Judul: Pola Penatagunaan hutan dan permasalahannya di propinsi dt I Jawa Barat
Abstrak: Penelitian tentang pola penatagunaan hutan dan permasalahannya di Propinsi DT I Jawa Barat dilakukan untuk menjawab sejumlah hipotesis yang diajukan, dengan tujuan untuk mengkaji kondisi pengelolaan dan permasalahan hutan (hutan negara) bidang tata guna hutan di daerah yang bersangkutan. Hasil penelitian diperoleh dengan penelusuran literatur, laporan, publikasi, dan interpretasi data atau peta, yang diperoleh dari berbagai sumber. Metode analisa pembahasan dilakukan dengan metode deskriftif. Berdasarkan penelitian, pembagian fungsi hutan ke dalam peruntukan hutan lindung, hutan produksi, hutan suaka alam dan hutan wisata, dasar-dasarnya sudah terdapat dalam kegiatan pengelolaan kawasan hutan di Jawa Barat sebelum dikeluarkannya dasar-dasar hukum penatagunaan hutan nasional yang mengatur peruntukan hutan sesuai fungsinya.

Judul: Pengaruh Perubahan Kebijakan Kehutanan terhadap Pengurusan Hutan Rakyat di Provinsi Jawa Barat dan CDK Wilayah IV Kabupaten Cianjur.
Abstrak: Hutan rakyat mempunyai peran penting terhadap petani hutan rakyat di Provinsi Jawa Barat. Perubahan Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintahan Daerah berpengaruh terhadap sektor kehutanan. Tujuan penelitian ini mengidentifikasi pengaruh perubahan peraturan perundangan tersebut terhadap pengurusan hutan rakyat. Pengumpulan data dan informasi dilaksanakan di KLHK, Dinas Kehutanan Provinsi Jawa Barat, CDK Wilayah IV Kabupaten Cianjur, serta Dinas Pertanian, Perkebunan, Pangan, dan Holtikultura Kabupaten Cianjur. Penelitian ini menggunakan analisis isi dan analisis perbandingan. Analisis isi terhadap perundangan yang berhubungan dengan hutan rakyat, tupoksi instansi terkait, dan tupoksi CDK Wilayah IV Kabupaten Cianjur dengan Dinas Pertanian, Perkebunan, Pangan, dan Holtikultura Kabupaten Cianjur. Hasil penelitian menunjukan bahwa tidak ada peraturan perundangan dan tupoksi yang secara jelas menyatakan tentang hutan rakyat. Berdasarkan analisis perbandingan jumlah kegiatan dan anggaran huta rakyat sangat sedikit dibandingkan dengan kegiatan dan anggaran untuk hutan Negara. Pemerintah lebih memperhatikan hutan Negara dibandin hutan rakyat.

Judul: Bioelectricity Production from Citrobacter freundii GBH253 and Chlorella pyrenoidosa on Microbial Fuel Cell Anode with Different Carbon Sources
Abstrak: Microbial Fuel Cell (MFC) development has significantly increased from various aspects to get higher and more stable electricity. Developing MFC on microorganism aspect is very important because it plays a crucial role in the MFC system. C. freundii GBH253 is one of the potential exoelectrogen bacterium that could be developed for the MFC system. Integrating C. freundii GBH253 and electricity-producing microalgae, such as C. pyrenoidosa, in the anode of MFC could get more stable and higher electricity. In this study, C. freundii GBH253 and C. pyrenoidosa were coupled to produce electricity from different substrates. C. freundii GBH253 and C. pyrenoidosa were tested on three different media types before being tested on MFC. They were also examined for the co-cultivation test to determine the symbiotic relationship between the two microorganisms. The MFC test was conducted using the Randomized Block Design Factorial and the Tukey test to see significant differences from each treatment. The parameters observed in this study were voltage, power density, Chemical Oxygen Demand (COD), Coulombic Efficiency (CE), pH, and volatile fatty acid (VFA). C. freundii GBH253 cannot grow on microalgae medium, while C. pyrenoidosa could grow on bacterial medium and a mixture of bacterium and microalgae media. The bacterium gained benefit from co-culture with microalgae. In the MFC test, electricity was generated in all treatments, which bacterium + microalgae with acetate treatment could generate power density up to 211,97 mW/m2 and the most stable compared to others. Production of electricity in bacterium-microalgae combination dominated by the bacterium; hence, microalgae still help bacterium by producing electricity and raised the COD value. The pH value of all treatments was higher than the initial pH. Acetate and phenol were VFA produced in all treatments, whereas butyric acid and propionic acid were found in some treatments. Pearson correlation showed that some VFA highly correlated with power density.
