Abstract

The aim of this study was to evaluate the performance of several Sorghum bicolor cultivars as forage on a dry land with pH of 5.4, N of 0.08%;  C/N of 9%, P of 0.06% and K of 0.01%. Nine cultivars of S. bicolor (Super 1, Super 2, Numbu, Kawali, G2, G5, PAC 537, PAC 593 and PAC 501) were evaluated. Plot size was 16 m2 with space planting of 15 x 75 cm. The experimental design used was randomized block design with three replications.  Parameters observed were plant height, time of flowering, forage production and quality. The result showed that the primary plant growth was not different in all cultivars. In the 65 days old primary plant,  the Super 2, PAC 537 and Kawali had no flower yet. Biomass production varied in primary plant between cultivars of 11.35 - 26.17 kg/16 m2. The highest biomass production was obtained in PAC 537 of 26.17 kg/16 m2 (16.34 t/ha) which were significantly higher than G2 of 11.35 kg/16 m2 (7.09 ton/ha) and was not significantly different with other cultivars. In the 45 days ratoon I, Super 2, G5 and Super 1 showed faster growth. Biomass production increased in the ratoon I around 19.88 kg/16 m2 (12.42 ton/ha). PAC 537 produced the highest biomass of 30.14 kg/16 m2 (18.84 ton/ha) and was not significantly different with other cultivars, except with the G2. Biomass production of ratoon II decreased around 1.83 kg/16 m2 (1.14 t/ha)–4.77 kg/16 m2 (2.98 t/ha) and increased in the ratoon III of 15.72 kg/16 m2 (9.82 t/ha)–26.05 kg/16 m2 (16.28 t/ha). The quality of forage ratoon I was better compared to the primary plant with the lowest one was in ratoon II. It could be concluded that Super 1, Super 2 and PAC 537 cultivars might be recommended as potential forage.

Abstract

Tanaman kerandang (Canavalia virosa) adalah jenis leguminosa yang banyak tumbuh dilahan salin (pantai). Indonesia merupakan negara kepulauan yang memiliki garis pantai yang panjang dan berpotensi apabila dikelola dengan baik seperti untuk penyediaan pakan ternak. Memelihara ternak merupakan alternatif diversifikasi usaha untuk meningkatkan taraf hidup nelayan pada saat tidak melaut. Tujuan penelitian untuk mengetahui produktivitas hijauan tanaman kerandang pada berbagai media tanah. Rancangan percobaan adalah split plot pola faktorial dengan faktor utama media tanam dan dosis pupuk limbah kopi. Perlakuan yang diuji adalah tanah, pasir kali dan pasir pantai, media tersebut diberi pupuk dengan dosis 0%, 5%, 10%, dan 15% yang diulang tiga kali. Parameter yang diamati produktivitas hijauan setiap 60 hari, pertumbuhan tanaman setiap minggu setelah panen. Hasil penelitian menunjukkan bahwa  produktivitas hijauan berat kering tertinggi pada media pasir kali 25,9 gram per panen pada dosis pemupukan 15%, kemudian diikuti pada media tanah 18,8 gram/tanaman/panen pada dosis 10%. Produksi terendah pada media pasir pantai 16,6 gram/tanaman/panen pada dosis 5%. Rataan produksi hijauan yang diberikan pupuk dibandingkan dengan perlakuan kontrol (0%) meningkatkan produksi 92,99%. Produksi hijauan tiap panen terjadi penurunan setelah pemotongan ke empat, sedangkan pada media pasir pantai pada awal produksi hijauan tertinggi kemudian panen berikutnya menunurun sampai panen kelima. Hasil penelitian ini disimpulkan bahwa tanaman kerandang dapat ditingkatkan produktivitasnya dengan pemberian pupuk organik dan setelah empat kali pemanenan perlu pemberian pupuk untuk mendapatkan hasil stabil.

Abstract

Legal certainty (rechtssicherheit) is a fundamental pillar of the Rule of Law, ensuring that legal provisions are clear, consistent, and predictable. In the Indonesian criminal justice system, the Public Prosecutor holds a central position as the Dominus Litis (the master of the suit), possessing the exclusive authority to determine which cases proceed to court. However, the current implementation of prosecutorial authority often leans towards rigid legal positivism, creating a paradox where procedural certainty is achieved at the expense of substantive justice. Disparities in prosecution demands for similar crimes often lead to public distrust and legal uncertainty for justice seekers. Furthermore, prosecutors often lack the cognitive flexibility to handle complex cases that require discretionary wisdom. This study aims to analyze the challenges in maintaining legal certainty and proposes a strategy to enhance the prosecutor's role through the integration of Restorative Justice and a reform in prosecutorial competency. The research employs a normative juridical method with statutory and conceptual approaches, analyzing Attorney General Regulation No. 15 of 2020. The study finds that enhancing legal certainty requires shifting the paradigm from "mechanical prosecution" to "discretionary prosecution" based on conscience. To achieve this, prosecutors must be equipped with high-level cognitive skills specifically "Creative Thinking" to interpret "certainty" not just as textual compliance, but as the consistent application of fairness.
