Abstract

This research study the role of Family and Government Policy of Palangka Raya in Household Waste Managementin order to see whowas the most responsible for decision-makers in the process of waste management in households, and examines the role of families in the process of waste management before disposal into the trash. Data collection was done through observation and interview on the studied variables. The research was conducted in the district of Pahandut, district of Jekan Raya and district of Sebangau Palangka Raya in April till June 2011. The Source of data or respondents in the research community is engaged in managing and disposing of garbage. The community is a society of each chosen houshold. Sampling was done purposively stratified. The results showed that the head of the family was instrumental in the process of garbage disposal. Garbage disposal decision makers is the father of 68.9% (31 respondents) and the mothers of 31,1% (14 respondents). In the waste management at household level was the comparison between wet waste and dry waste that is equal to ⅓ most was 54% (7 respondents. This indicates that the household waste produced is a dry waste. Penelitian ini bertujuan untuk mengetahui peran keluarga dan kebijakan pemerintah Kota Palangka Raya dalam pengelolaan sampah rumah tangga agar dapat melihat siapa yang paling berperan sebagai pengambil keputusan dalam proses pengelolaan sampah di dalam rumah tangga, serta mengkaji peranan keluarga dalam proses pengelolaan sampah sebelum dibuang ke tempat sampah. Pengumpulan data dilakukan melalui pengamatan atau observasi (observation) dan wawancara (interview) terhadap variabel yang diteliti. Penelitian ini dilaksanakan di Kecamatan Pahandut, Kecamatan Jekan Raya dan Kecamatan Sebangau Kota Palangka Raya pada bulan April hingga bulan Juni 2011. Sumber data atau responden dalam penelitian adalah masyarakat yang terlibat dalam kegiatan pengelolaan dan pembuangan sampah. Masyarakat yang dimaksud adalah masyarakat dari masing-masing rumah tangga terpilih. Pengambilan sampel dilakukan secara purposive berstrata. Hasil penelitian menunjukkan bahwa kepala keluarga sangat berperan dalam proses pembuangan sampah, pengambil keputusan pembuangan sampah adalah Bapak sebesar 68,9% (31 responden) dan Ibu sebesar 31,1% (14 responden), Dalam pengelolaan sampah di tingkat rumah tangga ternyata perbandingan antara sampah basah dan sampah kering terbanyak adalah ⅓ yaitu sebesar 54% (7 responden). Hal ini menunjukkan bahwa sampah rumah tangga yang dihasilkan adalah berupa sampah kering.

Abstract

Sand mining activities can cause environmental changes and reduce water quality in abandoned mining ponds due to alterations in the physical and chemical characteristics of aquatic ecosystems. This study aimed to analyze the level of water pollution in former sand mining ponds located in Kalampangan Village, Palangka Raya City, based on physical and chemical parameters and the Pollution Index (PI). The study employed a quantitative descriptive method using primary data obtained from water quality measurements, including Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, copper (Cu), lead (Pb), and Chemical Oxygen Demand (COD). The analysis was conducted by comparing the measurement results with the water quality standards stipulated in Government Regulation Number 22 of 2021 and by calculating the Pollution Index (PI). The results showed that TSS and TDS concentrations complied with the applicable water quality standards, whereas several chemical parameters, including pH, Cu, Pb, and COD, exceeded the established limits. The low pH values indicated acidic water conditions, while the elevated COD levels suggested the presence of organic and inorganic pollutants in the water. Based on the Pollution Index (PI) calculation, all water samples were classified as slightly polluted. Therefore, environmental management measures such as liming, bioremediation, the utilization of aquatic plants, and aeration are recommended to improve water quality in former sand mining ponds.

Abstract

This study was conducted at PT Satria Alam Manunggal Site TOP to analyze the effect of road geometry conditions on the performance of Scania P410-B6x4 transport equipment in overburden material transportation activities. The haul route from the front to the disposal site is 2.4 km long, with an average hauler productivity of 33 BCM/hour, while the company's target is set at 40 BCM/hour. This situation indicates an issue with the hauler's travel time when transporting overburden material from the front to the disposal site, resulting in the hauler's productivity not being achieved. The analysis was conducted by dividing the haul road into 29 segments, consisting of 27 straight segments and 7 curved segments. The minimum width of straight roads is 9.1 meters for two lanes and 5.2 meters for one lane, while for curves, the minimum width is 16.29 meters and 9.31 meters, with a maximum road gradient (grade) of 8%, as well as other elements such as curve radius, superelevation, cross slope, safety berm, and drainage channels, also affect operational comfort and safety. The objective of this study is to evaluate and provide recommendations for road geometry improvements to meet technical standards, thereby reducing travel time and increasing transportation vehicle productivity.
