Abstract

Infectious diseases caused by microorganisms are the main cause of high morbidity and mortality in the world. One of the plants that have the potential as an antiseptic is a lahuna leaf. Lahuna leaves contain active antibacterial compounds and the addition of betel leaf to the liquid soap formulations can strengthen the activity of the antiseptic produced. The purpose of this research is to test the effectiveness of liquid soap formulations of lahuna leaves and betel leaves as an antiseptic. The methods used include phytochemical screening, physical observation of liquid soap formulations, and antibacterial activity tests using agar diffusion methods. The results of the phytochemical analysis showed that lahuna leaves contain flavonoids, tannins, terpenoids, and alkaloids, while betel leaves contain flavonoids, saponins, tannins, terpenoids, and alkaloids. The liquid soap formulation of lahuna leaves and betel leaves has a clear yellow color, distinctive aroma, liquid form, rough taste, and lots of foam and has very strong inhibition against Staphylococcus aureus which is characterized by clear zones formed for each formulation I (22.4 mm), formulation II (21.8 mm) and formulation III (20.1 mm). These results indicate the potential of liquid soap formulations of lahuna leaves and betel leaves as antiseptic soap.

Abstract

This study aims to evaluate the antioxidant content and organoleptic properties of herbal tea using a mixture of secang wood and stevia leaves. The sample preparation method involves separation based on wetness level, washing, drying, and grinding to powder. Phytochemical tests showed the presence of flavonoids, saponins, alkaloids, tannins, terpenoids and steroids in both samples. The water content test shows the value is in accordance with the quality standards for packaged dry tea. Antioxidant activity was tested using the DPPH method, and the herbal wedang formulation with a proportion of 1:1 (FIII) showed the highest antioxidant activity of 76%. Organoleptic tests showed that the panelists really liked the color, aroma and taste of the FIII formulation. The overall results show that the FIII formulation is the best choice with high antioxidant content and good acceptance from consumers.

Abstract

This research was conducted to determine the characteristics of MCM-41 mesoporous silica. The mesoporous silica synthesis process used the hydrothermal method. The main ingredients used were cetyltrimethyl ammonium chloride (STAK) surfactant as a structure directing agent and ludox HS-40 as a silica source. The synthesized MCM-41 mesoporous silica was then characterized by using X-Ray Powder Diffraction (XRD) and Fourier Transform Infrared (FTIR). The XRD characterization results showed several peaks indexed with decreasing intensity, namely (100), (110) (200) and (210). This is a typical peak possessed by MCM-41 mesoporous silica. These peaks followed a hexagonal structure pattern. The FTIR spectrum showed several distinctive peaks belonging to MCM-41 mesoporous silica.

Abstract

The purpose of this study was to investigate the effect of strong and weak base activators on the adsorption properties of activated carbon derived from pineapple peel waste. Activated carbon prepared with NaOH and NH₄OH activators exhibited different physical characteristics; NaOH-activated carbon appeared darker and had a rougher texture compared to NH₄OH-activated carbon. The NaOH-activated carbon contained a moisture content of 8.2%, an ash content of 2.22%, and an iodine adsorption capacity of 393.75%. In contrast, the NH₄OH-activated carbon contained a moisture content of 9.9%, an ash content of 2.68%, and an iodine adsorption capacity of 382.41%. Atomic absorption spectrophotometry (AAS) analysis showed an adsorption capacity of 0.17 mg/L for NaOH-activated carbon and 0.18 mg/L for NH₄OH-activated carbon. Fourier Transform Infrared (FTIR) spectroscopy revealed that NaOH-activated carbon contained O–H (hydroxyl), C=C (aromatic), C–H (alkane), C–O (alcohol), and C=H (alkene) functional groups, while NH₄OH-activated carbon exhibited O–H (hydroxyl), C=C (aromatic), C–H (alkane), and C=H (alkene) groups.

Abstract

Eucalyptus sp. is one of the plant genera from the Myrtaceae family which is widely known for its diverse secondary metabolite content and high biological activity. This study aims to systematically examine the diversity of active compounds and potential bioactivity of various Eucalyptus species, especially in the leaves, bark, seeds, and essential oils. Various compounds such as 1,8-cineole, citronellal, flavonoids, and phenolic compounds have been shown to contribute to pharmacological activities such as antioxidants, antimicrobials, anti-inflammatory, immunomodulators, anticancer, as well as natural insecticides and repellents. The results of the review indicate that these activities have great relevance in the development of biopharmaceutical products, cosmetics, and other health applications. The diversity of compounds and broad pharmacological effects place Eucalyptus as a very potential source of natural materials to be developed sustainably.

Abstract

Studi ini mengeksplorasi potensi agronomi dan biokimia Melaleuca cajuputi (kayu putih) melalui tinjauan pustaka komprehensif penelitian Indonesia yang diterbitkan antara tahun 2019 dan 2024. Tujuannya adalah untuk mengevaluasi efektivitas berbagai strategi budidaya khususnya sistem agroforestri, pemupukan organik, dan perbaikan genetik dalam meningkatkan produktivitas dan kualitas minyak atsiri kayu putih. Hasil menunjukkan bahwa pola agroforestri menggunakan serai wangi ( Cymbopogon nardus ) yang ditumpangsarikan dengan varietas Sitrona 2 Agribun menghasilkan produksi minyak tertinggi (2,84%) dan kandungan 1,8-sineol (hingga 52,98%). Pemupukan organik menggunakan kompos tandan kosong kelapa sawit meningkatkan kesuburan tanah dan pertumbuhan tanaman, sementara inokulasi mikoriza arbuskular secara signifikan meningkatkan kelangsungan hidup bibit dan perkembangan daun. Lebih lanjut, varietas yang dipilih secara genetik menghasilkan 1,2–1,3% hasil minyak dengan kadar sineol mencapai 68–75%. Temuan ini menunjukkan manfaat sinergis dari praktik agronomi terpadu dan pemuliaan tanaman dalam menghasilkan minyak kayu putih berkualitas tinggi untuk aplikasi industri dan lingkungan yang berkelanjutan.
