Abstract

Indonesia memiliki keanekaragaman hayati tanaman yang potensial yang dapat digunakan sebagai tanaman yang mempunyai kemampuan untuk mendegradasi dan mengakumulasi logam berat (hiperaccumulator). Tumbuhan hiperakumulator adalah tumbuhan yang mempunyai kemampuan untuk mengkonsentrasikan logam di dalam biomassanya dalam kadar yang luar biasa tinggi. Penyerapan dan akumulasi logam berat oleh tumbuhan dapat dibagi menjadi tiga proses yaitu penyerapan logam oleh akar, translokasi logam dari akar ke bagian tumbuhan lain, dan lokalisasi logam pada bagian sel tertentu untuk menjaga agar tidak menghambat metabolisme tumbuhan tersebut. Pemulihan lahan tercemar oleh logam berat secara biologi dengan menggunakan tanaman (fitoremediasi). Maka peneliti tertarik mengkaji tentang kajian akumulator tumbuhan air dalam menyerap beberapa logam berat dengan menggunakan metode teknik fotoremediasi. Hasil penelitian  tumbuhan air yang dapat dijadikan tumbuhan akumulator dalam memyerap logam berat yaitu tumbuhan Typha latifolia menyerap logam Cr, Hg, tumbuhan Eichornia crassipes menyerap logam Cr, Hg, tumbuhan Salvinia molesta , tumbuhan Hydrilla verticillata menyerap logam Hg, tumbuhan Ipomea aquatic menyerap logam Hg, tumbuhan hias lidah mertua memyerap logam Pb. Rata rata  tumbuhan air dalam menyerap logam berat  banyak terdapat pada  bagian akar. Tanaman air hyperaccumulator ini telah berevolusi melalui struktur dan fisiologinya, yaitu membentuk jaringan lakuna atau aerenkhima didalam akar dan batangnya untuk pertukaran materi dari bagian batang ke akar. Saat ini walaupun teknologi fitoremidiasi belum banyak diterapkan dalam pemulihan pencemaran tanah dan air, kedepan diharapkan  akan menjadi teknologi pembersih lingkungan yang potensial dengan keanekaragaman hayati tanaman di Indonesia yang dapat digunakan sebagai tanaman hiperakumulator, sehingga program pembangunan yang berkelanjutan (sustainable develeopment) dapat tercapai

Abstract

Anchovies are a group of pelagic fish that inhabit coastal waters and have a very wide distribution. In Indonesia, this species of fish are also preserved through the drying process. The humidity of the drying room must meet the humidity requirements required for drying of 55 - 60%. The natural drying process takes 8 hours of drying time per day for 3 days in areas with high sunshine intensity. Drying work must be accompanied by turning 2-3 times every day. The fish drying technology that has been completed is capable of drying fish for one hour with a capacity of 15 kilograms, and requires a supply of electricity of 3065.5 watts from the state electricity company. The high consumption of electric power required will affect the value of the production costs required so that it is necessary for this analysis to obtain an initial model of the location, type, number of turbines - solar panels, and batteries used to operate the fish dryer. The estimation result of the average daily electric power generated from wind speed is 389,53 watts hour (Wh) and solar energy is 5,79 watt hour. The total potential of electric power generated on period August - September 2020 is 2,31 kilo-watt hour (kWh).

Abstract

Government, through the Head of the Communication Bureau, Public Information Services and Cooperation, Ministry of Energy and Mineral Resources, conveyed a plan to build household gas networks in more than 50 districts and cities that aim to balance the mix of fossil energy use in society. The prepaid system is a payment system that allows users to enjoy services after making a payment. It aims to limit the service as needed, while the postpaid system allows its users to use the service indefinitely during the time span given by the service provider. Currently, the household gas network is equipped with postpaid meters, but it does not rule out the possibility of a prepaid system being applied if it is able to provide better convenience and comfort. Based on the research we conducted to determine public response of Cikarang society against the payment system, as much as 55% of the total sample studied preferred to use the postpaid system rather than the prepaid system on the household gas network. However, it is possible to use prepaid payment system for household gas networks (respondent's result is 35%) if the supporting facilities are continuously improved and developed for better service in the future.

Abstract

Livestock waste, such as bone, has always been ineffectively exploited. Bones contain organic compounds that can be further processed into usable products such as charcoal and activated charcoal. This research, therefore, aims to identify the optimum temperature conditions suitable for the manufacturing process of activated charcoal from goat bone waste using thermal activation. The study uses a two-stage process which is carbonization and thermal activation. Activation temperatures used in the process were at a temperature of 500 °C, 600 °C and 700 °C for three hours. The results of the characteristics of activated charcoal thermally produced in  this research met the Indonesian National Standard 06-3730-1995 about technical activated charcoal, and the  optimum conditions were at an activation temperature of 500 °C. These characteristics include the values of the water content at 1.210%, ash content at 2.034%, absorption of iodine 926 mg/g, volatile matter of 0.434% and fixed carbon of 96.616%.

Abstract

Considering Indonesia as an agricultural country, it certainly needs a support to have an adequate supply of fertilizer. Currently, the development of the fertilizer industry in Indonesia is quite rapid. Due to a large demand of fertilizers, the fertilizer industry is trying to provide good quality products to ensure customer’s satisfaction. In addition to improving product quality, fertilizer producers in Indonesia also strive to environmental management system aspects as an effort to implement ISO 14001:2015. The objective of this study is to analyze the comparison of environmental management system implementation among fertilizer producers in Indonesia, namely PT Pupuk Kaltim, PT Pupuk Kujang, and PT Petrokimia Gresik. The three fertilizer producers were chosen since they had already received ISO 14001: 2015 certification. The method used in this study is a qualitative method by analyzing and interpreting the data that has been obtained. The results show that the implementation strategies in environmental management carried out by the three fertilizer producers are not much different, almost all of them have the same strategy in terms of environmental management. However, PT Pupuk Kaltim has superiority in environmental management compared to its competitors, it is proven by the achievement of the PROPER gold at three consecutive years, while PT Pupuk Kujang and PT Petrokimia Gresik merely achieved the PROPER green category.
