Program pemberdayaan petani hutan untuk konservasi dan restorasi ekosistem yang telah dilakukan oleh Pemdes Jetak Kecamatan Montong kabupaten Tuban pada tahun 2022 dipandang cukup efektif untuk memanfaatkan lahan di bawah tegakan hutan, namun kesinambungan program dalam bentuk pelestarian masih terus diperlukan. Pelestarian kawasan konservasi pengelolaan hutan masih perlu digalakkan agar terjadi keseimbangan ekosistem. Di lain pihak tumbuhnya kelompok usaha baru sebagai sumber penghasilan rumah tangga di luar sektor pertanian (batik, makanan dari produk pertanian, dan pewarna alami batik). Namun masih mengalami beberapa kendala yang berkaitan dengan produksi daun tanaman, manajemen produksi pewarna batik, legal formal ijin usaha, brand produk dan pemasaran digital. Untuk itu perlu penguatan usaha desa sebagai program yang dapat mengatasi kendala tersebut.  Di bawah tegakan pohon masih banyak lahan yang pengelolaannya kurang maksimal sehingga berpotensi dikelola untuk tanaman indigofera tinctoria sebagai bahan baku pewarna alami kain batik dengan inovasi teknologi pemupukan yang menerapkan biochar. Program bertujuan untuk mengoptimalkan pemanfaatan lahan dengan budidaya tanaman di bawah tegakan hutan serta penguatan usaha desa. Optimalisasi pemanfaatan lahan dilakukan dengan scalling up agroforestri kopi. Penguatan usaha desa dilakukan dengan pelatihan dan pendampingan legal formal perijinan, branding produk, dan pemasaran digital. Hasil dari program ada penambahan agroforestry kopi dari 3.000 pohon menjadi 4.500 pohon, ada formal legal ijin usaha desa, dan tersedia toko online untuk produk desa. Agar ekosistem hutan lindung terjaga maka program konservasi perlu terus diupayakan. Disamping itu sebagai program keberlanjutan usaha desa, maka Pemdes perlu mendorong pelaku usaha agar memanfaatkan toko online yang tersedia.

This community service activity aims to provide a solution for several mosques that do not have large areas of land when carrying out sacrificial services. Of course, some problems must be solved, such as how to carry out sacrificial activities by minimizing risks and not requiring large areas of land. The solution offered is when slaughtering sacrificial animals using a portable cow thrasher. The advantage of using a trestle is that laying down the cow when it is about to be slaughtered does not require many people, nor does it require a large area to lay the cow down. The area used for slaughtering is not so dirty because the blood can be poured into one place. Slaughtering was very fast, seven cows were slaughtered until the meat was separated, it only took approximately 3.45 hours. Cows do not get angry and go on a rampage, making it easier for the slaughter team to slaughter them.

This study aims to analyze leverage as proxied by the debt to equity ratio, sales growth and firm size to financial performance as proxied by return on asset. This research was conducted on companies in the Consumer Non-Cyclicals Sector Food and Beverage Sub Sector, which were listed on the Indonesia Stock Exchange for the 2019-2022 period. The sampling method in this research used a purposive sampling method with a sample of 30 non-cyclical consumer sectors, food and beverage sub-sectors that met the sample criteria. This study used multiple linear regression analysis techniques and used SPSS statistical test tool version 22.0. The results of this study show that the variable leverage and firm size have a negative and significant effect on return on assets, while sales growth does not affect return on assets.

Neonatal mortality consists of early neonatal death and late neonatal death. Neonatal mortality rate is the number of neonatal deaths per 1,000 live births. Low Birth Weight is one of the risk factors that contributes to infant mortality, especially during the neonatal period. This study aims to determine the factors that influence the incidence of low birth weight babies at RSKDIA Siti Fatimah Makassar in 2024. This study is analytical with a case control approach used to determine the influence between independent variables and dependent variables. The type of research is retrospective which tries to look back. This means collecting data starting from the effects or consequences that have occurred. Then from these effects the causes or variables that influence these consequences are traced. The population in this study were all babies born in January-June 2018, totaling 759 babies. The sample in this study were babies born in the delivery room of RSKDIA Siti Fatimah Makassar in 2024 with a birth weight of > 2500 grams. Based on the research results, a p value of 0.002 was obtained, thus it can be concluded that this figure means that there is an influence of maternal age on the incidence of LBW, and the p value ? = 0.001 means that H0 is rejected, meaning that there is an influence between nutritional status and the incidence of Low Birth Weight.

The Child Identity Card (KIA) policy is one of the policies that has been issued by the government in accordance with Minister of Home Affairs Regulation Number 2 of 2016. The policy regarding child identity cards (KIA) started in 2016 in each Regency/City, while the implementation of this policy is implemented in Karimun Regency itself started in May 2018. In its implementation there were several problems that emerged where there were still many children under the age of 17 who still did not have a child identity card (KIA), of course this was not in line with the number of children in Karimun Regency which each year is increasing. The aim of this research is to determine the implementation of the child identity card (KIA) policy and to find out what are the inhibiting factors. The research method used in this research is a qualitative descriptive method. The data collection techniques used were observation, interviews and documentation. This research uses the main theory of Edward III, seen from 4 variable indicators that can influence the implementation of a policy. The results of the research show that the implementation of the child identity card (KIA) policy by the Population and Civil Registration Service of Karimun Regency, when viewed from the communication aspect, has run optimally. Judging from the aspect of resources, it is quite competent, and in terms of quality it is adequate. Judging from the disposition aspect, the officers/employees uphold high enthusiasm in implementing policies and carrying out their assigned tasks. Then, if we look at the bureaucratic structure aspect, officers/employees can always manage well in collaborating with each other. The inhibiting factor in this research is that the availability of budget to finance blanks is still relatively lacking, many applicants for child identity cards (KIA) have not yet completed the requirements, so this makes it difficult for officers/employees to process them.
