Abstract

Oil palm plants are commodities that are mostly processed to produce CPO (Crude Palm Oil) and PKO (Palm Kernel Oil), processing plants also produce waste (by product). The highest waste produced is liquid waste (POME) around 65% and empty palm bunches around 23%. In an effort to reduce environmental pollution, the company is committed to implementing zero waste by reusing palm oil mill waste as organic fertilizer. Research with the aim to determine the effect of the application of palm oil mill effluent, empty fruit bunches, and non-application (inorganic fertilizer) was conducted at the Sungai Rungau Estate (SRGE) plantation, PT Binasawit Abadi Pratama, East Kotawaringin Regency, Central Kalimantan, from November 2023 - April 2024. The research used a survey method to describe the research site and collect primary and secondary data, with each application consisting of 3 blocks. Production data and agronomic characters obtained were then analyzed using t test at 5% level. The results revealed that the application of POME resulted in higher agronomic and production characteristics than tankos. Oil palm production in blocks applied with POME and inorganic fertilizers showed values that were not significantly different and higher than tankos application blocks, and POME application showed productivity that tended to be stable every year.

Abstract

Macronutrients (N, P, and K) are essential for plants. Plants that are deficient in any of these elements may produce less in terms of both quantity and quality. The purpose of this study is to ascertain how pakchoy (Brassica rapa L.) growth is impacted by the concentration of liquid organic fertilizer from rice washing water and NPK fertilizer. This study used a completely randomized design with two components and five treatment levels: liquid organic fertilizer treated with rice washing water (0 ml, 10 ml, 20 ml, 30 ml, and 40 ml) and NPK fertilizer treatment (0 g, 0.5 g, 1 g, 1.5 g, and 2 g). Anova was used to examine research data. The study's findings demonstrated that NPK fertilizer significantly impacted plant growth in terms of plant height, leaf area, number of leaves, and wet and dry weight. Plant height, the quantity of leaves, and plant wet weight were not significantly affected by rice-washed liquid organic fertilizer, but leaf area and dry weight were. The growth of pakchoy was not significantly impacted by the combination of liquid organic fertilizer from rice washing water and NPK fertilizer.

Abstract

Severe acute respiratory syndrome corona virus 2 (SARSCOV-2) is a virus that causes corona virus desease (Covid-19), namely a respiratory sindrome desease that comes from the beta corona virus group. A serious problem with Sarscov-2 infection is when a cytokine storm appears which is produced as the body’s response to an inflammatory reaction, but the presence of interleukin (cytokine)-10 as an anti-inflammatory cytokine can suppress inflammatory reactions to avoid cytokine storms. The study's objective was to characterize IL-10 levels in people who may have Covid-19. The research method is to use an analytical survey with a retrospective design. Interleukin-10 levels were measured utilizing the ELISA (Enzime Linked Immunosorbant Assay) method. Result: The average level of IL-10 in SARSCOV-2 utilizing the Real Time Polymerase Chain Reaction (RT-PCR) method to detect positive Covid-19 suspect samples (83.16 pg/ml) was higher than SARSCOV-2 negative Covid-19 suspects (81.03 pg/ml). Conclusion: the comparison of IL-10 levels in positive Covid-19 suspects and negative Covid-19 suspects using the RT-PCR technique has an insignificant difference in levels because naturally Pro- and anti-inflammatory cytokines' reciprocal responses show that the immune response of the samples from suspected Covid-19 patients used is still very strong (IL-10).

Abstract

The target output of white snapper (Lates calcarifer) in 2019–2024 is 10,000–14,000 tons, making it a fish type with bright prospects and economic worth for human consumption. Having access to high-quality feed is a primary aspect in promoting fish growth. Fish will grow more when intake they are give them something they can eat well enough. This will allow the fish to use the energy they get from the feed, which calls for the use of probiotics as a supplement. Probiotics are additional food (supplements) derived from living microorganisms that balance the intestinal microbial flora in the digestive tract to provide benefits to the fish that consume them. The type of probiotic commonly used is EM4 (effective microorganism 4). This study aimed to examine the effects of commercial feed supplemented with EM4 probiotics on the growth, feed efficiency, feed conversion ratio, and survival of white snapper (Lates calcarifer). The fish used in the study were white snapper with a size of 8-11 cm and a seed weight of 5±3 g which were maintained for 60 days. Feeding was done by ad satiation. Five treatments and three replications were included in the fully randomized design of this investigation. The statistics that were noted included survival, absolute weight growth, absolute length growth, feed conversion ratio (FCR), feed efficiency (EPP), and amount of feed consumed. The effects of the EM4 probiotic dose on absolute weight and length growth were demonstrated by the results. feed efficiency, and FCR in white snapper (Lates calcarifer) gave a significantly different effect, while the amount of feed consumption and survival gave an effect that was not significantly different.

Abstract

Thyroid carcinoma holds the 11th place in the incidence of new cancers, with a prevalence of 586,202 cases worldwide. The incidence of thyroid cancer in Indonesia reached 13,114 cases with 2,224 mortality in 2020. This literature review aims to provide information on thyroid cancer's clinical manifestations, diagnosis, and management. We conducted a literature searching from books, literature reviews, case studies, and guidelines from professional organizations such as the AJCC (American Joint Committee on Cancer) and European Society for Medical Oncology (ESMO) guideline. The initially noticed clinical manifestation of thyroid cancer is usually a painless lump or enlargement at the front-lower part of the neck. Diagnosis of thyroid cancer is done step-by-step from history taking, physical examination, laboratory testing of thyroid stimulating hormone and thyroglobulin, thyroid ultrasonography, and fine needle aspiration biopsy (FNAB). Management of thyroid cancer include pharmacological management, surgery, or/and radiotherapy according to the type and stage of the thyroid cancer. Early diagnosis and therapy of thyroid cancer are expected to improve the prognosis of thyroid cancer.

Abstract

Inorganic waste accumulating in plastic waste, including styrofoam, which has accumulated in large quantities in waste disposal sites (TPS), is challenging to decompose into the environment. Black beetles (Tenebrio molitor) are insects that decompose inorganic waste and can decompose polystyrene waste. The presence of bacteria in the digestion of insects contributes to the decomposition of plastic waste in the form of styrofoam. This study aimed to determine how effective the larvae of T. molitor are in degrading polystyrene waste (styrofoam) through larval development from the process of nine instar stages. In order to develop more prospective larvae, the research was conducted in multiple stages, including initial maintenance and treatment as well as data gathering to test the growth of larval length. The results are known from the length of the larval body, and it is hoped that the larvae can later be used to help decompose small to large-scale styrofoam waste discharged into the environment. Larvae of T. molitor can eat inorganic materials like styrofoam and organic ones like bran. The ability to do this is demonstrated by the growth of the larvae's weight and length, with the rise in larval length in each treatment having the most beneficial result.

Abstract

Traumatic brain injury (TBI) is a leading cause of disability and death, particularly among children and young adults, and can result in serious complications such as post-traumatic epilepsy (PTE). PTE develops after TBI and is characterized by recurrent seizures without external triggers, with the risk influenced by the location and severity of the injury. Therefore, the authors raise this topic to help improve diagnostic acuity and highlight the importance of laboratory modalities in diagnosing PTE. The literature search was conducted using Google Scholar with the keywords "Post-Traumatic Epilepsy, Biomarkers, Management, Diagnosis." Based on the inclusion and exclusion criteria, 17 publications were identified as suitable for our literature review. Diagnostic tools such as CT scans, MRIs, and EEGs are essential for assessing risk. Although antiepileptic drugs (AEDs) can reduce early seizures, they are not effective for the long-term prevention of PTE. Long-term approaches, including lamotrigine, carbamazepine, and vagus nerve stimulation (VNS), may be beneficial, but further research is needed to optimize treatment.
