Abstract

Secara umum pengunaan pestisida mempunyai dampak positif dam juga negatif. Dampak positifnya yaitu bebas dari hama pengganggu tanaman dan dampak negatifnya yaitu pestisida yang disemprotkan tidak semua terkena permukaan tanaman, namun 80% pestisida yang disemprotkan jatuh ke tanah .Salah satu dampak negatifnya adalah pencemaran lingkungan. Selain itu juga berdampak bagi kesehatan petani, konsumen, dan mikroorganisme yang tidak bisa pilih dan mencemari lingkungan khuusunya pada tanah dan air. Residu pestisida tersebut bisa mematikan makro dan mikro organisme dan juga keseimbangan alam dalam lingkungan. Pada produk pertanian residu pestisida juga mengganggu kesehatan, seperti melemahnya sistem imun, gangguan fungsi hati dan ginjal, kanker, dan gangguan kesehatan lainnya. Banyak jenis persitida yang digunakan petani, dan dalam pengapliaksian pestisida tersebut petani tidak menggunakan pelindung tangan yang berdampak pada kesehatan Penggunaan pestisida kimia yang berlebihan sehingga memiliki efek negatif, maka dari itu perlu ada nya pengenalan tentang pemanfaatan daun pepaya senagai bahan dasar pestisida nabati yang ramah lingkungan serta mudah didapat. Animo masyarakat saat ini masih sangat kurang karena proses pengolahan yang dianggap petani harus dilakuan berulang maka perlu inovasi pestisida nabati yang multifungsi. Selain fungsinya sebagai pengendali OPT (organisme pengganggu tanaman) serta kesuburan tanah sehingga dengan memberikan contoh pengaplikasian teknologi pada masyarakat yang berupa demfarm akan sangat menunjang implementasi pestisida nabati di masyarakat.

Parwiyanti, P., Yulistika, E., Rosidah, U., Lidiasari, E., & Syafutri, M. I. (2023). Estimation shelf life of microwavable fish crackers using the arrhenius reaction kinetics equation. In: Herlinda, S. et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 110-117).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Microwavable fish crackers had hygroscopic properties so it needs to be packaged properly. The objective of this research was to determine the shelf life of microwavable-packaged fish crackers. The fish crackers microwave was packed with three various method which are polypropylene (PP), PP + silica gel, and nylon + vacuum. Estimation of shelf life was done by calculating the parameters of degradation of microwavable fish crackers with the reaction kinetics equation and processed using the Arrhenius equation. The quality parameter was moisture content. Quality parameters are measured every 5 days during 30 days of storage at 30oC. The results showed that the kinetics of changes in the water content of microwavable fish crackers packed in three packaging combinations following reaction order one(1) and order two(2). The shelf life of microwavable fish crackers packaged in PP was 27 days, PP+silica gel packs was 29 days, and nylon+vacuum packs was 31 days.

Abstract

Managing end-of-life tyres (ELTs) has become an urgent global issue because tyres are difficult to decompose naturally and take more than 50 years to break down. In the Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) area, ELT generation is estimated at 2.5–3 million units annually, with the most significant contributions from Karawang (1,000 units per month) and Bogor (820 units per month). Bias-ply used tires, which contain up to 70% rubber, have significant potential for recycling into raw materials for new tires through reclaimed rubber technology, aligning with the principles of a circular economy. This study aims to map the supply chain ecosystem of ELTs, identify key stakeholders, and optimise material flow to support the development of the rubber industry from reclaimed materials. The study employs a qualitative descriptive method. The number of research locations was determined using the Solvin method with an error rate of 25%. Observations were performed at 15 specific tire shops, two truck tire shops, three fleets, and three used tire collectors in the Jabodetabek and West Java areas. The findings indicate that the total estimated number of ELTs collected in Jabodetabek from tire stores, truck tires, fleets, and collectors reaches 2,860 monthly units. The main challenges in ELT management include limited storage facilities, low awareness of the economic value of waste, and a predominantly conventional management system. The study also reveals that only 20% of ELTs are utilised optimally, highlighting a significant untapped potential.  Keywords: used tires, reclaimed rubber, supply chain, circular economy

Abstract

Klasifikasi kualitas hasil pengolahan limbah cair tahu sangat dibutuhkan untuk memudahkan proses pemantauan pengolahan limbah cair tahu. Tujuan penelitian ini adalah untuk menganalisis komponen dan pemodelan sistem guna membantu pengambilan keputusan akhir dari limbah cair tahu yang telah diolah dengan pendekatan Model Base System Engineering (MBSE) serta mengembangkan desain sistem klasifikasi untuk standar kualitas akhir limbah industri tahu menggunakan algoritma Decision Tree–ID3. Hasil penelitian menunjukkan bahwa proses pengolahan limbah cair yang diterapkan pada penelitian ini terdiri dari empat tahapan utama, yaitu pre-treatment, proses anaerobik, proses aerobik, dan proses kontrol (biotope pond). Pada proses kontrol di kolam biotop akan dipasang sensor untuk mengukur atribut BOD, COD, TSS, dan pH. Data sensor ini akan digunakan untuk membuat keputusan berdasarkan standar kualitas limbah industri, guna menentukan apakah hasil pengolahan limbah sudah "layak" untuk dibuang ke lingkungan atau "tidak layak" sehingga perlu diproses ulang di kolam anaerobik. Berdasarkan pemodelan dengan metode klasifikasi Decision Tree-ID3, atribut yang paling berpengaruh adalah COD dengan nilai (<301), diikuti oleh BOD dengan nilai (<150), kemudian decision pH dengan nilai (≥5,5), dan TSS dengan nilai (<100). Nilai variabel penting masing-masing adalah atribut COD sebesar 27,11, atribut BOD sebesar 19,17, atribut pH sebesar 16,12, dan atribut TSS sebesar 9,32. Hasil perhitungan dalam penelitian ini menunjukkan nilai akurasi sebesar 90%, presisi 87%, sensitivitas/recall 100%, dan spesifisitas 67%, dengan predikat klasifikasi yang sangat baik.

Abstract

Tofu is one of the products produced mainly by small and medium industries (SMEs). Along with the production of tofu by SMEs, there are many environmental problems. The industry's main ecological problems are waste management, efficient use of materials, water, and energy, and emissions generated during production. One solution that can be done to solve these problems is through the application of the circular economy concept. This research aimed to characterize the tofu production process, identify problems and analyze the potential application of the circular economy concept for the sustainable development of the tofu industry. The research was conducted through field observation and literature study. The research data were processed, analyzed, and presented in a qualitative descriptive manner. The results of the study show that the circular economy concept that can be adopted in the tofu industry A, B, and C is the utilization of solid waste in the form of tofu dregs as food ingredients (nuggets, tempe gembus, shredded and soy sauce), semi-finished foodstuffs (in the form of dregs flour which can be used as raw material for food processing such as crackers, pastries, and brownies), and as animal feed. Circular economy alternatives are analyzed by considering economic, environmental and social feasibility. Alternatives that are feasible and applicable to the tofu industry A, B, and C are washing soybeans in stages to reduce water use, tofu dregs are processed into tempe gembus or other products, cooking soybean porridge with boiler heating and cooking with a steam system, and liquid waste (whey) can be utilized as raw material for nata de soya, biogas and liquid fertilizer. Keywords: circular economy, tofu industry, sustainability
