The type of material used in making paving blocks can affect quality. One of the materials that can be used for making paving blocks is Oil Palm Empty Bunches (OPEB). The purpose of this study was to examine physical properties (moisture content, specific gravity, specific gravity after immersion in sodium sulfate, and resistance to sodium sulfate) and to test the mechanical properties (compressive strength) of paving blocks from a mixture of OPEB waste with fine sand and cement PC. Result a good combination for paving block is treatment B which is the addition of OPEB fiber by 125 g. The water content value of treatment B is 1.43% and has the highest compressive value with a maximum load of 195 with an average of 186.667 kg and the resistance test to sodium sulfate (Na2SO4) meets SNI standards. Paving blocks combined with OPEB fibers in this study are good for home yards, parking lots or paths in city parksPenggunaan jenis materian untuk pembuatan paving block dapat mempengaruhi kualitas. Bahan yang dapat dimanfaatkan untuk pembuatan paving block salah satunya ialah Limbah Tandan Kosong Kelapa Sawit (TKKS). Tujuan dari penelitian ini adalah menguji sifat fisik (kadar air, berat jenis, berat jenis setelah perendaman dengan natrium sulfat, dan ketahanan terhadap natrium sulfat) serta menguji sifat mekanik (daya tekan) pada paving block dari campuran limbah TKKS dengan pasir halus dan semen jenis PC. Pengujian penelitian ini meliputi uji sifat fisik serta sifat mekanik. Kombinasi yang baik untuk paving block ialah perlakuan B yaitu penambahan serat TKKS sebanyak 125 g. Nilai kadar air perlakuan B yaitu 1.43 % dan memiliki nilai tekan yang tertinggi dengan beban maksimal 195 dengan rata-rata 186,667 kg serta uji ketahanan terhadap Natrium Sulfat (Na2SO4) memenuhi standar SNI. Paving block yang dikombinasikan dengan serat TKKS pada penelitian ini baik digunakan untuk halaman rumah,tempat parkir ataupun jalan setapak di taman-taman kota

The purpose of this study was to determine the content of the Sarang Semut extractive in various parts of the plant and weight. Sarang Semut are use in the study is that weight from 0-0,9 Kg; 1-1,9 Kg; 2-2,9 Kg; 3,-3,9 Kg; 4-4,9 Kg; 5-5,9 Kg; 6-6,9 Kg; 7-7,9 Kg and taken of three parts of the plant are: base, middle and end of the plant. Analysis of data using Completely Randomized Design (CRD) 8 x 3 factorial with three replications. The result of research on cold water extraction reflects differences in average levels of extractives in each treatment. On the weight of 5-5,9 kg extractives levels average growth of 34,72% and that is the lowest extraction levels. Highest extractive content of 40,56% of the weight from 0-0,9 kg. Difference in differences in average levels of extrative produce by 5,84%. Average levels of extractives obtained by extraction of cold water which is at the base of the highest (38,83%) followed by the tip (37,74%) then the middle (35,52%). The result of research on hot water extraction showed that extraction levels are highest in the treatment of 7-7,9 kg (44%) and the smallest in treatment 4-4,9 kg (37,78%). Difference in difference of 6,62%. Hot water extraction to produce more levels of extraction from the cold water extraction. This relates to the nature of the extractive substances are more soluble at high temperatures. Extractive substances more easly dissolved and more soluble in hot water extraction than cold water extraction.Key Words : sarang semut (Myrmecodia sp), cold water extraction, hot water extraction, extractive

Imperata grassland can be found in South Kalimantan in great amount and is known as a nuisance weed plants. The research is conducted to find out reed’s chemical content and its properties to know the description of the nature of the fiber as raw material for pulp and paper. The result of the research shows the water content of Imperata grassland is 97.76%, extractive content is 8.09%, the lignin content is 31.29%; 59.62% of holocellulose, 40.22% of alphacellulose, and 18.40% of pentosan. The second phase of the study of Imperata grassland fiber anatomy have been completed with the results of the fiber diameter is equal to 20 μm; 8.75 μm of lumen diameter, cell wall thickness is 5.65 μm and fiber length is 2.19 mm mm. Value of the derivative dimension of the Imperata grassland fiber obtained as follows: runkel ratio is 1.29; 42.24 (%) of mulstep number, power loom is 109.37, the valueof flexibility is 0.44 and stiffness coefficient is 0.28
