Limbah tandan kosong kelapa sawit (TKKS) yang jumlahnya mencapai 23% dari tandan buah segar, mengandung unsur hara makro dan mikro yang penting bagi pertumbuhan tanaman. Pada saat ini limbah tersebut belum dimanfaatkan secara optimal. Tujuan penelitian ini adalah untuk mengembangkan dan menguji inokulum yang dapat digunakan untuk pembuatan kompos dari limbah tandan kosong kelapa sawit. Inokulum merupakan campuran bakteri dan jamur yang diisolasi dari limbah tandan kosong kelapa sawit. Isolat kemudian ditumbuhkan pada media pertumbuhan tertentu dan difermentasikan. Pengujian inokulum dilakukan pada skala laboratorium dengan cara sebagai berikut: dua kilogram tandan kosong kelapa sawit yang telah dicacah sepanjang  2 cm dimasukkan ke dalam wadah, kemudian diinokulasi dengan inokulum pada dosis 500 dan 1000 ml/ton. Percobaan diulang hingga tiga kali. Selama percobaan kelembaban relatif dijaga tetap 60% dan suhu diamati hingga proses pengomposan selesai. Kompos yang dihasilkan dianalisis kadar air, karbon, nitrogen, fosfor, kalium, dan magnesium. Pada penelitian ini telah berhasil dikembangkan inokulum yang terdiri atas campuran bakteri dan jamur dinamakan ”Indigenous Microbial Consortium” dan dapat dipergunakan untuk membuat kompos dengan kualitas yang memenuhi standar. Kata kunci: kompos, limbah tandan kosong kelapa sawit, inokulum, konsorsium mikroba. Empty palm oil bunch waste is about 23% of the fresh bunches which is rich with important macro and micro nutrients for plant growth. However, those have not been optimally utilized. The objective of this experiment was to develop and to evaluate the inoculums which could be used to make compost from empty palm oil bunch wastes. The inoculums consisted of fungies and bacteria isolated from the empty palm oil bunches. The isolates were then grown and fermented on to a particular media. The inoculums were then evaluated at laboratory scale according to the following methods. About 2 kg of 2 cm long crushed empty palm oil bunches were put in particular places and were then inoculated by the inoculums at a dosage of 500 and 1000 ml/ton of wastes. The experiment was done at triplicates and the relative humidity during the experiment was kept constant at 60%, and temperature was recorded until the end of the experiment. Water, carbon, nitrogen, phosphor, potassium, and magnesium contents of the composts were analysed. The inoculums that consisted of fungies and bacteria were successfully developed and it was called “Indigenous Microbial Consortium”. The inoculums could be used to make good quality of composts. Keywords: compost, empty palm oil bunches, inoculums, microbial consortium.

Systemic principles serve as the basic basis for thought and action processes, representing interconnected elements that contribute to the formation of a comprehensive whole. Bankruptcy law is a special and special law, regulated in Articles 222 to 294 of the Bankruptcy Law and PPU, PKPU is a legal peace institution whose operational elements include deciding judges, administrators, supervisory judges, debtors, creditors, and additional elements in the PKPU institution that are guarantors if provided. Systemically, these elements are interrelated both within their own elements and with theoretical elements, namely the Ideal elements (about meaning) and the actual elements. According to Article 287 of the Bankruptcy Law and PKPU Jo Article 282 of the Bankruptcy Law and PKPU, PKPU has a final and binding decision, but it is limited, and its decision is only related to the minutes of the meeting. The verdict still has legal consequences if violated. The author's motivation is to analyze systemic principles in the legal framework of PKPU peace institutions with the aim of upholding the principle of justice. The analysis methodology used is the legal system theory developed by Kees Schuit, focusing on the Ideal, Operational, and Actual elements. In addition, it incorporates three basic principles outlined by Gustav Radbruch – Certainty, Benefit, and Justice. The results of this study contribute prescriptive value to the field of law, especially in bankruptcy law.

Geographical Indication (GI) protection is a legal instrument within the intellectual property regime aimed at safeguarding products whose distinctive characteristics are inseparable from geographical factors and local wisdom. Bajawa Ikat Weaving from Ngada Regency, East Nusa Tenggara, has strong potential for GI protection due to its historical, philosophical and communal values inherited across generations. However, despite its cultural significance and economic potential, Bajawa Ikat Weaving has not obtained official GI registration, indicating a gap between legal potential and implementation. This study aims to analyze the legal framework governing GI protection for Bajawa Ikat Weaving under Law Number 20 of 2016 concerning Trademarks and Geographical Indications, identify implementation challenges and formulate strengthening strategies. This research applies a normative-empirical legal approach using statutory, conceptual and sociological methods. Data were collected through literature review and online in-depth interviews with three purposively selected informants: a local artisan, a regional government or MSME representative and a cultural figure or community representative in Ngada Regency. The findings indicate that GI is an appropriate legal mechanism for protecting Bajawa Ikat Weaving as communal traditional wealth. However, implementations remains constrained by weakness institutional capacity, limited product documentation, low legal awareness among artisans and product imitation risks. Comparative analysis with Gayo Coffee and Muntok White Pepper demonstrates that strengthening institutional governance, digital documentation and stakeholder coordination are essential to accelerate GI registration and ensure sustainable legal protection.
