Abstract

The Petanu River is one of the rivers in Gianyar Regency. The use of the Petanu river is for irrigation of rice fields, holy places, waterfall tourism, as the main function of domestic lime disposal and there is illegal sandstone mining in several Petanu river basins. The Petanu River is also used for the community's basic needs, namely bathing, washing and toilets. Based on these activities, it will certainly affect the water quality of the Petanu river. Based on storet method calculations, the Petanu river experiences moderate pollution. This was influenced by the phosphate parameter at the monitoring location in the middle of the Petanu River which exceeded the class II water quality standard with a concentration of 0.3 mL. The fecal coliform parameters were found in the middle monitoring location with a concentration of 2,400 MPN/100 mL, the downstream monitoring location was 1,500 MPN/100 mL which exceeded the threshold for class II water quality standards.

Abstract

The increasing population causes an increase in the amount, variety and characteristics of waste. Good waste processing and management is needed to deal with waste problems. TPS 3R Kesiman Kertalangu is an independent waste processing site in Kesiman Kertalangu Village. There is mixed and residual waste entering TPS 3R Kesiman Kertalangu. In processing the waste into compost, the waste is first sorted and shredded. In this research, several experiments were carried out to determine the maximum sorting and shredding speed. The water content of the waste studied included: 25%, 50%, 75%. The research method used is the experimental method. Determining the water content of waste is done first by observing the daily weather to obtain the desired water content. Apart from that, there is a wash out of sorting personnel in sorting waste to get accurate data, so that there is no carry over effect. Measuring shredding speed uses the SNI 7580:2010 approach as a reference that is close to the basis of research. Based on research results, waste water content of 25% is the maximum waste for sorting. Apart from that, waste with a water content of 25% is also the waste that is shredded the fastest.

Abstract

Angantaka Village, covers an area of approximately 239 hectares with a population of around 4,376 people and 1,458 households. According to SNI 19-3983-1995, Angantaka Village is classified as a small town with a population of less than 100,000. Waste management system in the village largely follows the traditional method of collect, transport, and dispose without any sorting. The main issues contributing to the waste problem in Angantaka Village include a lack of community awareness regarding proper waste management and the absence of adequate temporary waste disposal facilities. Most of the waste from Badung Regency, including Angantaka Village, is transported to the Suwung landfill. Therefore, composition, and characteristics of household waste, which would help in estimating the land requirements and the costs for constructing and operating a 3R (Reduce, Reuse, Recycle) waste processing facility. The study revealed that the average domestic waste generation is 0.6 kg per person per day, with wet waste, including food scraps and garden waste, amounting to 1,519.78 kg per day, and dry waste, such as plastics, paper, and metals, totaling 1,360.55 kg per day. This data is crucial for designing a 3R-based Temporary Waste Management Facility in Angantaka Village.

Abstract

Aspek desain ergonomis gagang pancing sangat mempengaruhi kenyamanan aktivitas orang-orang yang memiliki hobi memancing, baik itu kegiatan memancing yang dilakukan di sungai maupun kegiatan memancing yang dilakukan di laut lepas. Kesalahan posisi pada saat melempar umpan sampai pada penangkapan ikan, dapat mengakibatkan cidera maupun kelelahan otot. Kegiatan yang awalnya bertujuan untuk menyalurkan hobi dan menghilangkan penat, dapat berubah menjadi kecelakaan yang mengakibatkan cidera otot dan organ tubuh. Untuk meminimalisir hal tersebut diperlukan sebuah kajian ergonomis terhadap desain alat pancing, sehingga masyarakat yang memiliki hobi memancing dapat meminimalisir terjadinya cidera otot. Penelitian ini merupakan penelitian kualitatif dengan metode wawancara terhadap para pemancing di sekitar area Labuhan Amuk, Karangasem. Kajian terdahulu tentang memancing masih terbatas pada penggunaan umpan dan produktivitas tangkapan ikan, oleh sebab itu pustaka penunjang dikaitkan dengan terjadinya keluhan pegal pada jenis kegiatan tertentu terutama sektor informal. Penambahan gagang pancing bercabang ternyata dapat mengurangi timbulnya keluhan pegal saat memancing, hal ini sesuai dengan hasil wawancara yang dilakukan dengan penghobi mancing. Berdasarkan hasil pengamatan lapangan, diperoleh temuan bahwa penggunaan gagang pancing modifikasi dapat menurunkan rasa lelah otot.

Abstract

Sampah pasar merupakan salah satu sumber limbah organik yang dapat didaur ulang menjadi kompos, biogas (metanisasi), maupun pakan ternak. Sampah pasar memiliki karakteristik yang berbeda dengan sampah rumah tangga. Komposisi sampah pasar didominasi oleh limbah organik, terutama berasal dari pedagang sayur dan buah. Dampak lain dari aktivitas para pedagang di pasar adalah meningkatnya jumlah sampah seiring berkembangnya pasar dan kegiatan di dalamnya. Pasar Sembung yang terletak di Kecamatan Mengwi, Kabupaten Badung, merupakan pusat jual beli masyarakat dari 15 desa berdasarkan Peraturan Daerah Kabupaten Badung Nomor 3 Tahun 2017 tentang Penataan dan Pembinaan Pasar Rakyat, Pusat Perbelanjaan dan Toko Swalayan. Kondisi Pasar Sembung dengan beragam aktivitas penjual dan pembeli tentu menghasilkan limbah padat, termasuk limbah organik dan anorganik. Berdasarkan hasil observasi, Pasar Sembung belum memiliki sistem pengelolaan sampah yang efektif. Oleh karena itu, perlu direncanakan pengelolaan sampah di Pasar Sembung dengan pendekatan 3R (Reduce, Reuse, Recycle). Dari hasil perencanaan yang telah dilakukan, dibutuhkan luas lahan sebesar 385 m² untuk mendukung sistem pengelolaan sampah tersebut.
