Abstract
Mixing simulation between differences feedstock of aluminium scraps, formulation, combination and then melting process were examined to obtain ingot, which has quality similar to that of aluminium casting standard. The utilization of scrap as a feedstock can minimize environmental problem and also obtain benefit value for waste products. The standard ingot from aluminium alloy BS 1490-LM4 and LM13 have made using scraps feedstock, which derived from waste products. Aluminium scraps, which contained piston scrap, wire, plate, electrical arch, gear, and machine block, were obtained from small size industries of metal non-iron processing at Pasuruan, East Java. ln this study, scrap feedstock were separated according to their types. Then, their chemical composition were analysed using spectrometer. Computerize calculation for formulation and fusion were carried out before melting process. Additional matters of fusion were conducted as melting process occurs to obtain a target composition. Melting was carried out in the crucible muffle using cokes as fuels at temperature of 72O°C. Liquid metal product was poured onto sand and metal moulds. Afterwards, these product were tested in order to find their mechanic strength and stiffness. Nletalographic analyses on these products were also carried out using optical microscope. The making of ingot standard LM4 and LM13 were successfully obtained in fulfilling the standard composition. The mechanic strength and micro-structure of ingot, produced from metal mould, has shown good performance than that of produced from sand mould. This examination shown that the porosity affected mechanic strength. ingot sand mould, which has high porosity, gave less strength compared to that of ingot metal mould, which has small porosity. The casting methode using metal mould produced ingot with increasing in mechanic strength by 30% compared to that of methode using sand mould. It was also found that or (Al) and eutectic phases were formed from micro-structure of standard ingot, which shown similar to that phase diagram binary fusion AlSi. It was also evidence that ingot remelting caused reduction in silicon concentration by 30-40%

Sebagai negara maritim, Indonesia memiliki total keseluruhan kapal mencapai 63.000 kapal dengan 60 persen diantaranya berusia lebih dari 20 tahun, hal ini membuat besarnya potensi jumlah keberadaan kapal tua yang sudah tidak layak beroperasi dan harus di daur ulang. Selain itu, terlepas dari besarnya prospek pasar internasional green ship recycling yang terus meningkat khususnya berhubungan dengan European Union Ship Recycling Facility (EUSRF), Indonesia masih kalah bersaing di pasar internasional dalam industri green ship recycling, dibuktikan dengan adanya 23 kapal berbendera Indonesia dari 630 kapal komersial dan unit lepas pantai yang terjual untuk ditutuh di luar Indonesia menurut NGO Shipbreaking Platform 2020, serta ditambah masih terdapatnya kebutuhan baja dalam negeri yang terus meningkat. Hal tersebut terjadi karena kondisi industri green ship recycling Indonesia yang masih jauh dari kondisi ideal yang mendesak untuk diwujudkan menjelang akan berlakunya Hongkong Convention pada 26 Juni 2025. Kondisi Ship Recycling Facility di Indonesia masih banyak menggunakan metode beaching yang merusak lingkungan dan tidak memperhatikan aspek keselamatan, keamanan, dan kesehatan pekerja akibat dari minimnya pengaturan mengenai aspek teknis, prosedur, dan fasilitas. Maka dari itu dilakukan penelitian ini dengan tujuan menghasilkan strategi pengembangan Green Ship Recycling Facility sesuai keadaan di Indonesia serta memenuhi ketentuan internasional dan mencapai kepentingan ekonomis. Dalam penelitian ini dihasilkan rekomendasi kombinasi alternatif sistem dan teknologi yang optimal untuk digunakan di ship recycling facility melalui metode Analytical Network Process (ANP) dan in-depth interview terhadap stakeholders (praktisi, regulator, dan pakar) di industri ship recycling Indonesia dengan hasil yaitu: LPG/oxy-acetylene sebagai cutting technology, sandblasting sebagai decoating technology, landing/wet-basin sebagai docking system, mobile crane sebagai material handling technology, dan randomized storage system sebagai storage system. Lalu dilakukan pula kajian untuk menghasilkan rancangan prosedur dan tata letak area beserta fasilitas, rancangan pemilahan limbah per ketegori material berbahaya (HAZMAT), rancangan prosedur identifikasi material selama proses ship recycling, rancangan ketentuan fasilitas penanganan dan penyimpanan material berbahaya (HAZMAT), serta studi kasus pengembangan fasilitas yang dilakukan terhadap salah satu ship recycling facility semi modern di Cilegon, Indonesia, mencangkup gap analysis, rekomendasi pengembangan, dan design layout berdasarkan kajian rancangan yang telah dilakukan. ......As a maritime country, Indonesia has a total of 63,000 ships, with 60 percent of them being over 20 years old. This creates a significant potential for the existence of old ships that are no longer operational and need to be recycled. Additionally, despite the growing prospects of the international green ship recycling market, particularly in relation to the European Union Ship Recycling Facility (EUSRF), Indonesia still places behind in the international market in the green ship recycling industry. This is evidenced by 23 Indonesian-flagged ships out of 630 commercial ships and offshore units being sold for dismantling outside of Indonesia, according to the NGO Shipbreaking Platform 2020. Moreover, there is a continuous increase in domestic steel demand. This happened because the condition of the green ship recycling industry in Indonesia is still far from the ideal conditions that are urgently needed to be realized, especially with the upcoming implementation of Hong Kong Convention on 26 June 2025. Ship Recycling Facilities in Indonesia still extensively use beaching methods that damage the environment and disregard safety, security, and workers' health aspects, primarily due to the lack of regulations concerning technical aspects, procedures, and facilities. Hence, this research aims to develop a strategy for Green Ship Recycling Facility based on the Indonesia’s condition, while complying with international regulations and achieving economic interests. The study resulted in recommendations for an optimal combination of alternative systems and technologies to be used in ship recycling facilities, using the Analytical Network Process (ANP) method and in-depth interviews with stakeholders (practitioners, regulators, and experts) in the Indonesian ship recycling industry. The recommendations include LPG/oxy-acetylene as cutting technology, sandblasting as decoating technology, landing/wet-basin as the docking system, mobile crane as material handling technology, and randomized storage system as the storage system. Furthermore, the study also conducted an assessment to generate designs for procedures, layout areas, and facilities, waste categorization procedures for hazardous materials (HAZMAT), material identification procedures during the ship recycling process, requirements for handling and storing hazardous materials (HAZMAT), and a case study on the development of a facility in one of the semi-modern ship recycling facilities in Cilegon, Indonesia. This case study covers gap analysis, development recommendations, and design layout based on the conducted design assessment.

ABSTRAK Setiap tahun jumlah limbah organik padat selalu bertambah dengan pesat seiring dengan bertambahnya jumlah penduduk, peningkatan pendapatan, perkembangan industri dan kegiatan-kegiatan lainnya. Limbah organik tersebut beium bisa ditangani karena dari waktu ke waktu terus meningkat jumlahnya, sementara lahan tempat penampungannya semakin terbatas. Berbagai upaya untuk mengatasi menumpuknya limbah padat, cair dan gas serta cara penangananya masih terbatas. Penanganan limbah organik padat pada umumnya didasarkan pada tiga sistem yaitu pembuangan, pembakaran dan pengomposan. Dari ketiga cara tersebut, yang paling baik dan secara teknis memang sangat cocok untuk menangani limbah organik padat adalah melakukan daur ulang dengan cara pengomposan. Mendaur ulang sampah dengan cara pengomposan akan dapat mengurangi jumlah sampah di perkotaan, dengan demikian biaya pengangkutan pun akan berkurang. Dalam proses pembuatan kompos, cacing tanah juga dapat digunakan dalam membantu proses perombakan bahan-bahan organik. Sebagai akibat dari perombakan secara biologis yang dilakukan oleh cacing tanah dan mikroorganisme adalah dihasilkannya casting yang mempunyai kandungan unsur hara. Untuk mengetahui seberapa jauh peranan cacing tanah dalam proses dekomposisi bahan organik, maka dilakukan penelitian yang secara umum bertujuan untuk mengetahui karekteristik casting hasil pengomposan, dan secara spesifik bertujuan untuk mengetahui perbandingan antara limbah organik padat dari pasar (sisa sayuran) dengan limbah RPH (isi rumen) yang optimal agar proses pengomposan dengan menggunakan cacing tanah berjalan baik dan casting yang dihasilkan mengandung unsur hara yang tinggi. Bahan-bahan yang digunakan dalam percobaan adalah kombinasi antara limbah pasar (sisa sayuran) dengan limbah RPH (isi rumen) yang dibuat bervariasi dalam volumenya dalam 250 gram cacing tanah, yang terdiri dari: (1) PRi - perbandingan antara limbah pasar dengan limbah RPH 100 . 0 dalam 250 gram racing tanah. (2) PR2 = perbandingan antara limbah pasar dengan limbah RPH 75 : 25 dalam 250 gram cacing tanah. (3) PR3 = perbandingan antara limbah pasar dengan limbah RPH 50 : 50 dalam 250 gram cacing tanah, (4) PR4 perbandingan antara limbah pasar dengan limbah RPH 25 .: 75 dalam 250 gram cacing tanah dan (5) PR5 = perbandingan antara limbah pasar dengan limbah RPH 0 100 dalam 250 gram cacing tanah. Rancangan yang digunakan dalam percobaan adalah rancangan acak lengkap ORAL) yang diulang tiga kali. Limbah arganik padat dari pasar (sisa sayuran) dan limbah RPH (isi rumen) serta campuran antar keduanya dapat dirombak oleh cacing tanah menjadi casting. Limbah Organik padat yang telah berubah menjadi casting dicirikan oleh berubahnya limbah menjadi massa yang remah, berwarna caklat kehitaman, sulit dikenali lagi dari bahan asalnya dan terjadi perubahan sifat-sifat kimianya. Dilihat dari strukturnya, pada perlakuan PR1, PR2 dan PR3 casting yang diperoleh mempunyai struktur remah sedang pada perlakuan PR4 dan PR5 strukturnya padat. Sifat-sifat biologi limbah yang telah difermentasikan selama dua minggu tetapi belum diberi racing tanah menunjukkan bahwa jenis mikroorganisme yang terdapat pada limbah pasar terdapat juga pada limbah RPH, namun jumlah totalnya berbeda. Sedangkan hasil panen cacing tanah menunjukkan bahwa perlakuan percobaan memberikan pengaruh yang nyata, dan perlakuan yang memberikan bobot cacing tanah paling tinggi adalah pada perlakuan campuran antar limbah pasar dengan limbah RPH dengan perbandingan 50:50. Sifat-sifat kimia casting yang ditunjukkan oleh kandungan logam beratnya menunjukkan bahwa pada semua perlakuan menghasilkan casting yang mengandung logam berat sangat rendah, jauh di bawah standar lingkungan hidup yang diterapkan di Amerika Serikat (EPA Standard). Demikian juga terhadap kandungan unsur-unsur hara makro (N,P,K.) dan mikro (Fe, Mn, Al, Cu dan Zn) semua perlakuan memberikan pengaruh yang nyata terhadap semua variabel yang diamati, kecuali terhadap unsur nitrogen.

ABSTRACT Solid Organic Waste Utilization Into Casting Through CompostingEvery year the amount of solid organic waste always increase rapidly parallel with increased number of resident, income improvement, industrial development and other activities. Organic waste mentioned can not yet be handle because from time to time always rises its amount, while its receiver site land is more and more limited. Various attempt for overcoming accumulated solid waste, liquid and gaseous waste its handling manner is still limited. Solid organic waste its waste in general is based on three system i.e disposal, burning and composting. Whereas from the three manner mentioned, so the best one and technically is really very suitable for handling of solid organic waste namely making recycle by way of composting. Recycling waste by means of composting will be able to reduce the amount of waste in urban, thus its transport cost will also decrease. In the compost making process, earthworm can also be used in helping the organic matters 'process of decomposition. So the result of biological decomposition that is made by earthworm and microorganism namely produced casting which has nutrient element content. To identify what extent is the role of earthworm in the organic matter process of decomposition, then it is made a research which in general aims to know the characteristic of composting product casting, and specially aims to know the ratio between solid organic waste from market (vegetable remnant) to butcher's waste (rumen content) that is optimal so that process of fertilization by using the earthworm runs well and casting that is produced contains high nutrient element. Materials used in the experiment is the combination between market waste (vegetable remnant) with butcher's waste (rumen content) that is made various in its volume The biological properties of waste that has been fermented during two weeks but not yet given earthworm indicate that type of microorganism which occurs on the market waste occurs also in butcher's waste, yet its total number differs. While earthworm harvest indicates that trial treatment gives obvious effect, and treatment which gives the highest earthworm is in the mixed treatment between market waste and butcher's waste with ratio 50 : 50. The chemical properties of casting that is indicated by its heavy metal content indicate that in all treatment it produces casting that contain very low heavy metal, far under life environment standard that is practiced in the United States (EPA Standard). Similarly on the macro (N, P, K) and micro (Fe, Mn, Al, Cu and Zn) nutrient elements content all treatments give obvious effect to all variables observed, except to the nitrogen element. in 25 grams earthworm, which consists of : (1) PR1 = the ratio between market waste to butcher's waste 100 : 0 in 250 grams earthworm; (2) PR2 = ratio between market waste to butcher's waste 75 : 25 in 250 grams earthworm; (3) FR3 ratio between market waste to butcher's waste 50 : 50 in 250 grams earthworm; (4) PR4 = ratio between market waste to butcher's waste 25 : 75 in 250 grams earthworm and (5) PR5 = ratio between market waste to butcher's waste 0 : 100 in 250 grams earthworm. The design used in experiment is completely Randomized Design (CRD) that is repeated three times. Solid organic waste from market (vegetable remnant) and butcher's waste (rumen content) and the mixture between both can be decomposed by earthworm into casting. Solid organic waste that has changed into casting is characterized by changed waste into crumbed mass, blackish brown in color, hard to be known again from its original material and it occurs the change of its chemical properties. Observed from its structure, in the treatments PR1, PR2 and PR3 casting that is gain has moderate crumb structure and in the treatment PR4 and PR5 its structure is solid or compact.

End-of-life Vehicle (ELV) recovery is a promising strategy to minimize the environmental impact of automotives on environmental sustainability. This study aims to assess the community?s knowledge from a socio-technical perspective on ELV. A survey was conducted in Japan and Malaysia to assess public perception on ELV recovery. The results showed that the communities in both countries have basic knowledge and a reasonably good level of awareness on environmental issues and recovery strategies such as recycling. However, there is a high level of uncertainty on the concept of ELV reuse and remanufacturing, as more than 50% of respondents were unsure of their willingness to participate in ELV initiatives. The respondents agreed that the industry and government should take the necessary steps to support the reuse strategy. The paper concludes with suggestions from a socio-technical perspective, which aim to ensure an effective implementation of ELV recovery through reuse and remanufacturing.
