    Tulisan ini bertujuan untuk memberikan telaah kritis terhadap reposisi pelembagaan oposisi di parlemen berikut penguatan fungsi kontrol terhadap parlemen itu sendiri oleh masyarakat sipil. Dinamika sistem politik pasca orde baru mendesak terciptanya tatanan mekanisme checks and balances yang mampu mengakomodir peliknya persoalan tata kelola kebijakan publik dalam sistem presidensial dengan parlemen multi parpol ini. Tulisan ini dengan studi deskriptif analitis. Sumber data diperoleh dari referensi tentang partai politik dan pemilu serta relasi kuasa antar kekuatan politik. Tulisan ini mengambil setting celah parlemen yang membutuhkan kehadiran lembaga kontrol terhadap fungsi penyeimbang kekuasaan eksekutif sebagai konsekuensi dari pengejawantahan kewenangan yang cenderung dilematis. Penulis menyimpulkan bahwa jejaring masyarakat sipil dapat menjadi alternatif dominan untuk menjalankan peran pengawasan terhadap kinerja legislatif di parlemen. Ketika eksekutif secara konstitusional tak terlalu mampu mengimbangi fungsi pengawasan parlemen, maka reposisi organisasi masyarakat sipil yang dianggap sebagai representasi utuh dan ideal dari kepentingan masyarakat banyak, menjadi pilihan terbaik untuk meredam menguatnya demokrasi kolusif. Sinkronisasi regulasi, niat baik dari partai politik, peran control masyarakat civil, dan sinergisasi cara pandang terhadap konsekuensi sistem multipartai yang tumbuh menjadi dasar demokratisasi yang lebih maju

    KEDAWUNG (Parkia Timoriana) DAN KERABATNYA DI JAWA; PETIR (P. Intermedia) DAN PETAI (P. Speciosa) [Kedawung (Parkia Timoriana) and Its Related Species in Java; Petir (P. Intermedia) and Petai (P. Speciosa)]

    Kedawung is a member of the plant genus of Parkia (Mimosaceae). It has important value as traditional medicine and currently has been included in the Indonesian list of endangered medicinal plant species. There are two closely related species to Kedawung in Java: P. intermedia and P. speciosa. Parkia intermedia has long been assumed to be a hybrid between P. speciosa and P. timoriana. The species has leaflets linear-oblong and obtuse apex in mature foliage resemble P. speciosa, but has more numerous leaflets, linear-falcate, and acute apex in its juvenile leaflets similar to P. timoriana. Thus Hopkins (1992) included Petir as uncertain species. The aim of this study was to assess its current existing populations, to clarify the taxonomic status and to evaluate the similarity between kedawung and its related species. Exploration, morphology and leaf anatomical studies, as well as phenetic analysis have been conducted. The results indicated that morphology and leaf anatomical characters can be used to distinguish P. timoriana, P. intermedia and P. speciosa as different species, and P. intermedia was more closely related to P. speciosa than to P. timoriana

    Nilai CBR suatu bahan merupakan hal yang sangat diperhitungkan pada kontruksi baik jalan ataupun konstruksi lainnya. Penggunaan tanah yang distabilisasi untuk digunakan sebagai bahan konstruksi merupakan sebuah alternatif. Salah satu caranyaberupa meningkatkan kerapatan tanah dengan cara pemadatan dan mencampur dengan bahan stabilisasi tambahan untuk meningkatkan sifat-sifat tanah.Bahan yang digunakan pada penelitian ini adalah bahan stabilisasi merk “X” yang diproduksi Chemilink Technologies Group yang merupakan bahan polimer dalam bentuk serbuk. Bahan ini dapat merubah sifat fisis dan mekanis tanah seperti meningkatkan konsistensi tanah, meningkatkan kepadatan tanah, meningkatkan kekuatan tanah, dsb. Tanah yang digunakan adalah tanah yang tidak dapat digunakan untuk timbunan jalan menurut spesifikasi umum PU yang berasal dari Jalan Raya Caruban – Ngawi, Desa Purworejo, Kecamatan Pilang Kenceng, Kabupaten Madiun.Setelah dicampurkan bahan stabilisasi dengan variasi kadar 2.50%, 3.00%, 3.25%, 3.50%, 4.00% dan 4.50% terjadi Perubahan pada nilai batas atterberg yaitu penurunan PI seiring bertambahnya kadar bahan stabilisasi. Pada tanah asli PI sebesar 48,01% dan Perubahan terbesar pada kadar 4.5% sebesar 29.86%. Lalu pada specific gravity juga terjadi peningkatan, dari Gs tanah asli sebesar 2.62 menjadi 2.701 pada kadar bahan stabilisasi 4.5%. Kemudian pada uji pemadatan tidak ada korelasi pasti pada nilai OMC namun terjadi peningkatan pada nilai berat isi kering maksimum akibat reaksi bahan stabilisasi yang memecahkan gumpalan-gumpalan lempung sehingga tercapai kepadatan yang lebih. Pada uji CBR terjadi peningkatan nilai CBR akibat penambahan bahan stabilisasi, peningkatan jumlah tumbukan, dan penambahan lama waktu curing. Didapatkan korelasi antara jumlah tumbukan peningkatan CBR bahwa peningkatan nilai CBR pada tumbukan 56 dan 65 lebih baik dibanding 10 dan 30 tumbukan. Kemudian pada tumbukan 56 dan 65 terlihat korelasi yang jelas akibat lama waktu curing yaitu semakin lama waktu curing maka CBR yang didapat lebih tinggi. Dan nilai CBR yang melebihi nilai CBR agregat A terjadi pada kadar bahan stabilisasi 4.0% dan 4.5% pada waktu curing 7 hari baik 56 maupun 65 tumbukan yaitu untuk 4.0% sebesar 98.659% dan 97.920% lalu 4.5% sebesar 100.924% dan111.530%

    BACKGROUND: Vascular endothelial growth factor (VEGF) and brain-derived neurotropic factor (BDNF) present during early neuronal development and play important roles in the process of neurorepairing includes angiogenesis, neurogenesis and neuronal plasticity after ischemic stroke. In this study, we observed VEGF and BDNF levels of subjects with ischemic stroke in different onset time.METHODS: A cross sectional study was designed. Study subjects were 51 ischemic stroke subjects, aged 30-80 years old, recruited from Gatot Subroto Army Central Hospital, Jakarta, Indonesia. Ischemic stroke was diagnosed by neurologist, based on clinical examination and magnetic resonance imaging (MRI) result. Subjects were divided into 3 groups based on onset time of stroke: 30 days (Group C). VEGF and BDNF levels from serum were measured using lumine Magpix. The data was analyzed for comparison and correlation.RESULTS: VEGF and BDNF levels of group B and C were significantly different with p=0.034 and p=0.007, respectively. Group B had the highest VEGF levels, whereas Group C had the highest BDNF level. VEGF and BDNF levels in each group were not significantly correlated.CONCLUSION: Each stage of time after ischemic stroke has different recovery activities like angiogenesis, neurogenesis and plasticity. Angiogenesis process was optimum in 7-30 days after onset. in more than 30 days onset, Low VEGF with high BDNF have important role in a long period of time after the onset of stroke in the regeneration and repair, such as maintaining neuronal survival and plasticity

    This research aims to analyze and to describe the relation between the Constitutional Court of the Republic of Indonesia (CC) with the People Representatives' Council and the President of the Republic of Indonesia as legislators by looking on implementation of CC's decision through the legislation in the period 2004-2015. Using doctrinal research, it can be seen how the constitutional mandate in the CC's decision are implemented by the legislator through the legislation. The results are: (a) legal opinions of the CC's decision have a binding power; (b) a constitutional mandate in the legal opinion is intended as guidance for the legislators regarding what the 1945 Constitution requires; (c) directives to the legislator in the legal opinions should be implemented because it is the implementation of the principle of checks and balances according to the 1945 Constitution, (d) implementation of the CC's decisions through legislation does not have standard mechanism and does not become the priority of legislation, and (e) relation between the CC with the legislators can not be categorized in black and white in cooperative or confrontative, but shows ups and downs between cooperative and confrontative relations. Cooperative relations are realized when the constitutional mandate is formulated strongly so it is implemented by the legislator as the formula. Relationships tend to be cooperative in the implementation of the constitutional mandate of the decision, but not a priority of legislation. Meanwhile, the confrontative relations is seen from the constitutional mandate of the CC decisions which are not implemented
