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 C out = C in exp(-k.EBRT), where C out is ammonia concentration in outlet, C in 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 37 o C 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) k PET =0.421h -1 (ɳ = 62.47%-NH 3 ) and (2) k PVC = 0.412 h -1 (ɳ = 58.80%-NH 3 ).

Struvite precipitation is a process of precipitation by chemical reactions assisted with precipitant chemicals containing Mg 2+ and PO 4 3- forming a precipitate of struvite crystals (MgNH 4 PO 4 .6H 2 O). 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. MgCl 2 .6H 2 O and Na 2 HPO 4 .2H 2 O 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.

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.

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","PeriodicalId":17735,"journal":{"name":"Jurnal Teknologi Industri Pertanian","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84020396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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 Naive Bayes, but the best in processing large amounts of compound data was classfier SVM.
