  • Pengaruh Penambahan Octane Booster dan Minyak Atsiri dalam Biosolar
           terhadap Performa Mesin Diesel

    • Authors: Okky Husnan Arya Utomo, Samsudin Anis
      First page: 36
      Abstract: Tujuan dalam penelitian ini adalah untuk mengetahui pengaruh penambahan octane booster dan minyak atsiri dalam campuran biosolar terhadap performa mesin diesel. Penelitian ini menggunakan metode penelitian eksperimen. Bahan baku yang digunakan adalah octane booster dan minyak atsiri. Dalam penelitian ini dipaparkan hasil pengujian performa mesin diesel dengan menggunakan dinamometer dengan variasi bahan bakar minyak fraksi diesel dari octane booster dan minyak atsiri dalam campuran biosolar yang meliputi performa mesin diesel berupa torsi dan daya. Penelitian ini dilakukan untuk menganalisis unjuk kerja mesin yang paling optimum dalam penggunaan variasi campuran minyak fraksi diesel dengan bisolar. Hasil penelitian menunjukkan campuran minyak biosolar dengan octane booster dan minyak atsiri berpengaruh pada torsi. Rerata torsi yang dihasilkan oleh mesin diessel telah meningkat setelah dilakukan penambahan octane booster dan minyak atsiri. Torsi yang dihasilkan oleh putaran mesin yang menjadi acuan peneliti yaitu 3500 rpm mengalami peningkatan yaitu sebesar 115,60 Nm dibandingkan dengan biosolar murni pada putaran mesin yang sama dengan 112,77 Nm yaitu pada campuran bahan bakar C4 dengan perbandingan 0,8% + 0,1%. Daya berbanding lurus dengan torsi, maka campuran minyak biosolar dengan octane booster dengan minyak atsiri mempengaruhi daya. Rerata daya yang diperoleh dalam mesin diesel meningkat setelah penambahan octane booster dan minyak atsiri. Daya putaran mesin hasil penelitian yang menjadi acuan peneliti yaitu 3500 rpm mengalami peningkatan yaitu sebesar 42,58 kW dibandingkan dengan biosolar murni pada perputaran mesin yang sama yaitu sebesar 41,34 kW yaitu pada campuran bahan bakar C3 dengan perbandingan 0,8% + 0,3%.

  • Voltammetric Analysis of Pb2+ Ion on Gold Nanoparticles-Modified ZnO
           Electrode

    • Authors: Rahmi Fauziah, Cepi Kurniawan
      First page: 46
      Abstract: Waste such as heavy metal is a very dangerous toxic material, the heavy metal that is often used is lead (Pb). In this study, heavy metal detection was carried out with the material used, namely ZnO because it has high sensitivity in heavy metal detection. ZnO will be modified with gold nanoparticles (AuNP). AuNP has been used for surface decoration of oxides to obtain high sensor performance which is 6.5 times faster than without the addition of Au. Research has been carried out on the Voltammetric Analysis of Pb2+ Ion on Gold Nanoparticles-Modified ZnO Electrode. This study aims to determine the nature and characteristics of the ZnO/AuNP compound deposited on the SPCE electrode and to determine the selectivity and sensitivity of the ZnO/AuNP electrodeposition on the SPCE electrode to identify heavy metals. FTIR characterization showed that there was a Zn-O bond in the synthesized compound. SEM characterization showed hexagonal morphology. The PSA results showed the size of the AuNP was 115.7 nm. The test results of the ZnO/AuNP5%/SPCE electrode sensor have a LoD value of 2.88 ppm and a LoQ of 9.60 ppm, a sensitivity of 0.077 µA µg-1 L., and R2 = 0.96862.

  • Analisis Kandungan Logam Berat Cadmium (CD) pada Udang Putih (Penaeus
           merguiensis) di Perairan Sungsang Provinsi Sumatera Selatan

    • Authors: Yunita Panca Putri, Inka Dahlianah, Ita Emilia
      First page: 59
      Abstract: Aktivitas penduduk  Sungsang Kabupaten Banyuasin Provinsi  Sumatera Selatan cenderung lebih banyak di perairan. Berbagai aktivitas tersebut memiliki kecenderungan untuk membuang limbah ke aliran air sehingga limbah tersebut akan terakumulasi. Akumulasi limbah ini akan menyebabkan pencemaran lingkungan sehingga menjadikan hal ini sebagai masalah yang perlu diperhatikan. Salah satu jenis logam berat yang memasuki perairan dan bersifat toksik adalah kadmium (Cd). Analisis kandungan logam berat pada biota seperti udang perlu dilakukan, hal ini disebabkan kandungan logam berat dalam air yang dapat berubah-ubah dan bergantung pada lingkungan. Tujuan dalam penelitian ini adalah untuk untuk  mengetahui kualitas perairan Sungsang melalui  konsentrasi  logam berat Cd pada sedimen dan  konsentrasi logam berat Cd pada udang putih (Penaeus merguiensis).  Kandungan logam berat Cd  pada sedimen di perairan Sungsang masih memenuhi Standar Baku Mutu menurut Swedish Environmental Protection Agency dan Kandungan Cd pada udang putih (Penaeus merguiensis) di perairan Sungsang belum melebihi batas yang ditetapkan oleh Kepala BPOM RI No HK.00.06.1.52.4011

  • Metode Stochastic Frontier Analysis untuk Mengukur Efisiensi di Sektor
           Pendidikan

    • Authors: M. Mujiya Ulkhaq
      First page: 65
      Abstract: Efisiensi menjadi salah satu ukuran performansi pada suatu institusi pendidikan. Secara umum, efisiensi didefinisikan sebagai rasio dari output dan input. Pada sektor pendidikan, efisiensi diartikan sebagai ukuran kinerja suatu entitas pendidikan (siswa, sekolah, universitas, bahkan sistem pendidikan suatu negara) untuk menghasilkan suatu output dengan menggunakan input yang ada. Pada literatur ekonomi pendidikan, terdapat dua metode yang sering digunakan untuk mengukur efisiensi, yaitu data envelopment analysis (DEA) dan stochastic frontier analysis (SFA). Penelitian ini membahas metode SFA untuk mengukur efisiensi pada sektor pendidikan dan keuntungan yang didapatkan dibanding apabila menggunakan metode DEA. Fungsi produksi yang kerap digunakan untuk mengukur efisiensi juga akan dibahas di sini. Selain itu, penelitian ini juga akan menampilkan variabel-variabel (input dan output) yang digunakan di literatur untuk mengukur efisiensi pada sektor pendidikan. Penelitian ini diharapkan dapat lebih memperkenalkan metode SFA (khususnya pada peneliti di Indonesia) yang mempunyai berbagai keuntungan namun kurang populer dibandingkan dengan metode DEA.

  • Qualitatife Test of Papaya Leaves, Cassava Leaves, and Melinjo Leaves as
           Alternative Ingredients for Foods Rich in Vitamin C for the Community

    • Authors: Ariska Septiyani Susanti, Rina Rahayu
      First page: 74
      Abstract: One of the roles of vitamin C in the body is as an antioxidant compound that can counteract free radicals, besides that vitamin C also acts as an immunomodulator that stimulates neutrophil migration, forms oxidants, kills microbes and increases phagocytosis. In addition, vitamin C can reduce the risk of complications in patients who have been exposed to COVID-19, reduce the risk of contracting it, prevent symptoms from appearing and can increase the body's resistance or immunity. The purpose of this study was to determine the presence of vitamin C in papaya leaves (Carica papaya), cassava leaves (Manihot Esculenta), and melinjo leaves (Gnetum gnemon) which can be used as alternative foods rich in vitamin C for the community. This research was conducted with a qualitative method. From the results of observations, the three samples showed positive results for vitamin C. With the results of this study, it is hoped that it can be used as an alternative food ingredient for the community to meet their daily vitamin C needs, especially during the Covid-19 Pandemic like now vitamin C is needed to increase the body's resistance so that it does not susceptible to various diseases.
