Abstract

This research was conducted at the UPT. Balai Pelaksana Penyuluhan Ketahanan Pangan Pertanian dan Perikanan (BP2KP3) located at Jl. Keramat Indah, Medan Tenggara, Medan City, North Sumatra, from March to June 2024. The study aimed to assess the effects of applying liquid tofu waste organic fertilizer (POC) on the growth and yield of lettuce plants. The research used a Randomized Block Design (RBD) with four treatments and six replications, resulting in 24 experimental plants. The treatments applied were: P0 = 0% tofu liquid waste, B = 15% tofu liquid waste (150 ml/1 liter of water), C = 30% tofu liquid waste concentration (300 ml/1 liter of water), and D = 45% tofu liquid waste concentration (450 ml/1 liter of water). The study results indicated that applying doses of tofu liquid waste influenced plant height and leaf count parameters but had no effect on leaf area and net weight of the plants. From the study, it was concluded that the optimal impact of liquid tofu waste POC on the growth and yield of lettuce plants (Lactuca sativa L.) has yet to be achieved.

Abstract

This study aims to investigate the high-order thinking skills (HOTS), biological literacy, and the relationship between HOTS and biological literacy of Grade X students at SMA Negeri 1 Labuhan Deli regarding virus material. A sample of 36 students was randomly selected for this quantitative research, employing a descriptive quantitative method. Data collection techniques included interviews, documentation, and tests. Data analysis was conducted using statistical methods, particularly descriptive statistics. The findings revealed that students’ HOTS fell into the “good” category with scores ranging from 61 to 80, with the highest percentage of indicator occurrence (76.9%) for evaluating problems. Regarding biological literacy, students demonstrated a “very good” level of understanding in evaluating explanations (83.9%). In the aspect of conducting procedures, students achieved a “good” level (63.7%), while in explaining phenomena, they reached a “fairly good” level (46.4%). A positive correlation was found between HOTS and biological literacy in Grade X students’ understanding of viruses.

Abstract

This research aims to determine the effect of applying liquid organic fertilizer from Kepok banana stems on the growth and yield of Samhong mustard greens. The design used was a non-factual completely randomized design (CRD) with four treatments and six repetitions with doses of 0%, 10%, 20% and 30%. This research was carried out in the FMIPA greenhouse at Medan State University. The parameters tested were plant height, number of leaves, leaf area, wet weight and dry weight. The research results showed that the optimum dose of applying liquid organic fertilizer from Kepok banana stems to Samhong mustard greens was a concentration of 10%. Providing liquid organic fertilizer from kepok banana stems (Musa paradisiaca L.) had a significant effect on height growth, number of leaf blades, leaf area, wet weight and dry weight of Samhong mustard greens (Brassica juncea L.).

Abstract

Ketersediaan air bersih merupakan kebutuhan dasar untuk keberlangsungan hidup manusia dan menjadi prioritas dalam Pembangunan Berkelanjutan (SDGs), setiap individu berhak untuk mendapatkan akses air bersih yang sehat, mudah, terjangkau, dan memadai. Pertumbuhan populasi penduduk dan dampak perubahan iklim menjadi tantangan dalam pemenuhan ketersediaan dan kualitas air, baik di wilayah perkotaan maupun pedesaan. Nagari Durian Seribu, Kecamatan Silaut, Kabupaten Pesisir Selatan, menggunakan layanan air bersih dari sumur bor yang dikelola oleh PAMSIMAS melalui Badan Usaha Milik Nagari. Sejak Juni 2023 PAMSIMAS telah mengimplementasikan aplikasi berbasis Android untuk pencatatan digital pemakaian air, Berdasarkan data pencatatan pemakaian air yang terkumpul, pengelola ingin melihat perkembangan layanan yang diberikan, seperti total pemakaian air, total pendapatan, rata-rata pemakaian, rata-rata pendapatan, jumlah pelanggan, serta kinerja petugas lapangan secara periodik. Berdasarkan permasalahan tersebut maka penelitian ini bertujuan untuk mengembangkan sebuah Dashboard Visualisasi Data Penggunaan Air Bersih PAMSIMAS Nagari Durian Seribu. Dashboard menggunakan data pencatatan pemakaian air dari Juni 2023 hingga Juli 2024, Dashboard dibuat menggunakan Looker Studio dan Google Spreadsheet sebagai sumber data, dengan adanya dashboard ini dapat digunakan sebagai media untuk analisis perkembangan layanan PAMSIMAS dengan mudah, akurat, dan efisien bagi pengelola.
