Abstract

Comprehensive site-specific fertilization dose is an essential factor to increase crop production. Fertilizer dose application should be based on the nutrient content in soil and plant, type and quality of fertilizer, and the climate. This study was aimed to determine the effect of unbalanced compound fertilizer NPK 16-6-23 at various doses to rice crops’ growth and yield Inpari 30 in Bangkalan regency. This research was conducted from June to October 2016. The rice varieties were Inpari 30 planted with legowo 2: 1 row system. The study used 8 different treatments : (1) without fertilizer, (2) standard dose of 200 kg/ha Urea and 300 kg/ha NPK 15-15-15, (3) 200 kg/ha NPK 16-6-23, (4) 300 kg/ha NPK 16-6-23, (5) 400 kg/ha NPK 16-6-23, (6) 200 kg/ha Urea + 200 kg/ha NPK 16-6-23, (7) 200 kg/ha Urea + 300 kg/ha NPK 16-6-23, and (8) 100 kg/ha Urea + 400 kg/ha NPK 16-6-23. The study used a randomized complete block design with 3 replications. The parameters were observed by plant height, number of productive tillers, panicle length, number of grain per panicle, number of filled and empty grain per panicle, percentage of filled grain, 1000 seed weight, and productivity. The results showed that 200 kg/ha Urea + 300kg/ha NPK 16-6-23 produced the highest plant growth on 50 DAP (77.83 cm), a low number of empty grain (11.84), a high percentage of filled grain (90.7%), and high production (7.29 t/ha). This treatment has agronomically higher effectiveness compared to standard doses with RAE value of 196.61%. This fertilizer dose is highly recommended for farmers to increase Inpari 30 rice crops in Bangkalan.

Abstract

Usnea is a genus of lichen used as a traditional medicine in the form of herbal medicine. The people of Bogor know Usnea as kayu angin, antanan, and cecenetan. Usnea used in herbal medicine is often considered only one species, even though there are many different species. Information about the traditional use of Usnea is essential to increase the widespread use of natural resources. This study purposed to determine the types of Usnea and their use as traditional medicine by the people of Bogor city. A total of 30 respondents were interviewed using semi-structured questionnaires and personal interviews. Data were analyzed descriptively based on the results of exploration and interviews with respondents. The results showed that six species of Usnea had been used for treatment, including U. intermedia, U. esperantiana, U. hesperina, U. pectinata, U. fragilescens, and U. baileyi. Usnea is used for health herbs, after childbirth, colds, gout, and herbal mixtures in all medications

Abstract

Mikania micrantha is a wild weed that thrives in tropical areas, grows rapidly in areas with high humidity and light intensity as well as in fertile soil. Meanwhile, Indonesia's tropical climate is also a suitable habitat for the breeding of termites and wood decay fungi. This study aims to determine the bioactivity of M. micrantha leaf extract against subterranean termite, Coptotermes curvignathus (Holmgren) and wood decaying fungus, Schizopyllum commune and its optimal extract concentration to prevent termite attack and inhibit fungal growth. The extracts were obtained by drying and mashing of M. micrantha leaves. The leaf powder was sieved with a 40-60 mesh filter and macerated with methanol for 3x24 h. The maceration results were filtered and the filtrate was concentrated using a rotary evaporator. Furthermore, identification of the secondary metabolites of the extract was carried out by phytochemistry. The bioactivity test included anti-subterranean termite and wood decay fungus using Potatos Dextrose Agar (PDA) medium. The results showed that M. micrantha leaf extract affected sample weight loss, termite mortality rates and the growth of wood decay fungi. Furthermore, the concentration of M. micrantha extract was inversely proportional to the sample weight loss and directly proportional to the termite mortality rate. In addition, the concentration of M. micrantha leaf extract had a negative correlation with the growth of the decaying fungus of S. commune therefore, the concentration of the extract was directly proportional to the growth inhibition of fungus. Meanwhile, the 4% extract concentration led to the increase in termite mortality rate above 80% and inhibited fungal growth by 100%. The results suggest that the bio-efficacy data from this study may be used to develop wood protecting systems based on wild weeds which are found in tropical areas.

Abstract

The objective of this study is to establish the effect of inoculum concentration and incubation time of protease activity on pigeon pea beans fermented by Aspergillus niger. The study comprises two independent variables: the inoculum concentration of Aspergillus niger, which consists of four levels (0 mL/g; 0.2 mL/g; 0.4 mL/g, and 0.6 mL/g), and six levels of incubation time (0 h, 24 h, 48 h, 72 h, 96 h, and 120 h). The obtained data were tested using two-way analysis of variance (ANOVA) followed by an LSD test with a significance level of 5%. The results show that the inoculum concentration of Aspergillus niger and incubation time do affect the activity of the protease enzyme. The highest enzyme activity of 0.298 U/ml was obtained at an inoculum concentration of Aspergillus niger of 0.4 mL/g, with an incubation time of 96 h (P2K4).

Abstract

Ultrafine particles have been attached the attention for researchers due to their impacts on human health. Ultrafine particles can be emitted fromburning process, such as forest burning, agriculture waste burning, cigarette, etc. In this study, ultrafine particles produced by cigarette smokes hasbeen investigated as a function of smoking rate. The samples consisted of different types of Indonesia cigarette called Kretek cigarette. Thequantification of emission factors was conducted by the burning of the cigarette samples, then the smoke that was sucked with a different flow rateusing an adjustable pump. The flow rate was chosen to correspond as close as the variation of the rate that people smoke. The measurements ofultrafine concentrations were carried out using an ultrafine particle counter P-Trak TSI 8525 capable of measuring particles with the diameter in therange of 20 to 1000 nm. The results showed that the emission factor of ultrafine particles significantly depended on the smoking rate. A highersmoking rate produced higher average ultrafine particle emission factor.

Abstract

Gewang (Corypha utan Lam.), a palm species, is utilized by villagers as a source of starch in East Nusa Tenggara for daily needs. This study was to describe how local people in Nusa Tenggara produce and utilize gewang starch for their diet, particularly as a rice substitute. The starch is extracted from its trunk and consumed after being cooked with grated coconut. This dish, known as “akarbilan” or “puta’ laka”, becomes the most common food in that area during transition period. Based on our analyses, the nutrition properties of 100 gr gewang starch is composed by water 11.995%, ash 0.518%, fat 0.20%, protein 0.69%, carbohydrate 86.59%, amylose 32.726%, amylopectin 51.11%, glucomannan 12.27%, Calcium (Ca) 100.52 mg, Phosphorus (P) 136.74 mg, Iron (Fe) 3.390 mg, and Vitamin B1 0.108 mg. The results suggested that the nutrition properties of gewang starch almost similar with the sago starch. However, gewang has more prospective potency for food alternative, especially in dry land such as Timor island and adjacent regions in order to build food security in Indonesia.

Abstract

Zanthoxylum avicennae (Lam.) DC. [Karangean] is a widely distributed plant in Southeast Asia and has potential in the pharmaceutical and food flavour industry with fruits and leaves rich in essential oils. The plant materials of Z. avicennae (Lam.) DC. [Karangean] were a plant collection at Bali Botanical Garden which collected from West Nusa Tenggara, on June 15th 1993. The essential oils were extracted by hydrodistillation from fresh fruits and leaves of Z. avicennae and the phytochemical composition were analysed by Gas Chromatography-Mass Spectrometry (GC-MS). The yields of essential oils were 2.75% from fruit oil and 1% from leaf oil. Respectively, a total of 41 compounds were identified from the fruit oil and 11 compounds from the leaf oil representing 91.1% and 99.81% of the total oils composition. The major compounds of the fruit oil were 1.8-cineol (12.34%), 1-para-menthen-8-yl acetate (6.24%), l-Limonene (6.09%), Cyclopropane (5.06%), Hexane (3.84%), 3-Methyl-2-(2-methyl-2-butenyl)-furan (3,74%) and predominant compouns of the leaf oil were Estragol (87.13%), 1.8-cineol (4.28%), Trans-Anethole (3.51%), Myrtenyl Acetate (0.65%), isopiperitenone (0.62%). The highest contents of these essential oils were monoterpene and sesquiterpene and these componentshad desirable properties for use in industrial companies. Therefore, the essential oils of Z. avicennae [Karangean] from West Nusa Tenggara contained chemical compositions which had potential to be developed for various human needs.

Abstract

The bioplastic can be made from sago flour and known as sagoplast. It was widely known that for making bioplastic, the addition of acetic acid and glycerol are needed. Products that are air-dried are easy to grow fungi within a few weeks. This makes the basis for researchers to undestand more about the character and identity of the sagoplast degrading fungi. Characterization and identification were carried out by observed morphology and analyzing the 18SrDNA gene sequence of fungal isolates that had grown on the sagoplast. Fungal isolates morphology showed yellowish-orange color with white thread-like mycelia and a blackish brown mace with white thread-shaped mycelia. These characters of fungal morphology that similar with Aspergillus. The gene sequences of the fungal isolates were aligned with reference gene sequences of the fungi obtained from the Gen Bank of the National Center for Biotechnology Information (NCBI). Sequence data analysis was performed by using the Clustal X program to determine the kinship and taxonomy of the fungal isolates that able to degrade sagoplast. The result showed that two fungal isolates, DFSP.J1 and DFSP.J4, were found and demonstrated their ability for degrading sagoplast. Isolate DFSP.J1 is related to Aspergillus flavus strain PSU2 LC127086.1, while isolate DFSP.J4 is related to Aspergillus niger IFO4033 D63697.1.
