Kandungan kimia kayu acacia crassicarpa a. cunn. ex benth. pada berbagai umur

The objective of the research was to know the difference of chemical content for Acacia crassicarpa on different level of age. The TAPPI Standard was used to chemical content analysis such as, ashes, lignin, holocellulose, cellulose, hemicellulose, and extractiveand the ASTM standard for tannin analysis. The data analysis was used Random Complete Design (RCD) with pattern factorial 3 x 3, and 3 replication. Beside that, Tukey procedure used to test of the average. Generally the factor of age, the stem portion, and interaction to Acacia mangium or Acacia crassicarpa, are significantly difference for chemical woods content in ashes, lignin, holocellulose, cellulose, hemicellulose, extractive, and tannin. With difference test the average value, with two year age difference (6, 8, and 10-years old) and the stem portion (top, middle, and base of tree) show value difference. The average chemical content for Acacia crassicarpa are: 6-Year old : Ashes = 0,1933%, Lignin = 27,8467%, Holocellulose = 63,1489%, Cellulose = 31,6007%, Hemicellulose = 31,5461%, Tannin = 10,6553%, and extractive, are : Cold water = 4,0611%, Hot water = 5,4283%, Alkohol-Benzena = 5,0067%, and NaOH = 14,4683%. 8-Year old : Ashes = 0,2267%, Lignin = 29,3767%, Holocellulose = 65,2322%, Cellulose = 34,3741%, Hemicellulose = 30,8582%, Tannin =10,1758%, and ekstraktive, are : Cold water = 3,4350%, Hot water = 4,7739%, Alkohol-Benzena =4,5133%, and NaOH =14,5889%. 10-Year old :Ashes = 0,1789%, Lignin = 30,6011%, Holocellulose = 65,0822%, Cellulose =35,4896%, Hemicellulose = 29,5926%, Tannin = 7,8718%, and extraktif are : Cold water = 3,7800%, Hot water = 4,9400%, A llcohol-Benzena = 5,0917%, and NaOH = 14,6500%. The Acacia crassicarpa were already used as raw material for pulp and paper on 6 and 10 year, respectively, but the quality is not fain good because they need much chemical material for lignin bleaching, construction wood, plywood, laminated wood, particle board, etc. and the bark of these tree can produce tannin for : tanner, glue, etc. Keywords : chemical content, acacia crassicarp

Pemanfaatan Limbah Sagu Sebagai Bahan Pakan Ternak di Desa Pemakuan Laut, Sungai Tabuk, Kabupaten Banjar, Kalimantan Selatan

Sago plants can be used from leaves, fronds, and stems with the main product of sago starch from the stem. In the production process, the sago plants used are 7-8 years old. The productivity of sago palms in Pemakuan Laut village is around 200 kg starch/stem with a selling price of Rp. 3,500/kg in wet conditions and Rp. 7,500/kg of dry sago flour. Sago processing waste has not been utilized yet by the community even though the waste can still be used for other purposes such as animal feed, hardboard, fuel, plant growth media, and fertilizer. Sago waste is a problem in the Pemaku Laut village environment because the waste has accumulated while the location for disposing of it is limited. Therefore, in this community service activity training was carried out in making animal feed (poultry) using sago dregs. The method used is fermentation. From the activities carried out, it was known that all the participants had started to utilize sago dregs, but the preliminary process had not been carried out, the dregs were directly given to livestock. In this training, sago dregs processing is carried out using the fermentation process. From the training, it can be seen that the community already knows the process of processing the dregs before giving it livestock to increase its nutritional value

Sosialisasi Manfaat Sekat Kanal di Lahan Eks Pengembangan Lahan Gambut di Provinsi Kalimantan Tengah

Abstract:  The aims of this community service program is to socialize the canal blocking development program in Dadahup Sub District, Kapuas, Central Kalimantan. The program aims to restore the peat ecosystem to support food estate program.

CHEMICAL CONTENT AND ANATOMICAL CHARACTERISTICS OF SAGO (Metroxylon sagu Rottb.) FROND FROM SOUTH KALIMANTAN, INDONESIA

This research aims to evaluate the suitability of sago palm waste as a fiber raw material in terms of its chemical content and anatomical characteristics. The chemical content analysis of its extractive components, lignin, holocellulose, α-cellulose, and hemicellulose, was carried out using sago frond powder with a size of 40–60 mesh. Subsequently, functional group analysis was performed using Fourier Transform Infra-Red (FTIR), while anatomical characterization was carried out by calculating the fiber length and diameter, lumen diameter, fiber derivative values, and wall thickness using a microscope connected to a digital camera. Scanning Electron Microscope (SEM) pictures were taken in different magnifications. The results showed that sago frond contains 31.6% α-cellulose and 38% lignin. The α-cellulose content was within the standard range for non-timber forest products, but the lignin content had a relatively high value. Based on the derived value, namely class II, sago frond can be used as pulp and paper raw materials
