Abstract

ABSTRACTThe research was conducted from October 2017 to February 2018. The experimental material used in the research was Talas Kimpul. The research was factorial in the form of randomized block design. The aim of the study was to determine whether the treatment of pruning and different harvesting time the glycemic index value in Talas Kimpul. The treatments of leave pruning in this study consisted of; without pruning, pruning by leaving 4 leaves, and pruning by leaving 6 leaves. On the other hand, the harvest times treatment is on 6 months, 7 months, and 8 months. 9 respondents were tested for blood glucose. Fasting blood glucose examination results, 30, 60, 90, and 120 minutes after subjects consumed reference food (pure glucose) and test food (boiled taro from each treatment). Each treatment was given a span of 2 days to avoid bias from each food tested. The results showed that the glycemic index value of Talas Kimpul did not depend on the pruning and harvest times.

Abstract

ABSTRACTRice processed from paddy is the main food of Indonesian people in general.Jayawijaya regency is a place that is located in Pegunungan Tengah, Papua Province, can only be connected to the other regencies through air transportation. Rice that is supplied to this regency are varied by quality and brands. Because of those rice supplying condition to this region, automatically, those various rice will be put in storage by both seller and consumer. However, keeping those rice will cause the emergence of pest, in this case, rice lice. Therefore, the purpose of this research was to find out the influence of different types of rice: organic rice, betet rice, and bulog rice to the population of rice lice pest (Sitophilus oryzae) and the rice quality by its storage period in Jayawijaya Regency. This research was conducted in Plant Conservation Laboratory of STIPER Petra Baliem Wamena. This research was conducted for six months which was started June to December 2017. The method of this research was experiment method, and the used design pattern was Random Completed Design. The treatment design was one factor which was consisted of threetypes of rice. Each treatment was repeated by three repeats. The treatment was: types of rice factor: B1: organic rice; B2: betet rice; B3: bulog rice. In this research, there were three treatments, and three repeats so there were nine experiment units. Each unit consisted of packed rice in 0.5 kg plastic for 10 plastics. In each experiment unit, three plastic were taken as samples, so there were 27 rice samples in total. According to the result of the research, we can conclude that bulog rice was able to produce more rice lice (Sitophilus oryzae) and had higher damaging percentage, however, had lesser water and glucose level compared to betet and organic rice.

Abstract

ABSTRACTThe toxicity of Al, Fe, and Mn is highly determined by the shape of the metalfractions. Therefore, the specific forms of Al, Fe, and Mn inside the soil are veryimportant to know because they are related to soil fertility. The purpose of this study was to determine the distribution of the Al fraction on the acid soil profile of dry land in Lebak Regency, Banten Province. This research was conducted from April to June 2019 in Maja District, Lebak Regency, Banten. The research was descriptive explorative with intentional sampling for special purposive sampling. The soil was tested with a main parameter using single extraction for Al Fractionation. The results showed that the Al fraction in amorphous form (Al-o) was more dominant than Al in dissolved form (Al-dd) in all horizon layers (0-120 cm). Moreover, the Al fraction in organic amorphous form (Al-p) was also more dominant than Al in the inorganic amorphous form (Al-po) at horizon layer of 0-15 cm, while at horizon laeyer of 15-120 cm the Al-po form was higher than Al-p. Al fraction in the form of organic amorphous had higher bond compared with Al form of organic amorphous in the soil layer of 0-120 cm.

Abstract

ABSTRACTKnowledge of good fertilization for oil palm on smallholder farmers is still limited.The availability of fertilizer knowledge both from primary sources and in theliterature as a secondary source, does not make it easy for farmers. An expert system is built in the form of a mobile application to implement the available knowledge base to provide fertilizer recommendations. The oil palm fertilization expert system in this research is called SmartFerti. SmartFerti is developed with a reasoning approach using a forward chaining method. The application design is based on the type of nutrients, planting density (stand per hectare, SPH), land area, type of fertilizer, and location. SmartFerti was built using 8 knowledge bases collected from reputable sources which were processed to obtain conclusions. SmartFerti provides fertilizer recommendations which include doses per semester and application time for 11 provinces in Indonesia. Nutrients that can be recommended include nitrogen, phosphorus, potassium, calcium, and magnesium. SmartFerti fertilization expert system uses an android-based interface built using App Inventor 2,0 (www,appinventor,mit,edu).

Abstract

ABSTRACTAnoectochilus formosanus is one species of Orchids, known as a “Jewel Orchids”and have been used as a folk medicine in China and Taiwan.The aim of this studywas to examine the response of using different types of explants and combination of growth regulators TDZ and BAP to morphogenesis of Anoectochilus formosanus Orchids by in vitro. The results showed that using different types of explants had very significant effect to the percentage of callus and shoot morphogenesis on 12 weeks after planting, the number of adventitious buds, adventitious shoot length, and callus diameter on three weeks until 12 weeks after planting. The best explant to callus morphogenesis was showing on shoot tip explant (50%) and to shoot morphogenesis was showing on auxillary buds and internode explant (100%). The best number of adventitious buds was observed in second internode explant with average number of shoots are 7.62 shoots. The best adventititous length was observed in axillary buds explant with average number of shoot length in 1.16 cm, and the best callus diameter was observed in shoot tip explant with average of diameter in 2.2 mm. The combination of plant growth regulator TDZ and BAP had a very significant effect to adventitious length on 10 weeks after planting, and a significant effect to adventitious length on 11 and 12 weeks after planting. The best adventitious length was observed on 0.25 mg L-1 TDZ + 0.75 mg L-1 BAP in 1.13 cm per explant on 12 weeks after planting. The best combination to callus and shoot morphogenesis was observed on 0.75 mg L-1 TDZ + 0.25 mg L-1 BAP. There was no interaction between used a different types of explant and combination plant growth regulator to morphogenesis Anoectochilus formosanus orchids by in vitro.

Abstract

ABSTRACTCocoa (Theobroma cacao L.) is one of the large plantations after oil palm. Theincrease in cocoa nursery can be accompanied by the utilization of waste derivedfrom palm oil, namely oil palm empty fruit bunches (OPEFB). oil palm emptyfruit bunches can be useful as organic fertilizer because it can improve soilphysical, chemical and biological properties. The use of OPEFB as organic fertilizer will also reduce excessive use of NPK. Utilization of OPEFB into organic fertilizer can be in the form of compost or raw OPEFB organic matter plus cellulolytic and lignolytic microbes. This study aims to determine the effectof NPK fertilizer and OPEFB compost on the growth of cocoa seedlings. Thisresearch was conducted experimentally using a completely randomized designconsisting of nine treatments and three replications. Parameters of observationwere plant height, stem diameter, number of leaves, root canopy ratio, dry weight of seedlings and age of planting. The results showed that the provision of 100 g polybag-1 OPEFB compost plus 50% NPK fertilizer (2 g polybag-1) could provide good growth in cocoa seeds (Theobroma cacao L.).

Abstract

ABSTRACTNutrients are an important factor in the cultivation of chrysanthemum cut plants.Availability of nutrients is needed during plant growth and in increasing cropproduction, therefore the addition of nutrients in the form of fertilizer is needed by cut chrysanthemum plants. The use of effective and efficient fertilizers is an indicator in the growth of chrysanthemum cut plants. The purpose of this research was to determine the optimal doses of cattle manure and biourine concentration for the growth of chrysanthemum cut plants. This research was designed with a Randomized Complete Block Design consisting of two factors. The first factor is cattle manure dose which consists of three levels, namely 2 kg per m2 (K1), 3 kg per m2 (K2), and 4 kg per m2 (K3). The second factor is the concentration of biourine which consists of 4 levels, namely 0 ml L-1 of water (B1), 250 ml L-1 of water (B2), 500 ml L-1 of water (B3), and 750 ml L-1 of water (B4). All treatments were repeated 4 times, so that a combination of 48 plots was obtained. Observation parameters included plant height, number ofleaves, stem diameter, leaf length, leaf width, chlorophyll number, flower initiation, flower diameter, flower stem diameter, and flower stalk length. The use of cattle manure at a dose of 2 kg per m2 without the addition of biourine has been able to become the optimal input for the growth of chrysanthemum cut plants.
