Abstract

ABSTRAKKeberhasilan pertumbuhan anggur laut Caulerpa lentillifera yang dikultur bersama dengan udang windu ditentukan oleh posisi yang tepat untuk menerima nutrien secara maksimal. Penelitian ini bertujuan untuk mengevaluasi pertumbuhan anggur laut dan udang windu pada posisi tanam di dasar dan lepas dasar di dalam tambak tradisional masing-masing dengan 10 ulangan.. Hapa berukuran 1x1 m dan nampan 25x25 cm digunakan untuk memelihara kedua spesies ini. Selama masa pemeliharaan 35 hari, udang windu tidak diberi pakan buatan untuk mempertahankan tipikal tambak tradisional sebagai pemasok bahan pangan organik. Uji t independen mengindikasikan Laju Pertumbuhan Spesifik (LPS) anggur laut dan udang windu di dasar tambak (1,98 ± 0,32% dan 3,68±0,11% per hari) secara signifikan (p0.05) lebih tinggi dibandingkan lepas dasar (1,59±0,29% dan 3,50±0,31% per hari). Sementara itu, Efisiensi Reduksi Nutrien (ERN) dari Total Amonia Nitrogen (TAN) sebesar 38,53±4,48% yang mengindikasikan kemampuan C. lentillifera menyerap bahan anorganik. Studi menyimpulkan bahwa ko-kultur C. lentillifera dan udang windu memiliki efek sinergitas yang positif dan dapat dikembangkan di tambak tradisional. Untuk hasil yang lebih baik, disarankan C. lentillifera ditanam pada dasar tambak dan dikultur bersama dengan udang windu.Kata Kunci: anggur laut, ko-kultur, pertumbuhan, tambak tradisional, udang winduABSTRACTThe successful growth of sea grapes Caulerpa lentillifera co-cultured with tiger prawns is determined by the appropriate position to absorb maximum nutrients. This study aims to evaluate the growth of sea grapes and tiger shrimp in bottom and off-bottom planting position in traditional ponds with 10 replicates each.  Hapa 1x1 m and trays of 25x25 cm were used to rear these two species. During the 35-day rearing period, tiger shrimp were not artificially fed to maintain traditional ponds typical of organic food suppliers. The independent t-test indicated that the Specific Growth Rate (SGR) of sea grapes and tiger prawns at the bottom (1.98 ± 0.32% and 3.68 ± 0.11% day-1) were significantly (p0.05) higher than off the bottom (1.59±0.29% and 3.50±0.31% day-1). Meanwhile, the Nutrient Reduction Efficiency (ERN) of Total Ammonia Nitrogen (TAN) was 38.53 ± 4.48%, which indicated the ability of C. lentillifera to absorb inorganic materials. The study concluded that the co-culture of C. lentillifera and tiger shrimp had a positive synergistic effect and could be developed in traditional ponds. For better results, it is recommended to plant C. lentillifera at the bottom of the pond and co-culture with tiger shrimp.Keywords: co-culture, growth, tiger prawns, sea grapes, traditional pond

Abstract

ABSTRAK                                                           Telah dilakukan penelitian tentang peranan tanaman sebagai biofilter untuk menjaga kualitas air media. Penelitian ini dilakukan dengan beberapa rangkaian kerja yang dimulai pada bulan Juni - Agustus 2022 di UPT Laboratorium Terpadu Unkhair Kota Ternate. Penelitian ini dirancang dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri 3 perlakuan dan 3 ulangan selama 60 hari. Pengukuran dilakukan terhadap suhu, salinitas, DO dan pH, amoniak, nitrat dan nitrit pada setiap minggu. Estimasi dilakukan terhadap efektifitas biofilter tanaman terhadap ammonia (N) dan fosfor (P) pada setiap perlakuan, pertumbuhan mutlak dan sintasan (SR) udang galah dan dianalisis menggunakan ANOVA dengan uji F pada taraf kepercayaan 95%. Uji Fisher (LSD) dilakukan apabila perlakuan berpengaruh nyata terhadap peubah yang diukur (P0.05). Hasil analisis memperlihatkan bahwa ketiga perlakuan tanaman tidak berbeda dalam menyerap N dari limbah budidaya udang galah. Sedangkan untuk penyerapan P dari ketiga perlakuan, jenis pakcoy menyerap paling efektif (0.725 mgL-1) dibandingkan dengan tanaman seledrei (0.540mgL-1) dan selada (0.186 mgL-1) (P0,05). Selain itu pula, konsentrasi ammonia selama penelitian cenderung menurun. Pertumbuhan mutlak dan laju pertumbuhan spesifik pada ketiga perlakuan tidak signifikan berpengaruh (P0,05), sedangkan sintasannya signifikan berpengaruh (P0,05). Meskipun demikian, ketiga tanaman dapat digunakan sebagai biofilter dalam system akuaponik.Kata kunci: Biofilter, tanaman, akuaponik, limbah, udang galahABSTRACTIt has been studied how plants can act as biofilters to preserve the standard of media water. The UPT Unkhair Integrated Laboratory in Ternate City will be the site of this research, with work series beginning in June 2022 and lasting through August 2022. Three treatments and three replications were used in this study's completely randomized design (CRD), which lasted for 60 days. Temperature, salinity, DO and pH, ammonia, nitrate, and nitrite were all measured on a weekly basis. ANOVA with the F test and a 95% confidence level were used to estimate the efficiency of the plant biofilter against ammonia (N) and phosphorus (P) in each treatment, absolute growth, and survival (SR) of gigantic prawns. When the treatment had a significant impact on the measured variables (P0.05), Fisher's test (LSD) was applied. The analysis's findings demonstrated that N absorption from the giant prawn industry's waste did not differ between the three plant treatments. Regarding the three treatments' P absorption, pakchoi (0.725 mgL-1) absorbed P more efficiently than celery (0.540 mgL-1) and lettuce (0.186 mgL-1) (P0.05). Additionally, there was a tendency for the study's ammonia concentration to decline. Survival had a significant influence (P0.05), although the absolute growth and specific growth rates of the three treatments did not (P0.05). However, all three plants can be utilized in aquaponic systems as biofilters.Keyword: Biofilter, plants, aquaponics, waste, giant prawns

Abstract

ABSTRAK Salah satu faktor penentu keberhasilan produksi Budidaya perikanan adalah suksesnya proses transportasi pengiriman ikan dari produsen ikan ke konsumen. Salah satu resiko terbesar dalam sistem transportasi ikan adalah terjadinya stres dan kematian sehingga dapat mengakibatkan kerugian secara ekonomi. Sistem transportasi benih ikan harus mempertimbangkan lama perjalanan, biaya dan keselamatan sampai di tempat tujuan. Resiko kematian ikan dalam transportasi benih dapat merugikan pihak produsen benih dan konsumen. Dalam kajian ini, kami telah melakukan ujicoba dan pengembangan penggunaan bahan kimia racikan sendiri dengan nama ‘propack’ untuk menjaga menjaga kualitas air tetap ideal sehingga ikan saat ditransportasikan dalam kantong plastik tidak mengalami stres dan kematian. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan tablet ‘Propack’ terhadap tingkat kelulushidupan benih yang ditransportasikan dalam waktu tertentu. Objek penelitian ini menggunakan ikan nila (Oreochromis niloticus) ukuran 3-5 cm. Rancangan Percobaan menggunakan 4 perlakuan dan 5 ulangan sebagai berikut P0 adalah media air hanya oksigen tanpa penambahan tablet” Propack”, sedangkan pada P1 media air dengan oksigen ditambahkan propack sebanyak 40 ppm, P2 media air dengan oksigen ditambahkan propack sebanyak 60 ppm, P3 media air dengan oksigen ditambahkan propack sebanyak 80 ppm. Hasil menunjukkan bahwa kualitas ikan setelah 12 jam perjalanan menunjukkan berbeda nyata dengan antara perlakuan P0 dan P1, P2 dan P3. Pada saat 21 jam P0 mengalami banyak kematian benih sedangkan P1, P2 dan P3 masih bertahan dan sedikit mengalami kematian ikan. Setelah 30 jam dilakukan perhitungan tingkat hidup benih menghasilkan P0(2%), P1(80,6%), P2(81,8%), dan P3(77,6%). Tingkat hidup benih kemudian diuji Anova taraf signifikasi 5% dihasilkan bahwa perlakuan P1, P2 dan P3 berbeda nyata dengan perlakuan P0. Dapat disimpulkan bahwa perlakuan pemberian bahan tablet ‘propack’ dengan dosis 40-60 ppm memberikan hasil tertinggi untuk tingkat hidup benih ikan nila yaitu 80,6% dan 81,8%. Berdasarkan hasil temuan ini, aplikasi tablet ‘propack’ terhadap media air ikan saat transportasi menjadi temuan baru yang bermanfaat dalam proses transportasi ikan nila (Oreochromis niloticus). Kata kunci: Transportasi, nila, propack, oksigen ABSTRACTOne of the determining factors for the success of aquaculture production is the successful process of transporting fish from fish producers to consumers. One of the biggest risks in the fish transportation system is the occurrence of stress and death which can result in economic losses. The fish seed transportation system must consider the length of the trip, costs and safety to the destination. The risk of fish mortality in seed transportation can be detrimental to both seed producers and consumers. In this study, we have conducted trials and developed the use of a self-concocted chemical called 'Propack' to maintain ideal water quality so that when fish are transported in plastic bags, they do not experience stress and death. The purpose of this study was to determine the effect of the addition of 'Propack' tablets on the survival rate of seeds transported at a certain time.The object of this study used tilapia (Oreochromis niloticus) with a size of 3-5 cm. The experiment used 4 treatments and 5 repetitions as follows: P0 is water media with only supplemental oxygen "Propack" tablets, while P1 water media with oxygen is added 40 ppm Propack, P2 water media with oxygen added 60 ppm propack, P3 water media with oxygen 80 ppm of oxygen was added by propack. The results showed that the quality of fish after 12 hours of travel was significantly different from that between treatments P0 and P1, P2 and P3. At 21 hours P0 experienced a lot of death of the fry while P1, P2 and P3 still survived and experienced a few fish deaths. After 30 hours, the survival rate of the seeds was calculated to produce P0(2%), P1(80,6%), P2(81,8%), and P3(77,6%). The seed level was then tested for a 5% ANOVA level of significance which resulted that the P1, P2 and P3 treatments were significantly different from the P0 treatments. It can be said that the administration of the 'propack' tablet material at a dose of 40-60 ppm gave the highest results for the survival rate of tilapia fish, namely 80.6% and 81.8%, respectively. Based on these findings, the application of 'propack' tablets to fish water media during transportation is a new finding that is useful in the transportation process of tilapia (Oreochromis niloticus).Keywords: Transportation, tilapia, propack, oxygen

Beberapa penelitian terdahulu menyatakan ekstrak jeruju sebagai antimikroba karena kandungan senyawanya dapat memerangi penyakit, terutama pada bagian daun. Penelitian ini mengekstraksi daun jeruju dalam memisahkan kandungan senyawanya dengan bantuan pelarut yang akhirnya akan menghasilkan suatu ekstrak dan selanjutnya dianalisis karakteristiknya serta dihitung nilai persen rendemennya yang kemudian akan diuraikan secara deskriptif. Hasil penelitian menunjukkan serbuk daun jeruju yang digunakan sebagai ekstrak daun jeruju Acanthus ilicifolius Kabupaten Bangkalan memiliki karakteristik sampel yang berwarna hijau kecoklatan, bertekstur lebih kasar, memiliki rasa yang pahit dan berbau ciri khas, sedangkan serbuk daun jeruju yang digunakan sebagai ekstrak daun jeruju Acanthus ilicifolius Kabupaten Probolinggo berwarna hijau, bertekstur lebih halus, juga memiliki rasa pahit serta berbau ciri khas. Selain itu, ekstrak daun jeruju Kabupaten Bangkalan menunjukkan nilai persen rendemen yang lebih tinggi sebesar 1,2% dibandingkan dengan ekstrak daun jeruju Kabupaten Probolinggo yang memiliki nilai persen rendemen sebesar 0,6% sehingga menghasilkan kesimpulan bahwa ekstrak jeruju Acanthus ilicifoius Socah lebih baik kandungan senyawanya dari ekstrak jeruju Acanthus ilicifolius Probolinggo dan berpotensi dalam pengembangan obat alternatif. Kata kunci: Ekstraksi, Jeruju Acanthus ilicifolius, Ekstrak daun jeruju ABSTRACTThe Jeruju plant Acanthus ilicifolius in mangrove forests has a medicinal value that has not been fully explored. This study aims to obtain and compare Acanthus ilicifolius jeruju leaf extract from Bangkalan Regency and Probolinggo Regency which have the potential in developing alternative medicines. Several previous studies stated that orange extract is antimicrobial because the compounds it contains can fight disease, especially in the leaves. This study extracted Jeruju leaves by separating the compound content with the help of a solvent which would eventually produce an extract then analyzed its characteristics and calculated the percent yield value which would then be described descriptively. The results showed that the orange leaf powder used as an extract for Acanthus ilicifolius leaves for Bangkalan Regency had the characteristics of a brownish-green color, a rougher texture, a bitter taste, and a characteristic odor, while the powder for Jeruju leaves used as an extract for Acanthus ilicifolius leaves for the Regency of Probolinggo is green in color, has a finer texture, also has a bitter taste and a characteristic odor. In addition, the jeruju leaf extract of Bangkalan Regency showed a higher yield percent value of 1.2% compared to the orange leaf extract of Probolinggo Regency which had a yield percent value of 0.6%, leading to the conclusion that Acanthus ilicifoius Socah orange extract had better compound content. from the orange extract of Acanthus ilicifolius Probolinggo and has potential in the development of alternative medicine. Keywords: Extraction, Jeruju Acanthus ilicifolius, Jeruju leaf extract

Abstract

ABSTRAKSebaran terumbu karang di Indonesia sekitar 85% terancam rusak dan 50% lainnya mengalami ancaman kerusakan yang tinggi. Pada wilayah perairan Pulau Pramuka menunjukkan persentase tutupan karang hidup sebesar 20,65%-47,17% yang dikategorikan sedang hingga rusak. Apabila tidak segera ditangani, ini bisa berdampak buruk bagi ekosistem laut. Perlu adanya upaya restorasi agar dapat membantu pemulihan terumbu karang yang mengalami kerusakan. Oleh karena itu, penelitian ini bertujuan untuk membandingkan pertumbuhan karang pada ketiga modul transplantasi karang yang berbeda yaitu antara modul rocklife, PVC, dan spider agar lebih mengefektifkan dalam menentukan modul terbaik yang ingin digunakan pada kondisi perairan yang sama seperti Pulau Pramuka. Parameter perairan yang diukur meliputi suhu, kecerahan, pH, salinitas, oksigen terlarut, dan kecepatan arus. Penelitian dilakukan selama 4 bulan dengan menggunakan 60 sampel fragmen karang dari spesies Acropora sp. yang ditanam pada masing-masing modul transplantasi karang. Metode yang digunakan dalam penelitian ini adalah eksperimen dengan observasi selama 3 bulan dan analisis korelasi pearson serta metode statistik dengan regresi linear digunakan untuk memodelkan hubungan antara parameter oseanografi tertentu dengan pertumbuhan karang pada masing-masing modul. Hasil penelitian menunjukkan selama kurun waktu 3 bulan, parameter perairan yang diukur tidak menunjukkan perbedaan yang signifikan dalam mempengaruhi pertumbuhan karang. Namun, hasil penelitian menunjukkan adanya korelasi antara pH dan DO dengan pertumbuhan karang. Secara keseluruhan perbandingan dari ketiga modul transplantasi yang dilakukan di perairan Pulau Pramuka mendapatkan hasil, modul rocklife menjadi metode yang terbaik.Kata Kunci: Laju pertumbuhan, Modul transplantasi, Pulau Pramuka, Terumbu karang, Transplantasi KarangABSTRACTThe distribution of coral reefs in Indonesia is around 85% threatened with damage, with the other 50% experiencing a high threat of damage. In the waters of Pramuka Island, the percentage of live coral cover is 20.65%–47.17%, which is included in the moderate to damaged category. If not addressed immediately, this can have a negative impact on the marine ecosystem. Restoration efforts are needed to help recover damaged coral reefs. Therefore, this study aims to compare coral growth in three different coral transplant modules, namely between rocklife, PVC, and spider modules, to further streamline determining the best module to use in the same water conditions as Pramuka Island. The water parameters measured included temperature, brightness, pH, salinity, dissolved oxygen, and current speed. The research was conducted for 4 months using 60 samples of coral fragments from Acropora sp. species planted in each coral transplant module. The method used in this study was experimental, with observations for 3 months, and Pearson correlation analysis and statistical methods with linear regression were used to model the relationship between certain oceanographic parameters and coral growth in each module. The results showed that over a 3-month period, the measured water parameters did not show significant differences in influencing coral growth. However, the results showed a correlation between pH and DO  and  coral  growth.  Overall,  the  comparison  of  the  three transplantation modules conducted in the waters of Pramuka Island resulted in the rocklife module being the best method.Keywords: Coral reefs, Coral transplantation, Growth rate, Pramuka island, Transplant modules
