Control of Ae. Aegypti population is performed as an effort to suppress the transmission of dengue virus, one of the methods is sprinkling of temephos larvicide. Operational dose of temephos used in Indonesia (1 mg/L) is higher from recommended dose of WHO (0.012 mg/L). In East Java, commercial temephos are found to have different application doses of 8 g/L (8G) and 10 g/L (10 G). This study was designed to know the susceptibility of Ae. aegypti population from Jember (JEM), Surabaya (SBY), and Entomology Laboratory of Universitas Airlangga collection (LAB) towards temephos 8G and 10G starting at high (1 mg/L) to low concentrations(0.015625 mg/L). Larvae mortality test was performed based on WHO standard method with 4 times replication. Data was analyzed statistically. Results showed that the three groups of Ae. aegypti larvae had mortality level at >90% in the lowest concentration applied (0.015625 mg/L) at time threshold of 240 minutes, for both temephos8 G and 10 G. Significant difference of larvae mortality towards highest (1 mg/L) and lowest dose (0.015625 mg/L) was found in JEM, at both 8 G and 10 G doses, and LAB at 8 G dose. JEM and SBY groups were found to have resistance ratio 95 (RR95) to temephosat low category (<5) compared to LAB. All groupstill retained susceptibility towards commercial temephos larvicide at low dose (0.015625 mg/L). Based on results, we recommendedlowering the operational dose of larvicide temephos used for population control of Ae. aegypti vector population in East Java.

Batteries are one source of electrical energy that is still an important need in everyday life, especially for electronic equipment. Batteries are often used for daily activities, including for TV remotes, wall clocks, flashlights, and others. However, battery waste is very dangerous for the environment because it contains hazardous materials and requires proper handling to deal with it. One of them is the procurement of alternative batteries that are more environmentally friendly. Battery waste can be recycled using natural materials, one of which is using waste from banana peels. Banana peels contain ionizing properties and conduct electricity, making them suitable for use as an electrolyte paste that has optimal battery life. The processing of leather waste into alternative batteries (biobatteries) is carried out with partners from the residents of Sidotopo Wetan Village, Kenjeran District, Surabaya, as a community service program through three stages, namely the preparation, socialization, and practice stages. Then in the practical session, experiments were also carried out with the aim of knowing the voltage generated from the biobattery and the durability of the biobattery made from banana peel waste. In the experimental results in the practical session, it was found that banana peel waste can deliver electricity, so it can be used for electrolytics in commercial batteries which may be used as biobatteries. It is hoped that through this service program, it can provide provisions for community partners in overcoming battery needs through their own production to reduce the cost of purchasing batteries, as well as being able to update science and technology, so that community partners are able to create prosperous and competitive families. Baterai merupakan salah satu sumber energi listrik yang masih menjadi kebutuhan penting dalam kehidupan sehari-hari terutama untuk peralatan elektronika. Baterai seringkali digunakan untuk kegiatan sehari-hari, diantaranya untuk remot TV, jam dinding, senter, dan lain-lain. Namun, limbah baterai sangat berbahaya bagi lingkungan karena mengandung bahan berbahaya dan beracun yang memerlukan penanganan yang tepat untuk mengatasinya. Salah satunya dengan pengadaan baterai alternatif yang lebih ramah lingkungan. Limbah baterai dapat didaur ulang menggunakan bahan alami salah satunya menggunakan limbah dari kulit pisang. Kulit pisang memiliki kandungan yang dapat terionisasi dan menghantarkan listrik, sehingga cocok digunakan sebagai pasta elektrolit yang memiliki daya tahan baterai yang optimal. Pengolahan limbah kulit pisang menjadi baterai alternatif (biobaterai) dilakukan bersama mitra warga Kelurahan Sidotopo Wetan, Kecamatan Kenjeran, Surabaya, sebagai program pengabdian masyarakat melalui tiga tahapan yaitu tahap persiapan, sosialisasi, dan praktik. Kemudian di sesi praktik juga dilakukan eksperimen dengan tujuan mengetahui tegangan yang dihasilkan dari biobaterai serta daya tahan biobaterai yang berbahan dari limbah kulit pisang. Pada hasil eksperimen di sesi praktik didapatkan hasil bahwa limbah kulit pisang dapat mengantarkan arus listrik, sehingga dapat digunakan untuk menggantikan elektrolit pada baterai komersil yang berpotensi sebagai pembuatan biobaterai. Diharapkan melalui program pengabdian ini dapat memberikan bekal kepada mitra warga dalam mengatasi kebutuhan baterai melalui produksi sendiri untuk menekan biaya pembelian baterai, serta dapat menjadi pemutakhiran ilmu pengetahuan dan teknologi, sehingga mitra warga mampu menciptakan keluarga sejahtera dan berdaya saing.

The objectives of this study were to determine the effect of various fractions of mangosteen (Garcinia mangostana) pericarp extract to the changes of the fasting blood cholesterol and serum malondialdehyde (MDA) levels on diabetic mice (Mus musculus). Thirty 3-4 months old male mice strain BALB/c, weight 20-30 g were divided into six groups. The first group was KN as a non diabetic control group, KD as a diabetic control, KM as a group of diabetic mice treated with metformin, and NP, SP, and P as the treatment groups that were treated by using three different fractions from mangosteen pericarp extract, non polar, semi polar, and polar respectively. The induction of Diabetes mellitus was done by the injection of STZ, and the mice were given a high fat diet treatment to induce the hiperlipidemia condition using lard for three weeks. The blood cholesterol levels were measured in all groups before and after the injection of lard, and day 1, 7, and 14 of treatment as well. The serum MDA level as the indicator of lipid peroxidation were measured by using QuantiChrom TBARS Assay Kit (DTBA-100). The data of cholesterol levels were statistically analyzed by t-test, while the data of serum MDA levels were analyzed by variance analysis followed by Duncan test. The results showed that the polar fraction of mangosteen pericarp had effect to decrease the fasting blood cholesterol level in mice, however the non polar and semi polar fraction had no simmilar effect. All of the fractions has shown significant effect to decrease the serum MDA level in mice.

The education system is defined as a process of learning something new, where the process can develop the potential within and then increase student interest in learning Increasing students' learning interest will have a good impact on teaching and learning activities so that learning results can be achieved. The learning that has been carried out so far seems to be still less than optimal, while students are required to master all existing concepts, especially on Animal Tissue material. In addition, the lack of optimal learning media is one of the reasons why student learning results’ decline. For that, it takes a learning media that can act as a bridge to understanding the concepts. The purpose of this research was to describe the level of effectiveness and practicality of using the Make a-Match cards on Animal Tissue material. This research was quantitative descriptive research. The model used was ASSURE with six stages. This study used a one group pretest-posttest design. The trial was carried out at XI MIPA 4 SMAN 8 Surabaya. Research instruments included test sheets, validation, observation, and student responses. The results showed that the completeness indicator scores 75% in the complete category, validation scores 79.3% in the valid category, the implementation observation was 100% in the very good category, and student responses were 94.5% in the very practical category. Thus, the Make a-Match Card learning media can be used for the learning process at school.
