Abstract

Absorption of heavy metals by plants is influenced by soil and plant biology. Heavy metals are absorbed into plant tissues through the root, then enter the food chain cycle. Metal will accumulate in body tissues and can have negative impacts for humans, animals, and plants when exceeding the limit of tolerance. Heavy metal accumulation in plant tissues can directly affect plant growth and production, can indirectly affect human health when consuming food contaminated heavy metals. The research objective was to determine the ability of biological fertilizers containing bacteria Azotobacter sp. and Pseudomonas sp., in absorbing heavy metals (Cu and Pb) contained in landfill waste compost, which is used to fertilize crops corn (baby corn). The research methodologyuses a split plot design arranged in Completely Randomized Design with 3 blocks as replicates. The first factor that serves as the main plot of the biological fertilizer, consisting of two cedars, namely: no biological fertilizers and biological fertilizers. The second factor that functions as a sub plot that is a combination of landfill waste compost with NPK fertilizer, consisting of four treatments, namely: Compost waste landfill: no fertilizer NPK = 1: 0; compost waste landfill: NPK = 2/3 : 1/3; compost waste landfill: fertilizer NPK = 1/3: 2/3Without landfill waste compost: NPK = 0: 1. The results showed that administration of biological fertilizers in combination with compost waste landfill is more dominant for increasing and improving soil physical chemistry, such as increasing soil pH, nutrients nitrogen, phosphorus and potassium and cation exchange capacity (KPK). Biological fertilizer containing bacteria Azotobacter sp. and Pseudomonas sp. may reduce the uptake of heavy metals Cu to below the threshold of 2.526 to 15.79 ppm, the maximum content of Cu ranges between 20-100 ppm. The mean content of Pb in tissues and cobs of corn is above the maximum limit of 29.80 to 42.69 ppm, which is still allowed Pb content between 0.1 to 10 ppm. Means baby corn crop is not safe for consumption.key words: compost from the landfill, heavy metals, biological fertilizer

Abstract

Teori lokal mulai dikembangkan setelah adanya kegagalan teori-teori yang didasarkan oleh filsafat rasionalisme. Paradigma Postmodernisme semakin memberi peluang pengembangan teori yang berbasis lokalitas dan komunitas. Kawasan Keraton Kasepuhan yang berdiri sejak abad ke 13 kaya akan nilai-nilai lokal. Didasarkan oleh pendekatan fenomenologi  menangkap suatu fenomena yang menunjukkan nilai lokalitas berupa gerak ruang. Gerak  adalah keluarnya sesuatu  dari titik kemungkinan  menuju titik yang dimungkinkan( Ammar, 1993). Gerak ruang yang terjadi di kawasan ini berupa gerak ruang substansi dan gerak ruang aksiden. Gerak ruang substansi yang ditunjukkan dalam fenomena gerak tradisi ke politik memiliki nilai lokal kesadaran integral dinamika spirit yang ditunjukkan oleh : keyakinan terhadap tanggung jawab sebagai pemegang amanahkeyakinan terhadap persatuan umat (keluarga)keyakinan untuk membuka diri pada yang lain Sedangkan gerak ruang aksiden yang ditunjukkan oleh kegiatan revitalisasi keraton memiliki nilai lokal “ kebersamaan “. Kata Kunci : Gerak   Ruang

Abstract

Di Indonesia, tanah-tanah marginal dengan kandungan pasir tinggi ( tanah vulkan berpasir kasar dan tanah berpasir digumuk-gumuk pantai), merupakan contoh dari banyak tanah bermasalah. Oleh karena itu upaya untuk mengatasi tanah bermasah tersebut perlu dilakukan. Budidaya pertanian pada tanah pasiran akan dijumpai banyak kendala yang berkaitan dengan sifat fisik, kimia dan hidrologi tanah serta iklim yang kurang kondusif bagi pertumbuhan tanaman, lebih khusus lagi tanah tersebut mempunyai sifat mudah meloloskan air, kandungan bahan organik rendah serta suhu tanah yang tinggi, sehingga kurang sesuai untuk pertumbuhan tanaman. Dengan menambah bahan pengkondisi tanah maka telah dapat merubah sifat fisik dan kimia tanah. Perubahan fisik tanah tersebut mengarah pada berat volume tanah yang meningkat, porositas tanah menurun,permeabilitas tanah menurun dan kadar lengas tanah meningkat. Keberadaan mikroba didalam tanah memegang peranan penting dalam transpormasi yang menyebabkan perubahan dalam sifat fisik dan kimia tanah.

Abstract

Usahatani pada lahan berpasir akan dijumpai banyak kendala yang berhubungan dengan kondisi fisik tanah, hidrologi tanah dan iklim, lebih khusus lagi kondisi iklim mikro yang kadang kurang kondusif untuk pertumbuhan tanaman. Oleh karena itu perlu adanya terobosan guna melakukan rekayasa lingkungan, agar supaya keadaan yang kurang menguntungan tersebut dapat dimanfaatkan secara optimal oleh petani, yaitu melalui masukan teknologi alternatif berupa penambahan bahan pengkondisi tanah (pupuk kompos, pupuk kandang, biomikro), pembuatan jaringan irigasi dan pembuatan pelindung/naungan yang pada hakekatnya berfungsi untuk mengurangi fluktuasi suhu harian pada tanah (intensitas matahari), penurunanpenguapan dan kehilangan air (evaporasi).

Abstract

The problem statements of this study include: 1) what are the types of criminal cases handled by the police; 2) how do the police handle the cases; and 3); how do the police’s insight of handling them alternatively. In the first year, the study aims to 1) establish the types of criminal cases handled by the police; 2) inventory the ways the police handle them; and (3) describe the police’s insight of a model for handling those alternatively. Hopefully, it can be beneficial for academicians and policy makers. For the academicians, it can be meaningful to contribute to criminal law development, particularly an alternative model for handling criminal cases. For the policy makers, it can be useful to develop a conceptual thinking to make a policy of handling criminal cases oriented to substantive justice.The study is a research of sociological law with qualitative approach. For this, the data included primary and secondary. The data employed a content analysis with legal and theoretical interpretations.Reserch product: In running its juridical responsibility, from January to May, 2011 the Polresta Surakarta has handled a variety of criminal cases. The types of these cases handled by the Polresta in 2011, particularly for five months, consisted of 33 cases. Out of the 2 felony cases were conventional at 25 criminal cases and unconventional (transnational) at 8 criminal cases. In handling the criminal cases, the Polresta Surakarta uses a fixed procedure as a reference to them, as stipulated in the Act of the Criminal Code, operating rule and guidance and technique of the Indonesian Police Administration. In facing the implication of the ADR to handle criminal cases, the Police have actually taken a better action. In the Telegram of the Criminal Investigation Bureau (STR), the Sub-Division of the STR of the Indonesian Police No ST/110/V/2011, dated on May 18, 2001 on the Implication Guidance of the ADR in the Rank of the STR of the Indonesian Police, the STR of the Indonesia Police will apply the ADR to handle criminal cases. Unfortunately, the policy is delayed with the Telegram of the STR of the Indonesian Police No ST/209/IX/2011, dated September 6, 2001 on Delaying the Implication of the ADR in the Rank of the STR of the Indonesian Police.

Abstract

Biaya produksi biodiesel menjadi salah satu hambatan program konversi bahan bakar minyak ke biodiesel negara-negara termasuk Indonesia dalam upaya mengantipasi terjadinya krisis energi. Salah satu penyebab biaya produksi yang tinggi adalah karena variabel biaya produksi yang diperbandingkan selama ini belum sepenuhnya mencerminkan keseluruhan potensi yang terkandung dalam biodiesel. Potensi biodiesel yang tergolong ke dalam komoditas lingkungan seperti sifat terbarukan, rendah dalam penggunaan lahan, dan ramah lingkungan perlu dimasukkan dalam perhitungan agar mendapatkan perbandingan perhitungan yang obyektif. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan komoditas lingkungan pada stuktur biaya produksi biodiesel dari minyak sawit dan minyak alga. Nilai komoditas lingkungan diperkirakan dengan metode metode benefit transfer dan untuk memperlihatkan nilai keuntungan digunakan pendekatan willing to pay (WTP). Nilai-nilai komoditas lingkungan diacu dari hasil perhitungan perangkat lunak Environmental Priority Strategy (EPS) versi 2000. Untuk kasus Indonesia, nilai komoditas lingkungan EPS diinferensi dengan elastisitas berdasarkan dari perbandingan nilai pendapatan per kapita negara Swedia dan Indonesia. Hasil penelitian menyatakan bahwa analisis life cycle costing (LCC) yang diaplikasikan dengan menambahkan variabel eksternalitas dapat memberikan informasi yang detil tentang komposisi biaya produksi biodiesel dan dapat digunakan sebagai metode untuk mendapatkan gambaran total biaya produksi yang paling kompetitif dari beberapa sumber.  Analisis juga menyimpulkan bahwa variabel eksternalitas turut mempengaruhi kenaikan total biaya produksi biodiesel hingga 14%. Hasil analisis profitabilitas menyatakan bahwa pasokan biomasa alga untuk produksi biodiesel lebih terjamin dan berkelanjutan dibandingkan biomasa sawit karena kendala teknis dan non teknis pada produksi biomasa alga lebih mudah diatasi selain itu juga keunggulan perannya dalam mitigasi GRK yang turut memperbesar peluang sebagai bahan utama biodiesel di masa depan.
