Abstract

Kesenjangan pada jumlah sampah yang dihasilkan tersebut dikarenakan oleh penanganan sampah yang umum dilakukan secara konvensional menggunakan cara pembuangan di tempat terbuka. Penyebabnya adalah terbatasnya sarana pengumpulan dan pengangkutan sampah. Hal ini akan mengakibatkan sisa atau sampah yang dihasilkan semakin banyak. Metode yang digunakan pada penelitian ini adalah metode Interpretative Structural Modelling (ISM). Metode ISM merupakan metode yang bisa membuktikan keterkaitan antar elemen yang ada. Metode ini bisa dikembangkan untuk merencanakan kebijakan strategis pengelolaan sampah. Strategi pengelolaan sampah di Kabupaten Bekasi dilaksanakan berdasarkan tingkat kepentingan dari suatu permasalahan. Dalam penelitian ini strategi utama yang perlu dilakukan yakni meningkatkan sumberdaya manusia, meningkatkan kesadaran masyarakat terkait pengelolaan sampah, teknologi pengelolaan sampah dilakukan secara efektif dan efisien serta menghasilkan energi terbarukan.

Abstract

Numerous environmental problems drive discussion to solve them. Students require environmental problem-solving skills to solve the existing problems. The study aimed to describe environmental problem-solving skills in Elementary Education. The research method is descriptive using a system dynamics approach. Instrument of Higher Order Thinking Skills (HOTS) and Pro-Environmental Behavior (PEB) used to measure students score in environmental topic. Sample was chosen by simple random sampling. The research used VENSIM software to create the modeling. The research results indicate that the score of the environmental problem-solving skills tends to increase due to the Higher Order Thinking Skills (HOTS) and Pro-Environmental Behavior (PEB). Moreover, there are other influencing factors including learning media and students’ activity in their environment. An increase of 5 points in the environmental problem-solving skills every year will be derived if the teachers perform various learning innovations. The research concludes that environmental problem-solving skills in low category and can be improve by various learning innovations.

Abstract

An Ecological drainage becomes an application in this development project in the Kelapa Gading area. The drainage concept that is applied is a drainage system in which rainwater that falls on road surface runoff will flow directly into the water infiltration system and directly fill the ground surface water. Geologically, it can be seen that North Jakarta is an area with a fairly high ground water level (MAT), and has an average MAT elevation of 2 - 2.5 m. This study intends to determine the ability of this ecodrainage to reduce runoff/floods that often occur in areas with a fairly high MAL. What direct benefits can be felt in the use of ecodrainage in these flood-prone areas, thus making the basic reason for applying this ecodrainage. This study uses a dynamic systems approach. In the preparation of the dynamic system model, Powersim Studio Version 10 software will be assisted. The simulation results show that an increase in rainfall every year will provide an increasing flood potential. By using eco-drainage, it is felt that it is not optimal enough to reduce runoff in areas that have high MAT levels. However, this ecodrainage still provides broad sustainability benefits. The quantity of groundwater will slowly be filled up to the aquier layer through this ecodrainage. This step is considered to be able to help prevent the aquifer layer from being exposed and have an impact on the rate of land subsidence so that the potential for flooding will decrease.

Abstract

Abstract Hypothesis testing is a material in the Statistics course that is very important for students and researchers, because it will be very useful when compiling a thesis, thesis, or research results. The procedure for drawing scientific conclusions which is carried out in stages, so that it can be accounted for to all parties, is called hypothesis testing. In testing the hypothesis, it is necessary to test assumptions about the distribution of the data. If the distribution assumption is met, then parametric hypothesis testing can be performed. If the distribution assumption is not met, a nonparametric hypothesis test is used. The need to improve the understanding of statistics and the proper procedure for drawing conclusions in research, is felt by partners, namely students and lecturers in LLDIKTI region III. The solution given is to provide training to selected lecturers and students on the procedure for drawing scientific conclusions in statistics. The target audience in this training are final year students and lecturers who are conducting research, in LLDIKTI Region III DKI Jakarta, totaling 136 people. The training is conducted online and focuses on discussing the steps for preparing hypothesis testing in research, including hypothesis testing procedures, test the hypothesis for a difference of 2 on average, test the hypothesis for a difference of more than 2 on average, test the correlation, and test the hypothesis in multiple regression. In this training, the devotees also provide training on the use of JASP software to test hypotheses. Evaluation is carried out on the level of understanding of the target audience before and after the activity using McNemar on testing level α = 5%. The results of the analysis of the questionnaire before and after the training obtained values 2=97.01 and  1;0,012 = 6.634 so it can be concluded that there was a significant increase in understanding before and after the training on hypothesis testing procedures in research. The results of the questionnaire after the training also show 88% of the target audience thought that the practice of JASP software was new knowledge gained in this training. Abstrak Uji hipotesis adalah materi dalam mata kuliah Statistika yang sangat penting bagi mahasiswa maupun peneliti, karena akan sangat berguna ketika menyusun skripsi, tesis, atau hasil penelitian. Prosedur penarikan kesimpulan secara ilmiah yang dilalukan secara bertahap, sehingga dapat dipertanggungjawabkan kepada semua pihak, disebut uji hipotesis. Dalam uji hipotesis perlu dilakukan uji asumsi tentang distribusi data. Jika asumsi distribusi dipenuhi, maka uji hipotesis parametrik dapat dilakukan. Jika asumsi distribusi tidak dipenuhi, digunakan uji hipotesis nonparametrik. Kebutuhan untuk meningkatkan pemahaman ilmu statistika dan prosedur pengambilan kesimpulan yang tepat dalam penelitian, sangat dirasakan oleh mitra, yaitu mahasiswa dan dosen di lingkungan LLDIKTI wilayah III. Solusi yang diberikan adalah memberikan pelatihan kepada dosen dan mahasiswa terpilih tentang prosedur penarikan kesimpulan secara ilmiah dalam statistika. Khalayak sasaran dalam pelatihan ini adalah mahasiswa tingkat akhir dan dosen yang sedang melakukan penelitian, di lingkungan LLDIKTI Wilayah III DKI Jakarta yang berjumlah 136 orang. Pelatihan dilakukan secara daring dan difokuskan pada pembahasan langkah-langkah penyusunan uji hipotesis dalam penelitian, meliputi prosedur uji hipotesis, uji hipotesis untuk beda 2 rata-rata, uji hipotesis untuk beda lebih dari 2 rata-rata, uji korelasi, dan uji hipotesis dalam regresi berganda. Pada pelatihan ini, pengabdi juga memberikan pelatihan penggunaan software JASP untuk uji hipotesis. Evaluasi dilakukan terhadap tingkat pemahaman khalayak sasaran sebelum dan sesudah kegiatan menggunakan uji Mc Nemar pada tingkat  = 5%. Hasil analisis dari jawaban kuesioner sebelum dan sesudah pelatihan diperoleh nilai 2 = 97,01 dan  1;0,012 = 6,634 sehingga dapat disimpulkan bahwa terdapat peningkatan pemahaman yang signifikan sebelum dan sesudah pelatihan tentang prosedur uji hipotesis dalam penelitian.

Abstract

Path analysis is an analytical method used to analyze direct and indirect effects between variables. This study uses path analysis to identify the direct or indirect effect of factors that are thought to nfluence life expectancy in the central part of Indonesia. The data used is secondary data and was obtained from BPS in 2017. The result of the model fit test show that the resulting model has a chi-square p-value of 0.121, indicating that the mdel is fit. In addition, the RMSEA (Root Mean Square Error of Approximation) value obtained is 0.087, which indicates a relatively small level of approximation error. The CFI (Comparative Fit Index) value obtained is 0.951 and the TLI (Tucker-Lewis Index) value obtained is 0.990. The results of the analysis show that there is a significant direct effect between the per capita expendicture and the average length of schooling on life expectancy. In addition, the average length of school variable also has an indirect effects on life expectancy through the per capita expenditure variable. This indicates that education has a positive impact on increasing per capita expenditure and ultimately contributes to an increase in life expectancy.
