Abstract

Pemanfaatan limbah batok kelapa sangat diperlukan mengingat tingginya hasil limbah batok kelapa yang dihasilkan di Indonesia, salah satunya untuk substitusi agregat pada campuran beraspal. Penggunaan batok kelapa sebagai agregat dalam konstruksi perkerasan aspal diharapkan dapat menghasilkan perkerasan yang awet, murah dan ramah lingkungan. Penelitian ini bertujuan untuk mengetahui karakteristik sifat mekanis atau modulus resilien pada campuran aspal yang bergradasi menerus (AC-BC) dengan menggunakan batok kelapa sebagai pengganti agregat. Berdasarkan hasil uji propertis  yang telah dilakukan dapat diambil sebuah kesimpulan sebagai berikut material agregat dan aspal memenuhi persyaratan sebagai agregat campuran aspal panas berdasarkan Spesifikasi Bina Marga Tahun 2018. Untuk material batok kelapa gumpalan  lempung dan butir mudah pecah dalam agregat masih dalam tahap pengujian. Terhadap nilai modulus resilien campuran AC-BC yang mengandung kelapa sebesar 5%  lebih superior dibandingkan dengan tanpa batok kelapa di temperature pengujian 45°C. Dalam pengujian modulus resilien mengambil hanya satu temperature saja yaitu 45°C, hal ini di karenakan Indonesia adalah negara tropis yang mana suhu di Indonesia cukup tinggi pada daerah-daerah tertentu.

Abstract

Normal concrete is another building material that is most widely used in the construction industry. Concrete is meant by reinforcing steel (wire, woven wire) in the concrete cross-section to improve tensile and flexural resistance. The concrete section transfers tensile stress to the reinforcing steel section, which has better tensile strength. Polymer materials that are more resistant to rust can also be used as reinforcement materials. Basically, concrete is made from a mixture of aggregates (fine and coarse), cement, water, and additives. In a concrete mix, the fine and coarse aggregates are bound to the cement matrix. The cement reaction between water and minerals in cement produces a strong matrix, holds the aggregate in place and gives the concrete compressive strength properties. In the current industrial era, material selection for a normal concrete feasibility test is quite challenging due to finding quality materials. Through a series of material feasibility tests for normal concrete mixtures, it is hoped that quality control will be in the use of superior materials. This research was conducted at the Laboratory of PT Jaya Beton Indonesia. Based on the properties test data on the aggregate and concrete materials, it can be concluded that the aggregate materials have met the specifications of the Indonesian National Standard and IJASE. So that the material can be used in the normal concrete mix plan stage (job mix formula) regarding the provisions of the grain gradation using the normal concrete manufacturing method listed in SNI 7656 of 2012 concerning Procedures for Making Normal Concrete. From the results of the trial mix of concrete in Table 20, the authors decided to use the concrete quality f'c 30 MPa with consideration of the effects of the compressive strength of the concrete being relatively stable in terms of deviation.Keywords: test aggregate properties, normal concrete aggregates, material characteristics, concrete mix

Abstract

Masalah stunting (balita pendek) di Indonesia menempati posisi tiga besar di Asia Tenggara dengan prevalensi stunting tahun 2005-2017 mencapai 36,4%. Sedangkan prevalensi obesitas di Indonesia 21,8% dan diprediksi mencapai 40% pada tahun 2030. Hal ini disebabkan oleh pemahaman yang salah dari masyarakat terkait stunting yang cenderung dikaitkan dengan faktor keturunan (genetik), pola makan, pola hidup dan tingkat pemahaman akan nutrisi di kalangan masyarakat. Padahal stunting dan obesitas lebih disebabkan oleh faktor perilaku (pola makan dan pola hidup), faktor lingkungan dan faktor layanan kesehatan. Sosialisasi dan edukasi pola makan dan pola hidup sehat berbasis riset biopigmen kepada masyarakat yang tidak produktif secara ekonomi tetapi memegang peran kunci dalam keluarga yakni ibu dan pengelola komunitas sangatlah penting. Status gizi anak sangat dipengaruhi oleh pemahaman orang tua yang biasanya berperan penting dalam mengatur kesehatan dan gizi keluarga. Edukasi dalam bentuk seminar dan workshop dapat membangun pemahaman dan upaya peningkatan kesehatan gizi anak dan keluarga. Program Kemitraan Masyarakat yang dilakukan bertujuan untuk mendukung program mitra yaitu pengelola Ruang Publik Terpadu Ramah Anak (RPTRA) dalam mensosialisasikan pesan pencegahan stunting dan obesitas kepada masyarakat. Kegiatan peningkatan pemahaman dilakukan melalui seminar dan workshop selama dua hari. Salah satu metode yang digunakan untuk mengukur tingkat pemahaman peserta setelah mengikuti seminar dan workshop melalui in depth reflection berupa gambar yang memuat hal apa saja yang telah peserta dapatkan selama mengikuti kegiatan ini. Hasilnya menunjukan peserta dapat mengambil kata-kata kunci dan visual yang akrab dengan kegiatan sehari-hari, dari materi yang disampaikan oleh narasumber. Komposisi gambar yang menarik dan mudah dipahami ditentukan dari pesan yang dibuat singkat serta sederhana. Selain itu, gambar yang sering muncul adalah gambar yang sering ditemui sehari - hari. Temuan lainnya adalah pesan yang dituangkan dalam gambar tidak dapat berupa aspek sikap atau psikologis. Aspek tersebut dapat digambarkan melalui roleplay yang direkam dalam bentuk video. Kata kunci— stunting, obesitas, biopigmen, in depth reflection, RPTRA The problem of stunting in Indonesia occupies the top three positions in Southeast Asia with the prevalence of stunting in 2005-2017 reaching 36.4%. While the prevalence of obesity in Indonesia is 21.8% and is predicted to reach 40% by 2030. This is due to a mis-understanding of the society regarding stunting that tends to be associated with heredity (genetic), diet, lifestyle and the level of understanding of nutrition among the community. Whereas stunting and obesity are more caused by behavioral factors (diet and lifestyle), environmental factors and health care factors. Socialization and education of healthy eating and lifestyle based on biopigment research to communities that are not economically productive but play a key role in the family, namely mothers and community managers are very important. The nutritional status of children is greatly influenced by the understanding of parents who usually play an important role in regulating family health and nutrition. Education in the form of seminars and workshops can build understanding and efforts to improve the nutritional health of children and families. The Community Partnership Program aims to support partner programs, namely the manager of Child-Friendly Integrated Public Spaces (RPTRA) in socializing the message of stunting and obesity prevention to the community. Understanding improvement activities are carried out through seminars and workshops for two days. One of the methods used to measure the level of understanding of participants after attending seminars and workshops through in depth reflection in the form of images that contain what participants have gained during this activity. The results showed participants were able to take keywords and visuals that are familiar with daily activities, from the material delivered by the source. The composition of an attractive and easy-to-understand image is determined from a message made short as well as simple. In addition, images that often appear are images that are often encountered every day. Another finding is that the message poured out in the image cannot be either an attitude or psychological aspect. This aspect can be described through roleplay recorded in the form of video.

Abstract

Geopolymer concrete has decent strength, but it is still lower compared to conventional concrete. One way to improve the strength of geopolymer concrete is by adding reinforcing fibers. The fibers used should be suitable for the environmental conditions and economical. One fiber that can be used to enhance the strength of concrete is steel fiber. The addition of steel fiber to concrete can increase its density but may decrease the slump value, which can affect the workability of the concrete. In BGP 1%, the increase from 0% fiber content reaches 3.2%, and in BGP 2%, it reaches the maximum density of 2405.73 kg/m3 with the addition of fiber to geopolymer concrete. From the results, it can be observed that as the density of geopolymer concrete increases, the slump value tends to decrease.
