Penggunaan sumber kalsium sintetik dengan ukuran partikel yang relatif besar di tambak diduga menyebabkan ketidaksempurnaan moulting pada budidaya udang vaname, Litopenaeus vannamei. Salah satu sumber yang berkelanjutan untuk memenuhi kebutuhan kalsium selama proses moulting adalah limbah cangkang dari biota perairan budidaya lainnya. Penelitian ini bertujuan untuk mengevaluasi penggunaan sumber kalsium dari cangkang moluska yang berbeda terhadap performa moulting dan pertumbuhan udang vaname. Penelitian dilaksanakan pada bulan Agustus-September 2021 bertempat di Laboratorium Hatchery dan Teknologi Budidaya Fakultas Pertanian, Universitas Malikussaleh. Penelitian menggunakan rancangan acak lengkap (RAL) non-faktorial dengan empat perlakuan tiga ulangan, yakni: A (penambahan tepung cangkang tiram 75 mg/L), B (penambahan tepung cangkang kepiting 75 mg/L), C (penambahan tepung cangkang remis 75 mg/L), dan D (kontrol), masing-masing tiga ulangan. Tahapan-tahapan dalam membuat tepung yaitu pencucian, penjemuran, penumbukan, pengayakan, dan pembuatan nannokalsium (furnace). Parameter yang diamati selama penelitian antara lain: jumlah individu moulting, kecepatan moulting, laju pertumbuhan harian, dan kandungan kalsium cangkang. Hasil penelitian menunjukkan bahwa perlakuan terbaik terdapat pada perlakuan A (penambahan tepung cangkang tiram 75 mg/L) menghasilkan jumlah individu moulting sebesar 77,50%; kecepatan moulting 2,00 hari; laju pertumbuhan harian 3,31%; dan tingkat sintasan 93,33%. Penelitian ini menghitung bahwa 1 ha tambak udang membutuhkan 6 kg tepung cangkang untuk mencukupi kebutuhan kalsium udang budidaya. Parameter kualitas air tambak yang diukur (suhu, pH, oksigen terlarut, salinitas, dan amonia) menunjukkan nilai optimal untuk pertumbuhan udang vaname. Penelitian ini menyimpulkan bahwa kalsium dari cangkang tiram paling baik dalam meningkatkan proses moulting udang vaname dan merekomendasikan penggunaannya sebagai alternatif sumber kalsium untuk menggantikan kalsium dari batu gamping.The use of synthetic calcium sources with relatively large particle sizes in brackishwater ponds is suspected of causing moulting imperfection in cultured Pacific white shrimp, Litopenaeus vannamei. One of the sustainable sources to supply calcium needs during the moulting process is the shell waste from other farmed aquatic biota. This study aimed to evaluate the use of calcium sources from different mollusk shells on the moulting and growth performance of Pacific white shrimp. The research was conducted between August-September 2021 at the Hatchery and Cultivation Technology Laboratory, Faculty of Agriculture, Malikussaleh University. The study used a non-factorial completely randomized design (CRD) with four treatments, namely: the addition of A (75 mg/L oyster shell flour), B (75 mg/L crab shell flour), C (75 mg mussel shell flour), and D (control, 0 mg/L of shell flour) in the rearing media with three replications. The shell flour was transformed into nano-calcium via different production stages. The parameters observed during the study included: number of moulting individuals, moulting rate, daily growth rate, and shell calcium content. The results showed that the best treatment was in treatment A (addition of oyster shell flour 75 mg/L) resulted in the number of moulting individuals of 77.50%; moulting rate of 2.00 days; daily growth rate of 3.31%; and a survival rate of 93.33%. This study calculated that 1 ha of shrimp pond required 6 kg of shell flour to sufficiently supply the calcium demand of cultured shrimp. The measured ponds’ water quality parameters (temperature, pH, dissolved oxygen, salinity, and ammonia) showed optimal values for the growth of Pacific white shrimp. This study concludes that calcium from oyster shell has the best in improving the moulting process of Pacific white shrimp and recommends its use as an alternative source of calcium to replace calcium from limestone.

Chlorella sp. is microalgae species used to treat wastewater and can grow and develop well inside contaminated environments by interweaving symbiosis with bacterial decomposers. This study purposed to evaluate the effectiveness of Chlorella sp. in the phytoremediation of different wastewater from North Aceh. This research used the experimental laboratory method with an experimental design Non-Factorial Completely Randomized Design. The treatment factor was different wastewater obtained from North Aceh consisting of A: domestic wastewater, B: tofu wastewater, and C: slaughterhouse wastewater repeated three times. The observed parameters were water quality parameters (temperature, pH, dissolved oxygen, biological oxygen demand, nitrate, and phosphate concentration, decrement of organic materials, and microalgae growth. The result showed that Chlorella sp. could remediate the wastewater by decreasing the organic materials in the wastewater. The temperature, pH, and dissolved oxygen in wastewater were optimal for Chlorella’s life. Implementation of Chlorella sp. gave a significant effect (p<0.05) on the efficiency of organic materials decrement in wastewater, namely BOD 64,6%-65%, nitrate 76,8%-91,2%, and phosphate 72,7%-94,6%. Furthermore, the suitable wastewater for Chlorella sp. growth with its highest peak value (p<0,05) was the slaughterhouse wastewater. The recommended wastewater was slaughterhouse remediated by Chlorella sp. to be used as cultivation media of fish.

Arthrospira platensis has emerged as a promising biodiesel feedstock due to its rapid growth and substantial biomass. In efforts to reduce production costs, researchers have explored alternative media derived from livestock waste to modify conventional mediums for Arthrospira platensis cultivation. The experimental design of this research employed a Completely Randomized Design, with treatments comprising inorganic fertilizer (A), chicken manure (B), cow manure (C), and goat manure (D). The livestock manures were macerated for seven days before being utilized as A. platensis medium. The results revealed significant (p < 0.05) impacts of different media on peak growth values and biomass production, reaching 2.03 ± 0.06 g/L and 1.76 ± 0.05 g/ L, respectively for chicken manure. The highest peak lipid content was observed in A. platensis cultured in goat manure medium. This study recommends goat manure as the preferred medium for mass cultivation of A. platensis. Mass cultivation in goat manure medium yielded 1.53 kg of dried biomass, with a lipid content of 1.91% and a biodiesel yield of 1.65%. The predominant fatty acid in this biodiesel was heneicosane, constituting 26.4% of the total area.

This research aims to investigate the influence of the project-based learning instructional model on students' science literacy skills and self-efficacy in rectilinear motion kinematics at SMA Negeri 1 Lhokseumawe. The research design employed is a quasi-experiment in the form of a Nonequivalent (Pretest And Posttest) Control Group Design. The study population consists of ten classes of eleventh-grade IPAS students at SMA Negeri 1 Lhokseumawe. The sampling technique used is purposive sampling, with XI IPAS 1 (36 students) selected as the experimental class using the PjBL learning model and XI IPAS 4 (36 students) as the control class using the direct instruction learning model. Data collection is conducted through a 10-item essay test and a non-test questionnaire on student self-efficacy comprising 20 statements. Data analysis utilizes the Manova test. This research indicates that the PjBL learning model impacts science literacy skills based on the Manova test results, which show 0.000 < 0.05, signifying a significant influence on the average science literacy skills. The PjBL learning model also influences self-efficacy according to the Manova test results, which demonstrate 0.004 < 0.05, indicating a significant impact on the average self-efficacy. Furthermore, the PjBL learning model affects science literacy skills and self-efficacy, as evidenced by the important results of the Manova test, 0.000 < 0.05. Therefore, it can be concluded that the null hypothesis is rejected, and the alternative hypothesis is accepted. Based on this, it can be inferred that the PjBL learning model influences the science literacy skills and self-efficacy of grade XI students at SMA Negeri 1 Lhokseumawe.Keywords: Project-Based Learning Model, Science Literacy Skills, Self-Efficacy
