Abstract

Penelitian ini bertujuan untuk mengetahui kandungan nutrisi Spirulina platensis yang dikultur pada media Walne, teknis dan kontrol. Kelimpahan S. plantesis tertinggi dicapai pada kuitur dengan media walne, demikian juga kandungan protein, karbohidrat, air, abu dan lemaknya. Pada media Walne, kandungan protein, karbohidrat dan lemak S. plantesis berturut-turut sebesar 50,05±0,53; 15,48±0,47; dan 0,51±0,12%. Sedangkan, pada media teknis, kandungan protein, karbohidrat dan lemak pada S. plantesis berturut-turut adalah 16,23±0,4; 12,57±0,22; dan 0,18±0,03%.  Perbedaan ini disebabkan oleh kandungan nutrient yang ada pada media kuitur.Kata kunci : Spirulina platensis, media walne, media teknis, nutrisi

Abstract

Zuhud adalah menghilangkan kecintaan terhadap sesuatu yang bersifat duniawi yang dapat melalaikan manusia untuk mengingat Allah. Dengan sifat dunia yang bersifat candu tersebut, dapat membuat manusia lupa akan mengingat Allah dan mengutamakan sesuatu yang bersifat duniawi, dalam bentuknya juga dapat dilihat dari perkembangan zaman yang terus berubah. Tujuan penelitian ini adalah untuk mengetahui pandangan zuhud dalam masa sekarang dalam Al-Qur’an melalui tafsir Al-Nûr. Peneliti menggunakan metode kualitatif, dengan jenis penelitian kepustakaan,  dan untuk metode analisis data menggunakan deskriptif-analitik. Hasil penelitian yang terkandung dalam tulisan ini menurut Hasbi Ash-Shiddieqy zuhud tidak hanya diartikan sebagai hal yang menjauh dari hal duniawi, akan tetapi menjadikan hal bersifat duniawi tersebut sebagai jalan menuju ketaatan kepada Allah. Adapun aplikasi zuhud diera modern menurut Hasbi Ash-Shiddieqy dimana seseorang memiliki sifat kesederhanaan, kesabaran, wara’, dan keseimbangan hidup dalam hidupnya.

Abstract

The road to preaching has a variety of ways, especially the media used. Among them is through the type of Nasyid religious music media. Among the Nasyid groups whose songs contain calls for Islamic da'wah are the Nasyid Hijjaz Group with the song "Mata Mata". From the observations of the author in it the message of the values of da'wah is stored, that believing Muslims are subject to the obligation to always improve the condition of their heart. The Eye View song, illustrates that a Muslim is required to improve the condition of the heart by purifying him from the filth of immorality that leads to the valley of sin. Giving birth to humiliation and addiction, the sins of the heart that make the heart become rusty. If sin through immorality continues to grow, then rust will dominate until it becomes the closing. While leaving immorality is life for the heart. Sin also diverts the heart from its health and straightness to pain and abuse. He will continue to be sick, unable to benefit from the parts that support his life and piety. The heart is the captain of the faithful servant who is the main foundation of the assessment of the good or bad of a servant before Allah SWT. a clean heart (qalb salim) will be able to deliver its owner to happiness in the world and the hereafter.

Abstract

When a unidimensionality assumption has been actually violated, interpretation of test scores might be jeopardized. It couldn’t be overemphasized in case of high-stake exams such as PAPs UGM (academic potentiality test for UGM graduate student candidates) which was supposed to reflect a composite ability. This study aimed at revealing item characteristics of PAPs A-1 Series based on UIRT and MIRT and discovering dimensionality of the three subtests of the test. Scores of subject (n=2035) on the 3 subtests were analysed and the results showed that 27 items (10 of Verbal, 8 of Kuantitatif, and 9 of Penalaran) were flagged for having rbis of less than 0.25 and 6 other items for having abnormally high pseudo-guessing parameters. Dimensionality analyses found out that Penalaran subtest was local-dependent while Verbal and Kuantitatif subtests both were local-independent. In addition, MIRT analyses failed to fully describe item characteristics of the test due to effect of interaction among probabilities of correct response of the three subtests. Keywords: dimensionality, PAPs UGM, MIRT, UIRT

Abstract

Penelitian ini dilakukan di SMK Bina Mandiri Sukabumi, Kabupaten Sukabumi. Penelitian ini bertujuan untuk mengetahui pengaruh pelaksanaan pelatihan terhadap kinerja guru pada SMK Bina Mandiri Sukabumi Kabupaten Sukabumi. Metode dalam penelitian ini menggunakan metode penelitian deskriptif dan metode asosiatif. Penelitian ini menggunakan data primer dengan menggunakan observasi serta menyebarkan kuisioner kepada responden. Teknik pengambilan sampling menggunakan non probability sampling. Jumlah sampel dalam penelitian ini sebanyak 34 responden. Untuk uji analisis pada penelitian ini digunakan uji validitas instrument, uji realibilitas kemudian dilakukan uji analisis statistic untuk analisis hubungan dan pengaruh digunakan analisis koefisien korelasi, analisis koefisien determinasi, analisis regresi. Berdasarkan hasil penelitian yang telah dilakukan dapat diketahui bahwa hubungan pelatihan terhadap kinerja guru memiliki hubungan yang kuat pada SMK Bina Mandiri Sukabumi Kabupaten Sukabumi. Besarnya kontribusi pengaruh pelatihan terhadap kinerja guru sebesar 59,99% sedangkan sisanya sebesar 40,01% dipengaruhi oleh variabel yang tidak diteliti diluar variabel pelatihan seperti kepemimpinan, motivasi, disiplin, kompensasi, lingkungan kerja dan lain-lain.

Abstract

Measurement process of concrete mold erectness (bekesting) and the floor slope was generally conducted using conventional method applying a plummet (pendulum) for bekesting erectness and waterpass for the floor slope. The drawbacks of this method are it requires a relatively longer processing time and the outcome of the slope measurement is not represented in degrees. The measurement of digital plummet and digital waterpass is easier as the measurement time is relatively short and the tilt angle is represented in degrees. This paper describes a design and implementation of digital plummet and waterpass using Accelero Sensor MMA 7361L based on microcontroller ATmega8. The Accelero sensor MMA 7361L was used to read the tilt axis x, y, and z with analog voltage output that is converted into digital form using the ADC on the microcontroller. Based on the results of tools test for bekesting erectness and floor slope measurement, it was obtained that the average error were 0.51% and 0.49% for x-axis and y-axis respectively.
