AbstrakIndeks saprobik merupakan indeks yang digunakan untuk mengetahui status pencemaran pada perairan dengan menggunakan keberadaan organisme seperti komposisi fitoplankton di perairan. Tujuan penelitian untuk mengetahui keanekaragaman fitoplankton dan kondisi kualitas perairan danau Situ Gunung, Sukabumi Jawa Barat berdasarkan nilai indeks saprobik. Sampel fitoplankton diambil dengan cara menyaring air danau sebanyak 20 liter dengan plankton net kemudian diawetkan dengan larutan Iodine 10%. Hasil penelitian menunjukkan terdapat 32 spesies fitoplankton ditemukan di Situ Gunung yang termasuk ke dalam 5 kelas yaitu, Chlorophyceae (66,58%), Cyanophyceae (25,82%), Bacillariophyceae (6,33%), Dinophyceae (1,01%) dan Cryptophyceae (0,25%). Jenis fitoplankon yang paling banyak ditemukan di Situ Gunung adalah Monoraphidium sp., Chroococcus sp., Gloeocapsa sp., dan Ankistrodesmus sp. Nilai indeks keanekaragaman (H’) di stasiun A = 1,02), stasiun B = 0,78, stasiun C = 0,39, stasiun D = 0,83 dan stasiun E = 0,6. Nilai indeks saprobik berkisar antara 1 s.d 1,67, yaitu dengan tingkat pencemaran ringan (β mesosaprobik) hingga sangat ringan (oligosaprobik) oleh bahan organik. Berdasarkan hasil tersebut, danau Situ Gunung termasuk ke dalam perairan yang belum tercemar.Abstract The saprobic index is an index applies to determine pollution level of water based on the presence of organisms such as phytoplankton. This study was conducted to determine the diversity of phytoplankton and water quality of Situ Gunung, Sukabumi, West Java based on saprobic index values. From this study, 32 species of phytoplankton were found that were members of five major classes: Chlorophyceae (66.58%), Cyanophyceae (25.82%), Bacillariophyceae (6.33%), Dinophyceae (1.01%) and Cryptophyceae (0.25%). The most abundant phytoplankton species found in Situ Gunung were Monoraphidium sp., Chroococcus sp., Gloeocapsa sp., and Ankistrodesmus sp. Diversity index (H') of station A, B, C, D, and E were 1.02, 0.78, 0.39, 0.83, and 0.6, respectively while saprobic index values ranged from 1 to 1.67, with the level of organic contamination ranging from light (β mesosaprobic) to very light (oligo saprobic). Based on these results, it is concluded that Situ Gunung has not been contaminated by pollutants.

Feed is one of the most important things in aquaculture. More than 50% cost productiondecided by feed. The increase of artificial feed price affected by raw material price rising could troubled the farmers and cultivator. Coconut husk as waste in traditional markets. This research purpose to know the utilization of coconut husk as alternative feed material. This research used experiment method composed of one control and three treatmenteach of it with three repetitive. The treatment composition with 5%, 10%, and 15% coconut husk flour. The observed parameter in this research is survival rate, weight absolute, specific growth rate, conversion feed, and water quality. The obtained result is the feed with 15% coconut husk flour formulation had the best result compared from control with survival rate 100 ± 0%, weight absolute 11,75 ± 1,46 gram, specific growth rate 2,89 ± 0,41% and feed conversion ratio 1,62 ± 0,16 without the alteration of water quality. Coconut husk flour can be used as alternative feed material with 15% in formulation.

AbstrakKapang endofit telah banyak ditemukan pada berbagai jaringan tanaman. Pemanfaatan kapang endofit dapat menjadi solusi untuk mengurangi eksploitasi tumbuhan yang berpotensi sebagai sumber senyawa bioaktif. Penelitian ini bertujuan untuk mengetahui keberadaan kapang endofit pada tangkai daun tanaman Kayu Jawa Lannea coromandelica dan potensinya sebagai agen antibakteri. Isolasi dilakukan dari tangkai tanaman Kayu Jawa dan isolat yang berhasil diperoleh dikarakterisasi secara makroskopis dan mikroskopis. Uji penapisan pada semua isolat dengan bakteri Staphylococcus aureus dan Pseudomonas aeruginosa untuk mendapatkan isolat yang berpotensi sebagai agen antibakteri. Ekstraksi isolat terpilih dilakukan dengan pelarut metanol (MeOH) dan pelarut etil asetat (EtOAc). Pengujian antibakteri menggunakan tiga bakteri uji, yaitu Staphylococcus aureus, Pseudomonas aeruginosa, dan Salmonella typhi. Hasil penelitian terdapat enam isolat yang berada di jaringan tangkai daun tanaman Kayu Jawa, yaitu PLC.1.A, PLC.1.B, PLC.2, PLC.3, PLC.4, dan PLC.5. Hasil uji penapisan menunjukkan isolat PLC.4 yang menjadi kandidat antibakteri pada penelitian ini. Fraksi MeOH memiliki aktivitas antibakteri lebih tinggi dibanding fraksi EtOAc pada semua bakteri uji dan kontrol positif (kloramfenikol) pada bakteri P. aeruginosa. Ekstrak MeOH isolat PLC.4 memiliki aktivitas antibakteri yang berpotensi sebagai sumber antibiotik baru.Abstract Endophytic fungi have been found in various plant tissues. The utilization of endophytic fungi can be a solution to reduce the exploitation of plants that are potential sources of bioactive compounds. This study aims to determine the presence of endophytic fungi on the petiole tissue of Kayu Jawa plants (Lannea coromandelica) and their potential as an antibacterial agent. Isolation and characterization of isolates was conducted macro- and microscopically. Screening test is carried out on the isolates against Staphylococcus aureus and Pseudomonas aeruginosa bacteria to obtain isolate that has the potential as an antibacterial agent. The extraction of selected isolates was carried out using methanol (MeOH) and ethyl acetate (EtOAc) solvents. Antibacterial examination used three test bacteria: Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhi. The results showed that six isolates were found in the petiole tissue of L. coromandelica, namely, PLC.1.A, PLC.1.B, PLC.2, PLC.3, PLC.4, and PLC.5. Screening result showed that PLC.4 isolate was a candidate for antibacterial agent in this study. The MeOH fraction had higher antibacterial activity than the EtOAc fraction in all tested bacteria and from positive control (chloramphenicol) on P. aeruginosa bacteria. In conclusion, the MeOH extract of PLC.4 isolate has antibacterial activity potential as a source of new antibiotics.
