Profil Stabilitas Fisika Kimia Masker Gel Peel-off Ekstrak Kulit Buah Manggis (Garcinia Mangostana L.)
Ekstrak kulit buah manggis (Garcinia mangostana L.) kaya akan kandungan xanton yang diketahui bersifat sebagai antioksidan. Pada penelitian sebelumnya, telah dilakukan optimasi formula masker gel peel-off ekstrak kulit buah manggis. Namun, formula optimal yang diperoleh belum tentu memiliki stabilitas yang baik selama penyimpanan. Berdasarkan hal tersebut maka dilakukan penelitian untuk mengetahui profil stabilitas fisik masker gel peel-off ekstrak kulit buah manggis dengan HPMC sebagai gelling agent. Penelitian ini diawali dengan mengumpulkan simplisia, ekstraksi, standarisasi ekstrak, fomulasi dan penetapan profil stabilitas fisika kimia. Simplisia diekstraksi menggunakan etanol 96% kemudian diformulasi menjadi sediaan masker gel peel-off lalu ditetapkan profil stabilitas fisika (organoleptis, homogenitas, viskositas, daya sebar, daya lekat, sineresis) dan kimia (pH) dari masker gel peel off ekstrak kulit buah manggis. Profil stabilitas sediaan ditetapkan selama penyimpanan 28 hari pada suhu 30°C. Penetapan profil stabilitas didasarkan dengan melihat Perubahan yang terjadi dimulai dari awal formulasi hingga 28 hari penyimpanan. Hasil penelitian menunjukkan bahwa secara keseluruhan masker gel peel off ekstrak kulit buah manggis stabil selama penyimpanan 28 hari pada suhu 300C
Kekuatan Hukum Pembuktian Waarrmerken (Akta di Bawah Tangan yang Didaftarkan) di Notaris
Notary as a public official the only one authorized to make authentic act of the deeds , agreements and determination required by a general rule or by the concerned desired to be declared in an authentic document , ensure certainty the date, saveing , all along the deed was not also be assigned or excluded to the officer or others . As a public official duties and notary work not only makes authentic act but also to register and certify (waarrmerken) letters under a hand. This research is empirical nature of this research is descriptive. Data studied were the primary data (primary data) and secondary data (Secondary data). Sembung research sites in the village. Data collection techniques are literature research and interview techniques . Non probality Sampling Sampling techniques . Data analysis method is a method of qualitative analysis . Waarmerken deed made under the deed of hand function are made under the hand guarantees about the date and the signatures of the parties concerned on the evidence. Deed under the hand that has obtained waarmerken of Notaries has the force of law under these conditions, the deed under the hand that received waarmerken of notary can assist judges in terms of evidence, due to the recognition of the signature , then the contents of the deed was regarded as the agreement of the parties , because the deed under the hand the truth lies in the signature of the parties to the recognition of the signature by the parties and to those who acknowledge his signature on the letter means he also recognizes the contents of the letter that is above his signature that the certificate is a proof of perfect
Identifying priority sites for whale shark ship collision management globally
The expansion of the world's merchant fleet poses a great threat to the ocean's biodiversity. Collisions between ships and marine megafauna can have population-level consequences for vulnerable species. The Endangered whale shark (Rhincodon typus) shares a circumglobal distribution with this expanding fleet and tracking of movement pathways has shown that large vessel collisions pose a major threat to the species. However, it is not yet known whether they are also at risk within aggregation sites, where up to 400 individuals can gather to feed on seasonal bursts of planktonic productivity. These "constellation" sites are of significant ecological, socio-economic and cultural value. Here, through expert elicitation, we gathered information from most known constellation sites for this species across the world (>50 constellations and >13,000 individual whale sharks). We defined the spatial boundaries of these sites and their overlap with shipping traffic. Sites were then ranked based on relative levels of potential collision danger posed to whale sharks in the area. Our results showed that researchers and resource managers may underestimate the threat posed by large ship collisions due to a lack of direct evidence, such as injuries or witness accounts, which are available for other, sub-lethal threat categories. We found that constellations in the Arabian Sea and adjacent waters, the Gulf of Mexico, the Gulf of California, and Southeast and East Asia, had the greatest level of collision threat. We also identified 39 sites where peaks in shipping activity coincided with peak seasonal occurrences of whale sharks, sometimes across several months. Simulated collision mitigation options estimated potentially minimal impact to industry, as most whale shark core habitat areas were small. Given the threat posed by vessel collisions, a coordinated, multi-national approach to mitigation is needed within priority whale shark habitats to ensure collision protection for the species
