Abstract

Chef carp (Carassius auratus) is a freshwater ornamental fish that is one of the ornamental fish that is widely cultivated because it has a diverse body shape and has a variety of colors. The problem often faced by carp suppliers in the process of distributing fish with a closed fish transportation system is low survival pass. The use of such anesthesia materials is quite effective in closed transport systems. One of the natural compounds that can be used as an anesthetic agent is rotenon. The roots of tubal plants contain rotenon, a powerful poison for fish and insects. The method used in this study is an experimental method, this study uses Complete Randomized Design (CRD) with 4 treatments and 3 repeats. The dose of tubal root extract used was P1 (control), P2 (0.10 ml / L), P3 (0.15 ml / L), P4 (0.20 ml / L). The density of fish per plastic bag amounts to 10 heads with a transportation time of 9 hours. The parameters observed were length of intoxication time, survival rate, length of time recovered consciously, oxygen consumption rate and water quality. Giving doses of tubal root extract with different doses had a significant effect (P<0.05). The highest survival rate value in P2 treatment with a dose of 0.10 ml and saving the rate of oxygen consumption with the right dose is in P4 with a dose of 0.20 ml / L ranging from 0.039 mg O2 / minute.

The chemical parameters obtained range from DO 5.56 – 6.76 mg/L, pH 7.71 – 7.89, alkalinity 162.37 – 184.94 mg/l, nitrate 3.72 – 4.22 mg/l, TAN 0.043 – 0.061 mg/l, phosphate 0.019 – 0.062 mg/l while the parameters that are not optimal are nitrite 1.39 – 1.52 mg/l. The biological parameters obtained by phytoplankton in ponds A, B and C were Chatoceros, Dinobryon, Lingulodinium, Nodularia, Oscillatoria, Planktothrix, Proboscia and cochlodinium species. Meanwhile, the zooplankton found in ponds A, B, C are Acartia, Nematodes and Nitocras pinipes.

Abstract

The urgency of this community service activity is the need for efforts to improve the economy of partners, one of which is by providing skills to partners to carry out freshwater lobster (LAT) cultivation activities that have a high selling price. LAT cultivation was chosen as one of the strategies to improve the economy of partners because in addition to the high selling price, LAT is also easy to cultivate and does not require a large area of ​​land, so the community service team is sure that partners are able to carry out this LAT cultivation activity. The purpose of this activity is to provide skills to partners about LAT cultivation using gutters arranged like apartments so that the results of this LAT production can increase partner income. This community service activity is carried out in two stages, namely a pre-survey which aims to find out partner problems and discuss solutions and the implementation stage, namely socialization of LAT cultivation and training in assembling solitary system maintenance media using gutters. Based on the community service activities carried out in Muka Sungai Kuruk village, Aceh Tamiang, the participants were very enthusiastic about all the programs implemented by the team. In addition, partners also hope that there will be a continuation of this activity, namely training on LAT seeding.

Abstract

Indonesia could potentially benefit significantly from economically important lobster species of the Panulirus genus, particularly the painted spiny lobster (P. versicolor) and the white-whiskered coral crayfish (P. femoristriga). Effective conservation decisions relating to these species require detailed knowledge of morphological variation and genetic relationships, especially in Palu Bay, Central Sulawesi, which is broadly considered pivotal for lobster conservation management. In this study, we conducted morphometric and genetic analyses to examine diversity and population structure of P. versicolor and P. femoristriga. From May to November 2021, a total of 72 specimens were collected in Kabonga Village, Donggala Regency, consisting of 53 P. versicolor and 19 P. femoristriga. Using the truss morphometric method, we divided the lobster body into four regions and measured 24 morphometric characters. Despite shared external traits, our truss morphometric analysis indicated that the two species represent distinct populations. Genetic analyses were performed on representative samples (n = 2) using mitochondrial COI sequences, confirming their identity as P. versicolor and P. femoristriga. Although haplotype analysis revealed genetic variability, the analysis of molecular variance (AMOVA) showed that the two populations shared genetic traits and had no significant genetic differences. Haplotype networks further indicated interconnections with more than one nucleotide substitution among haplotypes. Our findings demonstrate that although P. versicolor and P. femoristriga coexist in Palu Bay, they are morphologically distinct and require separate management and conservation strategies. These results provide baseline information for developing sustainable lobster fishery management in Central Sulawesi.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh integrasi pendekatan Social Scientific Issues (SSI) dengan model Project Based Learning (PjBL) terhadap hasil belajar siswa pada materi laju reaksi. Penelitian menggunakan metode quasi eksperimen dengan desain two group pretest–posttest. Populasi penelitian adalah siswa kelas XI IPA MAN 3 Medan, dengan sampel dua kelas yang dipilih secara purposive, yaitu kelas eksperimen dan kelas kontrol, masing-masing berjumlah 30 siswa. Instrumen yang digunakan berupa tes pilihan ganda sebanyak 20 soal yang telah divalidasi. Data dianalisis menggunakan uji normalitas, homogenitas, uji-t, dan uji N-gain. Hasil penelitian menunjukkan bahwa data berdistribusi normal dan homogen. Uji hipotesis menunjukkan nilai thitung (2,708) lebih besar daripada ttabel (1,671) pada taraf signifikansi 0,05, sehingga terdapat pengaruh signifikan penggunaan pendekatan SSI dengan model PjBL terhadap hasil belajar siswa. Selain itu, nilai N-gain kelas eksperimen (0,68) lebih tinggi dibandingkan kelas kontrol (0,64), yang keduanya berada pada kategori sedang. Temuan ini menunjukkan bahwa integrasi SSI dalam PjBL efektif dalam meningkatkan hasil belajar siswa serta mendorong keterlibatan aktif, berpikir kritis, dan kemampuan mengaitkan konsep kimia dengan isu sosial. Dengan demikian, pendekatan ini layak diterapkan sebagai alternatif pembelajaran kimia yang kontekstual dan bermakna.  The Effect of the Social Scientific Issue Approach with the Project Based Learning Model to Improve Student Learning Outcomes  This study aims to analyze the effect of integrating the Social Scientific Issues (SSI) approach with the Project-Based Learning (PjBL) model on students’ learning outcomes in reaction rate material. The study employed a quasi-experimental method with a two-group pretest–posttest design. The population consisted of eleventh-grade science students at MAN 3 Medan, with two classes selected through purposive sampling as the experimental and control groups, each comprising 30 students. The research instrument was a 20-item multiple-choice test that had been validated. Data were analyzed using normality, homogeneity, t-test, and N-gain tests. The results showed that the data were normally distributed and homogeneous. The hypothesis testing revealed that the t-value (2.708) was higher than the t-table value (1.671) at a significance level of 0.05, indicating a significant effect of the SSI approach integrated with the PjBL model on students’ learning outcomes. Additionally, the N-gain score of the experimental class (0.68) was higher than that of the control class (0.64), both categorized as moderate improvement. These findings indicate that integrating SSI into PjBL is effective in improving students’ learning outcomes, promoting active engagement, critical thinking, and the ability to relate chemical concepts to real-world social issues. Therefore, this approach is recommended as a contextual and meaningful alternative for chemistry learning.
