Groundwater Processing Equipment into Clean Water with a CombinationProcess of Aeration-Upflow Filtration (a Design). In areas that have not received clean water services, residents usually use well water, river water which sometimes even often the water used does not meet the standards of healthy clean water. To treat well water/ ground water is usually the community. build a processing unit in the form of a sand filter. The problem that is often encountered in treatment is cleaning the filter media. This condition is often difficult for the community to do because it requires time and energy, resulting in the sand filter that is supposed to be operational continuously and finally stops and is not even used at all. To overcome this problem, it can be done by improving the design of water treatment units with a system of combination of aeration and upflow flow filtration. This study is to determine the ability of the tool to improve the quality of shallow groundwater in terms of turbidity, Fe, Mn, color and odor to clean water and saturation point of filtering. Research Design is a "quasi-experiment" in the form of "Time Series Design" using a "pre and post test" design without control. The tool is designed in the form of an application prototype to determine its ability to reduce turbidity, Fe, Mn, color and odor and the length of saturation point. The results showed that iron content before processing 2.12 after processing 2,058. pre-treatment manganese content 0.080 after processing 0.078. Color and smell before color processing and odor after processing are colorless and odorless. Microbiological quality for stool coly before processing week 1 32 after treatment 0, week 2 coly of feces before processing 26 after processing 0 and weeks 3 coly of feces before processing 21 and after processing 0. Length of processing up to saturation point filter media total contact time processing is 30 minutes. Bangun). Untuk mengolah air sumur/air tanah biasanya masyarakat membangun unit pengolahan berupa saringan pasir. Masalah yang sering ditemui dalam perawatan adalah pembersihan media saring. Kondisi ini sering sulit dilakukan oleh masyarakat karena membutuhkan waktu dan tenaga sehingga mengakibatkan saringan pasir yang seharusnya beroperasional secara terus menerus akhirnya terhenti dan bahkan tidak digunakan lagi. Untuk menanggulangi masalah tersebut, dapat dilakukan dengan cara memperbaiki rancang bangun unit pengolahan air dengan sistem kombinasi aerasi dan filtrasi aliran ke atas (upflow). Tujuan penelitian mengetahui kemampuan alat dalam memperbaiki kualitas air tanah dangkal dari segi kekeruhan, Fe, Mn, warna dan bau menjadi air bersih serta titik jenuh penyaringan. Desain penelitian"eksperimen semu" berupa "Time Series Design" menggunakan rancangan "pre and post-test" tanpa kontrol. Alat dirancang berupa prototype secara aplikatif guna mengetahui kemampuannya dalam menurunkan kekeruhan, kadar Fe, Mn, warna dan bau serta lamanya titik jenuh. Hasil penelitian menunjukkan bahwa kadar zat besi besi sebelum pengolahan...
Tapioca industrial waste is still a problem and needs to be treated before being discharged into water bodies. The waste generated can be in the form of solid waste, gas waste, and liquid waste. This research is an experimental study and uses tapioca industrial wastewater samples which previously measured the parameters of TSS, BOD, COD, PH, and odor. Then processing is carried out by flowing continuously into the processor with multilevel electro flocculation technology, a combination of activated charcoal sand media with 12-volt electric current using control without activated charcoal sand media. The purpose of the study was to determine the electro flocculation ability of the combination of sand-activated charcoal media (thickness variations of 20cm, 40cm, 60cm, 80cm) in processing tapioca waste. The results showed a decrease in the levels of TSS, BOD, COD, pH, and odor. The most effective reduction was in the variation of activated charcoal sand media with a thickness of 60 cm. The results of the statistical test showed differences in the level of reduction in the pollutant content of tapioca waste TSS, BOD, COD, pH, and odor in the multistage electro flocculation process in the combination of sand–activated charcoal media with a p-value=0.00. The results of the study can be used as an alternative in the processing of tapioca industrial wastewater.
Telang flower is a plant that has a health effect on the body. 10% telang flower can be used as a natural food coloring. Steamed cake is also a traditional food favored by community. Steamed cake usually uses synthetic food coloring to attract the consumers. This study aimed to examine the antioxidant capacity, chemical characteristics, and organoleptic properties of steamed cake with the addition of extract and petals of telang flower. This research using experimental approach conducted in April–December 2020. The product analyzed for antioxidant capacity using total phenol and DPPH methods, chemical characteristics with proximate analysis, and organoleptic properties using hedonic and rankings hedonic. Data were analyzed using ANOVA with Duncan Multiple Range Test. The results were the extract and petals of telang flower significantly affected the total phenol content and antioxidant activity of steamed cake with relatively fluctuating values. In addition, the addition of telang flower extract and petals in steamed cake increased the water content but decreased the fat content significantly, decreased the protein and ash content not significantly. While the value of fiber and carbohydrates are relatively fluctuating. Telang flower extract and petals also had no effect on sensory attributes such as color, taste, aroma, and texture of steamed cake. The products are liked by panelist. It was concluded that telang flower can be used as food coloring for steamed cake without changing the product’s organoleptic properties.
Sanitasi Total Berbasis Masyarakat (STBM) merupakan pendekatan untuk mengubah perilaku higienis dan saniter melalui pemberdayaan masyarakat dengan cara pemicuan (Permenkes RI, No.3, Th. 2014). Program STBM memiliki indikator outcome dan output. Indikator outcome STBM yaitu menurunnya kejadian penyakit diare dan penyakit berbasis lingkungan lainnya yang berkaitan dengan sanitasi dan perilaku. Desa Rejosari dengan jumlah penduduk 5.506 jiwa yang terbagi menjadi 8 Dusun merupakan salah satu desa di Kecamatan Natar Kabupaten Lampung Selatan, dimana desa tersebut telah dapat mewujudkan komunitas yang bebas dari buang air di sembarang tempat (ODF), Sedangkan Desa Negara Ratu yang berpenduduk 10.442 jiwa yang berditempat tinggal di 14 Dusun belum dapat mencapai desa ODF, dan langkah selanjutnya akan melakukan kegiatan menjadikan wilayah STBM. Pencapaian pengabdian pada masyarakat dilakukan dengan melakukan sosialisasi program dan penyuluhan mulai tingkat kecamatan, desa dan dusun sasaran serta yang bertujuan memberikan pemahaman kepada masyarakat tentang STBM dan membentuk kader kesehatan yang mampu membangun desanya menjadi desa sehat, sehingga dengar sadar masyarakat dapat membuat sarana sanitasi dasar dalam rangka mencapai Sanitasi Total Berbasis Masyarakat yang meliputi indicator outcome dan output tersebut diatas. Dari hasil kegiatan pengabdian kepada masyarakat dengan pendekatan kepada Kepala Desa, Kepala Dusun dan warga sasaran terdapat peningkatan pemahaman tentang STBM, akan tetapi belum terbentuk organisasi masyarakat berkaitan dengan kelompok STBM tersebut. Selain peningkatan terhadap pemahaman STBM, juga ada peningkatan cakupan sarana sanitasi, diantaranya pembangunan 15 sarana jamban keluarga, 7 sarana pembuangan air limbah rumah tangga, 20 sarana CTPS, dan 10 sarana pembuangan sampah. Pencapaian pengabdian kepada masyarakat belum optimal, hal ini karena kondisi sosial ekonomi masyarakat yang masih rendah, serta partisipasi gotong royong membangun desa belum mengarah kepada kegiatan STBM.
