Abstract

 Penelitian ini bertujuan untuk mengetahui kapasitas batang tekan dengan variasi penampang siku tunggal dan siku ganda; Mengukur perpindahan yang terjadi pada tengah bentang batang tekan; Mengetahui faktor panjang tekuk batang tekan dan membandingkan beban tekan maksimum hasil pengujian laboratorium dengan SNI 1729-2015. Penelitian ini menggunakan profil siku tunggal L30.30.3 dan profil siku ganda 2L30.30.3. Alat sambung yang digunakan adalah sambungan baut. Struktur terdiri dari 2 elemen, yaitu elemen horizontal  dan elemen diagonal yang dirangkai membentuk struktur rangka batang. Pembebanan diberikan pada pertemuan batang horizontal dan diagonal dengan arah pembebanan searah gravitasi. Penambahan beban diberikan secara bertahap sampai benda uji mengalami kegagalan. Hasil penelitian  diperoleh nilai kapasitas batang tekan (horizontal) siku tunggal dan ganda berturut-turut sebesar 22,452 KN dan 48,849 KN.  Perpindahan terbesar terjadi pada bagian leg yang tersambung langsung pada pelat buhul adalah siku tunggal yaitu sebesar 43,880 mm. Nilai faktor panjang tekuk (K) pada benda uji siku tunggal diperoleh sebesar 0,8303 dan pada benda uji siku ganda diperoleh sebesar 0,7243.

Abstract

This research aims to analyze the role of raskin (poor rice) policy toward household expenditurepattern and household response toward the policy of Raskin food card replacement in Bandar Lampung City. The numbers of respondents in this research were 137 respondents that were determined by accidental sampling method. The data was analyzed by descriptive analysis, different test and cross tabulation. The results showed that there was reduction of household expenditure burden for grainafter receiving Raskin subsidy that was equal to 4.69 percent. There was consumption escalation of vegetable protein sources (1%), animal protein sources (2.22%) and fruit (1%) of households in Bandar Lampung City after receiving Raskin subsidy. Household non-food expenditures, such as household needs, clothing, housing and telecommunications were increased by less than 1 percent. The factors that affected household responses in Bandar Lampung City to food card policy was the number of dependents and income, while the age and education of respondents did not affect the response of households in Bandar Lampung to Raskin card policy.Key words: expenditure pattern, food card, raskin

Abstract

This research aims to analyze coffee farming income in Tanggamus District, behavior of coffee farmers in managing environmental risk, and factors that influence behavior of coffee farmers in managing environmental risk. This research was conducted in Sinar Sekampung Village, Air Naningan Sub-District and Gunung Meraksa Village, Pulau Panggung Sub-District in August 2017. The sample in this study involved 44 certification coffee farmers chosen using cluster random sampling method and 24 noncertification coffee farmers chosen using census method. The difference of coffee farming income is analyzed using Independent Sample t-test, while the difference of behavior is analyzed using Mann Whitney Test and the factors is analyzed using binary logistic regression. The results showed that there was no difference in coffee farmers income between certification farmers and noncertification coffee farmers. Sixty-three percents of certification coffee farmers were risk takers and 87,50% of nonacertification coffee farmers were risk neutral. Factors that influence behavior of coffee farmers in managing environmental risk were land area, coffee farming income, and participation of farmers in 4C certification program.Key words: coffee certification, environmental risk, coffee farming income

Abstract

Pentingnya pelajaran membaca dalam sistem pendidikan tidak dapat disangkal bahkan sukses atau tidaknya usaha pendidikan seseorang seringkali ditentukan oleh sukses atau tidaknya siswa dalam membaca. Keterampilan membaca yang diperoleh melalui pelajaran membaca di sekolah tidak akan banyak artinya manakala dalam dirinya tidak tumbuh minat dan selera terhadap membaca. Prestasi belajar adalah suatu hasil yang telah dicapai dengan cara melakukan kegiatan untuk mengetahui, menguasai pengetahuan, kemampuan kebiasaan, ketrampilan dan sikap melalui hubungan timbal balik antara orang yang belajar dengan lingkungannya. Agar siswa merasa lebih yakin dan dapat melihat prestasi belajarnya secara nyata.

Abstract

The Moringa plant, a tropical species, exhibits prolific growth and is abundantly present in Indonesia and other tropical regions worldwide. An extended lifespan, continuous flowering, and a high tolerance for elevated temperatures characterize it. Utilizing its components, including leaves, bark, seeds, and roots, this multifaceted plant is renowned for its therapeutic properties. The plant's antioxidants and various nutrients, including vitamins and minerals (iron, magnesium, vitamin B6, vitamin B2, vitamin C, and vitamin A), have led to studies on the plant's potential health benefits. In order to develop the local economy in Ulakan village, Padang Pariaman Regency, Moringa plants were processed by using the plant leaves to manufacture herbal tea, which can then be sold. This community service program was significant given the widespread presence and ease of cultivation of Moringa plants within the local region. The program involved the planning and selection of the activity site, the implementation of training sessions, and the assessment of the program's outcomes. The result of this community engagement initiative was the demonstrated interest of many participants in producing Moringa leaf tea.

Abstract

Many rivers in Indonesia had very poor water clarity due to a mixture of dirt and mud in the water. Polluted rivers were often found in areas near settlements, where household waste that flowing into rivers made the water look dirty and turbid. Pollutants dissolved in water will bind to small particles and settle at the bottom of the river, due to sedimentation. This research designed a device to detect sediment volume in the rivers. This device used an ultrasonic sensor type DYP-L04 and a rotary encoder for calculating volume, with Arduino Mega 2560 R3 as a processor. There is a PG45 motor that was used to set the motor speed to be constant. This ultrasonic sensor works based on the Arduino programming algorithm that has been designed, so that the device can measure sediment volume optimally. The results of this research showed that the device could determine the volume of sediment with the average error score less than 10 %.

Abstract

The PG45 DC motor is a drive system used on sediment detection boat. To achieve the desired stability and speed, it is necessary to apply a control system to the sediment detection boat drive system. Control systems need to be tuned to ensure that they function properly and are responsive to changes. In order to complement the previous research, further research was carried out focusing on determining the PID control parameters on the angular speed of the PG45 DC Motor using Simulink. The PG45 DC motor works based on the Arduino programming algorithm that has been designed so that it can rotate at a predetermined speed. This research modeled the sediment detection ship system on Simulink with a similarity rate of 94.09%. The results of this study indicate that the tuning method used, namely trial and error, produces good control on the sediment detection ship system model that has been assembled in Simulink with the value of Kp = 100; Ki = 5; Kd = 15 obtained the value of rise time = 0.2474 seconds and settling time = 0.4104 seconds and overshoot = 0.2175%%.
