Oleh itu, dilakukan pengujian pengaruh pendinginan pada setelah proses pasteurisasi dengan alat vacuum cooling. Pada industri pengolah telah menggunakan cooling, saat melakukan vakum, terdapat masalah yaitu tersedot ke selang vakum terjadi, maka peneliti volume se...

It is shown that for a metric space (M,d) the following are equivalent: (i) M is a complete R-tree; (ii) M is hyperconvex and has unique metric segments.

We present a new spatial index belonging to R-tree family. Since our new index comes out from the R-tree and holds the concept of nonoverlapping nodes we call it R-tree. The original R-tree was designed for both point and spatial data. Using R-tree for indexing spatial data is very inefficient. In our research we face the problem of indexing product catalogues data that can be represented as po...

R-tree based access methods for moving objects are hardly applicable in practice, due mainly to excessive space requirements and high management costs. To overcome the limitations of such R-tree based access methods, we propose a new index structure called AIM (Adaptive cell-based Index for Moving objects). The AIM is a cell-based multiversion access structure adopting an overlapping technique....

Coastal lagoons are important systems for freshwater, estuarine and marine organisms; they are considered important zones of reproduction, nursery and feeding for many fish species. The present study investigates the fish assemblages of the natural reserve of Dzilam and their relationship with the hydrologic variables. A total of 6 474 individuals (81 species) were collected, contributing with ...

Bioetanol merupakan bahan bakar nabati yang dapat dijadikan sebagai alternatif untuk menggantikan fosil tidak diperbarui. Sementara buah nanas biasa dikonsumsi hanya diambil buahnya saja, sedangkan bagian kulit nya limbah dibuang begitu padahal dalam memiliki kandungan gula dan karbohidrat cukup tinggi, sehingga berpotensi dimanfaatkan baku pembuatan bioetanol. Tujuan dari penelitian agar meman...
