Analysis of Ganja Chemical Content (Cannabis Sativa L.) Discussion Results in the Aceh Regional Police Region Using the GC-MS Method

Cannabis (Cannabissativa L.) is an annual plant, which can grow and spread in tropical or sub-tropical regions with a height of one to five meters (Emcdda, 2015). Human selection is done for various uses and climate-influenced natural selection produces various varieties and chemical compositions. Analysis of the chemical content of cannabis (Cannabis sativa L) as a result of confiscation in the Aceh Regional Police, namely Lhokseumawe Regional Police, Pidie Regional Police, East Aceh Regional Police (Idi Rayeuk), Benar Meriah Regional Police and Central Aceh Regional Police (Takengon) were conducted by GC-MS method. Cannabis was extracted with n-hexane and marijuana extract was analyzed by GC-MS. ?9-THC and CBC compounds were found in all marijuana samples, CBN was found in 4 origin areas except Central Aceh Police Station, 2-Metoxy-5-isopropilaxy-7-propenylnaphthquinone was found in two police stations from Pidie Police and Central Aceh District Police. The biggest concentration of ?9-THC is 80.92% of the East Aceh Police Station; ?9-THCV is from two original police stations, namely East Aceh Police and Benar Meriah Police; CBN is the biggest 14.25% of Polres Benar Meriah; The biggest CBC is 10.98 from the East Aceh District Police.

Vannamei shrimp cultivation technology as an innovation of coastal land use in Rugemuk village Pulau Labu sub-district Deli Serdang district in 2019

This community service activity aims to increase the ability of fishermen and apply appropriate technology to cultivate Vannamei shrimp in a sustainable manner so that it will improve the welfare of fishermen's families. To achieve the objectives, several stages of activities are carried out, the first stage of the survey is to find out how the fish cultivator fishermen groups carry out their activities. The second stage is the socialization of activities that will be carried out to increase the ability to grow shrimp so that the results in a long time can increase the income (economy) of the fishermen. The third stage is to carry out coaching and counseling related to shrimp farming and can make decisions in the next economic field. This service program is carried out within 6 months. Program targets and outcomes (1). Increased knowledge and skills on appropriate technology in conducting Vannamei shrimp cultivation (2). Increased Vannamei shrimp yields by conducting shrimp culture training using tarpaulins. (3). In the long run, the results of aquaculture increase the economic welfare of the fishermen's family

PERBANDINGAN KANDUNGAN ASAM SINAMAT DAN ASAM BENZOAT DALAM KEMENYAN (Styrax benzoin) KUALITAS I,III DAN V YANG DIPEROLEH DARI DAERAH TAPANULI UTARA DENGAN METODE KROMATOGRAFI GAS

AbstractA research has been done about the comparation of the cinnamic acid and benzoic acid content in the frankincenses (Styrax benzoin) quality I, III and V which of obtained from Pangaribuan region (North Tapanuli). The cinnamic acid and benzoic acid content are analyzed by using Gas Chromatography with injection volume 1 µl. The data is analyzed qualitatively by measuring the retention time standard solution, with cinnamic acid and benzoic acid content are determained by using calibration curve with linier regretion from least square method. The result show the cinnamic acid and benzoic acid from the frankincenses class I is 26, 4303 %, and 3,3573 %, frankincenses class III is 26,0270%  and 2,0705%, frankincenses class V is 0,2884% and 1,5916%.Keywords : Frankincenses, cinnamic acid, benzoic acid, Gas Chromatograph

The Study of Degdradation Cable Isolation of PVC (Polyvinil Chloride) : A Comparison of Isolation Cable Between Short Circut and Open Flame

Research about The study of degdradation cable isolation of PVC (Polyvinil Chloride) : A comparison of isolation cable between short circut and open flame was carried out. The purposes of this research are i) to know degradation process of cable isolation from melting to be short circut occurring and ii) to know comparison of fire cable due to overload or open flame. This research is experimental laboratory whereas cable “NYA” size 1x1.5mm used as sample. Subsequently, samples are divided as: i) normal sample (without electric current) (as well as reference); (ii) samples were flowed by using  Electrical current 16, 25 dan 35 Ampere, respectively; iii) Sample was flowed by using electrical current until short circuts occurred,  and  iv) Sample was burned  by open flame. All samples were characterized with FTIR, SEM-EDS and XRD, respectively. The results showed that: i) FTIR Data. FTIR Spectra of short cable significantly changing compared to normal cable isolation. It means, flowing electric current to the cable caused temperature of cable will be increased, it may initiated oxidation occurred at functional group of esther which was existed in cable isolation;  ii) SEM EDS Data.  Supply of electron into cable caused overheating at cable, whereas degradation process for cable isolation occurred. The continuity of degradation will result pyrolisis (carbonization) at surface of isolation. Therefore SEM image proved that increasing of electron supply at degradation process  will be accelerating pyrolisis process; and iii) XRD Data. Increasing current electric will be increasing intensity of carbon (number of carbon atoms increased) and decreasing intensity the number of oxygen atoms (number of oxygen atoms increased). All of data indicated when open flame happened at cables so the number of oxygen will be increased, whereas carbon has been burned. Based on all data concluded whereas degradation process of isolation cable by giving overload of electrical current it clearly showed that significantly differences with cable isolation   of open flame. It may be concluded that the burning cable isolation of open flame was caused by degradation functional group. On the other side cable of open flame, the number of carbon will be decreased.

Fabrication of silica-based chitosan biocomposite material from volcanic ash and shrimp husk by sol gel method for adsorbent of cadmium (II) Ions

387-394The utilization of volcanic ash and shrimp shell waste into composite material is very interesting to discuss as a strategy to make naturally available materials into valuable, stable and low cost adsorbent. The study is aimed to fabricate the silica-based chitosan biocomposite material from volcanic ash of Sinabung mountain and shrimp husk by sol gel method to be used as an adsorbent. The procedure is performed by converting volcanic ash into silica salt, extracting the chitosan from shrimp skeleton, and the synthesis of the silica-chitosan biocomposite by mixing the silica with chitosan in the aid of bifunctional glutaraldehyde cross-linking agent. The silica-based chitosan composite is successfully prepared from the mixture of 20 mL 58% (v/v) Na2SiO3 with 2% (w/v) chitosan to obtain biocomposite material (SChC1). A rapid and simple method to bind the silica with chitosan is achieved. The resulting biocomposite is amorphous, in the form of small crystals, a rough surface with a large pore area between 2θ = 20-24°. Adsorption capacity of the biocomposite material has been evaluated, where it has the capability to bind cadmium ion due to the presence of amine group in the material surface. The prepared material of silica-chitosan biocomposite has the potential to be used as an adsorbent
