As many as 20,000 plant species on earth can be used as a medicine and 11 percent or as much as more than 2,200 kinds of medicinal plants there are hiking Indonesia. One of the medicinal plants that have the potential to increase in value-added is <em>Temulawak</em>. In the area of Borneo total <em>Temulawak</em> in 2014 is 162.212 productions. One of the medicinal plants that have the potential to increase in value-added is <em>Temulawak</em> (Curcuma xanthorrhiza Roxb). <em>Temulawak</em> is one of the herbs that have the taste, aroma, and color typical of Rhizome Curcuma. Processing of Curcuma crops in Indonesia many carried out the purpose of this research is to know the influence of the number of concentration dilution Curcuma, and type of sugar (aren and sand), against the chemical properties and the acceptance of consumers, drink <em>temulawak</em> to enhance the consumer's receipt against the taste, the aroma of variant <em>Temulawak</em>. Manufacture of <em>Temulawak</em> has done with added sugar, Palm sugar, pandan leaves, and tamarind, with different concentrations, then analyzed the nutritional components, power thank consumers and consumer purchase interest. The results showed that the variation in the concentration of sugar concentration and <em>Temulawak</em> to sugar levels, variations in the concentration of sugar concentration and <em>Temulawak</em> to pH levels, and concentration of sugar concentration and <em>Temulawak</em> effect on total dissolved solids. Overall organoleptic results obtained 5% concentration of the sample extract and sugar concentration <em>Temulawak</em> 6% most preferred panelists.</p> Raudatul Dahliana Safitri Zulpahnor Zulpahnor Rabiatul Adawiyah ##submission.copyrightStatement## 2019-11-25 2019-11-25 5 2 40 46 10.20527/twj.v5i2.73 Production and Nutrient Quality of Rice Straw of Local Rice Varieties From South Kalimantan <p>A survey and laboratory study was conducted to estimate rice straw production of local rice varieties from South Kalimantan. Two local rice varieties (Siam Adil and Pandak) cultivated in a tidal swamp paddy field in Tanah Laut regency were harvested at the same time to estimate the dry matter production of rice straws and to obtain the rice straws samples. Rice straws samples were analysed to determine the percentage of botanical parts and nutrient contents, including the contents of dry matter, organic matter, crude protein, and crude fiber.&nbsp; Results showed Siam Adil rice straw had a lower percentage of leaf but had higher percentage of stem compare to Pandak. The botanical fraction of Pandak was similar to the improved rice variety (Ciherang). Siam Adil produced higher rice straw dry matter (7.95 tonnes/ha) compare to Pandak (5.83 tonnes/ha). There were no significant differences in the contents of dry matter, crude protein, and crude fibre of both local varieties. However, local rice straws had lower crude protein and higher crude fiber contents compared to the improved rice straw. In conclusion, local rice varieties potentially produced higher rice straw biomass but had lower nutrient quality. Thus, pretreatment is necessary to improve the utilization of local rice straw as a ruminant feed.</p> Ika Sumantri Sholih Nugroho Hadi ##submission.copyrightStatement## 2019-11-25 2019-11-25 5 2 47 50 10.20527/twj.v5i2.74 Mapping of Substrate Categories Changes in Exposure to Coral Reefs Using Alos Avnir-2 and Spot 7 Images in The South Area of Kotabaru District <p>The South of Pulau Laut is an area in the which is included in the Coral Triangle and Aquatic Conservation Areas. The purpose of this study was to map changes in the extent of coral reefs based on the class of substrate categories and objects on exposure to coral reefs in the southern waters of Sea Island within 6 years from 2011- 2017 using SPOT 7 satellite imagery in 2017 and AVNIR ALOS-2 in 2011. Using the method of Lyzenga Dept Index for basic invariant detection of waters. Based on the results of substrate-based classification using both satellite images overlaye, there has been a decline for the coral category as much as -19.21 ha, seagrass and algae as much as -3.57 ha. On the Contrary, the category of open substrate has Increased by 22.77 ha. Object-based classification results using the Object Based Image Analysis (OBIA) method have a reduction in area for the hard coral category (HC) of -1.66 ha, hard sand mixed with sand (HC S) of -15.99 ha, dead coral overgrown with algae and sand (DCA S) of -0.39 ha, algae and seagrass (FS) covering an area of ​​-1.65 ha, sand-mixed coral fragments (RS) of 4:45 ha. On the other hand, there was an increase of in the area.</p> Budimansyah Budimansyah Baharuddin Baharuddin Hamdani Hamdani ##submission.copyrightStatement## 2019-11-25 2019-11-25 5 2 51 62 10.20527/twj.v5i2.75 The Effect of Various Types of Mulch on the Growth and Yield of Dayak Onions (Eleutherine palmifolia (L.) Merr) <p>The research on the effect of various types of mulch on the growth and yield of <em>Dayak</em> onions (<em>Eleutherine palmifolia</em> (L.) Merr) has been carried out in the field at Al-Ikhwan complex, Banjarbaru City, South Kalimantan in March until July 2019. This research used a completely randomized design (CRD) single factor with 4 types of mulch treatment; m<sub>0</sub> = without mulch, m<sub>1</sub> = silver black plastic mulch, m<sub>2</sub> = rice straw mulch, m<sub>3</sub> = water hyacinth mulch, then repeated 3 times, thus 12 units of plot experiment. Each experimental unit contained 20 plants, with 6 sampling plant for observation. The parameters observed in this study were plant height, number of leaves, number of tillers, time of first flower appearance, number of bulb, and total fresh weight of bulb. The results showed that the treatment of various types of mulch could not affect the growth and yield of D<em>ayak</em> onions and there was not available the best type of mulch on the growth and yield of <em>Dayak</em> onions.</p> Rahmat Hidayat Hilda Susanti Dewi Erika Adriani ##submission.copyrightStatement## 2019-11-25 2019-11-25 5 2 63 69 10.20527/twj.v5i2.76
