The effectiveness of law as a tool for social construction should ideally enhance our societal framework and address the challenges of the evolving era. However, contemporary observations reveal a growing lack of trust in the legal system. Critics point to perceived deficiencies in the quality of laws as agents of social construction and in achieving substantive justice. Moreover, a palpable anxiety surrounding a legitimacy crisis is evident. The role of law as a medium for social construction, aiming to establish a just and prosperous society, faces considerable resistance. Understanding the root causes behind society's struggle to interpret and embrace the purpose of law as a social construction instrument becomes imperative. The inadequate level of legal awareness among the populace is closely linked to issues such as educational disparities. The existing education systems, patterns of regulatory socialization, and restricted public access to information contribute to a diminished recognition of the importance of law. Addressing these challenges necessitates a focus on education as a viable solution. By elevating legal awareness, it is anticipated that the propensity for individuals to contravene the law would diminish. Therefore, investing in public education emerges as a promising strategy to foster the realization of a modern, constructively developed society.

The scarcity of fuel oil in the future needs to be anticipated by preparing alternative energy. One of the alternative energy sources developed is Jatropha. However, the development of Jatropha should use marginal land as a cultivation area, like a dry land, because the food crops and horticulture use productive land for cultivation. Furthermore, Jatropha development through breeding is an effort to obtain superior varieties as biodiesel producers. This study aimed to determine the best phenotype characteristics of hybrid Jatropha plants as superior candidate trees. This research applied a descriptive qualitative method to determine the characteristics of Jatropha crossing results. The Jatropha characterization was conducted at the experimental garden of Kedung Pengaron Village, Kejayan Sub-district, Pasuruan Regency. The experimental garden was included dry land for Jatropha cultivation. The result showed ten selected genotypes of hybrid Jatropha were found, including 05.01.01, 05.01.02, 05.02.02, 05.02.09, 05.03.17, 05.03.16, 05.04.16, 05.04.15, 06.01.02, 06.01.15. These were based on the two-phase observations, consisting of vegetative and generative observations. The plants’ morphological characters were observed, comprising the stems, leaves, flowers, fruits and seeds. In the vegetative phase, diversity was found in the number of leaves, leaf length and age of flowering, while in the qualitative phase, the shoot colors were more diverse. Moreover, less variations were figured out in the color character of the petiole and the number of shoots. These ten genotypes of hybrid Jatropha are the best genotypes that are resistant to drought with selected agronomic characters.

Tujuan peneitian ini adalah untuk mengetahui bagaimana perlindungan terhadap konsumen yang menggunakan jasa escrow dalam melakukan transaksi jual beli online dilihat dari hukum positif melalui undang-undang perlindungan konsumen, undang-undang informasi dan transaksi elektronik, peraturan pemerintah tentang penyelenggaraan sistem transaksi elektronik dan undang-undang perdagangan. Sedangkan melalui hukum islam melalui Muamalah, Samsarah, Al-Ba’i, Perikatan Islam dan Khiyar.Penelitian ini menggunakan jenis penelitian hukum normatif, serta menggunakan sumber bahan hukum primer berupa Al-Qur’an, Hadis, Fikih, hasil Ijtihad ulama, Undang-Undang Nomor 08 Tahun 1999 tentang Perlindungan Konsumen, Undang - Undang Nomor 11 Tahun 2008 tentang Informasi dan Transaksi Elektronik, Peraturan Pemerintah Nomer 82 Tahun 2012 tentang Penyelenggaraan Sistem dan Transaksi Elektronik, Undang - Undang Nomor 7 Tahun 2014 tentang Perdagangan. Bahan hukum sekunder seperti pendapat ahli hukum, teori, hasil karya dari kalangan hukum, penelusuran internet, artikel ilmiah, jurnal, dan makalah. Sedangkan bahan hukum tersier berupa kamus, ensiklopedia dan sebagainya.Hasil dari penelitian ini menunjukan bahwa Perlindungan Hukum Terhadap Konsumen dalam Praktik Jual Beli Online dengan Jasa Escrow Menurut Hukum Positif Dan Hukum Islam sudah sangat baik dilakukan oleh toko online penyedia jasa escrow, hal ini berdasarkan isi syarat dan ketentuan dari toko online yang sesuai dengan pasal-pasal yang ada dalam Undang-Undang Nomor 08 Tahun 1999 tentang Perlindungan Konsumen, Undang - Undang Nomor 11 Tahun 2008 tentang Informasi dan Transaksi Elektronik, Peraturan Pemerintah Nomer 82 Tahun 2012 tentang Penyelenggaraan Sistem dan Transaksi Elektronik, Undang - Undang Nomor 7 Tahun 2014 tentang Perdagangan. Namun dari 6 tujuan perlindungan konsumen ada 1 poin yang tidak terpenuhi karena penyedia jasa toko online membuat standart contract untung melepaskan tanggung jawab mengganti kerugian penggunanya. Begitu pula dalam hukum Islam, standart contract tentang pelepasan tanggung jawab tidak sesuai dengan prinsip keadilan dalam muamalah.

This article discusses trademarks in a legal political perspective. The existence of Presidential Regulation No. 63 of 2019 concerning the Use of Indonesian which regulates the use of Indonesian that must be used on trademarks owned by Indonesian citizens or Indonesian legal entities has conflicts with the Law Number 20 of 2016 On Trademarks and Geographical Indications, regarding the function and purpose of the Trademarks, so it is interesting to conduct discussions through normative juridical methods. The results of this study show that the principle of Lex Superior Derogat Lex Inferiori law, which is a principle that interprets higher legal norms, can be used as one of the tools in solving problems. Thus, the position of Presidential Regulation Number 63 of 2019, is no more binding than the position and binding power of Law Number 20 of 2016 on Trademarks and Geographical Indications. Abstrak Artikel ini membahas merek dagang dalam perspektif politik hukum. Keberadaan Peraturan Presiden Nomor 63 Tahun 2019 tentang Penggunaan Bahasa Indonesia yang mengatur penggunaan bahasa Indonesia yang harus digunakan pada merek dagang milik warga negara Indonesia atau badan hukum Indonesia bertentangan dengan Undang-Undang Nomor 20 Tahun 2016 tentang Merek Dagang dan Indikasi Geografis, mengenai fungsi dan tujuan Merek Dagang, sehingga menarik untuk melakukan diskusi melalui metode yuridis normatif. Hasil penelitian ini menunjukkan bahwa prinsip hukum Lex Superior Derogat Lex Inferiori, yang merupakan prinsip yang menafsirkan norma hukum yang lebih tinggi, dapat digunakan sebagai salah satu alat dalam memecahkan masalah. Hal ini berimplikasi kedudukan Peraturan Presiden Nomor 63 Tahun 2019, tidak lebih mengikat dengan kedudukan dan daya mengikat Undang-Undang Nomor 20 Tahun 2016 Tentang Merek Dagang dan Indikasi Geografis.

The use of herbicides is one of the most widely used chemicals in the oil palm industry. The chemical that used continuously and in large quantities in oil palm plantation certainly has a negative impact on the environment, especially spray workers who are directly exposed to chemicals. Therefore, it is necessary to find out how to reduce the hazardous from excessive use of chemicals. WEED Solut-ioN® with active ingredient of 2-Sodium Amine is a new product that it is claimed to reduce herbicide doses without reducing its effectiveness. The objective of this trial is to determine the efficacy of herbicide (or cocktails of herbicides) + reductant WEED Solut- ioN® and compared to herbicides (or cocktails of herbicides) (without reductant WEED Solut- ioN®) in controlling weeds in Teladan Prima Agro Tbk. (TPA) estates. The dose treatment of Isopropilamyne glyphosate + Methyl metsulfruron combined with WEED Solut-ioN® (doses 50:50) was not significantly different to control. Other results showed that there was not significantly different between Fluroxipir (with or without sticker) combined with WEED Solut-ioN® (doses 50:50) as well as Ammonium glufosinate combined with WEED Solut-ioN® (doses 50:50). The use of WEED Solut-ioN® (doses 50:50) that are able to reduce the use of herbicide volume can certainly reduce the cost of using herbicides. Keywords: oil palm, weed control, herbicides, reductant, weed solut- ion, cost efficiency
