tuber (Amorphophallus muelleri Blume). Generally, glucomannan extracted or purified from porang flour. However, the drying process causes other compounds than glucomannan stick strongly, resulting low levels of glucomannan. This study was to obtain glucomannan extract in an easy, effective, and inexpensive method, by direct extraction from fresh porang tubers using ethanol technical grade. We performed two extraction methods. The first is a fixed concentration method, the sample was repeatedly extracted using 50% ethanol (FC50) and 96% ethanol (FC96) 3 times, respectively. The second is a multilevel concentration method, the sample was repeatedly extracted using ethanol 60% (first step), 80% (second step), and 96% (third step), one replication each step. The highest glucomannan content (66.56%) was obtained by a multilevel concentration method. Moisture, lipid, protein, crude fiber, calcium oxalate level significantly reduce to 13.58%, 0.07%, 4.03%, 4.95%, 0.56% respectively. FTIR spectra confirmed the presence of functional groups (O-H, C=O, C-O, C-H), that compose the glucomannan compound. SEM image showed that the granules form of glucomannan were round and oval, began to change its phase from amorphous to crystalline, related to XRD data. The results showed that the direct extraction from fresh porang tuber using ethanol technical grade with a multilevel concentration method was an effective method to extract the glucomannan

Indonesia has a great taro diversity and had been utilized for long time. Taro has more competitiveness including high nutrition, wide adaptation, and ease for cultivation, further, it’s very potential to be the future food and create new economical value. The objective of the research was to obtain the organic manure fertilizer effect on sutra taro variety growth and yield. The research was conducted for eight months from January till August 2021 at Leuwikopo Farm, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University. A Completely Randomized Block Design (CRBD) with five replications and four-level organic manure treatments (0.25 kg, 0.5 kg, 0.75 kg, and 1.00 kg per plant) was applied. Taro growth, corm characters, and yields were affected by organic manure fertilizer dose. The dose of 0.75-1.00 kg/plant (equivalent to 15-20 ton/ha) showed the highest growth, corm characters and yields more than the lower doses. Taro “Sutra variety” cultivation by fully using organic manure fertilizers is very potential to be encouraged.

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.

Climate change as indicated by rising temperature and changing rainfall pattern has been known to affect cacao production in many production countries. However, studies on the effects of rainfall and temperature variability on the cacao production are rarely reported in Indonesia. Hence, the objective of this study is to evaluate the stability of cocoa production in relation to rainfall and temperature variability in order to develop sustainable production under climate change scenario. Research was conducted at a state owned company in Jember District, East Java, Indonesia from February to June 2015. Production and climatic data of 2010-2015 were evaluated using simple regression and correlation analysis. Results revealed that productivity fluctuated among months and among years. However, the fluctuation among months (s2 = 117.076) was lower than among years (s2 = 311.225). Rainfall and temperature showed variability among months and among years; and the fluctuation among months was lower in both rainfall and temperature. Rainfall at one to four months before harvest correlated with production (r=0.400-0.671; P= 0.000 to 0.001) and temperature at two to four months before harvest determined cocoa production (r=0.371-0.412; P=0.001-0.003). High monthly cocoa production coincided with decreasing temperature and rainfall for 4 to 5 months during pod development. The presented study implies that both short and long term strategies should be implemented under climatic variability to sustain cocoa production. It is recommended to apply production technology to stabilize micro climate temperature and to minimize the impact of high rainfall such as shade plant and canopy manipulation.

Fruits and young shoot of Solanum nigrum Linn are harvested and consumed as indigenous vegetables by different Indonesian ethnics. Preharvest factors and harvesting methods to maximize the quality of S. nigrum produce is still unknown. In this study S. nigrum was grown in full irradiance and under shading and assessed for their growth, and fruit and shoot yields. The experiment was conducted at the Leuwikopo Experimental Farm in Bogor Agricultural University, Indonesia from April-July 2017. The results demonstrated that plants produced more fruits and shoots in full irradiance, i.e., 687.9 g and 211.1 g per plant, whereas only 331.1 g and 116.9 g per plant were produced in 50% shading. Although fruit and shoot production were superior under full irradiance, shoot-harvested plants had healthier leaves and life span of about 2 months longer thus facilitating longer availability. Canopy of shoot-harvested plants formed a columnar shape with 23 to 45 cm in height, in contrast to spherical shape with 48 to 203 cm in height of the fruit-harvested plants. It is likely that shading level might contribute to farmers’ decision to harvest the shoots or fruits of S. nigrum. Further studies are needed to determine the effects of shading levels on nutritional quality of the shoots and fruits of S. nigrum.

The availability of nutrients in plants depends on the ability of plants to absorb nutrients from the soil. One of the processes absorbed by plants is by the presence of the transpiration process.Â Good transpiration will provide enough nutrients for plants which increase the productivity and quality of mangosteen. One of the quality standards of mangosteen fruit for export quality is the free from yellow sap contamination. It can be possible that transpiration can improve the quality of mangosteen fruit by applying fertilization. In this study Ca fertilization was carried out on mangosteen seeds, where this study aims to investigate the effectiveness of Ca uptake by mangosteen plants with the level of water loss by transpiration. This research was conducted in November 2016-March 2017 at the Leuwikopo Experimental Garden, Bogor Agricultural University. Morphological observations were carried out in its Experimental Garden and the Postharvest Laboratory whileanalysis of calcium content of plant tissue was done at the Department of Agronomy and Horticulture, Bogor Agricultural University. Data obtained then were analyzed using ANOVA test. If the results were significant, Duncan Multiple Range Test (DMRT) was then tested at 0.05 probability level. The results revealed that the transpiration rate of mangosteen plants from several treatments showed a significant difference, the transpiration rate was higher, especially in fertilized plants. The size of the 12th leaf, plants treated with fertilizer have a larger size than the treatment without fertilization. Fertilizing and providing enough water can maintain the growth of the plants.
