Abstract

Blood fever and Chikungunya cases in Indonesia are increasing annually. For preventing the mosquios, people use mosquito coil which is contain dangerous chemical compound. This research has successly created a natural mosquito coil with gemor bark and hazelnut fruit shell as the main material. Gemor bark is positive containing alcaloid,tanin, phenolk, flvonoid, triterpnoid and glycocydic compounds which are natural bioinsecticide. As formulation the comparison of gemor bark and hazelnut shell as follow :100% : 0 %  ; 80 % : 20 % ; 65 % : 35 % ; 50 % : 50 % ; 35 % : 65% and 20 % : 80% were used. Base one random variance analysis, the best formula was the using of gemor bark in 50%, 35% and  20% of concentration. The mosquitos killing force analysis was using the LT50 for 6 days with 5 diferent concentrations. The result showed that 50 %  of gemor bark was significantly influenced in the killing force. From the economic view, the producion of this coil was cheaper then the same product in the maket. Base on all the result, the research product is applicable in mass producion and safe for human health and the environment.Keywords: gemor bark , hazelnut fruit shell ,  mosquito coil, natural ,  ecofriendly

Abstract

One of the solutions to fulfill  the food sustainability is diversification of local food. One of the local food that potential to be used and processed is bamboo shoots. In South Kalimantan, the potential of bamboo as a producer of bamboo shoot plants with an estimated total area of 2158 hectares with a potential of 6 million stems. To increase the value and health of bamboo shoots can be made with fermentation. Fermentation is done by two methods, enzimatic fermentation and spontaneous fermentation. The results of the highest crude fiber obtained in spontaneous fermentation of bamboo shoots Haur 44.46% while the highest starch content present in fermented bamboo shoots Paring stater of 13.91%. Metal content, everything is still fulfill the quality standard. Flour bamboo shoots can be used as food supplements or raw materials of fiber flour.Keywords: bamboo shoots,  fermentation, fiber flour

Abstract

Rubber is one of important commodities in Central Kalimantan with more than 220.000 tons productions in 2013. However, the rubber immersion wastewater which has been discharged into the water body becomes problem. This research aims to know the effect of Al2(SO4)3, FeCl3 and PAC as coagulant in doses 2 g/L, 4 g/L and 8 g/L to reduce COD, BOD5, TSS, TDS and color concentration of the wastewater. Jar-Test was used with rapid mixing 200 rpm for 3 minute and slow mixing 50 rpm for 10 minute then settlled for 1 hour. The results showed that PAC with the dose of 4 g/L was better in reducing the COD, BOD5 and TSS than FeCl3 and Al2(SO4)3. After coagulation-flocculation, COD, BOD5 and TSS are 37,07 mg/L, 14,29 mg/L and 24,00 mg/L, respectively. On the other hand, TDS and color value showed higher concentration than standard with 514,00 mg/L and 106,00 PtCo, respectively.Keywords: Al2(SO4)3, coagulation-flocculation, FeCl3, PAC, rubber immersion wastewater ABSTRAKKaret merupakan salah satu komoditas penting di Provinsi Kalimantan Tengah dengan total produksi lebih dari 220.000 ton di tahun 2013. Permasalahan dalam produksi karet rakyat adalah limbah cair dari perendaman karet yang biasanya dibuang langsung ke badan air. Salah satu metode pengolahan limbah cair perendaman karet adalah dengan proses koagulasi-flokulasi. Penelitian ini dilakukan untuk mengetahui pengaruh jenis dan dosis koagulan Al2(SO4)3, FeCl3 dan PAC dengan dosis masing-masing sebesar 2 g/L, 4 g/L dan 8 g/L terhadap proses pengolahan limbah perendaman karet dengan metode koagulasi-flokulasi berdasarkan parameter COD, BOD5, TSS, TDS dan warna sebelum dan sesudah pengolahan. Penelitian ini dilakukan dengan menggunakan Jar-Test pada pengadukan cepat 200 rpm selama 3 menit, dilanjutkan pada pengadukan lambat 50 rpm selama 10 menit dan pengendapan selama 1 jam. Berdasarkan hasil penelitian diperoleh hasil bahwa PAC lebih baik dalam mereduksi konsentrasi COD, BOD5, TSS, TDS dan warna. Dosis yang disarankan berdasarkan penelitian ini sebesar 4 g/L. Konsentrasi COD, BOD5, TSS, TDS dan warna limbah perendaman karet sebelum proses koagulasi dan flokulasi belum memenuhi baku mutu Keputusan Menteri Negara Lingkungan Hidup No. KEP-51/MENLH/10/1995. Setelah diolah, didapatkan konsentrasi COD, BOD5 dan TSS berturut-turut sebesar 37,07 mg/L, 14,29 mg/L dan 24,00 mg/L yang telah memenuhi standar baku mutu limbah cair karet tetapi pada konsentrasi TDS 514,00 mg/L dan warna 106,00 PtCO masih belum memenuhi standar baku mutu limbah cair karet sehingga perlu pengolahan lebih lanjut sebelum dibuang.Kata kunci: Al2(SO4)3, FeCl3, koagulasi-flokulasi, limbah perendaman karet, PAC

Abstract

The use of ant nests (Myrmecodia pendens) native of Borneo as an antibacterial. The aim of this research is to make the crude drug  from the ant nest, simply extracting, condensing and test the ability of anti-bacterial properties of ant nests. This study covers the development of these extracts, proximate analysis, and test the antibacterial activity of plant-ant nest. Parameters measured were the growth of antibacterial activity against Salmonella sp., E. coli and Bacillus sp. showed by inhibition (clear zone). The results showed that plant-ant nests have antibacterial power. Ethanol extract of the ant nests provide a better inhibition compared with water extraction ant nests. Antibacterial activity of the ant nest extracts can be applied both in gram- positive and gram-negative bacteria. Key wood : ant nest, antibacterial,  inhibition capability
