This final project discusses the dynamics of a fractional-order predator-prey system that incorporates three effects on the prey population: the Allee effect, fear effect, and shelter effect. The model under study has several equilibrium points, and their stability is analyzed based on various initial conditions and system parameters. Simulations are conducted to explore how these parame- ters …
This final project discusses the average lower 2-domination number of Jahangir graphs J2,m and J3,m. The determination of the average lower 2-domination number is done by analyzing the characteristics of the 2-domination set of these Jahangir graphs with values m = 2, 3, 4, 5 and 6. The results show the formula for the average lower 2-domination number for Jahangir graphs J2,m and J…
Final project discusses the concept of quasi-ideals in more general structures, namely seminear-rings and ternary seminear-rings. In determining quasi-ideals in seminear-rings and ternary seminear-rings, de_nitions and theorems related to the structure of seminear-rings and ternary seminear-rings and their res- pective ideal concepts are provided, as well as subseminear-rings and ternary subsem…
This final project discusses two-step iteration methods for solving nonlinear equ- ations. ALG1 method is derived by utilizing the Householder method, Taylor expansion, and Newton method as predictors. ALG2 method is a modification of ALG1 using interpolation techniques. Convergence analysis using Taylor expansion and geometric series shows that both methods have a convergence order of six with…

The optimization technique applied is integer programming with the branch-and-bound approach, which calculates decision variable values using POM QM V5 software. The research is based on completed order data, includ…
Drynaria sparsisora is an epiphytic fern species belonging to the Polypodiaceae family. Several species within this genus have been reported to exhibit anti- inflammatory, anticancer, antimicrobial, antifungal, and antiviral properties. This study aimed to isolate secondary metabolites from the chloroform extract of D. sparsisora and evaluate their antifungal activity. The chloroform extract wa…
CaO catalyst impregnated with SiO2 (silica) is a heterogeneous catalyst that is widely used in transesterification reactions for biodiesel synthesis. However, the yield of biodiesel produced is not optimal, due to the small surface area and stability of the catalyst, requiring modification with other types of metal oxides such as Fe₂O₃. Fe₂O₃ has high porosity and stability thus can inc…
Fungi are one of the promising microorganisms for the discovery of new drug candidates as antimicrobial and antioxidant compounds. One of the microorganism that is thought to be used as a producer of new antimicrobials is Penicillium sp. LBKURCC34 and LBKURCC38 from the peat soil of the primary forest of the Giam Siak Kecil Bukit Batu Biosphere Reserve (GSKBB), Riau Province. The metabolomic an…
Infections caused by pathogenic bacteria are still a public health problem in the world. Therefore, the search for sources of bioactive compounds, especially antimicrobials and antioxidants, continues along with the increasing resistance of bacteria to existing antibiotics. One of the fungi isolated from local peat soil in Riau is Penicillium sp. LBKURCC34 and LBKURCC39 which has antimicrobial …
Laccase (benzenediol: oxygen oxidoreductase, EC 1.10.3.2) is a p-diphenol: dioxygen oxidoreductase classified as a multi-copper protein and has broad substrate specificity. The potential of laccase as one of the enzymes produced from fungal isolate Trichoderma asperellum LBKURCC1 has been reported in the enzymatic degradation of several chemical compounds such as synthetic dyes.

Some studies inform that Allium cepa L. onions contain secondary metabolites that have the potential as natural antioxidants and as inhibitors to inhibit α-amylase activity. Therefore, the antioxidant potential and α-amylase inhibition of three different types of shallots, namely onions, Brebes and Solok were tested and it is suspected that these three shallots contain different secondary me…
Laccase enzyme (E.C1.10.3.2: oxygen oxidoreductase) is a multi-copper enzyme that catalyzes the oxidation process of various types of organic and inorganic compounds such as mono, di- and polyphenol compounds, aminophenols, methoxyphenols, substituted phenols, diamines, aromatic amines and ascorbic acid. Laccase is an oxidoreductase enzyme produced by various organisms, primarily fungi. This re…
Silica Catalyst (SiO2) is a heterogeneous catalyst that can be used in producing diesel precursors through hydroxyalkylation-alkylation (HAA) reactions. Silica (SiO2) as a catalyst material has a high surface area, good chemical and thermal stability, but lacks better adsorption capacity and catalytic activity, hence the addition of sulfate groups is necessary. The addition of sulfate functiona…
