Abstract

Water quality index (IKA) is one tool to quickly predict the environmental quality status of an ecosystem or region to obtaining an alternative of the future management. Toanalyze the status of these indices utilize only data of environmental parameters that have been established as a key parameter determining the IKA. From the analysis of the mining area of PT KPC IKA with key parameters TDS, DO, COD, nitrogen (N) and phosphorus. (P) derived from the water quality of agricultural ecosystems, industry / mines and residential showed an index value of less well with thecategory (54.6163) on the interval 40 ≤ IKA <60. The low index value is proportional to the low value of ecosystem quality index industry / mining IKA (I) with a value of 45.82with categories of less well on the interval 40 ≤ IKA <60. Consider, that the index value of ecosystem quality residential IKA (H) and agricultural ecosystem quality index IKA (P) with good and excellent categories, then the ecosystem of industry / mining is the focus that needs to be considered for improved management efforts.

Abstract

During the present time, the coastal area is lack of interested by the farmer as the cultivation site of agriculture plant. It is caused by the problem constraint of land physical character and the climate (particularly, micro climate), so that most confined the kinds of plant may be cultivated. The more narrowed of agriculture area, then optimalizing the use of coastal area for developing agriculture is necessary to conduct, although must throungh various means with an environment reengineering, as climate modification, conservation efforts of land moisture, supplying irrigation water, and etc.So that in the research will be implemented the research on the melon plant cultivation with various treatment.But, these condition of micro climate can be manipulated or reengineered with using simple technology in shape of closed shade, so that can be created an ideal condition for cultivation requirements. The result show that melon plant cultivated under the shade with sprinkler irrigation and drip irrigation gives the highest result that is 325 kg/70 m2 or 4,65 kg/m2, the melon planted under the shade + sprinkler irrigation + mulse the result 272 kg/70 m2 or 3,89 kg/m2, while the lowest result is that planted without using the shade with sprinkler irrigation and drip irrigation : 200 kg/m2 or 2,86 kg/m2.

Abstract

Peningkatan pemanfaatan air tanah dan sarana sanitasi setempat yang tidak dikelola di permukiman padat telah berdampak negatif terhadap sistem air tanah, dengan terjadi penurunan muka air tanah dan pencemaran air tanah. Penelitian ini bertujuan untuk memperoleh tingkat pemakaian air dan pengembangan pengelolaan air imbuhan di zona-zona pemanfaatan air tanah Cekungan Air Tanah (CAT) Bandung, khususnya di Kota Cimahi, Jawa Barat. Pengelolaan air imbuhan di permukiman perkotaan dapat dilakukan dengan pendekatan sanitasi, diantaranya melalui metoda resapan air tanah dari air hujan atau dari air olahan suatu instalasi pengolahan air limbah. Sehingga klasifikasi zona amanair tanah dapat berkelanjutan dan zona rawan atau kritis dapat dilakukan pencegahan dan penanganan di sumber imbuhan. Peresapan curah hujan buatan (artificial recharge) di zona-zona pemanfaatan air tanah dapat menghasilkan peningkatan sebesar 84,97 % dari jumlah total air yang teresapkan secaraalami. Sementara itu berkembangnya sanitasi on site dengan sistem cubluk, cenderung mencemari air tanah. Hal ini dapat dicegah dengan pengelolaan air limbah skala lingkungan, yang bertujuan menghasilkan air olahan yang dapat digunakan kembali atau untuk pengisian air tanah. Pengisian air tanah dari air olahan instalasi pengolahan air limbah skala lingkungan penting untuk mempertimbangkan ketersediaan lahan, kemudahan pengelolaan dan kesehatan masyarakat. Beberapa cara diantaranyadapat menerapkan beberapa tahap pengolahan dengan sistem biofilm, lahan basah buatan sistem aliran di bawah permukaan kemudian pengisian air tanah melalui filtrasi granular.Kata kunci : Air tanah, imbuhan, sanitasi , air hujan, air olahan

Abstract

Penelitian ini bertujuan untuk memperkenalkan biomassa mikroalga sebagai bahan baku biodieselalternatif yang ramah lingkungan. Perbandingan semua variabel biaya produksi antara mikroalgadan biodiesel kelapa sawit menggunakan proses produksi sistem analisis siklus analisis siklus hidupdiperpanjang (extended LCA) di evaluasi. Penggunaan sistem extended LCA dapat mencakupisemua variabel komoditas lingkungan sehingga potensi biomassa mikroalga sebagai materialyang terbarukan, rendah dalam penggunaan lahan dan berkelanjutan dapat dipromosikan. Nilai-nilai variabel komoditas lingkungan diperkirakan melalui pendekatan kesediaan membayar (WTP)menggunakan perangkat lunak yang di kembangkan oleh Strategi Prioritas Lingkungan (EPS).Hasil penelitian menunjukkan bahwa ada peningkatan biaya produksi biodiesel dari mikroalga danminyak sawit setelah dimasukkannya biaya variabel eksternalitas nya. Biaya produksi biodieseltertinggi berasal dari tahap segar produksi biomassa tandan buah kelapa sawit (49%-64 %) daritotal biaya. Analisis extended LCA menyimpulkan bahwa kenaikan mikroalga dan biaya produksiminyak biodiesel sawit adalah sekitar 2,6 % dan 17,7%. Biomassa untuk produksi biodiesel darimikroalga relatif lebih ramah lingkungan dibandingkan dari kelapa sawit karena berbagai kendalapada penggunaan mikroalga dapat ditangani. Selain itu, mikroalga memiliki kontribusi yang signifikandalam gas rumah kaca (GRK) mitigasi dengan mengganti bahan bakar fosil di masa depan melaluiperannya sebagai biodiesel.

Abstract

Environment is now an important global current issue and as a factor thatmust be considered in the implementation of Indonesian nationaldevelopment. Entering globalization era, the condition of environment willbe one of the parameters required for a country to be accepted in theworld free trade community. Instead, a country with bad environment cantherefore be charged for a penalty, such as a limited export quota. Forthat reason, starting now, Indonesia should improve their environmentalcondition by implementing a good environmental management in order toattain the standard of a good environment. If Indonesia cannot achievethis goal, Indonesia will be used by other countries as their big market,without the ability of Indonesia to export their products. If the standard hasbeen fulfilled, Indonesia can be part of the world free trade community inwhich this is a benefit for Indonesia itself. Without lowering the pace ofdevelopment growth, national development through holistic environmentalmanagement would be a proper program to implement. This program isconsidering the impact of development to the environment and thisprogram was commencing by the Indonesian government since 1970.However, it seems that the holistic environmental development has notbeen running smoothly, especially at the soft sides of development, suchas people awareness, environmental law, law enforcement, arbitrarycommittee, community development, environmental information includingpeople rights to get those information, the role of non-governmentorganization, etc.By considering the importance of environmentaldevelopment in a holistic way to fulfill the globalization requirements, thispaper would be focused on the factors that may inhibit the nationaldevelopment. Those are factors that affect sustainability of environmentalfunctions. Solution to the problems may also generally be described.

Abstract

Dengan adanya kemajuan bidang industri dan bertambahnya jumlah penduduk mengakibatkan semakin meningkatnya jumlah kebutuhan akan air, sehingga menjadikan air sebagai sumberdaya yang perlu dikelola dengan sistem pengelolaan yang tepat. Sepanjang sungai Citarum bagian hulu dan tengah dibangun 3 buah waduk yaitu Saguling, Cirata dan Ir.Juanda. Dalam hal pengelolaan air waduk Ir.Juanda yang terletak di daerah Jatiluhur, oleh pemerintah diserahkan kepada Perum Otorita Jatiluhur (POJ), terhitung mulai tanggal 23 Mei 1970. Dalam pengelolaan air waduk, sampai dengan tahun 1999, pihak POJ sudah 8 kali mengadakan kerjasama dengan UPT Hujan Buatan, BPPT untuk mengadakan kegiatan hujan buatan dengan tujuan menambah volume air waduk. Berdasarkan evaluasi yang dilakukan oleh POJ, dari kedelapan kali kegiatan hujan buatan, rata-rata telah dapat meningkatkan kemampuan fisik sebesar 80,1% dari target rencana operasional waduk.

Abstract

Nitrification is often not effective because the characters of nitrifying bacteria is always slow growing and temperature, pH, DO, amonia concentration, nitrite and C/N ratio as the limited factors. Batch experiment was operated for 6 hours, every half an hours ammonium, nitrite and nitrate were measured.The results showed that added C sourse (glucose) in medium from PDAM Bogorand Surabaya have a significant effects of ammonium degradation, nitrite and nitrate production. Degradation of ammonium in batch reactor from PDAM Bogor showed that both  naerobic and aerobic condition have a different fluctuation. Production of nitrite was stable from the middle of reaction to last of aerobic phase. In aerobic condition nitrate production is reduced to 49,21 % (+ glucose) and 60,87% (+ acetate) Batch reactor from PDAM Surabaya differ from PDAM Bogor particularly on degradation of ammonium. Added glucose as C source cause the concentration of ammonium was increased and acetate as C source showed stable with a slightly fluctuation. Nitrite and nitrate production relatively small in both C source.
