Effects of Leaf Storage and Distillation Time on the Quality of Eucalyptus (Eucalyptus grandis) Essential Oil

Essential oils such as eucalyptus oil are widely used as antioxidants, antimicrobial, anti-inflammatory, fragrance, and other medical needs. This oil is extracted from eucalyptus terpenoid compounds, e.g., cineole. This study aims to evaluate the effect of the leaf storage time and distillation time (DT) on Eucalyptus grandis essential oil yield and quality. Three DT treatments (i.e., 2 h, 3 h, and 4 h) and storage time of eucalyptus leaf in warehouse (i.e., 2 h, 3 h, and 4 h) were applied on eucalyptus leaf samples. The quality of the eucalyptus essential oil was determined using cineole…

Autosterilization Effect of Gamma Radiation in Non-sterile Radiopharmaceuticals

Gamma radiation is commonly used in sterilizing various products because of its microbial-killing property. Several radiopharmaceuticals are processed aseptically, which requires a well-managed GMP-based facility. This study aims to ensure that radiopharmaceutical can behave as an auto sterilizing agent since it contains radionuclide that emits gamma radiation. Sm-153-ethylenediaminetetramethylenephosphonate (Sm-153-EDTMP) and I-131-Hippuran were used as models in this study, in which various radioactivities of these products were added into non-sterile vials in the non-aseptic working area…

Wheatgrass microgreen with high antioxidants content in an urban indoor farming system

Urban lifestyle is identical to stressful life and sedentary habit, leading to the increase of chronic conditions such as diabetes and cardiovascular-related diseases. Antioxidants are renowned for maintaining cellular function by quenching radicals produced in stressful conditions or infection. Fresh fruits and vegetables are the primary sources of antioxidants, but the long postharvest and transport system may reduce the benefits for the urban population. Hence, we designed a cultivation method to produce wheatgrass microgreens with high antioxidants in an urban indoor farming system.…

Heterologous Production of Human Papillomavirus L1 Capsid Protein: Systematic Review and Meta-analysis

The coverage of HPV vaccination in Indonesia remains low due to the high-cost vaccination. The vaccine prices were affected by the production rate of L1, the active substance of HPV vaccines. L1 has been produced using various organisms with varying L1 production rates and immunogenicity. A systematic review and meta-analysis were conducted to determine the organism producing L1 with the highest production, treatments affecting the L1 expression rate, and immunogenicity (represented by anti-L1 IgG titer in mice). The data of L1 titer, induction period, and IgG titer were extracted from 19…

Preliminary Economic Potential Evaluation of Seaweed Gracilaria sp. Biomass Waste as Bioindustry Feedstock Through a Biorefinery Approach: A Case Study in Karawang, Indonesia

Seaweed processing usually produces biomass waste from unused and rejected materials, which have economic potential due to their bioactive components. This preliminary study aims to evaluate the economic potential of seaweed biomass waste through a biorefinery approach. Seaweed Gracilaria sp. biomass waste samples were collected from a representative seaweed production unit in Karawang, Indonesia, and their biochemical composition was analyzed. Relevant information related to seaweed biomass waste was gathered. The preliminary economic evaluation was assessed from the gross revenue of the…

Correlation of Microclimate of West Java on Caffeine and Chlorogenic acid in Coffea canephora var. robusta

Caffeine and chlorogenic acid (CGA) are two compounds that play a role in determining the quality of coffee. The amount of the two compounds may vary depending on the environment where they are grown. This study aimed to determine the correlation between the local microclimatic condition and the concentration of caffeine and CGA in green and roasted beans of Robusta coffee from six different cultivation areas in West Java, Indonesia (i.e., Ciamis, Tasikmalaya, Sumedang, Kuningan, Cianjur, and Bogor). Samples of green beans and roasted beans were extracted with 70% methanol for caffeine…

Estimation of Minimum Viable Population of Long-tailed Macaques (Macaca fascicularis Raffles 1821) in Support of Wildlife Management in Ir. H. Djuanda Grand Forest Park

Most long-tailed macaques (LTMs) in Southeast Asia are commensal animals, which means they can coexist and benefit from humans. This interaction potentially triggers disturbance and disease transmission caused by LTMs, for instance, in Ir. Djuanda Grand Forest Park (GFP). A previous study indicates an overpopulation of LTMs in this area. The need for population control of this macaque requires appropriate ecological considerations, including determining the minimum viable population (MVP). This study aims to estimate the MVP of LTMs in Ir. Djuanda GFP area is the key input for its population…
