Abstract

Organic fertilizer is a fertilizer that is expected to improve the physical, chemical, and biological properties of the agricultural land resources, which is undergoing fertilityand productivity degradation. Compost is one of the organic fertilizers produced from the biological decomposition process by a consortium of microorganisms, includingfunctional microorganisms. To make it easier for farmers and efficiency in the use of organic fertilizer, organic fertilizer will be further processed into granular form and is called Granules Organic Fertilizer (POG). In the manufacturing process, namely at the time of drying using a rotary dryer, was suspected of using high temperatures to kill microbes (including functional microbial) that naturally exist in the organic compost fertilizer (POK), which is the raw material for POG. To increase the presence of functional microbial populations, the POG which has produced before, then added with bio fertilizer that is rich in microbial functional. This research was conducted to determine and evaluate the total microbial population and functional microbial in pure POK, compared with the total microbial population and functional microbial in the POG are enriched with bio-fertilizer. The results showed: There is an indication to the higher number of total microbial population in the POK, who showed by total fungi population, compared with the POG. The number of functional microbial population, as shown by bacterial phosphate solvent and non-symbiotic bacteria that are fastening N in POK, very high and already meets the criteria to be called as a biological fertilizer. The amount is not significantly different compared to the POG that is already enriched with bio fertilizer that is rich in microbial functional. There is an indication of the influence of high heating using a rotary dryer, in the POG manufacturing process against the decreasing of the amount of microbialpopulation that are resulting in the POG, including functional microbial

Abstract

ABSTRACTLandfills contain materials that can be recovered to be recycled or used as an energy source. The purpose of this study is to conduct waste characterization that has long been buried in landfill which includes analysis of composition, proximate analysis, and ultimate analysis. Then the waste is analyzed for its use as recycled material and energy sources. The study was conducted at the Sukawinatan landfill (Palembang) and the Bantargebang landfill (Bekasi). Sampling was carried out on garbage that had been buried in landfills by digging at depths of up to 5 m using an excavator. Furthermore, the samples are dried in the sun, sifted with rotary screen, and sorted manually. Some samples were taken by quartering to be analyzed in the laboratory. The results of the research and analysis showed that (i) landfill waste was dominated by compost material (31-47%) and plastic combustible material (32-43%) and nonplastic combustible material (32-43%); (ii) shaped material such as compost has the potential as a substitute for landfill cover and as soil conditioner; (iii) potentially recycled materials such as plastic waste need intensive sorting and cleaning; (iv) landfills excavated waste can be potentially used as an energy source or refuse-derifed fuels (RDF) with a heating value between 7.31-15.61 MJ / kg; (v) landfills excavated waste has the potential to be used as fuel for incinerators; (vi) utilization of landfill waste for the cement industry still faces several obstacles such as high chlorine content and water content.Keywords: landfill, waste characterization, composition, proximate, ultimate ABSTRAKTPA mengandung material yang dapat diambil untuk didaur ulang atau dimanfaatkan sebagai sumber energi.

Abstract

Proses pembakaran sampah kota melalui insinerator akan menghasilkan uap panas yang bisa dimanfaatkan  untuk membangkitkan energi listrik, akan tetapi pada proses ini juga menghasilkan output berupa flue gas yang didominasi oleh partikel (fly ash) dan gas beracun seperti: HCl, SO2, NOx, HF, Hg, Cd dan Dioxin. Sebelum dibuang ke udara bebas, flue gas tersebut harus diolah agar memenuhi baku mutu lingkungan. Teknologi penanganan partikel dan gas polutan tersedia dan dapat dibuat dengan berbagai kapasitas. Untuk menangani flue gas dari insinerator sampah digunakan Quencher untuk menekan laju pembentukan kembali dioksin dan furan setelah proses pembakaran,  Spray Drying Absorption (SDA) untuk mengikat gas asam dan  logam berat serta bag filter untuk menangkap partikel. Selain itu digunakan ID Fan dan Cerobong Asap untuk pengatasi pressure drop yang terjadi akibat pengoperasian peralatan APC dan melepas ke udara.

Abstract

The number of scientific publications produced by Indonesian Collaborating Partners is still not optimal. When comparing the number of international research partnerships with the indicator of the number of Research Permits issued, the overall performance of international scientific publications resulted by Indonesian Partners, especially joint publications (co-authorship) Indonesian researchers and foreign researchers, is still very low. This study examines the research management undertaken by Indonesian partner institutions in international collaborative research and its positive impact on scientific publication performance. The research adopts a qualitative approach. Primary data were collected through structured in-depth interviews with 31 key informen selected using purposive method. Risk management analysis has been applied as theoretical framework to explain the implementation of research partnership carried out by Indonesian partner institutions in international research collaboration. The performance of scientific publications is more an achievement of strengthening management undertaken by Indonesian partner institutions formulated into mutually agreed clauses in collaborative research agreements with foreign institutions, rather than being the outcome of foreign research permit policy.

Abstract

Pengelolaan sampah organik merupakan tantangan utama di Kabupaten Sukoharjo akibat tingginya volume sampah rumah tangga yang terus meningkat setiap tahun dan berkontribusi terhadap penumpukan di Tempat Pembuangan Akhir (TPA). Tanpa pengelolaan yang baik, sampah organik dapat menyebabkan berbagai permasalahan lingkungan. Program pengabdian masyarakat ini bertujuan untuk memberdayakan masyarakat melalui penerapan teknologi pengelolaan sampah organik guna mengurangi beban lingkungan dan menciptakan nilai ekonomi. Kegiatan yang dilakukan meliputi sosialisasi, pelatihan, serta implementasi teknologi seperti komposter aerobik, lubang resapan biopori, dan eco-enzyme. Pelatihan ini membekali mitra bank sampah dan masyarakat dengan keterampilan praktis dalam mengelola sampah organik menjadi produk yang bernilai ekonomi dan ramah lingkungan. Hasil program menunjukkan peningkatan kapasitas masyarakat dalam pengelolaan sampah organik, dengan 90% peserta berhasil mengadopsi teknologi yang diajarkan. Kendala utama yang dihadapi adalah kurangnya pemahaman awal dan keterbatasan infrastruktur pendukung, namun faktor pendorong seperti kesadaran masyarakat yang tinggi serta dukungan pemerintah daerah berperan dalam keberhasilan program. Program ini tidak hanya mengurangi volume sampah organik secara signifikan, tetapi juga membuka peluang ekonomi melalui pemanfaatan limbah. Selain itu, keberlanjutan program dapat diperkuat dengan kolaborasi antara komunitas, akademisi, dan pemerintah untuk meningkatkan efektivitas pengelolaan sampah. Keberhasilan model ini diharapkan dapat diterapkan di daerah lain yang menghadapi permasalahan serupa guna mewujudkan sistem pengelolaan sampah yang lebih berkelanjutan.
