Pulau Kabung terletak di Kabupaten Bengkayang, Kalimantan Barat dengan jumlah penduduk 600 orang yang memiliki mata pencaharian utama sebagai nelayan. Kondisi cuaca yang ekstrim dengan gelombang tinggi mengakibatkan penurunan produktivitas hasil tangkapan, sehingga masyarakat melakukan aktivitas berkebun dengan memanfaatkan lahan yang ada. Cengkeh dan Pala merupakan komoditas perkebunan yang memiliki banyak manfaat di berbagai bidang. Namun, daun cengkeh yang berguguran dan limbah hasil pengolahan daging buah pala belum banyak dimanfaatkan dan cenderung menjadi sampah. Pelatihan pembuatan minyak atsiri dalam memanfaatkan limbah perkebunan telah dilaksanakan sebagai upaya pemberdayaan masyarakat. Dalam satu kali produksi membutuhkan bahan baku 200 kg dan proses destilasi selama 3-4 jam. Penyulingan daun cengkeh menghasilkan 4-5 L minyak, sedangkan daging pala menghasilkan 2-4 L. Minyak pala dijual dengan harga Rp. 20.000/botol ukuran 8 mL atau Rp. 750.000/L.

Coconut shell liquid smoke has been made from coconut shells by pyrolysis method at a temperature of 150 °C for 4 hours. Liquid smoke purified by adsorption using activated charcoal. The test results showed that activated charcoal could bring down the conciseness to become odourless and the color of liquid smoke from dark chocolate to yellowish-brown. The composition of the liquid smoke compound was determined by using the Gas Chromatography-Mass Spectrophotometer (GC-MS) consisting of 33.60% methylamine-D2 and 31.14% acetic acid as the dominant compounds. A solution of liquid smoke in water (6.0% v / v) was used for activity testing to the content of proximate by immersing fresh anchovy at room temperature with closed conditions for seven days. The results of the proximate test observed as follows: the water content tended to decrease, the highest on day 1 (11.56%) and the lowest on the 7th day (7.38%), the ash content tends to increase, the highest on the 7th day (9, 76%) and the lowest on the 1st day (6.52%), the fat content tends to increase, the highest on the 7th day (20.19%) and the lowest on the 1st day (9.72%) and the protein content is an increase, namely the highest on the 7th day (14.02%) and the lowest on the 1st day (10.20%). The water content decrease caused the ash content was increased as an indication of an enhancement in mineral content in the anchovy sample. Likewise, the water content decrease caused the higher fat content. Based on the results, it can be concluded that the liquid smoke produced from coconut shells purified by the activated charcoal is very promising as a foodstuffs preservative.

Kabung Island, which is located in the Bengkayang Regency Government area, is one of 226 small islands in West Kalimantan. Busy visits to the island during the school holidays and weekends have resulted in a large distribution of garbage in the waters and coasts of the island, and if it is not addressed promptly, it can cause global water problems. The Lecturer Team of the Department of Marine Affairs at the University of Tanjungpura as the implementation team of PKM activities to clean the beaches of Kabung Island, together with all the islanders and students of the Department of Marine Affairs, dive in cleaning the beaches and waters close to residential areas, sorting and collecting garbage, then burning and stockpiling it so that it does not get worse. accumulate and more and more enter the water bodies and can reduce the quality of the waters on the island. As many as 25 students were directly involved in the activity, and 20 residents from the island were directly involved in beach cleaning activities. From this activity, which is centered on the island of South Kabung, 100 kg of garbage has been collected consisting of plastic materials in the form of used drink bottles, stereoforms, pampers, and some trash carried from the middle of the sea, which may be carried away from the mainland coast. This activity is very necessary and is expected to continue as an annual routine activity of the Department of Marine Affairs, as a participation in preserving the sea and maintaining good water quality so that the diversity of species and population of a marine biota is not affected by the presence of these wastes. ===== Pulau Kabung yang berada dalam wilayah Pemerintahan Kabupaten Bengkayang merupakan salah satu dari 226 pulau kecil yang berada di Kalimantan Barat. Kunjungan yang ramai ke pulau tersebut pada musim liburan sekolah dan weekend, menyebabkan banyaknya sebaran sampah yang terdapat di perairan dan pesisir pulau tersebut, dan jika tidak diatasi dengan segera dapat menimbulkan masalah perairan secara global. Tim Dosen Jurusan Kelautan Universitas Tanjungpura sebagai tim pelaksana kegiatan PKM pembersihan pantai pulau Kabung, bersama dengan segenap masyarakat pulau tersebut dan mahasiswa Jurusan Kelautan, terjun membersihkan pantai dan perairan yang dekat dengan permukiman penduduk, memilah dan mengumpulkan sampah, kemudian membakar dan menimbunnya agar tidak semakin menumpuk dan semakin banyak yang masuk dalam badan perairan dan dapat menurunkan kualitas perairan di pulau tesebut. Sebanyak 25 orang mahasiswa terjun langsung dalam kegiatan dan 20 warga masyarakat dari pulau tersebut terlibat langsung dalam kegiatan pembersihan pantai. Dari kegiatan tersebut, yang dipusatkan pulau Kabung Selatan, terkumpul sampah sebesar 100 kg yang terdiri atas bahan plastik berupa botol bekas minuman, styrofoam, popok, dan beberapa sampah bawaan dari tengah laut, yang mungkin terbawa arus dari pesisir daratan. Kegiatan ini sangat perlu dan diharapkan berlanjut sebagai kegiatan rutin tahunan dari Jurusan Kelautan, sebagai peran serta dalam melestarikan laut dan menjaga kualitas perairan tetap baik sehingga keanekaragaman jenis dan populasi suatu biota laut tidak terpengaruh oleh keberadaan sampah-sampah tersebut.

Entikong is one of Indonesia's land border areas with Sarawak Malaysia, which is the gateway for economic and business activities. Despite being the front porch of a country, the fact is that the border areas of the State are very conditioned with lag. Limited access to public service resources and the inadequate community ability in processing natural resources including agriculture and plantations are the dominant factors influencing the lag of a border area. Bamboo is one of the abundant forest products in Entikong. The use of bamboo in the community is still limited to its use as building materials (scaffolding) and as a protective fence for plants in the gardens of the citizens. Bamboo Rope (Gigantochloa hasskarliana Kurz) species of bamboo found in the Entikong region, where elsewhere it generally makes it as a household handicraft material, but has not been used effectively in the entikong region. Community service activities aim to improve the skills of the Entikong community in processing bamboo plants as handicrafts of household goods of economic value so that it can be an additional source of income for the people on the border ===== Entikong adalah wilayah perbatasan darat Indonesia dengan Sarawak Malaysia, yang menjadi gerbang kegiatan ekonomi dan perniagaan. Meskipun menjadi beranda depan dari suatu negara, kenyataannya bahwa wilayah batas negara sangat sarat dengan ketertinggalan. Keterbatasan mengakses sumber-sumber pelayanan masyarakat dan kemampuan masyarakat yang tidak memadai dalam mengolah sumber daya alam termasuk pertanian dan perkebunan merupakan faktor yang dominan memengaruhi ketertinggalan sebuah wilayah perbatasan. Bambu adalah salah satu hasil hutan yang kelimpahannya besar di daerah Entikong. Pemanfaatan bambu dalam masyarakat masih terbatas pada penggunaannya sebagai bahan bangunan (perancah) dan sebagai pagar pelindung tanaman di kebun-kebun warga. Bambu tali (Gigantochloa hasskarliana Kurz.) adalah salah satu spesies bambu yang terdapat di wilayah Entikong. Di tempat lain umumnya menjadikannya sebagai bahan kerajinan rumah tangga, tetapi belum dimanfaatkan secara efektif di wilayah Entikong. Kegiatan Pengabdian kepada Masyarakat bertujuan untuk meningkatkan keterampilan warga masyarakat Entikong dalam mengolah tanaman bambu sebagai kerajinan alat-alat rumah tangga yang bernilai ekonomis sehingga dapat menjadi sumber penghasilan tambahan masyarakat di perbatasan tersebut.

Combining TiO2 and a semiconductor with a smaller band gap, such as Fe2O3, to form a heterojunction composite can increase its photocatalytic activity. In this work, the Fe2O3-TiO2/kaolinite composites were successfully synthesized by ultrasonic-assisted coprecipitation using titanium-tetraisopropoxide (TTIP) dan Fe (NO3)3.9H2O as precursors. Using kaolinite as a matrix also increases the photocatalyst’s surface area. The obtained Fe2O3-TiO2/kaolinite composites were characterized. The crystal phase was characterized using X-Ray Diffraction and resulted in anatase with a crystallite size average of 9,7 nm. Fourier Transform Infrared Spectrophotometer (FTIR) shows the peak at a wavenumber 574-1210 cm−1 ascribed TiO2 and Fe2O3 incorporated into kaolinite. The Optical properties show the absorption edge of Fe2O3-TiO2/kaolinite is redshift toward the visible light region. The result showed that the photocatalytic activity of Fe2O3-TiO2/kaolinite composites with heterostructure was more active than the corresponding Fe2O3 or pure TiO2 in the degradation of methylene blue under visible light illumination, which can degrade 83% for 180 minutes. Fe2O3 and kaolinite cause its synergistic effect as supporting materials. Furthermore, it indicates that the recombination of photo hole and photoelectron charge pair can be minimized. The Fe2O3-TiO2/kaolinite composite is a promising photocatalyst to degrade organic pollutants for wastewater treatment.

Tengkuyung (Cerithidea obtuse) is one of the many snails that live in mangrove areas, being a source of food and the economy, especially for people in coastal areas. Land and sea development and transportation activities have the potential to become a source of Pb contamination in tengkuyung and its environment. This study aims to determine the concentration of lead metal (Pb) in sediments and tengkuyung in the Kuala mangrove area of Singkawang City. Sampling was carried out at two station points. Measurement of heavy metal lead (Pb) in sediments and tengkuyung was carried out using atomic absorption spectrophotometry (SAA) method. The results showed that the content of lead (Pb) in the sediment and tengkuyung at station 1 was 0.0914 µg/g and <0.0070 (µg/g), while at station 2 it was 0.3927 µg/g and <0.0070 (µg/g). The content of Pb metal in tengkuyung meat still meets the eligibility for consumption because it is below the threshold according to SNI no. 7387 in 2009, which is 0.5 mg/kg (0.5 ppm).

Synthesis of composite boron-doped carbon nanodots (B-CDs)/TiO2 using the sol-gel method performed with titanium tetraisopropoxide (TTIP) precursor and B-CDs prepared by the microwave method using citric acid monohydrate, urea, and boric acid as precursors. The optimum concentration of boron dopant (B) on B-CDs/TiO2 is 0.5% boron (w/w) which is then used as a composite on TiO2 resulting in a brown solid and has blue luminescent under UV light. The result with UV-Vis/DRS for variation in B-CDs concentration of 0.5%, 1.25%, and 2.5% showed Eg values of 2.34 eV, 2.00 eV, and 2.29 eV. B-CDs cause the maximum emission peak (λEm) to redshift and affect the intensity of photoluminescence TiO2. The characterization of FT-IR does not indicate a new peak, there is no bonding in the B-CDs/TiO2 composite. The TiO2 diffractogram was observed to shift towards a larger 2θ which caused the crystallinity of TiO2 to decrease. Based on the photocatalytic activity test on the degradation of methylene blue solution, it showed fairly good activity. It is expected that the B-CDs/TiO2 composite has the potential to be applied as a photocatalyst to degrade organic pollutants under visible light illumination.

Humic acid (HA) in water can harm humans if it is regularly used or consumed. HA causes problems in the water, such as color, taste, and the formation of metal complexes. Therefore, it is necessary to degrade HA to address these problems. In this study, HA degradation was carried out using bismuth-doped TiO2 (Bi-TiO2) as a photocatalyst. The effect of Bi-TiO2 synthesized at various Bi concentrations and calcination temperatures on HA degradation was investigated and compared to pristine TiO2. Bi-TiO2 was synthesized via the sol-gel method and characterized using X-Ray Diffraction (XRD), Diffuse Reflectance Spectroscopy UV-Visible (DRS UV-Vis), and Fourrier Transform-Infra Red (FT-IR) Spectroscopy. The XRD analysis showed that the optimum calcination temperature was 500oC, with the highest crystallinity index (62.04%) and smallest crystallite size (11.95 nm). The DRS UV-Vis analysis showed that Bi-TiO2 1.5% led to the lowest band gap of 1.59 eV (λ = 782.33 nm), indicating that the photocatalyst was active under visible light irradiation. The FT-IR analysis showed an adsorption peak from the Bi-O bond at 802.39 cm-1, which caused a shift in the Ti-O-Ti adsorption peak. The photodegradation test was conducted using a 30 mL volume of HA solution 50 ppm and a 50 mg mass of catalyst. The results showed that Bi-TiO2 1.5% exhibited the highest efficiency in degrading HA, achieving 68.54% under visible light irradiation for 180 minutes. These results suggest the potential of Bi-TiO2 as an alternative method for treating HA in peat water using visible light irradiation.
