Abstract

Barramundi (Lates calcarifer) is a high-value aquaculture species whose productivity strongly depends on the quality of broodstock management. In many government-operated hatcheries in Indonesia, feeding practices rely heavily on locally available trash fish without standardized supplementation, potentially affecting broodstock performance and water quality. This study aimed to document and evaluate feeding management practices for barramundi broodstock at the Teluk Buo Hatchery, West Sumatra, Indonesia. A descriptive case study was conducted over a one-month period through direct observation of feeding schedules, broodstock biometric data, and water quality monitoring. Broodstock were fed trash fish and squid at 3% biomass twice daily, supplemented with vitamins C, B-complex, and E on a scheduled basis. The broodstock ranged from 1.5–1.8 kg (males) and 5.7–6.5 kg (females), meeting recommended criteria for reproductive readiness. Water quality remained within optimal ranges (temperature 30.2–31.8 °C, salinity 30–33 ppt, pH 7–8, dissolved oxygen 5.5–6.3 mg/L), in compliance with national standards. These results indicate that structured feeding management contributes to broodstock health, gonadal maturation, and environmental stability. The findings provide a practical, replicable model for coastal hatcheries operating under resource-limited conditions and highlight the need for future studies addressing reproductive performance, economic feasibility, and sustainable feed alternatives.

Abstract

Aquaculture-based micro, small, and medium enterprises (MSMEs) often struggle with limited technology, weak management, and high production costs. This program aimed to strengthen the capacity of aquaculture MSMEs through the application of biofloc technology and semi-natural spawning techniques in catfish culture. The intervention was carried out with the “Maju Bersama” Community Business Group (KUBE) in Industritenayan, Pekanbaru, under the Community Development Program (Desa Binaan) of Universitas Riau. Methods included counseling, training, workshops, demonstrations, and mentoring on hatchery techniques, grow-out management, and entrepreneurship. Program evaluation was conducted using a participatory approach, measuring improvements in skills, seed production, and system sustainability. Results showed increased knowledge and skills of the target group in catfish breeding and farming. The establishment of a hatchery unit enabled independent seed production, reducing dependence on external suppliers and lowering costs. Biofloc systems improved feed efficiency, water quality, and survival rates. These outcomes demonstrate that integrating aquaculture technology with business capacity building can be an effective model of community empowerment. The program contributed to income generation, MSME independence, and supported Sustainable Development Goals (SDGs) related to decent work and economic growth.

Abstract

Limbah Rumah Sakit di Indonesia, khususnya limbah medis yang infeksius, belum dikelola dengan baik.Pemilahan yang baik akan didukung oleh perilaku petugas dalam penanganan sampah medis. Perilakupenanganan sampah yang tidak baik akan berakibat terhadap munculnya infeksi nosokomial. Ada beberapafaktor yang berhubungan dengan perilaku tenaga kesehatan dalam pemilahan sampah medis yaitu umur,pendidikan pekerjaan, pengetahuan, sikap dan masa kerja. Tujuan penelitian ini untuk mengetahuihubungan masa kerja dengan perilaku pemilahan limbah medis pada tenaga kesehatan di Rumah Sakit PMIKota Bogor. Jenis penelitian yang digunakan deskriptif analitik dengan pendekatan cross sectional.Pengambilan sampel dengan teknik accidental sampling sebanyak 35 perawat di Rumah Sakit PMI KotaBogor. Pengumpulan data ini menggunakan kuisioner. Analisa data yang digunakan yaitu analisa univariatdalam bentuk distribusi frekuensi pada karakteristik tiap variabel yang diteliti, dan analisa bivariatmenggunakan uji cramer v test. Hasil penelitian menunjukkan dari 35 responden didapatkan sebanyak 23responden (65,7%) dengan masa kerja yang lama (> 5 tahun) dan sebanyak 18 responden (51,4%) denganperilaku pemilahan limbah medis negatif. Hasil uji statistik didapatkan nilai p value 0,005 < 0,05 maka Haditerima dan Ho ditolak. Nilai Odds Ratio sebesar 0,655 dengan 95% CI pada 0,160 – 2,680 menunjukkannilai OR kurang dari 1 dan 95% CI minimal di bawah 1, dapat diartikan bahwa faktor masa kerja yang lama(> 5 tahun) cenderung 2,680 (1/0,655) kali mengakibatkan perilaku pemilahan sampah medis positif.Ada hubungan masa kerja dengan perilaku pemilahan limbah medis pada tenaga kesehatan di Rumah SakitPMI Kota Bogor. Disarankan untuk dijadikan bahan evaluasi penilaian pelaksanaan pemilahan sampahmedis melalui kegiatan pelatihan tentang pentingnya pemilahan limbah medis bagi tenaga kesehatan.

Abstract

Penelitian ini mengolah kotoran kucing menjadi pupuk organik cair. Pupuk organik cair (POC) memiliki kelebihan mudah diserap tanaman dan ramah lingkungan. Bahan utama kotoran kucing dengan kandungan C (12,18%) dan N (0,58%). Bahan pendukung sebagai upaya pemenuhan standar parameter POC yaitu kotoran kambing C (23,72%), N (2,08%), P (0,74%), K (0,33%) dan sisa makanan C (14,00%), N (0,39%). Penelitian ini menganalisis tentang pengaruh variasi bahan dan pengadukan terhadap suhu pada pupuk organik cair kotoran kucing. Proses dilakukan tanpa pengadukan, pengadukan 15 menit (4 jam/hari) dan pengadukan 30 menit (4 jam/hari). Tiga sampel dengan kandungan CNPK terbaik setiap variasi bahan diambil sebagai variasi umur simpan. Pengaruh variasi bahan dan pengadukan dianalisis terhadap suhu. Analisis pengaruh menggunakan MANOVA (Multivariate Analysis of Variance). Variasi bahan dan pengadukan berpengaruh terhadap suhu dengan nilai interpretasi (p < 0,05).

Abstract

Kelurahan Industri Tenayan termasuk ke dalam Kawasan Industri Tenayan (KIT) yang dimana terdapat kawasan industri dengan keberadaan perusahaan besar seperti PLTU dan PLTG, namun sebagian besar masyarakatnya masih bekerja di sektor informal dengan tingkat kesejahteraan menengah ke bawah. Sebagai langkah peningkatan ekonomi masyarakat, Pemerintah Kelurahan Industri Tenayan membentuk Kelompok Usaha Bersama (KUBE) Budidaya Lele Maju Bersama. Namun, kegiatan budidaya di KUBE tersebut masih dilakukan secara konvensional. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memperkuat ekonomi masyarakat melalui pengembangan budidaya ikan lele berbasis ilmu pengetahuan dan teknologi (IPTEK) di Kelurahan Industri Tenayan, Kota Pekanbaru. Mitra kegiatan adalah Kelompok Usaha Bersama (KUBE) Budidaya Lele Maju Bersama yang memiliki potensi besar namun masih menghadapi kendala dalam produksi. Metode pelaksanaan meliputi pelatihan dan pendampingan berkelanjutan dengan pendekatan partisipatif melalui kegiatan workshop pelatihan budidaya lele dengan sistem bioflok serta pelatihan manajemen usaha. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan mitra dalam teknik budidaya lele yang baik, serta pengelolaan usaha yang lebih terstruktur. Program ini diharapkan mampu mendorong kemandirian ekonomi masyarakat serta menciptakan usaha berkelanjutan yang ramah lingkungan.

Abstract

This study aimed to determine the effect of the Problem Based Learning (PBL) model assisted by Augmented Reality (AR) on improving the understanding of Integrated Science and Social Studies (IPAS) concepts among fifth-grade students at MI Ciomas. The background of this study was the low level of students' conceptual understanding caused by teacher-centered learning and the limited use of interactive learning media. This research employed a quantitative approach using a Pre-Experimental method with a One Group Pretest–Posttest Design. The research subjects consisted of 22 fifth-grade students selected using saturated sampling. Data were collected through essay tests that had been tested for validity and reliability. The data were analyzed using descriptive statistics, normality testing, and the Paired Sample t-test. The results showed that the average pretest score was 47.41, while the average posttest score increased to 84.50 after the implementation of the Problem Based Learning model assisted by Augmented Reality. The normality test indicated that both pretest and posttest data were normally distributed. Furthermore, the Paired Sample t-test yielded a significance value (Sig. 2-tailed) of 0.000, which was lower than 0.05, indicating that the null hypothesis was rejected and the alternative hypothesis was accepted. These findings demonstrate that the implementation of the Problem Based Learning model assisted by Augmented Reality has a significant positive effect on improving students' understanding of IPAS concepts. Therefore, the integration of Problem Based Learning and Augmented Reality can serve as an innovative and effective learning strategy to enhance conceptual understanding in elementary school science education.
