Abstract

Cauliflower (Brassica oleracea var. botrytis L.) during its development period needs to be controlled by pests and diseases, because at that time the flowers or krobs come out and will determine the quality and quantity of its production. This research is conducted to characterize and differentiate various types of pests and diseases found in cauliflower plants in the gardens of Gonaman Village, Koripan, Matesih District, Karanganyar. This research employs a methodology based on descriptive qualitative analysis. The tools utilized in this study include a mobile phone, writing instruments, and observation sheets. The research subjects consist of various pests and diseases identified in the garden area. Data collection by observation of the garden and direct interviews with garden owners. For data analysis and validation, qualitative descriptive techniques are used with additional interview activities with cauliflower farmers and literature studies. Based on the results of the study, eight pests have been found, namely; Whitefly / Cabuk (Aphis brassicae), Thrips (Thrips tabasi), Whitefly (Aleyrodidae sp), Crop Caterpillar (Crocidolomia binotalis), Ladybug (Illeis galbula), Brown grasshopper (Valanga nigricornis), Leaf beetle (Aluacphora sp), Leaf caterpillar (Plutella xylostella). And four diseases were found; Alternaria brassicae fungus, bacterial rot by Pectobacterium carotovorum, Erwinnia carotovora bacteria, and Xanthomonas camprestis bacteria. The visible symptoms are damage to the leaves, yellow, brownish to blackish leaves, rotten and wilted flowers so that they can reduce the harvest. Pest and disease control can be done by spraying pesticides, fungicides once a week, maintaining land cleanliness, maintaining planting distance, selecting healthy seeds, and providing lime and boren. For further research, it should be done for several days, in the morning and evening when insects are active.

Abstract

Chili is a type of plant that is consumed almost every day by almost all of the world's population. Increasing the yield of chili plants will ensure the availability of chilies on the market. One effort to increase the amount of chili production is by choosing the right fertilizer based on the type of chili planted. In this review article, we discuss the influence of chemical and or non-chemical fertilizer types which are related to physiological aspects, for example the number of leaves, plant height, and total chlorophyll content. By knowing a lot of information regarding fertilization of chili plants, it is hoped that it can help in efforts to increase production so that it can meet people's needs for chilies.

Abstract

Pengukuran keterampilan berargumentasi diperlukan untuk mengetahui profil keterampilan berargumentasi mahasiswa pada isu socioscientific. Tujuan penelitian ini adalah untuk mengkonstruksi dan memvalidasi isi instrumen keterampilan berargumentasi berbasis socioscientific issues (socioscientific argumentation skills) pada topik hutan mangrove mata kuliah Ekologi Tumbuhan di Universitas Veteran Bangun Nusantara. Penelitian ini merupakan bagian dari penelitian pengembangan yaitu perancangan dan pengembangan produk awal.  Konstruksi instrumen keterampilan berargumenasi berbasis socioscientific issues dilakukan dengan kajian literatur untuk menentukan dimensi dan indikator keterampilan berargumentasi. Proses validasi isi dari instrumen tes menggunakan metode Delphi. Validasi isi menggunakan 13 validator ahli instrumen evaluasi dan hasil dari skor yang diberikan oleh masing-masing validator selanjutnya dilakukan perhitungan dengan menggunakan koefisien validitas Aiken. Aspek yang dinilai antara lain : materi, konstruksi dan bahasa. Hasil konstruksi instrumen tes menunjukkan bahwa socioscientific argumentation skills mencakup aspek-aspek claim, evidence, reasoning, contemplation dan disusun menjadi 6 indikator serta 8 soal tes essai. Hasil validasi isi oleh 13 validator ahli dengan perhitungan Aiken menunjukkan bahwa 8 soal tes semua valid. Instrumen tes socioscientific argumentation skills yang sudah valid ditinjau dari validitas isi perlu dilanjutkan dengan uji validitas konstruk.

Abstract

Biology learning at the high school level requires teaching resources that can connect theoretical concepts with real phenomena so that students gain more meaningful learning experiences. This study aimed to identify the morphological diversity of citrus fruits sold at Gede Market Solo and assess their potential as a locally based biology learning resource. Data collection was carried out through direct observation by randomly selecting 14 types of citrus fruits from several vendors, documenting their morphological characteristics through photographs, and conducting brief interviews to obtain additional information related to each fruit type. The data were then descriptively analyzed based on several morphological indicators, namely, skin color, skin texture, skin thickness, fruit diameter, fruit shape, and flesh color. The results showed that Pasar Gede Solo contains a highly diverse range of citrus fruits with clear morphological variations across categories and species. These variations enable citrus fruits to be used as real objects in identification and classification activities within biodiversity lessons, allowing students to engage in direct observation and understand concepts more contextually. The diversity of citrus fruits also provides opportunities for students to practice scientific process skills through activities such as observation, recording, comparison, and analysis of morphological features. These findings demonstrate that utilizing locally available citrus fruits can enrich biology learning, strengthen conceptual understanding, foster critical thinking, and cultivate students’ awareness of local biodiversity. This study explicitly highlights the use of morphological diversity of citrus fruits in a traditional market as a contextual and locally based biology learning resource, which has rarely been explored in previous biodiversity learning studies.

Abstract

This study aims to explore and compare the daily behavioral patterns of purebred Himalayan cats and domestic (corner) cats (Felis catus) within a shared environmental context. Observations were carried out in Kesongo Hamlet, Sukoharjo Regency, employing scan sampling and ad libitum techniques over a three-week period. Recorded behaviors were classified into affiliative, self-maintenance, and negative categories. The findings revealed that Himalayan cats demonstrated a higher frequency of affiliative behaviors, including feeding, autogrooming, and approaching humans indicating a predisposition to emotional bonding and a preference for stable domestic settings. Conversely, domestic cats primarily exhibited self-maintenance behaviors such as roaming and climbing, reflecting stronger adaptive traits and instinctual responses to dynamic environments. Negative behaviors were relatively rare in both groups; however, aggressive tendencies were more commonly observed in domestic cats. These results underscore the influence of both genetic predispositions and environmental conditions in shaping feline behavior. The study offers valuable contributions to the field of ethology and provides practical insights for enhancing feline welfare by addressing breed-specific behavioral needs.
