Abstract

Knowledge is an important asset that is easily lost. This loss process has a significant impact on plantation research organizations whose research takes a long time. This research aimed to develop an ontology model for recording knowledge about oil palm varieties. In order to save knowledge, in this research nine oil palm varieties were modeled into ontology using the Web Ontology Language (OWL). Any information in oil palm varieties can be sorted and grouped into classes, object properties, data properties, or data expressions. The relationship between data in oil palm varieties can be well represented using ontology. Based on the results from HermiT reasoners, the ontologies with 43 classes are consistent. Information in the ontology of oil palm varieties can be easily rediscovered using the description logic query (DL-Query). The model produced from this research can be used as an initial model in designing knowledge management systems and ontology-based oil palm expert systems.Keywords: ontology, OWL, oil palm seed, knowledge management

Abstract

Mentawai Islands Regency is an area in West Sumatra with its main commodity of copra. Copra produced by farmers is sold to several collectors and copra is carried outside the Mentawai for further processing by other parties. This research recommends the government to establish a copra-based agroindustry unit and bring greater added value to the Mentawai people. For this purpose, the establishment of an agro-industry consisting of copra processing plants and a major copra warehouse was proposed. This main warehouse supplyis derived from warehouses that exist on every major island in the Mentawai Islands regency. Copra produced by farmers will be directly purchased and stored in copra warehouses on each island and then sent to the main warehouse and then subsequentlyprocessed at the copra processing plant. The proposal to determine the location of the agro-industry was decided by considering the logistical costs incurred for the delivery of raw materials to the main warehouse along the copra supply chain flow which included the cost of savings and shipping costs. Location selection was carried out with a dynamic system approach due complex inter-island supply systems with copra supply values depend on the time function. Dynamic system simulation was carried out with three scenarios of agroindustry locations, namely Siberut, South Sipora, and Sikakap Island. Simulation results showed that the establishment of the main factory and warehouse was established on Sipora Island because it generates the lowest total logistics costs.Keywords: location determination, copra, mentawai, simulation, logistic

Abstract

One of the main problem in palm plantations during the rejuvenations is the utilization of palm oil waste especially the palm trunks that reaching 220 m3/hectare. Based on that reason, we need a method of utilizing it that can increase the value from palm oil waste, not just for the benefits of oil palm farmers but also for the environment. Palm oil waste has the potential to become the raw material for making organic fertilizer (compost), it has a high nutrient content and can improve the quality of the fertilizer produced. The objective of this research was to produce a bio-fertilizer with a high quality based on the proper standards. This research was conducted in two stages including the produce of  local microorganism (MOL) from banana stem and the composting stage. The composition of local microorganism materials was banana stem: cattle urine: coconut water: brown sugar with the raio of  2: 1: 1: 1. The composting stage was started after all materials were chopped and stirred together before it composted for one month by varying between the main materials and additional ingredients. The compositions of the palm trunks as the main ingredient were divided in five variations, i.e. 3, 6, 9, 12, and 15% (w/w/), this variations were composted together with two types of additional ingredients of POME and goat manure. Based on the results of the compost analysis, the best composition was the variables of palm trunks: pome: rice husk: ash = 3: 10: 2: 1 with the results of analysis were water content of 16.30%, total NPK of 6.08% , c-organic content of 44.10% , the ratio C/N of 16.30 and pH of 8.16 and it had been fitted with bio-fertilizer standard (Permentan No. 70/Permentan/SR. 140/10/2011).Keywords: palm oil replantation, bio fertilizer, palm oil trunks, decomposer, local microorganism

Abstract

Cancer is still an epidemiological disease in Indonesia. Drug development against cancer still relies to pharmacological laboratories and natural chemicals, which could have side effects. Cancer drug development has entered the stage of molecular biology, where the interaction of ligand chemical structure with receptor protein can be studied with high accuracy. Various chemical compounds, ranging from synthetic, semi-synthetic, to natural materials, developed for the purpose to fight one of the most dangerous diseases. In the context of the development of herbal-based drugs, there has been found heaps of natural compounds, curated and annotated, in various databases belonging to China, Taiwan, Indonesia, Japan, and several other countries. However, problems arise when choosing the best bioactive compounds to develop against cancer. Complexity arises because the metabolic pathway of cancer is very diverse, depending on the type and phase of cancer. Therefore, in this systematic review, we developed a machine learning approach to screen for these bioactive compounds, then took the best candidates for molecular simulation operations that would be tested for validity in wet experiments. Thus, the automation of the candidate drug development process for cancer could be achieved with great significance. It is known that the most effective and efficient machine learning method was Naïve Bayes, but the best in processing large amounts of compound data was classfier SVM. The future of complex bioactive compounds data could be secured by employing deep learning method.

Abstract

Bio-filtration technology is considered as one of prevention solutions for declining raw water quality. The research purpose was to identify biofilm growth formation as viability cell in acclimatization period that can be used for ammonia elimination by using various indigenous chemo-heterotroph bacteria isolated from bio-filter media specimen and moving bed bio-filter reactor performance. Reactor was configured within aerobic system comparing two biofilm–attached support–medium filters (i.e. drinking-water-bottle-PET-chips and PVC). Bacteria potency on ammonia removal in kinetics modeling was advance investigated. Kinetics determination was based on empirical approach in first order by using formula of Cout = Cin exp(-k.EBRT), where Cout is ammonia concentration in outlet, Cin is ammonia concentration in inlet, k is first-order reaction rate constant and Empty Bed Retention Time (EBRT) can be formulated about setting comparison the discharge ammonia load (Q) and volume reactor (V). Total thirteen potential biofilm bacterias were successfully isolated in 24–hours–incubation at 37oC and by using Bergey’s method successfully identified prime biofilm isolates of Bacillus sp and Pseudomonas sp, then re-selected to determine one with the best ammonia removal ability. The ammonia removal kinetics constant of each reactor was obtained as followed: (1) kPET =0.421h-1(ɳ = 62.47%-NH3) and (2) kPVC = 0.412 h-1(ɳ = 58.80%-NH3).Keywords:ammonia removal, biofilm viability, bio-filtration, raw water, polyethylene terephthalate chips

Abstract

Leachate is a waste water formed from the disposed garbage in landfill site. Leachate has a high content of ammonium that can contaminate water. Ammonium removal can be done by struvite precipitation. Struvite precipitation is a process of precipitation by chemical reactions assisted with precipitant chemicals containing Mg2+ and PO43- forming a precipitate of struvite crystals (MgNH4PO4.6H2O). This study aimed to determine the effect of molar ratio and pH on ammonium removal and other important pollutants from leachate. The leachate used for the experiments was taken from landfill Galuga, Bogor Regency that is used for disposal of municipal solid wastes from Bogor City and its surroundings. MgCl2.6H2O and Na2HPO4.2H2O were used as precipitants. The process was conducted in a jar test with stirring speed of 120 rpm for 15 minutes with sedimentation time of 45 minutes. Results showed that this process could reduce ammonium concentration as well as other important pollutant levels, such as COD, TSS, turbidity, and colour. The best ammonium removal efficiency was obtained at molar ratio of 1: 1.3: 1.2 and pH 9 with an ammonium removal of 80.51%. In this condition, removals of 46.67% COD, TSS 96.04%, turbidity 86.1%, and colour of 86.43% were achieved.Keywords: Ammonium, leachate, molar ratio, precipitation, struvite

Abstract

Natural polymer-based nanohydrogel, like starches, promises superior properties such as more eco-friendly, and cheaper prices because their raw materials are available naturally in abundant quantities compared to synthetic polymers. To obtain synthetic approaching characteristics, natural polymers need to be modified to improve their mechanical stability. Research has been conducted to develop the hydrogel prepared from acid hydrolysed starch for 2 hours and 24 hours. The process of synthesising nanoparticles from hydrolyzed tapioca starch was done through the precipitation of ethanol. Synthesis of nanohydrogel was conducted by crosslinking methods using epichlorohydrin (Ech.) 5, 10, and 20%. Result showed that the particle size of tapioca nanohydrogel ranging from 14.97 – 492.7 nm. The most optimum treatment was nanohidrogel resulted from 2 hours hydrolyzed tapioca with 5% Ech. concentration, resulting swelling power, gel fraction, and texture of  357.02 %, 77,71 %, and 5.61 mJ, respectively. Nanohydrogel is promising material as carrier matrix for agrochemical as well as fertilizer. Keywords : epichlorohydrin, nanohydrogel, tapioca
