Abstract

Abstract   Liquid pesticide formulation in the form of emulsifier concentrate (EC) is more preferable because it does not form clogging and blocking in the tools and precipitating that harden. Based on fired capacity in the whole pesticide formulation industry, about 25 % produce emulsifier concentrate. In the emulsion formulation, the important point is unite insoluble matter become a homogeny and stable formulation for long period. The selection of emulsifier type is very important because it is influenced by quality and EC formulation stability. Result formula very good is 20 % propoxure; 5 % Malathion; 5 %; agrisol ; 20 % DBS; 45 % Xyline dan 5 % additive (%w/w), concentration affection test 0.025% v/v for thinner solvent in 20 strain aedes aegypti mosquitoes at Semarang killed on 2 hours = 4 mosquitoes, 4 hours = l0 mosquitoes, 6 hours = 16 mosquitoes and on 8 hours all mosquitoes had been died. From emulsion stability test, in oil phase and water phase was found terpentine as stable solvent in the emulsion form, with separated oil percentage at concentration 3mg/l about 42%. In water phase emulsion forms micro emulsion with white fog colors in whole concentration 1, 2 and 3 ppm   Keyword: Emulsifier Concentrate

Abstract

Abstract   Pesticide industries produce substance to kill pest and weeds, therefore product,side product, raw  material and its wastes are hazardous and poison. The main pollution from pesticides industries are air pollutant. According to property of the wastes, treatment wastes include combination of absorbtion, catalytic and condensation order to match with limiting value by government. After being treated, the component moritored i.e. CN was reduced from 10 mg/lt become 0.01 mg/lt   Keywords : cyanide, pesticide industry.

Abstract In Semarang limited landfill waste,new problems.If problems not handled and managed properly,an increase of waste that occur each year could shorten justify the air.In addition,the waste can the quality of natural resources,causing floods,and cause some diseased. Research to be conducted has several specific objectives,as follomposer EM-4.Minimizing the volume of waste in Semarang environment develop a network tool composter for organic fertilizer production of large-scale environmental and examine the addition of decomposers EM-4 the formation of humus to improve the productivity of organic fertilizer in environmentally friendly, operating condition optimization weathering process household waste using waste decomposer EM-4. Composter network of productivity environmentally friendly is expected to replace the function of inorganic fertilizers Research results:the best is on addition EM-4 8 ppm,with the following results:value ratio C/N 14,77;P2O5 1,24%;K2O 0,42%  SNI: ratio C/N 10-20 ;0,1% min P2O5 ;0,2%min K2O Keyword: EM-4 composer,liquid compost organic,organic waste

Abstract

Retno Hartati, Edy Supriyo, Muhammad Zainuri, in this paper explain that many salt industry is currently undergoing a inefficiencies process in the production system. Declining quality of salt from the salt ponds and lack of homogeneity in the iodine content of salt briquettes and much KIO3 wasted. So it is necessary to increase the iodine levels in salt. This activity aims to design, create and test a iodized salt machine with a capacity of 1-2 tons per hour and perform quality control on products. Community service activities have been successfully implemented by creating iodized salt machine. The process is done by means of iodized salt machine in the salt product becomes higher and meet ISO standards, in which prior to iodized salt machine the content of KIO3 is 0 ppm and become 50 ppm after using KIO3. Keywords : yodization, salt,screw, injection

Abstract

Potato crackers is one prime product of Wonosobo Regency, aside from carica and purwaceng.  One of potato crackers producers is UMKM Pakuwojo with brand of Pakuwojo. The demand of potato crackers is increasing form time to time. The problems faced by industry is peeling potato which done manually, so that need more time and labour. Therefore they need simple technology to increase their productivity, i.e. potato peeler machine. The machine is designed having capacity of  60 kg/hour, 150 rpm with power of 0,5 HP, equiped with water sprayer so the product has laready clean. The experiment to test the machine performance is used potato grade A and B. The result showed that in UMKM Paku Wojo, the machine performance is good having 150 rpm with capacity of 60 kg/hour. When it is operated for 50-60 minutes, the potato skin was  97,50% cleaned and losing weight of 1,5%. Keywords: potato peeler machine, performance, crackers

Abstract

Formula yang ada dipasar bebas hanya dapat membunuh nyamuk saja, maka dalam penelitian ini akan dilakukan  Produksi formulasi insektisida sebagai insektisida alternative pembunuh nyamuk dan jentik, dimana agrisol dan dodecyl benzen sulfonat merupakan emulsifier nonionic dan anionic sert bersifat hydrophilic. Penelitian ini bertujuan untuk menentukan konsentrasi emusifier yang tepat dalam proses formulasi insektisida, sehingga kestabilan emulsi antara minyak dengan air dalam waktu yang cukup lama Pada percobaan pembuatan emulsifier konsentrat kemudian dilakukan uji kestabilan emulsi antara minyak dan air serta uji effikasi Maka dapat diproduksi formula yang digunakan sebagai bahan dasar insektisida dalam membasmi nyamuk dan jentik nyamuk Aedes aigepty. Disamping itu juga dapat menjadi formula obat nyamuk (insektisida) alternatif yang mudah diaplikasikan oleh masyarakat. Hasil penelitian menunjukan bahwa emulsifier concentrat yang terbaik adalah pada percobaan dengan formula komposisi: 17,38% propoxure; Malathion 17,39% agrisol; 13,01%  DBS, 47,83 % Xyline dan 4,35% additive dalam % berat. Dengan total emulsifier yang digunakan 30,5 % w/w  equivalent dengan 30 EC  Dari uji kestabilan antara minyak dan air didapat pelarut yang terbaik adalah thiner, dengan membentuk micro emulsi pada lapisan air sampai 12 minggu lebih, kestabilan emulsi tercapai pada CMC 0,42 % v/v pada lapisan minyak. Dari uji effikasi dengan pengencer thiner sebanyak 10x setelah dianalisa profitabilitas sesuai LD 50, didapat dosis . 0,025 -0,25 % (v/v), baik untuk telur nyamuk maupun jentik Aedes aegypti dengan prosentasi kemation 45-90%  Effectiveness of Solvent Usage as a Solvent for Insecticide Formula in Eradicating Aedes Aegypti Mosquitoes to Prevent Dengue Hemorrhagic Fever Pesticide formulation which are available in market are only killed the mosquitos but not the larvae. Therefore Production formulation of insecticide as inscticide alternative to eridicate mosquitos and its larvae with agrisol and dodecyl benzen sulfonat as emulsifier nonionic and anionic hydrophilic. The reseach work was aimed to determine the best emulcifier concentrate in pesticide formulation  so that the emulsion of oil and water will be stable for a long time.  In reseach work the emulsifier concentrate was made, than emulsion stability test between oil and water as well as its effectivity were condected. This formulation could be used as active engridient for insecticide to kill Aedes aigepty mosquitos and its larvae and could be applied in the community.  The research showed that formulation consist of komposisi: 17,38% propoxure; Malathion 17,39% agrisol; 13,01%  DBS, 47,83 % Xyline dan 4,35% additive dalam % berat. Dengan total emulsifier yang digunakan 30,5 % w/w  equivalent 30% w/w.  Stability test of oil and water showed that the best solvent is thiner,  and formed micro emulsi on water film for more than 12 week.  Emulsion was stable by CMC 0,42 % v/v on oil film. From effication test and than analysis profitability revealed that LD 50, was . 0,025 -0,25 % (v/v), both for larvae and mosquitos presented dead 45-90%.
