Abstract

Adsorption is an accumulation of contact between gas or liquid molecules with a solid surface and some molecules attached to the surface. This study uses adsorption as a pretreatment of membrane processing. The adsorption process is affected by several factors, including the flow rate used in the adsorption process. This study aimed to determine the effect of water flow rate on the adsorption process in removing Total organic Carbon (TOC) using Calgon and Haycarb Adsorbent. The characteristics of the wastewater used are effluent of wastewater treatment from alcohol production that remains contains Total Organic Carbon (TOC). Variation of the flow rate used is 39 mL/minute, 29 mL/minute, and 23 mL/minute. The effect of flow rate on adsorption pretreatment in removing Total Organic Carbon (TOC) on Calgon adsorbent showed that 23 mL/minute was the most effective in reducing TOC values. On the other hand, using Haycarb absorbent on 23 mL/min flow rates was less effective in removing TOC values. The Haycarb adsorbent effectiveness is shown by the morphology of the initial and final results of EDX, where the adsorbent pore of Haycarb is not filled with absorbate.

Abstract

Reservoirs are commonly used for aquaculture with floating net cage systems. The fish feed is not all eaten by the fish, so it is wasted to the bottom of the reservoir as uneaten feed. The organic content in the feed and the possibility of anaerobic conditions at the bottom of the reservoir waters can generate the decomposition process, which produces methane gas which is also a greenhouse gas. The floating net cages in the Sutami Reservoir, Indonesia, are about 173 ha in width, with the fish feed requirement of around 77.97 kg ha-1 day-1. Estimated uneaten feed and wasted to the bottom of the waters is about 2.3 g m-2 day-1, and methane gas emission from the feed waste is about 0.9 g m-2 day-1. This methane gas can contribute to methane gas in the atmosphere, so it is necessary to manage aquaculture, which has the potential to contribute methane gas as a greenhouse gas. Application of double nets on floating net cages can develop to attempt the reduction of feed waste in the fish farming system.

Abstract

A community service program was held in Surakarta city, in a boarding school named Kanzus Sholawat to solve the cooking oil waste problem. The used oil which locally is alluded to jelantah oil, blackish brown colored, contains exceptionally high levels of cholesterol, carcinogen, and it may cause harm for human wellbeing. Jelantah oil ordinarily will be directly thrown to the environment, hence may cause water and soil contamination. Agreeing to this, it is essential to teach individuals to do minimization and reuse to the utilized oil (jelantah). Besides, the individuals will be prepared to commercialize the items as a souvenir gift item. The jelantah oil will be processed into handwash cleanser products with a feasible, simple, and cheap procedure and utilizing effortlessly obtained material. To start, a 500 ml of used cooking oil is filtered and mixed with 160 grams of NaOH flakes soluted in 200 ml of water. Some drops of fragrance is added to make the soap perfumed. The purpose of this community service is to provide assistance to the Kanzus Sholawat Surakarta Foundation to take the economic value from the oil waste by commercializing the recycle product. The program will be carried out by training and education to handle the jelantah oil into handwash cleanser, and persistent assessment to make sure the Kanzus Sholawat Surakarta students and adjacent community get the optimal benefits. Pre-order sale system using e-commerce is also expected to be implemented by the students, to make this program sustainable.

Abstract

Landfill management in Indonesia is mostly operated by open dumping as well as the Klotok’s Landfill at Klotok Village, Kediri City. This landfill has three lands, and the third landfill is currently actively operating. The pollution is like the occurrence of leaks in leachate storage tanks which is near the Klotok river. That situation can make the leachate enter the river and affect the physicochemical conditions of the water which have an impact on decreasing the diversity and abundance of plankton. The diversity of plankton species in aquatic ecosystems is often used as an indicator to determine the primary productivity of waters and the condition of the aquatic ecosystem, so this research was carried out to determine the diversity of plankton species in the Klotok river, so the quality of the water can be known. This research was conducted in the Klotok River, Kediri City, East Java. Samples were taken upstream of the Klotok River, near the leachate treatment Plant, and downstream of the Klotok River. Samples were taken as much as 21 liters by pouring method. The samples are poured into plankton nets. The result shows that plankton diversity in the water body near Klotok landfill is between 0,49 to 0,67, which indicates that the diversity index according to Shannon-Wiener is 0,49 where the species diversity is low, the number of individual species is low, the ecosystem is unstable, and the waters are degraded.

Abstract

Pertumbuhan jumlah penduduk di Kota Tarakan akan meningkatkan jumlah timbulan sampah. Kota Tarakan terancam mengalami over capacity sampah dari lahan TPA Aki Babu sebagai satu-satunya TPA yang beroperasi di Kota Tarakan yang mana masih menerapkan sistem open dumping. Oleh karena itu, diperlukan relokasi atau pembangunan TPA baru. Sistem sanitary landfill adalah sistem operasi TPA yang dilakukan dengan cara memadatkan sampah secara berlapis, dimana periode operasi terpendeknya adalah selama satu hari. Keunggulan sistem sanitary landfill antara lain penanganan bersifat fleksibel walaupun terjadi fluktuasi timbulan sampah, dapat menampung berbagai jenis sampah, tidak menimbulkan permasalahan estetika, terdapat penanganan lindi dan gas, serta kebutuhan lahan yang relatif lebih kecil. Tujuan direncanakannya pembangunan TPA Juata Kerikil dengan sistem sanitary landfill di Kota Tarakan adalah untuk mengatasi ancaman over capacity dari TPA Aki Babu dan meminimalisir dampak buruk sampah terhadap lingkungan. Perencanaan pembangunan TPA Juata Kerikil menggunakan metode deskriptif analisis. TPA Juata Kerikil direncanakan dengan sistem sanitary landfill menggunakan metode trench. Lapisan dasar TPA menggunakan geomembran serta akan terdapat pipa pengumpul lindi dan pipa penangkap gas. Pada jalan-jalan TPA Juata Kerikil juga direncanakan saluran drainase. Selain itu, direncakanan pula instalasi pengolahan lindi untuk mengolah air lindi yang dihasilkan dari TPA Juata Kerikil.

Abstract

Fertilizer is a supporter of the country's food security, the government through State-Owned Enterprises (BUMN), one of which is PT Petrokimia Gresik, which is the most complete and largest fertilizer producer in Indonesia which produces several wastes, one of which is industrial wastewater. The existence of liquid waste is not expected in the environment because it has no economic value, therefore the need for waste treatment is very important. PT Petrokimia Gresik uses physical processing and chemical processing. PT Petrokimia Gresik has a wastewater treatment plant with a series of processes consisting of 2 effluent treatment units, equalizer, line injection, Urea Plant hydrolizer stripper, and sludge treatment. The parameters analyzed were Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Ammonia (NH3), Total Kjehdal Nitrogen (TKN), Fluoride, Degree of Acidity (pH), Oil and Fat. After conducting the research, the results of the analysis showed that the effluent pollutant load data was at the quality standards regulated in regulations. However, it was found that the results of TKN (Total Kjeldahl Nitrogen) or the amount of bound nitrogen in an organic substance varied.
