Abstract

Komposit serat alam adalah material yang sangat baik karena sangat ringan, kuat, murah, mudah di bentuk dan ramah lingkungan. Pohon gaharu (Aquilaria malaccensis) menghasilkan resin berbau harum untuk pembuatan parfum. Selain resin juga menghasilkan serat halus yang bisa dijadikan penguat material komposit. Tujuan penelitian untuk mendapatkan efek perendaman serat kulit gaharu terhadap pengujian mekanik menggunakan matriks polyester BQTN 157 serat gaharu sebagai penguat dan apakah komposit serat gaharu ini bisa dijadikan bahan alternatif pembuatan dashboart mobil. Metode penelitian menggunakan full Faktorial dengan dua faktor dan tiga level. Parameter proses yaitu perendaman dengan cairan kimia NaOH 2%, 4% dan 6% dan lama perendaman 120 menit, 240 menit dan 360 menit. Hasilnya nilai rata-rata kekuatan tarik maksimum yaitu 42,0 Mpa pada serat dengan waktu perendaman selama 120 menit dan 2% NaOH. Hasil pengujian impak maksimum sebesar 39,1 kj/m2 pada waktu perendaman 120 menit dan persentase NaOH 4%. Hasil foto menghasilkan bentuk patahan broken fiber dimana serat yang patah dipenuhi dengan serat halus dan berserabut. Efek persentase NaOH dan perendaman serat gaharu lebih dari 240 menit membuat kekuatan serat menjadi menurun, mudah putus dan rapuh. Artinya persentase NaOH dan perendaman tidak boleh lebih dari 240 menit. Hasil pengujian ini bisa dijadikan material baru untuk pembuatan dashboard mobil karena sudah standar bila dibandingkan dengan standar.

Abstract

This PKM activity aims to increase the income of the community, especially housewives in Sungailiat District, Bangka Regency. The program carried out is processing coconut coir into pots and cocopeat. Sungailiat District has a lot of coconut tree plants belonging to the surrounding community, especially in the coastal area. One of the partners for PKM activities is Mr. Karyadi, whose address is in Rebo Village, Sungailiat District, Bangka Regency. Problems that arise in the production process include the length of time required for the process of taking coconut coir and cocopeat powder, which is ± 10 days. Because the process of taking it must be soaked and beaten. The implementation of this activity is carried out by field observation, machine design, machine manufacturing, operation and maintenance training and monitoring and evaluation. The results of this PkM show that the manufacture and procurement of coco decomposing machines for partners has been well realized. There is still a process left because there is an outer part of the coconut husk that is still attached to the machine. This is due to the distance between the wall and the crushing blade having a distance of approximately 15 mm.

Abstract

Ampiang is an authentic Bangka Belitung food made from tapioca, fish, water, salt and flavorings. Then in a round and thin shape with a diameter of 70 mm. You can find Ampiang bus at a warung or supermarket in Bangka Belitung. The objective of the Community Partnership Program (PKM) for the ampiang-making community groups is to improve the quality and production capacity of ampiang for partners. A survey has been conducted on ampiang making partners in Sinar Baru Sungailiat Village under the name "Ampiang Ikan Ciu Yu Erin". The problem that occurs to these partners is that the production equipment for the ampiang oil dryer at the partner is still manual, namely coating old paper or newspapers in the hope of reducing oil. So that ampiang does not last long and quickly causes mold and unpleasant odors. The method used is to make an Ampiang dryer with a capacity of 15 kg/process, which has a portable form so that it is easy to move around and conducts brief training on how to use and maintain an oil dryer. It is portable so it is easy to move around. As a result, Partners can increase the production of ampiang and this machine is able to produce ampiang which is more durable, more than 5 months. Based on the test results with a capacity of 15 kg Ampiang, 1000 rpm rotation, processing time of 5 minutes produces an average of 14.45 kg of dry Ampiang and 0.52 oil that has been separated. This means that every 1 kg of ampiang produces 0.036 kg of oil. This oil is what makes ampiang not durable and causes an unpleasant odor. This is also evidenced by the evaluation of ampiang's resistance for 5 months that has not shown any fungus attached to the ampiang.

Abstract

Red bricks are the most easy material to locate and use practically any building. Besides being cheap, red bricks are also often used because of their easy and plentiful production processes in all parts of Indonesia. Brick use in both construction and non-construction or structure needs to be increased products produced, either by improving the quality of the red brick matality or additions to other materials.. Based on sni 15-2094-2000, red bricks are a rectangular prism material, solid or perforated with a hole volume ata maximum of hole volume at 15% and are used for constructing walls of buildings, which are made of clay with or without active material and burned ata certain temperature. The study was done using the RSM method of using soft prelims. The data processing produced 20 samples with six times the repetition in the center. The results of this study were the result of the highest impaction in experiments 14, 122.9 kj/m2, with a 8-day drying parameters, a temperature of 968.18oc with a 10-hour heat span and the lowest impact on experiment 12 was 47.6 k Kj /m2 with the long drying parameters of 8 days, places up to 800oc and a length of warming 3.27 hours this is due to the long drying and long warming. Based on shem's test, the exact difference in the form of breaking the value of the broken impak tests shows that the surface has become crystalline with perfect uniform. even though some of the parts are cracked, it is because the water contained less than the lower intake, which forms the crystals at least 50%, while in some areas there is a portation or hole in which the convergence is still incomplete.

Abstract

Red brick is a very important building material in building construction. Red brick has a rectangular physical shape with a distinctive color, namely red. Red bricks are made of clay mixed with sand and water, then mixed evenly and molded as desired. According to the quality standards, red brick is said to be of good quality and quality if it has several criteria including having the required size, compressive strength, and water absorption capacity. This research was conducted to see the effect of the length of drying time after printing, the effect of heating time, heating temperature, and the surface topography of red brick. The data processing method uses the Response Surface (RSM) method using Design Expert 09 software. The results show the smallest compressive test value of 131.4 kg/cm2. The biggest value is 148 kg/cm2. The most significant influence on the red brick making process is the drying time. The longer the drying process will cause the water content in the red brick to decrease. The SEM results show that the effect of drying red bricks that experience longer drying will coalesce and crystallize more easily. Based on the analysis of the results of the study that a longer drying time will cause an increase in compressive strength.

Abstract

Mental health is important because mentality greatly influences a person's quality of life. The mental hospital is the only government agency that provides MMPI test services in Bangka Belitung. The MMPI is a self-report inventory of 550 true/false items that have historically been used to assess test takers' personalities, as well as their personal and social adjustments. The obstacle faced at this RSJ is that it still uses a manual registration system to carry out registration services for participants who take the MMPI test. Automatically this causes an accumulation of registrants who want to register, especially since the registration system used still uses paper forms. Based on these problems, an information system is needed to facilitate registration and data collection. The method used is the prototype method which consists of the stages of gathering requirements, building prototypes, evaluating, coding and testing. System design is carried out using the Unified Modeling Language (UML) method which consists of Use Cases, Entity Relationship Diagrams, and Activity diagrams. System testing is carried out using the UAT BlackBox Testing method and the Technology Acceptance Model (TAM). The results of the BlackBox test show that 100% of the system works perfectly, while the TAM test shows that 88.22% of respondents feel the system is easy to use and not complicated, 85.33% of respondents have an interest in using the system, and 88.33% of respondents feel the system provides benefits and has used for the registration process.
