ABSTRAK
Fukoidan merupakan senyawa polisakarida tersulfasi yang banyak terdapat pada makhluk hidup laut terutama pada rumput laut coklat. Pemanfaatan rumput laut coklat di Indonesia belum banyak dan masih terbatas pada pemanfaatan sebagai bahan pangan. Namun sebenarnya telah banyak penelitian yang mengungkapkan manfaat fukoidan seperti antivirus, antikanker, dan lain-lain. Aktivitas imunomodulator pada fukoidan juga merupakan hal yang menarik untuk diteliti lebih lanjut, karena fukoidan telah terbukti dapat menjadi imunomodulator pada mahluk laut seperti pada udang dan ikan. Oleh karena itu dilakukan uji aktivitas imunomodulator pada tikus agar nantinya fukoidan dapat menjadi suplemen yang dapat digunakan skala besar. Mula-mula rumput laut coklat Sargassum yang telah dipotong-potong, dimaserasi dengan etanol selama 72 jam dan setelah itu disaring untuk kemudian diekstraksi. Ekstraksi menggunakan air sambil dipanaskan pada suhu 85 oC. Didapatkan rendemen ekstrak fukoidan sebesar 1,7806 . Pada ekstrak tersebut kemudian dilakukan penentuan kadar karbohidrat dan sulfat. Diperoleh kadar fukosa sebesar 22,64 dan xilosa sebesar 1,5277 serta kadar sulfat sebesar 11,882 . Pengujian aktivitas imunomodulator dilihat dari gambaran darah dan aktivitas makrofag tikus Rattus norvegicus dengan berat badan 200-250g. Fukoidan diberikan sebagai pakan pada tikus dengan cara disonde dengan 3 variasi konsentrasi yaitu 1g/kgBB, 2g/kgBB, dan 4g/kgBB. Pengujian aktivitas makrofag dilakukan dengan metode pewarnaan Giemsa. Diperoleh hasil yag optimum sebagai imunomodulator adalah pada konsentrasi 2g/kgBB.
ABSTRACT
Fucoidan is a sulfated polysaccharide compound that is widely found in marine life creatures, especially in brown seaweed. Utilization of brown seaweed in Indonesia has not been much and still limited to the utilization as food. But actually there are many studies that reveal the benefits of fucoidan such as antivirus, anticancer, and others. Immunomodulatory activity in fukoidan is also interesting to be investigated further, because fucoidan has been proven to be an immunomodulator in sea creatures such as shrimp and fish. Therefore, immunomodulatory activity test in mouse is conducted so later fukoidan can be used as supplement in large scale. At first the brown seaweed Sargassum was macerated with ethanol for 72 hours and then filtered for extracting. Extraction uses water while heated at 85 oC. Obtained rendement of fukoidan extract equal to 1,7806 . Then carbohydrate and sulfate levels of the extract was determined. Fucose content obtained by 22.64 and xylose of 1.5277 and sulfate content of 11.882 . Immunomodulatory activity assay is seen from blood and macrophage activity of Rattus norvegicus rat with weight 200 250g. Fucoidan is given by oral with 3 variation of concentration 1g kgBW, 2g kgBW, and 4g kgBW. Testing of macrophage activity was done by Giemsa staining method. Obtained optimum results as immunomodulator is at a concentration of 2g kgBW.

ABSTRACT
Neuropathic pain is nerve pain whose treatment still has side effects when used for the long term. Regulation and modulation of the immune system is needed to reduce the inflammatory reaction that triggers the onset of the pain. Immunomodulators are substances that can help regulate or modulate the bodys immune system to achieve immune balance. Ginger (Zingiber officinale Roscoe), cloves (Syzygium aromaticum L.), and nutmeg (Myristica fragrans Houtt) have been known to contain phenolic compounds that are efficacious as anti-inflammatory and immunomodulatory agents. This study aims to prove the immunomodulatory activity of neuropathic pain reducing herbs consisting of a combination of the three ingredients and to determine the effect of the type of solvent and extraction temperature on the total phenolic content of one of the herbal ingredients, which is clove. 25 Balb/c mice were divided into five groups: normal group fed and drinking, positive control was given imboost 0,39 mL/20 g BB, group dose 1 was given herbs 0,1625 mL/20 g BB, group dose 2 was given herbs 0,325 mL/20 g BW, and group 3 dose was given herbs 0,65 mL/20 g BB. After being given herbs orally for 28 days, mice were sacrificed for liver and spleen also serum protein and albumin. The administration of neuropathic pain reducing herbs showed a significant increase in total protein but the effect on serum albumin and the weight of lymphoid organs did not show significant differences compare to normal group and positive control. Treatment with herbs dose 1, dose 2, and dose 3 did not affect the histopathology of the spleen but dose 2 and dose 3 cause liver tissue abnormalities in the form of congestion. Determination of the total phenol content of clove extract was carried out using the Folin-Ciocalteu method. The results showed that the extraction temperature of 80°C with 50% ethanol solvent produced the highest total phenol content of 30,13 mg GAE/g.

Enam mencit dari masingmasing kelompok diperiksa setelah mendapat perlakuan selama dua dan empat minggu. Pada penelitian ini tidak ditemukan perbedaan yang bermakna (p>0,05) pada perbandingan perubahan jumlah leukosit, limfosit, netrofil segmen, dan jumlah IgG total antara mencit yang mendapat asupan pangan darurat BPPT dengan mencit yang mendapat asupan Phyllanthus niruri baik selama dua dan empat minggu. Oleh sebab itu, peneliti menyimpulkan bahwa produk pangan darurat BPPT memiliki efek yang sama baiknya dengan Phyllanthus niruri dalam meningkatkan respon imun mencit kelaparan dengan indikator jumlah leukosit, perubahan hitung jenis, dan jumlah IgG total setelah pemakaian dua maupun empat minggu.
ABSTRACT
BPPT emergency food is nutrient-rich cookies which are packaged in a closed session to be sent to places of natural disasters. This product contains polyphenol that has been shown to enhance immunity response in in-vitro experimentation. In order to be applicable in public life, this product needs to be experimented on animals. Experimental tests were conducted on thirty mice which were made to be hungry. After two weeks in a state of starvation, six mice were taken to be examined, while the rest were divided into two groups, one group was given BPPT emergency food and the other group was given Phyllanthus niruri, an immunomodulator which has been marketed in Indonesia. After two weeks, six mice from each group were taken for examination and the rest were examined two weeks after the first test. The result found no significant difference (p> 0.05) on changes number of leukocytes, lymphocytes, neutrophils segments, and total IgG between mice that received BPPT emergency food and mice that received Phyllanthus niruri after being treated for two and four weeks. Therefore, researchers concluded that the BPPT emergency food products has similar effect with Phyllanthus niruri in enhancing starving mice immunity response, indicated by the number of leukocytes, differential count of leukocyte, and total amount of IgG.

This research evaluated a method involving provision of a concoction of Boesenbergia pandurata, Solanum ferox dan Zingimber zerumbet extracts for pathogen prevention in tilapia. The concentration of each extract was 600 ppm of Boesenbergia pandurata/BP, 900 ppm of Solanum ferox/SF and 200 ppm of Zingimber zerumbet/ZZ. The examination was performed by issuing two combinations of extracts (SF:BP, SF:ZZ) against Aeromonas hydrophila and Pseudomonas fluorescens (105 CFUmL-1). Preventive trials were carried out by providing a concoction of extracts through intraperitoneal injection (0.1 mL/fish) in tilapia (15±2 g) and the immersion method was performed by bathing the fish in the extracts for 20 minutes, with pathogen challenging during the following 24 h being carried out. The composition of the used extract was by SF60:ZZ40; SF50:ZZ50; BP90:SF10; BP50:SF50; and fish without being given the extract. Haematology and immunology parameters were observed at the 4th week after challanges with pathogenic bacteria. The number of white blood cells (WBCs) increased significantly (P <0.05) compared to controls without extract, with a similar increase observed for red blood cell (RBCs), but heamatocrit (Ht) and hemoglobin (Hb) values did not significantly increase compared to control. Phagocytic index, respiratory burst and lysozyme activities also experienced a significant increase in fish fed with combined extracts compared to controls. The numbers of pathogenic bacteria in the body of the fish given extract were also lower than the control and significantly different at the 4th week. The results of this study indicate that giving combined extracts of SF50:ZZ50 and BP90:SF10 provides the best protection (RPS) against infection of A. hydrophila and P. fluorescent by injection of 100%. This study indicates that providing combined extracts by injection and immersion in the ratio of SF50:ZZ50 has a positive effect in increasing the non-specific immune system of tilapia and increasing protection against bacterial infections.

Latar Belakang: Radiosensitizer akan membantu radioterapi untuk memberikan inaktivasi tumor yang lebih besar. Saat ini mencari komponen radiosensitizer alami, yang diharapkan dapat memberikan efek samping yang lebih ringan daripada radiosensitizer kimia. Eucheuma cottonii yang memiliki kandungan antioksidan, memiliki efek anti tumor. Tujuan: Ulasan ini bertujuan untuk mengetahui apakah Eucheuma cottonii dapat digunakan sebagai radiosensitizer. Metode: Kami melakukan studi literatur dan menemukan 13 studi, dalam database PubMed, SCOPUS, EBSCO dan Cochrane. Studi yang dimasukkan adalah studi eksperimental yang meneliti efek Eucheuma cottonii pada sel kanker. Hasil: Uji sitotoksisitas menggunakan uji MTT dengan nilai IC50 20 μg/ml hingga 4 mg/ml, berbeda pada berbagai jenis cell line kanker. Pemeriksaan histopatologis menunjukkan karakteristik sel apoptosis. Eucheuma cottonii mempengaruhi ekspresi p53, CHK1, BIRC5, Bag1, MDM2, NFkB dan respon imun (CD4, CD8). Pemberian Eucheuma cottonii juga mengurangi pertumbuhan tumor. Kesimpulan: Telaah sistematis ini menunjukkan bahwa Eucheuma cottonii mampu menekan proliferasi, mengakibatkan kematian sel kanker. Belum diketahui apakah efek Eucheuma cottonii dan radiasi akan sinergis sehingga menyebabkan kematian sel. Tetapi jika dilihat dari pengaruh Eucheuma cottonii dengan meregulasi kontrol siklus sel yaitu terhentinya siklus sel di G2/M dan reaktivasi p53, maka ada kemungkinan Eucheuma cottonii memiliki peranan sebagai radiosensitizer. Fakta berlawanan, ekstrak Eucheuma cottonii juga mempengaruhi jalur untuk sel bertahan hidup seperti terlihatnya peningkatan NF-κB. Penelitian lebih lanjut diperlukan untuk mengeksplorasi efek sinergis dari kombinasi terapi radiasi dan Eucheuma cottonii. ......Background: Radiosensitizer will help radiotherapy to provide greater tumor inactivation. Currently searching for natural radiosensitizer components, which are expected to provide lighter side effects than chemical radiosensitizers. Eucheuma cottonii which has antioxidant content, has anti-tumor effect. Purpose: This review aims to find out whether Eucheuma cottonii can be used as a radiosensitizer. Method: We performed literatur studies and found 13 studies, in PubMed, SCOPUS, EBSCO and Cochrane databases for research the effects of Eucheuma cottonii on cancer cells. Result: Cytotoxicity test using MTT assay resulted in IC50 20 µg/ml to 4 mg/ml, differing on different types of cell lines. Histopathological examination shows the characteristics of apoptotic cells. Eucheuma cottonii involve p53, CHK1, BIRC5, Bag1, MDM2, NFkB and immun respon (CD4,CD8). Eucheuma cottonii extract also decrease tumor growth. Conclusion: This literatur review suggest that Eucheuma cottonii is able to suppress proliferation, resulting in cancer cells death. It is not yet known whether the effects of Eucheuma cottonii and radiation will be synergistic resulting cell death. But seen from the influence of Eucheuma cottonii on interfering the cell cycle control might result arrest cell cycle G2/M and reactivation of p53, it might be able as a radiosensitizer. However, it appears that there is a survival pathway such as increasing NF-κB. Further research is needed to explore the synergistic effect of a combination of radiation therapy and Eucheuma cottonii.

Abstrak :
Madu dikenal dengan aktivitas biologisnya yang beragam, salah satunya adalah sebagai imunomodulator, yakni agen yang dapat mempengaruhi respon sistem imun. Di Indonesia, salah satu jenis madu yang sudah mulai banyak diproduksi adalah madu dari nektar Acacia crassicarpa. Penelitian ini dilakukan dengan uji proliferasi sel limfosit dengan uji MTS untuk mengetahui efek penambahan madu dalam berbagai variasi konsentrasi terhadap respon sel imun, identifikasi senyawa polifenol menggunakan Liquid Chromatography Mass Spectometry (LCMS/MS), serta pengukuran kadar senyawa fenolik total dimana senyawa polifenol yang terkandung dalam madu turut diduga memiliki efek imunomodulasi bagi tubuh. Selain itu dilakukan uji fisikokimia berdasarkan standar SNI 8664:2018. Hasil pengujian menunjukkan bahwa madu Acacia crassicarpa dapat meningkatkan viabilitas sel limfosit yang terinduksi LPS hingga mencapai 90% pada variasi konsentrasi madu Acacia crassicarpa terbesar yakni 160 μg/ml. Hal ini didukung dengan temuan senyawa-senyawa fenolik dan metabolit dalam madu yang lebih banyak dibandingkan madu randu sehingga diduga dapat mempengaruhi aktivitas imunomodulasi tersebut. Madu Acacia crassicarpa asal Tanjung Jabung Barat, Jambi menunjukkan kandungan fenolik total tertinggi sebesar 494,03 ppm, yang berpotensi memiliki aktivitas biologis lebih tinggi dibandingkan madu serupa asal daerah lain. Hasil pengujian fisikokimia menunjukkan bahwa madu Acacia crassicarpa memiliki kualitas yang baik dan aman dikonsumsi, namun dengan catatan pada beberapa parameter dimana hasil uji melebihi standar yang ditetapkan yakni kadar air, kadar gula pereduksi, kadar sukrosa, dan keasaman. ......Honey is well-known for its various biological activities, one of which as an immunomodulator, which are substances that can affect the response of the immune system. In Indonesia, one type of honey that is widely cultivated recently is the Acacia crassicarpa honey. This research was conducted by testing lymphocyte cell proliferation with MTS assay to determine the effect of various concentrations on immune cell response, identification of polyphenolic compounds using Liquid Chromatography Mass Spectometry (LCMS/MS), as well as measurement of total phenolic content in which polyphenolic compounds in honey are suggested to have immunomodulation effect on human body. In addition, physicochemical tests were conducted based on the SNI 8664:2018 standard. The test results showed that Acacia crassicarpa honey able to increase the cell viability of LPS-induced lymphocytes up to 90% which is shown by honey concentration of 160 μg/ml. This result is supported by the findings of more phenolic and metabolic compounds compared to randu honey, therefore suggests these compounds may affect the immunomodulating activity. Acacia crassicarpa honey from West Tanjung Jabung, Jambi showed the highest total phenolic content of 494.03 ppm, and may have higher biological activity potential compared to similar honey from other regions. The results of physicochemical test showed that Acacia crassicarpa honey has good quality and safe for consumption, but with a note on several parameters where the test results exceeded the established standards; with those parameters being water content, reducing sugar content, sucrose content, and acidity.
