ABSTRACT
To overcome the disadvantages of open pond and cement tube as an outdoor algal cultured system, a simple inclined algal culture system was developed. the system composed of an 18.9 L polyethylene terephthalate (PET)bottle placed on a degree adjustable stand using an air pump to generate water mixing and circulation. The system was tested by culturing 45 mL Oscillatoria sp. in 13 L Blue-Green-11 (BG-11)medium supplemented with 3 g L-1 NaNO3 in plastic bottle, which was placed on different angles of inclination, viz. 45°, 60° and 90°. The system was operated outdoor under natural daylight and temperature. After 11 days, 11.5 L culture medium was poured out and 11.5 L fresh medium was refilled. Algal cell was precipitated to measure algal yield. Then, cell harvesting was done every 7 days for 6 batches. This system could culture algae continuously for 5 batches. The highest productivity was 32.23 gram wet (gw) ×m-2×d-1, which was recorded from a second and fifth round of 45° angular system and also from third round of 60° angular system. The result showed that this simple inclined algal culture system can be done continuously for one and a half month with high productivity by 45° inclination, which was proved as a good mixing and circulation. Showing advantages over open-pond, this system was moveable and could reduce possibility of contamination.

Penelitian ini mempelajari pengalaman perempuan adat pendatang dalam mengembangkan berbagai respon terhadap sistem budaya padi pada masyarakat adat Kasepuhan Anyar. Perjuangan perempuan adat pendatang ini dihadapkan dengan serangkaian kerumitan dalam persoalan adaptasi budaya, identitas baru, relasi gender, relasi sosial-budaya dan berbagai relasi lainnya di dalam komunitas pada berbagai skala. Ragam strategi dan penyesuaian diri dilakukan oleh perempuan adat pendatang dalam proses subjektivitas dan membangun subjek dalam berjuang meraih akses dan kontrol atas pengelolaan sistem budaya padi dikaitkan dengan posisi suaminya di dalam komunitas. Subjek dalam penelitian ini adalah perempuan adat pendatang yang memutuskan untuk tinggal dan menetap di Kasepuhan Alam akibat menikah dengan laki-laki asal Kasepuhan. Penelitian ini dilakukan pada masyarakat adat Kasepuhan Anyar (bukan nama sebenarnya) yang menjadi bagian dari Komunitas adat Kasepuhan Banten Kidul. Penelitian yang saya lakukan ini merupakan pendekatan kualitatif dengan perspektif feminis tipe fenomenologi. Metode pengumpulan data dilakukan melalui wawancara mendalam, observasi, observasi terlibat, dan studi data sekunder, hasil wawancara diolah melalui transkrip verbatim dan proses koding. Analisis hasil koding dilakukan dengan menggunakan teori ekologi politik feminis (feminist political ecology) dari Elmhirst (2015). Hasil penelitian menunjukkan ragam pengalaman perempuan adat pendatang dalam berjuang merespon sistem budaya padi yang tidak dapat dipisahkan dari kompleksitas persoalan relasi di dalamnya. Proses membangun subjektivitas yang dilakukan perempuan adat pendatang berkelindan dengan ragam dimensi (kelas sosial pasca menikah, usia, latar belakang pekerjaan sebelumnya), perempuan adat pendatang kelas elit membangun subjektivitas melalui pembuktian dan keberanian diri dengan terus melakukan budaya padi secara berulang dan berupaya meraih posisi sejajar dengan perempuan asli adat. Sementara itu perempuan adat pendatang kelas biasa hanya bisa pasrah menerima atas ketidakmampuannya dalam budaya padi. Konstruksi pengetahuan dan pemaknaan terkait sistem budaya padi dibangun melalui klaim relasi kuasa maskulin lewat filosofi sakuren. Perjuangan dalam meraih akses dan kontrol bersinggungan dengan ragam dimensi (kelas sosial pasca menikah, usia, posisi suami). ......This research studied the experience of migrant indigenous women in developing various responses to the rice culture system in the Kasepuhan Anyar indigenous people. The struggle of these migrant indigenous women is faced with a series of complexities in issues of cultural adaptation, new identities, gender relations, socio-cultural relations and various other relations within the community at various scales. Various strategies and self-adjustments were carried out by indigenous migrant women in the process of subjectivity and building subjects in struggling to gain access and control over the management of the rice culture system associated with their husband's position in the community. The subjects of this study were migrant indigenous women who decided to live and stay in Kasepuhan Anyar as a result of marrying a man from Kasepuhan. This research was conducted on the Kasepuhan Anyar indigenous people (not their real names) who are part of the Kasepuhan Banten Kidul indigenous community. This research used qualitative approach with a phenomenological type of feminist perspective. Methods of data collection were carried out through in-depth interviews, observation, participation observation, and secondary data studies, the results of the interviews were processed through verbatim transcripts and coding processes. Analysis of the coding results was carried out using feminist political ecology theory from Elmhirst (2015). The results of the research show that the various experiences of migrant indigenous women in struggling to respond to the rice culture system cannot be separated from the complexity of the relationship issues within it. The process of building subjectivity carried out by indigenous migrant women is intertwined with various dimensions (post-married social class, age, previous work background), elite class indigenous women build subjectivity through self-proof and courage by continuing to practice rice culture repeatedly and trying to achieve an equal position with indigenous women. Meanwhile, the ordinary class of migrant indigenous women can only accept their incompetence in rice culture. The construction of knowledge and meaning related to the rice cultural system is built through claims of masculine power relations through the philosophy of sakuren. The struggle to gain access and control intersects with various dimensions (post-marital social class, age, husband's position).
