Authors: Bogar Antonius , Ukas Ukas 
Published: February 2022

The Indonesian Manpower Law act Number 13 of 2003 concerning Manpower regulates in detail the termination of employment (PHK) as well as legal protection for workers who are laid off. In terms of employment, which is a critical issue at this time is the Termination of Employment (PHK) of workers/laborers because companies are hit by the Covid-19 Pandemic. This research includes normative legal research with a statutory approach and in the analysis of legal materials using qualitative descriptive techniques. In this study, the main problem that the author examined is the legal basis for dismissal based on the Covid-19 Pandemic and the legal consequences for workers who work under a work agreement (PKWT). Based on the research problems and methods, the results of this study found that the termination of employment (PHK) committed against workers since the Covid-19 pandemic was a violation, therefore it is an act against the law and against the law. As a consequence, the company is obliged to pay the rights of workers/labor in accordance with the provisions and regulations of the prevailing laws.How to cite item: Bogar, A., Ukas, U. (2021).

Published: February 2022

Over the past 20 years, the area under maize has grown by 290 %. The production of grain corn is associated with the formation of a large amount of biological mass, which after harvesting remains in the field in the form of an aboveground dry mass of a plant and an underground powerful root system. The amount of crop residues per hectare after harvesting corn for grain reaches 10-15 tons. To prepare such a field for further operation, it is necessary to prepare the crop residues of corn for the destruction process. The technical means of mechanical processing of stubble-root residues of domestic and imported corn with an analysis of the design features of the working bodies are considered.

Authors: Kirdey Tatiana Aleksandrovna 
Published: February 2022

Salinity is one of the chief factors of soil fertility decreasing and soil degradation. The influence of lowland peat humus acids preparation on spring wheat (Triticum aestivum L.) resistance to progressing chlorine salinity was investigated. The plants were grown in aquatic culture on Hogland nutrient mixture. The progressing salinity was created with the help of NaCl concentration from 25 to 100 mM by 25 Mm step every 14 days. Variants of permanent salinity included 75 and 100 mM. In all the variants of the experiment the plants were grown with addition of peat humus acids preparation (0,005%) or without it. In the result of the experiment it was stated that humic acids protective action is more manifested under strong stress influence, NaCl permanent concentration being 100 Mm, herewith the degree of plants salinity resistance in presence of humic acids increases 1,5-2 times. Under progressing salinity humic acids preparation protective action is observed only on the 14-th (25Mm) and 28-th (50 Mm) days after salinity beginning. Peat humic acids preparation was found to decrease Sodium accumulation in wheat shoots almost twice under progressing salinity up to 100Mm and 2,3-2,7 times in the variants of permanent salinity.

Pengolahan tanah merupakan kegiatan yang bertujuan untuk mendapatkan kondisi tanah yang baik. Kondisi tanah yang baik dimanfaatkan sebagai media tumbuh bagi berbagai jenis tanaman dan pembangan akarnya. Salah satu indikator tanah yang baik adalah tingkat kesuburannya. Kesuburan tanah adalah kemampuan suatu tanah untuk menyediakan unsur hara bagi tanaman. Beberapa proses yang dapat dilakukan untuk menjaga kesuburan tanah adalah upaya penggemburan tanah. Penggemburan tanah umumnya dilakukan pada lahan-lahan yang kering dan padat dan biasanya petani masih menggunakan alat tradisional untuk mengolah tanah tersebut. Penggunaan alat tradisional tentu akan mengurangi tingkat produktivitas karena memerlukan waktu, tenaga, dan biaya yang cukup tinggi. Oleh karena itu, perlu adanya alat atau mesin yang dapat digunakan untuk mengganti alat-alat tradisional tersebut. Tujuan dari penelitian ini adalah merancang mesin penggembur tanah dengan memanfaatkan mesin potong rumput sebagai motor penggerak. Mesin ini dilengkapi dengan bajak singkal dan bajak rotary. Pengujian mesin dilakukan pada lahan kering dengan luasan 30 m2. Berdasarkan hasil penelitian dan pengujian diketahui bahwa mesin penggembur tanah dengan motor penggerak mesin potong rumput memiliki kinerja sekitar 0,115 m2/detik atau setara dengan 414 m2/jam. Kinerja mesin masih tergolong kecil karena beberapa faktor diantaranya dimensi bajak rotary yang kecil dan putaran yang terlalu cepat. Oleh karena itu, perlu adanya modifikasi dan pengembangan yang lebih optimal sehingga mesin ini diharapkan dapat dimanfaatkan oleh masyarakat untuk meningkatkan produktivitasnya.
Peran Gereja dalam Penegakan Hak Asasi Manusia di tengah Keberagamaan

Published: February 2022

Violations of human rights in the religion of these days are increasingly rampant, where most violations cannot be categorized by mild violations, but some have entered anarchist actions. This violated Article 22 of Law Number 39 of 1999 concerning Human Rights. So that if the violation is tolerated or allowed to continue to occur, the image of the country which is a sovereign entity for the orderly of the social society based on the law is not well-reflected. So in this journal, the authors reveal from personal perspectives and based on experience in living in the midst of a compound society how human rights violations in religion often occur. And hope that all efforts can be done optimally so that Indonesia will again become a fair, sovereign, and back to the spirit of unity. And the church must provide examples of exemptions to protect and respect human rights because the church believes human rights are derived from God (Gen. 1: 26-27). AbstrakPelanggaran Hak Asasi Manusia dalam keberagamaan hari-hari ini semakin marak terjadi, dimana pelanggaran tersebut kebanyakan tidak bisa dikategorikan pelanggaran ringan, tetapi beberapa sudah masuk tindakan anarkis. hal itu melanggar Pasal 22 Undang-Undang Nomor 39 Tahun 1999 tentang Hak Asasi Manusia. Sehingga jika pelanggaran tersebut ditolerir atau dibiarkan terus terjadi maka citra negara yang merupakan entitas yang berdaulat atas tertib sosial masyarakat berdasarkan hukum tidak tercermin dengan baik. Maka dalam jurnal ini penulis mengungkap dari perspektif pribadi dan berdasarkan pengalaman dalam hidup ditengah masyarakat yang majemuk bagaimana pelanggaran-pelanggaran HAM dalam keberagamaan kerap terjadi. Dan berharap agar segala upaya bisa dilakukan dengan maksimal agar Indonesia kembali menjadi negara yang adil, berdaulat dan kembali memiliki semangat persatuan. Serta gereja harus memberikan contoh teladan bagimana melindungi dan menghormati HAM karena gereja percaya HAM adalah berasal daripada Tuhan (Kej 1: 26-27).
