Abstract

The generation of municipal solid waste (MSW) in Bali has various environmental impacts. One of the updates on sustainable waste processing is the RDF treatment plant processing. Before carrying out the processing, MSW characterization is needed because each region has a diverse composition. The processing of MSW into RDF provides benefits for achieving MSW reduction targets, renewable energy use, and the reduction of greenhouse gas (GHG) emissions. For this reason, this study was conducted to determine the potential of MSW in Bali as an alternative to renewable fuel and its potential to reduce GHG. MSW's potential calorific value as a raw material for RDF in Bali can reach 9.58 - 17.71 MJ/kg. The implementation of processing waste into RDF in pellets has shown a calorific value of ± 3904 - 4945 kkcal/kg. Implementing MSW processing into RDF in Bali can reduce GHG by 178 - 330 times compared to open dumping.

Abstract

Kegiatan upacara di tempat suci pura di Pulau Bali rata-rata menghasilkan sampah sekitar 2000 L/hari. Sebagai bagian yang sangat penting dari budaya Bali, sesajen yang terdiri dari bunga, daun, buah-buahan dan bambu disajikan di setiap upacara keagamaan. Pembuangan sampah pura yang tidak tepat berpotensi menimbulkan gangguan pada kehidupan manusia dan lingkungan, seperti air dan sanitasi, penumpukan sampah, peningkatan tingkat pencemaran, dan kesehatan manusia. Penelitian ini bertujuan untuk mendaur ulang sampah pura, khususnya sisa bunga menjadi dupa organik serta mengkaji alternatif lain dalam daur ulang sampah pura. Daur ulang sisa bunga menjadi dupa organik dilakukan dengan menggunakan tiga bahan campuran. Kajian literatur digunakan untuk menambah informasi alternatif daur ulang sampah pura dari penelitian sebelumnya. Hasil eksperimen menunjukan bahwa sampah sisa bunga dapat didaur ulang menjadi dupa organik. Rasio campuran 1:2 untuk sisa bunga dan bubuk esensial memberikan hasil terbaik. Dupa organik yang terbentuk sangat kuat dan padat. Selain itu, aroma campuran yang dihasilkan lebih baik di antara yang lain. Sampah pura juga dapat didaur ulang menjadi beberapa produk berharga, seperti kompos, ekstrak warna minyak atsiri, bubuk warna, atau biogas. Diestimasikan sebuah pura menghasilkan sekitar 200 kilogram sampah pura dalam satu hari upacara. Sekitar 40% dari sampah pura merupakan sisa bunga (berat basah) dengan kadar air sekitar 80%. Setelah melalui proses pengeringan, sisa bunga mencapai 16 kilogram. Diperkirakan sekitar 45 ton sampah pura dari 230 pura publik di Pulau Bali dapat didaur ulang setiap tahun melalui upaya daur ulang. Beberapa dampak yang ditimbulkan dari upaya daur ulang ini, seperti mengurangi sampah pura, menciptakan produk daur ulang yang dapat dipasarkan, dan meningkatkan keharmonisan antara budaya, lingkungan, dan masyarakat melalui pemberdayaan masyarakat. ABSTRACTCeremonial’s activities in Bali’s Temple have produced about 2000 L/day of waste in average. As an integral part of Balinese culture, devotion offerings which consists of flowers, leaves, fruits and bamboo are presented at every ceremony. The improper disposal of temple waste potentially causes a stress on the basic services in human life, such as water and sanitation, waste accumulation, raising the level of pollution, and human health. The present study aims to leverage of temple waste, especially discarded flower into organic incense through recycling and find out the foreseen impact of this initiative to the environment. Processing discarded flower into organic incense was conducted in this research with three material mixtures ratio. A literature review was added to enhance the alternatives of discarded flowers recycling on previous research. It is found that discarded flower was successfully recycled into organic incense. The preliminary experiments showed that the ratio of 1:2 for discarded flowers and essential powder gave the best results. The incenses were very strong formed and solid. Additionally, the smell of best mixture was the best among others. Besides, temple waste can be recycled to some valuable products, such as vermicompost, dyes extraction, essential oil, color powder, or biogas. It assumed that a temple has produced around 200 kilograms of temple waste during a ceremonial day. About 40% of those was discarded flowers (wet weight) that 80% contains water. After the drying process, it has left 16 kilograms of dried discarded flowers. It estimated around 45 tons of discarded flowers from 230 public temples around Bali could be recycled every year through this recycling effort. Some impacts come up with following this initiative, such as reducing the temple waste, creating a marketable recycling product, and build up a harmony between the cultural, environment, and society through community empowerment.

Abstract

The generation of organic waste is one of the biggest problems in developing countries like Indonesia. Examples of organic waste that can be obtained, such as leaves, include banana leaves and coconut leaves. One way to process waste that can generally be done is by composting. In the composting process, a bioactivator such as EM4 is needed to accelerate the reaction process in the waste. This study aimed to determine the effectiveness of EM4 bioactivator in the degradation process of banana leaf and coconut leaf waste. Measurement of processing quality is measured in-situ with parameters of temperature, pH, and humidity. The waste temperature increased above 32oC for the addition of EM4 bioactivator, while without the addition of bioactivator it only increased to 31oC. pH tended to be in normal conditions and was in an acidic state on day 12. Humidity decreased from the beginning of the waste process to the end of the process. The final result of composting quality has met the criteria of SNI 19-7030-2004. There was also a decrease in the C/N content during the process, adjusting to soil conditions. The decrease in the value of C/N on the addition of bioactivator also influences the composting process.

Abstract

Tourism Awareness Groups (Pokdarwis) have been established in each and every village in the Kerambitan District as part of the government's ongoing effort to promote village tourism. The economic potential of the village's natural resources is underutilized because the Pokdarwis party does a poor job of managing and capitalizing on tourism opportunities to tap into these resources. Each of the Kerambitan District's villages features a Tourist Destination of Interest (DTW), which represents a golden opportunity to earn from tourism by creating and selling a customized tour package. Kerambitan District's DTW is mostly made up of natural tourism possibilities, such as rice fields and beaches. Kerambitan District's attractions rely only on entrance fees from tourists for revenue, hence there are no tour packages available at this time. The objective is that this package would encourage more people to visit Kerambitan District and enjoy its many attractions. SIGADis, a web-based tool, is used to aid partners in the Kerambitan District with promotions, reservations, and ticket sales. To develop an integrated system in the Kerambitan District, this SIGADis app provides details on DTW in the form of narratives and visuals, as well as tour packages, ancillary services, lodging options, and geographic coordinates. Partners receive support and training as they learn to use the SIGADis application. The effectiveness of the SIGADis application training was evaluated by administering surveys to course participants, with scores averaging between 80% and 90%. These results indicate that individuals now comprehend how to utilize the SIGADis application better than previously

Abstract

ABSTRAKSampah bunga merupakan salah satu sampah yang secara spesifik dihasilkan dari kegiatan seremoni agama Hindu. Sampah ini dapat dimanfaatkan sebagai kompos karena mengandung bahan organik yang mudah didegradasi. Untuk mempercepat proses degradasi dibutuhkan bioaktivator. Tujuan dari studi ini adalah untuk mengetahui pengaruh pemberian biaktivator berbeda terhadap proses pembuatan kompos sampah bunga. Sampel sampah bunga yang digunakan terdiri dari gemitir (Tagates erecta L.), pacar air (Impatiens balsamina L.), bunga hortensia (Hydrangea), dan kamboja (Plumeria). Reaktor yang digunakan dalam penelitian ini adalah dengan reaktor aerobik yang dilengkapi dengan lubang untuk sirkulasi udara. Suhu dan pH dalam reaktor komposting mengalami perubahan dari 25-26oC ke suhu sekitar 35-36oC sedangkan pH menjadi ke pH normal. Hal ini menunjukkan adanya proses metabolisme dalam reaktor. Kada air alam sampah mengalami penurunan dari sekitar 80% menjadi dibawah 50% selama waktu detensi 30 hari. C/N hasil pengolahan memiliki nilai signifikansi 0.504, dengan nilai 14.3-15.8. Hal ini menunjukkan pemberian bioaktivator yang berbeda tidak mempengaruhi (F-value: 0.867 dan P-value: 0.504) proses pengolahan sampah bunga menjadi kompos.Kata kunci: bioaktivator, C/N, kompos, sampah bungaABSTRACTFlower waste is one of the waste that is specifically produced from Hindu religious ceremonies. This waste can be used as compost because it contains organic matter that is easily degraded. To encourage the bioactivator degradation process is needed. The purpose of this study was to determine the effect of giving different activators to the composting process of flower waste. The flower waste samples used consisted of gemitir (Tagates erecta L.), water henna (Impatiens balsamina L.), hydrangea (Hydrangea), and frangipani (Plumeria). The reactor used in this study is a reactor equipped with holes for air circulation. The temperature and pH in the composting reactor changed from 25-26oC to a temperature of around 35-36oC while the pH became normal. This indicates the presence of a metabolic process in the reactor. The water content in the waste decreased from about 80% to below 50% during the 30-day detention period. C/N processing results have a significance value of 0.504, with a value of 14.3-15.8. This shows that the application of different bioactivators does not affect (F-value: 0.867 and P-value: 0.504) the processing of flower waste into compost.Keywords: bioactivator, C/N, compost, flower waste

Abstract

Bali island as one of the best tourism destinations in the world is producing waste around 4.281 ton/day, including the temple waste. Every month, over 3 million Balinese Hindus carry out ceremonies. At the end of the day, each temple produces about 2000 L of temple waste, which is directly disposed to landfill without any treatment due to the insufficiency of waste processing facilities. The treatment of temple waste potentially such as water sanitation, waste accumulation, pollution, and human health. This study describes the characteristic of temple waste generated from home and the efforts of temple waste recycling initiatives. The temple waste is generally composed by 80% of organic material, such as flowers, leaves, fruit and food waste, coconut, bamboo, and in other side the plastic does exist. Some initiatives in recycling the temple waste were done in the previous research, such as aromatherapeutic incense from discarded flowers, generating vermicompost by mixing the discarded flowers with cow dung, and producing biofuel from marigold flowers. A recycling improvement is urgently needed by the existing temple waste in Bali. It is expected that Balinese Temple as the cultural icon of Bali would not be longer become the waste contributor to the landfill.

Abstract

Domestic wastewater effluent is the main contributor to diverse water pollution problems. The contaminants contained in the wastewater lead the low quality of water. The presence of ammonium and nitrate along with phosphorus are potentially cause eutrophication and endanger aquatic life. It increases the growth rate of algae and pressing down the dissolved oxygen which is highly corresponding to the death of aquatic animal due to anaerobic condition. Excess nutrients, mostly N and P is main cause of eutrophication which is result in oxygen depletion, biodiversity reduction, fish kills, odor and increased toxicityAn advance biological nitrogen removal process called anammox is a sustainable and cost effective alternative to the basic method of nitrogen removal, such as nitrification and denitrification. Many research have been conducted through anammox and resulted promisingly way to remove nitrogen. In this process, ammonium will be oxidized with nitrite as electron acceptor to produce nitrogen gas and low nitrate in anoxic condition. Anammox requires less oxygen demand, no needs external carbon source and low operational cost. Based on its advantages, anammox is possible to apply in domestic wastewater treatment with many further studies.
