Abstract

Proses penggandaan skala (scale up) umumnya dilakukan melalui penelitian skala laboratorium dan skala  pilot plant. Data yang dapat menjembatani adalah model kinetika reaksi,  yaitu konstanta kecepatan reaksi didasari oleh hukum Arrhenius, yang dapat dijadikan parameter dalam pengembangan proses yaitu penggandaan skala. Tujuan penelitian ini adalah mendapatkan model kinetika reaksi sulfonasi lignin isolat menjadi natrium lignosulfonat (NLS); mendapatkan volume/kapasitas reaktor optimum. Metode yang dilakukan dalam pengembangan proses (penggandaan skala) adalah melalui pendekatan sistematis empiris yaitu melibatkan model kinetika reaksi. Dengan membuat model matematika yang menghubungkan antara reaksi dan volume/kapasitas, serta simulasi pada berbagai kapasitas sehingga diperoleh kapasitas/volume reaktor optimum. Hasil penelitian diperoleh model kinetika reaksi berupa  konstanta laju reaksi yaitu:   (k) = 1,35703832 e-2558,89354/T mol-1 jam-1, yang dapat dijadikan paremeter dalam penggandaan skala (scale up) produksi natrium lignosulfonat (NLS), hasil perhitungan konsentrasi C A (mol/liter) menggunakan model kinetika reaksi disbanding dengan hasil yang diperoleh di laboratorium  menunjukkan validasi yang akurat. Model persamaan matematik yaitu hubungan antara biaya total NLS sebagai fungsi kapasitas produksi (P)  adalah  tc = 48.137 – 25,67 P + 0,001 P2 – 10-8 P3 + (2.593.011.921/P), dengan kapasitas/volume reaktor optimum adalah 23.425 kg NLS /tahun.

Abstract

ABSTRACT. Tofu liquid waste has a high potential to pollute water ecosystem, because so far it is disposed as is to sewerages around tofu factories. Nevertheless, tofu liquid waste is potentially convertible into biogas because it has BOD and COD exceeding 4000 mg/lt.The production of biogasfrom tofu liquid waste using an activator Effective Microorganism (EM4) is influenced by several underlying factors: volumes of waste,goat rumen and EM4. The objective of this study is to understand the feasibility of tofu liquid waste as a raw material of biogas, using additional materials of goat rumen and EM4 activator. The experiments were carried out in 5 batch reactors filled with 3000 ml waste and 300 ml rumen, and added with EM4activator varied for 0 ml, 25 ml, 50 ml, 75 ml and 100 ml. Based on our observations, it can be concluded that the addition of EM4in a batch process is positively correlated to the organicdecay of tofu liquid waste into biogas. The best result was observed in Reactor IV containing 75mlEM4where the biogas was produced after 72 hours. Keywords: tofu liquid waste, EM4 activator, cattle rumen, biogas

Abstract

Dalam pencapaian pembangunan Kota Depok, peranan transportasi darat memiliki posisi penting dan strategis, sehingga kebijakannya perlu dipadukan dalam satu kesatuan kebijakan manajemen transportasi darat dan dampaknya terhadap perekonomian masyarakat di Kota Depok. Berbagai kebijakan telah dikeluarkan, untuk meminimalisasi masalah transportasi darat tersebut, namun sebaik apa pun kebijakan tidak akan berhasil secara maksimal selama manajemen transportasi daratnya kurang dibenahi. Penelitian ini menggunakan metode deskriptif-kualitatif, karena berusaha menemukan fakta empiris dengan interpretasi yang tepat atas tindakan fenomena yang ada. Hasil penelitian: 1. Pemilihan transportasi darat yang sesuai dengan karakteristik Kota Depok, dan memperhatikan kebutuhan serta kepentingan segenap lapisan masyarakat yang berbedabeda, mampu menunjang efektivitas dan efisiensi penyediaan pelayanan angkutan umum kota. 2. Pembangunan jaringan transportasi darat yang memadai di Kota Depok telah mampu meningkatkan pertumbuhan sektor ekonomi masyarakat, meningkatnya nilai/ harga tanah, berkembangnya usaha skala kecil, menengah dan besar, terjadinya spesialisasi produk antar wilayah, terjadinya konsentrasi dan urbanisasi penduduk, terutama di daerah yang telah dibuka akses jalan dan angkutan. Sehingga terjadi peningkatan pendapatan Kota Depok dibarengi dengan distribusi barang secara merata antar penduduk, bidang usaha yang tersebar di beberapa wilayah. Di samping itu, terjadi peningkatan jumlah dan jenis barang jadi dan jasa yang mampu dihasilkan para konsumen, pemerintah dan kalangan industri. Kata kunci : transportasi darat, perekonomian masyarakat

Abstract

Udara adalah faktor penting dalam kehidupan, namun, di era modern, sejalan dengan perkembangan pembangunan fisik kota dan pusat industri, serta berkembangnya transportasi, telah menyebabkan kualitas udara mengalami perubahan. Dari yang mulanya segar, kini, kering dan kotor akibat dari terjadinya pencemaran udara karena kendaraan transportasi. Lewat penggunaan metode kepustakaan, maka, tampak dengan jelas ada beberapa hal yang harus mendapatkan perhatian yang serius, di antaranya; 1. Pemberian izin bagi angkutan umum kecil lebih dibatasi, sementara, kendaraan angkutan massal, diperbanyak. 2. Kontrol jumlah kendaraan pribadi. 3. Pembatasan usia kendaraan . 4. Pembangunan MRT, dan pembuatan Electronic Road Pricing. 5. Pengaturan lalu lintas, rambu-rambu, dan tindakan tegas terhadap pelanggaran berkendaraan. 6. Uji emisi harus dilakukan secara berkala pada kendaraan umum maupun pribadi. 7. Penanaman pohon berdaun lebar di pinggir jalan yang lalu lintasnya padat serta di sudut-sudut kota. Kata kunci: pencemaran udara, emisi gas buang, kehidupan, lingkungan

Abstract

Transportasi merupakan tulang punggung dalam mewujudkan kesejahteraan sosial di Jakarta. Oleh sebab itu, jika terdapat problem di dalam sistem transportasinya, maka, akan berdampak pada kelancaran lalu lintas dan akhirnya akan menghambat tercapainya kesejahteraan masyarakat. Penelitian ini menggunakan metode deskriptif-kualitatif. Penelitian ini merujuk pada teori yang dikemukakan oleh Anderson (dalam Tachjan, 2006: 23) dan Sarana, dkk (2009: 9). Hasil penelitian adalah sebagai berikut. Implementasi kebijakan sistem transportasi di Jakarta telah mampu meningkatkan kesejahteraan sosial sebagian warga masyarakat, artinya; sebagian masyarakat telah merasakan dan menikmati hasil pembangunan transportasi di Jakarta. Selanjutnya, sebagian yang lain belum secara maksimal merasakan dampak positif atas kebijakan tersebut. Bahkan yang dirasakan adalah dampak negatif; misalnya kemacetan yang hampir merata di seluruh wilayah Jakarta sehingga menimbulkan pencemaran udara yang cukup tinggi, aktivitas ekonomi masyarakat terhambat dan menimbulkan ekonomi biaya tinggi sehingga kesejahteraan sosial pun turut melemah. Hal ini diperkuat dengan angka kemiskinan yang terus meningkat di tahun 2014 mencapai 393,98 ribu orang dibanding tahun-tahun sebelumnya. Kata Kunci: kebijakan, transportasi, kesejahteraan sosial
