Piles of garbage found in Final Disposal Sites (FDS) can cause water pollution. Water pollution that occurs is caused by the presence of leachate. Water pollution that occurs due to the presence of leachate, it is suspected that there are excessive levels of chloride in the well water of residents around the TPA Tapanrejo Village, Sumbersewu Village, and Kumendung Village. In this village it is interesting to study the chloride content in well water whether it is still suitable for use as drinking water or not, considering that groundwater in this area contains waste contamination from landfill leachate. In this study, well water samples were taken from each village and then analyzed for chloride levels in the laboratory using the argentometric titration method. The results showed that chloride levels in well water in the three villages located in the TPA area, Singojuruh District, Banyuwangi Regency showed results below the threshold value set by the Indonesian Minister of Health. This shows that groundwater is not polluted by landfill leachate so it is suitable for drinking, bathing, washing and cooking water..

Several countries have applied desalination technology to deal with the clean water crisis. One type of desalination technology that is commonly used is Multi-Effect Distillation (MED). This option is the right type to convert seawater into drinking water. The cost of producing water and the need for low temperatures are factors that can provide opportunities for the use of renewable energy as a source of heat. However, in the past, MED has failed to compete with MSF - Multi Effect Flash. The downside is the cost of capital (CapEx - Capital Expenditure). This price creates an opportunity for a review of these deficiencies. The correlation between capital costs and plant capacity is one of the common methods for calculating MED plant capital costs. As a result, for a generating capacity of 10,000 - 16,000 m/day, the specific charge is never below $2400 per m³/day. In addition, the capital cost of the MED plant increases as the number of effects on the surface area of heat transfer increases. Then, the longevity of the mill, the level of salinity of the feed water, and the location of the factory establishment can also be used as other correlations in estimating the capital cost of the MED plant.
一些国家已经应用海水淡化技术来应对清洁水危机。一种常用的海水淡化技术是多效蒸馏(MED)。这个选项是将海水转化为饮用水的正确类型。生产水的成本和对低温的需求是为使用可再生能源作为热源提供机会的因素。然而，在过去，MED未能与MSF - Multi - Effect Flash竞争。缺点是资本成本(CapEx -资本支出)。这个价格为审查这些缺陷创造了机会。资本成本与工厂产能之间的相关性是计算MED工厂资本成本的常用方法之一。因此，对于1万至1.6万立方米/天的发电能力，具体费用从不低于每立方米/天2400美元。此外，MED装置的资本成本随着传热表面积上的影响数量的增加而增加。然后，磨机的寿命、给水的盐度水平和工厂的位置也可以用作估计MED工厂资本成本的其他相关性。

Wonogiri multipurpose dam in addition to having the function as hydropower as well as a source of irrigation water, drinking water, aquaculture and flood control are managed by Perum Jasa Tirta I. This study aims to analyze the water quality and water quality status of the Wonogiri Reservoir. The research was carried out in the Wonogiri reservoir which is located in the area of the Wonogiri reservoir and the river that enters the Wonogiri reservoir. The research was conducted in February and September 2020 (2 semesters) by conducting 2 samples. Water quality data obtained were compared with quality standards based on Government Regulation No. 82 of 2001. The status of water quality was calculated and analyzed using the Pollution Index (IP) based on Decree of the State Minister for the Environment No. 115 of 2003. Parameters that exceed the quality standard in the Bengawan Solo River Basin, PLTA Wonogiri in semester 1 are BOD at observation points I, II, V, and VII. Other parameters that exceed the quality standard are oil and fat at observation points II, IV, V, VII, and VIII. The status of water quality in semester 1 at points I, II, V, VII, and VIII is included in the lightly polluted category, so that at the observation point it can no longer match the designation of class III water. Water management efforts need to be made at this point. The parameter that exceeds the quality standard in the Bengawan Solo River Basin, PLTA Wonogiri in semester 2 is the BOD at observation point VI. The status of water quality in semester 2 at all observation points is included in the category of meeting quality standards, so that the water management efforts in semester 1 at points I, II, V, VII, and VIII are included in the lightly polluted category have been successful. In semester 2, all water quality observation points can still be used according to the designation of Class III water, namely for the cultivation of freshwater fish, animal husbandry, water for irrigating crops and / or other uses similar to these uses.
沃诺里多用途水坝除具有水电功能外，还具有灌溉水源、饮用水源、水产养殖和防洪等功能。本研究旨在分析沃诺里水库的水质和水质状况。该研究是在位于沃诺里水库和进入沃诺里水库的河流地区的沃诺里水库进行的。本研究于2020年2月和9月(2个学期)进行，共进行了2个样本。获得的水质数据与基于2001年第82号政府法规的质量标准进行了比较。根据2003年国家环境部长第115号法令，使用污染指数(IP)计算和分析了水质状况。第一学期在Bengawan Solo River Basin, PLTA woogiri中超过质量标准的参数为观测点I, II, V和VII的BOD。其他超过质量标准的参数有观察点II、IV、V、VII和VIII的油和脂肪。第一学期1、2、5、7、8点水质状况为轻度污染，观测点已不能满足三级水的要求。在这一点上，需要作出水管理努力。第二学期班加万索罗河流域PLTA Wonogiri水质超标的参数为第六观测点的BOD。第二学期所有观测点的水质状况均为符合质量标准的类别，因此第一学期第1、2、5、7、8个观测点的水质管理工作均为轻度污染类别。在第二学期，所有水质观测点仍可按照第三类水的指定使用，即淡水鱼养殖、畜牧业、灌溉作物用水和/或与这些用途类似的其他用途。

Synthesis of biodiesel from pond CPO has been done. Pond CPO is oil fraction in the liquid waste of the CPO factory, which is expected to be one of the raw materials to replace fossil raw materials. The synthesis was carried out in 2 stages: esterification to convert free fatty acids into methyl esters and then transesterification to convert triglycerides into methyl esters. The catalyst used was based on Lampung Natural Zeolite (LNZ), modified with 0.5 M H 2 SO 4 (H-LNZ) and used as a catalyst in the esterification stage. The next catalyst was LNZ, modified with KOH (OH-LNZ) and tested its catalytic activity in the transesterification reaction. The concentration of KOH was varied to determine the effect of base concentration on the catalytic activity of OH-LNZ at the transesterification stage. To determine the characteristics of the synthesized catalyst, characterization was carried out using XRD and FTIR. XRD characterization results show that LNZ is a type of clinoptilolite mineral at 2θ in the 9.907 area; 22.389; 22.748; 28.041; and 30.027°. There was a peak shift at 2θ in the 28.041° area for LNZ to 27.802° at 0.5 M OH-LNZ and also a decrease in intensity. This shows an interaction between the zeolite and KOH, and then K 2 O is formed. The formation of K 2 O is indication that impregnated KOH on the surface of zeolite matrix has been modified through the calcination process. The FTIR results show that the higher the concentration of KOH, the vibration of the O-H functional group also increases, but the vibration of the T-O functional group decreases. Biodiesel with the highest yield was obtained on 2 M OH-LNZ catalyst, 20.25% with 38.59% octadecanoic methyl ester linoleic, and other small percentages of other methyl esters. The viscosity of biodiesel is 0.95 mm 2 /s at 40°C.
以池塘CPO为原料合成了生物柴油。池塘CPO是CPO厂废液中的油馏分，有望成为替代化石原料的原料之一。合成过程分为两个阶段:酯化反应将游离脂肪酸转化为甲酯，酯交换反应将甘油三酯转化为甲酯。催化剂以楠邦天然沸石(LNZ)为原料，经0.5 M h2so4 (H-LNZ)改性后，用作酯化反应的催化剂。下一个催化剂是用KOH修饰的LNZ (OH-LNZ)，并测试了其在酯交换反应中的催化活性。通过改变KOH浓度来测定碱浓度对OH-LNZ在酯交换阶段催化活性的影响。为了确定合成催化剂的性能，采用XRD和FTIR对其进行了表征。XRD表征结果表明，LNZ在9.907区域2θ处为斜沸石矿物;22.389;22.748;28.041;和30.027°。在0.5 M OH-LNZ下，LNZ在28.041°区域的2θ处峰移至27.802°，且强度减小。这说明沸石与KOH发生相互作用，形成k2o。k2o的形成表明沸石基体表面浸渍的KOH经过煅烧过程得到了改性。FTIR结果表明，KOH浓度越高，O-H官能团的振动也越大，而T-O官能团的振动越小。在2 M OH-LNZ催化剂上，以20.25%、38.59%十八烷甲酯亚油酸和少量其他甲酯为原料，得到了收率最高的生物柴油。在40℃时，生物柴油的粘度为0.95 mm2 /s。

The FTIR results show that the higher the concentration of KOH, the vibration of the O-H functional group also increases, but the vibration of the T-O functional group decreases. Biodiesel with the highest yield was obtained on 2 M OH-LNZ catalyst, 20.25% with 38.59% octadecanoic methyl ester linoleic, and other small percentages of other methyl esters. The viscosity of biodiesel is 0.95 mm 2 /s at 40°C.","PeriodicalId":133390,"journal":{"name":"Jurnal Inovasi Teknik Kimia","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126404837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sugarcane bagasse is an organic waste that is quite abundant with high levels of α-cellulose. However, bagasse has not been utilized optimally even though bagasse can be used as a raw material for making pulp. Pulp is the basic material in the manufacture of paper, where most of its production uses wood as basic materials. This study aims to identify sugarcane bagasse as an alternative raw material for pulping in terms of the effect of the type of bleacher and the length of cooking time. The type of bleach used is H 2 O 2 and NaClO and the cooking time is 30 minutes, 60 minutes and 90 minutes with the soda process. The results of the study showed that there was an effect of using a bleacher type H 2 O 2 with a cooking time of 90 minutes resulting in a higher pulp yield of 29.37%, compared to the NaClO bleacher at a cooking time of 90 minutes which only produced a pulp yield of 29.05%. The results of the FTIR test show typical absorption peaks such as the O-H phenolic functional group, C=O ketone absorption group, aliphatic –CH- and aromatic stretching groups. Identification of the lignin component produced by the pulp yield has an IR spectrum that corresponds to the IR spectrum of standard lignin components and Aldrich and Kraft commercial IR spectrum.
