Pollution is one of the important issues faced by marine resources including zooxanthellae, which is known to be very sensitive to environmental changes. Some pollutants have been reported to have adverse effects on zooxanthellae, however, their sensitivity in regards to changes on cell size of these algae has not been widely explored. This study examined the effects of pollutants on the sensitivity of zooxanthellae through changes in size. Zooxanthellae were isolated from corals Porites lutea, Acropora aspera, and Montipora digitata collected from Panjang Island, Jepara, Indonesia. These algae were exposed to pollutants i.e. heavy metals (Cu, Cd, Pb) and nutrients (ammonium and phosphate) at concentrations of 5,10,15 ppb and 5,10,15 μM, respectively. Zooxanthellae size were measured five hours after pollutants exposure. The results showed that all treatments reduced the size of zooxanthellae. Algae isolated from P. lutea are the least affected by pollutants and the highest percentage cell size reduction was found in phosphate treatment. However, reduction on the size of algae were not statistically significant. These results indicate that in relation to reduction in the size, zooxanthellae are not sensitive to pollutants. Keywords: Zooxanthellae, pollutants, sensitivity, size reduction

Desa wisata Sanda memiliki potensi keladi/talas yang sangat banyak, hampir di setiap kebun penduduk tumbuh tanaman ini baik secara liar maupun telah dibudidayakan. Awalnya tanaman ini dianggap sebagai gulma yang mengganggu tanaman lain, sehingga sering dirabas untuk pakan ternak (babi) dengan terbentuknya kelompok wanita tani (kwt) keladi mulai dibudidayakan menjadi keripik dengan menggunakan alat yang sangatsederhana. Hasilnya ukuran atau ketebalan kripik tidak sama, rasanya belum bervariasi hanya rasa original saja. Untuk memberdayakan masyarakat dalam pengolahan keladi menjadi keripik diberikan pelatihan. Pelatihan yang baik bukan hanya perlu dirancang dengan baik, namun juga perlu dievaluasi efektivitasnya untuk memastikan tercapainya tujuan. Jadi tujuan dari kegiatan ini adalah untuk mengevaluasi pelatihan yang diberikan apakah disukai oleh peserta dan bisa meningkatkan pengetahuan dan kemampuan peserta. Untuk mencapai tujuan tersebut disebarkan angket kepada peserta sebanyak 20 orang, dari data yang dikumpulkan dianalisis dengan model kirpatrck dan menggunakan analisis statistik beda dua rata-rata berpasangan (paired sample t test) dari analisis tersebut diperoleh hasil bahwa peserta sangat tertarik terhadap program pelatihan sangat baik sekali dan pelatihan yang dilakukan dapat meningkatkan pengetahuan dan kemampuan peserta dalam membuat keripik keladi dengan rasa yanglebih bervariasi. Kata Kunci: evaluasi, pelatihan, keladi, kreatif Sanda tourism village has the potential for taro/taro which is very much, almost every garden in the population grows these plants both wild and cultivated. Initially this plant was considered as a weed that disturbs other plants, so it is often seized for animal feed (pigs) with the formation of farmer women (kwt) taro began to be cultivated into chips using very simple tools. The result is the size or thickness of chips not the same, the taste has not varied only original taste. To empower the community in processing taro into chips, they were given training. Good training not only needs to be well designed, but also needs to be evaluated for effectiveness to ensure the achievement of objectives. So the purpose of this activity is to evaluate the training provided whether it is liked by the participants and can improve the knowledge and abilities of the participants. To achieve this goal a questionnaire was distributed to as many as 20 participants, from the data collected were analyzed with the kirpatrck model and using a statistical analysis of the difference in the two paired averages (paired sample t test) from the analysis it was found that the participants were very interested in the training program very well once and the training carried out can increase the knowledge and ability of participants in making taro chips with a more varied taste. Keywords: evaluation, training, taro, creative

Pantai Karang merupakan pantai yang cukup padat dikunjungi wisatawan. Untuk menjaga kelestarian pantai ini penting untuk dilakukan monitoring, salah satunya yaitu dengan menjaga kondisi perairan ini agar tetap stabil. Di pantai ini selain menjadi tempat rekreasi juga terdapat lokasi pemberhentian boat yang diduga menjadi sumber pencemaran logam berat. Kandungan logam berat di suatu perairan dapat diketahui dari beberapa komponen diantaranya air, biota dan sedimen. Logam berat pada sedimen lebih tinggi dibandingkan dengan di air, hal ini dikarenakan logam berat dalam jangka waktu tertentu akan mengalami pengendapan. Logam berat di suatu perairan juga dipengaruhi oleh parameter kualitas air diantaranya pH dan salinitas. Semakin tinggi pH dan salinitas maka perairan tersebut akan bersifat basa sehingga hal tersebut dapat berpengaruh terhadap kelarutan logam berat pada sedimen. Hasil uji logam berat Pb pada sedimen di perairan Pantai Karang berkisar antara 1,360 mg/kg hingga 7,148 mg/kg. Hasil pengukuran salinitas pada perairan Pantai Karang berkisar antara 30,3-31,6 ppt, sedangkan hasil pengukuran pH menunjukkan pH di perairan ini berkisar antara 8,0-8,2.
