Abstract

Maharani Zoo & Goa di Kabupaten Lamongan memiliki permasalahan utama yaitu pembuangan kotoran hewan gajah dan hewan lainnya dalam jumlah yang relatif besar yaitu ±30 ton per bulan. Permasalahan limbah bolga ini belum mendapatkan solusi optimal sehingga hanya ditimbun di lokasi khusus tanpa adanya pengolahan lebih lanjut. Oleh karena itu, program ini bertujuan untuk mengolah potensi limbah kotoran gajah atau bolga menjadi produk-produk bernilai ekonomis dengan memanfaatkan teknologi dalam rangka mendukung program green economy. Metode yang digunakan dalam pengolahan bolga adalah menggunakan proses pirolisis untuk pembuatan produk briket dan pupuk organik padat, serta proses fermentasi untuk pembuatan pupuk organik cair. Adapun hasil dari kegiatan ini antara lain produk briket, pupuk organik padat dan pupuk organik cair, kerjasama antara perguruan tinggi dengan mitra, serta dokumen SOP pengolahan bolga. Sehingga dapat disimpulkan bahwa proses pengolahan bolga menjadi tiga produk tersebut telah membantu mitra mengatasi permasalahan limbah kotoran hewan.

Abstract

Indonesia menduduki posisi ke dua setelah cina penghasil sampah plastik terbesar di dunia. Dimana salah satu limbah plastik tersebut adalah HDPE (High Density Polyethylene). Sedangkan plastik merupakan produk hasil pengolahan minyak bumi yang dapat direcycle ke bentuk semulanya karena bahan baku pembuatan limbah plastik adalah nafta yang merupakan salah satu unsur dari minyak bumi. Salah satu solusi yang diperlukan adalah recycle dengan mengubah limbah plastik menjadi bahan bakar dengan proses pirolisis. Pirolisis merupakan salah satu proses terbaik dari recycle limbah plastik, dengan pertimbangan memahami sifat limbah plastik HDPE. Penelitian ini menggunakan alat pirolisis dengan variable suhu proses yaitu 300⸰C, 325⸰C, dan 350⸰C, waktu proses pirolisis yaitu 2 dan 4 jam. Dari proses pirolisis diperoleh hasil volume bahan bakar diesel yaitu pada suhu 300⸰C sebanyak 95 ml, suhu 325⸰C sebanyak 100 ml, dan suhu 350⸰C sebanyak 145 ml. Dari hasil analisa data optimal  untuk suhu dan waktu optimum proses pirolisis limbah plastik HDPE yaitu pada suhu 325⸰C selama 2 jam, bahan bakar diesel yang didapat memiliki kadar abu 0,044 (b/b), dan kadar air 0,031(%vol). ABSTRACTIndonesia is in second place after China, the largest plastic waste producer in the world. Where one of the plastic wastes is HDPE (High-Density Polyethylene). Meanwhile, plastic is a product of petroleum processing that can be recycled to its original form because the raw material for making plastic waste is naphtha, which is an element of petroleum. One solution that is needed to recycle by converting plastic waste into fuel by the pyrolysis process. Pyrolysis is one of the best processes for recycling plastic waste, with consideration of understanding the nature of HDPE plastic waste. This study used a pyrolysis tool with process temperature variables, namely 300⸰C, 325⸰C, and 350⸰C, the pyrolysis process time was 2 and 4 hours. From the pyrolysis process, the results of the volume of diesel fuel are at a temperature of 300 ⸰C as much as 95 ml, a temperature of 325 C as much as 100 ml, and a temperature of 350 ⸰C as much as 145 ml. From the results of the optimal data analysis for the optimum temperature and time of the HDPE plastic waste pyrolysis process, which is at a temperature of 325⸰C for 2 hours, the obtained diesel fuel has an ash content of 0.044 (w / w), and a moisture content of 0.031 (vol%).

Abstract

E-commerce is a trade transaction that allows buying and selling without having to meet directly between the seller and the buyer. This trading system requires a strong sense of trust between one another, between sellers and buyers. Recognition of electronic evidence as evidence that can be submitted to court and recognized as valid evidence has been carried out since 1977 through the Company Documents Act which stipulates that microfilm containing recordings of company documents can be submitted as evidence in court if it arises in the future. lawsuit. According to the Company Documents Law, electronic document evidence is part of documentary evidence, while the Corruption Law explicitly explains that electronic information and electronic documents are an extension of demonstrative evidence. Because electronic letters in the form of electronic information or electronic documents have been recognized as one of the legal means of evidence in special crimes outside the Criminal Code, parallel to the legal evidence in Article 184 of the Criminal Procedure Code, which is a new type of evidence, it is hoped that investigators, public prosecutors, advisers law and judges have an understanding of this electronic evidence. In examining criminal cases, it is hoped that the judge will impose a sentence based on two valid pieces of evidence and the judge will gain confidence that it is the defendant who is guilty of committing a crime, so the judge must impose the maximum sentence according to the prosecutor's demands, so that the defendant becomes deterrent and the community's sense of justice is fulfilled.
