Calabash (Crescentia cujete) is a plant that grows in tropical climates and is scattered and easily found in Indonesia. Calabash is also known to contain several secondary metabolite compounds that have the potential as an antioxidant. This research is purposed to identify phytochemical compounds in calabash fruit seed extract, identify compounds b...

Keberadaan tanaman mayang di daerah Maluku Tengah cukup banyak. Pada umumnya masyarakat setempat memanfaatkan tanaman mayang hanya sebagai bahan baku pembuatan minuman tradisional beralkohol yang dikenal dengan nama sopi. Alkohol yang terkandung dalam minuman sopi tersebut dapat ditingkatkan kadar alkoholnya dengan cara redestilasi, sehingga dapat...

Maluku memiliki banyak potensi sumber daya alam khususnya dalam bidang pertanian seperti tanaman perkebunan. Salah satu tanaman perkebunan palawija yang memiliki arti strategi bagi bangsa Indonesia adalah kelapa (Cocos Nucifera L.). Masyarakat Maluku selama ini komoditas kelapa baru sebatas dimanfaatkan pada produk primernya saja dalam bentuk kelap...

Activated carbon is a cheap carbon material with high specific surface area, porosity, and electrical conductivity. This fact makes the various applications of activated carbon as an adsorbent, water treatment, and energy sector. Activated carbon dispersion studies facilitate the application of activated carbon as a primary material in the design o...

Tanaman rempah yang terkenal dari daerah Maluku di antaranya pala, kayu putih, dan cengkeh. Kandungan senyawa kimia tanaman rempah menjadikannya memiliki aroma yang khas dengan beragam manfaat serta nilai jual yang tinggi. Akan tetapi, pemanfaatan tanaman rempah sejauh ini belum maksimal terutama dari segi pendapatan masyarakat lokal. Oleh karena i...

There are two species of plant that grow flourishing all around Indonesia including in Banten and West Java which are Merremia vitifolia and Bidens pilosa. In this study we evaluate how these plants could be potentially used as natural preserver of fish product especially Auxis thazard, to inhibit the histamine formation, and to find out how this a...

In diabetics, the wound healing process occurs very slowly. Duration of diabetic wound healing can reach 12-20 weeks. Diabetic injuries that do not recover are the risk factors for infection and the leading causes of amputation and death. So far, traditional medicinal plants have been used for wound healing. One of them is kirinyuh leaves (Chromola...

An in silico study was conducted to inhibit the active compound in Kirinyuh leaves (Chromolaena odorata L.) against α-amylase and α-glucosidase enzymes using a molecular docking approach. The docking was carried out on 19 active compounds that had been identified in Kirinyuh leaves and were optimized using the PM3 method. The best results in inhibi...

Research has been carried out to test the inhibitory activity of α-amylase and glucoamylase enzymes in the ethanolic extract of kirinyuh (Chromolaena odorata L.) leaves. The use of kirinyuh leaf ethanol extract as a diabetes drug in vivo has been carried out, but its mechanism of action have never been researched before, so further research is need...

Batu Merah Village is one of the villages in Ambon City which has the largest population and also the main route of transportation access to Ambon City so that the traffic density triggers smoke pollution. This research was conducted to determine the concentration of gas CO, NO2 and SO2 on Batu Merah Village. The results of this study indicate that...

Banyak kandungan senyawa kimia bermanfaat dalam makroalga yang bernilai ekonomi tinggi tetapi belum diteliti secara luas, seperti pigmen fotosintesis. Peningkatan kebutuhan pigmen fotosintesis pada dunia industri menyebabkan pencarian sumber alternatif pigmen fotosintesis masih terus dilakukan diantaranya dari makroalga. Penelitian ini bertujuan un...

Sagu tumbuh dan berkembang sangat banyak di daerah Maluku. Sagu memiliki potensi yang paling besar untuk digunakan sebagai pengganti beras. Keuntungan sagu dibandingkan dengan sumber karbohidrat lainnya adalah tanaman sagu atau hutan sagu sudah siap dipanen bila diinginkan dan memiliki nilai kandungan gizi dan ekonomis yang tinggi namun belum dikel...

The in silico studies of interactions between the human pancreatic α-amylase (HPA) enzyme to α, β, and γ-mangostin ligands has been carried out using the molecular docking method. Ligands α, β, and γ-mangostin interacting through the formation of hydrogen and van der waals bonds to residues on the enzyme active side. The α-mangostin ligands resulti...

The research about analysis of cadmium (Cd) and lead (Pb) metal content on sediment inner part of Ambon Bay has been done. Sampling point located at 7 stations, in Dermaga Ferry Poka (S 03° 39 minute 28.2 second, E 128° 12 minute 01.3 second), PLTD Poka (S 03° 38 minute 46.6 second, E 128° 11 minute 39.8 second), Kate-kate (S 03° 38 minute 16,3 sec...
