Abstract

ABSTRACT The increased activities in hospitals will increase the infectious waste generation. The infectious waste contains pathogenic organisms that can spread disease to humans and the environment. The harmful impact of infectious waste can be minimized through proper waste management, starting from waste generation. This study aims to examine the problem of infectious waste generation: the overall percentage of infectious waste generation in hospitals, the amount of infectious waste generation from each source (processing unit), and analyze factors that significantly affected its generation. This study is expected to be the basis of recommendations for hospitals in handling infectious waste. The study was conducted in four public hospitals in Bandung and Cimahi City. The data consists of infectious waste generation, non-infectious waste (general waste) generation, and hospital data as data factors analyzed for its influence on waste generation. The stepwise regression method was used for factor analysis with 95% CI. The result showed that infectious waste generation had a lower percentage than non-infectious waste, ranging from 38–47%. The treatment rooms that produce the most considerable infectious waste are haemodialysis, operating rooms and inpatients with an average infectious waste generation of 0,08–2,18 kg/patient/day. Thus, the three rooms can become a priority for infectious waste management. Factors that significantly affect the generation of infectious waste are dominated by patients and medical personnel. The importance of this factor is related to waste sorting activities. Therefore, special control by hospital management is needed for these two factors. Keywords: hospital, generation, infectious waste, treatment room, factors   ABSTRAK Peningkatan aktivitas rumah sakit akan diikuti dengan peningkatan timbulan limbah infeksius. Limbah infeksius mengandung organisme patogen yang dapat menyebarkan penyakit bagi manusia dan lingkungan. Dampak limbah infeksius dapat diminimalisir melalui kegiatan pengelolaan limbah yang tepat, dimulai dari timbulan limbah. Penelitian ini bertujuan mengkaji secara mendalam hal seputar timbulan limbah infeksius, dimulai dari persentase timbulan limbah infeksius rumah sakit secara keseluruhan, besaran timbulan limbah infeksius dari setiap sumber (unit perawatan) serta analisa terhadap faktor yang memiliki pengaruh signifikan terhadap timbulan limbah. Kajian ini diharapkan dapat menjadi dasar rekomendasi untuk pengelolaan limbah infeksius rumah sakit. Penelitian dilakukan di empat rumah sakit umum area Kota Bandung dan Cimahi. Data penelitian terdiri atas timbulan limbah infeksius dan non-infeksius (limbah umum) serta data atribut rumah sakit sebagai data faktor yang dianalisis pengaruhnya terhadap timbulan limbah. Analisis faktor menggunakan metode stepwise regression dengan signifikansi 0,05 (95% CI). Hasil penelitian menunjukkan limbah infeksius memiliki persentase timbulan yang lebih kecil dibandingkan limbah non-infeksius (limbah umum) yaitu kisaran 38–47%. Unit perawatan yang menjadi penghasil limbah infeksius terbesar berasal dari unit haemodialisa, kamar operasi serta rawat inap dengan kisaran rata-rata besaran timbulan limbah infeksius sebesar 0,08–2,18 kg/pasien/hari. Dengan demikian, ketiga unit perawatan tersebut dapat menjadi prioritas pengelolaan limbah infeksius. Adapun faktor yang berpengaruh signifikan terhadap timbulan limbah infeksius didominasi oleh faktor jumlah pasien dan jumlah staf medis. Signifikan faktor ini berkaitan dengan kegiatan pemilahan limbah sehingga perlu pengendalian khusus poleh pihak rumah sakit terhadap kedua faktor tersebut. Kata kunci: rumah sakit, timbulan, limbah infeksius, unit perawatan, faktor

Abstract

ABSTRACT Organic waste from food and beverage can be degraded by microbes. The sludge from food industries still contains nutrition such as carbohydrates, proteins, and fats. One attempt to process and utilize the sludge is to reuse it as the growth medium for Black Soldier Fly (BSF) maggot, which is known to have high nutritional value for fish or livestock feed. This research used ice cream industrial sludge as maggot feed. The problem of using the ice cream industrial sludge for maggot feed is the odour that pollutes the environment. Biosorption is a technique for deodorizing waste sludge using organic materials. This research was conducted to obtain the most effective ratio of biosorbents from fermented manure (PKN), compost (K), and calcium carbonate animal shells (Ca) to remove odours by reducing N-ammonia and sulfide in ice cream industrial sludge using biosorption techniques. The effect of biosorbent used for BSF (Black Soldier Fly) maggot feed on maggot growth was also observed. The most effective biosorbent composition in reducing odor, N-ammonia, and sulfide of the sludge was K:Ca:Sludge (1:1:3) with adsorption time of 48 hours and the percentage reduction of 85.0%. However, the number and size of maggot with PKN:K:Sludge (1:1:3) growth media were higher than K:Ca:Sludge (1:1:3). The ratio of PKN:K:Sludge (1:1:3) was proven to increase maggots' growth to provide benefits for farmers in increasing maggot production both in number and size. Keywords: Black Soldier Fly maggot, biosorbent, biosorption, organic waste, waste deodorization   ABSTRAK Limbah organik dari industri makanan dan minuman dapat didegradasi oleh mikroba. Sludge dari limbah industri makanan masih mengandung bahan-bahan nutrisi seperti karbohidrat, protein, dan lemak. Salah satu usaha untuk mengolah dan memanfaatkan sludge tersebut adalah dengan menggunakannya kembali sebagai media pertumbuhan maggot Black Soldier Fly (BSF) yang diketahui sangat tinggi kandungan nutrisinya untuk bahan pakan ikan atau ternak. Penelitian ini menggunakan limbah organik dari industri es krim sebagai pakan maggot. Masalah yang ditimbulkan dari pemanfaatan limbah sludge industri es krim untuk pakan maggot adalah bau yang mengganggu dan mencemari lingkungan. Biosorpsi merupakan salah satu cara untuk menghilangkan bau (deodorisasi) pada limbah sludge. Penelitian ini bertujuan untuk mendapatkan rasio biosorben pupuk kandang fermentasi (PKN), kompos (K) dan kalsium karbonat dari cangkang hewan (Ca) yang paling efektif dalam menghilangkan bau dengan menurunkan N-amonia dan sulfida pada limbah sludge industri es krim melalui teknik biosorpsi. Pengaruh biosorben yang digunakan untuk pakan maggot BSF juga diamati terhadap pertumbuhan maggot. Rasio K:Ca:Sludge (1:1:3) dengan waktu adsorpsi 48 jam merupakan rasio yang lebih efektif untuk menurunkan bau, N-amonia, dan sulfida pada sludge dengan presentase penurunan 85,0%. Akan tetapi, jumlah dan ukuran maggot hasil panen dengan media pertumbuhan PKN:K:Sludge (1:1:3) lebih besar dibandingkan dengan K:Ca:Sludge (1:1:3). Rasio PKN:K:Sludge (1:1:3) terbukti dapat meningkatkan pertumbuhan maggot sehingga memberi manfaat bagi peternak dalam meningkatkan produksi maggot baik secara jumlah dan ukurannya.

Abstract

ABSTRACT Biomass as raw material is one solution that can be developed in the management of agricultural, plantation, and industrial waste. The utilization of biomass-derived from waste can help reduce pollution and environmental pollution. This research was conducted to make Silicon Carbide (SiC) adsorbent from wood biomass using Sengon sawdust as a source of carbon and non-wood biomass, namely coconut husk, as a source of silica. SiC adsorbent is applied for ammonium adsorption, which has implications on reducing ammonia gas from wastewater, reducing odor. The research methods included isolation of silica and carbon, the production of SiC adsorbent by magnesiothermic reduction, and the characterization of SiC adsorbents with XRD and SEM-EDX. Adsorption capacities of SiC to ammonium were determined according to SiO2:C adsorbent ratios (1:3 and 5:3), adsorbent mass variations, and ammonium concentrations in simulated wastewater using the spectrophotometric method. The results showed that SiC could be used as an adsorbent because there are pores on the surface structure. The optimum SiO2:C adsorbent ratio in adsorbing ammonium was 1:3 (SiC 136) with 45% adsorbed ammonium and an adsorption capacity of 0.47 mg/g. The optimum adsorbent mass in adsorbing ammonium was 0.1 g with 41.77% adsorbed ammonium. The optimum concentration of ammonium in simulated wastewater for ammonium adsorption was 20 mg/L with 46.25% adsorbed ammonium. The adsorption isotherm pattern during the ammonium adsorption process follows the Freundlich isotherm, which means that the adsorption process occurs physically. Keywords: adsorbent, adsorption, ammonia, biomass, coconut husk, SiC   ABSTRAK Biomassa sebagai raw material merupakan salah satu solusi yang dapat dikembangkan dalam pengelolaan limbah hasil pertanian, perkebunan, dan industri. Pemanfaatan biomassa yang berasal dari limbah dapat membantu mengurangi tingkat polusi dan pencemaran lingkungan. Penelitian ini dilakukan untuk membuat adsorben Silikon Carbida (SiC) dari biomassa kayu yaitu memanfaatkan serbuk gergaji kayu Sengon sebagai sumber karbon dan biomassa non kayu yaitu sabut kelapa sebagai sumber silika. Adsorben SiC diaplikasikan dalam penjerapan amonium yang berimplikasi pada potensi penurunan gas amonia dari air limbah sehingga adsorben SiC berpotensi mengurangi bau dalam air limbah. Metode penelitian meliputi isolasi silika, isolasi karbon, pembuatan adsorben SiC secara reduksi magnesiotermik dan karakterisasi adsorben SiC dengan XRD dan SEM-EDX. Penentuan daya adsorpsi SiC sebagai adsorben terhadap variasi rasio adsorben SiO2:C (1:3 dan 5:3), variasi massa adsorben, variasi konsentrasi limbah simulasi menggunakan metode spektrofotometri. Hasil penelitian menunjukkan bahwa SiC dapat digunakan sebagai adsorben karena terdapat pori-pori pada struktur permukaan. Variasi rasio adsorben SiO2:C optimum dalam mengadsorpsi amonium ialah SiC 136 dengan amonium teradsorpsi sebanyak 45% dan kapasitas adsorpsi sebesar 0,47 mg/g. Massa adsorben optimum dalam mengadsorpsi amonium ialah 0,1 g dengan amonium teradsorpsi 41,77%. Konsentrasi optimum limbah simulasi dalam adsorpsi amonium 20 mg/L dengan amonium teradsorpsi 46,25%. Pola isoterm adsorpsi selama proses adsorpsi amonium mengikuti isoterm Freundlich, yang berarti proses adsorpsi cenderung terjadi secara fisika.
