Abstract

ABSTRAKPabrik Kelapa Sawit (PKS) yang dimiliki PT. Grahacipta Bangko Jaya (GBJ) memiliki kapasitas terpasang sebesar 52 ton TBS (Tandan Buah Segar)/jam.  PKS  PT.  GBJ  terletak  di  Desa  Karang  Anyar,  Kecamatan  Pemenang Barat, Kabupaten Merangin, Provinsi Jambi.  Pabrik  beroperasi  selama  20  jam  sehari  selama  330  hari  per  tahun.  Sumber sawit  diperoleh  dari  perkebunan  milik  sendiri  seluas  600  hektar  dan  beberapa perkebunan plasma milik rakyat. Pabrik ini menghasilkan CPO sebanyak 10 ton/jam. Laju alir limbah POME selama Agustus 2016 sebesar 34.000 m3. Limbah cair sawit (Palm Oil Mill Effluent/POME) diambil dari keluaran fat pit menuju cooling  pond  1  dengan  kandungan  COD  rata-rata  sebesar  49.500  ppm,  TSS  19.750 ppm, FOG 118,57 ppm, pH 4-5 dan suhu 55oC.. Dari kolam tersebut POME dialirkan menuju  lokasi  pembangkit  listrik  biogas  (PLTBg)  yang  terletak  sejauh  ±300  m  dari lokasi pengambilan limbah POME di lokasi pabrik. Lahan  pembangunan  PLTBg  memiliki  kondisi  tanah  berupa  lempung  sedang  yang cukup  baik  untuk  pembangunan  PLTBg  POME.  Dengan  mengetahui  sifat  kepadatan lempung  sedang,  perlu  diperhatikan  daya  dukung  tanah  agar  struktur  tidak mengalami kegagalan. Listrik  yang  dihasilkan  akan  didistribusikan  secara on-grid  ke  jaringan  PLN  dengan jarak  ke  jaringan  tegangan  menengah  dekat  dari  lokasi  yang  disediakan.  PLTBg  di  Kabupaten  Merangin  akan  menggunakan  teknologi  konversi  COD  berupa modified  covered  lagoon yang  dilengkapi  dengan  peralatan  gas  treatment untuk mempersiapkan  biogas  memasuki  gas  engine.  Gas  engine  yang  digunakan  memiliki kapasitas  2x600  MWe. Kata Kunci : PLTBg, CPO ABSTRACTPalm Oil Factory (PKS) owned by PT. Grahacipta Bangko Jaya (GBJ) has an installed capacity of 52 tons FFB (Fresh Fruit Bunches) / hour. PKS PT. GBJ is located in Karang Anyar Village, District of West Winner, Merangin District, Jambi Province. The plant operates for 20 hours a day for 330 days per year. The source of palm is obtained from its own 600 hectare plantation and several smallholder plasma estates. This factory produces CPO of 10 tons / hour. POME's waste flow rate during August 2016 was 34,000 m3. Palm Oil Mill Effluent (POME) is taken from fat pit output to cooling pond 1 with average COD content of 49.500 ppm, TSS 19.750 ppm, FOG 118.57 ppm, pH 4-5 and temperature 55oC .. From The pool is piped to the location of biogas power plant (PLTBg) located ± 300 m from the location of POME waste at the factory site. The land of PLTBg development has good soil clay condition which is good enough for PLTBg POME development. By knowing the properties of medium clay density, it is necessary to note the carrying capacity of the soil so that the structure does not fail. The electricity generated will be distributed on-grid to the PLN network with the distance to the near medium voltage network from the provided location. PLTBG in Merangin District will use COD conversion technology in the form of modified covered lagoon equipped with gas treatment equipment to prepare biogas entering gas engine. The gas engine used has a capacity of 2x600 MWe. Keywords: PLTBg, CPO

Abstract

In the current era of independent curriculum learning, the use of media in learning is very relevant to learning the differentiation of each student. This study aims to examine the correlation between the use of learning media in the form of flannel boards, with creative thinking and student learning outcomes The results of this study are the application of batik flannel board media is significant with the results of the creativity of control class students (who are not subjected to variables) is to reach an average score of 66.4 below the completeness number 75 while the results of the creativity of experimental class students (who are subjected to variables) is to reach an average score of 83.5 above the completeness number 75 with the One Sample Kolmogorov-Smirnov Test normality test. While based on the results of the understanding of the control class students reached an average score of 66.4 below the completeness number 75 while the results of the understanding of the experimental class students, namely the class subjected to the batik flannel board media, reached an average score of 83.5 above the completeness number 75 with the One Sample Kolmogorov-Smirnov normality test, with the significance test above 0.05, meaning that the data is normal. In conclusion, the implementation of Batik Flannel Board media can increase creativity and understanding of the concept of Mathematical Comparison material in grade V elementary school students.

Abstract

The results of the 2022 International Student Assessment (PISA) indicate that Indonesian students' creativity still requires serious attention. Therefore, this study aims to examine the implementation of differentiated PjBL learning to develop students' creative thinking skills in designing a power plant using Canva in elementary school students. This research was conducted experimentally using a "Pretest Post-test Control Design" design. The treatment was the implementation of differentiated PjBL learning with a project to design a power plant using Canva in class 4A (28 students), and the control was class 4B (28 students) with the same project but learning without differentiated PjBL. Measurement of students' creative thinking skills was carried out through pretests and post-tests covering indicators of fluency, flexibility, originality, and elaboration. The results of the One-Way ANOVA analysis followed by LSD showed that the pretest between the experimental and control groups did not differ significantly. However, the post-test scores of the experimental group were significantly higher than those of the control group. The results of the Mann-Whitney analysis of all indicators of students' creative thinking abilities prove that the pretest scores between the experimental group and the control group for all indicators are not significantly different. However, the post-test scores of the experimental group for all indicators are significantly higher than the control group. It is concluded that the implementation of differentiated PjBL learning is significantly able to develop students' creative thinking abilities in designing power plants through Canva in Elementary School Students.

Abstract

Kehalalan sebuah produk menjadi salah satu hal yang sangat penting bagi umat muslim dalam mengkonsumsi sebuah produk, karena kewajiban setiap muslim harus sesuai dengan ajaran yang telah ditetapkan yaitu harus mengkonsumsi makanan yang halal dan baik (Toyib). Setiap pelaku usaha harus menjamin kehalalan dari produk yang ditawarkannya sehingga perlu adanya sertifikasi halal. Namun masih banyak pelaku usaha yang belum memiliki sertifikasi halal atas produknya. Saat ini ada banyak Lembaga Pemeriksa Halal (LPH) di Indonesia yang sebelumnya hanya tunggal dilakukan oleh LPPOM MUI. Persaingan ini mengharuskan LPPOM MUI untuk memiliki strategi pemasaran yang kuat agar tetap menjadi lembaga yang dipilih oleh banyak pelaku industri dan pemilik merek mendaftarkan Sertifikasi halalnya melalui LPPOM MUI untuk diteruskan kepada BPJPH. Bauran pemasaran adalah seperangkat alat pemasaran yang digunakan perusahaan untuk terus-menerus mencapai tujuan pemasarannya dalam pasar sasarannya. Bauran 7P terdiri dari beberapa atribut yaitu product, price, promotion, place, process, people, dan physical evidence. Berdasarkan hasil penelitian mengenai bauran pemasaran 7P dapat dilihat bahwa pelanggan memiliki presepsi yang baik terhadap proses registrasi pendaftaran sertifikasi halal di LPPOM MUI DKI Jakarta. Atribut dengan tingkat kepentingan tertinggi menurut hasil analisis yaitu atribut people, process, dan product, sehingga ketiga atribut ini menjadi fokus utama dalam perbaikan strategi pemasaran di LPPOM MUI agar dapat menjadi lembaga yang dipilih oleh para pelaku usaha.
