Abstract

Abstrak. Terdapat permasalahan dan kendala produksi padi (Oryza sativa L.) seperti luas lahan yang semakin sempit juga sistem budidaya yang masih tradisional. Sawah dataran medium dapat dijadikan perluasan lahan meskipun suhu lebih rendah dibandingkan dataran rendah yang menyebabkan pertumbuhan dan hasil rendah. Perlakuan sistem tanam Legowo dengan penggunaan kultivar unggul diharapkan mampu meningkatkan hasil padi di dataran medium. Penelitian ini bertujuan untuk mempelajari interaksi dari sistem tanam Legowodengan benih padi kultivar unggul (Ciherang, IR64, dan Mekongga). Penelitian dilaksanakan pada bulan Desember 2019 – Mei 2020 di lahan persawahan Bojongsoang, Kab. Bandung, Jawa Barat dengan ketinggian 662 meter di atas permukaan laut. Metode yang digunakan dalam penelitian ini adalah eksperimen dengan rancangan penelitian adalah rancangan petak terbagi, yang terdiri dari dua faktor dan tiga ulangan. Faktor pertama yaitu kultivar padi (Ciherang, IR64, dan Mekongga) sebagai petak utama, sementara faktor kedua yaitu sistem tanam (tegel, Legowo 2:1, Legowo 4:1 tipe 1, dan Legowo 4:1 tipe 2) sebagai anak petak. Hasil penelitian menunjukkan bahwa terdapat interaksi antara perlakuan sistem jajar Legowo dan kultivar unggul padi terhadap konduktan stomata dan tinggi tanaman pada umur 6 minggu setelah tanam. Kombinasi sistem Legowo 2:1 dengan kultivar unggul Ciherang memiliki hasil paling tinggi 11,63 kg per petak atau setara dengan 9,69 ton per hektar.Kata Kunci: Ciherang, IR64, Kultivar unggul, Mekongga, Padi, Sistem tanam jajar Legowo Abstract. There are problems on rice production (Oryza sativa L.) such as decreasing land area and the traditional cultivation system. Medium land rice fields can be used as land expansion even though its temperature is lower than the lowlands which causes low growth and yields. The treatment of the row systems with the use of superior cultivars was expected to increase rice yields in medium land. This study aims to study the interaction of the row system with superior cultivar rice seeds (Ciherang, IR64, and Mekongga). The research was conducted in December 2019 - May 2020 in the Bojongsoang rice fields, Bandung, West Java with an altitude of 662 meters above sea level. The method used experimental whose design was a split plot design. The treatment consisted of two factors and three replications. The first factor was rice cultivars (Ciherang, IR64, and Mekongga) as the main plot, while the second factor was the row systems (squares, Legowo 2:1, Legowo 4:1 type 1, and Legowo 4:1 type 2) as subplots. The results showed that there was an interaction between the Legowo row system treatment and superior rice cultivars on the stomatal conductance and plant height at 6 weeks after planting. The combination of the Legowo 2:1 system with the superior cultivar of Ciherang had the best yield of 11.63 kg per plot or the equivalent of 9.69 tonnes per hectare.Keywords: Ciherang, High-yield cultivars, IR64, Jajar Legowo row system, Mekongga, Rice

Abstract

The development of high-yielding hybrid maize is a strategic step to address global food demand amidst climate change. This study evaluates the agronomic performance of 14 maize genotypes—10 newly developed F1 hybrids and 4 commercial checks—under two planting densities (95,000 and 55,000 plants/ha) across three agroecosystems (lowland, midland, and highland). The objectives were to identify superior and adaptive genotypes and analyze genotype × environment interactions using AMMI and GGE biplot methods. Genotype G12 exhibited the highest yield (338.4 g/plant) at high density, especially in the highland, but showed poor stability. In contrast, G5 demonstrated consistent performance and stability across environments. This study highlights G5’s potential for broad adaptation and provides insights for breeding programs targeting maize productivity in diverse agroecosystems.

Abstract

Penelitian ini bertujuan untuk menguji dan menganalisis factor-faktor yang mempengaruhi keputusan pembelian. Sampel yang digunakan dalam penelitian ini sebanyak 204 responden dengan menggunakan metode penarikan sampel purposive sampling. Sampel yang digunakan dalam penelitian ini adalah konsumen yang merupakan pengguna e-commerce di DKI Jakarta. Pengujian hipotesis dilakukan dengan metode regresi berganda (multiple regression) dengan bantuan software SPSS versi 21. Hasil dari penelitian ini menunjukkan bahwa terdapat pengaruh positif online customer review terhadap keputusan pembelian dan terdapat pengaruh positif celebrity endorsement terhadap keputusan pembelian. Adapun saran bagi penelitian selanjutnya agar dapat menambahkan factor lain yang dapat memperngaruhi keputusan pembelian konsumen yang merupakan pengguna e-commerce

Abstract

Introduction: The enactment of Law Number 17 of 2023 concerning Health has brought a paradigm shift in the arrangement of therapeutic agreements between health workers and patients.Purposes of the Research: This study aims to analyze the binding power of therapeutic agreements by focusing on the legal position of the exoneration clause in informed consent and examining the form of settlement for patient losses.Methods of the Research: Using normative legal research methods with Statute approach and conceptual approach.Results Main Findings of the Research: This study reveals that therapeutic agreements have binding power based on the principle of adequate informed consent. However, the exoneration clause in informed consent faces stricter legal restrictions based on Law Number 17 of 2023, especially related to the expanded responsibility of hospitals. The research concludes that the binding power of therapeutic agreements must be balanced with the protection of patients' rights, and effective dispute resolution mechanisms are needed to ensure fairness for all parties.
