Abstract

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

Abstract

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

Abstract

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

Abstract

Hutan Indonesia khususnya yang terletak di Kalimantan mengandung banyak kekayaan yang dapat dimanfaatkan. Salah satu manfaat hasil hutan dapat dijadikan sebagai bahan obat untuk alternatif menyembuhkan penyakit. Masyarakat suku Dayak Tomun adalah kelompok yang memanfaatkan tumbuhan sebagai bahan obat tradisional. Tujuan penelitian ini untuk mengidentifikasi jenis tanaman, bagian tanaman dan cara penggunaan tanaman yang digunakan oleh masyarakat sebagai obat tradisional. Metode kualitatif melalui wawancara mendalam digunakan untuk mendapatkan data primer. Responden yang dipilih mengggunakan teknik purposive sampling dengan kriteria masyarakat yang memiliki pemahaman dan pengetahuan tentang pengolahan tumbuhan obat tradisional. Hasil penelitian menunjukkan bahwa tanaman yang digunakan sebagai obat tradisional oleh masyarakat Dayak Tomun sebanyak 38 jenis dengan 26 famili. Bagian-bagian tanaman yang digunakan yaitu bagian daun sebesar 57,5%, bagian akar banyak digunakan juga untuk pengobatan tradisional sebesar 20%, umbi sebesar 7,5%, serta batang, bunga, dan getah hanya 5%. Cara penggunaannya yang dilakukan kebanyakan dengan cara diminum dari tanaman obat-obatan yang diolah yaitu sebesar 81,58%. Untuk cara penggunaan dioleskan terbilang banyak yaitu 10,53%, dan sisanya sebanyak 2,63% untuk cara penggunaan dikompres, dikunyah, serta diteteskan dari pembuatan obat tradisional.

Abstract

This study aims to analyze the quality of charcoal briquettes produced from a mixture of kolang-kaling processing waste and alaban wood charcoal processing waste. The parameters assessed include moisture content, density, ash content, volatile matter, fixed carbon, and calorific value. The research method involved sample preparation and characterization of biobriquettes using the Indonesian National Standard (SNI) 06-3730-1995, which includes tests for moisture content, density, ash content, volatile matter, fixed carbon, and calorific value. The carbonization process was conducted using a simple drum kiln, and the briquettes were molded using 10% tapioca starch as a binder. Five composition treatments were applied: (A) 100% kolang-kaling processing waste charcoal; (B) 75% kolang-kaling processing waste charcoal + 25% alaban wood charcoal; (C) 50% kolang-kaling processing waste charcoal + 50% alaban wood charcoal; (D) 25% kolang-kaling processing waste charcoal + 75% alaban wood charcoal; (E) 100% alaban wood charcoal. Each treatment was replicated three times. The briquettes were shaped using a manual press mold. The results showed that the briquettes had physical characteristics with a moisture content ranging from 5.490% to 11.641% and a density between 0.835–1.070 g/cm³. The chemical characteristics included an ash content of 1.497%–16.197%, volatile matter of 40.593%–47.177%, and a calorific value between 3,781.69–5,708.92 cal/g.
