"Sebagai salah satu kontributor utama gas emisi yang mengakibatkan perubahan iklim, industri energi semakin didorong untuk beralih ke penggunaan energi terbarukan. Di Indonesia, PLTS atap rumah tangga diharapkan pemerintah untuk menjadi penopang utama upaya transisi industri energi bahan bakar fosil ke energi baru terbarukan. Sayangnya, upaya tersebut menemui beberapa hambatan, utamanya dari kondisi sosial dan kondisi PLN, BUMN yang mengendalikan industri kelistrikan di Indonesia. Maka dari itu, dilakukan analisis skenario dengan basis model sistem dinamis untuk mengkaji dampak penetrasi PLTS atap rumah tangga dalam beberapa kondisi terhadap PLN dan bagaimana Pemerintah dapat mencapai target bauran energi dan juga lingkungan yang ditetapkan. Analisis pada penelitian menunjukkan bahwa resiliensi PLN terhadap adopsi PLTS atap rumah tangga jauh lebih tinggi dari prakiraan, sedangkan target bauran energi dengan PLTS atap rumah tangga sama sekali tidak tercapai. Hal ini menimbulkan sebuah gagasan rekomendasi akan bagaimana Pemerintah Indonesia harus merancang kebijakan pada kedepannya untuk mengejar target Indikator adopsi PLTS atap rumah tangga dan target indikator lingkungan sembari tetap menjaga keberlanjutan PLN.

As one of the main contributors of gas emissions that cause climate change, the energy industry is increasingly being encouraged to switch to the use of renewable energy. In Indonesia, the government expects household rooftop PVs to become the main support for the transition of fossil fuel energy industry to renewable energy. Unfortunately, these efforts encountered several obstacles, mainly from social barriers and PLN, the state-owned enterprise that controls Indonesia’s electricity industry. Therefore, a scenario analysis was carried out on the basis of a system dynamics model to examine the impact of household rooftop PV – under several conditions – on PLN and how the Government can achieve its energy mix and environmental targets. The analysis in the study shows that the resilience of PLN is much higher than forecasted, while the energy mix target with household rooftop PV is not achieved at all. This gave rise to a recommendation on how Indonesia’s government should design policies in the future to pursue the target of household rooftop PV adoption indicators and environmental indicators targets while maintaining the sustainability of PLN."

"Escherichia coli merupakan bakteri yang umum digunakan sebagai parameter terkait cemaran tinja dan sanitasi. Keberadaan nitrat pada air juga menjadi salah satu indikator terkait sanitasi. Beberapa penelitian menunjukkan bahwa sanitasi dapat mempengaruhi konsentrasi TDS (Total Dissolve Solids) dalam air tanah. Adanya kandungan E .coli, nitrat, dan TDS berlebih dalam air tanah yang digunakan sebagai air minum rumah tangga dapat berdampak pada kesehatan. Penelitian ini bertujuan untuk menganalisis hubungan antara kondisi sanitasi rumah tangga dengan kualitas air minum rumah tangga bersumber air tanah berdasarkan parameter E .coli, nitrat, dan TDS. Kondisi sanitasi yang diteliti meliputi 7 aspek, yaitu sarana buang air besar, tempat pembuangan akhir tinja, jarak tempat pembuangan akhir tinja, tempat pembuangan sampah rumah tangga, jarak TPS/TPA terdekat, sarana pembuangan limbah cair rumah tangga, serta jarak sarana pembuangan limbah cair rumah tangga. Penelitian ini menggunakan data sekunder dengan metode cross sectional. Analisis dilakukan dengan uji univariat dan uji bivariat menggunakan uji chi square dengan tingkat kepercayaan 90%. Hasil penelitian menunjukkan bahwa ada hubungan signifikan antara tempat pembuangan akhir tinja dengan kandungan TDS (p=0.086), tempat pembuangan sampah dengan cemaran E. coli (p=0.054), dan jarak TPS/TPA terdekat dengan kandungan TDS (p=0.061). Disarankan bagi peneliti selanjutnya untuk menganalisis lebih lanjut mengenai keterkaitannya dengan kesehatan.

Escherichia coli is a commonly used bacteria as a parameter related to fecal contamination and sanitation. The presence of nitrate in water is also an indicator related to sanitation. Several studies show that sanitation can affect concentration of TDS (Total Dissolve Solids) in groundwater. So, the presences of E. coli, nitrate, and TDS in groundwater that used as daily needs household drinking water can affect human health. This study aims to analyze the relationship between seven household sanitation conditions and the quality of household drinking water from groundwater based on the presence of E. coli, nitrate, and TDS as the parameters. The sanitation conditions include 7 aspects, such as defecation facilities, faecal disposal sites, the distance between feces disposal sites and drinking water sources, household waste disposal sites, the distance between household and temporary storage sites (TPS)/Final Processing Sites (TPA), household waste water disposal facilities, and the distance between household waste water disposal facilities and drinking water source. This research uses secondary data with a cross sectional analysis method. The analysis was carried out with univariate test and bivariate test using chi square test with a confidence level of 90%. The research results showed that there was significant relations between faecal disposal sites and TDS (p=0.086), waste disposal sites and E. coli (p=0.054), the distance to the nearest waste disposal sites and TDS. Therefore, the suggestions for further researcher to analyze the relations with health.

"This study investigates the interregional district-level inequalities and the spatial associations of household access to sustainable water and sanitation in Indonesia between 2004 and 2018. The findings show that although the gap of household access to water and sanitation declined over years, the disparities among districts in Indonesia kept persisting. Related to proliferation, the access in the districts that never separated is higher than in others. Furthermore, this study also confirms the presence of spatial cluster/outlier of accesses, although it remains very weak. The majority of districts with high access are clustered in the western part of Indonesia, especially in Java island. At the same time, in the mountainous areas of Papua island and some districts in Sumatera island where forest land has been degraded into plantation and mining areas have relatively low access for years. These left-behind districts need government attention and s"
