Abstract

Pemuda adalah penggerak perubahan sosial. Artikel ini akan menganalisis hasil pengabdian masyarakat yang dilakukan ke pemuda untuk mempromosikan daur ulang sampah rumah tangga. Daur ulang sampah makanan menjadi fokus dalam kegiatan pengabdian kepada masyarakat ini karena banyak masyarakat yang masih belum sadar bahwa sampah makanan juga sangat penting untuk diperhatikan. Tiga topik utama yang akan diberikan dalam pengabdian masyarakat ini adalah daur ulang sampah makanan dengan composting, mengolah sampah makanan menjadi makanan binatang, menggunakan sisa bahan makanan untuk mengolah kembali menjadi kue. Topik-topik tersebut disampaikan ke pemuda untuk meningkatkan pengetahuan pemuda akan daur ulang sampah rumah tangga. Hasil dari pengabdian kepada masyarakat ini sesuai dengan tujuan dari kegiatan pengabdian masyarakat, yaitu meingkatkan pengetahuan pemuda akan daur ulang sampah sehingga dapat merangsang keinginan pemuda untuk memulai gerakan daur ulang sampah di masyarakat. Mereka juga punya keinginan untuk menyampaikan kembali materi daur ulang sampah yang disampaikan dalam program pengabdian kepada masyarakat ke pada masyarakat di sekitar mereka tinggal. Akan tetapi, kenaikan pengetahuan mereka tidak menaikkan keoptimisan mereka dalam melakukan daur ulang sampah. Beberapa di antara mereka masih skeptis pada kegiatan daur ulang sampah makanan akan berhasil diterapkan di masyarakat.

Abstract

INCREASING COMMUNTY INVOLVEMENT AND ECONOMIC VALUE OF HOUSEHOLD AND MARKET SOLID WASTE THROUGH CULTIVATING BLACK SOLDIER FLY MAGGOTS. The Klaten Regency area has at least more than 80 traditional markets owned by villages and local governments spread across a number of locations. Every market produces organic waste. About 60% of waste is generated from traders and 40% from residents around the market. Besides that, the community also produces large amounts of household solid waste. This service activity aims to increase the economic value of waste and the involvement of the community in Gempol Village, Karanganom District, Klaten Regency through the cultivation of black soldier fly (BSF). The service method starts with team formation, formulation of goals and outcome, identification of stakeholders, data collection and needs analysis, determination of priority problem solutions, preparation, implementation, mentoring, review and evaluation, determining new needs and targets. The result shows that Gempol village is ideal when managing household and market waste through BSF maggot cultivation. Through BSF maggot cultivation, household and markets solid waste are able to add economic value in a period of 7 days to 15 days. Dry maggot has a high selling value ranging between Rp. 95.000 / kg. Maggot derivative products such as fish feed, poultry feed, fishing bait range from Rp. 325.000/kg. The first outcome from this service activity was the enthusiasm of the community to be involved in managing household and market solid waste. The second outcome was stakeholder involvement, in this case the Environment and Forestry Service (DLHK) of Klaten Regency. The third outcome is opportunities for cooperation between participants (especially farmer groups) and universities. Participants hope that there will be sustainable activities, mentoring, and collaboration with other parties.

Abstract

Water is the main need for humans, so the quality and quantity must be maintained. The purpose of this research is to analyze the problems in Joho Village in the form of cloudy water so that the community feels disturbed. In this study, the water quality test was carried out using the Indonesian National Standard and with a random sampling technique. Samples were taken from 3 points in residents' houses and 2 points in public facilities, namely in parks and places of worship. Data analysis was carried out by descriptive quantitative. There is one sample that does not meet the quality standard for odor parameters, namely at the observation point in the park. However, for the turbidity parameter, all samples showed that none met the quality standards, namely 116, 48, 100, 136, 130 NTU. The solution that can be done by residents of Joho Village is to do pavement and closure in the area around the shallow well and perform simple filtration consisting of Zeolite (10 - 30 mm), Zeolite (5 - 10 mm), Silica sand (4 - 30 mesh), Activated Carbon, and Sponge.

Abstract

In the era of the COVID-19 Pandemic, medical waste is increasing in various hospitals, including UNS Hospital. The variables studied in the hazardous and toxic solid medical waste flow treatment. Primary data was obtained from an analysis of waste amount in 2021 and interviews with incinerator managers. Secondary data in the form of waste types, impacts, and incinerator residue were obtained from the literature study. This research aims to identify solid medical waste management with hazardous and toxic materials compared with Regulation of Environment and Forestry Minister of Republic Indonesia 56/2015. After analysis, it was found that there is dangerous and harmful solid medical waste flow management, distinguished by type. Particular colored medical waste is managed by reducing, sorting, storing, transporting, and destroying. Destruction is conducted with an incinerator. Arah Environmental Indonesia Company operates infectious medical waste. The potential impact of that waste can attack health, damage the environment quality, increase the degradation that has occurred, and pose a threat to microplastic. Completing waste management is done by tightening hospital regulations to produce output according to quality standards, limiting hazardous and toxic waste use, and selecting the waste.

Abstract

Eutrophication is a natural phenomenon in aquatic ecosystems that causes algae and other aquatic plants to overproduce. This process can benefit the ecology in tiny amounts, but too many nutrients can generate hazardous algal blooms and kill fish and other aquatic life. To prevent eutrophication and sustain aquatic ecosystems, agricultural waste water like microalgae production wastewater must be treated. The goal of the project is to get nitrogen and phosphorus out of the wastewater from growing microalgae, which is an agricultural waste water. One way to recover nutrients from wastewater is electrocoagulation. This procedure uses an electric current to create microscopic gas bubbles that collect and remove pollutants from wastewater. According to this study, electrocoagulation reduces phosphate and nitrate in microalgae culture wastewater. Phosphate concentration dropped by 90.20% in the 15th minute, while nitrate concentration dropped by 36.19% in the 30th minute. These reductions may be caused by struvite formation and nitrate conversion to nitrogen gas. This study demonstrates that electrocoagulation is a potential technology for recovering nutrients from agricultural waste water and reducing aquatic ecosystem eutrophication.

Abstract

Entikong Lama is a densely populated residential area and the center of economic activity located on the riverbank. However, there was poor management of municipal wastewater that influences water quality of the river. Moreover, the river water is used by society for drinking, cooking, bathing, washing and toileting. Hence, municipal wastewater management is needed to prevent river from polluted municipal wastewater. This research is a social analysis to investigate social perspectives on wastewater management planning. This analysis is imperative to find out the social response and willingness of the society towards municipal wastewater management. The social survey was carried out using the interview and questionnaire method. This research found that about 93% of the household already had water closets (WC) and 83% already had septic tanks. The problem that occurs is that the septic tank has never been sucked up because there is no desludging service. This is due to the fact that there are no Fecal Sludge Treatment Plant (FSTP) facilities in the Entikong Lama. Later, communal Wastewater Treatment Plant (WWTP) planning program was offered to the society. About 72% of the household agreed to the communal WWTP program and the rest refused or abstained. Even though it reached high positive response from the society, there were some considerations of the communal WWTP program: the location of the communal WWTP, the clarity of those who manage the wastewater plant and the amount of fees charged to the society.

Abstract

Limbah peternakan sapi di Desa Tekelan terdiri dari limbah padat, semi padat (slurry) dan limbah cair. Masyarakat memanfaatkan limbah padat untuk membuat kompos secara tradisional. Tujuan penelitian ini yaitu pengujian indeks perkecambahan sebagai indikator kematangan kompos. Teknologi alamiah (fitotosisitas) dapat digunakan untuk menjamin kualitas kompos. Teknologi ini bersifat sederhana, tidak memerlukan peralatan utama, biaya perawatan minimal, sampel yang diperlukan sedikit, tidak mengenal musim, benih mudah dibeli dimana-mana, benih bertahan lama, dan waktu perkecambahan cepat. Metode penentuan kematangan dan kestabilan kompos menggunakan uji indeks perkecambahan yang didasarkan pada nilai Germination Index (GI). Biji kacang hijau (Vigna Radiata) ditaburkan pada kapas yang dibasahi dengan ekstrak kompos. GI dihitung berdasarkan nilai perkecambahan relatif (G) dan panjang akar relatif (L). Hasil penelitian menunjukkan bahwa nilai GI kotoran sapi segar sangat rendah hanya sebesar 47, sedangkan kompos yang berumur seminggu memiliki nilai GI sebesar 58. Kompos kotoran ayam menghasilkan nilai GI 74. Ketiga kompos ini mengindikasikan bahwa kompos belum matang dan stabil (GI<80). Nilai GI kompos dengan waktu komposting 2, 3, dan 4 minggu >80 yang mengindikasikan bahwa kompos telah matang dan stabil.

Abstract

Di Indonesia, selain sebagai saluran air alamiah, sungai sering pula digunakan sebagai tempat pembuangan air limbah kegiatan rumah tangga (domestik). Penggunaan teknologi yang efisien dan alami merupakan solusi sederhana dan murah untuk mengolah air limbah domestik dengan sistem desentralisasi. Tujuan penelitian ini adalah mengolah air limbah domestik menggunakan IPAL portabel dengan dimensi kecil, sehingga aplikatif untuk skala rumah tangga. Penelitian dilakukan di Laboratorium Lingkungan, Departemen Teknik Lingkungan, Universitas Diponegoro selama 3 bulan. Metode penelitian menggunakan IPAL portabel untuk mengolah air limbah domestik skala rumah tangga dengan sistem kontinu. Limbah domestik berasal dari kantin kampus Universitas Diponegoro. IPAL portabel menggunakan sistem kombinasi anaerob-aerob yang dilengkapi dengan bak penampung limbah awal, bak penangkap lemak dan bak efluen. Waktu tinggal hidrolis atau Hydraulic Retention Time (HRT) dilakukan pada 3 variasi yaitu 4 jam, 8 jam dan 12 jam. Hasil penelitian menunjukkan bahwa konsentrasi amoniak mengalami penurunan terbesar pada HRT 12 jam dengan efisiensi penyisihan sebesar 60%. Konsentrasi awal sebesar 40,99 mg/l turun menjadi 16,4 mg/l. Konsentrasi Chemical Oxygen Demand (COD) dan minyak & lemak juga mengalami penurunan terbesar pada HRT 12 jam, masing-masing turun sebesar 71% dan 91% dari konsentrasi awal. IPAL portabel ini paling efektif dalam menyisihkan minyak & lemak.
