(Muhammad Faisal Anggoro. 26040119130122. Analisis Kadar Amonia Terlarut Terhadap Bobot Udang di Tambak Udang Mangrove Jembatan Api-Api, Kulonprogo. Bambang Yulianto dan Suryono)
Budidaya udang vaname (Litopenaeus vanamei) menjadi andalan dalam budidaya karena menjadi komoditas ekspor unggulan di Indonesia dan mancanegara. Udang vaname memiliki tingkat kelangsungan hidup di atas 90 %, tingkat pertumbuhan cepat dan waktu pemeliharaan yang lebih pendek dibandingkan komoditas lainnya. Salah satu masalah yang dihadapi dalam budidaya yaitu adanya pencemaran amonia yang berasal dari sisa pakan dan feses udang yang dapat menjadi racun terhadap udang itu sendiri. Penelitian ini dilakukan bertujuan untuk mengetahui hubungan kadar ammonia terlarut terhadap bobot udang di tambak udang Mangrove Jembatan Api-Api, Kulonprogo. Materi yang digunakan dalam penelitian di tambak udang Mangrove Jembatan Api-Api, Kulonprogo adalah kadar amonia terlarut, bobot udang dan kualitas perairan lainnya. Kadar amonia terlarut, bobot udang dan kualitas perairan diperoleh melalu metode survei yang meliputi kegiatan observasi lapangan dan pengumpulan data primer dilakukan 2 kali sampling dimana sampling pertama selama 4 hari (DOC 165) dan sampling kedua selama 3 hari (DOC 53). Data kadar amonia diperoleh melalui uji spektofotometri (uji lab), sedangkan bobot udang diperoleh melalui timbangan digital.Hasil penelitian meliputi kadar amonia B4 0,564 mg/L, B6 0,1127 mg/L, BT2 0,0583 mg/L dan BT3 0,0699 mg/L, bobot rata-rata udang B4 34,66 gr, B6 36,86 gr, BT2 4,36 gr dan BT3 3,78 gr. Berdasarkan hasil penelitian kadar amonia terlarut pada lokasi penelitian rata-rata berada di bawah baku mutu tambak dan hubungan antara kadar amonia terhadap berat udang di tambak udang Mangrove Jembatan Api-Api, Kulonprogo yang didapat tidak menunjukkan pengaruh yang nyata terhadap bobot udang karena terkontrol.

ABSTRACT
(Muhammad Faisal Anggoro. 26040119130122. Analysis of Dissolved Ammonia Levels on the Weight of Shrimp in the Shrimp Ponds of Jembatan ApiApi Mangrove, Kulonprogo. Bambang Yulianto and Suryono)
Vaname shrimp (Litopenaeus vanamei) cultivation is a mainstay in cultivation because it is a leading export commodity in Indonesia and abroad. Vaname shrimp has a survival rate of above 90%, fast growth rate and shorter maintenance time compared to other commodities. One of the problems encountered in aquaculture is ammonia contamination from leftover feed and shrimp feces which can be toxic to the shrimp themselves. The aim of this study was to determine the relationship between dissolved ammonia levels and shrimp weight in the Jembatan Api-Api Mangrove shrimp ponds, Kulonprogo. The materials used in the research at the Api-Api Mangrove shrimp ponds, Kulonprogo were dissolved ammonia levels, shrimp weight and other water quality. Dissolved ammonia levels, shrimp weight and water quality were obtained through a survey method which included field observations and primary data collection. Sampling was carried out 2 times where the first sampling was for 4 days (DOC 165) and the second sampling was for 3 days (DOC 53). Ammonia content data was obtained through a spectrophotometric test (lab test), while the weight of the shrimp was obtained through a digital balance. The results of the study included ammonia levels of B4 0,564 mg/L, B6 0,1127 mg/L, BT2 0.0583 mg/L and BT3 0,0699 mg/L, the average weight of shrimp B4 34,66 gr, B6 36,86 gr, BT2 4,36 gr and BT3 3,78 gr. Based on the results of research on dissolved ammonia levels at study sites, the average was below the pond quality standard and the relationship between ammonia levels and shrimp weight in the Jembatan Api-Api Mangrove shrimp ponds, Kulonprogo, did not show a significant effect on shrimp weight because it was controlled.
