The experiment was conducted to evaluate the effects of spirulina on production, hematological parameters and lipid profile in layers. Thirty (30) layer birds of 65 weeks of age were randomly divided into three groups (A, B and C) containing 10 birds in each group. Birds were subjected to treatments for a period of 1 month (30 days) as per fol lowing schedule: Group-A treated with 2gm spirulina/kg feed; Group-B: treated with 4gm spirulina/kg feed and Group-C: without any treatment. With the supplementation of spirulina, feed consumption and body weight were not affected, but egg production was increased significantly. Results showed that total erythrocyte count (TEC), haemoglobin concentration and packed cell volume (PCV) were significantly higher (P<0.05) in treated groups compared to control. Serum total cholesterol (TG), triglyceride (TC)) and low density lipoprotein (LDL) cholesterol were significantly decreased, as well as HDL was increased (P<0.05) with addition of the increasing rate of spirulina supplemented groups (2gm and 4 gm.) than the control group. Overall, this work suggests that spirulina has a positive effect on egg production and explores the perspective use of spirulina improves haematological parameters and lipid profiles in layer birds.

A phytosociological study of a lowland forest was carried out at the Tesso Nilo National Park (TNNP), Riau. The objective of the study was to obtain quantitative data on the floristic composition and structure of the above-mentioned lowland forest. By establishing a plot of 1.0 ha, the quadrat method was used to collect the data. We recorded a total of 1,303 individuals of trees and saplings with diameters ≥ 2 cm, comprising 304 species, 153 genera, and 62 families. Using the dominance and density of two tree species, the forest community in the plot can be designated as Sloetia elongata-Pimelodendron griffithianum Association. The species sharing the dominance were Sloetia elongata (Importance Value, IV = 14.43), Pimelodendron griffithianum (IV = 6.17), Santiria laevigata (IV = 5.45) and Xylopia caudata (IV = 5.17). Diameter records showed that 80% of trees in the plot were dominated by small individuals with diameters between 10-30 cm. Trees with diameters 30 cm were Dracaena cf. porteri (diam. 75.6 cm), Artocarpus elasticus (63.3 cm), and Ctenolophon parviflorus (62.1 cm). Dipterocarp species was not important since they contributed only 4%, while non-dipterocarps shared 96% comprising 61 families. The highest basal area was shared by nine species, including one dipterocarp, Shorea leprosula. Several dipterocarp species occurring in TNNP have been listed in the IUCN Red List of Threatened Species, including Anisoptera megistocarpa, Hopea ferruginea, Hopea pachycarpa, Shorea atrinervosa, Shorea faguetiana, Shorea lepidota and Vatica gamosepala. The presence of a large number of small trees and a few large trees indicated that the forest in the plot was regenerating after heavy disturbances. Regenerating species were divided into five categories, in which 13 species were regenerating well with Sloetia elongata being the best regenerating species while dipterocarps were represented by Shorea acuminata. The occurrence of the majority of trees with a height of 20 m further confirmed the dynamic status of the forest. The importance of primary and secondary forests in TNNP was discussed. Restoration to the original forest was recommended by planting primary forest species, including endemic, rare, and endangered tree species.
Environmental security and resilience – Indonesia and global challenges
Authors: Monk Kathryn A. , Priatna Dolly 
Published: April 2022

Indonesia faces tremendous challenges from climate change, biodiversity loss, and wider social and economic change. These challenges need extensive interdisciplinary approaches enabling multiple perspectives from diverse stakeholders to be recognised and utilised. Collaboration between scientists, social scientists, and economists has never been so important. As Christiana Figueres, former Executive Secretary, United Nations Framework Convention on Climate Change said: “The [global] challenges we face are massive, urgent, and interconnected. We need people across all sectors to pull together and move us to a bright and strong future. There’s no time to waste!”. We are therefore happy to see the growing number of community-based participatory studies being submitted to InJAST and hope these will increase in future. There are exciting and vitally important issues to be tackled and supported by environmental managers to build the necessary environmental security and resilience, from direct conservation work to flood risk management and pollution control. Climate change drives or affects all these of course and has been, for example, one of the key drivers for Indonesia’s momentous plans to move the capital from the 256,000-hectare (990-square-mile) Jakarta on the north-western side of Java Island, the most populated island in the country, to the relatively undeveloped and biodiversity-rich East Kalimantan province on the island of Borneo. Climate change and immediate economic drivers in many parts of Indonesia also contribute to the annual toxic haze, which causes air quality to reach hazardous levels and creates major health, environmental and economic problems, especially in Sumatra and Java. Indeed, as of March this year, Riau province has already declared a state of emergency ahead of this year’s main fire season.

Korosi merupakan penurunan mutu logam akibat adanya reaksi elektrokimia dengan lingkungannya, sedangkan bio-korosi merupakan suatu peristiwa korosi yang dipengaruhi oleh mikroorganisme terutama dari kelompok Sulfat Reducing Bacteria (SRB). SRB mengakibatkan terjadinya korosi logam pada tangki penyimpanan biosolar. Laju korosi dapat diturunkan dengan cara penambahan inhibitor organik maupun anorganik ke dalam suatu media korosi. Tujuan penelitian ini adalah mempelajari pengaruh inhibitor organik berupa asam askorbat, dan inhibitor anorganik berupa natrium nitrit dan natrium fosfat terhadap terhadap laju korosi dan efisiensi inhibitor pada logam alumunium (Al) dan seng (Zn) yang direndam dalam media biosolar dalam kondisi pH asam. Pengaruh ketiga jenis inhibitor yang masing-masing memiliki konsentrasi sebesar 25, 50, dan 75 ppm terhadap logam yang direndam dengan biosolar diinvestigasi menggunakan teknik penurunan berat logam. Pengukuran berat logam yang direndam dalam inhibitor dan media biosolar dilakukan pada variasi waktu 0, 1, 4, 7, dan 10 hari kemudian dilakukan analisa laju korosi dan efisiensi inhibisi. Masing-masing inhibitor dapat mengghambat laju korosi logam dengan efisiensi inhibisi tertinggi yaitu asam askorbat. Inhibitor terbaik dalam media biosolar yaitu asam askorbat 75 ppm yang dikontakkan dengan logam selama 10 hari dengan nilai efisiensi inhibitor asam askorbat terhadap logam alumunium sebesar 26,92 % dan seng sebesar 70,90 %
Corrosion is a decrease in metal quality due to an electrochemical reaction with its environment while bio- corrosion is a corrosion event that is influenced by microorganisms, especially from the Sulfate Reducing Bacteria (SRB) group. This group of bacteria generally causes metal corrosion in biodiesel storage tanks. The corrosion rate can be reduced by adding organic or inorganic inhibitors. The purpose of this study was to study the effect of organic inhibitor such as ascorbic acid, and inorganic inhibitors such as sodium nitrite and sodium phosphate on the corrosion rate and inhibitor efficiency of aluminum and zinc metals immersed in biodiesel media under acidic pH conditions. The effect of the three types of inhibitors which each concentrations of 25, 50, and 75 ppm on metals immersed in biodiesel was investigated using weight loss techniques. The measurement of the weight of the metal immersed in the inhibitor and biodiesel media was carried out at various times of 0, 1, 4, 7, and 10 days and then calculated the corrosion rate and inhibition efficiency. The best inhibitor in biodiesel media is 75 ppm ascorbic acid which is in contact with metal for 10 days with has an efficiency value of ascorbic acid inhibitor against aluminum metal of 26,92 % and zinc of 70,90 %.

Published: April 2022

Buah pisang adalah sumber pangan yang banyak dikonsumsi karena memiliki kandungan karbohidrat yang tinggi. Bagian lain dari buah pisang yaitu bagian kulit dapat dimanfaatkan sebagai karbon aktif karena mengandung selulosa sebesar 14,4%. Karbon aktif dari kulit pisang khususnya Pisang Kepok (Musa acuminate L.) dapat digunakan sebagai zat penyerap bahan pencemar dan logam berat dari limbah industri. Pemanfaatan kulit pisang sebagai karbon aktif ini diharapkan dapat menjadi alternatif dari solusi pengolahan limbah padat organik sebagai zat penyerap logam berat dari limbah industri. Penelitian ini dilakukan untuk mengetahui kualitas dari karbon aktif dengan bahan baku kulit Pisang Kepok setelah diaktifkan menggunakan larutan basa dan asam. Karbon aktif dibuat dari kulit Pisang Kepok yang diaktivasi menggunakan aktivator basa kuat (NaOH) dan asam kuat (H2SO4) dengan konsentrasi 0,5 dan 1 N selama waktu aktivasi 1, 3, dan 5 jam. Hasil penelitian menunjukkan bahwa aktivator basa menggunakan larutan NaOH dengan konsentrasi aktivator 0,5 N selama waktu aktivasi 1 jam dapat menghasilkan karbon aktif dengan karakteristik yang sesuai dengan SII No. 0258-88. Karbon aktif yang dihasilkan dari kulit Pisang Kepok pada kondisi tersebut mampuf menurunkan kandungan logam Nikel pada larutan NiSO4 sampai 100%. Karbon aktif yang dihasilkan pada konsentrasi rendah dan waktu aktivasi yang singkat dapat mengurangi biaya produksi.

Because of their high carbohydrate content, bananas are a popular food source. The skin of a banana can be used as activated carbon because it contains 14.4 percent cellulose. Activated carbon from banana peels, specifically Pisang Kepok (Musa acuminate L.), can be used as an adsorbent for pollutants and heavy metals emitted by industrial waste. The use of banana peels as activated carbon as a heavy metal absorbent from industrial waste is expected to be an alternative solution for treating organic solid waste. The purpose of this research is to ensure that the quality of activated carbon made from banana (Musa acuminate L.) peel after it's been activated with alkaline and acid solutions. Activated carbon is generated from banana (Musa acuminate L.) peel that has been activated with 0.5 and 1 N concentrations of strong base activator (NaOH) and strong acid activator (H2SO4) over activation times of 1, 3, and 5 hours. The results indicate that an alkaline activator using NaOH solution with an activator concentration of 0.5 N for 1 hour can produce activated carbon with SII No. 0258-88- compliant properties. Under these conditions, activated carbon derived from banana (Musa acuminate L.) peel was able to reduce the nickel concentration in the NiSO4 solution by up to 100 %. Using activated carbon with low concentrations and short activation durations can minimize costs of production.

Folic Acid Levels During Pregnancy Regulate Trophoblast Invasive Behavior and the Possible Development of Preeclampsia
Authors: Rahat Beenish , Hamid Abid , Bagga Rashmi , Kaur Jyotdeep 
Published: April 2022

BackgroundOne of the unique features of placentation is its similarity to tumorigenesis yet being very well regulated. It allows rapid proliferation, migration, and invasion of mononuclear trophoblast cells into the maternal uterus and remodeling the maternal vasculature. This pseudomalignant nature of trophoblastic cells is strictly regulated and its importance becomes evident in abnormal pregnancies that are characterized by aberrant trophoblast proliferation/invasion like preeclampsia. In addition to this, the importance of folic acid supplementation during pregnancy is well documented. We aimed to analyze the molecular and epigenetic regulation of the pseudomalignant nature of placentation via folic acid levels.MethodsPlacental tissue samples were collected from different pregnancies in three different gestational stages. We estimated the impact of folic acid levels on global methylation, LINE1 methylation, and expression of DNMTs in all three gestational stages in pregnant women and preeclampsia pregnancies. We also analyzed the effect of folic acid supplementation on trophoblastic invasion using placental derived cells viz, JEG-3 and HTR-8/SVneo cell line and verified the molecular and epigenetic mechanisms involved in this regulation.ResultsDevelopment of preeclampsia was observed to be associated with lower folate levels in placental tissue, higher global methylation level, and higher expression of DNMT1and DNMT3A. Folic acid supplementation was found to increase the invasive potential of placental trophoblasts by almost two folds which were associated with the decreased expression of tumor suppressor genes and tissue inhibitors of matrix metalloproteinases; and increased expression of oncogenes, telomerase gene, and matrix metalloproteinases. These folic acid-mediated changes were observed to be regulated by CpG methylation in the case of many genes. Folic acid supplementation was also observed to significantly decrease global methylation in placental trophoblasts related to decreasing expression of DNMT1 and DNMT3A.ConclusionLower folic acid levels are associated with preeclampsia development and folic acid supplementation regulates the invasive potential of placental trophoblasts as mediated by various epigenetic changes in the placenta suggesting the protective effect of folic acid against preeclampsia.
