“…Figure 1 shows a decrease in density as the amount of carbon increases. The highest density is shown by clay-carbon with a ratio of 100:0 which is 2243.73 kg/m 3 while the lowest density is shown by clay-carbon with a ratio of 50:50 which is 572.11 kg/m 3 . Density values that decrease along with the addition of activated carbon are also shown in research conducted [12] where the addition of 30% activated carbon will reduce density compared to the addition of 10% activated carbon.…”

“…As a result, ceramics have a very high melting point. Ceramic raw materials generally consist of kaolin, clay, feldspar, and quartz [3]. Muara Bangkahulu District is located at an altitude of approximately 20 meters above sea level with the condition of a geological unit composed of clay, conglomerates of various materials, breccias, reef limestone, tuffaceous claystone, pumice, quartz sand, and excreted wood which are part of the Bintunan formation [4].…”

Many building materials that function as insulators to maintain indoor temperature stability during hot weather have been developed. One of them is porous ceramics applied to building walls as heat absorbers. Research related to the manufacture of porous ceramics began to emerge to find the optimal composition when applied as an insulator that can absorb heat well. In general, porous ceramics use activated carbon as a pore agent. Activated carbon can be obtained by carbonating agricultural wastes such as coconut shells, hazelnut shells, rubber fruit shells, rice husks, and cocoa shells. Research continues to develop in finding the best-activated carbon base material according to the required material characteristics. Researchers will take advantage of the abundant potential of local natural resources. The method used to make porous ceramics is to mix clay and activated carbon with a clay-carbon composition ratio of 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50. The sample is made by mixing the two materials and then printed by dry pressing method with a load of 5 tons held for 10 minutes. After the sample is dried at room temperature, it is sintered at 900oC with a holding time of 3 hours. Next, the sample is characterized by determining density, porosity, and water absorption and then tested for thermal properties. After that, the surface morphology and elements in the sample are seen. The optimum composition of clay-carbon mixture is 70:30 grams. Ceramics using activated carbon from rubber fruit shells are suitable as building construction materials as heat insulators because they can absorb heat up to 500oC.

Studi ini bertujuan untik membuat tumbukan daun jambu biji untuk menghilangkan rasa sakit perut atau bisa juga disebut dengan diare. Metode ini dilakukan adalah eksperimen dan uji aktivitas katalitik secara langsung. Tahap pertama di lakukan dengan tumbukan dari daun jambu biji. Uji aktivitas langsung dengan variasi 7 helai 2 sampai 3 kali perhari selama 2 hari. Hasil eksperimen membuktikan bahwa tumbukan daun jambu biji dapat menghilangkan rasa sakit perut atau diare. Kondisi optimum tercapai pada hari ke dua. Penyembuhan ini diduga karena aktivitas katalitik ekstrak mengandung flavonoid dan tanin dalam penyembuhan terhadap usus manusia.
