Abstract

Penelitian ini bertujuan untuk menganalisis kesalahan siswa dalam menyelesaikan masalah geometri, khususnya bangun ruang sisi datar, berdasarkan teori Kastolan dengan memperhatikan perbedaan gaya belajar visual, auditori, dan kinestetik. Metode yang digunakan adalah deskriptif kualitatif dengan sembilan siswa kelas VIII SMP Negeri 2 Gresik sebagai subjek yang dipilih secara purposive, masing-masing mewakili kategori gaya belajar. Data dikumpulkan melalui tes tertulis satu butir soal dan wawancara mendalam untuk menggali proses berpikir siswa serta keterkaitannya dengan gaya belajar. Analisis data dilakukan melalui tahapan reduksi, penyajian, dan penarikan kesimpulan dengan mengacu pada indikator kesalahan Kastolan yang meliputi kesalahan konseptual, prosedural, dan teknik. Hasil penelitian menunjukkan bahwa siswa dengan gaya belajar visual cenderung tidak melakukan kesalahan prosedural, tetapi sering mengalami kesalahan konseptual dan teknis, seperti keliru menuliskan satuan volume. Siswa kinestetik memperlihatkan variasi kesalahan yang lebih kompleks, bahkan ada yang melakukan ketiga jenis kesalahan sekaligus. Sementara itu, siswa auditori cenderung melakukan kesalahan prosedural akibat salah menafsirkan informasi dalam soal serta kesalahan teknis akibat kurang teliti. Secara keseluruhan, kesalahan konseptual menjadi temuan yang paling dominan, menandakan lemahnya pemahaman dasar siswa terhadap konsep geometri. Simpulan penelitian ini menegaskan pentingnya intervensi pembelajaran yang tidak hanya menekankan penguasaan konsep, tetapi juga pembiasaan prosedural dan ketelitian teknis sesuai gaya belajar siswa.

Abstract

This research aims to determine the best dose of KCl fertilizer and humic acid for peanut yields. The study was conducted using a split-plot design with two factors, and each factor was repeated three times. The dose of KCl as a subplot consisted of 4 levels (0, 50, 75, and 100 kg/ha), while humic acid as the main plot consisted of 4 levels (0, 10, 20, and 30 kg/ha). Observation included the number of non-productive gynophores, the number of pods, dry weight harvest yield (pods per plant, pods per plot, seeds per plant, and seeds per plot), and the weight of 100 seeds. The single factor of KCl dosage significantly affected the dry weight of pods per plant, dry weight of seeds per plant, and dry weight of seeds per plot. The single factor of humic acid treatment had no significant effect on all observation variables, while the interaction of KCl and humic acid doses significantly affected the number of non productive gynophores and the weight of 100 seeds. The best dosage was 100 kg/ha, producing the highest yield with a dry seed weight per plot of 147.43 g. The combination of KCl 75 kg/ha and humic acid 30 kg/ha produced peanuts with the best quality, with weight 100 seeds of 39.47 g. Keywords: Humic acid, KCl, Peanut, Potassium, Yield.

Abstract

The quality of soybean seeds, encompassing physical, physiological, and chemical attributes, is crucial for successful plant growth and yield. Effective seed storage is vital in maintaining seed viability, growth capacity, and adaptability, especially amid global challenges like climate change and rising food demand. This research aimed to identify the optimal packaging material and storage temperature to preserve soybean seed quality. Using a Split Plot Design with two factors and three replications, the study examined four storage temperatures (S0: 27.1°C, S1: 7-10°C, S2: 17-19°C, S3: 20-25°C) and three packaging types (K1: plastic-coated sack, K2: PE plastic, K3: aluminum foil). Results indicated that seeds stored at 27.1°C in plastic-coated sacks experienced increased moisture, reduced vigor, slower growth, lower germination, and altered protein and fat content. Conversely, PE plastic and aluminum foil packaging maintained seed quality over three months. All packaging types effectively preserved seed quality at cooler temperatures (7-25°C). This study underscores the importance of optimal storage conditions for sustainable soybean seed availability. Keywords: Packaging, Seed Quality, Soybean Seeds, Storage, Temperature.

Abstract

Melon (Cucumis melo L.) is a fruit known for its sweet and refreshing taste. Traditionally, melon cultivation has relied on conventional farming methods. The use of biofertilizers offers an alternative to reduce dependency on synthetic fertilizers. This study aimed to enhance the production of healthy, high-yielding melon plants by substituting Mutiara NPK fertilizer with Bioto Grow Gold (BGG) biofertilizer. Conducted in Sukosongo Village, Kembangbau District, Lamongan Regency, East Java, the experiment employed a factorial Completely Randomized Design (CRD).Two factors were tested: BGG fertilizer at four concentrations (0 ml/L [P0], 1 ml/L [P1], 2 ml/L [P2], and 4 ml/L [P3]) and NPK fertilizer at four doses (0 g/plant [N0], 60 g/plant [N1], 70 g/plant [N2], and 80 g/plant [N3]). Results indicated that BGG fertilizer influenced both vegetative and generative growth variables, as did the Mutiara NPK fertilizer doses. The optimal combination was achieved with a BGG concentration of 3 ml/L and an NPK dose of 70 g/plant, which significantly increased the sucrose content in melons. Keywords: Bioto Grow Gold fertilizer, Biofertilizer, Melon, NPK Mutiara fertilizer.
