Abstract

ABSTRACT Caisim plants or mustard greens are plants with high nutritional content, used as ingredients for consumpting vegetables and medicines. The Consumption of caisim plants in Indonesia is quite large and evenly distributed throughout the region. This research aims to obtain a good planting media for development of caisim production. The planting media used in this study were soil, cocopeat, husk charcoal, and sand. Planting media was used to represent soil conditions in Indonesia. The research was carried out by planting caisim plants in polybags with drip irrigation systems and measurements on the 10th, 17th, 24th, and 31st days. The planting medium responds to the growth of caisim plants where the variable height of the planting media which influences the most sequentially is soil, cocopeat, husk charcoal, and sand. For the variable number of leaves in the planting medium it has no effect, but on the growth of leaf width and visually on the soil and cocopeat planting media the leaves grow wide and healthy, the rice husk charcoal planting medium is healthy but small, while the leaves on the sand planting medium tend to be small and wrinkled. This is due to the ability of the planting media to store nutrients and supply caisim plants. Increasing the effectiveness of caisim production at the household scale takes into account the factors of cropping patterns, narrow land use, and provision of irrigation water.

Abstract

Tanaman sawi caisim merupakan salah satu tanaman yang banyak dikonsumsi oleh masyarakat Indonesia karena digunakan sebagai bahan sayuran dan obat-obatan. Oleh karena itu diperlukan budidaya yang baik untuk mampu mengahasilkan produktifitas sawi caisim yang optimal. Tulisan ini mempelajari bagaimana cara budidaya tanaman caisim hidroponik pada skala rumah tangga dengan meninjau pengaruh ukuran polybag sebagai wadah media tanamnya. Media tanam yang digunakan yaitu cocopeat, karena cocopeat merupakan bahan organik yang mudah didapatkan dan bernilai ekonomis. Penelitian dilakukan dengan penanaman caisim pada polybag dengan sistem irigasi tetes. Pengamatan dilakukan terhadap morfologi tanaman caisim yaitu tinggi tanaman dan jumlah daun dengan cara pengukuran pada hari ke-10, 17, 24, dan 31. Hasil penelitian menunjukkan bahwa ukuran polybag ternyata berpengaruh terhadap pertumbuhan tanaman. Semakin besar ukuran polybag memberikan hasil tanaman yang lebih optimal. Hal ini dikarenakan kemampuan dari media tanam dengan ukuran polybag yang lebih besar dapat bekerja lebih efektif dalam proses pertumbuhan tanaman. Metabolisme yang terjadi di dalam tanaman berjalan dengan baik sehingga energi yang dihasilkan dan karbohidrat yang disuplai memenuhi untuk proses pertumbuhan tanaman.

Abstract

Kampus Politeknik Negeri Lampung dilalui oleh Sungai Way Kandis dan merupakan Daerah Aliran Sungai (DAS) dari Sungai Way Kandis. Penataan ruang kampus perlu mempertimbangkan letak wilayah kampus sebagai DAS Sungai Way Kandis tempat air mengalir dan tergenang, menjadikan wilayah kampus menjadi rawan terkena banjir. Penelitian ini dilakukan untuk mengidentifikasi potensi banjir di wilayah Kampus Polinela, mengidentifikasi potensi banjir pada wilayah kampus sesuai dengan wilayah administasinya dan sebagai dasar pengambilan kebijakan dalam pembangunan yang akan dilakukan. Proses identifikasi potensi banjir yang dilakukan memerlukan bahan yaitu peta administrasi, peta bentuk lahan, peta kelerengan, peta jenis tanah, peta curah hujan, dan peta jaringan drainase yang diolah menggunakan pendekatan geospasial dengan menggunakan ArcGIS 10.8. Hasil analisis dari perhitungan scoring dan overlay yang dilakukaan dapat disimpulkan bahwa Areal Polinela didominasi dengan kelas kerawanan banjir tinggi seluas 0,3435 km2 atau 98,14 persen dari keseluruhan luas Polinela. Sedangkan berdasarkan administrasi wilayah Polinela didominasi oleh kategori tinggi yang terletak di Kecamatan Natar Kabupaten Lampung Selatan seluas 0,2941 Km2 atau 84,03 persen dari keseluruhan luas areal Polinela. Penanggulangan untuk pencegahan banjir perlu dilakukan dengan melakukan konservasi di daerah hulu sungai secara terintegrasi dan Kampus Polinela yang merupakan DAS Sungai Way Kandis perlu melakukan kerjasama dengan instasi-instansi terkait untuk melakukan pencegahan terjadinya banjir.

Abstract

Access roads at Politeknik Negeri Lampung (Polinela) support mobility for students, lecturers, and staff. Thequality of these roads, particularly the level of damage, is a serious concern as it disrupts accessibility for students and staff.Additionally, this condition hinders academic activities and the overall operations of the campus. Adequate and appropriaterepair efforts are necessary to ensure comfort and safety within the campus environment, thereby better supportingacademic activities.The Bina Marga Method is an approach used to assess the level of road damage. The assessment isconducted using specific established criteria, such as road classification and the severity of damage. The data collected isthen analyzed to determine the priority order for repairs and maintenance plans.The access road to Polinela Campus is 1,616.4 meters long and has an average daily traffic volume of 1,011.5 passengercar units per hour, classifying it into traffic class 4. Based on the results of the analysis, the condition rating of the PolinelaCampus road is 6, indicating that the priority order for road management is 7. Under these conditions, routine maintenanceis required. The routine maintenance needed in this case includes patching holes and resurfacing the pavement.

Abstract

Restaurant wastewater is categorized as domestic wastewater. It contains high levels of fats, spices, detergents, and cleaning agents, all of which can pose substantial environmental hazards if inadequately treated. This study compared the effectiveness of slow sand filters with various thicknesses of filter material and measured physical and chemical parameters, employing a combination of natural filter media, including gravel, silica sand, zeolite, and coconut fiber. The study assessed several water quality parameters, including pH, ammonia concentration, temperature, turbidity, and dissolved oxygen (DO). The results indicate that the filtration system effectively reduced ammonia concentrations to levels that comply with the regulatory standards. Parameters pH values had minor changes, they remained below the thresholds required by applicable regulations. A substantial reduction in turbidity was observed, while the effluent temperature remained within acceptable environmental limits. However, a decrease in DO levels was noted post-filtration, due to microbial activity and temperature dynamics within the filtration media. Overall, the findings suggest that slow sand filtration systems utilizing natural and locally available materials offer a low-cost, and environmentally sustainable alternative for the treatment of restaurant wastewater.
